media: docs: move uAPI book to userspace-api/media

Since 2017, there is an space reserved for userspace API,
created by changeset 1d596dee3862 ("docs: Create a user-space API guide").

As the media subsystem was one of the first subsystems to use
Sphinx, until this patch, we were keeping things on a separate
place.

Let's just use the new location, as having all uAPI altogether
will likely make things easier for developers.

-
-.. code-block:: c
-
-    #include <sys/ioctl.h>
-
-
-.. c:function:: int ioctl( int fd, int request, void *argp )
-   :name: cec-ioctl
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``request``
-    CEC ioctl request code as defined in the cec.h header file, for
-    example :ref:`CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`.
-
-``argp``
-    Pointer to a request-specific structure.
-
-
-Description
-===========
-
-The :c:func:`ioctl() <cec-ioctl>` function manipulates cec device parameters. The
-argument ``fd`` must be an open file descriptor.
-
-The ioctl ``request`` code specifies the cec function to be called. It
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes.
-
-Macros and structures definitions specifying cec ioctl requests and
-their parameters are located in the cec.h header file. All cec ioctl
-requests, their respective function and parameters are specified in
-:ref:`cec-user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-Request-specific error codes are listed in the individual requests
-descriptions.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-=========
-
-``device_name``
-    Device to be opened.
-
-``flags``
-    Open flags. Access mode must be ``O_RDWR``.
-
-    When the ``O_NONBLOCK`` flag is given, the
-    :ref:`CEC_RECEIVE <CEC_RECEIVE>` and :ref:`CEC_DQEVENT <CEC_DQEVENT>` ioctls

-    all return 0.
-
-    Other flags have no effect.
-
-
-Description
-===========
-
-To open a cec device applications call :c:func:`open() <cec-open>` with the
-desired device name. The function has no side effects; the device
-configuration remain unchanged.
-
-When the device is opened in read-only mode, attempts to modify its
-configuration will result in an error, and ``errno`` will be set to
-EBADF.
-
-
-Return Value
-============
-
-:c:func:`open() <cec-open>` returns the new file descriptor on success. On error,
--1 is returned, and ``errno`` is set appropriately. Possible error codes
-include:
-
-``EACCES``
-    The requested access to the file is not allowed.
-
-``EMFILE``
-    The process already has the maximum number of files open.
-
-``ENFILE``
-    The system limit on the total number of open files has been reached.
-
-``ENOMEM``
-    Insufficient kernel memory was available.
-
-``ENXIO``
-    No device corresponding to this device special file exists.

-
-
-.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )

-
-``ufds``
-   List of FD events to be watched
-
-``nfds``
-   Number of FD events at the \*ufds array
-
-``timeout``
-   Timeout to wait for events
-
-
-Description
-===========
-
-With the :c:func:`poll() <cec-poll>` function applications can wait for CEC
-events.
-
-On success :c:func:`poll() <cec-poll>` returns the number of file descriptors
-that have been selected (that is, file descriptors for which the
-``revents`` field of the respective struct :c:type:`pollfd`
-is non-zero). CEC devices set the ``POLLIN`` and ``POLLRDNORM`` flags in
-the ``revents`` field if there are messages in the receive queue. If the
-transmit queue has room for new messages, the ``POLLOUT`` and
-``POLLWRNORM`` flags are set. If there are events in the event queue,
-then the ``POLLPRI`` flag is set. When the function times out it returns
-a value of zero, on failure it returns -1 and the ``errno`` variable is
-set appropriately.
-
-For more details see the :c:func:`poll() <cec-poll>` manual page.
-
-
-Return Value
-============
-
-On success, :c:func:`poll() <cec-poll>` returns the number structures which have
-non-zero ``revents`` fields, or zero if the call timed out. On error -1
-is returned, and the ``errno`` variable is set appropriately:
-
-``EBADF``
-    One or more of the ``ufds`` members specify an invalid file
-    descriptor.
-
-``EFAULT``
-    ``ufds`` references an inaccessible memory area.
-
-``EINTR``
-    The call was interrupted by a signal.
-
-``EINVAL``
-    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
-    ``getrlimit()`` to obtain this value.

-Introduction
-============
-
-HDMI connectors provide a single pin for use by the Consumer Electronics
-Control protocol. This protocol allows different devices connected by an
-HDMI cable to communicate. The protocol for CEC version 1.4 is defined
-in supplements 1 (CEC) and 2 (HEAC or HDMI Ethernet and Audio Return
-Channel) of the HDMI 1.4a (:ref:`hdmi`) specification and the
-extensions added to CEC version 2.0 are defined in chapter 11 of the
-HDMI 2.0 (:ref:`hdmi2`) specification.
-
-The bitrate is very slow (effectively no more than 36 bytes per second)
-and is based on the ancient AV.link protocol used in old SCART
-connectors. The protocol closely resembles a crazy Rube Goldberg
-contraption and is an unholy mix of low and high level messages. Some
-messages, especially those part of the HEAC protocol layered on top of
-CEC, need to be handled by the kernel, others can be handled either by
-the kernel or by userspace.
-
-In addition, CEC can be implemented in HDMI receivers, transmitters and
-in USB devices that have an HDMI input and an HDMI output and that
-control just the CEC pin.
-
-Drivers that support CEC will create a CEC device node (/dev/cecX) to
-give userspace access to the CEC adapter. The
-:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.
-
-In order to check the support and test it, it is suggested to download
-the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ package. It
-provides three tools to handle CEC:
-
-- cec-ctl: the Swiss army knife of CEC. Allows you to configure, transmit
-  and monitor CEC messages.
-
-- cec-compliance: does a CEC compliance test of a remote CEC device to
-  determine how compliant the CEC implementation is.
-
-- cec-follower: emulates a CEC follower.

-===========
-
-All cec devices must support :ref:`ioctl CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`. To query
-device information, applications call the ioctl with a pointer to a
-struct :c:type:`cec_caps`. The driver fills the structure and
-returns the information to the application. The ioctl never fails.

-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``argp``
-    Pointer to struct :c:type:`cec_log_addrs`.
-
-Description
-===========
-
-To query the current CEC logical addresses, applications call
-:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
-struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.
-
-To set new logical addresses, applications fill in
-struct :c:type:`cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is
-returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-can only be called by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
-the ``EBUSY`` error code will be returned.
-
-To clear existing logical addresses set ``num_log_addrs`` to 0. All other fields
-will be ignored in that case. The adapter will go to the unconfigured state and the
-``cec_version``, ``vendor_id`` and ``osd_name`` fields are all reset to their default
-values (CEC version 2.0, no vendor ID and an empty OSD name).
-
-If the physical address is valid (see :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>`),
-then this ioctl will block until all requested logical
-addresses have been claimed. If the file descriptor is in non-blocking mode then it will
-not wait for the logical addresses to be claimed, instead it just returns 0.
-
-A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the
-logical addresses are claimed or cleared.
-
-Attempting to call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` when
-logical address types are already defined will return with error ``EBUSY``.

-
-    * - __u8
-      - ``log_addr[CEC_MAX_LOG_ADDRS]``
-      - The actual logical addresses that were claimed. This is set by the
-	driver. If no logical address could be claimed, then it is set to
-	``CEC_LOG_ADDR_INVALID``. If this adapter is Unregistered, then
-	``log_addr[0]`` is set to 0xf and all others to
-	``CEC_LOG_ADDR_INVALID``.
-    * - __u16
-      - ``log_addr_mask``
-      - The bitmask of all logical addresses this adapter has claimed. If
-	this adapter is Unregistered then ``log_addr_mask`` sets bit 15
-	and clears all other bits. If this adapter is not configured at
-	all, then ``log_addr_mask`` is set to 0. Set by the driver.
-    * - __u8
-      - ``cec_version``
-      - The CEC version that this adapter shall use. See
-	:ref:`cec-versions`. Used to implement the
-	``CEC_MSG_CEC_VERSION`` and ``CEC_MSG_REPORT_FEATURES`` messages.
-	Note that :ref:`CEC_OP_CEC_VERSION_1_3A <CEC-OP-CEC-VERSION-1-3A>` is not allowed by the CEC
-	framework.
-    * - __u8
-      - ``num_log_addrs``
-      - Number of logical addresses to set up. Must be ≤
-	``available_log_addrs`` as returned by
-	:ref:`CEC_ADAP_G_CAPS`. All arrays in
-	this structure are only filled up to index
-	``available_log_addrs``-1. The remaining array elements will be
-	ignored. Note that the CEC 2.0 standard allows for a maximum of 2
-	logical addresses, although some hardware has support for more.
-	``CEC_MAX_LOG_ADDRS`` is 4. The driver will return the actual
-	number of logical addresses it could claim, which may be less than
-	what was requested. If this field is set to 0, then the CEC
-	adapter shall clear all claimed logical addresses and all other
-	fields will be ignored.
-    * - __u32
-      - ``vendor_id``
-      - The vendor ID is a 24-bit number that identifies the specific
-	vendor or entity. Based on this ID vendor specific commands may be
-	defined. If you do not want a vendor ID then set it to
-	``CEC_VENDOR_ID_NONE``.
-    * - __u32
-      - ``flags``
-      - Flags. See :ref:`cec-log-addrs-flags` for a list of available flags.
-    * - char
-      - ``osd_name[15]``
-      - The On-Screen Display name as is returned by the
-	``CEC_MSG_SET_OSD_NAME`` message.
-    * - __u8
-      - ``primary_device_type[CEC_MAX_LOG_ADDRS]``
-      - Primary device type for each logical address. See
-	:ref:`cec-prim-dev-types` for possible types.
-    * - __u8
-      - ``log_addr_type[CEC_MAX_LOG_ADDRS]``
-      - Logical address types. See :ref:`cec-log-addr-types` for
-	possible types. The driver will update this with the actual
-	logical address type that it claimed (e.g. it may have to fallback
-	to :ref:`CEC_LOG_ADDR_TYPE_UNREGISTERED <CEC-LOG-ADDR-TYPE-UNREGISTERED>`).
-    * - __u8
-      - ``all_device_types[CEC_MAX_LOG_ADDRS]``
-      - CEC 2.0 specific: the bit mask of all device types. See
-	:ref:`cec-all-dev-types-flags`. It is used in the CEC 2.0
-	``CEC_MSG_REPORT_FEATURES`` message. For CEC 1.4 you can either leave
-	this field to 0, or fill it in according to the CEC 2.0 guidelines to
-	give the CEC framework more information about the device type, even
-	though the framework won't use it directly in the CEC message.
-    * - __u8
-      - ``features[CEC_MAX_LOG_ADDRS][12]``
-      - Features for each logical address. It is used in the CEC 2.0
-	``CEC_MSG_REPORT_FEATURES`` message. The 12 bytes include both the
-	RC Profile and the Device Features. For CEC 1.4 you can either leave
-        this field to all 0, or fill it in according to the CEC 2.0 guidelines to
-        give the CEC framework more information about the device type, even
-        though the framework won't use it directly in the CEC message.

-Description
-===========
-
-To query the current physical address applications call
-:ref:`ioctl CEC_ADAP_G_PHYS_ADDR <CEC_ADAP_G_PHYS_ADDR>` with a pointer to a __u16 where the
-driver stores the physical address.
-
-To set a new physical address applications store the physical address in
-a __u16 and call :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` with a pointer to
-this integer. The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` is only available if
-``CEC_CAP_PHYS_ADDR`` is set (the ``ENOTTY`` error code will be returned
-otherwise). The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can only be called
-by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
-the ``EBUSY`` error code will be returned.
-
-To clear an existing physical address use ``CEC_PHYS_ADDR_INVALID``.
-The adapter will go to the unconfigured state.
-
-If logical address types have been defined (see :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`),
-then this ioctl will block until all
-requested logical addresses have been claimed. If the file descriptor is in non-blocking mode
-then it will not wait for the logical addresses to be claimed, instead it just returns 0.
-
-A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the physical address
-changes.
-
-The physical address is a 16-bit number where each group of 4 bits
-represent a digit of the physical address a.b.c.d where the most
-significant 4 bits represent 'a'. The CEC root device (usually the TV)
-has address 0.0.0.0. Every device that is hooked up to an input of the
-TV has address a.0.0.0 (where 'a' is ≥ 1), devices hooked up to those in
-turn have addresses a.b.0.0, etc. So a topology of up to 5 devices deep
-is supported. The physical address a device shall use is stored in the
-EDID of the sink.
-
-For example, the EDID for each HDMI input of the TV will have a
-different physical address of the form a.0.0.0 that the sources will
-read out and use as their physical address.

-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-CEC_DQEVENT - Dequeue a CEC event

-.. c:function:: int ioctl( int fd, CEC_DQEVENT, struct cec_event *argp )
-    :name: CEC_DQEVENT

-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.

-
-
-Description
-===========
-
-CEC devices can send asynchronous events. These can be retrieved by
-calling :c:func:`CEC_DQEVENT`. If the file descriptor is in
-non-blocking mode and no event is pending, then it will return -1 and
-set errno to the ``EAGAIN`` error code.
-
-The internal event queues are per-filehandle and per-event type. If
-there is no more room in a queue then the last event is overwritten with
-the new one. This means that intermediate results can be thrown away but
-that the latest event is always available. This also means that is it
-possible to read two successive events that have the same value (e.g.
-two :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` events with
-the same state). In that case the intermediate state changes were lost but
-it is guaranteed that the state did change in between the two events.

-    File descriptor returned by :c:func:`open() <cec-open>`.
-

-    Pointer to CEC mode.
-
-Description
-===========
-
-By default any filehandle can use :ref:`CEC_TRANSMIT`, but in order to prevent
-applications from stepping on each others toes it must be possible to
-obtain exclusive access to the CEC adapter. This ioctl sets the
-filehandle to initiator and/or follower mode which can be exclusive
-depending on the chosen mode. The initiator is the filehandle that is
-used to initiate messages, i.e. it commands other CEC devices. The
-follower is the filehandle that receives messages sent to the CEC
-adapter and processes them. The same filehandle can be both initiator
-and follower, or this role can be taken by two different filehandles.
-
-When a CEC message is received, then the CEC framework will decide how
-it will be processed. If the message is a reply to an earlier
-transmitted message, then the reply is sent back to the filehandle that
-is waiting for it. In addition the CEC framework will process it.
-
-If the message is not a reply, then the CEC framework will process it
-first. If there is no follower, then the message is just discarded and a
-feature abort is sent back to the initiator if the framework couldn't
-process it. If there is a follower, then the message is passed on to the
-follower who will use :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` to dequeue
-the new message. The framework expects the follower to make the right
-decisions.
-
-The CEC framework will process core messages unless requested otherwise
-by the follower. The follower can enable the passthrough mode. In that
-case, the CEC framework will pass on most core messages without
-processing them and the follower will have to implement those messages.
-There are some messages that the core will always process, regardless of
-the passthrough mode. See :ref:`cec-core-processing` for details.
-
-If there is no initiator, then any CEC filehandle can use
-:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If there is an exclusive
-initiator then only that initiator can call
-:ref:`CEC_TRANSMIT`. The follower can of course
-always call :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.

-    :name: CEC_RECEIVE
-
-.. c:function:: int ioctl( int fd, CEC_TRANSMIT, struct cec_msg \*argp )
-    :name: CEC_TRANSMIT
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :c:func:`open() <cec-open>`.
-
-``argp``
-    Pointer to struct cec_msg.
-
-Description
-===========
-
-To receive a CEC message the application has to fill in the
-``timeout`` field of struct :c:type:`cec_msg` and pass it to
-:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-If the file descriptor is in non-blocking mode and there are no received
-messages pending, then it will return -1 and set errno to the ``EAGAIN``
-error code. If the file descriptor is in blocking mode and ``timeout``
-is non-zero and no message arrived within ``timeout`` milliseconds, then
-it will return -1 and set errno to the ``ETIMEDOUT`` error code.
-
-A received message can be:
-
-1. a message received from another CEC device (the ``sequence`` field will
-   be 0).
-2. the result of an earlier non-blocking transmit (the ``sequence`` field will
-   be non-zero).
-
-To send a CEC message the application has to fill in the struct
-:c:type:`cec_msg` and pass it to :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.
-The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is only available if
-``CEC_CAP_TRANSMIT`` is set. If there is no more room in the transmit
-queue, then it will return -1 and set errno to the ``EBUSY`` error code.
-The transmit queue has enough room for 18 messages (about 1 second worth
-of 2-byte messages). Note that the CEC kernel framework will also reply
-to core messages (see :ref:`cec-core-processing`), so it is not a good
-idea to fully fill up the transmit queue.
-
-If the file descriptor is in non-blocking mode then the transmit will
-return 0 and the result of the transmit will be available via
-:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` once the transmit has finished
-(including waiting for a reply, if requested).
-
-The ``sequence`` field is filled in for every transmit and this can be
-checked against the received messages to find the corresponding transmit
-result.
-
-Normally calling :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` when the physical
-address is invalid (due to e.g. a disconnect) will return ``ENONET``.
-
-However, the CEC specification allows sending messages from 'Unregistered' to
-'TV' when the physical address is invalid since some TVs pull the hotplug detect
-pin of the HDMI connector low when they go into standby, or when switching to
-another input.
-
-When the hotplug detect pin goes low the EDID disappears, and thus the
-physical address, but the cable is still connected and CEC still works.
-In order to detect/wake up the device it is allowed to send poll and 'Image/Text
-View On' messages from initiator 0xf ('Unregistered') to destination 0 ('TV').

-
-    * - __u64
-      - ``tx_ts``
-      - Timestamp in ns of when the last byte of the message was transmitted.
-	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
-	the same clock from userspace use :c:func:`clock_gettime`.
-    * - __u64
-      - ``rx_ts``
-      - Timestamp in ns of when the last byte of the message was received.
-	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
-	the same clock from userspace use :c:func:`clock_gettime`.
-    * - __u32
-      - ``len``
-      - The length of the message. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in
-	by the application. The driver will fill this in for
-	:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be
-	filled in by the driver with the length of the reply message if ``reply`` was set.
-    * - __u32
-      - ``timeout``
-      - The timeout in milliseconds. This is the time the device will wait
-	for a message to be received before timing out. If it is set to 0,
-	then it will wait indefinitely when it is called by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	If it is 0 and it is called by :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`,
-	then it will be replaced by 1000 if the ``reply`` is non-zero or
-	ignored if ``reply`` is 0.
-    * - __u32
-      - ``sequence``
-      - A non-zero sequence number is automatically assigned by the CEC framework
-	for all transmitted messages. It is used by the CEC framework when it queues
-	the transmit result (when transmit was called in non-blocking mode). This
-	allows the application to associate the received message with the original
-	transmit.
-    * - __u32
-      - ``flags``
-      - Flags. See :ref:`cec-msg-flags` for a list of available flags.
-    * - __u8
-      - ``tx_status``
-      - The status bits of the transmitted message. See
-	:ref:`cec-tx-status` for the possible status values. It is 0 if
-	this message was received, not transmitted.
-    * - __u8
-      - ``msg[16]``
-      - The message payload. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in by the
-	application. The driver will fill this in for :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be filled in by the driver with
-	the payload of the reply message if ``timeout`` was set.
-    * - __u8
-      - ``reply``
-      - Wait until this message is replied. If ``reply`` is 0 and the
-	``timeout`` is 0, then don't wait for a reply but return after
-	transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
-	The case where ``reply`` is 0 (this is the opcode for the Feature Abort
-	message) and ``timeout`` is non-zero is specifically allowed to make it
-	possible to send a message and wait up to ``timeout`` milliseconds for a
-	Feature Abort reply. In this case ``rx_status`` will either be set
-	to :ref:`CEC_RX_STATUS_TIMEOUT <CEC-RX-STATUS-TIMEOUT>` or
-	:ref:`CEC_RX_STATUS_FEATURE_ABORT <CEC-RX-STATUS-FEATURE-ABORT>`.
-
-	If the transmitter message is ``CEC_MSG_INITIATE_ARC`` then the ``reply``
-	values ``CEC_MSG_REPORT_ARC_INITIATED`` and ``CEC_MSG_REPORT_ARC_TERMINATED``
-	are processed differently: either value will match both possible replies.
-	The reason is that the ``CEC_MSG_INITIATE_ARC`` message is the only CEC
-	message that has two possible replies other than Feature Abort. The
-	``reply`` field will be updated with the actual reply so that it is
-	synchronized with the contents of the received message.
-    * - __u8
-      - ``rx_status``
-      - The status bits of the received message. See
-	:ref:`cec-rx-status` for the possible status values. It is 0 if
-	this message was transmitted, not received, unless this is the
-	reply to a transmitted message. In that case both ``rx_status``
-	and ``tx_status`` are set.
-    * - __u8
-      - ``tx_status``
-      - The status bits of the transmitted message. See
-	:ref:`cec-tx-status` for the possible status values. It is 0 if
-	this message was received, not transmitted.
-    * - __u8
-      - ``tx_arb_lost_cnt``
-      - A counter of the number of transmit attempts that resulted in the
-	Arbitration Lost error. This is only set if the hardware supports
-	this, otherwise it is always 0. This counter is only valid if the
-	:ref:`CEC_TX_STATUS_ARB_LOST <CEC-TX-STATUS-ARB-LOST>` status bit is set.
-    * - __u8
-      - ``tx_nack_cnt``
-      - A counter of the number of transmit attempts that resulted in the
-	Not Acknowledged error. This is only set if the hardware supports
-	this, otherwise it is always 0. This counter is only valid if the
-	:ref:`CEC_TX_STATUS_NACK <CEC-TX-STATUS-NACK>` status bit is set.
-    * - __u8
-      - ``tx_low_drive_cnt``
-      - A counter of the number of transmit attempts that resulted in the
-	Arbitration Lost error. This is only set if the hardware supports
-	this, otherwise it is always 0. This counter is only valid if the
-	:ref:`CEC_TX_STATUS_LOW_DRIVE <CEC-TX-STATUS-LOW-DRIVE>` status bit is set.
-    * - __u8
-      - ``tx_error_cnt``
-      - A counter of the number of transmit errors other than Arbitration
-	Lost or Not Acknowledged. This is only set if the hardware
-	supports this, otherwise it is always 0. This counter is only
-	valid if the :ref:`CEC_TX_STATUS_ERROR <CEC-TX-STATUS-ERROR>` status bit is set.

-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-The :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` can return the following
-error codes:
-
-EAGAIN
-    No messages are in the receive queue, and the filehandle is in non-blocking mode.
-
-ETIMEDOUT
-    The ``timeout`` was reached while waiting for a message.
-
-ERESTARTSYS
-    The wait for a message was interrupted (e.g. by Ctrl-C).
-
-The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` can return the following
-error codes:
-
-ENOTTY
-    The ``CEC_CAP_TRANSMIT`` capability wasn't set, so this ioctl is not supported.
-
-EPERM
-    The CEC adapter is not configured, i.e. :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-    has never been called, or ``CEC_MSG_FL_RAW`` was used from a process that
-    did not have the ``CAP_SYS_RAWIO`` capability.
-
-ENONET
-    The CEC adapter is not configured, i.e. :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
-    was called, but the physical address is invalid so no logical address was claimed.
-    An exception is made in this case for transmits from initiator 0xf ('Unregistered')
-    to destination 0 ('TV'). In that case the transmit will proceed as usual.
-
-EBUSY
-    Another filehandle is in exclusive follower or initiator mode, or the filehandle
-    is in mode ``CEC_MODE_NO_INITIATOR``. This is also returned if the transmit
-    queue is full.
-
-EINVAL
-    The contents of struct :c:type:`cec_msg` is invalid.
-
-ERESTARTSYS
-    The wait for a successful transmit was interrupted (e.g. by Ctrl-C).

-CEC Pin Framework Error Injection
-=================================
-
-The CEC Pin Framework is a core CEC framework for CEC hardware that only
-has low-level support for the CEC bus. Most hardware today will have
-high-level CEC support where the hardware deals with driving the CEC bus,
-but some older devices aren't that fancy. However, this framework also
-allows you to connect the CEC pin to a GPIO on e.g. a Raspberry Pi and
-you have now made a CEC adapter.
-
-What makes doing this so interesting is that since we have full control
-over the bus it is easy to support error injection. This is ideal to
-test how well CEC adapters can handle error conditions.
-
-Currently only the cec-gpio driver (when the CEC line is directly
-connected to a pull-up GPIO line) and the AllWinner A10/A20 drm driver
-support this framework.
-
-If ``CONFIG_CEC_PIN_ERROR_INJ`` is enabled, then error injection is available
-through debugfs. Specifically, in ``/sys/kernel/debug/cec/cecX/`` there is
-now an ``error-inj`` file.
-
-.. note::
-
-    The error injection commands are not a stable ABI and may change in the
-    future.
-
-With ``cat error-inj`` you can see both the possible commands and the current
-error injection status::
-
-	$ cat /sys/kernel/debug/cec/cec0/error-inj
-	# Clear error injections:
-	#   clear          clear all rx and tx error injections
-	#   rx-clear       clear all rx error injections
-	#   tx-clear       clear all tx error injections
-	#   <op> clear     clear all rx and tx error injections for <op>
-	#   <op> rx-clear  clear all rx error injections for <op>
-	#   <op> tx-clear  clear all tx error injections for <op>
-	#
-	# RX error injection:
-	#   <op>[,<mode>] rx-nack              NACK the message instead of sending an ACK
-	#   <op>[,<mode>] rx-low-drive <bit>   force a low-drive condition at this bit position
-	#   <op>[,<mode>] rx-add-byte          add a spurious byte to the received CEC message
-	#   <op>[,<mode>] rx-remove-byte       remove the last byte from the received CEC message
-	#   <op>[,<mode>] rx-arb-lost <poll>   generate a POLL message to trigger an arbitration lost
-	#
-	# TX error injection settings:
-	#   tx-ignore-nack-until-eom           ignore early NACKs until EOM
-	#   tx-custom-low-usecs <usecs>        define the 'low' time for the custom pulse
-	#   tx-custom-high-usecs <usecs>       define the 'high' time for the custom pulse
-	#   tx-custom-pulse                    transmit the custom pulse once the bus is idle
-	#
-	# TX error injection:
-	#   <op>[,<mode>] tx-no-eom            don't set the EOM bit
-	#   <op>[,<mode>] tx-early-eom         set the EOM bit one byte too soon
-	#   <op>[,<mode>] tx-add-bytes <num>   append <num> (1-255) spurious bytes to the message
-	#   <op>[,<mode>] tx-remove-byte       drop the last byte from the message
-	#   <op>[,<mode>] tx-short-bit <bit>   make this bit shorter than allowed
-	#   <op>[,<mode>] tx-long-bit <bit>    make this bit longer than allowed
-	#   <op>[,<mode>] tx-custom-bit <bit>  send the custom pulse instead of this bit
-	#   <op>[,<mode>] tx-short-start       send a start pulse that's too short
-	#   <op>[,<mode>] tx-long-start        send a start pulse that's too long
-	#   <op>[,<mode>] tx-custom-start      send the custom pulse instead of the start pulse
-	#   <op>[,<mode>] tx-last-bit <bit>    stop sending after this bit
-	#   <op>[,<mode>] tx-low-drive <bit>   force a low-drive condition at this bit position
-	#
-	# <op>       CEC message opcode (0-255) or 'any'
-	# <mode>     'once' (default), 'always', 'toggle' or 'off'
-	# <bit>      CEC message bit (0-159)
-	#            10 bits per 'byte': bits 0-7: data, bit 8: EOM, bit 9: ACK
-	# <poll>     CEC poll message used to test arbitration lost (0x00-0xff, default 0x0f)
-	# <usecs>    microseconds (0-10000000, default 1000)
-
-	clear
-
-You can write error injection commands to ``error-inj`` using
-``echo 'cmd' >error-inj`` or ``cat cmd.txt >error-inj``. The ``cat error-inj``
-output contains the current error commands. You can save the output to a file
-and use it as an input to ``error-inj`` later.
-
-Basic Syntax
-------------
-
-Leading spaces/tabs are ignored. If the next character is a ``#`` or the end
-of the line was reached, then the whole line is ignored. Otherwise a command
-is expected.
-
-The error injection commands fall in two main groups: those relating to
-receiving CEC messages and those relating to transmitting CEC messages. In
-addition, there are commands to clear existing error injection commands and
-to create custom pulses on the CEC bus.
-
-Most error injection commands can be executed for specific CEC opcodes or for
-all opcodes (``any``). Each command also has a 'mode' which can be ``off``
-(can be used to turn off an existing error injection command), ``once``
-(the default) which will trigger the error injection only once for the next
-received or transmitted message, ``always`` to always trigger the error
-injection and ``toggle`` to toggle the error injection on or off for every
-transmit or receive.
-
-So '``any rx-nack``' will NACK the next received CEC message,
-'``any,always rx-nack``' will NACK all received CEC messages and
-'``0x82,toggle rx-nack``' will only NACK if an Active Source message was
-received and do that only for every other received message.
-
-After an error was injected with mode ``once`` the error injection command
-is cleared automatically, so ``once`` is a one-time deal.
-
-All combinations of ``<op>`` and error injection commands can co-exist. So
-this is fine::
-
-	0x9e tx-add-bytes 1
-	0x9e tx-early-eom
-	0x9f tx-add-bytes 2
-	any rx-nack
-
-All four error injection commands will be active simultaneously.
-
-However, if the same ``<op>`` and command combination is specified,
-but with different arguments::
-
-	0x9e tx-add-bytes 1
-	0x9e tx-add-bytes 2
-
-Then the second will overwrite the first.
-
-Clear Error Injections
-----------------------
-
-``clear``
-    Clear all error injections.
-
-``rx-clear``
-    Clear all receive error injections
-
-``tx-clear``
-    Clear all transmit error injections
-
-``<op> clear``
-    Clear all error injections for the given opcode.
-
-``<op> rx-clear``
-    Clear all receive error injections for the given opcode.
-
-``<op> tx-clear``
-    Clear all transmit error injections for the given opcode.
-
-Receive Messages
-----------------
-
-``<op>[,<mode>] rx-nack``
-    NACK broadcast messages and messages directed to this CEC adapter.
-    Every byte of the message will be NACKed in case the transmitter
-    keeps transmitting after the first byte was NACKed.
-
-``<op>[,<mode>] rx-low-drive <bit>``
-    Force a Low Drive condition at this bit position. If <op> specifies
-    a specific CEC opcode then the bit position must be at least 18,
-    otherwise the opcode hasn't been received yet. This tests if the
-    transmitter can handle the Low Drive condition correctly and reports
-    the error correctly. Note that a Low Drive in the first 4 bits can also
-    be interpreted as an Arbitration Lost condition by the transmitter.
-    This is implementation dependent.
-
-``<op>[,<mode>] rx-add-byte``
-    Add a spurious 0x55 byte to the received CEC message, provided
-    the message was 15 bytes long or less. This is useful to test
-    the high-level protocol since spurious bytes should be ignored.
-
-``<op>[,<mode>] rx-remove-byte``
-    Remove the last byte from the received CEC message, provided it
-    was at least 2 bytes long. This is useful to test the high-level
-    protocol since messages that are too short should be ignored.
-
-``<op>[,<mode>] rx-arb-lost <poll>``
-    Generate a POLL message to trigger an Arbitration Lost condition.
-    This command is only allowed for ``<op>`` values of ``next`` or ``all``.
-    As soon as a start bit has been received the CEC adapter will switch
-    to transmit mode and it will transmit a POLL message. By default this is
-    0x0f, but it can also be specified explicitly via the ``<poll>`` argument.
-
-    This command can be used to test the Arbitration Lost condition in
-    the remote CEC transmitter. Arbitration happens when two CEC adapters
-    start sending a message at the same time. In that case the initiator
-    with the most leading zeroes wins and the other transmitter has to
-    stop transmitting ('Arbitration Lost'). This is very hard to test,
-    except by using this error injection command.
-
-    This does not work if the remote CEC transmitter has logical address
-    0 ('TV') since that will always win.
-
-Transmit Messages
------------------
-
-``tx-ignore-nack-until-eom``
-    This setting changes the behavior of transmitting CEC messages. Normally
-    as soon as the receiver NACKs a byte the transmit will stop, but the
-    specification also allows that the full message is transmitted and only
-    at the end will the transmitter look at the ACK bit. This is not
-    recommended behavior since there is no point in keeping the CEC bus busy
-    for longer than is strictly needed. Especially given how slow the bus is.
-
-    This setting can be used to test how well a receiver deals with
-    transmitters that ignore NACKs until the very end of the message.
-
-``<op>[,<mode>] tx-no-eom``
-    Don't set the EOM bit. Normally the last byte of the message has the EOM
-    (End-Of-Message) bit set. With this command the transmit will just stop
-    without ever sending an EOM. This can be used to test how a receiver
-    handles this case. Normally receivers have a time-out after which
-    they will go back to the Idle state.
-
-``<op>[,<mode>] tx-early-eom``
-    Set the EOM bit one byte too soon. This obviously only works for messages
-    of two bytes or more. The EOM bit will be set for the second-to-last byte
-    and not for the final byte. The receiver should ignore the last byte in
-    this case. Since the resulting message is likely to be too short for this
-    same reason the whole message is typically ignored. The receiver should be
-    in Idle state after the last byte was transmitted.
-
-``<op>[,<mode>] tx-add-bytes <num>``
-    Append ``<num>`` (1-255) spurious bytes to the message. The extra bytes
-    have the value of the byte position in the message. So if you transmit a
-    two byte message (e.g. a Get CEC Version message) and add 2 bytes, then
-    the full message received by the remote CEC adapter is
-    ``0x40 0x9f 0x02 0x03``.
-
-    This command can be used to test buffer overflows in the receiver. E.g.
-    what does it do when it receives more than the maximum message size of 16
-    bytes.
-
-``<op>[,<mode>] tx-remove-byte``
-    Drop the last byte from the message, provided the message is at least
-    two bytes long. The receiver should ignore messages that are too short.
-
-``<op>[,<mode>] tx-short-bit <bit>``
-    Make this bit period shorter than allowed. The bit position cannot be
-    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
-    must be at least 18, otherwise the opcode hasn't been received yet.
-    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
-    With this command the period of this bit is 1.8 milliseconds, this is
-    done by reducing the time the CEC bus is high. This bit period is less
-    than is allowed and the receiver should respond with a Low Drive
-    condition.
-
-    This command is ignored for 0 bits in bit positions 0 to 3. This is
-    because the receiver also looks for an Arbitration Lost condition in
-    those first four bits and it is undefined what will happen if it
-    sees a too-short 0 bit.
-
-``<op>[,<mode>] tx-long-bit <bit>``
-    Make this bit period longer than is valid. The bit position cannot be
-    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
-    must be at least 18, otherwise the opcode hasn't been received yet.
-    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
-    With this command the period of this bit is 2.9 milliseconds, this is
-    done by increasing the time the CEC bus is high.
-
-    Even though this bit period is longer than is valid it is undefined what
-    a receiver will do. It might just accept it, or it might time out and
-    return to Idle state. Unfortunately the CEC specification is silent about
-    this.
-
-    This command is ignored for 0 bits in bit positions 0 to 3. This is
-    because the receiver also looks for an Arbitration Lost condition in
-    those first four bits and it is undefined what will happen if it
-    sees a too-long 0 bit.
-
-``<op>[,<mode>] tx-short-start``
-    Make this start bit period shorter than allowed. Normally the period of
-    a start bit is between 4.3 and 4.7 milliseconds. With this command the
-    period of the start bit is 4.1 milliseconds, this is done by reducing
-    the time the CEC bus is high. This start bit period is less than is
-    allowed and the receiver should return to Idle state when this is detected.
-
-``<op>[,<mode>] tx-long-start``
-    Make this start bit period longer than is valid. Normally the period of
-    a start bit is between 4.3 and 4.7 milliseconds. With this command the
-    period of the start bit is 5 milliseconds, this is done by increasing
-    the time the CEC bus is high. This start bit period is more than is
-    valid and the receiver should return to Idle state when this is detected.
-
-    Even though this start bit period is longer than is valid it is undefined
-    what a receiver will do. It might just accept it, or it might time out and
-    return to Idle state. Unfortunately the CEC specification is silent about
-    this.
-
-``<op>[,<mode>] tx-last-bit <bit>``
-    Just stop transmitting after this bit.  If <op> specifies a specific CEC
-    opcode then the bit position must be at least 18, otherwise the opcode
-    hasn't been received yet. This command can be used to test how the receiver
-    reacts when a message just suddenly stops. It should time out and go back
-    to Idle state.
-
-``<op>[,<mode>] tx-low-drive <bit>``
-    Force a Low Drive condition at this bit position. If <op> specifies a
-    specific CEC opcode then the bit position must be at least 18, otherwise
-    the opcode hasn't been received yet. This can be used to test how the
-    receiver handles Low Drive conditions. Note that if this happens at bit
-    positions 0-3 the receiver can interpret this as an Arbitration Lost
-    condition. This is implementation dependent.
-
-Custom Pulses
--------------
-
-``tx-custom-low-usecs <usecs>``
-    This defines the duration in microseconds that the custom pulse pulls
-    the CEC line low. The default is 1000 microseconds.
-
-``tx-custom-high-usecs <usecs>``
-    This defines the duration in microseconds that the custom pulse keeps the
-    CEC line high (unless another CEC adapter pulls it low in that time).
-    The default is 1000 microseconds. The total period of the custom pulse is
-    ``tx-custom-low-usecs + tx-custom-high-usecs``.
-
-``<op>[,<mode>] tx-custom-bit <bit>``
-    Send the custom bit instead of a regular data bit. The bit position cannot
-    be an Ack bit.  If <op> specifies a specific CEC opcode then the bit
-    position must be at least 18, otherwise the opcode hasn't been received yet.
-
-``<op>[,<mode>] tx-custom-start``
-    Send the custom bit instead of a regular start bit.
-
-``tx-custom-pulse``
-    Transmit a single custom pulse as soon as the CEC bus is idle.

-put into non-blocking mode (and vice versa) using the F_SETFL command
-of the fcntl system call. This is a standard system call, documented in
-the Linux manual page for fcntl. Only one user can open the Audio Device
-in O_RDWR mode. All other attempts to open the device in this mode will
-fail, and an error code will be returned. If the Audio Device is opened
-in O_RDONLY mode, the only ioctl call that can be used is
-AUDIO_GET_STATUS. All other call will return with an error code.

-Digital TV Audio Device
-#######################
-
-The Digital TV audio device controls the MPEG2 audio decoder of the Digital
-TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
-types and and ioctl definitions can be accessed by including
-``linux/dvb/audio.h`` in your application.
-
-Please note that some Digital TV cards don’t have their own MPEG decoder, which
-results in the omission of the audio and video device.
-
-These ioctls were also used by V4L2 to control MPEG decoders implemented
-in V4L2. The use of these ioctls for that purpose has been made obsolete
-and proper V4L2 ioctls or controls have been created to replace that
-functionality.

-Audio Data Types
-****************
-
-This section describes the structures, data types and defines used when
-talking to the audio device.
-
-.. c:type:: audio_stream_source
-
-The audio stream source is set through the AUDIO_SELECT_SOURCE call
-and can take the following values, depending on whether we are replaying
-from an internal (demux) or external (user write) source.
-
-
-.. code-block:: c
-
-    typedef enum {
-	AUDIO_SOURCE_DEMUX,
-	AUDIO_SOURCE_MEMORY
-    } audio_stream_source_t;
-
-AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
-frontend or the DVR device) as the source of the video stream. If
-AUDIO_SOURCE_MEMORY is selected the stream comes from the application
-through the ``write()`` system call.
-
-
-.. c:type:: audio_play_state
-
-The following values can be returned by the AUDIO_GET_STATUS call
-representing the state of audio playback.
-
-
-.. code-block:: c
-
-    typedef enum {
-	AUDIO_STOPPED,
-	AUDIO_PLAYING,
-	AUDIO_PAUSED
-    } audio_play_state_t;
-
-
-.. c:type:: audio_channel_select
-
-The audio channel selected via AUDIO_CHANNEL_SELECT is determined by
-the following values.
-
-
-.. code-block:: c
-
-    typedef enum {
-	AUDIO_STEREO,
-	AUDIO_MONO_LEFT,
-	AUDIO_MONO_RIGHT,
-	AUDIO_MONO,
-	AUDIO_STEREO_SWAPPED
-    } audio_channel_select_t;
-
-
-.. c:type:: audio_status
-
-The AUDIO_GET_STATUS call returns the following structure informing
-about various states of the playback operation.
-
-
-.. code-block:: c
-
-    typedef struct audio_status {
-	boolean AV_sync_state;
-	boolean mute_state;
-	audio_play_state_t play_state;
-	audio_stream_source_t stream_source;
-	audio_channel_select_t channel_select;
-	boolean bypass_mode;
-	audio_mixer_t mixer_state;
-    } audio_status_t;
-
-
-.. c:type:: audio_mixer
-
-The following structure is used by the AUDIO_SET_MIXER call to set the
-audio volume.
-
-
-.. code-block:: c
-
-    typedef struct audio_mixer {
-	unsigned int volume_left;
-	unsigned int volume_right;
-    } audio_mixer_t;
-

-
-.. flat-table::
-    :header-rows:  0

-       - read-only access
-
-    -  - ``O_RDWR``
-       - read/write access
-
-    -  - ``O_NONBLOCK``
-       - open in non-blocking mode
-         (blocking mode is the default)
-
-
-Description
------------
-
-This system call opens a named ca device (e.g. ``/dev/dvb/adapter?/ca?``)
-for subsequent use.
-
-When an ``open()`` call has succeeded, the device will be ready for use. The
-significance of blocking or non-blocking mode is described in the
-documentation for functions where there is a difference. It does not
-affect the semantics of the ``open()`` call itself. A device opened in
-blocking mode can later be put into non-blocking mode (and vice versa)
-using the ``F_SETFL`` command of the ``fcntl`` system call. This is a
-standard system call, documented in the Linux manual page for fcntl.
-Only one user can open the CA Device in ``O_RDWR`` mode. All other
-attempts to open the device in this mode will fail, and an error code
-will be returned.
-
-
-Return Value
-------------
-
-
-On success 0 is returned.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.
-
-Generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-DMX_EXPBUF - Export a buffer as a DMABUF file descriptor.
-
-.. warning:: this API is still experimental
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, DMX_EXPBUF, struct dmx_exportbuffer *argp )
-    :name: DMX_EXPBUF
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``argp``
-    Pointer to struct :c:type:`dmx_exportbuffer`.
-
-
-Description
-===========
-
-This ioctl is an extension to the memory mapping I/O method.
-It can be used to export a buffer as a DMABUF file at any time after
-buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
-
-To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
-Applications must set the ``index`` field. Valid index numbers
-range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
-(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
-Additional flags may be posted in the ``flags`` field. Refer to a manual
-for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
-and O_RDWR are supported.
-All other fields must be set to zero. In the
-case of multi-planar API, every plane is exported separately using
-multiple :ref:`DMX_EXPBUF` calls.
-
-After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
-driver, on success. This is a DMABUF file descriptor. The application may
-pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
-file when it is no longer used to allow the associated memory to be reclaimed.
-
-
-Examples
-========
-
-
-.. code-block:: c
-
-    int buffer_export(int v4lfd, enum dmx_buf_type bt, int index, int *dmafd)
-    {
-	struct dmx_exportbuffer expbuf;
-
-	memset(&expbuf, 0, sizeof(expbuf));
-	expbuf.type = bt;
-	expbuf.index = index;
-	if (ioctl(v4lfd, DMX_EXPBUF, &expbuf) == -1) {
-	    perror("DMX_EXPBUF");
-	    return -1;
-	}
-
-	*dmafd = expbuf.fd;
-
-	return 0;
-    }
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    A queue is not in MMAP mode or DMABUF exporting is not supported or
-    ``flags`` or ``index`` fields are invalid.

-
-Description
------------
-
-This system call, used with a device name of ``/dev/dvb/adapter?/demux?``,
-allocates a new filter and returns a handle which can be used for
-subsequent control of that filter. This call has to be made for each
-filter to be used, i.e. every returned file descriptor is a reference to
-a single filter. ``/dev/dvb/adapter?/dvr?`` is a logical device to be used
-for retrieving Transport Streams for digital video recording. When
-reading from this device a transport stream containing the packets from
-all PES filters set in the corresponding demux device
-(``/dev/dvb/adapter?/demux?``) having the output set to ``DMX_OUT_TS_TAP``.
-A recorded Transport Stream is replayed by writing to this device.
-
-The significance of blocking or non-blocking mode is described in the
-documentation for functions where there is a difference. It does not
-affect the semantics of the ``open()`` call itself. A device opened
-in blocking mode can later be put into non-blocking mode (and vice versa)
-using the ``F_SETFL`` command of the fcntl system call.
-
-
-Return Value
-------------
-
-On success 0 is returned.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.

------------
-
-This ioctl call returns the current value of the system time counter
-(which is driven by a PES filter of type :c:type:`DMX_PES_PCR <dmx_ts_pes>`).
-Some hardware supports more than one STC, so you must specify which one by
-setting the :c:type:`num <dmx_stc>` field of stc before the ioctl (range 0...n).
-The result is returned in form of a ratio with a 64 bit numerator
-and a 32 bit denominator, so the real 90kHz STC value is
-``stc->stc / stc->base``.
-
-
-Return Value

-dmx-mmap - Map device memory into application address space
-
-.. warning:: this API is still experimental
-
-Synopsis
-========
-
-.. code-block:: c
-
-    #include <unistd.h>
-    #include <sys/mman.h>
-
-
-.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
-    :name: dmx-mmap
-
-Arguments
-=========
-
-``start``
-    Map the buffer to this address in the application's address space.
-    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
-    multiple of the pagesize and mmap will fail when the specified
-    address cannot be used. Use of this option is discouraged;
-    applications should just specify a ``NULL`` pointer here.
-
-``length``
-    Length of the memory area to map. This must be a multiple of the
-    DVB packet length (188, on most drivers).
-
-``prot``
-    The ``prot`` argument describes the desired memory protection.
-    Regardless of the device type and the direction of data exchange it
-    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
-    and write access to image buffers. Drivers should support at least
-    this combination of flags.
-
-``flags``
-    The ``flags`` parameter specifies the type of the mapped object,
-    mapping options and whether modifications made to the mapped copy of
-    the page are private to the process or are to be shared with other
-    references.
-
-    ``MAP_FIXED`` requests that the driver selects no other address than
-    the one specified. If the specified address cannot be used,
-    :ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
-    ``start`` must be a multiple of the pagesize. Use of this option is
-    discouraged.
-
-    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
-    ``MAP_SHARED`` allows applications to share the mapped memory with
-    other (e. g. child-) processes.
-
-    .. note::
-
-       The Linux Digital TV applications should not set the
-       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
-       flags.
-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``offset``
-    Offset of the buffer in device memory, as returned by
-    :ref:`DMX_QUERYBUF` ioctl.
-
-
-Description
-===========
-
-The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
-``offset`` in the memory of the device specified by ``fd`` into the
-application address space, preferably at address ``start``. This latter
-address is a hint only, and is usually specified as 0.
-
-Suitable length and offset parameters are queried with the
-:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
-:ref:`DMX_REQBUFS` ioctl before they can be queried.
-
-To unmap buffers the :ref:`munmap() <dmx-munmap>` function is used.
-
-
-Return Value
-============
-
-On success :ref:`mmap() <dmx-mmap>` returns a pointer to the mapped buffer. On
-error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
-appropriately. Possible error codes are:
-
-EBADF
-    ``fd`` is not a valid file descriptor.
-
-EACCES
-    ``fd`` is not open for reading and writing.
-
-EINVAL
-    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
-    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
-
-    The ``flags`` or ``prot`` value is not supported.
-
-    No buffers have been allocated with the
-    :ref:`DMX_REQBUFS` ioctl.
-
-ENOMEM
-    Not enough physical or virtual memory was available to complete the
-    request.

-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``argp``
-    Pointer to struct :c:type:`dmx_buffer`.
-
-
-Description
-===========
-
-Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
-(capturing) or filled (output) buffer in the driver's incoming queue.
-The semantics depend on the selected I/O method.
-
-To enqueue a buffer applications set the ``index`` field. Valid index
-numbers range from zero to the number of buffers allocated with
-:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
-one. The contents of the struct :c:type:`dmx_buffer` returned
-by a :ref:`DMX_QUERYBUF` ioctl will do as well.
-
-When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
-memory pages of the buffer in physical memory, so they cannot be swapped
-out to disk. Buffers remain locked until dequeued, until the
-the device is closed.
-
-Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
-(capturing) buffer from the driver's outgoing queue.
-They just set the ``index`` field with the buffer ID to be queued.
-When ``DMX_DQBUF`` is called with a pointer to struct :c:type:`dmx_buffer`,
-the driver fills the remaining fields or returns an error code.
-
-By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
-queue. When the ``O_NONBLOCK`` flag was given to the
-:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
-immediately with an ``EAGAIN`` error code when no buffer is available.
-
-The struct :c:type:`dmx_buffer` structure is specified in
-:ref:`buffer`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EAGAIN
-    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
-    buffer was in the outgoing queue.
-
-EINVAL
-    The ``index`` is out of bounds, or no buffers have been allocated yet.
-
-EIO
-    ``DMX_DQBUF`` failed due to an internal error. Can also indicate
-    temporary problems like signal loss or CRC errors.

-    File descriptor returned by :ref:`open() <dmx_fopen>`.
-
-``argp``
-    Pointer to struct :c:type:`dmx_requestbuffers`.
-
-Description
-===========
-
-This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
-
-Memory mapped buffers are located in device memory and must be allocated
-with this ioctl before they can be mapped into the application's address
-space. User buffers are allocated by applications themselves, and this
-ioctl is merely used to switch the driver into user pointer I/O mode and
-to setup some internal structures. Similarly, DMABUF buffers are
-allocated by applications through a device driver, and this ioctl only
-configures the driver into DMABUF I/O mode without performing any direct
-allocation.
-
-To allocate device buffers applications initialize all fields of the
-struct :c:type:`dmx_requestbuffers` structure. They set the  ``count`` field
-to the desired number of buffers,  and ``size`` to the size of each
-buffer.
-
-When the ioctl is called with a pointer to this structure, the driver will
-attempt to allocate the requested number of buffers and it stores the actual
-number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
-number is also possible when the driver requires more buffers to
-function correctly. The actual allocated buffer size can is returned
-at ``size``, and can be smaller than what's requested.
-
-When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
-error code.
-
-Applications can call :ref:`DMX_REQBUFS` again to change the number of
-buffers, however this cannot succeed when any buffers are still mapped.
-A ``count`` value of zero frees all buffers, after aborting or finishing
-any DMA in progress.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EOPNOTSUPP
-    The  the requested I/O method is not supported.

-state whether a section should be CRC-checked, whether the filter should
-be a ”one-shot” filter, i.e. if the filtering operation should be
-stopped after the first section is received, and whether the filtering
-operation should be started immediately (without waiting for a

-*******************
-frontend parameters
-*******************
-
-The kind of parameters passed to the frontend device for tuning depend
-on the kind of hardware you are using.
-
-The struct ``dvb_frontend_parameters`` uses a union with specific
-per-system parameters. However, as newer delivery systems required more
-data, the structure size weren't enough to fit, and just extending its
-size would break the existing applications. So, those parameters were
-replaced by the usage of
-:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
-ioctl's. The new API is flexible enough to add new parameters to
-existing delivery systems, and to add newer delivery systems.
-
-So, newer applications should use
-:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
-instead, in order to be able to support the newer System Delivery like
-DVB-S2, DVB-T2, DVB-C2, ISDB, etc.
-
-All kinds of parameters are combined as a union in the
-``dvb_frontend_parameters`` structure:
-
-
-.. code-block:: c
-
-    struct dvb_frontend_parameters {
-	uint32_t frequency;     /* (absolute) frequency in Hz for QAM/OFDM */
-		    /* intermediate frequency in kHz for QPSK */
-	fe_spectral_inversion_t inversion;
-	union {
-	    struct dvb_qpsk_parameters qpsk;
-	    struct dvb_qam_parameters  qam;
-	    struct dvb_ofdm_parameters ofdm;
-	    struct dvb_vsb_parameters  vsb;
-	} u;
-    };
-
-In the case of QPSK frontends the ``frequency`` field specifies the
-intermediate frequency, i.e. the offset which is effectively added to
-the local oscillator frequency (LOF) of the LNB. The intermediate
-frequency has to be specified in units of kHz. For QAM and OFDM
-frontends the ``frequency`` specifies the absolute frequency and is
-given in Hz.
-
-
-.. c:type:: dvb_qpsk_parameters
-
-QPSK parameters
-===============
-
-For satellite QPSK frontends you have to use the ``dvb_qpsk_parameters``
-structure:
-
-
-.. code-block:: c
-
-     struct dvb_qpsk_parameters {
-	 uint32_t        symbol_rate;  /* symbol rate in Symbols per second */
-	 fe_code_rate_t  fec_inner;    /* forward error correction (see above) */
-     };
-
-
-.. c:type:: dvb_qam_parameters
-
-QAM parameters
-==============
-
-for cable QAM frontend you use the ``dvb_qam_parameters`` structure:
-
-
-.. code-block:: c
-
-     struct dvb_qam_parameters {
-	 uint32_t         symbol_rate; /* symbol rate in Symbols per second */
-	 fe_code_rate_t   fec_inner;   /* forward error correction (see above) */
-	 fe_modulation_t  modulation;  /* modulation type (see above) */
-     };
-
-
-.. c:type:: dvb_vsb_parameters
-
-VSB parameters
-==============
-
-ATSC frontends are supported by the ``dvb_vsb_parameters`` structure:
-
-
-.. code-block:: c
-
-    struct dvb_vsb_parameters {
-	fe_modulation_t modulation; /* modulation type (see above) */
-    };
-
-

-===============
-
-DVB-T frontends are supported by the ``dvb_ofdm_parameters`` structure:
-
-
-.. code-block:: c
-
-     struct dvb_ofdm_parameters {
-	 fe_bandwidth_t      bandwidth;
-	 fe_code_rate_t      code_rate_HP;  /* high priority stream code rate */

-
-Tuning into a Digital TV physical channel and starting decoding it
-requires changing a set of parameters, in order to control the tuner,
-the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
-antenna subsystem via Satellite Equipment Control - SEC (on satellite
-systems). The actual parameters are specific to each particular digital
-TV standards, and may change as the digital TV specs evolves.
-
-In the past (up to DVB API version 3 - DVBv3), the strategy used was to have a
-union with the parameters needed to tune for DVB-S, DVB-C, DVB-T and
-ATSC delivery systems grouped there. The problem is that, as the second
-generation standards appeared, the size of such union was not big
-enough to group the structs that would be required for those new
-standards. Also, extending it would break userspace.
-
-So, the legacy union/struct based approach was deprecated, in favor
-of a properties set approach. On such approach,
-:ref:`FE_GET_PROPERTY and FE_SET_PROPERTY <FE_GET_PROPERTY>` are used
-to setup the frontend and read its status.
-
-The actual action is determined by a set of dtv_property cmd/data pairs.
-With one single ioctl, is possible to get/set up to 64 properties.
-
-This section describes the new and recommended way to set the frontend,
-with supports all digital TV delivery systems.
-
-.. note::
-
-   1. On Linux DVB API version 3, setting a frontend was done via
-      struct :c:type:`dvb_frontend_parameters`.
-
-   2. Don't use DVB API version 3 calls on hardware with supports
-      newer standards. Such API provides no support or a very limited
-      support to new standards and/or new hardware.
-
-   3. Nowadays, most frontends support multiple delivery systems.
-      Only with DVB API version 5 calls it is possible to switch between
-      the multiple delivery systems supported by a frontend.
-
-   4. DVB API version 5 is also called *S2API*, as the first
-      new standard added to it was DVB-S2.
-
-**Example**: in order to set the hardware to tune into a DVB-C channel
-at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol rate of 5.217
-Mbauds, those properties should be sent to
-:ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` ioctl:
-

-ATSC (version 1)	No need to set. It is always 6MHz.
-DMTB			No need to set. It is always 8MHz.
-DVB-T			6MHz, 7MHz and 8MHz.
-DVB-T2			1.172 MHz, 5MHz, 6MHz, 7MHz, 8MHz and 10MHz
-ISDB-T			5MHz, 6MHz, 7MHz and 8MHz, although most places
-			use 6MHz.
-======================= =======================================================
-
-
-.. note::
-
-
-  #. For ISDB-Tsb, the bandwidth can vary depending on the number of
-     connected segments.
-
-     It can be easily derived from other parameters
-     (DTV_ISDBT_SB_SEGMENT_IDX, DTV_ISDBT_SB_SEGMENT_COUNT).
-
-  #. On Satellite and Cable delivery systems, the bandwidth depends on
-     the symbol rate. So, the Kernel will silently ignore any setting
-     :ref:`DTV-BANDWIDTH-HZ`. I will however fill it back with a
-     bandwidth estimation.
-
-     Such bandwidth estimation takes into account the symbol rate set with
-     :ref:`DTV-SYMBOL-RATE`, and the rolloff factor, with is fixed for
-     DVB-C and DVB-S.
-
-     For DVB-S2, the rolloff should also be set via :ref:`DTV-ROLLOFF`.

-
-
-.. _DTV-ISDBT-SB-SUBCHANNEL-ID:
-
-DTV_ISDBT_SB_SUBCHANNEL_ID
-==========================
-
-Used only on ISDB.
-
-This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
-
-(Note of the author: This might not be the correct description of the
-``SUBCHANNEL-ID`` in all details, but it is my understanding of the
-technical background needed to program a device)
-
-An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a
-set of connected ISDB-Tsb channels. In this set of channels every
-channel can be received independently. The number of connected ISDB-Tsb
-segment can vary, e.g. depending on the frequency spectrum bandwidth
-available.
-
-Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
-broadcaster has several possibilities to put those channels in the air:
-Assuming a normal 13-segment ISDB-T spectrum he can align the 8 segments
-from position 1-8 to 5-13 or anything in between.
-
-The underlying layer of segments are subchannels: each segment is
-consisting of several subchannels with a predefined IDs. A sub-channel
-is used to help the demodulator to synchronize on the channel.
-
-An ISDB-T channel is always centered over all sub-channels. As for the
-example above, in ISDB-Tsb it is no longer as simple as that.
-
-``The DTV_ISDBT_SB_SUBCHANNEL_ID`` parameter is used to give the
-sub-channel ID of the segment to be demodulated.
-
-Possible values: 0 .. 41, -1 (AUTO)
-
-
-.. _DTV-ISDBT-SB-SEGMENT-IDX:
-
-DTV_ISDBT_SB_SEGMENT_IDX
-========================
-
-Used only on ISDB.
-
-This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
-
-``DTV_ISDBT_SB_SEGMENT_IDX`` gives the index of the segment to be
-demodulated for an ISDB-Tsb channel where several of them are
-transmitted in the connected manner.
-
-Possible values: 0 .. ``DTV_ISDBT_SB_SEGMENT_COUNT`` - 1
-
-Note: This value cannot be determined by an automatic channel search.
-
-
-.. _DTV-ISDBT-SB-SEGMENT-COUNT:
-
-DTV_ISDBT_SB_SEGMENT_COUNT
-==========================
-
-Used only on ISDB.
-
-This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
-
-``DTV_ISDBT_SB_SEGMENT_COUNT`` gives the total count of connected
-ISDB-Tsb channels.
-
-Possible values: 1 .. 13
-
-Note: This value cannot be determined by an automatic channel search.
-
-
-.. _isdb-hierq-layers:
-
-DTV-ISDBT-LAYER[A-C] parameters
-===============================
-
-Used only on ISDB.
-
-ISDB-T channels can be coded hierarchically. As opposed to DVB-T in
-ISDB-T hierarchical layers can be decoded simultaneously. For that
-reason a ISDB-T demodulator has 3 Viterbi and 3 Reed-Solomon decoders.
-
-ISDB-T has 3 hierarchical layers which each can use a part of the
-available segments. The total number of segments over all layers has to
-13 in ISDB-T.
-
-There are 3 parameter sets, for Layers A, B and C.
-
-
-.. _DTV-ISDBT-LAYER-ENABLED:
-
-DTV_ISDBT_LAYER_ENABLED
------------------------
-
-Used only on ISDB.
-
-Hierarchical reception in ISDB-T is achieved by enabling or disabling
-layers in the decoding process. Setting all bits of
-``DTV_ISDBT_LAYER_ENABLED`` to '1' forces all layers (if applicable) to
-be demodulated. This is the default.
-
-If the channel is in the partial reception mode
-(``DTV_ISDBT_PARTIAL_RECEPTION`` = 1) the central segment can be decoded
-independently of the other 12 segments. In that mode layer A has to have
-a ``SEGMENT_COUNT`` of 1.
-
-In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb according
-to ``DTV_ISDBT_PARTIAL_RECEPTION``. ``SEGMENT_COUNT`` must be filled
-accordingly.
-
-Only the values of the first 3 bits are used. Other bits will be silently ignored:
-
-``DTV_ISDBT_LAYER_ENABLED`` bit 0: layer A enabled
-
-``DTV_ISDBT_LAYER_ENABLED`` bit 1: layer B enabled
-
-``DTV_ISDBT_LAYER_ENABLED`` bit 2: layer C enabled
-
-``DTV_ISDBT_LAYER_ENABLED`` bits 3-31: unused

-
-.. note::
-
-   #. If layer C is ``DQPSK``, then layer B has to be ``DQPSK``.
-
-   #. If layer B is ``DQPSK`` and ``DTV_ISDBT_PARTIAL_RECEPTION``\ = 0,
-      then layer has to be ``DQPSK``.

-
-DVB-S2, DVB-T2 and ISDB-S support the transmission of several streams on
-a single transport stream. This property enables the digital TV driver to
-handle substream filtering, when supported by the hardware. By default,
-substream filtering is disabled.
-
-For DVB-S2 and DVB-T2, the valid substream id range is from 0 to 255.
-
-For ISDB, the valid substream id range is from 1 to 65535.
-
-To disable it, you should use the special macro NO_STREAM_ID_FILTER.

-
-A Multi standard frontend needs to advertise the delivery systems

-introduction, FE_GET_INFO was used to determine a frontend type. A
-frontend which provides more than a single delivery system,
-FE_GET_INFO doesn't help much. Applications which intends to use a
-multistandard frontend must enumerate the delivery systems associated
-with it, rather than trying to use FE_GET_INFO. In the case of a
-legacy frontend, the result is just the same as with FE_GET_INFO, but
-in a more structured format

-
-.. _DTV-LNA:
-
-DTV_LNA
-=======
-
-Low-noise amplifier.
-
-Hardware might offer controllable LNA which can be set manually using
-that parameter. Usually LNA could be found only from terrestrial devices
-if at all.
-
-Possible values: 0, 1, LNA_AUTO
-
-0, LNA off
-
-1, LNA on
-
-use the special macro LNA_AUTO to set LNA auto

-
-.. _DTV-SCRAMBLING-SEQUENCE-INDEX:
-
-DTV_SCRAMBLING_SEQUENCE_INDEX
-=============================
-
-Used on DVB-S2.
-
-This 18 bit field, when present, carries the index of the DVB-S2 physical
-layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
-There is no explicit signalling method to convey scrambling sequence index
-to the receiver. If S2 satellite delivery system descriptor is available
-it can be used to read the scrambling sequence index (EN 300 468 table 41).
-
-By default, gold scrambling sequence index 0 is used.
-
-The valid scrambling sequence index range is from 0 to 262142.

-ISDB-T delivery system
-======================
-
-This ISDB-T/ISDB-Tsb API extension should reflect all information needed
-to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
-very sophisticated devices won't need certain parameters to tune.
-
-The information given here should help application writers to know how
-to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API.
-
-The details given here about ISDB-T and ISDB-Tsb are just enough to
-basically show the dependencies between the needed parameter values, but
-surely some information is left out. For more detailed information see
-the following documents:
-
-ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
-Broadcasting" and
-
-ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
-Broadcasting".
-
-In order to understand the ISDB specific parameters, one has to have
-some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
-to be known to the reader that an ISDB-T channel consists of 13
-segments, that it can have up to 3 layer sharing those segments, and
-things like that.

-
-******************************
-Frontend statistics indicators
-******************************
-
-The values are returned via ``dtv_property.stat``. If the property is
-supported, ``dtv_property.stat.len`` is bigger than zero.
-
-For most delivery systems, ``dtv_property.stat.len`` will be 1 if the
-stats is supported, and the properties will return a single value for
-each parameter.
-
-It should be noted, however, that new OFDM delivery systems like ISDB
-can use different modulation types for each group of carriers. On such
-standards, up to 3 groups of statistics can be provided, and
-``dtv_property.stat.len`` is updated to reflect the "global" metrics,
-plus one metric per each carrier group (called "layer" on ISDB).
-
-So, in order to be consistent with other delivery systems, the first
-value at :c:type:`dtv_property.stat.dtv_stats <dtv_stats>` array refers
-to the global metric. The other elements of the array represent each
-layer, starting from layer A(index 1), layer B (index 2) and so on.
-
-The number of filled elements are stored at ``dtv_property.stat.len``.
-
-Each element of the ``dtv_property.stat.dtv_stats`` array consists on
-two elements:
-
--  ``svalue`` or ``uvalue``, where ``svalue`` is for signed values of
-   the measure (dB measures) and ``uvalue`` is for unsigned values
-   (counters, relative scale)
-
--  ``scale`` - Scale for the value. It can be:
-
-   -  ``FE_SCALE_NOT_AVAILABLE`` - The parameter is supported by the
-      frontend, but it was not possible to collect it (could be a
-      transitory or permanent condition)
-
-   -  ``FE_SCALE_DECIBEL`` - parameter is a signed value, measured in
-      1/1000 dB
-
-   -  ``FE_SCALE_RELATIVE`` - parameter is a unsigned value, where 0
-      means 0% and 65535 means 100%.
-
-   -  ``FE_SCALE_COUNTER`` - parameter is a unsigned value that counts
-      the occurrence of an event, like bit error, block error, or lapsed
-      time.
-
-
-.. _DTV-STAT-SIGNAL-STRENGTH:
-
-DTV_STAT_SIGNAL_STRENGTH
-========================
-
-Indicates the signal strength level at the analog part of the tuner or
-of the demod.
-
-Possible scales for this metric are:
-
--  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
-   measurement was not complete yet.
-
--  ``FE_SCALE_DECIBEL`` - signal strength is in 0.001 dBm units, power
-   measured in miliwatts. This value is generally negative.
-
--  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
-   measurement for power (actually, 0 to 65535).
-
-
-.. _DTV-STAT-CNR:
-
-DTV_STAT_CNR
-============
-
-Indicates the Signal to Noise ratio for the main carrier.
-
-Possible scales for this metric are:
-
--  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
-   measurement was not complete yet.
-
--  ``FE_SCALE_DECIBEL`` - Signal/Noise ratio is in 0.001 dB units.
-
--  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
-   measurement for Signal/Noise (actually, 0 to 65535).

-Digital TV Frontend API
-#######################
-
-The Digital TV frontend API was designed to support three groups of delivery
-systems: Terrestrial, cable and Satellite. Currently, the following
-delivery systems are supported:
-
--  Terrestrial systems: DVB-T, DVB-T2, ATSC, ATSC M/H, ISDB-T, DVB-H,
-   DTMB, CMMB
-
--  Cable systems: DVB-C Annex A/C, ClearQAM (DVB-C Annex B)
-
--  Satellite systems: DVB-S, DVB-S2, DVB Turbo, ISDB-S, DSS
-
-The Digital TV frontend controls several sub-devices including:
-
--  Tuner
-
--  Digital TV demodulator
-
--  Low noise amplifier (LNA)
-
--  Satellite Equipment Control (SEC) [#f1]_.
-
-The frontend can be accessed through ``/dev/dvb/adapter?/frontend?``.
-Data types and ioctl definitions can be accessed by including
-``linux/dvb/frontend.h`` in your application.
-
-.. note::
-
-   Transmission via the internet (DVB-IP) and MMT (MPEG Media Transport)
-   is not yet handled by this API but a future extension is possible.
-
-.. [#f1]
-
-   On Satellite systems, the API support for the Satellite Equipment
-   Control (SEC) allows to power control and to send/receive signals to
-   control the antenna subsystem, selecting the polarization and choosing
-   the Intermediate Frequency IF) of the Low Noise Block Converter Feed
-   Horn (LNBf). It supports the DiSEqC and V-SEC protocols. The DiSEqC
-   (digital SEC) specification is available at

-
-
-Description
-===========
-
-This system call opens a named frontend device
-(``/dev/dvb/adapter?/frontend?``) for subsequent use. Usually the first
-thing to do after a successful open is to find out the frontend type
-with :ref:`FE_GET_INFO`.
-
-The device can be opened in read-only mode, which only allows monitoring
-of device status and statistics, or read/write mode, which allows any
-kind of use (e.g. performing tuning operations.)
-
-In a system with multiple front-ends, it is usually the case that
-multiple devices cannot be open in read/write mode simultaneously. As
-long as a front-end device is opened in read/write mode, other open()
-calls in read/write mode will either fail or block, depending on whether
-non-blocking or blocking mode was specified. A front-end device opened
-in blocking mode can later be put into non-blocking mode (and vice
-versa) using the F_SETFL command of the fcntl system call. This is a
-standard system call, documented in the Linux manual page for fcntl.
-When an open() call has succeeded, the device will be ready for use in
-the specified mode. This implies that the corresponding hardware is
-powered up, and that other front-ends may have been powered down to make
-that possible.
-
-
-Return Value
-============
-
-On success :ref:`open() <frontend_f_open>` returns the new file descriptor.
-On error, -1 is returned, and the ``errno`` variable is set appropriately.
-
-Possible error codes are:
-
-
-On success 0 is returned, and :c:type:`ca_slot_info` is filled.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.

-
-What you need to know
-=====================
-
-The reader of this document is required to have some knowledge in the
-area of digital video broadcasting (Digital TV) and should be familiar with
-part I of the MPEG2 specification ISO/IEC 13818 (aka ITU-T H.222), i.e
-you should know what a program/transport stream (PS/TS) is and what is
-meant by a packetized elementary stream (PES) or an I-frame.
-
-Various Digital TV standards documents are available for download at:
-
-- European standards (DVB): http://www.dvb.org and/or http://www.etsi.org.
-- American standards (ATSC): https://www.atsc.org/standards/
-- Japanese standards (ISDB): http://www.dibeg.org/
-
-It is also necessary to know how to access Linux devices and how to
-use ioctl calls. This also includes the knowledge of C or C++.
-
-
-.. _history:
-
-History
-=======
-
-The first API for Digital TV cards we used at Convergence in late 1999 was an
-extension of the Video4Linux API which was primarily developed for frame
-grabber cards. As such it was not really well suited to be used for Digital
-TV cards and their new features like recording MPEG streams and filtering
-several section and PES data streams at the same time.
-
-In early 2000, Convergence was approached by Nokia with a proposal for a new
-standard Linux Digital TV API. As a commitment to the development of terminals
-based on open standards, Nokia and Convergence made it available to all
-Linux developers and published it on https://linuxtv.org in September
-2000. With the Linux driver for the Siemens/Hauppauge DVB PCI card,
-Convergence provided a first implementation of the Linux Digital TV API.
-Convergence was the maintainer of the Linux Digital TV API in the early
-days.
-
-Now, the API is maintained by the LinuxTV community (i.e. you, the reader
-of this document). The Linux  Digital TV API is constantly reviewed and
-improved together with the improvements at the subsystem's core at the
-Kernel.

-    :align: center
-
-    Components of a Digital TV card/STB
-
-A Digital TV card or set-top-box (STB) usually consists of the
-following main hardware components:
-
-Frontend consisting of tuner and digital TV demodulator
-   Here the raw signal reaches the digital TV hardware from a satellite dish or
-   antenna or directly from cable. The frontend down-converts and
-   demodulates this signal into an MPEG transport stream (TS). In case
-   of a satellite frontend, this includes a facility for satellite
-   equipment control (SEC), which allows control of LNB polarization,
-   multi feed switches or dish rotors.
-
-Conditional Access (CA) hardware like CI adapters and smartcard slots
-   The complete TS is passed through the CA hardware. Programs to which
-   the user has access (controlled by the smart card) are decoded in
-   real time and re-inserted into the TS.
-
-   .. note::
-
-      Not every digital TV hardware provides conditional access hardware.
-
-Demultiplexer which filters the incoming Digital TV MPEG-TS stream
-   The demultiplexer splits the TS into its components like audio and
-   video streams. Besides usually several of such audio and video
-   streams it also contains data streams with information about the
-   programs offered in this or other streams of the same provider.
-
-Audio and video decoder
-   The main targets of the demultiplexer are audio and video
-   decoders. After decoding, they pass on the uncompressed audio and
-   video to the computer screen or to a TV set.
-
-   .. note::
-
-      Modern hardware usually doesn't have a separate decoder hardware, as
-      such functionality can be provided by the main CPU, by the graphics
-      adapter of the system or by a signal processing hardware embedded on
-      a Systems on a Chip (SoC) integrated circuit.
-
-      It may also not be needed for certain usages (e.g. for data-only
-      uses like “internet over satellite”).
-
-:ref:`stb_components` shows a crude schematic of the control and data
-flow between those components.

-
-Linux Digital TV Devices
-========================
-
-The Linux Digital TV API lets you control these hardware components through
-currently six Unix-style character devices for video, audio, frontend,
-demux, CA and IP-over-DVB networking. The video and audio devices
-control the MPEG2 decoder hardware, the frontend device the tuner and
-the Digital TV demodulator. The demux device gives you control over the PES
-and section filters of the hardware. If the hardware does not support
-filtering these filters can be implemented in software. Finally, the CA
-device controls all the conditional access capabilities of the hardware.
-It can depend on the individual security requirements of the platform,
-if and how many of the CA functions are made available to the
-application through this device.
-
-All devices can be found in the ``/dev`` tree under ``/dev/dvb``. The

-API include files
-=================
-
-For each of the Digital TV devices a corresponding include file exists. The
-Digital TV API include files should be included in application sources with a
-partial path like:
-
-
-.. code-block:: c
-
-	#include <linux/dvb/ca.h>
-
-	#include <linux/dvb/dmx.h>
-
-	#include <linux/dvb/frontend.h>
-
-	#include <linux/dvb/net.h>
-
-
-To enable applications to support different API version, an additional
-include file ``linux/dvb/version.h`` exists, which defines the constant
-``DVB_API_VERSION``. This document describes ``DVB_API_VERSION 5.10``.

-
-Return Value
-============
-
-On success 0 is returned, and :c:type:`ca_slot_info` is filled.
-
-On error -1 is returned, and the ``errno`` variable is set
-appropriately.

-Digital TV Network API
-######################
-
-The Digital TV net device controls the mapping of data packages that are part
-of a transport stream to be mapped into a virtual network interface,
-visible through the standard Linux network protocol stack.
-
-Currently, two encapsulations are supported:
-
--  `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
-
--  `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
-
-In order to create the Linux virtual network interfaces, an application
-needs to tell to the Kernel what are the PIDs and the encapsulation
-types that are present on the transport stream. This is done through
-``/dev/dvb/adapter?/net?`` device node. The data will be available via
-virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
-the standard ip tools (like ip, route, netstat, ifconfig, etc).
-
-Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
-header.

-Description
------------
-
-This system call opens a named video device (e.g.
-/dev/dvb/adapter0/video0) for subsequent use.
-
-When an open() call has succeeded, the device will be ready for use. The
-significance of blocking or non-blocking mode is described in the
-documentation for functions where there is a difference. It does not
-affect the semantics of the open() call itself. A device opened in
-blocking mode can later be put into non-blocking mode (and vice versa)
-using the F_SETFL command of the fcntl system call. This is a standard
-system call, documented in the Linux manual page for fcntl. Only one
-user can open the Video Device in O_RDWR mode. All other attempts to
-open the device in this mode will fail, and an error-code will be
-returned. If the Video Device is opened in O_RDONLY mode, the only
-ioctl call that can be used is VIDEO_GET_STATUS. All other call will
-return an error code.

-Description
------------
-
-This ioctl is for Digital TV devices only. To control a V4L2 decoder use the
-V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
-
-This ioctl call suspends the live video stream being played. Decoding
-and playing are frozen. It is then possible to restart the decoding and
-playing process of the video stream using the VIDEO_CONTINUE command.
-If VIDEO_SOURCE_MEMORY is selected in the ioctl call
-VIDEO_SELECT_SOURCE, the Digital TV subsystem will not decode any more data
-until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.
-
-
-Return Value
-------------
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-Description
------------
-
-This ioctl is for Digital TV devices only. To get events from a V4L2 decoder
-use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
-
-This ioctl call returns an event of type video_event if available. If
-an event is not available, the behavior depends on whether the device is
-in blocking or non-blocking mode. In the latter case, the call fails
-immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
-blocks until an event becomes available. The standard Linux poll()
-and/or select() system calls can be used with the device file descriptor
-to watch for new events. For select(), the file descriptor should be
-included in the exceptfds argument, and for poll(), POLLPRI should be
-specified as the wake-up condition. Read-only permissions are sufficient
-for this ioctl call.

-:ref:`VIDIOC_TRY_DECODER_CMD <VIDIOC_DECODER_CMD>` ioctl.
-
-This ioctl tries a decoder command. The ``video_command`` struct is a
-subset of the ``v4l2_decoder_cmd`` struct, so refer to the
-:ref:`VIDIOC_TRY_DECODER_CMD <VIDIOC_DECODER_CMD>` documentation
-for more information.
-
-
-Return Value
-------------
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-Digital TV Video Device
-#######################
-
-The Digital TV video device controls the MPEG2 video decoder of the Digital
-TV hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
-types and and ioctl definitions can be accessed by including
-**linux/dvb/video.h** in your application.
-
-Note that the Digital TV video device only controls decoding of the MPEG video
-stream, not its presentation on the TV or computer screen. On PCs this
-is typically handled by an associated video4linux device, e.g.
-**/dev/video**, which allows scaling and defining output windows.
-
-Some Digital TV cards don’t have their own MPEG decoder, which results in the
-omission of the audio and video device as well as the video4linux
-device.
-
-The ioctls that deal with SPUs (sub picture units) and navigation
-packets are only supported on some MPEG decoders made for DVD playback.
-
-These ioctls were also used by V4L2 to control MPEG decoders implemented
-in V4L2. The use of these ioctls for that purpose has been made obsolete
-and proper V4L2 ioctls or controls have been created to replace that
-functionality.

-
-****************
-Video Data Types
-****************
-
-
-.. _video-format-t:
-
-video_format_t
-==============
-
-The ``video_format_t`` data type defined by
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_FORMAT_4_3,     /* Select 4:3 format */
-	VIDEO_FORMAT_16_9,    /* Select 16:9 format. */
-	VIDEO_FORMAT_221_1    /* 2.21:1 */
-    } video_format_t;
-
-is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
-aspect ratio the output hardware (e.g. TV) has. It is also used in the
-data structures video_status (??) returned by VIDEO_GET_STATUS (??)
-and video_event (??) returned by VIDEO_GET_EVENT (??) which report
-about the display format of the current video stream.
-
-
-.. _video-displayformat-t:
-
-video_displayformat_t
-=====================
-
-In case the display format of the video stream and of the display
-hardware differ the application has to specify how to handle the
-cropping of the picture. This can be done using the
-VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_PAN_SCAN,       /* use pan and scan format */
-	VIDEO_LETTER_BOX,     /* use letterbox format */
-	VIDEO_CENTER_CUT_OUT  /* use center cut out format */
-    } video_displayformat_t;
-
-as argument.
-
-
-.. _video-stream-source-t:
-
-video_stream_source_t
-=====================
-
-The video stream source is set through the VIDEO_SELECT_SOURCE call
-and can take the following values, depending on whether we are replaying
-from an internal (demuxer) or external (user write) source.
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
-	VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
-		       comes from the user through the write
-		       system call */
-    } video_stream_source_t;
-
-VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
-frontend or the DVR device) as the source of the video stream. If
-VIDEO_SOURCE_MEMORY is selected the stream comes from the application
-through the **write()** system call.
-
-
-.. _video-play-state-t:
-
-video_play_state_t
-==================
-
-The following values can be returned by the VIDEO_GET_STATUS call
-representing the state of video playback.
-
-
-.. code-block:: c
-
-    typedef enum {
-	VIDEO_STOPPED, /* Video is stopped */
-	VIDEO_PLAYING, /* Video is currently playing */
-	VIDEO_FREEZED  /* Video is freezed */
-    } video_play_state_t;
-
-
-.. c:type:: video_command
-
-struct video_command
-====================
-
-The structure must be zeroed before use by the application This ensures
-it can be extended safely in the future.
-
-
-.. code-block:: c
-
-    struct video_command {
-	__u32 cmd;
-	__u32 flags;
-	union {
-	    struct {
-		__u64 pts;
-	    } stop;
-
-	    struct {
-		/* 0 or 1000 specifies normal speed,
-		   1 specifies forward single stepping,
-		   -1 specifies backward single stepping,
-		   >>1: playback at speed/1000 of the normal speed,
-		   <-1: reverse playback at (-speed/1000) of the normal speed. */
-		__s32 speed;
-		__u32 format;
-	    } play;
-
-	    struct {
-		__u32 data[16];
-	    } raw;
-	};
-    };
-
-
-.. _video-size-t:
-
-video_size_t
-============
-
-
-.. code-block:: c
-
-    typedef struct {
-	int w;
-	int h;
-	video_format_t aspect_ratio;
-    } video_size_t;
-
-
-.. c:type:: video_event
-
-struct video_event
-==================
-
-The following is the structure of a video event as it is returned by the
-VIDEO_GET_EVENT call.
-
-
-.. code-block:: c
-
-    struct video_event {
-	__s32 type;
-    #define VIDEO_EVENT_SIZE_CHANGED    1
-    #define VIDEO_EVENT_FRAME_RATE_CHANGED  2
-    #define VIDEO_EVENT_DECODER_STOPPED     3
-    #define VIDEO_EVENT_VSYNC       4
-	long timestamp;
-	union {
-	    video_size_t size;
-	    unsigned int frame_rate;    /* in frames per 1000sec */
-	    unsigned char vsync_field;  /* unknown/odd/even/progressive */
-	} u;
-    };
-
-
-.. c:type:: video_status
-
-struct video_status
-===================
-
-The VIDEO_GET_STATUS call returns the following structure informing
-about various states of the playback operation.
-
-
-.. code-block:: c
-
-    struct video_status {
-	int                   video_blank;   /* blank video on freeze? */
-	video_play_state_t    play_state;    /* current state of playback */
-	video_stream_source_t stream_source; /* current source (demux/memory) */
-	video_format_t        video_format;  /* current aspect ratio of stream */
-	video_displayformat_t display_format;/* selected cropping mode */
-    };
-
-If video_blank is set video will be blanked out if the channel is
-changed or if playback is stopped. Otherwise, the last picture will be
-displayed. play_state indicates if the video is currently frozen,
-stopped, or being played back. The stream_source corresponds to the
-selected source for the video stream. It can come either from the
-demultiplexer or from memory. The video_format indicates the aspect
-ratio (one of 4:3 or 16:9) of the currently played video stream.
-Finally, display_format corresponds to the selected cropping mode in
-case the source video format is not the same as the format of the output
-device.
-
-
-.. c:type:: video_still_picture
-
-struct video_still_picture
-==========================
-
-An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
-within the following structure.
-
-
-.. code-block:: c
-
-    /* pointer to and size of a single iframe in memory */
-    struct video_still_picture {
-	char *iFrame;        /* pointer to a single iframe in memory */
-	int32_t size;
-    };
-
-
-.. _video_caps:
-
-video capabilities
-==================
-
-A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
-following bits set according to the hardwares capabilities.
-
-
-.. code-block:: c
-
-     /* bit definitions for capabilities: */
-     /* can the hardware decode MPEG1 and/or MPEG2? */
-     #define VIDEO_CAP_MPEG1   1
-     #define VIDEO_CAP_MPEG2   2
-     /* can you send a system and/or program stream to video device?
-	(you still have to open the video and the audio device but only
-	 send the stream to the video device) */
-     #define VIDEO_CAP_SYS     4
-     #define VIDEO_CAP_PROG    8
-     /* can the driver also handle SPU, NAVI and CSS encoded data?
-	(CSS API is not present yet) */
-     #define VIDEO_CAP_SPU    16
-     #define VIDEO_CAP_NAVI   32
-     #define VIDEO_CAP_CSS    64

-
-0. PREAMBLE
-===========
-
-The purpose of this License is to make a manual, textbook, or other
-written document “free” in the sense of freedom: to assure everyone the
-effective freedom to copy and redistribute it, with or without modifying
-it, either commercially or noncommercially. Secondarily, this License
-preserves for the author and publisher a way to get credit for their
-work, while not being considered responsible for modifications made by
-others.
-
-This License is a kind of “copyleft”, which means that derivative works
-of the document must themselves be free in the same sense. It
-complements the GNU General Public License, which is a copyleft license
-designed for free software.
-
-We have designed this License in order to use it for manuals for free
-software, because free software needs free documentation: a free program
-should come with manuals providing the same freedoms that the software
-does. But this License is not limited to software manuals; it can be
-used for any textual work, regardless of subject matter or whether it is
-published as a printed book. We recommend this License principally for
-works whose purpose is instruction or reference.
-
-
-.. _fdl-section1:
-
-1. APPLICABILITY AND DEFINITIONS
-================================
-
-
-.. _fdl-document:
-
-This License applies to any manual or other work that contains a notice
-placed by the copyright holder saying it can be distributed under the
-terms of this License. The “Document”, below, refers to any such manual
-or work. Any member of the public is a licensee, and is addressed as
-“you”.
-
-
-.. _fdl-modified:
-
-A “Modified Version” of the Document means any work containing the
-Document or a portion of it, either copied verbatim, or with
-modifications and/or translated into another language.
-
-
-.. _fdl-secondary:
-
-A “Secondary Section” is a named appendix or a front-matter section of
-the :ref:`Document <fdl-document>` that deals exclusively with the
-relationship of the publishers or authors of the Document to the
-Document's overall subject (or to related matters) and contains nothing
-that could fall directly within that overall subject. (For example, if
-the Document is in part a textbook of mathematics, a Secondary Section
-may not explain any mathematics.) The relationship could be a matter of
-historical connection with the subject or with related matters, or of
-legal, commercial, philosophical, ethical or political position
-regarding them.
-
-
-.. _fdl-invariant:
-
-The “Invariant Sections” are certain
-:ref:`Secondary Sections <fdl-secondary>` whose titles are designated,
-as being those of Invariant Sections, in the notice that says that the
-:ref:`Document <fdl-document>` is released under this License.
-
-
-.. _fdl-cover-texts:
-
-The “Cover Texts” are certain short passages of text that are listed, as
-Front-Cover Texts or Back-Cover Texts, in the notice that says that the
-:ref:`Document <fdl-document>` is released under this License.
-
-
-.. _fdl-transparent:
-
-A “Transparent” copy of the :ref:`Document <fdl-document>` means a
-machine-readable copy, represented in a format whose specification is
-available to the general public, whose contents can be viewed and edited
-directly and straightforwardly with generic text editors or (for images
-composed of pixels) generic paint programs or (for drawings) some widely
-available drawing editor, and that is suitable for input to text
-formatters or for automatic translation to a variety of formats suitable
-for input to text formatters. A copy made in an otherwise Transparent
-file format whose markup has been designed to thwart or discourage
-subsequent modification by readers is not Transparent. A copy that is
-not “Transparent” is called “Opaque”.
-
-Examples of suitable formats for Transparent copies include plain ASCII
-without markup, Texinfo input format, LaTeX input format, SGML or XML
-using a publicly available DTD, and standard-conforming simple HTML
-designed for human modification. Opaque formats include PostScript, PDF,
-proprietary formats that can be read and edited only by proprietary word
-processors, SGML or XML for which the DTD and/or processing tools are
-not generally available, and the machine-generated HTML produced by some
-word processors for output purposes only.
-
-
-.. _fdl-title-page:
-
-The “Title Page” means, for a printed book, the title page itself, plus
-such following pages as are needed to hold, legibly, the material this
-License requires to appear in the title page. For works in formats which
-do not have any title page as such, “Title Page” means the text near the
-most prominent appearance of the work's title, preceding the beginning
-of the body of the text.
-
-
-.. _fdl-section2:
-
-2. VERBATIM COPYING
-===================
-
-You may copy and distribute the :ref:`Document <fdl-document>` in any
-medium, either commercially or noncommercially, provided that this
-License, the copyright notices, and the license notice saying this
-License applies to the Document are reproduced in all copies, and that
-you add no other conditions whatsoever to those of this License. You may
-not use technical measures to obstruct or control the reading or further
-copying of the copies you make or distribute. However, you may accept
-compensation in exchange for copies. If you distribute a large enough
-number of copies you must also follow the conditions in
-:ref:`section 3 <fdl-section3>`.
-
-You may also lend copies, under the same conditions stated above, and
-you may publicly display copies.
-
-
-.. _fdl-section3:
-
-3. COPYING IN QUANTITY
-======================
-
-If you publish printed copies of the :ref:`Document <fdl-document>`
-numbering more than 100, and the Document's license notice requires
-:ref:`Cover Texts <fdl-cover-texts>`, you must enclose the copies in
-covers that carry, clearly and legibly, all these Cover Texts:
-Front-Cover Texts on the front cover, and Back-Cover Texts on the back
-cover. Both covers must also clearly and legibly identify you as the
-publisher of these copies. The front cover must present the full title
-with all words of the title equally prominent and visible. You may add
-other material on the covers in addition. Copying with changes limited
-to the covers, as long as they preserve the title of the
-:ref:`Document <fdl-document>` and satisfy these conditions, can be
-treated as verbatim copying in other respects.
-
-If the required texts for either cover are too voluminous to fit
-legibly, you should put the first ones listed (as many as fit
-reasonably) on the actual cover, and continue the rest onto adjacent
-pages.
-
-If you publish or distribute :ref:`Opaque <fdl-transparent>` copies of
-the :ref:`Document <fdl-document>` numbering more than 100, you must
-either include a machine-readable :ref:`Transparent <fdl-transparent>`
-copy along with each Opaque copy, or state in or with each Opaque copy a
-publicly-accessible computer-network location containing a complete
-Transparent copy of the Document, free of added material, which the
-general network-using public has access to download anonymously at no
-charge using public-standard network protocols. If you use the latter
-option, you must take reasonably prudent steps, when you begin
-distribution of Opaque copies in quantity, to ensure that this
-Transparent copy will remain thus accessible at the stated location
-until at least one year after the last time you distribute an Opaque
-copy (directly or through your agents or retailers) of that edition to
-the public.
-
-It is requested, but not required, that you contact the authors of the
-:ref:`Document <fdl-document>` well before redistributing any large
-number of copies, to give them a chance to provide you with an updated
-version of the Document.
-
-
-.. _fdl-section4:
-
-4. MODIFICATIONS
-================
-
-You may copy and distribute a :ref:`Modified Version <fdl-modified>`
-of the :ref:`Document <fdl-document>` under the conditions of sections
-:ref:`2 <fdl-section2>` and :ref:`3 <fdl-section3>` above, provided
-that you release the Modified Version under precisely this License, with
-the Modified Version filling the role of the Document, thus licensing
-distribution and modification of the Modified Version to whoever
-possesses a copy of it. In addition, you must do these things in the
-Modified Version:
-
--  **A.**
-   Use in the :ref:`Title Page <fdl-title-page>` (and on the covers,
-   if any) a title distinct from that of the
-   :ref:`Document <fdl-document>`, and from those of previous versions
-   (which should, if there were any, be listed in the History section of
-   the Document). You may use the same title as a previous version if
-   the original publisher of that version gives permission.
-
--  **B.**
-   List on the :ref:`Title Page <fdl-title-page>`, as authors, one or
-   more persons or entities responsible for authorship of the
-   modifications in the :ref:`Modified Version <fdl-modified>`,
-   together with at least five of the principal authors of the
-   :ref:`Document <fdl-document>` (all of its principal authors, if it
-   has less than five).
-
--  **C.**
-   State on the :ref:`Title Page <fdl-title-page>` the name of the
-   publisher of the :ref:`Modified Version <fdl-modified>`, as the
-   publisher.
-
--  **D.**
-   Preserve all the copyright notices of the
-   :ref:`Document <fdl-document>`.
-
--  **E.**
-   Add an appropriate copyright notice for your modifications adjacent
-   to the other copyright notices.
-
--  **F.**
-   Include, immediately after the copyright notices, a license notice
-   giving the public permission to use the
-   :ref:`Modified Version <fdl-modified>` under the terms of this
-   License, in the form shown in the Addendum below.
-
--  **G.**
-   Preserve in that license notice the full lists of
-   :ref:`Invariant Sections <fdl-invariant>` and required
-   :ref:`Cover Texts <fdl-cover-texts>` given in the
-   :ref:`Document's <fdl-document>` license notice.
-
--  **H.**
-   Include an unaltered copy of this License.
-
--  **I.**
-   Preserve the section entitled “History”, and its title, and add to it
-   an item stating at least the title, year, new authors, and publisher
-   of the :ref:`Modified Version <fdl-modified>` as given on the
-   :ref:`Title Page <fdl-title-page>`. If there is no section entitled
-   “History” in the :ref:`Document <fdl-document>`, create one stating
-   the title, year, authors, and publisher of the Document as given on
-   its Title Page, then add an item describing the Modified Version as
-   stated in the previous sentence.
-
--  **J.**
-   Preserve the network location, if any, given in the
-   :ref:`Document <fdl-document>` for public access to a
-   :ref:`Transparent <fdl-transparent>` copy of the Document, and
-   likewise the network locations given in the Document for previous
-   versions it was based on. These may be placed in the “History”
-   section. You may omit a network location for a work that was
-   published at least four years before the Document itself, or if the
-   original publisher of the version it refers to gives permission.
-
--  **K.**
-   In any section entitled “Acknowledgements” or “Dedications”, preserve
-   the section's title, and preserve in the section all the substance
-   and tone of each of the contributor acknowledgements and/or
-   dedications given therein.
-
--  **L.**
-   Preserve all the :ref:`Invariant Sections <fdl-invariant>` of the
-   :ref:`Document <fdl-document>`, unaltered in their text and in
-   their titles. Section numbers or the equivalent are not considered
-   part of the section titles.
-
--  **M.**
-   Delete any section entitled “Endorsements”. Such a section may not be
-   included in the :ref:`Modified Version <fdl-modified>`.
-
--  **N.**
-   Do not retitle any existing section as “Endorsements” or to conflict
-   in title with any :ref:`Invariant Section <fdl-invariant>`.
-
-If the :ref:`Modified Version <fdl-modified>` includes new
-front-matter sections or appendices that qualify as
-:ref:`Secondary Sections <fdl-secondary>` and contain no material
-copied from the Document, you may at your option designate some or all
-of these sections as invariant. To do this, add their titles to the list
-of :ref:`Invariant Sections <fdl-invariant>` in the Modified Version's
-license notice. These titles must be distinct from any other section
-titles.
-
-You may add a section entitled “Endorsements”, provided it contains
-nothing but endorsements of your
-:ref:`Modified Version <fdl-modified>` by various parties--for
-example, statements of peer review or that the text has been approved by
-an organization as the authoritative definition of a standard.
-
-You may add a passage of up to five words as a
-:ref:`Front-Cover Text <fdl-cover-texts>`, and a passage of up to 25
-words as a :ref:`Back-Cover Text <fdl-cover-texts>`, to the end of the
-list of :ref:`Cover Texts <fdl-cover-texts>` in the
-:ref:`Modified Version <fdl-modified>`. Only one passage of
-Front-Cover Text and one of Back-Cover Text may be added by (or through
-arrangements made by) any one entity. If the
-:ref:`Document <fdl-document>` already includes a cover text for the
-same cover, previously added by you or by arrangement made by the same
-entity you are acting on behalf of, you may not add another; but you may
-replace the old one, on explicit permission from the previous publisher
-that added the old one.
-
-The author(s) and publisher(s) of the :ref:`Document <fdl-document>`
-do not by this License give permission to use their names for publicity
-for or to assert or imply endorsement of any
-:ref:`Modified Version <fdl-modified>`.

-
-5. COMBINING DOCUMENTS
-======================
-
-You may combine the :ref:`Document <fdl-document>` with other
-documents released under this License, under the terms defined in
-:ref:`section 4 <fdl-section4>` above for modified versions, provided
-that you include in the combination all of the
-:ref:`Invariant Sections <fdl-invariant>` of all of the original
-documents, unmodified, and list them all as Invariant Sections of your
-combined work in its license notice.
-
-The combined work need only contain one copy of this License, and
-multiple identical :ref:`Invariant Sections <fdl-invariant>` may be
-replaced with a single copy. If there are multiple Invariant Sections
-with the same name but different contents, make the title of each such
-section unique by adding at the end of it, in parentheses, the name of
-the original author or publisher of that section if known, or else a
-unique number. Make the same adjustment to the section titles in the
-list of Invariant Sections in the license notice of the combined work.
-
-In the combination, you must combine any sections entitled “History” in
-the various original documents, forming one section entitled “History”;
-likewise combine any sections entitled “Acknowledgements”, and any
-sections entitled “Dedications”. You must delete all sections entitled
-“Endorsements.”
-
-
-.. _fdl-section6:
-
-6. COLLECTIONS OF DOCUMENTS
-===========================
-
-You may make a collection consisting of the
-:ref:`Document <fdl-document>` and other documents released under this
-License, and replace the individual copies of this License in the
-various documents with a single copy that is included in the collection,
-provided that you follow the rules of this License for verbatim copying
-of each of the documents in all other respects.
-
-You may extract a single document from such a collection, and distribute
-it individually under this License, provided you insert a copy of this
-License into the extracted document, and follow this License in all
-other respects regarding verbatim copying of that document.
-
-
-.. _fdl-section7:
-
-7. AGGREGATION WITH INDEPENDENT WORKS
-=====================================
-
-A compilation of the :ref:`Document <fdl-document>` or its derivatives
-with other separate and independent documents or works, in or on a
-volume of a storage or distribution medium, does not as a whole count as
-a :ref:`Modified Version <fdl-modified>` of the Document, provided no
-compilation copyright is claimed for the compilation. Such a compilation
-is called an “aggregate”, and this License does not apply to the other
-self-contained works thus compiled with the Document , on account of
-their being thus compiled, if they are not themselves derivative works
-of the Document. If the :ref:`Cover Text <fdl-cover-texts>`
-requirement of :ref:`section 3 <fdl-section3>` is applicable to these
-copies of the Document, then if the Document is less than one quarter of
-the entire aggregate, the Document's Cover Texts may be placed on covers
-that surround only the Document within the aggregate. Otherwise they
-must appear on covers around the whole aggregate.
-
-
-.. _fdl-section8:
-
-8. TRANSLATION
-==============
-
-Translation is considered a kind of modification, so you may distribute
-translations of the :ref:`Document <fdl-document>` under the terms of
-:ref:`section 4 <fdl-section4>`. Replacing
-:ref:`Invariant Sections <fdl-invariant>` with translations requires
-special permission from their copyright holders, but you may include
-translations of some or all Invariant Sections in addition to the
-original versions of these Invariant Sections. You may include a
-translation of this License provided that you also include the original
-English version of this License. In case of a disagreement between the
-translation and the original English version of this License, the
-original English version will prevail.
-
-
-.. _fdl-section9:
-
-9. TERMINATION
-==============
-
-You may not copy, modify, sublicense, or distribute the
-:ref:`Document <fdl-document>` except as expressly provided for under
-this License. Any other attempt to copy, modify, sublicense or
-distribute the Document is void, and will automatically terminate your
-rights under this License. However, parties who have received copies, or
-rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-
-.. _fdl-section10:

-
-    -  -  ``EAGAIN`` (aka ``EWOULDBLOCK``)
-
-       -  The ioctl can't be handled because the device is in state where it
-	  can't perform it. This could happen for example in case where
-	  device is sleeping and ioctl is performed to query statistics. It
-	  is also returned when the ioctl would need to wait for an event,
-	  but the device was opened in non-blocking mode.
-
-    -  -  ``EBADF``
-
-       -  The file descriptor is not a valid.
-
-    -  -  ``EBUSY``
-
-       -  The ioctl can't be handled because the device is busy. This is
-	  typically return while device is streaming, and an ioctl tried to
-	  change something that would affect the stream, or would require
-	  the usage of a hardware resource that was already allocated. The
-	  ioctl must not be retried without performing another action to fix
-	  the problem first (typically: stop the stream before retrying).
-
-    -  -  ``EFAULT``
-
-       -  There was a failure while copying data from/to userspace, probably
-	  caused by an invalid pointer reference.
-
-    -  -  ``EINVAL``
-
-       -  One or more of the ioctl parameters are invalid or out of the
-	  allowed range. This is a widely used error code. See the
-	  individual ioctl requests for specific causes.
-
-    -  -  ``ENODEV``
-
-       -  Device not found or was removed.
-
-    -  -  ``ENOMEM``
-
-       -  There's not enough memory to handle the desired operation.
-
-    -  -  ``ENOTTY``
-
-       -  The ioctl is not supported by the driver, actually meaning that
-	  the required functionality is not available, or the file
-	  descriptor is not for a media device.
-
-    -  -  ``ENOSPC``
-
-       -  On USB devices, the stream ioctl's can return this error, meaning
-	  that this request would overcommit the usb bandwidth reserved for
-	  periodic transfers (up to 80% of the USB bandwidth).
-
-    -  -  ``EPERM``
-
-       -  Permission denied. Can be returned if the device needs write
-	  permission, or some special capabilities is needed (e. g. root)
-
-    -  -  ``EIO``
-
-       -  I/O error. Typically used when there are problems communicating with

-Introduction
-============
-
-Media devices increasingly handle multiple related functions. Many USB
-cameras include microphones, video capture hardware can also output
-video, or SoC camera interfaces also perform memory-to-memory operations
-similar to video codecs.
-
-Independent functions, even when implemented in the same hardware, can
-be modelled as separate devices. A USB camera with a microphone will be
-presented to userspace applications as V4L2 and ALSA capture devices.
-The devices' relationships (when using a webcam, end-users shouldn't
-have to manually select the associated USB microphone), while not made
-available directly to applications by the drivers, can usually be
-retrieved from sysfs.
-
-With more and more advanced SoC devices being introduced, the current
-approach will not scale. Device topologies are getting increasingly
-complex and can't always be represented by a tree structure. Hardware
-blocks are shared between different functions, creating dependencies
-between seemingly unrelated devices.
-
-Kernel abstraction APIs such as V4L2 and ALSA provide means for
-applications to access hardware parameters. As newer hardware expose an
-increasingly high number of those parameters, drivers need to guess what
-applications really require based on limited information, thereby
-implementing policies that belong to userspace.
-
-The media controller API aims at solving those problems.

-Media device model
-==================
-
-Discovering a device internal topology, and configuring it at runtime,
-is one of the goals of the media controller API. To achieve this,
-hardware devices and Linux Kernel interfaces are modelled as graph
-objects on an oriented graph. The object types that constitute the graph
-are:
-
--  An **entity** is a basic media hardware or software building block.
-   It can correspond to a large variety of logical blocks such as
-   physical hardware devices (CMOS sensor for instance), logical
-   hardware devices (a building block in a System-on-Chip image
-   processing pipeline), DMA channels or physical connectors.
-
--  An **interface** is a graph representation of a Linux Kernel
-   userspace API interface, like a device node or a sysfs file that
-   controls one or more entities in the graph.
-
--  A **pad** is a data connection endpoint through which an entity can
-   interact with other entities. Data (not restricted to video) produced
-   by an entity flows from the entity's output to one or more entity
-   inputs. Pads should not be confused with physical pins at chip
-   boundaries.
-
--  A **data link** is a point-to-point oriented connection between two
-   pads, either on the same entity or on different entities. Data flows
-   from a source pad to a sink pad.
-
--  An **interface link** is a point-to-point bidirectional control
-   connection between a Linux Kernel interface and an entity.

-
-The ioctl ``request`` code specifies the media function to be called. It
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes.
-
-Macros and structures definitions specifying media ioctl requests and

-requests, their respective function and parameters are specified in
-:ref:`media-user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-Request-specific error codes are listed in the individual requests
-descriptions.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-
-Description
-===========
-
-All media devices must support the ``MEDIA_IOC_DEVICE_INFO`` ioctl. To
-query device information, applications call the ioctl with a pointer to
-a struct :c:type:`media_device_info`. The driver
-fills the structure and returns the information to the application. The
-ioctl never fails.

-
-	  Driver specific applications can use this information to verify
-	  the driver identity. It is also useful to work around known bugs,
-	  or to identify drivers in error reports.

-
-
-The ``serial`` and ``bus_info`` fields can be used to distinguish
-between multiple instances of otherwise identical hardware. The serial
-number takes precedence when provided and can be assumed to be unique.
-If the serial number is an empty string, the ``bus_info`` field can be
-used instead. The ``bus_info`` field is guaranteed to be unique, but can
-vary across reboots or device unplug/replug.

-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the

-    :name: MEDIA_IOC_REQUEST_ALLOC
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <media-func-open>`.
-
-``argp``
-    Pointer to an integer.
-
-
-Description
-===========
-
-If the media device supports :ref:`requests <media-request-api>`, then
-this ioctl can be used to allocate a request. If it is not supported, then
-``errno`` is set to ``ENOTTY``. A request is accessed through a file descriptor
-that is returned in ``*argp``.
-
-If the request was successfully allocated, then the request file descriptor
-can be passed to the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctls.
-
-In addition, the request can be queued by calling
-:ref:`MEDIA_REQUEST_IOC_QUEUE` and re-initialized by calling
-:ref:`MEDIA_REQUEST_IOC_REINIT`.
-
-Finally, the file descriptor can be :ref:`polled <request-func-poll>` to wait
-for the request to complete.
-
-The request will remain allocated until all the file descriptors associated
-with it are closed by :ref:`close() <request-func-close>` and the driver no
-longer uses the request internally. See also
-:ref:`here <media-request-life-time>` for more information.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-ENOTTY
-    The driver has no support for requests.

-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, MEDIA_IOC_SETUP_LINK, struct media_link_desc *argp )
-    :name: MEDIA_IOC_SETUP_LINK
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <media-func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`media_link_desc`.
-
-
-Description
-===========
-
-To change link properties applications fill a struct
-:c:type:`media_link_desc` with link identification
-information (source and sink pad) and the new requested link flags. They
-then call the MEDIA_IOC_SETUP_LINK ioctl with a pointer to that
-structure.
-
-The only configurable property is the ``ENABLED`` link flag to
-enable/disable a link. Links marked with the ``IMMUTABLE`` link flag can
-not be enabled or disabled.
-
-Link configuration has no side effect on other links. If an enabled link
-at the sink pad prevents the link from being enabled, the driver returns
-with an ``EBUSY`` error code.
-
-Only links marked with the ``DYNAMIC`` link flag can be enabled/disabled
-while streaming media data. Attempting to enable or disable a streaming
-non-dynamic link will return an ``EBUSY`` error code.
-
-If the specified link can't be found the driver returns with an ``EINVAL``
-error code.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    The struct :c:type:`media_link_desc` references a
-    non-existing link, or the link is immutable and an attempt to modify
-    its configuration was made.

-
-
-Synopsis

-

-    :name: MEDIA_REQUEST_IOC_QUEUE
-
-
-Arguments
-=========
-
-``request_fd``
-    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
-
-
-Description
-===========
-
-If the media device supports :ref:`requests <media-request-api>`, then
-this request ioctl can be used to queue a previously allocated request.
-
-If the request was successfully queued, then the file descriptor can be
-:ref:`polled <request-func-poll>` to wait for the request to complete.
-
-If the request was already queued before, then ``EBUSY`` is returned.
-Other errors can be returned if the contents of the request contained
-invalid or inconsistent data, see the next section for a list of
-common error codes. On error both the request and driver state are unchanged.
-
-Once a request is queued, then the driver is required to gracefully handle
-errors that occur when the request is applied to the hardware. The
-exception is the ``EIO`` error which signals a fatal error that requires
-the application to stop streaming to reset the hardware state.
-
-It is not allowed to mix queuing requests with queuing buffers directly
-(without a request). ``EBUSY`` will be returned if the first buffer was
-queued directly and you next try to queue a request, or vice versa.
-
-A request must contain at least one buffer, otherwise this ioctl will
-return an ``ENOENT`` error.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EBUSY
-    The request was already queued or the application queued the first
-    buffer directly, but later attempted to use a request. It is not permitted
-    to mix the two APIs.
-ENOENT
-    The request did not contain any buffers. All requests are required
-    to have at least one buffer. This can also be returned if some required
-    configuration is missing in the request.
-ENOMEM
-    Out of memory when allocating internal data structures for this
-    request.
-EINVAL
-    The request has invalid data.
-EIO
-    The hardware is in a bad state. To recover, the application needs to
-    stop streaming to reset the hardware state and then try to restart
-    streaming.

-Description
-===========
-
-If the media device supports :ref:`requests <media-request-api>`, then
-this request ioctl can be used to re-initialize a previously allocated
-request.
-
-Re-initializing a request will clear any existing data from the request.
-This avoids having to :ref:`close() <request-func-close>` a completed
-request and allocate a new request. Instead the completed request can just
-be re-initialized and it is ready to be used again.
-
-A request can only be re-initialized if it either has not been queued
-yet, or if it was queued and completed. Otherwise it will set ``errno``
-to ``EBUSY``. No other error codes can be returned.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately.
-
-EBUSY
-    The request is queued but not yet completed.

-Request API
-===========
-
-The Request API has been designed to allow V4L2 to deal with requirements of
-modern devices (stateless codecs, complex camera pipelines, ...) and APIs
-(Android Codec v2). One such requirement is the ability for devices belonging to
-the same pipeline to reconfigure and collaborate closely on a per-frame basis.
-Another is support of stateless codecs, which require controls to be applied
-to specific frames (aka 'per-frame controls') in order to be used efficiently.
-
-While the initial use-case was V4L2, it can be extended to other subsystems
-as well, as long as they use the media controller.
-
-Supporting these features without the Request API is not always possible and if
-it is, it is terribly inefficient: user-space would have to flush all activity
-on the media pipeline, reconfigure it for the next frame, queue the buffers to
-be processed with that configuration, and wait until they are all available for
-dequeuing before considering the next frame. This defeats the purpose of having
-buffer queues since in practice only one buffer would be queued at a time.
-
-The Request API allows a specific configuration of the pipeline (media
-controller topology + configuration for each media entity) to be associated with
-specific buffers. This allows user-space to schedule several tasks ("requests")
-with different configurations in advance, knowing that the configuration will be
-applied when needed to get the expected result. Configuration values at the time
-of request completion are also available for reading.
-
-General Usage
--------------
-
-The Request API extends the Media Controller API and cooperates with
-subsystem-specific APIs to support request usage. At the Media Controller
-level, requests are allocated from the supporting Media Controller device
-node. Their life cycle is then managed through the request file descriptors in
-an opaque way. Configuration data, buffer handles and processing results
-stored in requests are accessed through subsystem-specific APIs extended for
-request support, such as V4L2 APIs that take an explicit ``request_fd``
-parameter.
-
-Request Allocation
-------------------
-
-User-space allocates requests using :ref:`MEDIA_IOC_REQUEST_ALLOC`
-for the media device node. This returns a file descriptor representing the
-request. Typically, several such requests will be allocated.
-
-Request Preparation
--------------------
-
-Standard V4L2 ioctls can then receive a request file descriptor to express the
-fact that the ioctl is part of said request, and is not to be applied
-immediately. See :ref:`MEDIA_IOC_REQUEST_ALLOC` for a list of ioctls that
-support this. Configurations set with a ``request_fd`` parameter are stored
-instead of being immediately applied, and buffers queued to a request do not
-enter the regular buffer queue until the request itself is queued.
-
-Request Submission
-------------------
-
-Once the configuration and buffers of the request are specified, it can be
-queued by calling :ref:`MEDIA_REQUEST_IOC_QUEUE` on the request file descriptor.
-A request must contain at least one buffer, otherwise ``ENOENT`` is returned.
-A queued request cannot be modified anymore.
-
-.. caution::
-   For :ref:`memory-to-memory devices <mem2mem>` you can use requests only for
-   output buffers, not for capture buffers. Attempting to add a capture buffer
-   to a request will result in an ``EBADR`` error.
-
-If the request contains configurations for multiple entities, individual drivers
-may synchronize so the requested pipeline's topology is applied before the
-buffers are processed. Media controller drivers do a best effort implementation
-since perfect atomicity may not be possible due to hardware limitations.
-
-.. caution::
-
-   It is not allowed to mix queuing requests with directly queuing buffers:
-   whichever method is used first locks this in place until
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called or the device is
-   :ref:`closed <func-close>`. Attempts to directly queue a buffer when earlier
-   a buffer was queued via a request or vice versa will result in an ``EBUSY``
-   error.
-
-Controls can still be set without a request and are applied immediately,
-regardless of whether a request is in use or not.
-
-.. caution::
-
-   Setting the same control through a request and also directly can lead to
-   undefined behavior!
-
-User-space can :ref:`poll() <request-func-poll>` a request file descriptor in
-order to wait until the request completes. A request is considered complete
-once all its associated buffers are available for dequeuing and all the
-associated controls have been updated with the values at the time of completion.
-Note that user-space does not need to wait for the request to complete to
-dequeue its buffers: buffers that are available halfway through a request can
-be dequeued independently of the request's state.
-
-A completed request contains the state of the device after the request was
-executed. User-space can query that state by calling
-:ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` with the request file
-descriptor. Calling :ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
-request that has been queued but not yet completed will return ``EBUSY``
-since the control values might be changed at any time by the driver while the
-request is in flight.
-
-.. _media-request-life-time:
-
-Recycling and Destruction
--------------------------
-
-Finally, a completed request can either be discarded or be reused. Calling
-:ref:`close() <request-func-close>` on a request file descriptor will make
-that file descriptor unusable and the request will be freed once it is no
-longer in use by the kernel. That is, if the request is queued and then the
-file descriptor is closed, then it won't be freed until the driver completed
-the request.
-
-The :ref:`MEDIA_REQUEST_IOC_REINIT` will clear a request's state and make it
-available again. No state is retained by this operation: the request is as
-if it had just been allocated.
-
-Example for a Codec Device
---------------------------
-
-For use-cases such as :ref:`codecs <mem2mem>`, the request API can be used
-to associate specific controls to
-be applied by the driver for the OUTPUT buffer, allowing user-space
-to queue many such buffers in advance. It can also take advantage of requests'
-ability to capture the state of controls when the request completes to read back
-information that may be subject to change.
-
-Put into code, after obtaining a request, user-space can assign controls and one
-OUTPUT buffer to it:
-
-.. code-block:: c
-
-	struct v4l2_buffer buf;
-	struct v4l2_ext_controls ctrls;
-	int req_fd;
-	...
-	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
-		return errno;
-	...
-	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
-	ctrls.request_fd = req_fd;
-	if (ioctl(codec_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
-		return errno;
-	...
-	buf.type = V4L2_BUF_TYPE_VIDEO_OUTPUT;
-	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
-	buf.request_fd = req_fd;
-	if (ioctl(codec_fd, VIDIOC_QBUF, &buf))
-		return errno;
-
-Note that it is not allowed to use the Request API for CAPTURE buffers
-since there are no per-frame settings to report there.
-
-Once the request is fully prepared, it can be queued to the driver:
-
-.. code-block:: c
-
-	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
-		return errno;
-
-User-space can then either wait for the request to complete by calling poll() on
-its file descriptor, or start dequeuing CAPTURE buffers. Most likely, it will
-want to get CAPTURE buffers as soon as possible and this can be done using a
-regular :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`:
-
-.. code-block:: c
-
-	struct v4l2_buffer buf;
-
-	memset(&buf, 0, sizeof(buf));
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-	if (ioctl(codec_fd, VIDIOC_DQBUF, &buf))
-		return errno;
-
-Note that this example assumes for simplicity that for every OUTPUT buffer
-there will be one CAPTURE buffer, but this does not have to be the case.
-
-We can then, after ensuring that the request is completed via polling the
-request file descriptor, query control values at the time of its completion via
-a call to :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.
-This is particularly useful for volatile controls for which we want to
-query values as soon as the capture buffer is produced.
-
-.. code-block:: c
-
-	struct pollfd pfd = { .events = POLLPRI, .fd = req_fd };
-	poll(&pfd, 1, -1);
-	...
-	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
-	ctrls.request_fd = req_fd;
-	if (ioctl(codec_fd, VIDIOC_G_EXT_CTRLS, &ctrls))
-		return errno;
-
-Once we don't need the request anymore, we can either recycle it for reuse with
-:ref:`MEDIA_REQUEST_IOC_REINIT`...
-
-.. code-block:: c
-
-	if (ioctl(req_fd, MEDIA_REQUEST_IOC_REINIT))
-		return errno;
-
-... or close its file descriptor to completely dispose of it.
-
-.. code-block:: c
-
-	close(req_fd);
-
-Example for a Simple Capture Device
------------------------------------
-
-With a simple capture device, requests can be used to specify controls to apply
-for a given CAPTURE buffer.
-
-.. code-block:: c
-
-	struct v4l2_buffer buf;
-	struct v4l2_ext_controls ctrls;
-	int req_fd;
-	...
-	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
-		return errno;
-	...
-	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
-	ctrls.request_fd = req_fd;
-	if (ioctl(camera_fd, VIDIOC_S_EXT_CTRLS, &ctrls))

-
-    #include <sys/ioctl.h>
-
-
-.. c:function:: int ioctl( int fd, int cmd, void *argp )
-    :name: req-ioctl
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
-
-``cmd``
-    The request ioctl command code as defined in the media.h header file, for
-    example :ref:`MEDIA_REQUEST_IOC_QUEUE`.
-
-``argp``
-    Pointer to a request-specific structure.
-
-
-Description
-===========
-
-The :ref:`ioctl() <request-func-ioctl>` function manipulates request
-parameters. The argument ``fd`` must be an open file descriptor.
-
-The ioctl ``cmd`` code specifies the request function to be called. It
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes.
-
-Macros and structures definitions specifying request ioctl commands and
-their parameters are located in the media.h header file. All request ioctl
-commands, their respective function and parameters are specified in
-:ref:`media-user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-Command-specific error codes are listed in the individual command
-descriptions.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-
-
-Synopsis
-========
-
-.. code-block:: c
-
-    #include <sys/poll.h>
-
-
-.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
-   :name: request-poll
-
-Arguments
-=========
-
-``ufds``
-   List of file descriptor events to be watched
-
-``nfds``
-   Number of file descriptor events at the \*ufds array
-
-``timeout``
-   Timeout to wait for events
-
-
-Description
-===========
-
-With the :c:func:`poll() <request-func-poll>` function applications can wait
-for a request to complete.
-
-On success :c:func:`poll() <request-func-poll>` returns the number of file
-descriptors that have been selected (that is, file descriptors for which the
-``revents`` field of the respective struct :c:type:`pollfd`
-is non-zero). Request file descriptor set the ``POLLPRI`` flag in ``revents``
-when the request was completed.  When the function times out it returns
-a value of zero, on failure it returns -1 and the ``errno`` variable is
-set appropriately.
-
-Attempting to poll for a request that is not yet queued will
-set the ``POLLERR`` flag in ``revents``.
-
-
-Return Value
-============
-
-On success, :c:func:`poll() <request-func-poll>` returns the number of
-structures which have non-zero ``revents`` fields, or zero if the call
-timed out. On error -1 is returned, and the ``errno`` variable is set
-appropriately:
-
-``EBADF``
-    One or more of the ``ufds`` members specify an invalid file
-    descriptor.
-
-``EFAULT``
-    ``ufds`` references an inaccessible memory area.
-
-``EINTR``
-    The call was interrupted by a signal.
-
-``EINVAL``
-    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
-    ``getrlimit()`` to obtain this value.

-Introduction
-************
-
-LIRC stands for Linux Infrared Remote Control. The LIRC device interface is
-a bi-directional interface for transporting raw IR and decoded scancodes
-data between userspace and kernelspace. Fundamentally, it is just a chardev
-(/dev/lircX, for X = 0, 1, 2, ...), with a number of standard struct
-file_operations defined on it. With respect to transporting raw IR and
-decoded scancodes to and fro, the essential fops are read, write and ioctl.
-
-It is also possible to attach a BPF program to a LIRC device for decoding
-raw IR into scancodes.
-
-Example dmesg output upon a driver registering w/LIRC:
-
-.. code-block:: none
-
-    $ dmesg |grep lirc_dev
-    rc rc0: lirc_dev: driver mceusb registered at minor = 0, raw IR receiver, raw IR transmitter
-
-What you should see for a chardev:
-
-.. code-block:: none
-
-    $ ls -l /dev/lirc*
-    crw-rw---- 1 root root 248, 0 Jul 2 22:20 /dev/lirc0
-
-Note that the package `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_
-contains tools for working with LIRC devices:
-
- - ir-ctl: can receive raw IR and transmit IR, as well as query LIRC
-   device features.
-
- - ir-keytable: can load keymaps; allows you to set IR kernel protocols; load
-   BPF IR decoders and test IR decoding. Some BPF IR decoders are also
-   provided.
-
-.. _lirc_modes:
-
-**********
-LIRC modes
-**********
-
-LIRC supports some modes of receiving and sending IR codes, as shown
-on the following table.
-
-.. _lirc-mode-scancode:
-.. _lirc-scancode-flag-toggle:
-.. _lirc-scancode-flag-repeat:
-
-``LIRC_MODE_SCANCODE``
-
-    This mode is for both sending and receiving IR.
-
-    For transmitting (aka sending), create a ``struct lirc_scancode`` with
-    the desired scancode set in the ``scancode`` member, :c:type:`rc_proto`
-    set to the :ref:`IR protocol <Remote_controllers_Protocols>`, and all other
-    members set to 0. Write this struct to the lirc device.
-
-    For receiving, you read ``struct lirc_scancode`` from the LIRC device.
-    The ``scancode`` field is set to the received scancode and the
-    :ref:`IR protocol <Remote_controllers_Protocols>` is set in
-    :c:type:`rc_proto`. If the scancode maps to a valid key code, this is set
-    in the ``keycode`` field, else it is set to ``KEY_RESERVED``.
-
-    The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set if the toggle
-    bit is set in protocols that support it (e.g. rc-5 and rc-6), or
-    ``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
-    that support it (e.g. nec).
-
-    In the Sanyo and NEC protocol, if you hold a button on remote, rather than
-    repeating the entire scancode, the remote sends a shorter message with
-    no scancode, which just means button is held, a "repeat". When this is
-    received, the ``LIRC_SCANCODE_FLAG_REPEAT`` is set and the scancode and
-    keycode is repeated.
-
-    With nec, there is no way to distinguish "button hold" from "repeatedly
-    pressing the same button". The rc-5 and rc-6 protocols have a toggle bit.
-    When a button is released and pressed again, the toggle bit is inverted.
-    If the toggle bit is set, the ``LIRC_SCANCODE_FLAG_TOGGLE`` is set.
-
-    The ``timestamp`` field is filled with the time nanoseconds
-    (in ``CLOCK_MONOTONIC``) when the scancode was decoded.
-
-.. _lirc-mode-mode2:
-
-``LIRC_MODE_MODE2``
-
-    The driver returns a sequence of pulse and space codes to userspace,
-    as a series of u32 values.
-
-    This mode is used only for IR receive.
-
-    The upper 8 bits determine the packet type, and the lower 24 bits
-    the payload. Use ``LIRC_VALUE()`` macro to get the payload, and
-    the macro ``LIRC_MODE2()`` will give you the type, which
-    is one of:
-
-    ``LIRC_MODE2_PULSE``
-
-        Signifies the presence of IR in microseconds.
-
-    ``LIRC_MODE2_SPACE``
-
-        Signifies absence of IR in microseconds.
-
-    ``LIRC_MODE2_FREQUENCY``
-
-        If measurement of the carrier frequency was enabled with
-        :ref:`lirc_set_measure_carrier_mode` then this packet gives you
-        the carrier frequency in Hertz.
-
-    ``LIRC_MODE2_TIMEOUT``
-
-        If timeout reports are enabled with
-        :ref:`lirc_set_rec_timeout_reports`, when the timeout set with
-        :ref:`lirc_set_rec_timeout` expires due to no IR being detected,
-        this packet will be sent, with the number of microseconds with
-        no IR.
-
-.. _lirc-mode-pulse:
-
-``LIRC_MODE_PULSE``
-
-    In pulse mode, a sequence of pulse/space integer values are written to the
-    lirc device using :ref:`lirc-write`.
-
-    The values are alternating pulse and space lengths, in microseconds. The
-    first and last entry must be a pulse, so there must be an odd number
-    of entries.
-
-    This mode is used only for IR send.
-
-********************
-BPF based IR decoder
-********************
-
-The kernel has support for decoding the most common
-:ref:`IR protocols <Remote_controllers_Protocols>`, but there
-are many protocols which are not supported. To support these, it is possible
-to load an BPF program which does the decoding. This can only be done on
-LIRC devices which support reading raw IR.
-
-First, using the `bpf(2)`_ syscall with the ``BPF_LOAD_PROG`` argument,
-program must be loaded of type ``BPF_PROG_TYPE_LIRC_MODE2``. Once attached
-to the LIRC device, this program will be called for each pulse, space or

-pointer to a unsigned int, which is a :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>`
-value. When the program has decoded the scancode, it can be submitted using
-the BPF functions ``bpf_rc_keydown()`` or ``bpf_rc_repeat()``. Mouse or pointer
-movements can be reported using ``bpf_rc_pointer_rel()``.
-
-Once you have the file descriptor for the ``BPF_PROG_TYPE_LIRC_MODE2`` BPF
-program, it can be attached to the LIRC device using the `bpf(2)`_ syscall.
-The target must be the file descriptor for the LIRC device, and the
-attach type must be ``BPF_LIRC_MODE2``. No more than 64 BPF programs can be
-attached to a single LIRC device at a time.

-Synopsis
-========
-
-.. code-block:: c
-
-    #include <unistd.h>
-
-
-.. c:function:: ssize_t read( int fd, void *buf, size_t count )
-    :name: lirc-read
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by ``open()``.
-
-``buf``
-   Buffer to be filled
-
-``count``
-   Max number of bytes to read
-
-Description
-===========
-
-:ref:`read() <lirc-read>` attempts to read up to ``count`` bytes from file
-descriptor ``fd`` into the buffer starting at ``buf``.  If ``count`` is zero,
-:ref:`read() <lirc-read>` returns zero and has no other results. If ``count``
-is greater than ``SSIZE_MAX``, the result is unspecified.
-
-The exact format of the data depends on what :ref:`lirc_modes` a driver
-uses. Use :ref:`lirc_get_features` to get the supported mode, and use
-:ref:`lirc_set_rec_mode` set the current active mode.
-
-The mode :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>` is for raw IR,
-in which packets containing an unsigned int value describing an IR signal are
-read from the chardev.
-
-Alternatively, :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` can be available,
-in this mode scancodes which are either decoded by software decoders, or
-by hardware decoders. The :c:type:`rc_proto` member is set to the
-:ref:`IR protocol <Remote_controllers_Protocols>`
-used for transmission, and ``scancode`` to the decoded scancode,
-and the ``keycode`` set to the keycode or ``KEY_RESERVED``.
-
-
-Return Value
-============
-
-On success, the number of bytes read is returned. It is not an error if
-this number is smaller than the number of bytes requested, or the amount
-of data required for one frame.  On error, -1 is returned, and the ``errno``
-variable is set appropriately.

-Description
-===========
-
-Some receivers are equipped with special wide band receiver which is

-
-This might be useful of receivers that have otherwise narrow band receiver
-that prevents them to be used with some remotes. Wide band receiver might

-
-.. note::
-
-    Wide band receiver might be implictly enabled if you enable

-Arguments
-=========
-
-``fd``
-    File descriptor returned by ``open()``.
-
-``buf``
-    Buffer with data to be written
-
-``count``
-    Number of bytes at the buffer
-
-Description
-===========
-
-:ref:`write() <lirc-write>` writes up to ``count`` bytes to the device
-referenced by the file descriptor ``fd`` from the buffer starting at
-``buf``.
-
-The exact format of the data depends on what mode a driver is in, use
-:ref:`lirc_get_features` to get the supported modes and use
-:ref:`lirc_set_send_mode` set the mode.
-
-When in :ref:`LIRC_MODE_PULSE <lirc-mode-PULSE>` mode, the data written to
-the chardev is a pulse/space sequence of integer values. Pulses and spaces
-are only marked implicitly by their position. The data must start and end
-with a pulse, therefore, the data must always include an uneven number of
-samples. The write function blocks until the data has been transmitted
-by the hardware. If more data is provided than the hardware can send, the
-driver returns ``EINVAL``.
-
-When in :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` mode, one
-``struct lirc_scancode`` must be written to the chardev at a time, else
-``EINVAL`` is returned. Set the desired scancode in the ``scancode`` member,
-and the :ref:`IR protocol <Remote_controllers_Protocols>` in the
-:c:type:`rc_proto`: member. All other members must be
-set to 0, else ``EINVAL`` is returned. If there is no protocol encoder
-for the protocol or the scancode is not valid for the specified protocol,
-``EINVAL`` is returned. The write function blocks until the scancode
-is transmitted by the hardware.
-
-
-Return Value
-============
-
-On success, the number of bytes written is returned. It is not an error if
-this number is smaller than the number of bytes requested, or the amount
-of data required for one frame.  On error, -1 is returned, and the ``errno``
-variable is set appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.

-Introduction
-************
-
-Currently, most analog and digital devices have a Infrared input for
-remote controllers. Each manufacturer has their own type of control. It
-is not rare for the same manufacturer to ship different types of
-controls, depending on the device.
-
-A Remote Controller interface is mapped as a normal evdev/input
-interface, just like a keyboard or a mouse. So, it uses all ioctls
-already defined for any other input devices.
-
-However, remove controllers are more flexible than a normal input
-device, as the IR receiver (and/or transmitter) can be used in
-conjunction with a wide variety of different IR remotes.
-
-In order to allow flexibility, the Remote Controller subsystem allows
-controlling the RC-specific attributes via
-:ref:`the sysfs class nodes <remote_controllers_sysfs_nodes>`.

-========================
-
-Sets the scancode filter expected value.
-
-Use in combination with ``/sys/class/rc/rcN/filter_mask`` to set the
-expected value of the bits set in the filter mask. If the hardware
-supports it then scancodes which do not match the filter will be
-ignored. Otherwise the write will fail with an error.
-
-This value may be reset to 0 if the current protocol is altered.
-
-
-.. _sys_class_rc_rcN_filter_mask:
-
-/sys/class/rc/rcN/filter_mask
-=============================
-
-Sets the scancode filter mask of bits to compare. Use in combination
-with ``/sys/class/rc/rcN/filter`` to set the bits of the scancode which
-should be compared against the expected value. A value of 0 disables the
-filter to allow all valid scancodes to be processed.
-
-If the hardware supports it then scancodes which do not match the filter
-will be ignored. Otherwise the write will fail with an error.

-.. _sys_class_rc_rcN_wakeup_protocols:
-
-/sys/class/rc/rcN/wakeup_protocols
-==================================
-
-Reading this file returns a list of available protocols to use for the
-wakeup filter, something like::
-
-	rc-5 nec nec-x rc-6-0 rc-6-6a-24 [rc-6-6a-32] rc-6-mce
-
-Note that protocol variants are listed, so ``nec``, ``sony``, ``rc-5``, ``rc-6``
-have their different bit length encodings listed if available.
-
-Note that all protocol variants are listed.
-
-The enabled wakeup protocol is shown in [] brackets.
-
-Only one protocol can be selected at a time.
-
-Writing "proto" will use "proto" for wakeup events.
-
-Writing "none" will disable wakeup.
-
-Write fails with ``EINVAL`` if an invalid protocol combination or unknown
-protocol name is used, or if wakeup is not supported by the hardware.
-
-
-.. _sys_class_rc_rcN_wakeup_filter:
-
-/sys/class/rc/rcN/wakeup_filter
-===============================
-
-Sets the scancode wakeup filter expected value. Use in combination with
-``/sys/class/rc/rcN/wakeup_filter_mask`` to set the expected value of
-the bits set in the wakeup filter mask to trigger a system wake event.
-
-If the hardware supports it and wakeup_filter_mask is not 0 then
-scancodes which match the filter will wake the system from e.g. suspend
-to RAM or power off. Otherwise the write will fail with an error.
-
-This value may be reset to 0 if the wakeup protocol is altered.
-
-
-.. _sys_class_rc_rcN_wakeup_filter_mask:

-Remote controller tables
-************************
-
-Unfortunately, for several years, there was no effort to create uniform
-IR keycodes for different devices. This caused the same IR keyname to be
-mapped completely differently on different IR devices. This resulted
-that the same IR keyname to be mapped completely different on different
-IR's. Due to that, V4L2 API now specifies a standard for mapping Media
-keys on IR.
-
-This standard should be used by both V4L/DVB drivers and userspace
-applications
-
-The modules register the remote as keyboard within the linux input
-layer. This means that the IR key strokes will look like normal keyboard
-key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event
-devices (CONFIG_INPUT_EVDEV) it is possible for applications to access
-the remote via /dev/input/event devices.

-Application Priority
-********************
-
-When multiple applications share a device it may be desirable to assign
-them different priorities. Contrary to the traditional "rm -rf /" school
-of thought, a video recording application could for example block other
-applications from changing video controls or switching the current TV
-channel. Another objective is to permit low priority applications
-working in background, which can be preempted by user controlled
-applications and automatically regain control of the device at a later
-time.
-
-Since these features cannot be implemented entirely in user space V4L2
-defines the :ref:`VIDIOC_G_PRIORITY <VIDIOC_G_PRIORITY>` and
-:ref:`VIDIOC_S_PRIORITY <VIDIOC_G_PRIORITY>` ioctls to request and
-query the access priority associate with a file descriptor. Opening a
-device assigns a medium priority, compatible with earlier versions of
-V4L2 and drivers not supporting these ioctls. Applications requiring a
-different priority will usually call :ref:`VIDIOC_S_PRIORITY
-<VIDIOC_G_PRIORITY>` after verifying the device with the
-:ref:`VIDIOC_QUERYCAP` ioctl.
-
-Ioctls changing driver properties, such as
-:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>`, return an ``EBUSY`` error code
-after another application obtained higher priority.

-************************
-Audio Inputs and Outputs
-************************
-
-Audio inputs and outputs are physical connectors of a device. Video
-capture devices have inputs, output devices have outputs, zero or more
-each. Radio devices have no audio inputs or outputs. They have exactly
-one tuner which in fact *is* an audio source, but this API associates
-tuners with video inputs or outputs only, and radio devices have none of
-these. [#f1]_ A connector on a TV card to loop back the received audio
-signal to a sound card is not considered an audio output.
-
-Audio and video inputs and outputs are associated. Selecting a video
-source also selects an audio source. This is most evident when the video
-and audio source is a tuner. Further audio connectors can combine with
-more than one video input or output. Assumed two composite video inputs
-and two audio inputs exist, there may be up to four valid combinations.
-The relation of video and audio connectors is defined in the
-``audioset`` field of the respective struct
-:c:type:`v4l2_input` or struct
-:c:type:`v4l2_output`, where each bit represents the index
-number, starting at zero, of one audio input or output.
-
-To learn about the number and attributes of the available inputs and
-outputs applications can enumerate them with the
-:ref:`VIDIOC_ENUMAUDIO` and
-:ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` ioctl, respectively.
-The struct :c:type:`v4l2_audio` returned by the
-:ref:`VIDIOC_ENUMAUDIO` ioctl also contains signal
-status information applicable when the current audio input is queried.
-
-The :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
-:ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` ioctls report the current
-audio input and output, respectively.
-
-.. note::
-
-   Note that, unlike :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
-   :ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` these ioctls return a
-   structure as :ref:`VIDIOC_ENUMAUDIO` and
-   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` do, not just an index.
-
-To select an audio input and change its properties applications call the
-:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` ioctl. To select an audio
-output (which presently has no changeable properties) applications call
-the :ref:`VIDIOC_S_AUDOUT <VIDIOC_G_AUDOUT>` ioctl.
-
-Drivers must implement all audio input ioctls when the device has
-multiple selectable audio inputs, all audio output ioctls when the
-device has multiple selectable audio outputs. When the device has any
-audio inputs or outputs the driver must set the ``V4L2_CAP_AUDIO`` flag
-in the struct :c:type:`v4l2_capability` returned by
-the :ref:`VIDIOC_QUERYCAP` ioctl.
-
-
-Example: Information about the current audio input
-==================================================
-
-.. code-block:: c
-
-    struct v4l2_audio audio;
-
-    memset(&audio, 0, sizeof(audio));
-
-    if (-1 == ioctl(fd, VIDIOC_G_AUDIO, &audio)) {
-	perror("VIDIOC_G_AUDIO");
-	exit(EXIT_FAILURE);
-    }
-
-    printf("Current input: %s\\n", audio.name);
-
-
-Example: Switching to the first audio input
-===========================================
-
-.. code-block:: c
-
-    struct v4l2_audio audio;
-
-    memset(&audio, 0, sizeof(audio)); /* clear audio.mode, audio.reserved */
-
-    audio.index = 0;
-
-    if (-1 == ioctl(fd, VIDIOC_S_AUDIO, &audio)) {
-	perror("VIDIOC_S_AUDIO");
-	exit(EXIT_FAILURE);
-    }
-
-.. [#f1]
-   Actually struct :c:type:`v4l2_audio` ought to have a
-   ``tuner`` field like struct :c:type:`v4l2_input`, not
-   only making the API more consistent but also permitting radio devices
-   with multiple tuners.

-Buffers
-*******
-
-A buffer contains data exchanged by application and driver using one of
-the Streaming I/O methods. In the multi-planar API, the data is held in
-planes, while the buffer structure acts as a container for the planes.
-Only pointers to buffers (planes) are exchanged, the data itself is not
-copied. These pointers, together with meta-information like timestamps
-or field parity, are stored in a struct :c:type:`v4l2_buffer`,
-argument to the :ref:`VIDIOC_QUERYBUF`,
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` and
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. In the multi-planar API,
-some plane-specific members of struct :c:type:`v4l2_buffer`,
-such as pointers and sizes for each plane, are stored in struct
-struct :c:type:`v4l2_plane` instead. In that case, struct
-struct :c:type:`v4l2_buffer` contains an array of plane structures.
-
-Dequeued video buffers come with timestamps. The driver decides at which
-part of the frame and with which clock the timestamp is taken. Please
-see flags in the masks ``V4L2_BUF_FLAG_TIMESTAMP_MASK`` and
-``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` in :ref:`buffer-flags`. These flags
-are always valid and constant across all buffers during the whole video
-stream. Changes in these flags may take place as a side effect of
-:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` or
-:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` however. The
-``V4L2_BUF_FLAG_TIMESTAMP_COPY`` timestamp type which is used by e.g. on
-mem-to-mem devices is an exception to the rule: the timestamp source
-flags are copied from the OUTPUT video buffer to the CAPTURE video
-buffer.
-
-
-Interactions between formats, controls and buffers
-==================================================
-
-V4L2 exposes parameters that influence the buffer size, or the way data is
-laid out in the buffer. Those parameters are exposed through both formats and
-controls. One example of such a control is the ``V4L2_CID_ROTATE`` control
-that modifies the direction in which pixels are stored in the buffer, as well
-as the buffer size when the selected format includes padding at the end of
-lines.
-
-The set of information needed to interpret the content of a buffer (e.g. the
-pixel format, the line stride, the tiling orientation or the rotation) is
-collectively referred to in the rest of this section as the buffer layout.
-
-Controls that can modify the buffer layout shall set the
-``V4L2_CTRL_FLAG_MODIFY_LAYOUT`` flag.
-
-Modifying formats or controls that influence the buffer size or layout require
-the stream to be stopped. Any attempt at such a modification while the stream
-is active shall cause the ioctl setting the format or the control to return
-the ``EBUSY`` error code. In that case drivers shall also set the
-``V4L2_CTRL_FLAG_GRABBED`` flag when calling
-:c:func:`VIDIOC_QUERYCTRL` or :c:func:`VIDIOC_QUERY_EXT_CTRL` for such a
-control while the stream is active.
-
-.. note::
-
-   The :c:func:`VIDIOC_S_SELECTION` ioctl can, depending on the hardware (for
-   instance if the device doesn't include a scaler), modify the format in
-   addition to the selection rectangle. Similarly, the
-   :c:func:`VIDIOC_S_INPUT`, :c:func:`VIDIOC_S_OUTPUT`, :c:func:`VIDIOC_S_STD`
-   and :c:func:`VIDIOC_S_DV_TIMINGS` ioctls can also modify the format and
-   selection rectangles. When those ioctls result in a buffer size or layout
-   change, drivers shall handle that condition as they would handle it in the
-   :c:func:`VIDIOC_S_FMT` ioctl in all cases described in this section.
-
-Controls that only influence the buffer layout can be modified at any time
-when the stream is stopped. As they don't influence the buffer size, no
-special handling is needed to synchronize those controls with buffer
-allocation and the ``V4L2_CTRL_FLAG_GRABBED`` flag is cleared once the
-stream is stopped.
-
-Formats and controls that influence the buffer size interact with buffer
-allocation. The simplest way to handle this is for drivers to always require
-buffers to be reallocated in order to change those formats or controls. In
-that case, to perform such changes, userspace applications shall first stop
-the video stream with the :c:func:`VIDIOC_STREAMOFF` ioctl if it is running
-and free all buffers with the :c:func:`VIDIOC_REQBUFS` ioctl if they are
-allocated. After freeing all buffers the ``V4L2_CTRL_FLAG_GRABBED`` flag
-for controls is cleared. The format or controls can then be modified, and
-buffers shall then be reallocated and the stream restarted. A typical ioctl
-sequence is
-
- #. VIDIOC_STREAMOFF
- #. VIDIOC_REQBUFS(0)
- #. VIDIOC_S_EXT_CTRLS
- #. VIDIOC_S_FMT
- #. VIDIOC_REQBUFS(n)
- #. VIDIOC_QBUF
- #. VIDIOC_STREAMON
-
-The second :c:func:`VIDIOC_REQBUFS` call will take the new format and control
-value into account to compute the buffer size to allocate. Applications can
-also retrieve the size by calling the :c:func:`VIDIOC_G_FMT` ioctl if needed.
-
-.. note::
-
-   The API doesn't mandate the above order for control (3.) and format (4.)
-   changes. Format and controls can be set in a different order, or even
-   interleaved, depending on the device and use case. For instance some
-   controls might behave differently for different pixel formats, in which
-   case the format might need to be set first.
-
-When reallocation is required, any attempt to modify format or controls that
-influences the buffer size while buffers are allocated shall cause the format
-or control set ioctl to return the ``EBUSY`` error. Any attempt to queue a
-buffer too small for the current format or controls shall cause the
-:c:func:`VIDIOC_QBUF` ioctl to return a ``EINVAL`` error.
-
-Buffer reallocation is an expensive operation. To avoid that cost, drivers can
-(and are encouraged to) allow format or controls that influence the buffer
-size to be changed with buffers allocated. In that case, a typical ioctl
-sequence to modify format and controls is
-
- #. VIDIOC_STREAMOFF
- #. VIDIOC_S_EXT_CTRLS
- #. VIDIOC_S_FMT
- #. VIDIOC_QBUF
- #. VIDIOC_STREAMON
-
-For this sequence to operate correctly, queued buffers need to be large enough
-for the new format or controls. Drivers shall return a ``ENOSPC`` error in
-response to format change (:c:func:`VIDIOC_S_FMT`) or control changes
-(:c:func:`VIDIOC_S_CTRL` or :c:func:`VIDIOC_S_EXT_CTRLS`) if buffers too small
-for the new format are currently queued. As a simplification, drivers are
-allowed to return a ``EBUSY`` error from these ioctls if any buffer is
-currently queued, without checking the queued buffers sizes.
-
-Additionally, drivers shall return a ``EINVAL`` error from the
-:c:func:`VIDIOC_QBUF` ioctl if the buffer being queued is too small for the
-current format or controls. Together, these requirements ensure that queued
-buffers will always be large enough for the configured format and controls.
-
-Userspace applications can query the buffer size required for a given format
-and controls by first setting the desired control values and then trying the
-desired format. The :c:func:`VIDIOC_TRY_FMT` ioctl will return the required
-buffer size.
-
- #. VIDIOC_S_EXT_CTRLS(x)
- #. VIDIOC_TRY_FMT()
- #. VIDIOC_S_EXT_CTRLS(y)
- #. VIDIOC_TRY_FMT()
-
-The :c:func:`VIDIOC_CREATE_BUFS` ioctl can then be used to allocate buffers
-based on the queried sizes (for instance by allocating a set of buffers large
-enough for all the desired formats and controls, or by allocating separate set
-of appropriately sized buffers for each use case).

-
-    * - __u32
-      - ``index``
-      - Number of the buffer, set by the application except when calling
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, then it is set by the
-	driver. This field can range from zero to the number of buffers
-	allocated with the :ref:`VIDIOC_REQBUFS` ioctl
-	(struct :c:type:`v4l2_requestbuffers`
-	``count``), plus any buffers allocated with
-	:ref:`VIDIOC_CREATE_BUFS` minus one.
-    * - __u32
-      - ``type``
-      - Type of the buffer, same as struct
-	:c:type:`v4l2_format` ``type`` or struct
-	:c:type:`v4l2_requestbuffers` ``type``, set
-	by the application. See :c:type:`v4l2_buf_type`
-    * - __u32
-      - ``bytesused``
-      - The number of bytes occupied by the data in the buffer. It depends
-	on the negotiated data format and may change with each buffer for
-	compressed variable size data like JPEG images. Drivers must set
-	this field when ``type`` refers to a capture stream, applications
-	when it refers to an output stream. If the application sets this
-	to 0 for an output stream, then ``bytesused`` will be set to the
-	size of the buffer (see the ``length`` field of this struct) by
-	the driver. For multiplanar formats this field is ignored and the
-	``planes`` pointer is used instead.
-    * - __u32
-      - ``flags``
-      - Flags set by the application or driver, see :ref:`buffer-flags`.
-    * - __u32
-      - ``field``
-      - Indicates the field order of the image in the buffer, see
-	:c:type:`v4l2_field`. This field is not used when the buffer
-	contains VBI data. Drivers must set it when ``type`` refers to a
-	capture stream, applications when it refers to an output stream.
-    * - struct timeval
-      - ``timestamp``
-      - For capture streams this is time when the first data byte was
-	captured, as returned by the :c:func:`clock_gettime()` function
-	for the relevant clock id; see ``V4L2_BUF_FLAG_TIMESTAMP_*`` in
-	:ref:`buffer-flags`. For output streams the driver stores the
-	time at which the last data byte was actually sent out in the
-	``timestamp`` field. This permits applications to monitor the
-	drift between the video and system clock. For output streams that
-	use ``V4L2_BUF_FLAG_TIMESTAMP_COPY`` the application has to fill
-	in the timestamp which will be copied by the driver to the capture
-	stream.
-    * - struct :c:type:`v4l2_timecode`
-      - ``timecode``
-      - When the ``V4L2_BUF_FLAG_TIMECODE`` flag is set in ``flags``, this
-	structure contains a frame timecode. In
-	:c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
-	bottom field contain the same timecode. Timecodes are intended to
-	help video editing and are typically recorded on video tapes, but
-	also embedded in compressed formats like MPEG. This field is
-	independent of the ``timestamp`` and ``sequence`` fields.
-    * - __u32
-      - ``sequence``
-      - Set by the driver, counting the frames (not fields!) in sequence.
-	This field is set for both input and output devices.
-    * - :cspan:`2`
-
-	In :c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
-	bottom field have the same sequence number. The count starts at
-	zero and includes dropped or repeated frames. A dropped frame was
-	received by an input device but could not be stored due to lack of
-	free buffer space. A repeated frame was displayed again by an
-	output device because the application did not pass new data in
-	time.
-
-	.. note::
-
-	   This may count the frames received e.g. over USB, without
-	   taking into account the frames dropped by the remote hardware due
-	   to limited compression throughput or bus bandwidth. These devices
-	   identify by not enumerating any video standards, see
-	   :ref:`standard`.
-
-    * - __u32
-      - ``memory``
-      - This field must be set by applications and/or drivers in
-	accordance with the selected I/O method. See :c:type:`v4l2_memory`

-	start of the device memory. The value is returned by the driver
-	and apart of serving as parameter to the
-	:ref:`mmap() <func-mmap>` function not useful for applications.
-	See :ref:`mmap` for details
-    * - unsigned long
-      - ``userptr``
-      - For the single-planar API and when ``memory`` is
-	``V4L2_MEMORY_USERPTR`` this is a pointer to the buffer (casted to
-	unsigned long type) in virtual memory, set by the application. See
-	:ref:`userp` for details.
-    * - struct v4l2_plane
-      - ``*planes``
-      - When using the multi-planar API, contains a userspace pointer to
-	an array of struct :c:type:`v4l2_plane`. The size of
-	the array should be put in the ``length`` field of this
-	struct :c:type:`v4l2_buffer` structure.
-    * - int
-      - ``fd``
-      - For the single-plane API and when ``memory`` is
-	``V4L2_MEMORY_DMABUF`` this is the file descriptor associated with
-	a DMABUF buffer.
-    * - }
-      -
-    * - __u32
-      - ``length``
-      - Size of the buffer (not the payload) in bytes for the
-	single-planar API. This is set by the driver based on the calls to
-	:ref:`VIDIOC_REQBUFS` and/or
-	:ref:`VIDIOC_CREATE_BUFS`. For the
-	multi-planar API the application sets this to the number of
-	elements in the ``planes`` array. The driver will fill in the
-	actual number of valid elements in that array.
-    * - __u32
-      - ``reserved2``
-      - A place holder for future extensions. Drivers and applications
-	must set this to 0.
-    * - __u32
-      - ``request_fd``
-      - The file descriptor of the request to queue the buffer to. If the flag
-        ``V4L2_BUF_FLAG_REQUEST_FD`` is set, then the buffer will be
-	queued to this request. If the flag is not set, then this field will
-	be ignored.
-
-	The ``V4L2_BUF_FLAG_REQUEST_FD`` flag and this field are only used by
-	:ref:`ioctl VIDIOC_QBUF <VIDIOC_QBUF>` and ignored by other ioctls that
-	take a :c:type:`v4l2_buffer` as argument.
-
-	Applications should not set ``V4L2_BUF_FLAG_REQUEST_FD`` for any ioctls
-	other than :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`.
-
-	If the device does not support requests, then ``EBADR`` will be returned.
-	If requests are supported but an invalid request file descriptor is
-	given, then ``EINVAL`` will be returned.

-
-    * .. _`V4L2-BUF-FLAG-MAPPED`:
-
-      - ``V4L2_BUF_FLAG_MAPPED``
-      - 0x00000001
-      - The buffer resides in device memory and has been mapped into the
-	application's address space, see :ref:`mmap` for details.
-	Drivers set or clear this flag when the
-	:ref:`VIDIOC_QUERYBUF`,
-	:ref:`VIDIOC_QBUF` or
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Set by the
-	driver.
-    * .. _`V4L2-BUF-FLAG-QUEUED`:
-
-      - ``V4L2_BUF_FLAG_QUEUED``
-      - 0x00000002
-      - Internally drivers maintain two buffer queues, an incoming and
-	outgoing queue. When this flag is set, the buffer is currently on
-	the incoming queue. It automatically moves to the outgoing queue
-	after the buffer has been filled (capture devices) or displayed
-	(output devices). Drivers set or clear this flag when the
-	``VIDIOC_QUERYBUF`` ioctl is called. After (successful) calling
-	the ``VIDIOC_QBUF``\ ioctl it is always set and after
-	``VIDIOC_DQBUF`` always cleared.
-    * .. _`V4L2-BUF-FLAG-DONE`:
-
-      - ``V4L2_BUF_FLAG_DONE``
-      - 0x00000004
-      - When this flag is set, the buffer is currently on the outgoing
-	queue, ready to be dequeued from the driver. Drivers set or clear
-	this flag when the ``VIDIOC_QUERYBUF`` ioctl is called. After
-	calling the ``VIDIOC_QBUF`` or ``VIDIOC_DQBUF`` it is always
-	cleared. Of course a buffer cannot be on both queues at the same
-	time, the ``V4L2_BUF_FLAG_QUEUED`` and ``V4L2_BUF_FLAG_DONE`` flag
-	are mutually exclusive. They can be both cleared however, then the
-	buffer is in "dequeued" state, in the application domain so to
-	say.
-    * .. _`V4L2-BUF-FLAG-ERROR`:
-
-      - ``V4L2_BUF_FLAG_ERROR``
-      - 0x00000040
-      - When this flag is set, the buffer has been dequeued successfully,
-	although the data might have been corrupted. This is recoverable,
-	streaming may continue as normal and the buffer may be reused
-	normally. Drivers set this flag when the ``VIDIOC_DQBUF`` ioctl is
-	called.
-    * .. _`V4L2-BUF-FLAG-IN-REQUEST`:
-
-      - ``V4L2_BUF_FLAG_IN_REQUEST``
-      - 0x00000080
-      - This buffer is part of a request that hasn't been queued yet.
-    * .. _`V4L2-BUF-FLAG-KEYFRAME`:
-
-      - ``V4L2_BUF_FLAG_KEYFRAME``
-      - 0x00000008
-      - Drivers set or clear this flag when calling the ``VIDIOC_DQBUF``
-	ioctl. It may be set by video capture devices when the buffer
-	contains a compressed image which is a key frame (or field), i. e.
-	can be decompressed on its own. Also known as an I-frame.
-	Applications can set this bit when ``type`` refers to an output
-	stream.
-    * .. _`V4L2-BUF-FLAG-PFRAME`:
-
-      - ``V4L2_BUF_FLAG_PFRAME``
-      - 0x00000010
-      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags predicted frames
-	or fields which contain only differences to a previous key frame.
-	Applications can set this bit when ``type`` refers to an output
-	stream.
-    * .. _`V4L2-BUF-FLAG-BFRAME`:
-
-      - ``V4L2_BUF_FLAG_BFRAME``
-      - 0x00000020
-      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional
-	predicted frame or field which contains only the differences
-	between the current frame and both the preceding and following key
-	frames to specify its content. Applications can set this bit when
-	``type`` refers to an output stream.
-    * .. _`V4L2-BUF-FLAG-TIMECODE`:
-
-      - ``V4L2_BUF_FLAG_TIMECODE``
-      - 0x00000100
-      - The ``timecode`` field is valid. Drivers set or clear this flag
-	when the ``VIDIOC_DQBUF`` ioctl is called. Applications can set
-	this bit and the corresponding ``timecode`` structure when
-	``type`` refers to an output stream.
-    * .. _`V4L2-BUF-FLAG-PREPARED`:
-
-      - ``V4L2_BUF_FLAG_PREPARED``
-      - 0x00000400
-      - The buffer has been prepared for I/O and can be queued by the
-	application. Drivers set or clear this flag when the
-	:ref:`VIDIOC_QUERYBUF`,
-	:ref:`VIDIOC_PREPARE_BUF <VIDIOC_QBUF>`,
-	:ref:`VIDIOC_QBUF` or
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called.
-    * .. _`V4L2-BUF-FLAG-NO-CACHE-INVALIDATE`:
-
-      - ``V4L2_BUF_FLAG_NO_CACHE_INVALIDATE``
-      - 0x00000800
-      - Caches do not have to be invalidated for this buffer. Typically
-	applications shall use this flag if the data captured in the
-	buffer is not going to be touched by the CPU, instead the buffer
-	will, probably, be passed on to a DMA-capable hardware unit for
-	further processing or output.
-    * .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
-
-      - ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
-      - 0x00001000
-      - Caches do not have to be cleaned for this buffer. Typically
-	applications shall use this flag for output buffers if the data in
-	this buffer has not been created by the CPU but by some
-	DMA-capable unit, in which case caches have not been used.
-    * .. _`V4L2-BUF-FLAG-M2M-HOLD-CAPTURE-BUF`:
-
-      - ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF``
-      - 0x00000200
-      - Only valid if ``V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF`` is
-	set. It is typically used with stateless decoders where multiple
-	output buffers each decode to a slice of the decoded frame.
-	Applications can set this flag when queueing the output buffer
-	to prevent the driver from dequeueing the capture buffer after
-	the output buffer has been decoded (i.e. the capture buffer is
-	'held'). If the timestamp of this output buffer differs from that
-	of the previous output buffer, then that indicates the start of a
-	new frame and the previously held capture buffer is dequeued.
-    * .. _`V4L2-BUF-FLAG-LAST`:
-
-      - ``V4L2_BUF_FLAG_LAST``
-      - 0x00100000
-      - Last buffer produced by the hardware. mem2mem codec drivers set
-	this flag on the capture queue for the last buffer when the
-	:ref:`VIDIOC_QUERYBUF` or
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
-	hardware limitations, the last buffer may be empty. In this case
-	the driver will set the ``bytesused`` field to 0, regardless of
-	the format. Any Any subsequent call to the
-	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
-	but return an ``EPIPE`` error code.
-    * .. _`V4L2-BUF-FLAG-REQUEST-FD`:
-
-      - ``V4L2_BUF_FLAG_REQUEST_FD``
-      - 0x00800000
-      - The ``request_fd`` field contains a valid file descriptor.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MASK`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_MASK``
-      - 0x0000e000
-      - Mask for timestamp types below. To test the timestamp type, mask
-	out bits not belonging to timestamp type by performing a logical
-	and operation with buffer flags and timestamp mask.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-UNKNOWN`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
-      - 0x00000000
-      - Unknown timestamp type. This type is used by drivers before Linux
-	3.9 and may be either monotonic (see below) or realtime (wall
-	clock). Monotonic clock has been favoured in embedded systems
-	whereas most of the drivers use the realtime clock. Either kinds
-	of timestamps are available in user space via
-	:c:func:`clock_gettime` using clock IDs ``CLOCK_MONOTONIC``
-	and ``CLOCK_REALTIME``, respectively.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
-      - 0x00002000
-      - The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``
-	clock. To access the same clock outside V4L2, use
-	:c:func:`clock_gettime`.
-    * .. _`V4L2-BUF-FLAG-TIMESTAMP-COPY`:
-
-      - ``V4L2_BUF_FLAG_TIMESTAMP_COPY``
-      - 0x00004000
-      - The CAPTURE buffer timestamp has been taken from the corresponding
-	OUTPUT buffer. This flag applies only to mem2mem devices.
-    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-MASK`:
-
-      - ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK``
-      - 0x00070000
-      - Mask for timestamp sources below. The timestamp source defines the
-	point of time the timestamp is taken in relation to the frame.
-	Logical 'and' operation between the ``flags`` field and
-	``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` produces the value of the
-	timestamp source. Applications must set the timestamp source when
-	``type`` refers to an output stream and
-	``V4L2_BUF_FLAG_TIMESTAMP_COPY`` is set.
-    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-EOF`:
-
-      - ``V4L2_BUF_FLAG_TSTAMP_SRC_EOF``
-      - 0x00000000
-      - End Of Frame. The buffer timestamp has been taken when the last
-	pixel of the frame has been received or the last pixel of the
-	frame has been transmitted. In practice, software generated
-	timestamps will typically be read from the clock a small amount of
-	time after the last pixel has been received or transmitten,
-	depending on the system and other activity in it.
-    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-SOE`:
-
-      - ``V4L2_BUF_FLAG_TSTAMP_SRC_SOE``
-      - 0x00010000
-      - Start Of Exposure. The buffer timestamp has been taken when the
-	exposure of the frame has begun. This is only valid for the
-	``V4L2_BUF_TYPE_VIDEO_CAPTURE`` buffer type.

-****************************
-Defining Colorspaces in V4L2
-****************************
-
-In V4L2 colorspaces are defined by four values. The first is the
-colorspace identifier (enum :c:type:`v4l2_colorspace`)
-which defines the chromaticities, the default transfer function, the
-default Y'CbCr encoding and the default quantization method. The second
-is the transfer function identifier (enum
-:c:type:`v4l2_xfer_func`) to specify non-standard
-transfer functions. The third is the Y'CbCr encoding identifier (enum
-:c:type:`v4l2_ycbcr_encoding`) to specify
-non-standard Y'CbCr encodings and the fourth is the quantization
-identifier (enum :c:type:`v4l2_quantization`) to
-specify non-standard quantization methods. Most of the time only the
-colorspace field of struct :c:type:`v4l2_pix_format`
-or struct :c:type:`v4l2_pix_format_mplane`
-needs to be filled in.
-
-.. _hsv-colorspace:
-
-On :ref:`HSV formats <hsv-formats>` the *Hue* is defined as the angle on
-the cylindrical color representation. Usually this angle is measured in
-degrees, i.e. 0-360. When we map this angle value into 8 bits, there are
-two basic ways to do it: Divide the angular value by 2 (0-179), or use the
-whole range, 0-255, dividing the angular value by 1.41. The enum
-:c:type:`v4l2_hsv_encoding` specifies which encoding is used.
-
-.. note:: The default R'G'B' quantization is full range for all
-   colorspaces except for BT.2020 which uses limited range R'G'B'
-   quantization.

-
-Colorspace SMPTE 170M (V4L2_COLORSPACE_SMPTE170M)
-=================================================
-
-The :ref:`smpte170m` standard defines the colorspace used by NTSC and
-PAL and by SDTV in general. The default transfer function is
-``V4L2_XFER_FUNC_709``. The default Y'CbCr encoding is
-``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited
-range. The chromaticities of the primary colors and the white reference
-are:

-    * - White Reference (D65)
-      - 0.3127
-      - 0.3290
-
-
-The red, green and blue chromaticities are also often referred to as the
-SMPTE C set, so this colorspace is sometimes called SMPTE C as well.
-
-The transfer function defined for SMPTE 170M is the same as the one
-defined in Rec. 709.
-
-.. math::
-
-    L' = -1.099(-L)^{0.45} + 0.099 \text{, for } L \le-0.018
-
-    L' = 4.5L \text{, for } -0.018 < L < 0.018
-
-    L' = 1.099L^{0.45} - 0.099 \text{, for } L \ge 0.018
-
-Inverse Transfer function:
-
-.. math::
-
-    L = -\left( \frac{L' - 0.099}{-1.099} \right) ^{\frac{1}{0.45}} \text{, for } L' \le -0.081
-
-    L = \frac{L'}{4.5} \text{, for } -0.081 < L' < 0.081
-
-    L = \left(\frac{L' + 0.099}{1.099}\right)^{\frac{1}{0.45} } \text{, for } L' \ge 0.081
-
-The luminance (Y') and color difference (Cb and Cr) are obtained with
-the following ``V4L2_YCBCR_ENC_601`` encoding:
-
-.. math::
-
-    Y' = 0.2990R' + 0.5870G' + 0.1140B'
-
-    Cb = -0.1687R' - 0.3313G' + 0.5B'
-
-    Cr = 0.5R' - 0.4187G' - 0.0813B'
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5]. This conversion to Y'CbCr is identical to the one defined in
-the :ref:`itu601` standard and this colorspace is sometimes called
-BT.601 as well, even though BT.601 does not mention any color primaries.
-
-The default quantization is limited range, but full range is possible
-although rarely seen.
-
-
-.. _col-rec709:
-
-Colorspace Rec. 709 (V4L2_COLORSPACE_REC709)
-============================================
-
-The :ref:`itu709` standard defines the colorspace used by HDTV in
-general. The default transfer function is ``V4L2_XFER_FUNC_709``. The
-default Y'CbCr encoding is ``V4L2_YCBCR_ENC_709``. The default Y'CbCr
-quantization is limited range. The chromaticities of the primary colors
-and the white reference are:

-      - 0.3290
-
-
-The full name of this standard is Rec. ITU-R BT.709-5.
-
-Transfer function. Normally L is in the range [0…1], but for the
-extended gamut xvYCC encoding values outside that range are allowed.
-
-.. math::
-
-    L' = -1.099(-L)^{0.45} + 0.099 \text{, for } L \le -0.018
-
-    L' = 4.5L \text{, for } -0.018 < L < 0.018
-
-    L' = 1.099L^{0.45} - 0.099 \text{, for } L \ge 0.018
-
-Inverse Transfer function:
-
-.. math::
-
-    L = -\left( \frac{L' - 0.099}{-1.099} \right)^\frac{1}{0.45} \text{, for } L' \le -0.081
-
-    L = \frac{L'}{4.5}\text{, for } -0.081 < L' < 0.081
-
-    L = \left(\frac{L' + 0.099}{1.099}\right)^{\frac{1}{0.45} } \text{, for } L' \ge 0.081
-
-The luminance (Y') and color difference (Cb and Cr) are obtained with
-the following ``V4L2_YCBCR_ENC_709`` encoding:
-
-.. math::
-
-    Y' = 0.2126R' + 0.7152G' + 0.0722B'
-
-    Cb = -0.1146R' - 0.3854G' + 0.5B'
-
-    Cr = 0.5R' - 0.4542G' - 0.0458B'
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5].
-
-The default quantization is limited range, but full range is possible
-although rarely seen.
-
-The ``V4L2_YCBCR_ENC_709`` encoding described above is the default for
-this colorspace, but it can be overridden with ``V4L2_YCBCR_ENC_601``,
-in which case the BT.601 Y'CbCr encoding is used.
-
-Two additional extended gamut Y'CbCr encodings are also possible with
-this colorspace:
-
-The xvYCC 709 encoding (``V4L2_YCBCR_ENC_XV709``, :ref:`xvycc`) is
-similar to the Rec. 709 encoding, but it allows for R', G' and B' values
-that are outside the range [0…1]. The resulting Y', Cb and Cr values are
-scaled and offset according to the limited range formula:
-
-.. math::
-
-    Y' = \frac{219}{256} * (0.2126R' + 0.7152G' + 0.0722B') + \frac{16}{256}
-
-    Cb = \frac{224}{256} * (-0.1146R' - 0.3854G' + 0.5B')
-
-    Cr = \frac{224}{256} * (0.5R' - 0.4542G' - 0.0458B')
-
-The xvYCC 601 encoding (``V4L2_YCBCR_ENC_XV601``, :ref:`xvycc`) is
-similar to the BT.601 encoding, but it allows for R', G' and B' values
-that are outside the range [0…1]. The resulting Y', Cb and Cr values are
-scaled and offset according to the limited range formula:
-
-.. math::
-
-    Y' = \frac{219}{256} * (0.2990R' + 0.5870G' + 0.1140B') + \frac{16}{256}
-
-    Cb = \frac{224}{256} * (-0.1687R' - 0.3313G' + 0.5B')
-
-    Cr = \frac{224}{256} * (0.5R' - 0.4187G' - 0.0813B')
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5] and quantized without further scaling or offsets.
-The non-standard xvYCC 709 or xvYCC 601 encodings can be
-used by selecting ``V4L2_YCBCR_ENC_XV709`` or ``V4L2_YCBCR_ENC_XV601``.
-As seen by the xvYCC formulas these encodings always use limited range quantization,
-there is no full range variant. The whole point of these extended gamut encodings
-is that values outside the limited range are still valid, although they
-map to R', G' and B' values outside the [0…1] range and are therefore outside
-the Rec. 709 colorspace gamut.
-
-
-.. _col-srgb:
-
-Colorspace sRGB (V4L2_COLORSPACE_SRGB)
-======================================
-
-The :ref:`srgb` standard defines the colorspace used by most webcams
-and computer graphics. The default transfer function is
-``V4L2_XFER_FUNC_SRGB``. The default Y'CbCr encoding is
-``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited range.
-
-Note that the :ref:`sycc` standard specifies full range quantization,
-however all current capture hardware supported by the kernel convert
-R'G'B' to limited range Y'CbCr. So choosing full range as the default
-would break how applications interpret the quantization range.
-
-The chromaticities of the primary colors and the white reference are:
-

-    * - White Reference (D65)

-      - 0.3290
-
-
-These chromaticities are identical to the Rec. 709 colorspace.
-
-Transfer function. Note that negative values for L are only used by the
-Y'CbCr conversion.
-
-.. math::
-
-    L' = -1.055(-L)^{\frac{1}{2.4} } + 0.055\text{, for }L < -0.0031308
-
-    L' = 12.92L\text{, for }-0.0031308 \le L \le 0.0031308
-
-    L' = 1.055L ^{\frac{1}{2.4} } - 0.055\text{, for }0.0031308 < L \le 1
-
-Inverse Transfer function:
-
-.. math::
-
-    L = -((-L' + 0.055) / 1.055) ^{2.4}\text{, for }L' < -0.04045
-
-    L = L' / 12.92\text{, for }-0.04045 \le L' \le 0.04045
-
-    L = ((L' + 0.055) / 1.055) ^{2.4}\text{, for }L' > 0.04045
-
-The luminance (Y') and color difference (Cb and Cr) are obtained with
-the following ``V4L2_YCBCR_ENC_601`` encoding as defined by :ref:`sycc`:
-
-.. math::
-
-    Y' = 0.2990R' + 0.5870G' + 0.1140B'
-
-    Cb = -0.1687R' - 0.3313G' + 0.5B'
-
-    Cr = 0.5R' - 0.4187G' - 0.0813B'
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5]. This transform is identical to one defined in SMPTE
-170M/BT.601. The Y'CbCr quantization is limited range.

-.. _col-oprgb:
-
-Colorspace opRGB (V4L2_COLORSPACE_OPRGB)
-===============================================
-
-The :ref:`oprgb` standard defines the colorspace used by computer
-graphics that use the opRGB colorspace. The default transfer function is
-``V4L2_XFER_FUNC_OPRGB``. The default Y'CbCr encoding is
-``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited

-.. math::
-
-    Y' = 0.2990R' + 0.5870G' + 0.1140B'

-    Cb = -0.1687R' - 0.3313G' + 0.5B'
-
-    Cr = 0.5R' - 0.4187G' - 0.0813B'
-
-Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
-[-0.5…0.5]. This transform is identical to one defined in SMPTE
-170M/BT.601. The Y'CbCr quantization is limited range.

-Colorspace BT.2020 (V4L2_COLORSPACE_BT2020)
-===========================================
-
-The :ref:`itu2020` standard defines the colorspace used by Ultra-high
-definition television (UHDTV). The default transfer function is
-``V4L2_XFER_FUNC_709``. The default Y'CbCr encoding is
-``V4L2_YCBCR_ENC_BT2020``. The default R'G'B' quantization is limited

-    L' = 1.099L ^{0.45} - 0.099\text{, for } 0.018 \le L \le 1

-Inverse Transfer function:

-
-    L = \left( \frac{L' + 0.099}{1.099}\right) ^{\frac{1}{0.45} }\text{, for } L' \ge 0.081
-
-Please note that while Rec. 709 is defined as the default transfer function
-by the :ref:`itu2020` standard, in practice this colorspace is often used
-with the :ref:`xf-smpte-2084`. In particular Ultra HD Blu-ray discs use

-Transfer Function SMPTE 2084 (V4L2_XFER_FUNC_SMPTE2084)
-=======================================================
-
-The :ref:`smpte2084` standard defines the transfer function used by
-High Dynamic Range content.
-
-Constants:
-    m1 = (2610 / 4096) / 4
-
-    m2 = (2523 / 4096) * 128
-
-    c1 = 3424 / 4096
-
-    c2 = (2413 / 4096) * 32
-
-    c3 = (2392 / 4096) * 32
-
-Transfer function:
-    L' = ((c1 + c2 * L\ :sup:`m1`) / (1 + c3 * L\ :sup:`m1`))\ :sup:`m2`
-
-Inverse Transfer function:
-    L = (max(L':sup:`1/m2` - c1, 0) / (c2 - c3 *
-    L'\ :sup:`1/m2`))\ :sup:`1/m1`
-
-Take care when converting between this transfer function and non-HDR transfer
-functions: the linear RGB values [0…1] of HDR content map to a luminance range
-of 0 to 10000 cd/m\ :sup:`2` whereas the linear RGB values of non-HDR (aka
-Standard Dynamic Range or SDR) map to a luminance range of 0 to 100 cd/m\ :sup:`2`.
-
-To go from SDR to HDR you will have to divide L by 100 first. To go in the other
-direction you will have to multiply L by 100. Of course, this clamps all
-luminance values over 100 cd/m\ :sup:`2` to 100 cd/m\ :sup:`2`.
-
-There are better methods, see e.g. :ref:`colimg` for more in-depth information
-about this.

-***********
-Colorspaces
-***********
-
-'Color' is a very complex concept and depends on physics, chemistry and
-biology. Just because you have three numbers that describe the 'red',
-'green' and 'blue' components of the color of a pixel does not mean that
-you can accurately display that color. A colorspace defines what it
-actually *means* to have an RGB value of e.g. (255, 0, 0). That is,
-which color should be reproduced on the screen in a perfectly calibrated
-environment.
-
-In order to do that we first need to have a good definition of color,
-i.e. some way to uniquely and unambiguously define a color so that
-someone else can reproduce it. Human color vision is trichromatic since
-the human eye has color receptors that are sensitive to three different
-wavelengths of light. Hence the need to use three numbers to describe
-color. Be glad you are not a mantis shrimp as those are sensitive to 12
-different wavelengths, so instead of RGB we would be using the
-ABCDEFGHIJKL colorspace...
-
-Color exists only in the eye and brain and is the result of how strongly
-color receptors are stimulated. This is based on the Spectral Power
-Distribution (SPD) which is a graph showing the intensity (radiant
-power) of the light at wavelengths covering the visible spectrum as it
-enters the eye. The science of colorimetry is about the relationship
-between the SPD and color as perceived by the human brain.
-
-Since the human eye has only three color receptors it is perfectly
-possible that different SPDs will result in the same stimulation of
-those receptors and are perceived as the same color, even though the SPD
-of the light is different.
-
-In the 1920s experiments were devised to determine the relationship
-between SPDs and the perceived color and that resulted in the CIE 1931
-standard that defines spectral weighting functions that model the
-perception of color. Specifically that standard defines functions that
-can take an SPD and calculate the stimulus for each color receptor.
-After some further mathematical transforms these stimuli are known as
-the *CIE XYZ tristimulus* values and these X, Y and Z values describe a
-color as perceived by a human unambiguously. These X, Y and Z values are
-all in the range [0…1].
-
-The Y value in the CIE XYZ colorspace corresponds to luminance. Often
-the CIE XYZ colorspace is transformed to the normalized CIE xyY
-colorspace:
-
-	x = X / (X + Y + Z)
-
-	y = Y / (X + Y + Z)
-
-The x and y values are the chromaticity coordinates and can be used to
-define a color without the luminance component Y. It is very confusing
-to have such similar names for these colorspaces. Just be aware that if
-colors are specified with lower case 'x' and 'y', then the CIE xyY
-colorspace is used. Upper case 'X' and 'Y' refer to the CIE XYZ
-colorspace. Also, y has nothing to do with luminance. Together x and y
-specify a color, and Y the luminance. That is really all you need to
-remember from a practical point of view. At the end of this section you
-will find reading resources that go into much more detail if you are
-interested.
-
-A monitor or TV will reproduce colors by emitting light at three
-different wavelengths, the combination of which will stimulate the color
-receptors in the eye and thus cause the perception of color.
-Historically these wavelengths were defined by the red, green and blue
-phosphors used in the displays. These *color primaries* are part of what
-defines a colorspace.
-
-Different display devices will have different primaries and some
-primaries are more suitable for some display technologies than others.
-This has resulted in a variety of colorspaces that are used for
-different display technologies or uses. To define a colorspace you need
-to define the three color primaries (these are typically defined as x, y
-chromaticity coordinates from the CIE xyY colorspace) but also the white
-reference: that is the color obtained when all three primaries are at
-maximum power. This determines the relative power or energy of the
-primaries. This is usually chosen to be close to daylight which has been
-defined as the CIE D65 Illuminant.
-
-To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
-Other colorspaces are defined by three chromaticity coordinates defined
-in the CIE xyY colorspace. Based on those a 3x3 matrix can be
-constructed that transforms CIE XYZ colors to colors in the new
-colorspace.
-
-Both the CIE XYZ and the RGB colorspace that are derived from the
-specific chromaticity primaries are linear colorspaces. But neither the
-eye, nor display technology is linear. Doubling the values of all
-components in the linear colorspace will not be perceived as twice the
-intensity of the color. So each colorspace also defines a transfer
-function that takes a linear color component value and transforms it to
-the non-linear component value, which is a closer match to the
-non-linear performance of both the eye and displays. Linear component
-values are denoted RGB, non-linear are denoted as R'G'B'. In general
-colors used in graphics are all R'G'B', except in openGL which uses
-linear RGB. Special care should be taken when dealing with openGL to
-provide linear RGB colors or to use the built-in openGL support to apply
-the inverse transfer function.
-
-The final piece that defines a colorspace is a function that transforms
-non-linear R'G'B' to non-linear Y'CbCr. This function is determined by
-the so-called luma coefficients. There may be multiple possible Y'CbCr
-encodings allowed for the same colorspace. Many encodings of color
-prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the
-human eye is more sensitive to differences in luminance than in color
-this encoding allows one to reduce the amount of color information
-compared to the luma data. Note that the luma (Y') is unrelated to the Y
-in the CIE XYZ colorspace. Also note that Y'CbCr is often called YCbCr
-or YUV even though these are strictly speaking wrong.
-
-Sometimes people confuse Y'CbCr as being a colorspace. This is not
-correct, it is just an encoding of an R'G'B' color into luma and chroma
-values. The underlying colorspace that is associated with the R'G'B'
-color is also associated with the Y'CbCr color.
-
-The final step is how the RGB, R'G'B' or Y'CbCr values are quantized.
-The CIE XYZ colorspace where X, Y and Z are in the range [0…1] describes
-all colors that humans can perceive, but the transform to another
-colorspace will produce colors that are outside the [0…1] range. Once
-clamped to the [0…1] range those colors can no longer be reproduced in
-that colorspace. This clamping is what reduces the extent or gamut of
-the colorspace. How the range of [0…1] is translated to integer values
-in the range of [0…255] (or higher, depending on the color depth) is
-called the quantization. This is *not* part of the colorspace
-definition. In practice RGB or R'G'B' values are full range, i.e. they
-use the full [0…255] range. Y'CbCr values on the other hand are limited
-range with Y' using [16…235] and Cb and Cr using [16…240].
-
-Unfortunately, in some cases limited range RGB is also used where the
-components use the range [16…235]. And full range Y'CbCr also exists
-using the [0…255] range.
-
-In order to correctly interpret a color you need to know the
-quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr
-encoding and the colorspace. From that information you can calculate the
-corresponding CIE XYZ color and map that again to whatever colorspace
-your display device uses.
-
-The colorspace definition itself consists of the three chromaticity
-primaries, the white reference chromaticity, a transfer function and the
-luma coefficients needed to transform R'G'B' to Y'CbCr. While some
-colorspace standards correctly define all four, quite often the
-colorspace standard only defines some, and you have to rely on other
-standards for the missing pieces. The fact that colorspaces are often a
-mix of different standards also led to very confusing naming conventions
-where the name of a standard was used to name a colorspace when in fact
-that standard was part of various other colorspaces as well.
-
-If you want to read more about colors and colorspaces, then the
-following resources are useful: :ref:`poynton` is a good practical
-book for video engineers, :ref:`colimg` has a much broader scope and
-describes many more aspects of color (physics, chemistry, biology,
-etc.). The
-`http://www.brucelindbloom.com <http://www.brucelindbloom.com>`__
-website is an excellent resource, especially with respect to the
-mathematics behind colorspace conversions. The wikipedia
-`CIE 1931 colorspace <http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space>`__
-article is also very useful.

-Programming a V4L2 device consists of these steps:
-
--  Opening the device
-
--  Changing device properties, selecting a video and audio input, video
-   standard, picture brightness a. o.
-
--  Negotiating a data format
-
--  Negotiating an input/output method
-
--  The actual input/output loop
-
--  Closing the device
-
-In practice most steps are optional and can be executed out of order. It
-depends on the V4L2 device type, you can read about the details in
-:ref:`devices`. In this chapter we will discuss the basic concepts
-applicable to all devices.

-
-*************
-User Controls
-*************
-
-Devices typically have a number of user-settable controls such as
-brightness, saturation and so on, which would be presented to the user
-on a graphical user interface. But, different devices will have
-different controls available, and furthermore, the range of possible
-values, and the default value will vary from device to device. The
-control ioctls provide the information and a mechanism to create a nice
-user interface for these controls that will work correctly with any
-device.
-
-All controls are accessed using an ID value. V4L2 defines several IDs
-for specific purposes. Drivers can also implement their own custom
-controls using ``V4L2_CID_PRIVATE_BASE``  [#f1]_ and higher values. The
-pre-defined control IDs have the prefix ``V4L2_CID_``, and are listed in
-:ref:`control-id`. The ID is used when querying the attributes of a
-control, and when getting or setting the current value.
-
-Generally applications should present controls to the user without
-assumptions about their purpose. Each control comes with a name string
-the user is supposed to understand. When the purpose is non-intuitive
-the driver writer should provide a user manual, a user interface plug-in
-or a driver specific panel application. Predefined IDs were introduced
-to change a few controls programmatically, for example to mute a device
-during a channel switch.
-
-Drivers may enumerate different controls after switching the current
-video input or output, tuner or modulator, or audio input or output.
-Different in the sense of other bounds, another default and current
-value, step size or other menu items. A control with a certain *custom*
-ID can also change name and type.
-
-If a control is not applicable to the current configuration of the
-device (for example, it doesn't apply to the current video input)
-drivers set the ``V4L2_CTRL_FLAG_INACTIVE`` flag.
-
-Control values are stored globally, they do not change when switching
-except to stay within the reported bounds. They also do not change e. g.
-when the device is opened or closed, when the tuner radio frequency is
-changed or generally never without application request.
-
-V4L2 specifies an event mechanism to notify applications when controls
-change value (see
-:ref:`VIDIOC_SUBSCRIBE_EVENT`, event
-``V4L2_EVENT_CTRL``), panel applications might want to make use of that
-in order to always reflect the correct control value.
-
-All controls use machine endianness.
-
-
-.. _control-id:
-
-Control IDs
-===========
-
-``V4L2_CID_BASE``
-    First predefined ID, equal to ``V4L2_CID_BRIGHTNESS``.
-
-``V4L2_CID_USER_BASE``
-    Synonym of ``V4L2_CID_BASE``.
-
-``V4L2_CID_BRIGHTNESS`` ``(integer)``
-    Picture brightness, or more precisely, the black level.
-
-``V4L2_CID_CONTRAST`` ``(integer)``
-    Picture contrast or luma gain.
-
-``V4L2_CID_SATURATION`` ``(integer)``
-    Picture color saturation or chroma gain.
-
-``V4L2_CID_HUE`` ``(integer)``
-    Hue or color balance.
-
-``V4L2_CID_AUDIO_VOLUME`` ``(integer)``
-    Overall audio volume. Note some drivers also provide an OSS or ALSA
-    mixer interface.
-
-``V4L2_CID_AUDIO_BALANCE`` ``(integer)``
-    Audio stereo balance. Minimum corresponds to all the way left,
-    maximum to right.
-
-``V4L2_CID_AUDIO_BASS`` ``(integer)``
-    Audio bass adjustment.
-
-``V4L2_CID_AUDIO_TREBLE`` ``(integer)``
-    Audio treble adjustment.
-
-``V4L2_CID_AUDIO_MUTE`` ``(boolean)``
-    Mute audio, i. e. set the volume to zero, however without affecting
-    ``V4L2_CID_AUDIO_VOLUME``. Like ALSA drivers, V4L2 drivers must mute
-    at load time to avoid excessive noise. Actually the entire device
-    should be reset to a low power consumption state.
-
-``V4L2_CID_AUDIO_LOUDNESS`` ``(boolean)``
-    Loudness mode (bass boost).
-
-``V4L2_CID_BLACK_LEVEL`` ``(integer)``
-    Another name for brightness (not a synonym of
-    ``V4L2_CID_BRIGHTNESS``). This control is deprecated and should not
-    be used in new drivers and applications.
-
-``V4L2_CID_AUTO_WHITE_BALANCE`` ``(boolean)``
-    Automatic white balance (cameras).
-
-``V4L2_CID_DO_WHITE_BALANCE`` ``(button)``
-    This is an action control. When set (the value is ignored), the
-    device will do a white balance and then hold the current setting.
-    Contrast this with the boolean ``V4L2_CID_AUTO_WHITE_BALANCE``,
-    which, when activated, keeps adjusting the white balance.
-
-``V4L2_CID_RED_BALANCE`` ``(integer)``
-    Red chroma balance.
-
-``V4L2_CID_BLUE_BALANCE`` ``(integer)``
-    Blue chroma balance.
-
-``V4L2_CID_GAMMA`` ``(integer)``
-    Gamma adjust.
-
-``V4L2_CID_WHITENESS`` ``(integer)``
-    Whiteness for grey-scale devices. This is a synonym for
-    ``V4L2_CID_GAMMA``. This control is deprecated and should not be
-    used in new drivers and applications.
-
-``V4L2_CID_EXPOSURE`` ``(integer)``
-    Exposure (cameras). [Unit?]
-
-``V4L2_CID_AUTOGAIN`` ``(boolean)``
-    Automatic gain/exposure control.
-
-``V4L2_CID_GAIN`` ``(integer)``
-    Gain control.
-
-    Primarily used to control gain on e.g. TV tuners but also on
-    webcams. Most devices control only digital gain with this control
-    but on some this could include analogue gain as well. Devices that
-    recognise the difference between digital and analogue gain use
-    controls ``V4L2_CID_DIGITAL_GAIN`` and ``V4L2_CID_ANALOGUE_GAIN``.
-
-``V4L2_CID_HFLIP`` ``(boolean)``
-    Mirror the picture horizontally.
-
-``V4L2_CID_VFLIP`` ``(boolean)``
-    Mirror the picture vertically.
-
-.. _v4l2-power-line-frequency:
-
-``V4L2_CID_POWER_LINE_FREQUENCY`` ``(enum)``
-    Enables a power line frequency filter to avoid flicker. Possible
-    values for ``enum v4l2_power_line_frequency`` are:
-    ``V4L2_CID_POWER_LINE_FREQUENCY_DISABLED`` (0),
-    ``V4L2_CID_POWER_LINE_FREQUENCY_50HZ`` (1),
-    ``V4L2_CID_POWER_LINE_FREQUENCY_60HZ`` (2) and
-    ``V4L2_CID_POWER_LINE_FREQUENCY_AUTO`` (3).
-
-``V4L2_CID_HUE_AUTO`` ``(boolean)``
-    Enables automatic hue control by the device. The effect of setting
-    ``V4L2_CID_HUE`` while automatic hue control is enabled is
-    undefined, drivers should ignore such request.
-
-``V4L2_CID_WHITE_BALANCE_TEMPERATURE`` ``(integer)``
-    This control specifies the white balance settings as a color
-    temperature in Kelvin. A driver should have a minimum of 2800
-    (incandescent) to 6500 (daylight). For more information about color
-    temperature see
-    `Wikipedia <http://en.wikipedia.org/wiki/Color_temperature>`__.
-
-``V4L2_CID_SHARPNESS`` ``(integer)``
-    Adjusts the sharpness filters in a camera. The minimum value
-    disables the filters, higher values give a sharper picture.
-
-``V4L2_CID_BACKLIGHT_COMPENSATION`` ``(integer)``
-    Adjusts the backlight compensation in a camera. The minimum value
-    disables backlight compensation.
-
-``V4L2_CID_CHROMA_AGC`` ``(boolean)``
-    Chroma automatic gain control.
-
-``V4L2_CID_CHROMA_GAIN`` ``(integer)``

-``V4L2_CID_COLOR_KILLER`` ``(boolean)``
-    Enable the color killer (i. e. force a black & white image in case
-    of a weak video signal).
-
-.. _v4l2-colorfx:
-
-``V4L2_CID_COLORFX`` ``(enum)``
-    Selects a color effect. The following values are defined:
-
-
-
-.. tabularcolumns:: |p{5.5cm}|p{12cm}|
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-    :widths: 11 24
-
-    * - ``V4L2_COLORFX_NONE``

-    * - ``V4L2_COLORFX_SKY_BLUE``
-      - Sky blue.
-    * - ``V4L2_COLORFX_SOLARIZATION``
-      - Solarization, the image is partially reversed in tone, only color
-	values above or below a certain threshold are inverted.
-    * - ``V4L2_COLORFX_SILHOUETTE``
-      - Silhouette (outline).
-    * - ``V4L2_COLORFX_VIVID``
-      - Vivid colors.
-    * - ``V4L2_COLORFX_SET_CBCR``
-      - The Cb and Cr chroma components are replaced by fixed coefficients
-	determined by ``V4L2_CID_COLORFX_CBCR`` control.
-
-
-
-``V4L2_CID_COLORFX_CBCR`` ``(integer)``
-    Determines the Cb and Cr coefficients for ``V4L2_COLORFX_SET_CBCR``
-    color effect. Bits [7:0] of the supplied 32 bit value are
-    interpreted as Cr component, bits [15:8] as Cb component and bits
-    [31:16] must be zero.
-
-``V4L2_CID_AUTOBRIGHTNESS`` ``(boolean)``
-    Enable Automatic Brightness.
-
-``V4L2_CID_ROTATE`` ``(integer)``
-    Rotates the image by specified angle. Common angles are 90, 270 and
-    180. Rotating the image to 90 and 270 will reverse the height and
-    width of the display window. It is necessary to set the new height
-    and width of the picture using the
-    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl according to the
-    rotation angle selected.
-
-``V4L2_CID_BG_COLOR`` ``(integer)``
-    Sets the background color on the current output device. Background
-    color needs to be specified in the RGB24 format. The supplied 32 bit
-    value is interpreted as bits 0-7 Red color information, bits 8-15
-    Green color information, bits 16-23 Blue color information and bits

-    microscope).
-
-``V4L2_CID_MIN_BUFFERS_FOR_CAPTURE`` ``(integer)``
-    This is a read-only control that can be read by the application and
-    used as a hint to determine the number of CAPTURE buffers to pass to
-    REQBUFS. The value is the minimum number of CAPTURE buffers that is
-    necessary for hardware to work.
-
-``V4L2_CID_MIN_BUFFERS_FOR_OUTPUT`` ``(integer)``
-    This is a read-only control that can be read by the application and

-    REQBUFS. The value is the minimum number of OUTPUT buffers that is
-    necessary for hardware to work.
-
-.. _v4l2-alpha-component:
-
-``V4L2_CID_ALPHA_COMPONENT`` ``(integer)``
-    Sets the alpha color component. When a capture device (or capture
-    queue of a mem-to-mem device) produces a frame format that includes
-    an alpha component (e.g.
-    :ref:`packed RGB image formats <pixfmt-rgb>`) and the alpha value
-    is not defined by the device or the mem-to-mem input data this
-    control lets you select the alpha component value of all pixels.
-    When an output device (or output queue of a mem-to-mem device)
-    consumes a frame format that doesn't include an alpha component and
-    the device supports alpha channel processing this control lets you
-    set the alpha component value of all pixels for further processing
-    in the device.
-
-``V4L2_CID_LASTP1``
-    End of the predefined control IDs (currently
-    ``V4L2_CID_ALPHA_COMPONENT`` + 1).
-
-``V4L2_CID_PRIVATE_BASE``
-    ID of the first custom (driver specific) control. Applications
-    depending on particular custom controls should check the driver name
-    and version, see :ref:`querycap`.
-
-Applications can enumerate the available controls with the
-:ref:`VIDIOC_QUERYCTRL` and
-:ref:`VIDIOC_QUERYMENU <VIDIOC_QUERYCTRL>` ioctls, get and set a
-control value with the :ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls. Drivers must implement
-``VIDIOC_QUERYCTRL``, ``VIDIOC_G_CTRL`` and ``VIDIOC_S_CTRL`` when the
-device has one or more controls, ``VIDIOC_QUERYMENU`` when it has one or
-more menu type controls.

-.. [#f1]
-   The use of ``V4L2_CID_PRIVATE_BASE`` is problematic because different
-   drivers may use the same ``V4L2_CID_PRIVATE_BASE`` ID for different
-   controls. This makes it hard to programmatically set such controls
-   since the meaning of the control with that ID is driver dependent. In
-   order to resolve this drivers use unique IDs and the
-   ``V4L2_CID_PRIVATE_BASE`` IDs are mapped to those unique IDs by the
-   kernel. Consider these ``V4L2_CID_PRIVATE_BASE`` IDs as aliases to
-   the real IDs.
-
-   Many applications today still use the ``V4L2_CID_PRIVATE_BASE`` IDs
-   instead of using :ref:`VIDIOC_QUERYCTRL` with
-   the ``V4L2_CTRL_FLAG_NEXT_CTRL`` flag to enumerate all IDs, so
-   support for ``V4L2_CID_PRIVATE_BASE`` is still around.

-*****************************************************
-Image Cropping, Insertion and Scaling -- the CROP API
-*****************************************************
-
-.. note::
-
-   The CROP API is mostly superseded by the newer :ref:`SELECTION API
-   <selection-api>`. The new API should be preferred in most cases,
-   with the exception of pixel aspect ratio detection, which is
-   implemented by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` and has no
-   equivalent in the SELECTION API. See :ref:`selection-vs-crop` for a
-   comparison of the two APIs.
-
-Some video capture devices can sample a subsection of the picture and
-shrink or enlarge it to an image of arbitrary size. We call these
-abilities cropping and scaling. Some video output devices can scale an
-image up or down and insert it at an arbitrary scan line and horizontal
-offset into a video signal.
-
-Applications can use the following API to select an area in the video
-signal, query the default area and the hardware limits.
-
-.. note::
-
-   Despite their name, the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`,
-   :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP
-   <VIDIOC_G_CROP>` ioctls apply to input as well as output devices.
-
-Scaling requires a source and a target. On a video capture or overlay
-device the source is the video signal, and the cropping ioctls determine
-the area actually sampled. The target are images read by the application
-or overlaid onto the graphics screen. Their size (and position for an
-overlay) is negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls.
-
-On a video output device the source are the images passed in by the
-application, and their size is again negotiated with the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctls, or may be encoded in a compressed video stream. The target is
-the video signal, and the cropping ioctls determine the area where the
-images are inserted.
-
-Source and target rectangles are defined even if the device does not
-support scaling or the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctls. Their size (and position
-where applicable) will be fixed in this case.
-
-.. note::
-
-   All capture and output devices that support the CROP or SELECTION
-   API will also support the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`
-   ioctl.

-    Image Cropping, Insertion and Scaling
-
-    The cropping, insertion and scaling process
-
-
-
-For capture devices the coordinates of the top left corner, width and
-height of the area which can be sampled is given by the ``bounds``
-substructure of the struct :c:type:`v4l2_cropcap` returned
-by the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` ioctl. To support a wide
-range of hardware this specification does not define an origin or units.
-However by convention drivers should horizontally count unscaled samples
-relative to 0H (the leading edge of the horizontal sync pulse, see
-:ref:`vbi-hsync`). Vertically ITU-R line numbers of the first field
-(see ITU R-525 line numbering for :ref:`525 lines <vbi-525>` and for
-:ref:`625 lines <vbi-625>`), multiplied by two if the driver
-can capture both fields.
-
-The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by struct
-:c:type:`v4l2_crop` using the same coordinate system as
-struct :c:type:`v4l2_cropcap`. Applications can use the
-:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>`
-ioctls to get and set this rectangle. It must lie completely within the
-capture boundaries and the driver may further adjust the requested size
-and/or position according to hardware limitations.
-
-Each capture device has a default source rectangle, given by the
-``defrect`` substructure of struct
-:c:type:`v4l2_cropcap`. The center of this rectangle
-shall align with the center of the active picture area of the video
-signal, and cover what the driver writer considers the complete picture.
-Drivers shall reset the source rectangle to the default when the driver
-is first loaded, but not later.
-
-For output devices these structures and ioctls are used accordingly,
-defining the *target* rectangle where the images will be inserted into
-the video signal.
-
-
-Scaling Adjustments
-===================
-
-Video hardware can have various cropping, insertion and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in horizontal and vertical
-direction. Also it may not support scaling at all. At the same time the
-struct :c:type:`v4l2_crop` rectangle may have to be aligned,
-and both the source and target rectangles may have arbitrary upper and
-lower size limits. In particular the maximum ``width`` and ``height`` in
-struct :c:type:`v4l2_crop` may be smaller than the struct
-:c:type:`v4l2_cropcap`. ``bounds`` area. Therefore, as
-usual, drivers are expected to adjust the requested parameters and
-return the actual values selected.
-
-Applications can change the source or the target rectangle first, as
-they may prefer a particular image size or a certain area in the video
-signal. If the driver has to adjust both to satisfy hardware
-limitations, the last requested rectangle shall take priority, and the
-driver should preferably adjust the opposite one. The
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl however shall not change
-the driver state and therefore only adjust the requested rectangle.
-
-Suppose scaling on a video capture device is restricted to a factor 1:1
-or 2:1 in either direction and the target image size must be a multiple
-of 16 × 16 pixels. The source cropping rectangle is set to defaults,
-which are also the upper limit in this example, of 640 × 400 pixels at
-offset 0, 0. An application requests an image size of 300 × 225 pixels,
-assuming video will be scaled down from the "full picture" accordingly.
-The driver sets the image size to the closest possible values 304 × 224,
-then chooses the cropping rectangle closest to the requested size, that
-is 608 × 224 (224 × 2:1 would exceed the limit 400). The offset 0, 0 is
-still valid, thus unmodified. Given the default cropping rectangle
-reported by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` the application can
-easily propose another offset to center the cropping rectangle.
-
-Now the application may insist on covering an area using a picture
-aspect ratio closer to the original request, so it asks for a cropping
-rectangle of 608 × 456 pixels. The present scaling factors limit
-cropping to 640 × 384, so the driver returns the cropping size 608 × 384
-and adjusts the image size to closest possible 304 × 192.
-
-
-Examples
-========
-
-Source and target rectangles shall remain unchanged across closing and
-reopening a device, such that piping data into or out of a device will
-work without special preparations. More advanced applications should
-ensure the parameters are suitable before starting I/O.
-

-
-***********************
-Video Capture Interface
-***********************
-
-Video capture devices sample an analog video signal and store the
-digitized images in memory. Today nearly all devices can capture at full
-25 or 30 frames/second. With this interface applications can control the
-capture process and move images from the driver into user space.
-
-Conventionally V4L2 video capture devices are accessed through character
-device special files named ``/dev/video`` and ``/dev/video0`` to
-``/dev/video63`` with major number 81 and minor numbers 0 to 63.
-``/dev/video`` is typically a symbolic link to the preferred video
-device.
-
-.. note:: The same device file names are used for video output devices.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the video capture interface set the
-``V4L2_CAP_VIDEO_CAPTURE`` or ``V4L2_CAP_VIDEO_CAPTURE_MPLANE`` flag in
-the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
-functions they may also support the :ref:`video overlay <overlay>`
-(``V4L2_CAP_VIDEO_OVERLAY``) and the :ref:`raw VBI capture <raw-vbi>`
-(``V4L2_CAP_VBI_CAPTURE``) interface. At least one of the read/write or
-streaming I/O methods must be supported. Tuners and audio inputs are
-optional.
-
-
-Supplemental Functions
-======================
-
-Video capture devices shall support :ref:`audio input <audio>`,
-:ref:`tuner`, :ref:`controls <control>`,
-:ref:`cropping and scaling <crop>` and
-:ref:`streaming parameter <streaming-par>` ioctls as needed. The
-:ref:`video input <video>` ioctls must be supported by all video
-capture devices.
-
-
-Image Format Negotiation
-========================
-
-The result of a capture operation is determined by cropping and image
-format parameters. The former select an area of the video picture to
-capture, the latter how images are stored in memory, i. e. in RGB or YUV
-format, the number of bits per pixel or width and height. Together they
-also define how images are scaled in the process.
-
-As usual these parameters are *not* reset at :ref:`open() <func-open>`
-time to permit Unix tool chains, programming a device and then reading
-from it as if it was a plain file. Well written V4L2 applications ensure
-they really get what they want, including cropping and scaling.
-
-Cropping initialization at minimum requires to reset the parameters to
-defaults. An example is given in :ref:`crop`.
-
-To query the current image format applications set the ``type`` field of
-a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
-``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and call the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
-structure. Drivers fill the struct
-:c:type:`v4l2_pix_format` ``pix`` or the struct
-:c:type:`v4l2_pix_format_mplane` ``pix_mp``
-member of the ``fmt`` union.
-
-To request different parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` as above and initialize all
-fields of the struct :c:type:`v4l2_pix_format`
-``vbi`` member of the ``fmt`` union, or better just modify the results
-of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl with a pointer to this structure. Drivers may adjust the
-parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-does.
-
-Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
-can be used to learn about hardware limitations without disabling I/O or
-possibly time consuming hardware preparations.
-
-The contents of struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_pix_format_mplane` are
-discussed in :ref:`pixfmt`. See also the specification of the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
-details. Video capture devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
-requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
-
-
-Reading Images
-==============
-
-A video capture device may support the :ref:`read() function <func-read>`
-and/or streaming (:ref:`memory mapping <func-mmap>` or
-:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

-***************
-Event Interface
-***************
-
-The V4L2 event interface provides a means for a user to get immediately
-notified on certain conditions taking place on a device. This might
-include start of frame or loss of signal events, for example. Changes in
-the value or state of a V4L2 control can also be reported through
-events.
-
-To receive events, the events the user is interested in first must be
-subscribed using the
-:ref:`VIDIOC_SUBSCRIBE_EVENT` ioctl. Once
-an event is subscribed, the events of subscribed types are dequeueable
-using the :ref:`VIDIOC_DQEVENT` ioctl. Events may be
-unsubscribed using VIDIOC_UNSUBSCRIBE_EVENT ioctl. The special event
-type V4L2_EVENT_ALL may be used to unsubscribe all the events the
-driver supports.
-
-The event subscriptions and event queues are specific to file handles.
-Subscribing an event on one file handle does not affect other file
-handles.
-
-The information on dequeueable events is obtained by using select or
-poll system calls on video devices. The V4L2 events use POLLPRI events
-on poll system call and exceptions on select system call.
-
-Starting with kernel 3.1 certain guarantees can be given with regards to
-events:
-
-1. Each subscribed event has its own internal dedicated event queue.
-   This means that flooding of one event type will not interfere with
-   other event types.
-
-2. If the internal event queue for a particular subscribed event becomes
-   full, then the oldest event in that queue will be dropped.
-
-3. Where applicable, certain event types can ensure that the payload of
-   the oldest event that is about to be dropped will be merged with the
-   payload of the next oldest event. Thus ensuring that no information
-   is lost, but only an intermediate step leading up to that
-   information. See the documentation for the event you want to
-   subscribe to whether this is applicable for that event or not.

-********************************
-Video Memory-To-Memory Interface
-********************************
-
-A V4L2 memory-to-memory device can compress, decompress, transform, or
-otherwise convert video data from one format into another format, in memory.
-Such memory-to-memory devices set the ``V4L2_CAP_VIDEO_M2M`` or
-``V4L2_CAP_VIDEO_M2M_MPLANE`` capability. Examples of memory-to-memory
-devices are codecs, scalers, deinterlacers or format converters (i.e.
-converting from YUV to RGB).
-
-A memory-to-memory video node acts just like a normal video node, but it
-supports both output (sending frames from memory to the hardware)
-and capture (receiving the processed frames from the hardware into
-memory) stream I/O. An application will have to setup the stream I/O for
-both sides and finally call :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-for both capture and output to start the hardware.
-
-Memory-to-memory devices function as a shared resource: you can
-open the video node multiple times, each application setting up their
-own properties that are local to the file handle, and each can use
-it independently from the others. The driver will arbitrate access to
-the hardware and reprogram it whenever another file handler gets access.
-This is different from the usual video node behavior where the video
-properties are global to the device (i.e. changing something through one
-file handle is visible through another file handle).
-
-One of the most common memory-to-memory device is the codec. Codecs
-are more complicated than most and require additional setup for
-their codec parameters. This is done through codec controls.
-See :ref:`mpeg-controls`. More details on how to use codec memory-to-memory
-devices are given in the following sections.

-Metadata Interface
-******************
-
-Metadata refers to any non-image data that supplements video frames with
-additional information. This may include statistics computed over the image,
-frame capture parameters supplied by the image source or device specific
-parameters for specifying how the device processes images. This interface is
-intended for transfer of metadata between the userspace and the hardware and
-control of that operation.
-
-The metadata interface is implemented on video device nodes. The device can be
-dedicated to metadata or can support both video and metadata as specified in its
-reported capabilities.
-
-Querying Capabilities
-=====================
-
-Device nodes supporting the metadata capture interface set the
-``V4L2_CAP_META_CAPTURE`` flag in the ``device_caps`` field of the
-:c:type:`v4l2_capability` structure returned by the :c:func:`VIDIOC_QUERYCAP`
-ioctl. That flag means the device can capture metadata to memory. Similarly,
-device nodes supporting metadata output interface set the
-``V4L2_CAP_META_OUTPUT`` flag in the ``device_caps`` field of
-:c:type:`v4l2_capability` structure. That flag means the device can read
-metadata from memory.
-
-At least one of the read/write or streaming I/O methods must be supported.
-
-
-Data Format Negotiation
-=======================
-
-The metadata device uses the :ref:`format` ioctls to select the capture format.
-The metadata buffer content format is bound to that selected format. In addition
-to the basic :ref:`format` ioctls, the :c:func:`VIDIOC_ENUM_FMT` ioctl must be
-supported as well.
-
-To use the :ref:`format` ioctls applications set the ``type`` field of the
-:c:type:`v4l2_format` structure to ``V4L2_BUF_TYPE_META_CAPTURE`` or to
-``V4L2_BUF_TYPE_META_OUTPUT`` and use the :c:type:`v4l2_meta_format` ``meta``
-member of the ``fmt`` union as needed per the desired operation. Both drivers
-and applications must set the remainder of the :c:type:`v4l2_format` structure
-to 0.

-Video Output Overlay Interface
-******************************
-
-**Also known as On-Screen Display (OSD)**
-
-Some video output devices can overlay a framebuffer image onto the
-outgoing video signal. Applications can set up such an overlay using
-this interface, which borrows structures and ioctls of the
-:ref:`Video Overlay <overlay>` interface.
-
-The OSD function is accessible through the same character special file
-as the :ref:`Video Output <capture>` function.
-
-.. note::
-
-   The default function of such a ``/dev/video`` device is video
-   capturing or output. The OSD function is only available after calling
-   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the *Video Output Overlay* interface set the
-``V4L2_CAP_VIDEO_OUTPUT_OVERLAY`` flag in the ``capabilities`` field of
-struct :c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl.
-
-
-Framebuffer
-===========
-
-Contrary to the *Video Overlay* interface the framebuffer is normally
-implemented on the TV card and not the graphics card. On Linux it is
-accessible as a framebuffer device (``/dev/fbN``). Given a V4L2 device,
-applications can find the corresponding framebuffer device by calling
-the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` ioctl. It returns, amongst
-other information, the physical address of the framebuffer in the
-``base`` field of struct :c:type:`v4l2_framebuffer`.
-The framebuffer device ioctl ``FBIOGET_FSCREENINFO`` returns the same
-address in the ``smem_start`` field of struct
-struct :c:type:`fb_fix_screeninfo`. The ``FBIOGET_FSCREENINFO``
-ioctl and struct :c:type:`fb_fix_screeninfo` are defined in
-the ``linux/fb.h`` header file.
-
-The width and height of the framebuffer depends on the current video
-standard. A V4L2 driver may reject attempts to change the video standard
-(or any other ioctl which would imply a framebuffer size change) with an
-``EBUSY`` error code until all applications closed the framebuffer device.
-
-Example: Finding a framebuffer device for OSD
----------------------------------------------
-
-.. code-block:: c
-
-    #include <linux/fb.h>
-
-    struct v4l2_framebuffer fbuf;
-    unsigned int i;
-    int fb_fd;
-
-    if (-1 == ioctl(fd, VIDIOC_G_FBUF, &fbuf)) {
-	perror("VIDIOC_G_FBUF");
-	exit(EXIT_FAILURE);
-    }
-
-    for (i = 0; i < 30; i++) {
-	char dev_name[16];
-	struct fb_fix_screeninfo si;
-
-	snprintf(dev_name, sizeof(dev_name), "/dev/fb%u", i);
-
-	fb_fd = open(dev_name, O_RDWR);
-	if (-1 == fb_fd) {
-	    switch (errno) {
-	    case ENOENT: /* no such file */
-	    case ENXIO:  /* no driver */
-		continue;
-
-	    default:
-		perror("open");
-		exit(EXIT_FAILURE);
-	    }
-	}
-
-	if (0 == ioctl(fb_fd, FBIOGET_FSCREENINFO, &si)) {
-	    if (si.smem_start == (unsigned long)fbuf.base)
-		break;
-	} else {
-	    /* Apparently not a framebuffer device. */
-	}
-
-	close(fb_fd);
-	fb_fd = -1;
-    }
-
-    /* fb_fd is the file descriptor of the framebuffer device
-       for the video output overlay, or -1 if no device was found. */
-
-
-Overlay Window and Scaling
-==========================
-
-The overlay is controlled by source and target rectangles. The source
-rectangle selects a subsection of the framebuffer image to be overlaid,
-the target rectangle an area in the outgoing video signal where the
-image will appear. Drivers may or may not support scaling, and arbitrary
-sizes and positions of these rectangles. Further drivers may support any
-(or none) of the clipping/blending methods defined for the
-:ref:`Video Overlay <overlay>` interface.
-
-A struct :c:type:`v4l2_window` defines the size of the
-source rectangle, its position in the framebuffer and the
-clipping/blending method to be used for the overlay. To get the current
-parameters applications set the ``type`` field of a struct
-:c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY`` and call the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
-struct :c:type:`v4l2_window` substructure named ``win``. It is not
-possible to retrieve a previously programmed clipping list or bitmap.
-
-To program the source rectangle applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY``, initialize the ``win``
-substructure and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-The driver adjusts the parameters against hardware limits and returns
-the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
-the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
-about driver capabilities without actually changing driver state. Unlike
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
-
-A struct :c:type:`v4l2_crop` defines the size and position
-of the target rectangle. The scaling factor of the overlay is implied by
-the width and height given in struct :c:type:`v4l2_window`
-and struct :c:type:`v4l2_crop`. The cropping API applies to
-*Video Output* and *Video Output Overlay* devices in the same way as to
-*Video Capture* and *Video Overlay* devices, merely reversing the
-direction of the data flow. For more information see :ref:`crop`.
-
-
-Enabling Overlay
-================
-
-There is no V4L2 ioctl to enable or disable the overlay, however the
-framebuffer interface of the driver may support the ``FBIOBLANK`` ioctl.

-**********************
-Video Output Interface
-**********************
-
-Video output devices encode stills or image sequences as analog video
-signal. With this interface applications can control the encoding
-process and move images from user space to the driver.
-
-Conventionally V4L2 video output devices are accessed through character
-device special files named ``/dev/video`` and ``/dev/video0`` to
-``/dev/video63`` with major number 81 and minor numbers 0 to 63.
-``/dev/video`` is typically a symbolic link to the preferred video
-device.
-
-.. note:: The same device file names are used also for video capture devices.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the video output interface set the
-``V4L2_CAP_VIDEO_OUTPUT`` or ``V4L2_CAP_VIDEO_OUTPUT_MPLANE`` flag in
-the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
-functions they may also support the :ref:`raw VBI output <raw-vbi>`
-(``V4L2_CAP_VBI_OUTPUT``) interface. At least one of the read/write or
-streaming I/O methods must be supported. Modulators and audio outputs
-are optional.
-
-
-Supplemental Functions
-======================
-
-Video output devices shall support :ref:`audio output <audio>`,
-:ref:`modulator <tuner>`, :ref:`controls <control>`,
-:ref:`cropping and scaling <crop>` and
-:ref:`streaming parameter <streaming-par>` ioctls as needed. The
-:ref:`video output <video>` ioctls must be supported by all video
-output devices.
-
-
-Image Format Negotiation
-========================
-
-The output is determined by cropping and image format parameters. The
-former select an area of the video picture where the image will appear,
-the latter how images are stored in memory, i. e. in RGB or YUV format,
-the number of bits per pixel or width and height. Together they also
-define how images are scaled in the process.
-
-As usual these parameters are *not* reset at :ref:`open() <func-open>`
-time to permit Unix tool chains, programming a device and then writing
-to it as if it was a plain file. Well written V4L2 applications ensure
-they really get what they want, including cropping and scaling.
-
-Cropping initialization at minimum requires to reset the parameters to
-defaults. An example is given in :ref:`crop`.
-
-To query the current image format applications set the ``type`` field of
-a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OUTPUT`` or ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``
-and call the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer
-to this structure. Drivers fill the struct
-:c:type:`v4l2_pix_format` ``pix`` or the struct
-:c:type:`v4l2_pix_format_mplane` ``pix_mp``
-member of the ``fmt`` union.
-
-To request different parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` as above and initialize all
-fields of the struct :c:type:`v4l2_pix_format`
-``vbi`` member of the ``fmt`` union, or better just modify the results
-of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl with a pointer to this structure. Drivers may adjust the
-parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-does.
-
-Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
-can be used to learn about hardware limitations without disabling I/O or
-possibly time consuming hardware preparations.
-
-The contents of struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_pix_format_mplane` are
-discussed in :ref:`pixfmt`. See also the specification of the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
-details. Video output devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
-and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
-requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
-
-
-Writing Images
-==============
-
-A video output device may support the :ref:`write() function <rw>`
-and/or streaming (:ref:`memory mapping <mmap>` or
-:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

-***********************
-Video Overlay Interface
-***********************
-
-**Also known as Framebuffer Overlay or Previewing.**
-
-Video overlay devices have the ability to genlock (TV-)video into the
-(VGA-)video signal of a graphics card, or to store captured images
-directly in video memory of a graphics card, typically with clipping.
-This can be considerable more efficient than capturing images and
-displaying them by other means. In the old days when only nuclear power
-plants needed cooling towers this used to be the only way to put live
-video into a window.
-
-Video overlay devices are accessed through the same character special
-files as :ref:`video capture <capture>` devices.
-
-.. note::
-
-   The default function of a ``/dev/video`` device is video
-   capturing. The overlay function is only available after calling
-   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-The driver may support simultaneous overlay and capturing using the
-read/write and streaming I/O methods. If so, operation at the nominal
-frame rate of the video standard is not guaranteed. Frames may be
-directed away from overlay to capture, or one field may be used for
-overlay and the other for capture if the capture parameters permit this.
-
-Applications should use different file descriptors for capturing and
-overlay. This must be supported by all drivers capable of simultaneous
-capturing and overlay. Optionally these drivers may also permit
-capturing and overlay with a single file descriptor for compatibility
-with V4L and earlier versions of V4L2. [#f1]_
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the video overlay interface set the
-``V4L2_CAP_VIDEO_OVERLAY`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. The overlay I/O
-method specified below must be supported. Tuners and audio inputs are
-optional.
-
-
-Supplemental Functions
-======================
-
-Video overlay devices shall support :ref:`audio input <audio>`,
-:ref:`tuner`, :ref:`controls <control>`,
-:ref:`cropping and scaling <crop>` and
-:ref:`streaming parameter <streaming-par>` ioctls as needed. The
-:ref:`video input <video>` and :ref:`video standard <standard>`
-ioctls must be supported by all video overlay devices.
-
-
-Setup
-=====
-
-Before overlay can commence applications must program the driver with
-frame buffer parameters, namely the address and size of the frame buffer
-and the image format, for example RGB 5:6:5. The
-:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
-:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls are available to get and
-set these parameters, respectively. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is
-privileged because it allows to set up DMA into physical memory,
-bypassing the memory protection mechanisms of the kernel. Only the
-superuser can change the frame buffer address and size. Users are not
-supposed to run TV applications as root or with SUID bit set. A small
-helper application with suitable privileges should query the graphics
-system and program the V4L2 driver at the appropriate time.
-
-Some devices add the video overlay to the output signal of the graphics
-card. In this case the frame buffer is not modified by the video device,
-and the frame buffer address and pixel format are not needed by the
-driver. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is not privileged. An application
-can check for this type of device by calling the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-ioctl.
-
-A driver may support any (or none) of five clipping/blending methods:
-
-1. Chroma-keying displays the overlaid image only where pixels in the
-   primary graphics surface assume a certain color.
-
-2. A bitmap can be specified where each bit corresponds to a pixel in
-   the overlaid image. When the bit is set, the corresponding video
-   pixel is displayed, otherwise a pixel of the graphics surface.
-
-3. A list of clipping rectangles can be specified. In these regions *no*
-   video is displayed, so the graphics surface can be seen here.
-
-4. The framebuffer has an alpha channel that can be used to clip or
-   blend the framebuffer with the video.
-
-5. A global alpha value can be specified to blend the framebuffer
-   contents with video images.
-
-When simultaneous capturing and overlay is supported and the hardware
-prohibits different image and frame buffer formats, the format requested
-first takes precedence. The attempt to capture
-(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) or overlay
-(:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`) may fail with an ``EBUSY`` error
-code or return accordingly modified parameters..
-
-
-Overlay Window
-==============
-
-The overlaid image is determined by cropping and overlay window
-parameters. The former select an area of the video picture to capture,
-the latter how images are overlaid and clipped. Cropping initialization
-at minimum requires to reset the parameters to defaults. An example is
-given in :ref:`crop`.
-
-The overlay window is described by a struct
-:c:type:`v4l2_window`. It defines the size of the image,
-its position over the graphics surface and the clipping to be applied.
-To get the current parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OVERLAY`` and call the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
-struct :c:type:`v4l2_window` substructure named ``win``. It is not
-possible to retrieve a previously programmed clipping list or bitmap.
-
-To program the overlay window applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VIDEO_OVERLAY``, initialize the ``win`` substructure and
-call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. The driver
-adjusts the parameters against hardware limits and returns the actual
-parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
-about driver capabilities without actually changing driver state. Unlike
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
-
-The scaling factor of the overlaid image is implied by the width and
-height given in struct :c:type:`v4l2_window` and the size
-of the cropping rectangle. For more information see :ref:`crop`.
-
-When simultaneous capturing and overlay is supported and the hardware
-prohibits different image and window sizes, the size requested first
-takes precedence. The attempt to capture or overlay as well
-(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) may fail with an ``EBUSY`` error
-code or return accordingly modified parameters.
-
-
-.. c:type:: v4l2_window
-
-struct v4l2_window
-------------------
-
-``struct v4l2_rect w``
-    Size and position of the window relative to the top, left corner of
-    the frame buffer defined with
-    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The window can extend the
-    frame buffer width and height, the ``x`` and ``y`` coordinates can
-    be negative, and it can lie completely outside the frame buffer. The
-    driver clips the window accordingly, or if that is not possible,
-    modifies its size and/or position.
-
-``enum v4l2_field field``
-    Applications set this field to determine which video field shall be
-    overlaid, typically one of ``V4L2_FIELD_ANY`` (0),
-    ``V4L2_FIELD_TOP``, ``V4L2_FIELD_BOTTOM`` or
-    ``V4L2_FIELD_INTERLACED``. Drivers may have to choose a different
-    field order and return the actual setting here.
-
-``__u32 chromakey``
-    When chroma-keying has been negotiated with
-    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` applications set this field
-    to the desired pixel value for the chroma key. The format is the
-    same as the pixel format of the framebuffer (struct
-    :c:type:`v4l2_framebuffer` ``fmt.pixelformat``
-    field), with bytes in host order. E. g. for
-    :ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR32>` the value should
-    be 0xRRGGBB on a little endian, 0xBBGGRR on a big endian host.
-
-``struct v4l2_clip * clips``
-    When chroma-keying has *not* been negotiated and
-    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
-    applications can set this field to point to an array of clipping
-    rectangles.
-
-    Like the window coordinates w, clipping rectangles are defined
-    relative to the top, left corner of the frame buffer. However
-    clipping rectangles must not extend the frame buffer width and
-    height, and they must not overlap. If possible applications
-    should merge adjacent rectangles. Whether this must create
-    x-y or y-x bands, or the order of rectangles, is not defined. When
-    clip lists are not supported the driver ignores this field. Its
-    contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-    are undefined.
-
-``__u32 clipcount``
-    When the application set the ``clips`` field, this field must
-    contain the number of clipping rectangles in the list. When clip
-    lists are not supported the driver ignores this field, its contents
-    after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are undefined. When clip lists are
-    supported but no clipping is desired this field must be set to zero.
-
-``void * bitmap``
-    When chroma-keying has *not* been negotiated and
-    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
-    applications can set this field to point to a clipping bit mask.
-
-It must be of the same size as the window, ``w.width`` and ``w.height``.
-Each bit corresponds to a pixel in the overlaid image, which is
-displayed only when the bit is *set*. Pixel coordinates translate to
-bits like:
-
-
-.. code-block:: c
-
-    ((__u8 *) bitmap)[w.width * y + x / 8] & (1 << (x & 7))
-
-where ``0`` ≤ x < ``w.width`` and ``0`` ≤ y <``w.height``. [#f2]_
-
-When a clipping bit mask is not supported the driver ignores this field,
-its contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are
-undefined. When a bit mask is supported but no clipping is desired this
-field must be set to ``NULL``.
-
-Applications need not create a clip list or bit mask. When they pass
-both, or despite negotiating chroma-keying, the results are undefined.
-Regardless of the chosen method, the clipping abilities of the hardware
-may be limited in quantity or quality. The results when these limits are
-exceeded are undefined. [#f3]_
-
-``__u8 global_alpha``
-    The global alpha value used to blend the framebuffer with video
-    images, if global alpha blending has been negotiated
-    (``V4L2_FBUF_FLAG_GLOBAL_ALPHA``, see
-    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`,
-    :ref:`framebuffer-flags`).
-
-.. note::
-
-   This field was added in Linux 2.6.23, extending the
-   structure. However the :ref:`VIDIOC_[G|S|TRY]_FMT <VIDIOC_G_FMT>`
-   ioctls, which take a pointer to a :c:type:`v4l2_format`

-``struct v4l2_clip * next``
-    Pointer to the next clipping rectangle, ``NULL`` when this is the last

-    Vertical offset of the top, left corner of the rectangle, in pixels.
-    Offsets increase to the right and down.
-
-``__u32 width``
-    Width of the rectangle, in pixels.
-
-``__u32 height``
-    Height of the rectangle, in pixels.
-
-
-Enabling Overlay
-================
-
-To start or stop the frame buffer overlay applications call the
-:ref:`VIDIOC_OVERLAY` ioctl.
-
-.. [#f1]
-   A common application of two file descriptors is the XFree86
-   :ref:`Xv/V4L <xvideo>` interface driver and a V4L2 application.
-   While the X server controls video overlay, the application can take
-   advantage of memory mapping and DMA.
-
-   In the opinion of the designers of this API, no driver writer taking
-   the efforts to support simultaneous capturing and overlay will
-   restrict this ability by requiring a single file descriptor, as in
-   V4L and earlier versions of V4L2. Making this optional means
-   applications depending on two file descriptors need backup routines
-   to be compatible with all drivers, which is considerable more work
-   than using two fds in applications which do not. Also two fd's fit
-   the general concept of one file descriptor for each logical stream.
-   Hence as a complexity trade-off drivers *must* support two file
-   descriptors and *may* support single fd operation.
-
-.. [#f2]
-   Should we require ``w.width`` to be a multiple of eight?
-
-.. [#f3]
-   When the image is written into frame buffer memory it will be
-   undesirable if the driver clips out less pixels than expected,
-   because the application and graphics system are not aware these
-   regions need to be refreshed. The driver should clip out more pixels
-   or not write the image at all.
-
-.. [#f4]
-   The X Window system defines "regions" which are vectors of ``struct
-   BoxRec { short x1, y1, x2, y2; }`` with ``width = x2 - x1`` and
-   ``height = y2 - y1``, so one cannot pass X11 clip lists directly.

-Radio Interface
-***************
-
-This interface is intended for AM and FM (analog) radio receivers and

-
-Conventionally V4L2 radio devices are accessed through character device
-special files named ``/dev/radio`` and ``/dev/radio0`` to
-``/dev/radio63`` with major number 81 and minor numbers 64 to 127.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the radio interface set the ``V4L2_CAP_RADIO`` and

-:ref:`VIDIOC_QUERYCAP` ioctl. Other combinations of
-capability flags are reserved for future extensions.
-
-
-Supplemental Functions
-======================
-
-Radio devices can support :ref:`controls <control>`, and must support
-the :ref:`tuner or modulator <tuner>` ioctls.
-
-They do not support the video input or output, audio input or output,
-video standard, cropping and scaling, compression and streaming

-
-
-Programming
-===========
-
-Radio devices may have a couple audio controls (as discussed in
-:ref:`control`) such as a volume control, possibly custom controls.
-Further all radio devices have one tuner or modulator (these are
-discussed in :ref:`tuner`) with index number zero to select the radio
-frequency and to determine if a monaural or FM stereo program is
-received/emitted. Drivers switch automatically between AM and FM
-depending on the selected frequency. The

-**********************
-Raw VBI Data Interface
-**********************
-
-VBI is an abbreviation of Vertical Blanking Interval, a gap in the
-sequence of lines of an analog video signal. During VBI no picture
-information is transmitted, allowing some time while the electron beam
-of a cathode ray tube TV returns to the top of the screen. Using an
-oscilloscope you will find here the vertical synchronization pulses and
-short data packages ASK modulated [#f1]_ onto the video signal. These are
-transmissions of services such as Teletext or Closed Caption.
-
-Subject of this interface type is raw VBI data, as sampled off a video
-signal, or to be added to a signal for output. The data format is
-similar to uncompressed video images, a number of lines times a number
-of samples per line, we call this a VBI image.
-
-Conventionally V4L2 VBI devices are accessed through character device
-special files named ``/dev/vbi`` and ``/dev/vbi0`` to ``/dev/vbi31``
-with major number 81 and minor numbers 224 to 255. ``/dev/vbi`` is
-typically a symbolic link to the preferred VBI device. This convention
-applies to both input and output devices.
-
-To address the problems of finding related video and VBI devices VBI
-capturing and output is also available as device function under
-``/dev/video``. To capture or output raw VBI data with these devices
-applications must call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-Accessed as ``/dev/vbi``, raw VBI capturing or output is the default
-device function.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the raw VBI capturing or output API set the
-``V4L2_CAP_VBI_CAPTURE`` or ``V4L2_CAP_VBI_OUTPUT`` flags, respectively,
-in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
-read/write, streaming or asynchronous I/O methods must be supported. VBI
-devices may or may not have a tuner or modulator.
-
-
-Supplemental Functions
-======================
-
-VBI devices shall support :ref:`video input or output <video>`,
-:ref:`tuner or modulator <tuner>`, and :ref:`controls <control>`
-ioctls as needed. The :ref:`video standard <standard>` ioctls provide
-information vital to program a VBI device, therefore must be supported.
-
-
-Raw VBI Format Negotiation
-==========================
-
-Raw VBI sampling abilities can vary, in particular the sampling
-frequency. To properly interpret the data V4L2 specifies an ioctl to
-query the sampling parameters. Moreover, to allow for some flexibility
-applications can also suggest different parameters.
-
-As usual these parameters are *not* reset at :ref:`open() <func-open>`
-time to permit Unix tool chains, programming a device and then reading
-from it as if it was a plain file. Well written V4L2 applications should
-always ensure they really get what they want, requesting reasonable
-parameters and then checking if the actual parameters are suitable.
-
-To query the current raw VBI capture parameters applications set the
-``type`` field of a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_VBI_CAPTURE`` or ``V4L2_BUF_TYPE_VBI_OUTPUT``, and call
-the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
-structure. Drivers fill the struct
-:c:type:`v4l2_vbi_format` ``vbi`` member of the
-``fmt`` union.
-
-To request different parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` as above and initialize all
-fields of the struct :c:type:`v4l2_vbi_format`
-``vbi`` member of the ``fmt`` union, or better just modify the results
-of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl with a pointer to this structure. Drivers return an ``EINVAL`` error
-code only when the given parameters are ambiguous, otherwise they modify
-the parameters according to the hardware capabilities and return the
-actual parameters. When the driver allocates resources at this point, it
-may return an ``EBUSY`` error code to indicate the returned parameters are
-valid but the required resources are currently not available. That may
-happen for instance when the video and VBI areas to capture would
-overlap, or when the driver supports multiple opens and another process
-already requested VBI capturing or output. Anyway, applications must
-expect other resource allocation points which may return ``EBUSY``, at the
-:ref:`VIDIOC_STREAMON` ioctl and the first :ref:`read() <func-read>`
-, :ref:`write() <func-write>` and :ref:`select() <func-select>` calls.
-
-VBI devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all requests
-and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.

-
-	Drivers should be as flexibility as possible. For example, it may
-	be possible to extend or move the VBI capture window down to the
-	picture area, implementing a 'full field mode' to capture data
-	service transmissions embedded in the picture.
-
-	An application can set the first or second ``count`` value to zero
-	if no data is required from the respective field; ``count``\ [1]
-	if the scanning system is progressive, i. e. not interlaced. The
-	corresponding start value shall be ignored by the application and
-	driver. Anyway, drivers may not support single field capturing and
-	return both count values non-zero.
-
-	Both ``count`` values set to zero, or line numbers are outside the
-	bounds depicted\ [#f4]_, or a field image covering lines of two
-	fields, are invalid and shall not be returned by the driver.
-
-	To initialize the ``start`` and ``count`` fields, applications
-	must first determine the current video standard selection. The
-	:ref:`v4l2_std_id <v4l2-std-id>` or the ``framelines`` field

-    * - ``V4L2_VBI_UNSYNC``
-      - 0x0001
-      - This flag indicates hardware which does not properly distinguish

-	(lower scanning line numbers) first in memory. This may be a top
-	or bottom field depending on the video standard. When this flag is

-	fields are still in correct temporal order with the older field
-	first in memory. [#f3]_
-    * - ``V4L2_VBI_INTERLACED``
-      - 0x0002
-      - By default the two field images will be passed sequentially; all
-	lines of the first field followed by all lines of the second field
-	(compare :ref:`field-order` ``V4L2_FIELD_SEQ_TB`` and
-	``V4L2_FIELD_SEQ_BT``, whether the top or bottom field is first in

-	two fields are interlaced (cf. ``V4L2_FIELD_INTERLACED``). The
-	first line of the first field followed by the first line of the
-	second field, then the two second lines, and so on. Such a layout
-	may be necessary when the hardware has been programmed to capture
-	or output interlaced video images and is unable to separate the
-	fields for VBI capturing at the same time. For simplicity setting
-	this flag implies that both ``count`` values are equal and

-Remember the VBI image format depends on the selected video standard,

-current standard first. Attempts to read or write data ahead of format
-negotiation, or after switching the video standard which may invalidate
-the negotiated VBI parameters, should be refused by the driver. A format
-change during active I/O is not permitted.
-
-
-Reading and writing VBI images
-==============================
-
-To assure synchronization with the field number and easier
-implementation, the smallest unit of data passed at a time is one frame,
-consisting of two fields of VBI images immediately following in memory.
-
-The total size of a frame computes as follows:
-
-
-.. code-block:: c
-
-    (count[0] + count[1]) * samples_per_line * sample size in bytes
-
-The sample size is most likely always one byte, applications must check
-the ``sample_format`` field though, to function properly with other
-drivers.
-
-A VBI device may support :ref:`read/write <rw>` and/or streaming
-(:ref:`memory mapping <mmap>` or :ref:`user pointer <userp>`) I/O.
-The latter bears the possibility of synchronizing video and VBI data by
-using buffer timestamps.
-
-Remember the :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` ioctl and the
-first :ref:`read() <func-read>`, :ref:`write() <func-write>` and
-:ref:`select() <func-select>` call can be resource allocation
-points returning an ``EBUSY`` error code if the required hardware resources
-are temporarily unavailable, for example the device is already in use by
-another process.
-
-.. [#f1]
-   ASK: Amplitude-Shift Keying. A high signal level represents a '1'
-   bit, a low level a '0' bit.
-
-.. [#f2]
-   A few devices may be unable to sample VBI data at all but can extend
-   the video capture window to the VBI region.
-
-.. [#f3]
-   Most VBI services transmit on both fields, but some have different
-   semantics depending on the field number. These cannot be reliable
-   decoded or encoded when ``V4L2_VBI_UNSYNC`` is set.

-RDS Interface
-*************
-
-The Radio Data System transmits supplementary information in binary
-format, for example the station name or travel information, on an
-inaudible audio subcarrier of a radio program. This interface is aimed
-at devices capable of receiving and/or transmitting RDS information.
-
-For more information see the core RDS standard :ref:`iec62106` and the
-RBDS standard :ref:`nrsc4`.
-
-.. note::
-
-   Note that the RBDS standard as is used in the USA is almost
-   identical to the RDS standard. Any RDS decoder/encoder can also handle
-   RBDS. Only some of the fields have slightly different meanings. See the
-   RBDS standard for more information.
-
-The RBDS standard also specifies support for MMBS (Modified Mobile
-Search). This is a proprietary format which seems to be discontinued.
-The RDS interface does not support this format. Should support for MMBS
-(or the so-called 'E blocks' in general) be needed, then please contact
-the linux-media mailing list:
-`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the RDS capturing API set the
-``V4L2_CAP_RDS_CAPTURE`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. Any tuner that
-supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
-``capability`` field of struct :c:type:`v4l2_tuner`. If the
-driver only passes RDS blocks without interpreting the data the
-``V4L2_TUNER_CAP_RDS_BLOCK_IO`` flag has to be set, see
-:ref:`Reading RDS data <reading-rds-data>`. For future use the flag
-``V4L2_TUNER_CAP_RDS_CONTROLS`` has also been defined. However, a driver
-for a radio tuner with this capability does not yet exist, so if you are
-planning to write such a driver you should discuss this on the
-linux-media mailing list:
-`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
-
-Whether an RDS signal is present can be detected by looking at the
-``rxsubchans`` field of struct :c:type:`v4l2_tuner`: the
-``V4L2_TUNER_SUB_RDS`` will be set if RDS data was detected.
-
-Devices supporting the RDS output API set the ``V4L2_CAP_RDS_OUTPUT``
-flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. Any modulator that
-supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
-``capability`` field of struct
-:c:type:`v4l2_modulator`. In order to enable the RDS
-transmission one must set the ``V4L2_TUNER_SUB_RDS`` bit in the
-``txsubchans`` field of struct
-:c:type:`v4l2_modulator`. If the driver only passes RDS
-blocks without interpreting the data the ``V4L2_TUNER_CAP_RDS_BLOCK_IO``
-flag has to be set. If the tuner is capable of handling RDS entities
-like program identification codes and radio text, the flag
-``V4L2_TUNER_CAP_RDS_CONTROLS`` should be set, see

-Software Defined Radio Interface (SDR)
-**************************************
-
-SDR is an abbreviation of Software Defined Radio, the radio device which
-uses application software for modulation or demodulation. This interface
-is intended for controlling and data streaming of such devices.
-
-SDR devices are accessed through character device special files named
-``/dev/swradio0`` to ``/dev/swradio255`` with major number 81 and
-dynamically allocated minor numbers 0 to 255.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the SDR receiver interface set the
-``V4L2_CAP_SDR_CAPTURE`` and ``V4L2_CAP_TUNER`` flag in the
-``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
-device has an Analog to Digital Converter (ADC), which is a mandatory
-element for the SDR receiver.
-
-Devices supporting the SDR transmitter interface set the
-``V4L2_CAP_SDR_OUTPUT`` and ``V4L2_CAP_MODULATOR`` flag in the
-``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
-device has an Digital to Analog Converter (DAC), which is a mandatory
-element for the SDR transmitter.
-
-At least one of the read/write, streaming or asynchronous I/O methods
-must be supported.
-
-
-Supplemental Functions
-======================
-
-SDR devices can support :ref:`controls <control>`, and must support
-the :ref:`tuner` ioctls. Tuner ioctls are used for setting the
-ADC/DAC sampling rate (sampling frequency) and the possible radio
-frequency (RF).
-
-The ``V4L2_TUNER_SDR`` tuner type is used for setting SDR device ADC/DAC
-frequency, and the ``V4L2_TUNER_RF`` tuner type is used for setting
-radio frequency. The tuner index of the RF tuner (if any) must always
-follow the SDR tuner index. Normally the SDR tuner is #0 and the RF
-tuner is #1.
-
-The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl is
-not supported.
-
-
-Data Format Negotiation
-=======================
-
-The SDR device uses the :ref:`format` ioctls to select the
-capture and output format. Both the sampling resolution and the data
-streaming format are bound to that selectable format. In addition to the
-basic :ref:`format` ioctls, the
-:ref:`VIDIOC_ENUM_FMT` ioctl must be supported as
-well.
-
-To use the :ref:`format` ioctls applications set the ``type``
-field of a struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_SDR_CAPTURE`` or ``V4L2_BUF_TYPE_SDR_OUTPUT`` and use
-the struct :c:type:`v4l2_sdr_format` ``sdr`` member
-of the ``fmt`` union as needed per the desired operation. Currently
-there is two fields, ``pixelformat`` and ``buffersize``, of struct
-struct :c:type:`v4l2_sdr_format` which are used.
-Content of the ``pixelformat`` is V4L2 FourCC code of the data format.
-The ``buffersize`` field is maximum buffer size in bytes required for
-data transfer, set by the driver in order to inform application.

-*************************
-Sliced VBI Data Interface
-*************************
-
-VBI stands for Vertical Blanking Interval, a gap in the sequence of
-lines of an analog video signal. During VBI no picture information is
-transmitted, allowing some time while the electron beam of a cathode ray
-tube TV returns to the top of the screen.
-
-Sliced VBI devices use hardware to demodulate data transmitted in the
-VBI. V4L2 drivers shall *not* do this by software, see also the
-:ref:`raw VBI interface <raw-vbi>`. The data is passed as short
-packets of fixed size, covering one scan line each. The number of
-packets per video frame is variable.
-
-Sliced VBI capture and output devices are accessed through the same
-character special files as raw VBI devices. When a driver supports both
-interfaces, the default function of a ``/dev/vbi`` device is *raw* VBI
-capturing or output, and the sliced VBI function is only available after
-calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl as defined
-below. Likewise a ``/dev/video`` device may support the sliced VBI API,
-however the default function here is video capturing or output.
-Different file descriptors must be used to pass raw and sliced VBI data
-simultaneously, if this is supported by the driver.
-
-
-Querying Capabilities
-=====================
-
-Devices supporting the sliced VBI capturing or output API set the
-``V4L2_CAP_SLICED_VBI_CAPTURE`` or ``V4L2_CAP_SLICED_VBI_OUTPUT`` flag
-respectively, in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
-read/write, streaming or asynchronous :ref:`I/O methods <io>` must be
-supported. Sliced VBI devices may have a tuner or modulator.
-
-
-Supplemental Functions
-======================
-
-Sliced VBI devices shall support :ref:`video input or output <video>`
-and :ref:`tuner or modulator <tuner>` ioctls if they have these
-capabilities, and they may support :ref:`control` ioctls.
-The :ref:`video standard <standard>` ioctls provide information vital
-to program a sliced VBI device, therefore must be supported.
-
-
-.. _sliced-vbi-format-negotitation:
-
-Sliced VBI Format Negotiation
-=============================
-
-To find out which data services are supported by the hardware
-applications can call the
-:ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl.
-All drivers implementing the sliced VBI interface must support this
-ioctl. The results may differ from those of the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl when the number of VBI
-lines the hardware can capture or output per frame, or the number of
-services it can identify on a given line are limited. For example on PAL
-line 16 the hardware may be able to look for a VPS or Teletext signal,
-but not both at the same time.
-
-To determine the currently selected services applications set the
-``type`` field of struct :c:type:`v4l2_format` to
-``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` or
-``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``, and the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl fills the ``fmt.sliced``
-member, a struct
-:c:type:`v4l2_sliced_vbi_format`.
-
-Applications can request different parameters by initializing or
-modifying the ``fmt.sliced`` member and calling the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with a pointer to the
-struct :c:type:`v4l2_format` structure.
-
-The sliced VBI API is more complicated than the raw VBI API because the
-hardware must be told which VBI service to expect on each scan line. Not
-all services may be supported by the hardware on all lines (this is
-especially true for VBI output where Teletext is often unsupported and
-other services can only be inserted in one specific line). In many
-cases, however, it is sufficient to just set the ``service_set`` field
-to the required services and let the driver fill the ``service_lines``
-array according to hardware capabilities. Only if more precise control
-is needed should the programmer set the ``service_lines`` array
-explicitly.
-
-The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl modifies the parameters
-according to hardware capabilities. When the driver allocates resources
-at this point, it may return an ``EBUSY`` error code if the required
-resources are temporarily unavailable. Other resource allocation points
-which may return ``EBUSY`` can be the
-:ref:`VIDIOC_STREAMON` ioctl and the first
-:ref:`read() <func-read>`, :ref:`write() <func-write>` and
-:ref:`select() <func-select>` call.

-Drivers may return an ``EINVAL`` error code when applications attempt to
-read or write data without prior format negotiation, after switching the

-of struct :c:type:`v4l2_sliced_vbi_data` structures with one or
-more elements and a total size not exceeding ``io_size`` bytes. Likewise
-in streaming I/O mode one buffer of ``io_size`` bytes must contain data
-of one video frame. The ``id`` of unused
-struct :c:type:`v4l2_sliced_vbi_data` elements must be zero.

-been negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` or

-unknown the driver must pass the packets in transmitted order. The
-driver can insert empty packets with ``id`` set to zero anywhere in the
-packet array.
-
-To assure synchronization and to distinguish from frame dropping, when a
-captured frame does not carry any of the requested data services drivers
-must pass one or more empty packets. When an application fails to pass
-VBI data in time for output, the driver must output the last VPS and WSS
-packet again, and disable the output of Closed Caption and Teletext
-data, or output data which is ignored by Closed Caption and Teletext
-decoders.
-
-A sliced VBI device may support :ref:`read/write <rw>` and/or
-streaming (:ref:`memory mapping <mmap>` and/or
-:ref:`user pointer <userp>`) I/O. The latter bears the possibility of

-
-
-Sliced VBI Data in MPEG Streams
-===============================
-
-If a device can produce an MPEG output stream, it may be capable of
-providing
-:ref:`negotiated sliced VBI services <sliced-vbi-format-negotitation>`
-as data embedded in the MPEG stream. Users or applications control this
-sliced VBI data insertion with the
-:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
-control.
-
-If the driver does not provide the
-:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
-control, or only allows that control to be set to
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`,
-then the device cannot embed sliced VBI data in the MPEG stream.
-
-The
-:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
-control does not implicitly set the device driver to capture nor cease
-capturing sliced VBI data. The control only indicates to embed sliced
-VBI data in the MPEG stream, if an application has negotiated sliced VBI
-service be captured.
-
-It may also be the case that a device can embed sliced VBI data in only
-certain types of MPEG streams: for example in an MPEG-2 PS but not an
-MPEG-2 TS. In this situation, if sliced VBI data insertion is requested,
-the sliced VBI data will be embedded in MPEG stream types when
-supported, and silently omitted from MPEG stream types where sliced VBI
-data insertion is not supported by the device.
-
-The following subsections specify the format of the embedded sliced VBI
-data.
-
-
-MPEG Stream Embedded, Sliced VBI Data Format: NONE
---------------------------------------------------
-
-The
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`
-embedded sliced VBI format shall be interpreted by drivers as a control
-to cease embedding sliced VBI data in MPEG streams. Neither the device
-nor driver shall insert "empty" embedded sliced VBI data packets in the
-MPEG stream when this format is set. No MPEG stream data structures are
-specified for this format.
-
-
-MPEG Stream Embedded, Sliced VBI Data Format: IVTV
---------------------------------------------------
-
-The
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
-embedded sliced VBI format, when supported, indicates to the driver to
-embed up to 36 lines of sliced VBI data per frame in an MPEG-2 *Private
-Stream 1 PES* packet encapsulated in an MPEG-2 *Program Pack* in the
-MPEG stream.
-
-*Historical context*: This format specification originates from a
-custom, embedded, sliced VBI data format used by the ``ivtv`` driver.
-This format has already been informally specified in the kernel sources
-in the file ``Documentation/media/v4l-drivers/cx2341x.rst`` . The
-maximum size of the payload and other aspects of this format are driven
-by the CX23415 MPEG decoder's capabilities and limitations with respect
-to extracting, decoding, and displaying sliced VBI data embedded within
-an MPEG stream.
-
-This format's use is *not* exclusive to the ``ivtv`` driver *nor*
-exclusive to CX2341x devices, as the sliced VBI data packet insertion
-into the MPEG stream is implemented in driver software. At least the
-``cx18`` driver provides sliced VBI data insertion into an MPEG-2 PS in
-this format as well.
-
-The following definitions specify the payload of the MPEG-2 *Private
-Stream 1 PES* packets that contain sliced VBI data when
-:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
-is set. (The MPEG-2 *Private Stream 1 PES* packet header and
-encapsulating MPEG-2 *Program Pack* header are not detailed here. Please
-refer to the MPEG-2 specifications for details on those packet headers.)
-
-The payload of the MPEG-2 *Private Stream 1 PES* packets that contain
-sliced VBI data is specified by struct
-:c:type:`v4l2_mpeg_vbi_fmt_ivtv`. The
-payload is variable length, depending on the actual number of lines of
-sliced VBI data present in a video frame. The payload may be padded at
-the end with unspecified fill bytes to align the end of the payload to a
-4-byte boundary. The payload shall never exceed 1552 bytes (2 fields
-with 18 lines/field with 43 bytes of data/line and a 4 byte magic
-number).

-********************
-Sub-device Interface
-********************
-
-The complex nature of V4L2 devices, where hardware is often made of
-several integrated circuits that need to interact with each other in a
-controlled way, leads to complex V4L2 drivers. The drivers usually
-reflect the hardware model in software, and model the different hardware
-components as software blocks called sub-devices.
-
-V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
-implements the media device API, they will automatically inherit from
-media entities. Applications will be able to enumerate the sub-devices
-and discover the hardware topology using the media entities, pads and
-links enumeration API.
-
-In addition to make sub-devices discoverable, drivers can also choose to
-make them directly configurable by applications. When both the
-sub-device driver and the V4L2 device driver support this, sub-devices
-will feature a character device node on which ioctls can be called to
-
--  query, read and write sub-devices controls
-
--  subscribe and unsubscribe to events and retrieve them
-
--  negotiate image formats on individual pads
-
-Sub-device character device nodes, conventionally named
-``/dev/v4l-subdev*``, use major number 81.
-
-
-Controls
-========
-
-Most V4L2 controls are implemented by sub-device hardware. Drivers
-usually merge all controls and expose them through video device nodes.
-Applications can control all sub-devices through a single interface.
-
-Complex devices sometimes implement the same control in different pieces
-of hardware. This situation is common in embedded platforms, where both
-sensors and image processing hardware implement identical functions,
-such as contrast adjustment, white balance or faulty pixels correction.
-As the V4L2 controls API doesn't support several identical controls in a
-single device, all but one of the identical controls are hidden.
-
-Applications can access those hidden controls through the sub-device
-node with the V4L2 control API described in :ref:`control`. The ioctls
-behave identically as when issued on V4L2 device nodes, with the
-exception that they deal only with controls implemented in the
-sub-device.
-
-Depending on the driver, those controls might also be exposed through
-one (or several) V4L2 device nodes.
-
-
-Events
-======
-
-V4L2 sub-devices can notify applications of events as described in
-:ref:`event`. The API behaves identically as when used on V4L2 device
-nodes, with the exception that it only deals with events generated by
-the sub-device. Depending on the driver, those events might also be
-reported on one (or several) V4L2 device nodes.

-
-Pad-level Formats
-=================
-
-.. warning::
-
-    Pad-level formats are only applicable to very complex devices that
-    need to expose low-level format configuration to user space. Generic
-    V4L2 applications do *not* need to use the API described in this
-    section.
-
-.. note::
-
-    For the purpose of this section, the term *format* means the
-    combination of media bus data format, frame width and frame height.
-
-Image formats are typically negotiated on video capture and output
-devices using the format and
-:ref:`selection <VIDIOC_SUBDEV_G_SELECTION>` ioctls. The driver is
-responsible for configuring every block in the video pipeline according
-to the requested format at the pipeline input and/or output.
-
-For complex devices, such as often found in embedded systems, identical
-image sizes at the output of a pipeline can be achieved using different
-hardware configurations. One such example is shown on
-:ref:`pipeline-scaling`, where image scaling can be performed on both
-the video sensor and the host image processing hardware.
-
-
-.. _pipeline-scaling:
-
-.. kernel-figure:: pipeline.dot
-    :alt:   pipeline.dot
-    :align: center
-
-    Image Format Negotiation on Pipelines
-
-    High quality and high speed pipeline configuration
-
-
-
-The sensor scaler is usually of less quality than the host scaler, but
-scaling on the sensor is required to achieve higher frame rates.
-Depending on the use case (quality vs. speed), the pipeline must be
-configured differently. Applications need to configure the formats at
-every point in the pipeline explicitly.
-
-Drivers that implement the :ref:`media API <media-controller-intro>`
-can expose pad-level image format configuration to applications. When
-they do, applications can use the
-:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls. to
-negotiate formats on a per-pad basis.
-
-Applications are responsible for configuring coherent parameters on the
-whole pipeline and making sure that connected pads have compatible
-formats. The pipeline is checked for formats mismatch at
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` time, and an ``EPIPE`` error
-code is then returned if the configuration is invalid.
-
-Pad-level image format configuration support can be tested by calling
-the :ref:`VIDIOC_SUBDEV_G_FMT` ioctl on pad
-0. If the driver returns an ``EINVAL`` error code pad-level format
-configuration is not supported by the sub-device.
-
-
-Format Negotiation
-------------------
-
-Acceptable formats on pads can (and usually do) depend on a number of
-external parameters, such as formats on other pads, active links, or
-even controls. Finding a combination of formats on all pads in a video
-pipeline, acceptable to both application and driver, can't rely on
-formats enumeration only. A format negotiation mechanism is required.
-
-Central to the format negotiation mechanism are the get/set format
-operations. When called with the ``which`` argument set to
-:ref:`V4L2_SUBDEV_FORMAT_TRY <VIDIOC_SUBDEV_G_FMT>`, the
-:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls operate on
-a set of formats parameters that are not connected to the hardware
-configuration. Modifying those 'try' formats leaves the device state
-untouched (this applies to both the software state stored in the driver
-and the hardware state stored in the device itself).
-
-While not kept as part of the device state, try formats are stored in
-the sub-device file handles. A
-:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` call will return
-the last try format set *on the same sub-device file handle*. Several
-applications querying the same sub-device at the same time will thus not
-interact with each other.
-
-To find out whether a particular format is supported by the device,
-applications use the
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl. Drivers
-verify and, if needed, change the requested ``format`` based on device
-requirements and return the possibly modified value. Applications can
-then choose to try a different format or accept the returned value and
-continue.
-
-Formats returned by the driver during a negotiation iteration are
-guaranteed to be supported by the device. In particular, drivers
-guarantee that a returned format will not be further changed if passed
-to an :ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` call as-is
-(as long as external parameters, such as formats on other pads or links'
-configuration are not changed).
-
-Drivers automatically propagate formats inside sub-devices. When a try
-or active format is set on a pad, corresponding formats on other pads of
-the same sub-device can be modified by the driver. Drivers are free to
-modify formats as required by the device. However, they should comply
-with the following rules when possible:
-
--  Formats should be propagated from sink pads to source pads. Modifying
-   a format on a source pad should not modify the format on any sink
-   pad.
-
--  Sub-devices that scale frames using variable scaling factors should
-   reset the scale factors to default values when sink pads formats are
-   modified. If the 1:1 scaling ratio is supported, this means that
-   source pads formats should be reset to the sink pads formats.
-
-Formats are not propagated across links, as that would involve
-propagating them from one sub-device file handle to another.
-Applications must then take care to configure both ends of every link
-explicitly with compatible formats. Identical formats on the two ends of
-a link are guaranteed to be compatible. Drivers are free to accept
-different formats matching device requirements as being compatible.

-1. Initial state. The sensor source pad format is set to its native 3MP

-   host frontend and scaler sink and source pads have the default
-   values, as well as the compose rectangle on the scaler's sink pad.
-
-2. The application configures the frontend sink pad format's size to

-   driver propagates the format to the frontend source pad.
-
-3. The application configures the scaler sink pad format's size to

-   match the frontend source size and media bus code. The media bus code
-   on the sink pad is set to V4L2_MBUS_FMT_SGRBG_1X8. The driver

-formats by drivers. To avoid modifying the hardware state during format
-negotiation, applications should negotiate try formats first and then
-modify the active settings using the try formats returned during the
-last negotiation iteration. This guarantees that the active format will
-be applied as-is by the driver without being modified.
-
-
-.. _v4l2-subdev-selections:
-
-Selections: cropping, scaling and composition
----------------------------------------------
-
-Many sub-devices support cropping frames on their input or output pads
-(or possible even on both). Cropping is used to select the area of
-interest in an image, typically on an image sensor or a video decoder.
-It can also be used as part of digital zoom implementations to select
-the area of the image that will be scaled up.
-
-Crop settings are defined by a crop rectangle and represented in a
-struct :c:type:`v4l2_rect` by the coordinates of the top
-left corner and the rectangle size. Both the coordinates and sizes are
-expressed in pixels.
-
-As for pad formats, drivers store try and active rectangles for the
-selection targets :ref:`v4l2-selections-common`.
-
-On sink pads, cropping is applied relative to the current pad format.
-The pad format represents the image size as received by the sub-device
-from the previous block in the pipeline, and the crop rectangle
-represents the sub-image that will be transmitted further inside the
-sub-device for processing.
-
-The scaling operation changes the size of the image by scaling it to new
-dimensions. The scaling ratio isn't specified explicitly, but is implied
-from the original and scaled image sizes. Both sizes are represented by
-struct :c:type:`v4l2_rect`.
-
-Scaling support is optional. When supported by a subdev, the crop
-rectangle on the subdev's sink pad is scaled to the size configured
-using the
-:ref:`VIDIOC_SUBDEV_S_SELECTION <VIDIOC_SUBDEV_G_SELECTION>` IOCTL
-using ``V4L2_SEL_TGT_COMPOSE`` selection target on the same pad. If the
-subdev supports scaling but not composing, the top and left values are
-not used and must always be set to zero.
-
-On source pads, cropping is similar to sink pads, with the exception
-that the source size from which the cropping is performed, is the
-COMPOSE rectangle on the sink pad. In both sink and source pads, the
-crop rectangle must be entirely contained inside the source image size
-for the crop operation.
-
-The drivers should always use the closest possible rectangle the user
-requests on all selection targets, unless specifically told otherwise.
-``V4L2_SEL_FLAG_GE`` and ``V4L2_SEL_FLAG_LE`` flags may be used to round
-the image size either up or down. :ref:`v4l2-selection-flags`
-
-
-Types of selection targets
---------------------------
-
-
-Actual targets
-^^^^^^^^^^^^^^
-
-Actual targets (without a postfix) reflect the actual hardware
-configuration at any point of time. There is a BOUNDS target
-corresponding to every actual target.
-
-
-BOUNDS targets
-^^^^^^^^^^^^^^
-
-BOUNDS targets is the smallest rectangle that contains all valid actual
-rectangles. It may not be possible to set the actual rectangle as large
-as the BOUNDS rectangle, however. This may be because e.g. a sensor's
-pixel array is not rectangular but cross-shaped or round. The maximum
-size may also be smaller than the BOUNDS rectangle.
-
-
-Order of configuration and format propagation
----------------------------------------------
-
-Inside subdevs, the order of image processing steps will always be from
-the sink pad towards the source pad. This is also reflected in the order
-in which the configuration must be performed by the user: the changes
-made will be propagated to any subsequent stages. If this behaviour is
-not desired, the user must set ``V4L2_SEL_FLAG_KEEP_CONFIG`` flag. This
-flag causes no propagation of the changes are allowed in any
-circumstances. This may also cause the accessed rectangle to be adjusted
-by the driver, depending on the properties of the underlying hardware.
-
-The coordinates to a step always refer to the actual size of the
-previous step. The exception to this rule is the sink compose
-rectangle, which refers to the sink compose bounds rectangle --- if it
-is supported by the hardware.
-
-1. Sink pad format. The user configures the sink pad format. This format
-   defines the parameters of the image the entity receives through the
-   pad for further processing.
-
-2. Sink pad actual crop selection. The sink pad crop defines the crop
-   performed to the sink pad format.
-
-3. Sink pad actual compose selection. The size of the sink pad compose
-   rectangle defines the scaling ratio compared to the size of the sink
-   pad crop rectangle. The location of the compose rectangle specifies
-   the location of the actual sink compose rectangle in the sink compose
-   bounds rectangle.
-
-4. Source pad actual crop selection. Crop on the source pad defines crop
-   performed to the image in the sink compose bounds rectangle.
-
-5. Source pad format. The source pad format defines the output pixel
-   format of the subdev, as well as the other parameters with the
-   exception of the image width and height. Width and height are defined
-   by the size of the source pad actual crop selection.
-
-Accessing any of the above rectangles not supported by the subdev will
-return ``EINVAL``. Any rectangle referring to a previous unsupported
-rectangle coordinates will instead refer to the previous supported
-rectangle. For example, if sink crop is not supported, the compose
-selection will refer to the sink pad format dimensions instead.

-
-    **Figure 4.5. Image processing in subdevs: simple crop example**
-
-In the above example, the subdev supports cropping on its sink pad. To
-configure it, the user sets the media bus format on the subdev's sink
-pad. Now the actual crop rectangle can be set on the sink pad --- the
-location and size of this rectangle reflect the location and size of a
-rectangle to be cropped from the sink format. The size of the sink crop
-rectangle will also be the size of the format of the subdev's source
-pad.

-
-    **Figure 4.6. Image processing in subdevs: scaling with multiple sources**
-
-In this example, the subdev is capable of first cropping, then scaling
-and finally cropping for two source pads individually from the resulting
-scaled image. The location of the scaled image in the cropped image is
-ignored in sink compose target. Both of the locations of the source crop
-rectangles refer to the sink scaling rectangle, independently cropping
-an area at location specified by the source crop rectangle from it.

-
-    **Figure 4.7. Image processing in subdevs: scaling and composition with multiple sinks and sources**
-
-The subdev driver supports two sink pads and two source pads. The images
-from both of the sink pads are individually cropped, then scaled and
-further composed on the composition bounds rectangle. From that, two
-independent streams are cropped and sent out of the subdev from the
-source pads.

-Touch Devices
-*************
-
-Touch devices are accessed through character device special files named
-``/dev/v4l-touch0`` to ``/dev/v4l-touch255`` with major number 81 and
-dynamically allocated minor numbers 0 to 255.
-
-Overview
-========
-
-Sensors may be Optical, or Projected Capacitive touch (PCT).
-
-Processing is required to analyse the raw data and produce input events. In
-some systems, this may be performed on the ASIC and the raw data is purely a
-side-channel for diagnostics or tuning. In other systems, the ASIC is a simple
-analogue front end device which delivers touch data at high rate, and any touch
-processing must be done on the host.
-
-For capacitive touch sensing, the touchscreen is composed of an array of
-horizontal and vertical conductors (alternatively called rows/columns, X/Y
-lines, or tx/rx). Mutual Capacitance measured is at the nodes where the
-conductors cross. Alternatively, Self Capacitance measures the signal from each
-column and row independently.
-
-A touch input may be determined by comparing the raw capacitance measurement to
-a no-touch reference (or "baseline") measurement:
-
-Delta = Raw - Reference
-
-The reference measurement takes account of variations in the capacitance across
-the touch sensor matrix, for example manufacturing irregularities,
-environmental or edge effects.
-
-Querying Capabilities
-=====================
-
-Devices supporting the touch interface set the ``V4L2_CAP_VIDEO_CAPTURE`` flag
-and the ``V4L2_CAP_TOUCH`` flag in the ``capabilities`` field of
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl.
-
-At least one of the read/write or streaming I/O methods must be
-supported.
-
-The formats supported by touch devices are documented in
-:ref:`Touch Formats <tch-formats>`.
-
-Data Format Negotiation
-=======================
-
-A touch device may support any I/O method.

-********************************
-Differences between V4L and V4L2
-********************************
-
-The Video For Linux API was first introduced in Linux 2.1 to unify and
-replace various TV and radio device related interfaces, developed
-independently by driver writers in prior years. Starting with Linux 2.5
-the much improved V4L2 API replaces the V4L API. The support for the old
-V4L calls were removed from Kernel, but the library :ref:`libv4l`
-supports the conversion of a V4L API system call into a V4L2 one.
-
-
-Opening and Closing Devices
-===========================
-
-For compatibility reasons the character device file names recommended
-for V4L2 video capture, overlay, radio and raw vbi capture devices did
-not change from those used by V4L. They are listed in :ref:`devices`
-and below in :ref:`v4l-dev`.
-
-The teletext devices (minor range 192-223) have been removed in V4L2 and
-no longer exist. There is no hardware available anymore for handling
-pure teletext. Instead raw or sliced VBI is used.
-
-The V4L ``videodev`` module automatically assigns minor numbers to
-drivers in load order, depending on the registered device type. We
-recommend that V4L2 drivers by default register devices with the same
-numbers, but the system administrator can assign arbitrary minor numbers
-using driver module options. The major device number remains 81.

-V4L2 drivers *may* support multiple opens, see :ref:`open` for details
-and consequences.
-
-V4L drivers respond to V4L2 ioctls with an ``EINVAL`` error code.
-
-
-Querying Capabilities
-=====================
-
-The V4L ``VIDIOCGCAP`` ioctl is equivalent to V4L2's
-:ref:`VIDIOC_QUERYCAP`.
-
-The ``name`` field in struct ``video_capability`` became
-``card`` in struct :c:type:`v4l2_capability`, ``type``
-was replaced by ``capabilities``. Note V4L2 does not distinguish between
-device types like this, better think of basic video input, video output
-and radio devices supporting a set of related functions like video
-capturing, video overlay and VBI capturing. See :ref:`open` for an
-introduction.

-
-The ``audios`` field was replaced by ``capabilities`` flag

-
-The ``maxwidth``, ``maxheight``, ``minwidth`` and ``minheight`` fields
-were removed. Calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl with the desired
-dimensions returns the closest size possible, taking into account the
-current video standard, cropping and scaling limitations.
-
-
-Video Sources
-=============
-
-V4L provides the ``VIDIOCGCHAN`` and ``VIDIOCSCHAN`` ioctl using struct
-``video_channel`` to enumerate the video inputs of a V4L
-device. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_ENUMINPUT`,
-:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
-:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` using struct
-:c:type:`v4l2_input` as discussed in :ref:`video`.
-
-The ``channel`` field counting inputs was renamed to ``index``, the
-video input types were renamed as follows:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct ``video_channel`` ``type``
-      - struct :c:type:`v4l2_input` ``type``
-    * - ``VIDEO_TYPE_TV``
-      - ``V4L2_INPUT_TYPE_TUNER``
-    * - ``VIDEO_TYPE_CAMERA``
-      - ``V4L2_INPUT_TYPE_CAMERA``
-
-
-Unlike the ``tuners`` field expressing the number of tuners of this
-input, V4L2 assumes each video input is connected to at most one tuner.
-However a tuner can have more than one input, i. e. RF connectors, and a
-device can have multiple tuners. The index number of the tuner
-associated with the input, if any, is stored in field ``tuner`` of
-struct :c:type:`v4l2_input`. Enumeration of tuners is
-discussed in :ref:`tuner`.
-
-The redundant ``VIDEO_VC_TUNER`` flag was dropped. Video inputs
-associated with a tuner are of type ``V4L2_INPUT_TYPE_TUNER``. The
-``VIDEO_VC_AUDIO`` flag was replaced by the ``audioset`` field. V4L2
-considers devices with up to 32 audio inputs. Each set bit in the
-``audioset`` field represents one audio input this video input combines
-with. For information about audio inputs and how to switch between them
-see :ref:`audio`.
-
-The ``norm`` field describing the supported video standards was replaced
-by ``std``. The V4L specification mentions a flag ``VIDEO_VC_NORM``
-indicating whether the standard can be changed. This flag was a later
-addition together with the ``norm`` field and has been removed in the
-meantime. V4L2 has a similar, albeit more comprehensive approach to
-video standards, see :ref:`standard` for more information.
-
-
-Tuning
-======
-
-The V4L ``VIDIOCGTUNER`` and ``VIDIOCSTUNER`` ioctl and struct
-``video_tuner`` can be used to enumerate the tuners of a
-V4L TV or radio device. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
-:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` using struct
-:c:type:`v4l2_tuner`. Tuners are covered in :ref:`tuner`.
-
-The ``tuner`` field counting tuners was renamed to ``index``. The fields
-``name``, ``rangelow`` and ``rangehigh`` remained unchanged.
-
-The ``VIDEO_TUNER_PAL``, ``VIDEO_TUNER_NTSC`` and ``VIDEO_TUNER_SECAM``
-flags indicating the supported video standards were dropped. This
-information is now contained in the associated struct
-:c:type:`v4l2_input`. No replacement exists for the
-``VIDEO_TUNER_NORM`` flag indicating whether the video standard can be
-switched. The ``mode`` field to select a different video standard was
-replaced by a whole new set of ioctls and structures described in
-:ref:`standard`. Due to its ubiquity it should be mentioned the BTTV
-driver supports several standards in addition to the regular
-``VIDEO_MODE_PAL`` (0), ``VIDEO_MODE_NTSC``, ``VIDEO_MODE_SECAM`` and
-``VIDEO_MODE_AUTO`` (3). Namely N/PAL Argentina, M/PAL, N/PAL, and NTSC
-Japan with numbers 3-6 (sic).
-
-The ``VIDEO_TUNER_STEREO_ON`` flag indicating stereo reception became
-``V4L2_TUNER_SUB_STEREO`` in field ``rxsubchans``. This field also
-permits the detection of monaural and bilingual audio, see the
-definition of struct :c:type:`v4l2_tuner` for details.
-Presently no replacement exists for the ``VIDEO_TUNER_RDS_ON`` and
-``VIDEO_TUNER_MBS_ON`` flags.
-
-The ``VIDEO_TUNER_LOW`` flag was renamed to ``V4L2_TUNER_CAP_LOW`` in
-the struct :c:type:`v4l2_tuner` ``capability`` field.
-
-The ``VIDIOCGFREQ`` and ``VIDIOCSFREQ`` ioctl to change the tuner
-frequency where renamed to
-:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`. They take a pointer
-to a struct :c:type:`v4l2_frequency` instead of an
-unsigned long integer.
-

-
-Image Properties
-================
-
-V4L2 has no equivalent of the ``VIDIOCGPICT`` and ``VIDIOCSPICT`` ioctl
-and struct ``video_picture``. The following fields where
-replaced by V4L2 controls accessible with the
-:ref:`VIDIOC_QUERYCTRL`,
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:

-    * - ``whiteness``
-      - ``V4L2_CID_WHITENESS``
-
-
-The V4L picture controls are assumed to range from 0 to 65535 with no
-particular reset value. The V4L2 API permits arbitrary limits and
-defaults which can be queried with the
-:ref:`VIDIOC_QUERYCTRL` ioctl. For general
-information about controls see :ref:`control`.
-
-The ``depth`` (average number of bits per pixel) of a video image is
-implied by the selected image format. V4L2 does not explicitly provide
-such information assuming applications recognizing the format are aware
-of the image depth and others need not know. The ``palette`` field moved
-into the struct :c:type:`v4l2_pix_format`:

-
-V4L2 image formats are defined in :ref:`pixfmt`. The image format can
-be selected with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-
-Audio
-=====
-
-The ``VIDIOCGAUDIO`` and ``VIDIOCSAUDIO`` ioctl and struct
-``video_audio`` are used to enumerate the audio inputs
-of a V4L device. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
-:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` using struct
-:c:type:`v4l2_audio` as discussed in :ref:`audio`.
-
-The ``audio`` "channel number" field counting audio inputs was renamed
-to ``index``.
-
-On ``VIDIOCSAUDIO`` the ``mode`` field selects *one* of the
-``VIDEO_SOUND_MONO``, ``VIDEO_SOUND_STEREO``, ``VIDEO_SOUND_LANG1`` or
-``VIDEO_SOUND_LANG2`` audio demodulation modes. When the current audio
-standard is BTSC ``VIDEO_SOUND_LANG2`` refers to SAP and
-``VIDEO_SOUND_LANG1`` is meaningless. Also undocumented in the V4L
-specification, there is no way to query the selected mode. On
-``VIDIOCGAUDIO`` the driver returns the *actually received* audio
-programmes in this field. In the V4L2 API this information is stored in
-the struct :c:type:`v4l2_tuner` ``rxsubchans`` and
-``audmode`` fields, respectively. See :ref:`tuner` for more
-information on tuners. Related to audio modes struct
-:c:type:`v4l2_audio` also reports if this is a mono or
-stereo input, regardless if the source is a tuner.
-
-The following fields where replaced by V4L2 controls accessible with the
-:ref:`VIDIOC_QUERYCTRL`,
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct ``video_audio``
-      - V4L2 Control ID
-    * - ``volume``
-      - ``V4L2_CID_AUDIO_VOLUME``
-    * - ``bass``
-      - ``V4L2_CID_AUDIO_BASS``
-    * - ``treble``
-      - ``V4L2_CID_AUDIO_TREBLE``
-    * - ``balance``
-      - ``V4L2_CID_AUDIO_BALANCE``
-
-
-To determine which of these controls are supported by a driver V4L
-provides the ``flags`` ``VIDEO_AUDIO_VOLUME``, ``VIDEO_AUDIO_BASS``,
-``VIDEO_AUDIO_TREBLE`` and ``VIDEO_AUDIO_BALANCE``. In the V4L2 API the
-:ref:`VIDIOC_QUERYCTRL` ioctl reports if the
-respective control is supported. Accordingly the ``VIDEO_AUDIO_MUTABLE``
-and ``VIDEO_AUDIO_MUTE`` flags where replaced by the boolean
-``V4L2_CID_AUDIO_MUTE`` control.
-
-All V4L2 controls have a ``step`` attribute replacing the struct
-``video_audio`` ``step`` field. The V4L audio controls
-are assumed to range from 0 to 65535 with no particular reset value. The
-V4L2 API permits arbitrary limits and defaults which can be queried with
-the :ref:`VIDIOC_QUERYCTRL` ioctl. For general
-information about controls see :ref:`control`.
-
-
-Frame Buffer Overlay
-====================
-
-The V4L2 ioctls equivalent to ``VIDIOCGFBUF`` and ``VIDIOCSFBUF`` are
-:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
-:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The ``base`` field of struct
-``video_buffer`` remained unchanged, except V4L2 defines
-a flag to indicate non-destructive overlays instead of a ``NULL``
-pointer. All other fields moved into the struct
-:c:type:`v4l2_pix_format` ``fmt`` substructure of
-struct :c:type:`v4l2_framebuffer`. The ``depth``
-field was replaced by ``pixelformat``. See :ref:`pixfmt-rgb` for a
-list of RGB formats and their respective color depths.
-
-Instead of the special ioctls ``VIDIOCGWIN`` and ``VIDIOCSWIN`` V4L2
-uses the general-purpose data format negotiation ioctls
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
-:c:type:`v4l2_format` as argument. Here the ``win`` member
-of the ``fmt`` union is used, a struct
-:c:type:`v4l2_window`.
-
-The ``x``, ``y``, ``width`` and ``height`` fields of struct
-``video_window`` moved into struct
-:c:type:`v4l2_rect` substructure ``w`` of struct
-:c:type:`v4l2_window`. The ``chromakey``, ``clips``, and
-``clipcount`` fields remained unchanged. Struct
-``video_clip`` was renamed to struct
-:c:type:`v4l2_clip`, also containing a struct
-:c:type:`v4l2_rect`, but the semantics are still the same.
-
-The ``VIDEO_WINDOW_INTERLACE`` flag was dropped. Instead applications
-must set the ``field`` field to ``V4L2_FIELD_ANY`` or
-``V4L2_FIELD_INTERLACED``. The ``VIDEO_WINDOW_CHROMAKEY`` flag moved
-into struct :c:type:`v4l2_framebuffer`, under the new
-name ``V4L2_FBUF_FLAG_CHROMAKEY``.
-
-In V4L, storing a bitmap pointer in ``clips`` and setting ``clipcount``
-to ``VIDEO_CLIP_BITMAP`` (-1) requests bitmap clipping, using a fixed
-size bitmap of 1024 × 625 bits. Struct :c:type:`v4l2_window`
-has a separate ``bitmap`` pointer field for this purpose and the bitmap
-size is determined by ``w.width`` and ``w.height``.
-
-The ``VIDIOCCAPTURE`` ioctl to enable or disable overlay was renamed to
-:ref:`VIDIOC_OVERLAY`.
-
-
-Cropping
-========
-
-To capture only a subsection of the full picture V4L defines the
-``VIDIOCGCAPTURE`` and ``VIDIOCSCAPTURE`` ioctls using struct
-``video_capture``. The equivalent V4L2 ioctls are
-:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` using struct
-:c:type:`v4l2_crop`, and the related
-:ref:`VIDIOC_CROPCAP` ioctl. This is a rather
-complex matter, see :ref:`crop` for details.
-
-The ``x``, ``y``, ``width`` and ``height`` fields moved into struct
-:c:type:`v4l2_rect` substructure ``c`` of struct
-:c:type:`v4l2_crop`. The ``decimation`` field was dropped. In
-the V4L2 API the scaling factor is implied by the size of the cropping
-rectangle and the size of the captured or overlaid image.
-
-The ``VIDEO_CAPTURE_ODD`` and ``VIDEO_CAPTURE_EVEN`` flags to capture
-only the odd or even field, respectively, were replaced by
-``V4L2_FIELD_TOP`` and ``V4L2_FIELD_BOTTOM`` in the field named
-``field`` of struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_window`. These structures are used to
-select a capture or overlay format with the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-
-Reading Images, Memory Mapping
-==============================
-
-
-Capturing using the read method
--------------------------------
-
-There is no essential difference between reading images from a V4L or
-V4L2 device using the :ref:`read() <func-read>` function, however V4L2
-drivers are not required to support this I/O method. Applications can
-determine if the function is available with the
-:ref:`VIDIOC_QUERYCAP` ioctl. All V4L2 devices
-exchanging data with applications must support the
-:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
-functions.
-
-To select an image format and size, V4L provides the ``VIDIOCSPICT`` and
-``VIDIOCSWIN`` ioctls. V4L2 uses the general-purpose data format
-negotiation ioctls :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
-:c:type:`v4l2_format` as argument, here the struct
-:c:type:`v4l2_pix_format` named ``pix`` of its
-``fmt`` union is used.
-
-For more information about the V4L2 read interface see :ref:`rw`.
-
-
-Capturing using memory mapping
-------------------------------
-
-Applications can read from V4L devices by mapping buffers in device
-memory, or more often just buffers allocated in DMA-able system memory,
-into their address space. This avoids the data copying overhead of the
-read method. V4L2 supports memory mapping as well, with a few
-differences.
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - V4L
-      - V4L2
-    * -
-      - The image format must be selected before buffers are allocated,
-	with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When no
-	format is selected the driver may use the last, possibly by
-	another application requested format.
-    * - Applications cannot change the number of buffers. The it is built
-	into the driver, unless it has a module option to change the
-	number when the driver module is loaded.
-      - The :ref:`VIDIOC_REQBUFS` ioctl allocates the
-	desired number of buffers, this is a required step in the
-	initialization sequence.
-    * - Drivers map all buffers as one contiguous range of memory. The
-	``VIDIOCGMBUF`` ioctl is available to query the number of buffers,
-	the offset of each buffer from the start of the virtual file, and
-	the overall amount of memory used, which can be used as arguments
-	for the :ref:`mmap() <func-mmap>` function.
-      - Buffers are individually mapped. The offset and size of each
-	buffer can be determined with the
-	:ref:`VIDIOC_QUERYBUF` ioctl.
-    * - The ``VIDIOCMCAPTURE`` ioctl prepares a buffer for capturing. It
-	also determines the image format for this buffer. The ioctl
-	returns immediately, eventually with an ``EAGAIN`` error code if no
-	video signal had been detected. When the driver supports more than
-	one buffer applications can call the ioctl multiple times and thus
-	have multiple outstanding capture requests.
-
-	The ``VIDIOCSYNC`` ioctl suspends execution until a particular
-	buffer has been filled.
-      - Drivers maintain an incoming and outgoing queue.
-	:ref:`VIDIOC_QBUF` enqueues any empty buffer into
-	the incoming queue. Filled buffers are dequeued from the outgoing
-	queue with the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. To wait
-	until filled buffers become available this function,
-	:ref:`select() <func-select>` or :ref:`poll() <func-poll>` can
-	be used. The :ref:`VIDIOC_STREAMON` ioctl
-	must be called once after enqueuing one or more buffers to start
-	capturing. Its counterpart
-	:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` stops capturing and
-	dequeues all buffers from both queues. Applications can query the
-	signal status, if known, with the
-	:ref:`VIDIOC_ENUMINPUT` ioctl.
-
-
-For a more in-depth discussion of memory mapping and examples, see
-:ref:`mmap`.
-
-
-Reading Raw VBI Data
-====================
-
-Originally the V4L API did not specify a raw VBI capture interface, only
-the device file ``/dev/vbi`` was reserved for this purpose. The only
-driver supporting this interface was the BTTV driver, de-facto defining
-the V4L VBI interface. Reading from the device yields a raw VBI image
-with the following parameters:
-
-
-
-.. flat-table::
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - struct :c:type:`v4l2_vbi_format`
-      - V4L, BTTV driver
-    * - sampling_rate
-      - 28636363 Hz NTSC (or any other 525-line standard); 35468950 Hz PAL
-	and SECAM (625-line standards)
-    * - offset
-      - ?
-    * - samples_per_line
-      - 2048
-    * - sample_format
-      - V4L2_PIX_FMT_GREY. The last four bytes (a machine endianness
-	integer) contain a frame counter.
-    * - start[]
-      - 10, 273 NTSC; 22, 335 PAL and SECAM
-    * - count[]
-      - 16, 16 [#f9]_
-    * - flags
-      - 0
-
-
-Undocumented in the V4L specification, in Linux 2.3 the
-``VIDIOCGVBIFMT`` and ``VIDIOCSVBIFMT`` ioctls using struct
-``vbi_format`` were added to determine the VBI image
-parameters. These ioctls are only partially compatible with the V4L2 VBI
-interface specified in :ref:`raw-vbi`.
-
-An ``offset`` field does not exist, ``sample_format`` is supposed to be
-``VIDEO_PALETTE_RAW``, equivalent to ``V4L2_PIX_FMT_GREY``. The
-remaining fields are probably equivalent to struct
-:c:type:`v4l2_vbi_format`.
-
-Apparently only the Zoran (ZR 36120) driver implements these ioctls. The
-semantics differ from those specified for V4L2 in two ways. The
-parameters are reset on :ref:`open() <func-open>` and
-``VIDIOCSVBIFMT`` always returns an ``EINVAL`` error code if the parameters
-are invalid.
-
-
-Miscellaneous
-=============
-
-V4L2 has no equivalent of the ``VIDIOCGUNIT`` ioctl. Applications can
-find the VBI device associated with a video capture device (or vice
-versa) by reopening the device and requesting VBI data. For details see
-:ref:`open`.
-
-No replacement exists for ``VIDIOCKEY``, and the V4L functions for
-microcode programming. A new interface for MPEG compression and playback
-devices is documented in :ref:`extended-controls`.
-
-.. [#f1]
-   According to Documentation/admin-guide/devices.rst these should be symbolic links
-   to ``/dev/video0``. Note the original bttv interface is not
-   compatible with V4L or V4L2.
-
-.. [#f2]
-   According to ``Documentation/admin-guide/devices.rst`` a symbolic link to
-   ``/dev/radio0``.
-
-.. [#f3]
-   This is a custom format used by the BTTV driver, not one of the V4L2
-   standard formats.
-
-.. [#f4]
-   Presumably all V4L RGB formats are little-endian, although some
-   drivers might interpret them according to machine endianness. V4L2
-   defines little-endian, big-endian and red/blue swapped variants. For
-   details see :ref:`pixfmt-rgb`.
-
-.. [#f5]
-   ``VIDEO_PALETTE_YUV422`` and ``VIDEO_PALETTE_YUYV`` are the same
-   formats. Some V4L drivers respond to one, some to the other.
-
-.. [#f6]
-   Not to be confused with ``V4L2_PIX_FMT_YUV411P``, which is a planar
-   format.
-
-.. [#f7]
-   V4L explains this as: "RAW capture (BT848)"
-
-.. [#f8]
-   Not to be confused with ``V4L2_PIX_FMT_Y41P``, which is a packed
-   format.
-
-.. [#f9]
-   Old driver versions used different values, eventually the custom
-   ``BTTV_VBISIZE`` ioctl was added to query the correct values.

-************************************
-Streaming I/O (DMA buffer importing)
-************************************
-
-The DMABUF framework provides a generic method for sharing buffers
-between multiple devices. Device drivers that support DMABUF can export
-a DMA buffer to userspace as a file descriptor (known as the exporter
-role), import a DMA buffer from userspace using a file descriptor
-previously exported for a different or the same device (known as the
-importer role), or both. This section describes the DMABUF importer role
-API in V4L2.
-
-Refer to :ref:`DMABUF exporting <VIDIOC_EXPBUF>` for details about
-exporting V4L2 buffers as DMABUF file descriptors.
-
-Input and output devices support the streaming I/O method when the
-``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>` ioctl is set. Whether
-importing DMA buffers through DMABUF file descriptors is supported is
-determined by calling the :ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
-ioctl with the memory type set to ``V4L2_MEMORY_DMABUF``.
-
-This I/O method is dedicated to sharing DMA buffers between different
-devices, which may be V4L devices or other video-related devices (e.g.
-DRM). Buffers (planes) are allocated by a driver on behalf of an
-application. Next, these buffers are exported to the application as file
-descriptors using an API which is specific for an allocator driver. Only
-such file descriptor are exchanged. The descriptors and meta-information
-are passed in struct :c:type:`v4l2_buffer` (or in struct
-:c:type:`v4l2_plane` in the multi-planar API case). The
-driver must be switched into DMABUF I/O mode by calling the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>` with the desired buffer type.
-
-
-Example: Initiating streaming I/O with DMABUF file descriptors
-==============================================================
-
-.. code-block:: c
-
-    struct v4l2_requestbuffers reqbuf;
-
-    memset(&reqbuf, 0, sizeof (reqbuf));
-    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-    reqbuf.memory = V4L2_MEMORY_DMABUF;
-    reqbuf.count = 1;
-
-    if (ioctl(fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
-	if (errno == EINVAL)
-	    printf("Video capturing or DMABUF streaming is not supported\\n");
-	else
-	    perror("VIDIOC_REQBUFS");
-
-	exit(EXIT_FAILURE);
-    }
-
-The buffer (plane) file descriptor is passed on the fly with the
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. In case of multiplanar
-buffers, every plane can be associated with a different DMABUF
-descriptor. Although buffers are commonly cycled, applications can pass
-a different DMABUF descriptor at each :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call.
-
-Example: Queueing DMABUF using single plane API
-===============================================
-
-.. code-block:: c
-
-    int buffer_queue(int v4lfd, int index, int dmafd)
-    {
-	struct v4l2_buffer buf;
-
-	memset(&buf, 0, sizeof buf);
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-	buf.memory = V4L2_MEMORY_DMABUF;
-	buf.index = index;
-	buf.m.fd = dmafd;
-
-	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
-	    perror("VIDIOC_QBUF");
-	    return -1;
-	}
-
-	return 0;
-    }
-
-Example 3.6. Queueing DMABUF using multi plane API
-==================================================
-
-.. code-block:: c
-
-    int buffer_queue_mp(int v4lfd, int index, int dmafd[], int n_planes)
-    {
-	struct v4l2_buffer buf;
-	struct v4l2_plane planes[VIDEO_MAX_PLANES];
-	int i;
-
-	memset(&buf, 0, sizeof buf);
-	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
-	buf.memory = V4L2_MEMORY_DMABUF;
-	buf.index = index;
-	buf.m.planes = planes;
-	buf.length = n_planes;
-
-	memset(&planes, 0, sizeof planes);
-
-	for (i = 0; i < n_planes; ++i)
-	    buf.m.planes[i].m.fd = dmafd[i];
-
-	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
-	    perror("VIDIOC_QBUF");
-	    return -1;
-	}
-
-	return 0;
-    }
-
-Captured or displayed buffers are dequeued with the
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
-buffer at any time between the completion of the DMA and this ioctl. The
-memory is also unlocked when
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, or when the device is closed.
-
-For capturing applications it is customary to enqueue a number of empty
-buffers, to start capturing and enter the read loop. Here the
-application waits until a filled buffer can be dequeued, and re-enqueues
-the buffer when the data is no longer needed. Output applications fill
-and enqueue buffers, when enough buffers are stacked up output is
-started. In the write loop, when the application runs out of free
-buffers it must wait until an empty buffer can be dequeued and reused.
-Two methods exist to suspend execution of the application until one or
-more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
-<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
-``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
-error code when no buffer is available. The
-:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
-functions are always available.
-
-To start and stop capturing or displaying applications call the
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls.
-
-.. note::
-
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
-   both queues and unlocks all buffers as a side effect. Since there is no
-   notion of doing anything "now" on a multitasking system, if an
-   application needs to synchronize with another event it should examine
-   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
-   outputted buffers.
-
-Drivers implementing DMABUF importing I/O must support the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON
-<VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls,
-and the :ref:`select() <func-select>` and :ref:`poll() <func-poll>`
-functions.

-Digital Video (DV) Timings
-**************************
-
-The video standards discussed so far have been dealing with Analog TV
-and the corresponding video timings. Today there are many more different
-hardware interfaces such as High Definition TV interfaces (HDMI), VGA,
-DVI connectors etc., that carry video signals and there is a need to
-extend the API to select the video timings for these interfaces. Since
-it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>`
-due to the limited bits available, a new set of ioctls was added to
-set/get video timings at the input and output.
-
-These ioctls deal with the detailed digital video timings that define
-each video format. This includes parameters such as the active video
-width and height, signal polarities, frontporches, backporches, sync
-widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get
-the timings of the formats in the :ref:`cea861` and :ref:`vesadmt`
-standards.
-
-To enumerate and query the attributes of the DV timings supported by a
-device applications use the
-:ref:`VIDIOC_ENUM_DV_TIMINGS` and
-:ref:`VIDIOC_DV_TIMINGS_CAP` ioctls. To set
-DV timings for the device applications use the
-:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get
-current DV timings they use the
-:ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. To detect
-the DV timings as seen by the video receiver applications use the
-:ref:`VIDIOC_QUERY_DV_TIMINGS` ioctl.
-
-Applications can make use of the :ref:`input-capabilities` and
-:ref:`output-capabilities` flags to determine whether the digital
-video ioctls can be used with the given input or output.

-Camera Control IDs
-==================
-
-``V4L2_CID_CAMERA_CLASS (class)``
-    The Camera class descriptor. Calling
-    :ref:`VIDIOC_QUERYCTRL` for this control will
-    return a description of this control class.
-
-.. _v4l2-exposure-auto-type:
-
-``V4L2_CID_EXPOSURE_AUTO``
-    (enum)
-
-enum v4l2_exposure_auto_type -
-    Enables automatic adjustments of the exposure time and/or iris
-    aperture. The effect of manual changes of the exposure time or iris
-    aperture while these features are enabled is undefined, drivers
-    should ignore such requests. Possible values are:
-
-
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-
-    * - ``V4L2_EXPOSURE_AUTO``
-      - Automatic exposure time, automatic iris aperture.
-    * - ``V4L2_EXPOSURE_MANUAL``
-      - Manual exposure time, manual iris.
-    * - ``V4L2_EXPOSURE_SHUTTER_PRIORITY``
-      - Manual exposure time, auto iris.
-    * - ``V4L2_EXPOSURE_APERTURE_PRIORITY``
-      - Auto exposure time, manual iris.
-
-
-
-``V4L2_CID_EXPOSURE_ABSOLUTE (integer)``
-    Determines the exposure time of the camera sensor. The exposure time
-    is limited by the frame interval. Drivers should interpret the
-    values as 100 µs units, where the value 1 stands for 1/10000th of a
-    second, 10000 for 1 second and 100000 for 10 seconds.
-
-``V4L2_CID_EXPOSURE_AUTO_PRIORITY (boolean)``
-    When ``V4L2_CID_EXPOSURE_AUTO`` is set to ``AUTO`` or
-    ``APERTURE_PRIORITY``, this control determines if the device may
-    dynamically vary the frame rate. By default this feature is disabled
-    (0) and the frame rate must remain constant.
-
-``V4L2_CID_AUTO_EXPOSURE_BIAS (integer menu)``
-    Determines the automatic exposure compensation, it is effective only
-    when ``V4L2_CID_EXPOSURE_AUTO`` control is set to ``AUTO``,
-    ``SHUTTER_PRIORITY`` or ``APERTURE_PRIORITY``. It is expressed in
-    terms of EV, drivers should interpret the values as 0.001 EV units,
-    where the value 1000 stands for +1 EV.
-
-    Increasing the exposure compensation value is equivalent to
-    decreasing the exposure value (EV) and will increase the amount of
-    light at the image sensor. The camera performs the exposure
-    compensation by adjusting absolute exposure time and/or aperture.
-
-.. _v4l2-exposure-metering:
-
-``V4L2_CID_EXPOSURE_METERING``
-    (enum)
-
-enum v4l2_exposure_metering -

-    :header-rows:  0
-    :stub-columns: 0
-
-    * - ``V4L2_EXPOSURE_METERING_AVERAGE``
-      - Use the light information coming from the entire frame and average
-	giving no weighting to any particular portion of the metered area.
-    * - ``V4L2_EXPOSURE_METERING_CENTER_WEIGHTED``
-      - Average the light information coming from the entire frame giving
-	priority to the center of the metered area.
-    * - ``V4L2_EXPOSURE_METERING_SPOT``
-      - Measure only very small area at the center of the frame.
-    * - ``V4L2_EXPOSURE_METERING_MATRIX``
-      - A multi-zone metering. The light intensity is measured in several
-	points of the frame and the results are combined. The algorithm of
-	the zones selection and their significance in calculating the
-	final value is device dependent.
-
-
-
-``V4L2_CID_PAN_RELATIVE (integer)``
-    This control turns the camera horizontally by the specified amount.
-    The unit is undefined. A positive value moves the camera to the
-    right (clockwise when viewed from above), a negative value to the
-    left. A value of zero does not cause motion. This is a write-only
-    control.
-
-``V4L2_CID_TILT_RELATIVE (integer)``
-    This control turns the camera vertically by the specified amount.
-    The unit is undefined. A positive value moves the camera up, a

-    When this control is set, the camera moves horizontally to the
-    default position.
-
-``V4L2_CID_TILT_RESET (button)``
-    When this control is set, the camera moves vertically to the default
-    position.
-
-``V4L2_CID_PAN_ABSOLUTE (integer)``
-    This control turns the camera horizontally to the specified
-    position. Positive values move the camera to the right (clockwise
-    when viewed from above), negative values to the left. Drivers should
-    interpret the values as arc seconds, with valid values between -180
-    * 3600 and +180 * 3600 inclusive.
-
-``V4L2_CID_TILT_ABSOLUTE (integer)``
-    This control turns the camera vertically to the specified position.
-    Positive values move the camera up, negative values down. Drivers
-    should interpret the values as arc seconds, with valid values

-
-``V4L2_CID_FOCUS_AUTO (boolean)``
-    Enables continuous automatic focus adjustments. The effect of manual
-    focus adjustments while this feature is enabled is undefined,
-    drivers should ignore such requests.
-
-``V4L2_CID_AUTO_FOCUS_START (button)``
-    Starts single auto focus process. The effect of setting this control
-    when ``V4L2_CID_FOCUS_AUTO`` is set to ``TRUE`` (1) is undefined,
-    drivers should ignore such requests.
-
-``V4L2_CID_AUTO_FOCUS_STOP (button)``
-    Aborts automatic focusing started with ``V4L2_CID_AUTO_FOCUS_START``
-    control. It is effective only when the continuous autofocus is
-    disabled, that is when ``V4L2_CID_FOCUS_AUTO`` control is set to
-    ``FALSE`` (0).
-
-.. _v4l2-auto-focus-status:
-
-``V4L2_CID_AUTO_FOCUS_STATUS (bitmask)``
-    The automatic focus status. This is a read-only control.
-
-    Setting ``V4L2_LOCK_FOCUS`` lock bit of the ``V4L2_CID_3A_LOCK``

-	possible distance for auto focus.
-    * - ``V4L2_AUTO_FOCUS_RANGE_INFINITY``
-      - The lens is set to focus on an object at infinite distance.
-
-
-
-``V4L2_CID_ZOOM_ABSOLUTE (integer)``
-    Specify the objective lens focal length as an absolute value. The
-    zoom unit is driver-specific and its value should be a positive
-    integer.
-
-``V4L2_CID_ZOOM_RELATIVE (integer)``
-    Specify the objective lens focal length relatively to the current
-    value. Positive values move the zoom lens group towards the
-    telephoto direction, negative values towards the wide-angle
-    direction. The zoom unit is driver-specific. This is a write-only
-    control.
-
-``V4L2_CID_ZOOM_CONTINUOUS (integer)``
-    Move the objective lens group at the specified speed until it
-    reaches physical device limits or until an explicit request to stop
-    the movement. A positive value moves the zoom lens group towards the
-    telephoto direction. A value of zero stops the zoom lens group
-    movement. A negative value moves the zoom lens group towards the
-    wide-angle direction. The zoom speed unit is driver-specific.
-
-``V4L2_CID_IRIS_ABSOLUTE (integer)``
-    This control sets the camera's aperture to the specified value. The
-    unit is undefined. Larger values open the iris wider, smaller values
-    close it.
-
-``V4L2_CID_IRIS_RELATIVE (integer)``
-    This control modifies the camera's aperture by the specified amount.
-    The unit is undefined. Positive values open the iris one step
-    further, negative values close it one step further. This is a
-    write-only control.
-
-``V4L2_CID_PRIVACY (boolean)``
-    Prevent video from being acquired by the camera. When this control
-    is set to ``TRUE`` (1), no image can be captured by the camera.
-    Common means to enforce privacy are mechanical obturation of the
-    sensor and firmware image processing, but the device is not
-    restricted to these methods. Devices that implement the privacy
-    control must support read access and may support write access.
-
-``V4L2_CID_BAND_STOP_FILTER (integer)``
-    Switch the band-stop filter of a camera sensor on or off, or specify
-    its strength. Such band-stop filters can be used, for example, to
-    filter out the fluorescent light component.
-
-.. _v4l2-auto-n-preset-white-balance:
-
-``V4L2_CID_AUTO_N_PRESET_WHITE_BALANCE``
-    (enum)
-
-enum v4l2_auto_n_preset_white_balance -
-    Sets white balance to automatic, manual or a preset. The presets
-    determine color temperature of the light as a hint to the camera for
-    white balance adjustments resulting in most accurate color

-
-
-
-.. _v4l2-wide-dynamic-range:
-
-``V4L2_CID_WIDE_DYNAMIC_RANGE (boolean)``
-    Enables or disables the camera's wide dynamic range feature. This
-    feature allows to obtain clear images in situations where intensity
-    of the illumination varies significantly throughout the scene, i.e.
-    there are simultaneously very dark and very bright areas. It is most
-    commonly realized in cameras by combining two subsequent frames with
-    different exposure times.  [#f1]_
-
-.. _v4l2-image-stabilization:
-
-``V4L2_CID_IMAGE_STABILIZATION (boolean)``
-    Enables or disables image stabilization.
-
-``V4L2_CID_ISO_SENSITIVITY (integer menu)``
-    Determines ISO equivalent of an image sensor indicating the sensor's
-    sensitivity to light. The numbers are expressed in arithmetic scale,
-    as per :ref:`iso12232` standard, where doubling the sensor
-    sensitivity is represented by doubling the numerical ISO value.
-    Applications should interpret the values as standard ISO values
-    multiplied by 1000, e.g. control value 800 stands for ISO 0.8.
-    Drivers will usually support only a subset of standard ISO values.
-    The effect of setting this control while the
-    ``V4L2_CID_ISO_SENSITIVITY_AUTO`` control is set to a value other
-    than ``V4L2_CID_ISO_SENSITIVITY_MANUAL`` is undefined, drivers
-    should ignore such requests.

-
-
-.. _v4l2-scene-mode:
-
-``V4L2_CID_SCENE_MODE``
-    (enum)
-
-enum v4l2_scene_mode -
-    This control allows to select scene programs as the camera automatic
-    modes optimized for common shooting scenes. Within these modes the
-    camera determines best exposure, aperture, focusing, light metering,
-    white balance and equivalent sensitivity. The controls of those
-    parameters are influenced by the scene mode control. An exact
-    behavior in each mode is subject to the camera specification.
-
-    When the scene mode feature is not used, this control should be set
-    to ``V4L2_SCENE_MODE_NONE`` to make sure the other possibly related
-    controls are accessible. The following scene programs are defined:

-.. tabularcolumns:: |p{5.9cm}|p{11.5cm}|
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-
-    * - ``V4L2_SCENE_MODE_NONE``
-      - The scene mode feature is disabled.
-    * - ``V4L2_SCENE_MODE_BACKLIGHT``
-      - Backlight. Compensates for dark shadows when light is coming from
-	behind a subject, also by automatically turning on the flash.
-    * - ``V4L2_SCENE_MODE_BEACH_SNOW``
-      - Beach and snow. This mode compensates for all-white or bright
-	scenes, which tend to look gray and low contrast, when camera's
-	automatic exposure is based on an average scene brightness. To
-	compensate, this mode automatically slightly overexposes the
-	frames. The white balance may also be adjusted to compensate for
-	the fact that reflected snow looks bluish rather than white.
-    * - ``V4L2_SCENE_MODE_CANDLELIGHT``
-      - Candle light. The camera generally raises the ISO sensitivity and
-	lowers the shutter speed. This mode compensates for relatively
-	close subject in the scene. The flash is disabled in order to
-	preserve the ambiance of the light.
-    * - ``V4L2_SCENE_MODE_DAWN_DUSK``
-      - Dawn and dusk. Preserves the colors seen in low natural light
-	before dusk and after down. The camera may turn off the flash, and
-	automatically focus at infinity. It will usually boost saturation
-	and lower the shutter speed.
-    * - ``V4L2_SCENE_MODE_FALL_COLORS``
-      - Fall colors. Increases saturation and adjusts white balance for
-	color enhancement. Pictures of autumn leaves get saturated reds
-	and yellows.
-    * - ``V4L2_SCENE_MODE_FIREWORKS``
-      - Fireworks. Long exposure times are used to capture the expanding
-	burst of light from a firework. The camera may invoke image
-	stabilization.
-    * - ``V4L2_SCENE_MODE_LANDSCAPE``
-      - Landscape. The camera may choose a small aperture to provide deep
-	depth of field and long exposure duration to help capture detail
-	in dim light conditions. The focus is fixed at infinity. Suitable
-	for distant and wide scenery.
-    * - ``V4L2_SCENE_MODE_NIGHT``
-      - Night, also known as Night Landscape. Designed for low light
-	conditions, it preserves detail in the dark areas without blowing
-	out bright objects. The camera generally sets itself to a
-	medium-to-high ISO sensitivity, with a relatively long exposure
-	time, and turns flash off. As such, there will be increased image
-	noise and the possibility of blurred image.
-    * - ``V4L2_SCENE_MODE_PARTY_INDOOR``
-      - Party and indoor. Designed to capture indoor scenes that are lit
-	by indoor background lighting as well as the flash. The camera
-	usually increases ISO sensitivity, and adjusts exposure for the
-	low light conditions.
-    * - ``V4L2_SCENE_MODE_PORTRAIT``
-      - Portrait. The camera adjusts the aperture so that the depth of
-	field is reduced, which helps to isolate the subject against a
-	smooth background. Most cameras recognize the presence of faces in
-	the scene and focus on them. The color hue is adjusted to enhance
-	skin tones. The intensity of the flash is often reduced.
-    * - ``V4L2_SCENE_MODE_SPORTS``
-      - Sports. Significantly increases ISO and uses a fast shutter speed
-	to freeze motion of rapidly-moving subjects. Increased image noise
-	may be seen in this mode.
-    * - ``V4L2_SCENE_MODE_SUNSET``
-      - Sunset. Preserves deep hues seen in sunsets and sunrises. It bumps
-	up the saturation.
-    * - ``V4L2_SCENE_MODE_TEXT``
-      - Text. It applies extra contrast and sharpness, it is typically a
-	black-and-white mode optimized for readability. Automatic focus
-	may be switched to close-up mode and this setting may also involve
-	some lens-distortion correction.

-
-``V4L2_CID_3A_LOCK (bitmask)``
-    This control locks or unlocks the automatic focus, exposure and
-    white balance. The automatic adjustments can be paused independently
-    by setting the corresponding lock bit to 1. The camera then retains
-    the settings until the lock bit is cleared. The following lock bits
-    are defined:
-
-    When a given algorithm is not enabled, drivers should ignore
-    requests to lock it and should return no error. An example might be
-    an application setting bit ``V4L2_LOCK_WHITE_BALANCE`` when the
-    ``V4L2_CID_AUTO_WHITE_BALANCE`` control is set to ``FALSE``. The
-    value of this control may be changed by exposure, white balance or
-    focus controls.

-
-``V4L2_CID_PAN_SPEED (integer)``
-    This control turns the camera horizontally at the specific speed.
-    The unit is undefined. A positive value moves the camera to the
-    right (clockwise when viewed from above), a negative value to the
-    left. A value of zero stops the motion if one is in progress and has
-    no effect otherwise.
-
-``V4L2_CID_TILT_SPEED (integer)``

-    unit is undefined. A positive value moves the camera up, a negative
-    value down. A value of zero stops the motion if one is in progress
-    and has no effect otherwise.

-Codec Control Reference
-***********************
-
-Below all controls within the Codec control class are described. First
-the generic controls, then controls specific for certain hardware.
-
-.. note::
-
-   These controls are applicable to all codecs and not just MPEG. The
-   defines are prefixed with V4L2_CID_MPEG/V4L2_MPEG as the controls
-   were originally made for MPEG codecs and later extended to cover all
-   encoding formats.

-    Display delay value for H264 decoder. The decoder is forced to
-    return a decoded frame after the set 'display delay' number of
-    frames. If this number is low it may result in frames returned out
-    of display order, in addition the hardware may still be using the
-    returned buffer as a reference picture for subsequent frames.
-
-``V4L2_CID_MPEG_MFC51_VIDEO_H264_NUM_REF_PIC_FOR_P (integer)``

-    the average bitrate for a GOP and keep it below or equal the set
-    bitrate target. Otherwise the rate control logic calculates the
-    overall average bitrate for the stream and keeps it below or equal
-    to the set bitrate. In the first case the average bitrate for the
-    whole stream will be smaller then the set bitrate. This is caused
-    because the average is calculated for smaller number of frames, on

-   receive or transmit video from/to only one of those pads, the other pads
-   can still be active when it comes to EDID (Extended Display
-   Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
-   Content Protection System, :ref:`hdcp`) processing, allowing the
-   device to do the fairly slow EDID/HDCP handling in advance. This allows
-   for quick switching between connectors.
-
-These pads appear in several of the controls in this section as
-bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
-1, etc. The maximum value of the control is the set of valid pads.

-
-.. _dv-control-id:
-
-Digital Video Control IDs
-=========================
-
-``V4L2_CID_DV_CLASS (class)``
-    The Digital Video class descriptor.
-
-``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
-    Many connectors have a hotplug pin which is high if EDID information
-    is available from the source. This control shows the state of the
-    hotplug pin as seen by the transmitter. Each bit corresponds to an
-    output pad on the transmitter. If an output pad does not have an
-    associated hotplug pin, then the bit for that pad will be 0. This
-    read-only control is applicable to DVI-D, HDMI and DisplayPort
-    connectors.
-
-``V4L2_CID_DV_TX_RXSENSE (bitmask)``
-    Rx Sense is the detection of pull-ups on the TMDS clock lines. This
-    normally means that the sink has left/entered standby (i.e. the
-    transmitter can sense that the receiver is ready to receive video).
-    Each bit corresponds to an output pad on the transmitter. If an
-    output pad does not have an associated Rx Sense, then the bit for
-    that pad will be 0. This read-only control is applicable to DVI-D
-    and HDMI devices.
-
-``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
-    When the transmitter sees the hotplug signal from the receiver it
-    will attempt to read the EDID. If set, then the transmitter has read
-    at least the first block (= 128 bytes). Each bit corresponds to an
-    output pad on the transmitter. If an output pad does not support
-    EDIDs, then the bit for that pad will be 0. This read-only control
-    is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
-
-``V4L2_CID_DV_TX_MODE``
-    (enum)
-
-enum v4l2_dv_tx_mode -
-    HDMI transmitters can transmit in DVI-D mode (just video) or in HDMI
-    mode (video + audio + auxiliary data). This control selects which
-    mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
-    This control is applicable to HDMI connectors.
-
-``V4L2_CID_DV_TX_RGB_RANGE``
-    (enum)
-
-enum v4l2_dv_rgb_range -
-    Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO
-    follows the RGB quantization range specified in the standard for the
-    video interface (ie. :ref:`cea861` for HDMI).
-    V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
-    standard to be compatible with sinks that have not implemented the
-    standard correctly (unfortunately quite common for HDMI and DVI-D).
-    Full range allows all possible values to be used whereas limited
-    range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
-    the number of bits per component. This control is applicable to VGA,
-    DVI-A/D, HDMI and DisplayPort connectors.
-
-``V4L2_CID_DV_TX_IT_CONTENT_TYPE``
-    (enum)
-
-enum v4l2_dv_it_content_type -
-    Configures the IT Content Type of the transmitted video. This
-    information is sent over HDMI and DisplayPort connectors as part of
-    the AVI InfoFrame. The term 'IT Content' is used for content that
-    originates from a computer as opposed to content from a TV broadcast
-    or an analog source. The enum v4l2_dv_it_content_type defines
-    the possible content types:
-
-.. tabularcolumns:: |p{7.3cm}|p{10.4cm}|
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-
-    * - ``V4L2_DV_IT_CONTENT_TYPE_GRAPHICS``
-      - Graphics content. Pixel data should be passed unfiltered and
-	without analog reconstruction.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_PHOTO``
-      - Photo content. The content is derived from digital still pictures.
-	The content should be passed through with minimal scaling and
-	picture enhancements.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_CINEMA``
-      - Cinema content.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_GAME``
-      - Game content. Audio and video latency should be minimized.
-    * - ``V4L2_DV_IT_CONTENT_TYPE_NO_ITC``
-      - No IT Content information is available and the ITC bit in the AVI
-	InfoFrame is set to 0.
-
-
-
-``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
-    Detects whether the receiver receives power from the source (e.g.
-    HDMI carries 5V on one of the pins). This is often used to power an
-    eeprom which contains EDID information, such that the source can
-    read the EDID even if the sink is in standby/power off. Each bit
-    corresponds to an input pad on the receiver. If an input pad
-    cannot detect whether power is present, then the bit for that pad
-    will be 0. This read-only control is applicable to DVI-D, HDMI and
-    DisplayPort connectors.
-
-``V4L2_CID_DV_RX_RGB_RANGE``
-    (enum)
-
-enum v4l2_dv_rgb_range -
-    Select the quantization range for RGB input. V4L2_DV_RANGE_AUTO
-    follows the RGB quantization range specified in the standard for the

-***********************
-Flash Control Reference
-***********************
-
-The V4L2 flash controls are intended to provide generic access to flash
-controller devices. Flash controller devices are typically used in
-digital cameras.
-
-The interface can support both LED and xenon flash devices. As of
-writing this, there is no xenon flash driver using this interface.
-
-
-.. _flash-controls-use-cases:
-
-Supported use cases
-===================
-
-
-Unsynchronised LED flash (software strobe)
-------------------------------------------
-
-Unsynchronised LED flash is controlled directly by the host as the
-sensor. The flash must be enabled by the host before the exposure of the
-image starts and disabled once it ends. The host is fully responsible
-for the timing of the flash.
-
-Example of such device: Nokia N900.
-
-
-Synchronised LED flash (hardware strobe)
-----------------------------------------
-
-The synchronised LED flash is pre-programmed by the host (power and
-timeout) but controlled by the sensor through a strobe signal from the
-sensor to the flash.
-
-The sensor controls the flash duration and timing. This information
-typically must be made available to the sensor.
-
-
-LED flash as torch
-------------------
-
-LED flash may be used as torch in conjunction with another use case
-involving camera or individually.
-
-
-.. _flash-control-id:
-
-Flash Control IDs
------------------
-
-``V4L2_CID_FLASH_CLASS (class)``
-    The FLASH class descriptor.
-
-``V4L2_CID_FLASH_LED_MODE (menu)``
-    Defines the mode of the flash LED, the high-power white LED attached
-    to the flash controller. Setting this control may not be possible in
-    presence of some faults. See V4L2_CID_FLASH_FAULT.
-
-

-      - Flash mode.
-    * - ``V4L2_FLASH_LED_MODE_TORCH``
-      - Torch mode. See V4L2_CID_FLASH_TORCH_INTENSITY.
-
-
-
-``V4L2_CID_FLASH_STROBE_SOURCE (menu)``
-    Defines the source of the flash LED strobe.
-
-.. tabularcolumns:: |p{7.5cm}|p{10.0cm}|
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-
-    * - ``V4L2_FLASH_STROBE_SOURCE_SOFTWARE``
-      - The flash strobe is triggered by using the
-	V4L2_CID_FLASH_STROBE control.
-    * - ``V4L2_FLASH_STROBE_SOURCE_EXTERNAL``
-      - The flash strobe is triggered by an external source. Typically
-	this is a sensor, which makes it possible to synchronise the
-	flash strobe start to exposure start.
-
-
-
-``V4L2_CID_FLASH_STROBE (button)``
-    Strobe flash. Valid when V4L2_CID_FLASH_LED_MODE is set to
-    V4L2_FLASH_LED_MODE_FLASH and V4L2_CID_FLASH_STROBE_SOURCE
-    is set to V4L2_FLASH_STROBE_SOURCE_SOFTWARE. Setting this
-    control may not be possible in presence of some faults. See
-    V4L2_CID_FLASH_FAULT.
-
-``V4L2_CID_FLASH_STROBE_STOP (button)``
-    Stop flash strobe immediately.
-
-``V4L2_CID_FLASH_STROBE_STATUS (boolean)``
-    Strobe status: whether the flash is strobing at the moment or not.
-    This is a read-only control.
-
-``V4L2_CID_FLASH_TIMEOUT (integer)``
-    Hardware timeout for flash. The flash strobe is stopped after this
-    period of time has passed from the start of the strobe.
-
-``V4L2_CID_FLASH_INTENSITY (integer)``
-    Intensity of the flash strobe when the flash LED is in flash mode
-    (V4L2_FLASH_LED_MODE_FLASH). The unit should be milliamps (mA)

-    Intensity of the flash LED in torch mode
-    (V4L2_FLASH_LED_MODE_TORCH). The unit should be milliamps (mA)
-    if possible. Setting this control may not be possible in presence of
-    some faults. See V4L2_CID_FLASH_FAULT.
-
-``V4L2_CID_FLASH_INDICATOR_INTENSITY (integer)``
-    Intensity of the indicator LED. The indicator LED may be fully
-    independent of the flash LED. The unit should be microamps (uA) if
-    possible.
-
-``V4L2_CID_FLASH_FAULT (bitmask)``
-    Faults related to the flash. The faults tell about specific problems
-    in the flash chip itself or the LEDs attached to it. Faults may
-    prevent further use of some of the flash controls. In particular,
-    V4L2_CID_FLASH_LED_MODE is set to V4L2_FLASH_LED_MODE_NONE
-    if the fault affects the flash LED. Exactly which faults have such
-    an effect is chip dependent. Reading the faults resets the control
-    and returns the chip to a usable state if possible.

-      - The flash controller has detected a short or open circuit
-	condition on the indicator LED.
-    * - ``V4L2_FLASH_FAULT_UNDER_VOLTAGE``
-      - Flash controller voltage to the flash LED has been below the
-	minimum limit specific to the flash controller.
-    * - ``V4L2_FLASH_FAULT_INPUT_VOLTAGE``
-      - The input voltage of the flash controller is below the limit under
-	which strobing the flash at full current will not be possible.The
-	condition persists until this flag is no longer set.
-    * - ``V4L2_FLASH_FAULT_LED_OVER_TEMPERATURE``
-      - The temperature of the LED has exceeded its allowed upper limit.
-

-    The FM_RX class descriptor. Calling
-    :ref:`VIDIOC_QUERYCTRL` for this control will
-    return a description of this control class.
-
-``V4L2_CID_RDS_RECEPTION (boolean)``
-    Enables/disables RDS reception by the radio tuner
-
-``V4L2_CID_RDS_RX_PTY (integer)``
-    Gets RDS Programme Type field. This encodes up to 31 pre-defined
-    programme types.
-
-``V4L2_CID_RDS_RX_PS_NAME (string)``
-    Gets the Programme Service name (PS_NAME). It is intended for
-    static display on a receiver. It is the primary aid to listeners in
-    programme service identification and selection. In Annex E of
-    :ref:`iec62106`, the RDS specification, there is a full
-    description of the correct character encoding for Programme Service
-    name strings. Also from RDS specification, PS is usually a single
-    eight character text. However, it is also possible to find receivers
-    which can scroll strings sized as 8 x N characters. So, this control
-    must be configured with steps of 8 characters. The result is it must
-    always contain a string with size multiple of 8.
-
-``V4L2_CID_RDS_RX_RADIO_TEXT (string)``
-    Gets the Radio Text info. It is a textual description of what is
-    being broadcasted. RDS Radio Text can be applied when broadcaster
-    wishes to transmit longer PS names, programme-related information or
-    any other text. In these cases, RadioText can be used in addition to
-    ``V4L2_CID_RDS_RX_PS_NAME``. The encoding for Radio Text strings is
-    also fully described in Annex E of :ref:`iec62106`. The length of
-    Radio Text strings depends on which RDS Block is being used to
-    transmit it, either 32 (2A block) or 64 (2B block). However, it is
-    also possible to find receivers which can scroll strings sized as 32
-    x N or 64 x N characters. So, this control must be configured with
-    steps of 32 or 64 characters. The result is it must always contain a
-    string with size multiple of 32 or 64.
-
-``V4L2_CID_RDS_RX_TRAFFIC_ANNOUNCEMENT (boolean)``
-    If set, then a traffic announcement is in progress.
-
-``V4L2_CID_RDS_RX_TRAFFIC_PROGRAM (boolean)``
-    If set, then the tuned programme carries traffic announcements.
-
-``V4L2_CID_RDS_RX_MUSIC_SPEECH (boolean)``
-    If set, then this channel broadcasts music. If cleared, then it
-    broadcasts speech. If the transmitter doesn't make this distinction,
-    then it will be set.
-
-``V4L2_CID_TUNE_DEEMPHASIS``
-    (enum)
-
-enum v4l2_deemphasis -
-    Configures the de-emphasis value for reception. A de-emphasis filter
-    is applied to the broadcast to accentuate the high audio
-    frequencies. Depending on the region, a time constant of either 50
-    or 75 useconds is used. The enum v4l2_deemphasis defines possible
-    values for de-emphasis. Here they are:

-``V4L2_CID_IMAGE_PROC_CLASS (class)``
-    The IMAGE_PROC class descriptor.
-
-``V4L2_CID_LINK_FREQ (integer menu)``
-    Data bus frequency. Together with the media bus pixel code, bus type
-    (clock cycles per sample), the data bus frequency defines the pixel
-    rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
-    elsewhere, if the device is not an image sensor). The frame rate can
-    be calculated from the pixel clock, image width and height and
-    horizontal and vertical blanking. While the pixel rate control may
-    be defined elsewhere than in the subdev containing the pixel array,
-    the frame rate cannot be obtained from that information. This is
-    because only on the pixel array it can be assumed that the vertical
-    and horizontal blanking information is exact: no other blanking is
-    allowed in the pixel array. The selection of frame rate is performed
-    by selecting the desired horizontal and vertical blanking. The unit
-    of this control is Hz.
-
-``V4L2_CID_PIXEL_RATE (64-bit integer)``
-    Pixel rate in the source pads of the subdev. This control is
-    read-only and its unit is pixels / second.
-
-``V4L2_CID_TEST_PATTERN (menu)``
-    Some capture/display/sensor devices have the capability to generate
-    test pattern images. These hardware specific test patterns can be
-    used to test if a device is working properly.
-
-``V4L2_CID_DEINTERLACING_MODE (menu)``
-    The video deinterlacing mode (such as Bob, Weave, ...). The menu items are
-    driver specific and are documented in :ref:`v4l-drivers`.
-
-``V4L2_CID_DIGITAL_GAIN (integer)``
-    Digital gain is the value by which all colour components
-    are multiplied by. Typically the digital gain applied is the
-    control value divided by e.g. 0x100, meaning that to get no
-    digital gain the control value needs to be 0x100. The no-gain
-    configuration is also typically the default.

-
-The RF Tuner (RF_TUNER) class includes controls for common features of

-
-In this context, RF tuner is radio receiver circuit between antenna and
-demodulator. It receives radio frequency (RF) from the antenna and
-converts that received signal to lower intermediate frequency (IF) or
-baseband frequency (BB). Tuners that could do baseband output are often
-called Zero-IF tuners. Older tuners were typically simple PLL tuners
-inside a metal box, while newer ones are highly integrated chips
-without a metal box "silicon tuners". These controls are mostly
-applicable for new feature rich silicon tuners, just because older
-tuners does not have much adjustable features.

-Introduction
-============
-
-The control mechanism as originally designed was meant to be used for
-user settings (brightness, saturation, etc). However, it turned out to
-be a very useful model for implementing more complicated driver APIs
-where each driver implements only a subset of a larger API.
-
-The MPEG encoding API was the driving force behind designing and
-implementing this extended control mechanism: the MPEG standard is quite
-large and the currently supported hardware MPEG encoders each only
-implement a subset of this standard. Further more, many parameters
-relating to how the video is encoded into an MPEG stream are specific to
-the MPEG encoding chip since the MPEG standard only defines the format
-of the resulting MPEG stream, not how the video is actually encoded into
-that format.
-
-Unfortunately, the original control API lacked some features needed for
-these new uses and so it was extended into the (not terribly originally
-named) extended control API.
-
-Even though the MPEG encoding API was the first effort to use the
-Extended Control API, nowadays there are also other classes of Extended
-Controls, such as Camera Controls and FM Transmitter Controls. The
-Extended Controls API as well as all Extended Controls classes are
-described in the following text.
-
-
-The Extended Control API
-========================
-
-Three new ioctls are available:
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`. These ioctls act
-on arrays of controls (as opposed to the
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls that act on a single
-control). This is needed since it is often required to atomically change
-several controls at once.
-
-Each of the new ioctls expects a pointer to a struct
-:c:type:`v4l2_ext_controls`. This structure
-contains a pointer to the control array, a count of the number of
-controls in that array and a control class. Control classes are used to
-group similar controls into a single class. For example, control class
-``V4L2_CTRL_CLASS_USER`` contains all user controls (i. e. all controls
-that can also be set using the old :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
-ioctl). Control class ``V4L2_CTRL_CLASS_MPEG`` contains all controls
-relating to MPEG encoding, etc.
-
-All controls in the control array must belong to the specified control
-class. An error is returned if this is not the case.
-
-It is also possible to use an empty control array (``count`` == 0) to check
-whether the specified control class is supported.
-
-The control array is a struct
-:c:type:`v4l2_ext_control` array. The
-struct :c:type:`v4l2_ext_control` is very similar to
-struct :c:type:`v4l2_control`, except for the fact that
-it also allows for 64-bit values and pointers to be passed.
-
-Since the struct :c:type:`v4l2_ext_control` supports
-pointers it is now also possible to have controls with compound types
-such as N-dimensional arrays and/or structures. You need to specify the
-``V4L2_CTRL_FLAG_NEXT_COMPOUND`` when enumerating controls to actually
-be able to see such compound controls. In other words, these controls
-with compound types should only be used programmatically.
-
-Since such compound controls need to expose more information about
-themselves than is possible with :ref:`VIDIOC_QUERYCTRL <VIDIOC_QUERYCTRL>`
-the :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>` ioctl was added. In
-particular, this ioctl gives the dimensions of the N-dimensional array if
-this control consists of more than one element.
-
-.. note::
-
-   #. It is important to realize that due to the flexibility of controls it is
-      necessary to check whether the control you want to set actually is
-      supported in the driver and what the valid range of values is. So use
-      :ref:`VIDIOC_QUERYCTRL` to check this.
-
-   #. It is possible that some of the menu indices in a control of
-      type ``V4L2_CTRL_TYPE_MENU`` may not be supported (``VIDIOC_QUERYMENU``
-      will return an error). A good example is the list of supported MPEG
-      audio bitrates. Some drivers only support one or two bitrates, others
-      support a wider range.
-
-All controls use machine endianness.
-
-
-Enumerating Extended Controls
-=============================
-
-The recommended way to enumerate over the extended controls is by using
-:ref:`VIDIOC_QUERYCTRL` in combination with the
-``V4L2_CTRL_FLAG_NEXT_CTRL`` flag:
-
-
-.. code-block:: c
-
-    struct v4l2_queryctrl qctrl;
-
-    qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
-    while (0 == ioctl (fd, VIDIOC_QUERYCTRL, &qctrl)) {
-	/* ... */
-	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-    }
-
-The initial control ID is set to 0 ORed with the
-``V4L2_CTRL_FLAG_NEXT_CTRL`` flag. The ``VIDIOC_QUERYCTRL`` ioctl will
-return the first control with a higher ID than the specified one. When
-no such controls are found an error is returned.
-
-If you want to get all controls within a specific control class, then
-you can set the initial ``qctrl.id`` value to the control class and add
-an extra check to break out of the loop when a control of another
-control class is found:
-
-
-.. code-block:: c
-
-    qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
-    while (0 == ioctl(fd, VIDIOC_QUERYCTRL, &qctrl)) {
-	if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
-	    break;
-	/* ... */
-	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
-    }
-
-The 32-bit ``qctrl.id`` value is subdivided into three bit ranges: the
-top 4 bits are reserved for flags (e. g. ``V4L2_CTRL_FLAG_NEXT_CTRL``)
-and are not actually part of the ID. The remaining 28 bits form the
-control ID, of which the most significant 12 bits define the control
-class and the least significant 16 bits identify the control within the
-control class. It is guaranteed that these last 16 bits are always
-non-zero for controls. The range of 0x1000 and up are reserved for
-driver-specific controls. The macro ``V4L2_CTRL_ID2CLASS(id)`` returns
-the control class ID based on a control ID.
-
-If the driver does not support extended controls, then
-``VIDIOC_QUERYCTRL`` will fail when used in combination with
-``V4L2_CTRL_FLAG_NEXT_CTRL``. In that case the old method of enumerating
-control should be used (see :ref:`enum_all_controls`). But if it is
-supported, then it is guaranteed to enumerate over all controls,
-including driver-private controls.
-
-
-Creating Control Panels
-=======================
-
-It is possible to create control panels for a graphical user interface
-where the user can select the various controls. Basically you will have
-to iterate over all controls using the method described above. Each
-control class starts with a control of type
-``V4L2_CTRL_TYPE_CTRL_CLASS``. ``VIDIOC_QUERYCTRL`` will return the name
-of this control class which can be used as the title of a tab page
-within a control panel.
-
-The flags field of struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` also
-contains hints on the behavior of the control. See the
-:ref:`VIDIOC_QUERYCTRL` documentation for more
-details.

-
-***********
-Field Order
-***********
-
-We have to distinguish between progressive and interlaced video.
-Progressive video transmits all lines of a video image sequentially.
-Interlaced video divides an image into two fields, containing only the
-odd and even lines of the image, respectively. Alternating the so called
-odd and even field are transmitted, and due to a small delay between
-fields a cathode ray TV displays the lines interleaved, yielding the
-original frame. This curious technique was invented because at refresh
-rates similar to film the image would fade out too quickly. Transmitting
-fields reduces the flicker without the necessity of doubling the frame
-rate and with it the bandwidth required for each channel.
-
-It is important to understand a video camera does not expose one frame
-at a time, merely transmitting the frames separated into fields. The
-fields are in fact captured at two different instances in time. An
-object on screen may well move between one field and the next. For
-applications analysing motion it is of paramount importance to recognize
-which field of a frame is older, the *temporal order*.
-
-When the driver provides or accepts images field by field rather than
-interleaved, it is also important applications understand how the fields
-combine to frames. We distinguish between top (aka odd) and bottom (aka
-even) fields, the *spatial order*: The first line of the top field is
-the first line of an interlaced frame, the first line of the bottom
-field is the second line of that frame.
-
-However because fields were captured one after the other, arguing
-whether a frame commences with the top or bottom field is pointless. Any
-two successive top and bottom, or bottom and top fields yield a valid
-frame. Only when the source was progressive to begin with, e. g. when
-transferring film to video, two fields may come from the same frame,
-creating a natural order.
-
-Counter to intuition the top field is not necessarily the older field.
-Whether the older field contains the top or bottom lines is a convention
-determined by the video standard. Hence the distinction between temporal
-and spatial order of fields. The diagrams below should make this
-clearer.
-
-In V4L it is assumed that all video cameras transmit fields on the media
-bus in the same order they were captured, so if the top field was
-captured first (is the older field), the top field is also transmitted
-first on the bus.
-
-All video capture and output devices must report the current field
-order. Some drivers may permit the selection of a different order, to
-this end applications initialize the ``field`` field of struct
-:c:type:`v4l2_pix_format` before calling the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. If this is not desired it
-should have the value ``V4L2_FIELD_ANY`` (0).

-enum v4l2_field
-===============
-
-.. c:type:: v4l2_field
-
-.. tabularcolumns:: |p{5.8cm}|p{0.6cm}|p{11.1cm}|
-
-.. cssclass:: longtable
-
-.. flat-table::
-    :header-rows:  0
-    :stub-columns: 0
-    :widths:       3 1 4
-
-    * - ``V4L2_FIELD_ANY``
-      - 0
-      - Applications request this field order when any field format
-	is acceptable. Drivers choose depending on hardware capabilities or
-	e.g. the requested image size, and return the actual field order.
-	Drivers must never return ``V4L2_FIELD_ANY``.
-	If multiple field orders are possible the
-	driver must choose one of the possible field orders during
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
-	:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`. struct
-	:c:type:`v4l2_buffer` ``field`` can never be
-	``V4L2_FIELD_ANY``.
-    * - ``V4L2_FIELD_NONE``
-      - 1
-      - Images are in progressive (frame-based) format, not interlaced
-        (field-based).
-    * - ``V4L2_FIELD_TOP``
-      - 2
-      - Images consist of the top (aka odd) field only.
-    * - ``V4L2_FIELD_BOTTOM``
-      - 3
-      - Images consist of the bottom (aka even) field only. Applications
-	may wish to prevent a device from capturing interlaced images
-	because they will have "comb" or "feathering" artefacts around
-	moving objects.
-    * - ``V4L2_FIELD_INTERLACED``
-      - 4
-      - Images contain both fields, interleaved line by line. The temporal
-	order of the fields (whether the top or bottom field is older)
-	depends on the current video standard. In M/NTSC the bottom
-	field is the older field. In all other standards the top field
-	is the older field.
-    * - ``V4L2_FIELD_SEQ_TB``
-      - 5
-      - Images contain both fields, the top field lines are stored first
-	in memory, immediately followed by the bottom field lines. Fields
-	are always stored in temporal order, the older one first in
-	memory. Image sizes refer to the frame, not fields.
-    * - ``V4L2_FIELD_SEQ_BT``
-      - 6
-      - Images contain both fields, the bottom field lines are stored
-	first in memory, immediately followed by the top field lines.
-	Fields are always stored in temporal order, the older one first in
-	memory. Image sizes refer to the frame, not fields.
-    * - ``V4L2_FIELD_ALTERNATE``
-      - 7
-      - The two fields of a frame are passed in separate buffers, in
-	temporal order, i. e. the older one first. To indicate the field
-	parity (whether the current field is a top or bottom field) the
-	driver or application, depending on data direction, must set
-	struct :c:type:`v4l2_buffer` ``field`` to
-	``V4L2_FIELD_TOP`` or ``V4L2_FIELD_BOTTOM``. Any two successive
-	fields pair to build a frame. If fields are successive, without
-	any dropped fields between them (fields can drop individually),
-	can be determined from the struct
-	:c:type:`v4l2_buffer` ``sequence`` field. This
-	format cannot be selected when using the read/write I/O method
-	since there is no way to communicate if a field was a top or
-	bottom field.
-    * - ``V4L2_FIELD_INTERLACED_TB``
-      - 8
-      - Images contain both fields, interleaved line by line, top field
-	first. The top field is the older field.
-    * - ``V4L2_FIELD_INTERLACED_BT``
-      - 9
-      - Images contain both fields, interleaved line by line, top field
-	first. The bottom field is the older field.

-
-Data Format Negotiation
-=======================
-
-Different devices exchange different kinds of data with applications,
-for example video images, raw or sliced VBI data, RDS datagrams. Even
-within one kind many different formats are possible, in particular there is an
-abundance of image formats. Although drivers must provide a default and
-the selection persists across closing and reopening a device,
-applications should always negotiate a data format before engaging in
-data exchange. Negotiation means the application asks for a particular
-format and the driver selects and reports the best the hardware can do
-to satisfy the request. Of course applications can also just query the
-current selection.
-
-A single mechanism exists to negotiate all data formats using the
-aggregate struct :c:type:`v4l2_format` and the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls. Additionally the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to examine
-what the hardware *could* do, without actually selecting a new data
-format. The data formats supported by the V4L2 API are covered in the
-respective device section in :ref:`devices`. For a closer look at
-image formats see :ref:`pixfmt`.
-
-The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl is a major turning-point in the
-initialization sequence. Prior to this point multiple panel applications
-can access the same device concurrently to select the current input,
-change controls or modify other properties. The first :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-assigns a logical stream (video data, VBI data etc.) exclusively to one
-file descriptor.
-
-Exclusive means no other application, more precisely no other file
-descriptor, can grab this stream or change device properties
-inconsistent with the negotiated parameters. A video standard change for
-example, when the new standard uses a different number of scan lines,
-can invalidate the selected image format. Therefore only the file
-descriptor owning the stream can make invalidating changes. Accordingly
-multiple file descriptors which grabbed different logical streams
-prevent each other from interfering with their settings. When for
-example video overlay is about to start or already in progress,
-simultaneous video capturing may be restricted to the same cropping and
-image size.
-
-When applications omit the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl its locking side
-effects are implied by the next step, the selection of an I/O method
-with the :ref:`VIDIOC_REQBUFS` ioctl or implicit
-with the first :ref:`read() <func-read>` or
-:ref:`write() <func-write>` call.
-
-Generally only one logical stream can be assigned to a file descriptor,
-the exception being drivers permitting simultaneous video capturing and
-overlay using the same file descriptor for compatibility with V4L and
-earlier versions of V4L2. Switching the logical stream or returning into
-"panel mode" is possible by closing and reopening the device. Drivers
-*may* support a switch using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
-
-All drivers exchanging data with applications must support the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. Implementation of the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is highly recommended but optional.
-
-
-Image Format Enumeration
-========================
-
-Apart of the generic format negotiation functions a special ioctl to
-enumerate all image formats supported by video capture, overlay or
-output devices is available. [#f1]_
-
-The :ref:`VIDIOC_ENUM_FMT` ioctl must be supported
-by all drivers exchanging image data with applications.
-
-.. important::
-
-    Drivers are not supposed to convert image formats in kernel space.
-    They must enumerate only formats directly supported by the hardware.
-    If necessary driver writers should publish an example conversion

-
-``request``
-    V4L2 ioctl request code as defined in the ``videodev2.h`` header

-    Pointer to a function parameter, usually a structure.
-
-
-Description
-===========
-
-The :ref:`ioctl() <func-ioctl>` function is used to program V4L2 devices. The
-argument ``fd`` must be an open file descriptor. An ioctl ``request``
-has encoded in it whether the argument is an input, output or read/write
-parameter, and the size of the argument ``argp`` in bytes. Macros and
-defines specifying V4L2 ioctl requests are located in the
-``videodev2.h`` header file. Applications should use their own copy, not
-include the version in the kernel sources on the system they compile on.
-All V4L2 ioctl requests, their respective function and parameters are
-specified in :ref:`user-func`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-When an ioctl that takes an output or read/write parameter fails, the
-parameter remains unmodified.

-v4l2-mmap - Map device memory into application address space
-

-Synopsis
-========
-
-.. code-block:: c
-
-    #include <unistd.h>
-    #include <sys/mman.h>
-
-
-.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
-    :name: v4l2-mmap
-
-Arguments
-=========
-
-``start``
-    Map the buffer to this address in the application's address space.
-    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
-    multiple of the pagesize and mmap will fail when the specified
-    address cannot be used. Use of this option is discouraged;
-    applications should just specify a ``NULL`` pointer here.
-
-``length``
-    Length of the memory area to map. This must be the same value as
-    returned by the driver in the struct
-    :c:type:`v4l2_buffer` ``length`` field for the
-    single-planar API, and the same value as returned by the driver in
-    the struct :c:type:`v4l2_plane` ``length`` field for
-    the multi-planar API.
-
-``prot``
-    The ``prot`` argument describes the desired memory protection.
-    Regardless of the device type and the direction of data exchange it
-    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
-    and write access to image buffers. Drivers should support at least
-    this combination of flags.
-
-    .. note::
-
-      #. The Linux ``videobuf`` kernel module, which is used by some
-	 drivers supports only ``PROT_READ`` | ``PROT_WRITE``. When the
-	 driver does not support the desired protection, the
-	 :ref:`mmap() <func-mmap>` function fails.
-
-      #. Device memory accesses (e. g. the memory on a graphics card
-	 with video capturing hardware) may incur a performance penalty
-	 compared to main memory accesses, or reads may be significantly
-	 slower than writes or vice versa. Other I/O methods may be more
-	 efficient in such case.
-
-``flags``
-    The ``flags`` parameter specifies the type of the mapped object,
-    mapping options and whether modifications made to the mapped copy of
-    the page are private to the process or are to be shared with other
-    references.
-
-    ``MAP_FIXED`` requests that the driver selects no other address than
-    the one specified. If the specified address cannot be used,
-    :ref:`mmap() <func-mmap>` will fail. If ``MAP_FIXED`` is specified,
-    ``start`` must be a multiple of the pagesize. Use of this option is
-    discouraged.
-
-    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
-    ``MAP_SHARED`` allows applications to share the mapped memory with
-    other (e. g. child-) processes.
-
-    .. note::
-
-       The Linux ``videobuf`` module  which is used by some
-       drivers supports only ``MAP_SHARED``. ``MAP_PRIVATE`` requests
-       copy-on-write semantics. V4L2 applications should not set the
-       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
-       flags.
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``offset``
-    Offset of the buffer in device memory. This must be the same value
-    as returned by the driver in the struct
-    :c:type:`v4l2_buffer` ``m`` union ``offset`` field for
-    the single-planar API, and the same value as returned by the driver
-    in the struct :c:type:`v4l2_plane` ``m`` union
-    ``mem_offset`` field for the multi-planar API.
-
-
-Description
-===========
-
-The :ref:`mmap() <func-mmap>` function asks to map ``length`` bytes starting at
-``offset`` in the memory of the device specified by ``fd`` into the
-application address space, preferably at address ``start``. This latter
-address is a hint only, and is usually specified as 0.
-
-Suitable length and offset parameters are queried with the
-:ref:`VIDIOC_QUERYBUF` ioctl. Buffers must be
-allocated with the :ref:`VIDIOC_REQBUFS` ioctl
-before they can be queried.
-
-To unmap buffers the :ref:`munmap() <func-munmap>` function is used.
-
-
-Return Value
-============
-
-On success :ref:`mmap() <func-mmap>` returns a pointer to the mapped buffer. On
-error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
-appropriately. Possible error codes are:
-
-EBADF
-    ``fd`` is not a valid file descriptor.
-
-EACCES
-    ``fd`` is not open for reading and writing.
-
-EINVAL
-    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
-    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
-
-    The ``flags`` or ``prot`` value is not supported.
-
-    No buffers have been allocated with the
-    :ref:`VIDIOC_REQBUFS` ioctl.
-
-ENOMEM
-    Not enough physical or virtual memory was available to complete the
-    request.

-Synopsis
-========
-
-.. code-block:: c
-
-    #include <sys/poll.h>
-
-
-.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
-    :name: v4l2-poll
-
-Arguments
-=========
-
-
-
-Description
-===========
-
-With the :ref:`poll() <func-poll>` function applications can suspend execution
-until the driver has captured data or is ready to accept data for
-output.
-
-When streaming I/O has been negotiated this function waits until a
-buffer has been filled by the capture device and can be dequeued with
-the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. For output devices this
-function waits until the device is ready to accept a new buffer to be
-queued up with the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl for
-display. When buffers are already in the outgoing queue of the driver
-(capture) or the incoming queue isn't full (display) the function
-returns immediately.
-
-On success :ref:`poll() <func-poll>` returns the number of file descriptors
-that have been selected (that is, file descriptors for which the
-``revents`` field of the respective :c:func:`struct pollfd` structure
-is non-zero). Capture devices set the ``POLLIN`` and ``POLLRDNORM``
-flags in the ``revents`` field, output devices the ``POLLOUT`` and
-``POLLWRNORM`` flags. When the function timed out it returns a value of
-zero, on failure it returns -1 and the ``errno`` variable is set
-appropriately. When the application did not call
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` the :ref:`poll() <func-poll>`
-function succeeds, but sets the ``POLLERR`` flag in the ``revents``
-field. When the application has called
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` for a capture device but
-hasn't yet called :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, the
-:ref:`poll() <func-poll>` function succeeds and sets the ``POLLERR`` flag in
-the ``revents`` field. For output devices this same situation will cause
-:ref:`poll() <func-poll>` to succeed as well, but it sets the ``POLLOUT`` and
-``POLLWRNORM`` flags in the ``revents`` field.
-
-If an event occurred (see :ref:`VIDIOC_DQEVENT`)
-then ``POLLPRI`` will be set in the ``revents`` field and
-:ref:`poll() <func-poll>` will return.
-
-When use of the :ref:`read() <func-read>` function has been negotiated and the
-driver does not capture yet, the :ref:`poll() <func-poll>` function starts
-capturing. When that fails it returns a ``POLLERR`` as above. Otherwise
-it waits until data has been captured and can be read. When the driver
-captures continuously (as opposed to, for example, still images) the
-function may return immediately.
-
-When use of the :ref:`write() <func-write>` function has been negotiated and the
-driver does not stream yet, the :ref:`poll() <func-poll>` function starts
-streaming. When that fails it returns a ``POLLERR`` as above. Otherwise
-it waits until the driver is ready for a non-blocking
-:ref:`write() <func-write>` call.
-
-If the caller is only interested in events (just ``POLLPRI`` is set in
-the ``events`` field), then :ref:`poll() <func-poll>` will *not* start
-streaming if the driver does not stream yet. This makes it possible to
-just poll for events and not for buffers.
-
-All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
-function or streaming I/O must also support the :ref:`poll() <func-poll>`
-function.
-
-For more details see the :ref:`poll() <func-poll>` manual page.
-
-
-Return Value
-============
-
-On success, :ref:`poll() <func-poll>` returns the number structures which have
-non-zero ``revents`` fields, or zero if the call timed out. On error -1
-is returned, and the ``errno`` variable is set appropriately:
-
-EBADF
-    One or more of the ``ufds`` members specify an invalid file
-    descriptor.
-
-EBUSY
-    The driver does not support multiple read or write streams and the
-    device is already in use.
-
-EFAULT
-    ``ufds`` references an inaccessible memory area.
-
-EINTR
-    The call was interrupted by a signal.
-
-EINVAL
-    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
-    ``getrlimit()`` to obtain this value.

-
-.. c:function:: ssize_t read( int fd, void *buf, size_t count )
-    :name: v4l2-read
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``buf``
-   Buffer to be filled
-
-``count``
-  Max number of bytes to read
-
-Description
-===========
-
-:ref:`read() <func-read>` attempts to read up to ``count`` bytes from file
-descriptor ``fd`` into the buffer starting at ``buf``. The layout of the
-data in the buffer is discussed in the respective device interface
-section, see ##. If ``count`` is zero, :ref:`read() <func-read>` returns zero
-and has no other results. If ``count`` is greater than ``SSIZE_MAX``,
-the result is unspecified. Regardless of the ``count`` value each
-:ref:`read() <func-read>` call will provide at most one frame (two fields)
-worth of data.
-
-By default :ref:`read() <func-read>` blocks until data becomes available. When
-the ``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>`
-function it returns immediately with an ``EAGAIN`` error code when no data
-is available. The :ref:`select() <func-select>` or
-:ref:`poll() <func-poll>` functions can always be used to suspend
-execution until data becomes available. All drivers supporting the
-:ref:`read() <func-read>` function must also support :ref:`select() <func-select>` and
-:ref:`poll() <func-poll>`.
-
-Drivers can implement read functionality in different ways, using a
-single or multiple buffers and discarding the oldest or newest frames
-once the internal buffers are filled.
-
-:ref:`read() <func-read>` never returns a "snapshot" of a buffer being filled.
-Using a single buffer the driver will stop capturing when the
-application starts reading the buffer until the read is finished. Thus
-only the period of the vertical blanking interval is available for
-reading, or the capture rate must fall below the nominal frame rate of
-the video standard.
-
-The behavior of :ref:`read() <func-read>` when called during the active picture
-period or the vertical blanking separating the top and bottom field
-depends on the discarding policy. A driver discarding the oldest frames
-keeps capturing into an internal buffer, continuously overwriting the
-previously, not read frame, and returns the frame being received at the
-time of the :ref:`read() <func-read>` call as soon as it is complete.
-
-A driver discarding the newest frames stops capturing until the next
-:ref:`read() <func-read>` call. The frame being received at :ref:`read() <func-read>`
-time is discarded, returning the following frame instead. Again this
-implies a reduction of the capture rate to one half or less of the
-nominal frame rate. An example of this model is the video read mode of
-the bttv driver, initiating a DMA to user memory when :ref:`read() <func-read>`
-is called and returning when the DMA finished.
-
-In the multiple buffer model drivers maintain a ring of internal
-buffers, automatically advancing to the next free buffer. This allows
-continuous capturing when the application can empty the buffers fast
-enough. Again, the behavior when the driver runs out of free buffers
-depends on the discarding policy.
-
-Applications can get and set the number of buffers used internally by
-the driver with the :ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
-:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctls. They are optional,
-however. The discarding policy is not reported and cannot be changed.
-For minimum requirements see :ref:`devices`.
-
-
-Return Value
-============
-
-On success, the number of bytes read is returned. It is not an error if
-this number is smaller than the number of bytes requested, or the amount
-of data required for one frame. This may happen for example because
-:ref:`read() <func-read>` was interrupted by a signal. On error, -1 is
-returned, and the ``errno`` variable is set appropriately. In this case
-the next read will start at the beginning of a new frame. Possible error
-codes are:
-
-EAGAIN
-    Non-blocking I/O has been selected using O_NONBLOCK and no data was
-    immediately available for reading.
-
-EBADF
-    ``fd`` is not a valid file descriptor or is not open for reading, or
-    the process already has the maximum number of files open.
-
-EBUSY
-    The driver does not support multiple read streams and the device is
-    already in use.
-
-EFAULT
-    ``buf`` references an inaccessible memory area.
-
-EINTR
-    The call was interrupted by a signal before any data was read.
-
-EIO
-    I/O error. This indicates some hardware problem or a failure to
-    communicate with a remote device (USB camera etc.).
-
-EINVAL
-    The :ref:`read() <func-read>` function is not supported by this driver, not
-    on this device, or generally not on this type of device.

-Synopsis
-========
-
-.. code-block:: c
-
-    #include <sys/time.h>
-    #include <sys/types.h>
-    #include <unistd.h>
-
-

-    :name: v4l2-select
-
-Arguments
-=========
-
-``nfds``
-  The highest-numbered file descriptor in any of the three sets, plus 1.
-
-``readfds``
-  File descriptions to be watched if a read() call won't block.
-
-``writefds``
-  File descriptions to be watched if a write() won't block.
-
-``exceptfds``
-  File descriptions to be watched for V4L2 events.
-
-``timeout``
-  Maximum time to wait.
-
-
-Description
-===========
-
-With the :ref:`select() <func-select>` function applications can suspend
-execution until the driver has captured data or is ready to accept data
-for output.
-
-When streaming I/O has been negotiated this function waits until a
-buffer has been filled or displayed and can be dequeued with the
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. When buffers are already in
-the outgoing queue of the driver the function returns immediately.
-
-On success :ref:`select() <func-select>` returns the total number of bits set in
-:c:func:`struct fd_set`. When the function timed out it returns
-a value of zero. On failure it returns -1 and the ``errno`` variable is
-set appropriately. When the application did not call
-:ref:`VIDIOC_QBUF` or
-:ref:`VIDIOC_STREAMON` yet the :ref:`select() <func-select>`
-function succeeds, setting the bit of the file descriptor in ``readfds``
-or ``writefds``, but subsequent :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
-calls will fail. [#f1]_
-
-When use of the :ref:`read() <func-read>` function has been negotiated and the
-driver does not capture yet, the :ref:`select() <func-select>` function starts
-capturing. When that fails, :ref:`select() <func-select>` returns successful and
-a subsequent :ref:`read() <func-read>` call, which also attempts to start
-capturing, will return an appropriate error code. When the driver
-captures continuously (as opposed to, for example, still images) and
-data is already available the :ref:`select() <func-select>` function returns
-immediately.
-
-When use of the :ref:`write() <func-write>` function has been negotiated the
-:ref:`select() <func-select>` function just waits until the driver is ready for a
-non-blocking :ref:`write() <func-write>` call.
-
-All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
-function or streaming I/O must also support the :ref:`select() <func-select>`
-function.
-
-For more details see the :ref:`select() <func-select>` manual page.
-
-
-Return Value
-============
-
-On success, :ref:`select() <func-select>` returns the number of descriptors
-contained in the three returned descriptor sets, which will be zero if
-the timeout expired. On error -1 is returned, and the ``errno`` variable
-is set appropriately; the sets and ``timeout`` are undefined. Possible
-error codes are:
-
-EBADF
-    One or more of the file descriptor sets specified a file descriptor
-    that is not open.
-
-EBUSY
-    The driver does not support multiple read or write streams and the
-    device is already in use.
-
-EFAULT
-    The ``readfds``, ``writefds``, ``exceptfds`` or ``timeout`` pointer
-    references an inaccessible memory area.
-
-EINTR
-    The call was interrupted by a signal.
-
-EINVAL
-    The ``nfds`` argument is less than zero or greater than
-    ``FD_SETSIZE``.
-
-.. [#f1]
-   The Linux kernel implements :ref:`select() <func-select>` like the
-   :ref:`poll() <func-poll>` function, but :ref:`select() <func-select>` cannot
-   return a ``POLLERR``.

-
-Description
-===========
-
-:ref:`write() <func-write>` writes up to ``count`` bytes to the device
-referenced by the file descriptor ``fd`` from the buffer starting at
-``buf``. When the hardware outputs are not active yet, this function
-enables them. When ``count`` is zero, :ref:`write() <func-write>` returns 0
-without any other effect.
-
-When the application does not provide more data in time, the previous
-video frame, raw VBI image, sliced VPS or WSS data is displayed again.
-Sliced Teletext or Closed Caption data is not repeated, the driver
-inserts a blank line instead.
-
-
-Return Value
-============
-
-On success, the number of bytes written are returned. Zero indicates
-nothing was written. On error, -1 is returned, and the ``errno``
-variable is set appropriately. In this case the next write will start at
-the beginning of a new frame. Possible error codes are:
-
-EAGAIN
-    Non-blocking I/O has been selected using the
-    :ref:`O_NONBLOCK <func-open>` flag and no buffer space was
-    available to write the data immediately.
-
-EBADF
-    ``fd`` is not a valid file descriptor or is not open for writing.
-
-EBUSY
-    The driver does not support multiple write streams and the device is
-    already in use.
-
-EFAULT
-    ``buf`` references an inaccessible memory area.
-
-EINTR
-    The call was interrupted by a signal before any data was written.

-EIO
-    I/O error. This indicates some hardware problem.
-
-EINVAL
-    The :ref:`write() <func-write>` function is not supported by this driver,
-    not on this device, or generally not on this type of device.

-***********************
-Changes of the V4L2 API
-***********************
-
-Soon after the V4L API was added to the kernel it was criticised as too
-inflexible. In August 1998 Bill Dirks proposed a number of improvements
-and began to work on documentation, example drivers and applications.
-With the help of other volunteers this eventually became the V4L2 API,
-not just an extension but a replacement for the V4L API. However it took
-another four years and two stable kernel releases until the new API was
-finally accepted for inclusion into the kernel in its present form.
-
-
-Early Versions
-==============
-
-1998-08-20: First version.
-
-1998-08-27: The :ref:`select() <func-select>` function was introduced.
-
-1998-09-10: New video standard interface.
-
-1998-09-18: The ``VIDIOC_NONCAP`` ioctl was replaced by the otherwise
-meaningless ``O_TRUNC`` :ref:`open() <func-open>` flag, and the
-aliases ``O_NONCAP`` and ``O_NOIO`` were defined. Applications can set
-this flag if they intend to access controls only, as opposed to capture
-applications which need exclusive access. The ``VIDEO_STD_XXX``
-identifiers are now ordinals instead of flags, and the
-``video_std_construct()`` helper function takes id and
-transmission arguments.
-
-1998-09-28: Revamped video standard. Made video controls individually
-enumerable.
-
-1998-10-02: The ``id`` field was removed from struct
-struct ``video_standard`` and the color subcarrier fields were
-renamed. The :ref:`VIDIOC_QUERYSTD` ioctl was
-renamed to :ref:`VIDIOC_ENUMSTD`,
-:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` to
-:ref:`VIDIOC_ENUMINPUT`. A first draft of the
-Codec API was released.
-
-1998-11-08: Many minor changes. Most symbols have been renamed. Some
-material changes to struct :c:type:`v4l2_capability`.
-
-1998-11-12: The read/write directon of some ioctls was misdefined.
-
-1998-11-14: ``V4L2_PIX_FMT_RGB24`` changed to ``V4L2_PIX_FMT_BGR24``,
-and ``V4L2_PIX_FMT_RGB32`` changed to ``V4L2_PIX_FMT_BGR32``. Audio
-controls are now accessible with the
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls under names starting
-with ``V4L2_CID_AUDIO``. The ``V4L2_MAJOR`` define was removed from
-``videodev.h`` since it was only used once in the ``videodev`` kernel
-module. The ``YUV422`` and ``YUV411`` planar image formats were added.
-
-1998-11-28: A few ioctl symbols changed. Interfaces for codecs and video
-output devices were added.
-
-1999-01-14: A raw VBI capture interface was added.
-
-1999-01-19: The ``VIDIOC_NEXTBUF`` ioctl was removed.
-
-
-V4L2 Version 0.16 1999-01-31
-============================
-
-1999-01-27: There is now one QBUF ioctl, VIDIOC_QWBUF and VIDIOC_QRBUF
-are gone. VIDIOC_QBUF takes a v4l2_buffer as a parameter. Added
-digital zoom (cropping) controls.
-
-
-V4L2 Version 0.18 1999-03-16
-============================
-
-Added a v4l to V4L2 ioctl compatibility layer to videodev.c. Driver
-writers, this changes how you implement your ioctl handler. See the
-Driver Writer's Guide. Added some more control id codes.
-
-
-V4L2 Version 0.19 1999-06-05
-============================
-
-1999-03-18: Fill in the category and catname fields of v4l2_queryctrl
-objects before passing them to the driver. Required a minor change to
-the VIDIOC_QUERYCTRL handlers in the sample drivers.
-
-1999-03-31: Better compatibility for v4l memory capture ioctls. Requires
-changes to drivers to fully support new compatibility features, see
-Driver Writer's Guide and v4l2cap.c. Added new control IDs:
-V4L2_CID_HFLIP, _VFLIP. Changed V4L2_PIX_FMT_YUV422P to _YUV422P,
-and _YUV411P to _YUV411P.
-
-1999-04-04: Added a few more control IDs.
-
-1999-04-07: Added the button control type.
-
-1999-05-02: Fixed a typo in videodev.h, and added the
-V4L2_CTRL_FLAG_GRAYED (later V4L2_CTRL_FLAG_GRABBED) flag.
-
-1999-05-20: Definition of VIDIOC_G_CTRL was wrong causing a
-malfunction of this ioctl.
-
-1999-06-05: Changed the value of V4L2_CID_WHITENESS.
-
-
-V4L2 Version 0.20 (1999-09-10)
-==============================
-
-Version 0.20 introduced a number of changes which were *not backward
-compatible* with 0.19 and earlier versions. Purpose of these changes was
-to simplify the API, while making it more extensible and following
-common Linux driver API conventions.
-
-1. Some typos in ``V4L2_FMT_FLAG`` symbols were fixed. struct
-   :c:type:`v4l2_clip` was changed for compatibility with
-   v4l. (1999-08-30)
-
-2. ``V4L2_TUNER_SUB_LANG1`` was added. (1999-09-05)
-
-3. All ioctl() commands that used an integer argument now take a pointer
-   to an integer. Where it makes sense, ioctls will return the actual
-   new value in the integer pointed to by the argument, a common
-   convention in the V4L2 API. The affected ioctls are: VIDIOC_PREVIEW,
-   VIDIOC_STREAMON, VIDIOC_STREAMOFF, VIDIOC_S_FREQ,
-   VIDIOC_S_INPUT, VIDIOC_S_OUTPUT, VIDIOC_S_EFFECT. For example
-
-
-   .. code-block:: c
-
-       err = ioctl (fd, VIDIOC_XXX, V4L2_XXX);
-
-   becomes
-
-
-   .. code-block:: c
-
-       int a = V4L2_XXX; err = ioctl(fd, VIDIOC_XXX, &a);
-
-4. All the different get- and set-format commands were swept into one
-   :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-   :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl taking a union and a
-   type field selecting the union member as parameter. Purpose is to
-   simplify the API by eliminating several ioctls and to allow new and
-   driver private data streams without adding new ioctls.
-
-   This change obsoletes the following ioctls: ``VIDIOC_S_INFMT``,
-   ``VIDIOC_G_INFMT``, ``VIDIOC_S_OUTFMT``, ``VIDIOC_G_OUTFMT``,
-   ``VIDIOC_S_VBIFMT`` and ``VIDIOC_G_VBIFMT``. The image format
-   structure struct :c:type:`v4l2_format` was renamed to struct
-   :c:type:`v4l2_pix_format`, while struct
-   :c:type:`v4l2_format` is now the envelopping structure
-   for all format negotiations.
-
-5. Similar to the changes above, the ``VIDIOC_G_PARM`` and
-   ``VIDIOC_S_PARM`` ioctls were merged with ``VIDIOC_G_OUTPARM`` and
-   ``VIDIOC_S_OUTPARM``. A ``type`` field in the new struct
-   :c:type:`v4l2_streamparm` selects the respective
-   union member.
-
-   This change obsoletes the ``VIDIOC_G_OUTPARM`` and
-   ``VIDIOC_S_OUTPARM`` ioctls.
-
-6. Control enumeration was simplified, and two new control flags were
-   introduced and one dropped. The ``catname`` field was replaced by a
-   ``group`` field.
-
-   Drivers can now flag unsupported and temporarily unavailable controls
-   with ``V4L2_CTRL_FLAG_DISABLED`` and ``V4L2_CTRL_FLAG_GRABBED``
-   respectively. The ``group`` name indicates a possibly narrower
-   classification than the ``category``. In other words, there may be
-   multiple groups within a category. Controls within a group would
-   typically be drawn within a group box. Controls in different
-   categories might have a greater separation, or may even appear in
-   separate windows.
-
-7. The struct :c:type:`v4l2_buffer` ``timestamp`` was
-   changed to a 64 bit integer, containing the sampling or output time
-   of the frame in nanoseconds. Additionally timestamps will be in
-   absolute system time, not starting from zero at the beginning of a
-   stream. The data type name for timestamps is stamp_t, defined as a
-   signed 64-bit integer. Output devices should not send a buffer out
-   until the time in the timestamp field has arrived. I would like to
-   follow SGI's lead, and adopt a multimedia timestamping system like
-   their UST (Unadjusted System Time). See
-   http://web.archive.org/web/\*/http://reality.sgi.com
-   /cpirazzi_engr/lg/time/intro.html. UST uses timestamps that are
-   64-bit signed integers (not struct timeval's) and given in nanosecond
-   units. The UST clock starts at zero when the system is booted and
-   runs continuously and uniformly. It takes a little over 292 years for
-   UST to overflow. There is no way to set the UST clock. The regular
-   Linux time-of-day clock can be changed periodically, which would
-   cause errors if it were being used for timestamping a multimedia
-   stream. A real UST style clock will require some support in the
-   kernel that is not there yet. But in anticipation, I will change the
-   timestamp field to a 64-bit integer, and I will change the
-   v4l2_masterclock_gettime() function (used only by drivers) to
-   return a 64-bit integer.
-
-8. A ``sequence`` field was added to struct
-   :c:type:`v4l2_buffer`. The ``sequence`` field counts
-   captured frames, it is ignored by output devices. When a capture
-   driver drops a frame, the sequence number of that frame is skipped.
-
-
-V4L2 Version 0.20 incremental changes
-=====================================
-
-1999-12-23: In struct :c:type:`v4l2_vbi_format` the
-``reserved1`` field became ``offset``. Previously drivers were required
-to clear the ``reserved1`` field.
-
-2000-01-13: The ``V4L2_FMT_FLAG_NOT_INTERLACED`` flag was added.
-
-2000-07-31: The ``linux/poll.h`` header is now included by
-``videodev.h`` for compatibility with the original ``videodev.h`` file.
-
-2000-11-20: ``V4L2_TYPE_VBI_OUTPUT`` and ``V4L2_PIX_FMT_Y41P`` were
-added.
-
-2000-11-25: ``V4L2_TYPE_VBI_INPUT`` was added.
-
-2000-12-04: A couple typos in symbol names were fixed.
-
-2001-01-18: To avoid namespace conflicts the ``fourcc`` macro defined in
-the ``videodev.h`` header file was renamed to ``v4l2_fourcc``.
-
-2001-01-25: A possible driver-level compatibility problem between the
-``videodev.h`` file in Linux 2.4.0 and the ``videodev.h`` file included
-in the ``videodevX`` patch was fixed. Users of an earlier version of
-``videodevX`` on Linux 2.4.0 should recompile their V4L and V4L2
-drivers.
-
-2001-01-26: A possible kernel-level incompatibility between the
-``videodev.h`` file in the ``videodevX`` patch and the ``videodev.h``
-file in Linux 2.2.x with devfs patches applied was fixed.
-
-2001-03-02: Certain V4L ioctls which pass data in both direction
-although they are defined with read-only parameter, did not work
-correctly through the backward compatibility layer. [Solution?]
-
-2001-04-13: Big endian 16-bit RGB formats were added.
-
-2001-09-17: New YUV formats and the
-:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctls were added.
-(The old ``VIDIOC_G_FREQ`` and ``VIDIOC_S_FREQ`` ioctls did not take
-multiple tuners into account.)
-
-2000-09-18: ``V4L2_BUF_TYPE_VBI`` was added. This may *break
-compatibility* as the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls may fail now if the struct
-struct ``v4l2_fmt`` ``type`` field does not contain
-``V4L2_BUF_TYPE_VBI``. In the documentation of the struct
-:c:type:`v4l2_vbi_format` ``offset`` field the
-ambiguous phrase "rising edge" was changed to "leading edge".
-
-
-V4L2 Version 0.20 2000-11-23
-============================
-
-A number of changes were made to the raw VBI interface.
-
-1. Figures clarifying the line numbering scheme were added to the V4L2
-   API specification. The ``start``\ [0] and ``start``\ [1] fields no
-   longer count line numbers beginning at zero. Rationale: a) The
-   previous definition was unclear. b) The ``start``\ [] values are
-   ordinal numbers. c) There is no point in inventing a new line
-   numbering scheme. We now use line number as defined by ITU-R, period.
-   Compatibility: Add one to the start values. Applications depending on
-   the previous semantics may not function correctly.
-
-2. The restriction "count[0] > 0 and count[1] > 0" has been relaxed to
-   "(count[0] + count[1]) > 0". Rationale: Drivers may allocate
-   resources at scan line granularity and some data services are
-   transmitted only on the first field. The comment that both ``count``
-   values will usually be equal is misleading and pointless and has been
-   removed. This change *breaks compatibility* with earlier versions:
-   Drivers may return ``EINVAL``, applications may not function correctly.
-
-3. Drivers are again permitted to return negative (unknown) start values
-   as proposed earlier. Why this feature was dropped is unclear. This
-   change may *break compatibility* with applications depending on the
-   start values being positive. The use of ``EBUSY`` and ``EINVAL``
-   error codes with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl was
-   clarified. The ``EBUSY`` error code was finally documented, and the
-   ``reserved2`` field which was previously mentioned only in the
-   ``videodev.h`` header file.
-
-4. New buffer types ``V4L2_TYPE_VBI_INPUT`` and ``V4L2_TYPE_VBI_OUTPUT``
-   were added. The former is an alias for the old ``V4L2_TYPE_VBI``, the
-   latter was missing in the ``videodev.h`` file.
-
-
-V4L2 Version 0.20 2002-07-25
-============================
-
-Added sliced VBI interface proposal.
-
-
-V4L2 in Linux 2.5.46, 2002-10
-=============================
-
-Around October-November 2002, prior to an announced feature freeze of
-Linux 2.5, the API was revised, drawing from experience with V4L2 0.20.
-This unnamed version was finally merged into Linux 2.5.46.
-
-1.  As specified in :ref:`related`, drivers must make related device
-    functions available under all minor device numbers.
-
-2.  The :ref:`open() <func-open>` function requires access mode
-    ``O_RDWR`` regardless of the device type. All V4L2 drivers
-    exchanging data with applications must support the ``O_NONBLOCK``
-    flag. The ``O_NOIO`` flag, a V4L2 symbol which aliased the
-    meaningless ``O_TRUNC`` to indicate accesses without data exchange
-    (panel applications) was dropped. Drivers must stay in "panel mode"
-    until the application attempts to initiate a data exchange, see
-    :ref:`open`.
-
-3.  The struct :c:type:`v4l2_capability` changed
-    dramatically. Note that also the size of the structure changed,
-    which is encoded in the ioctl request code, thus older V4L2 devices
-    will respond with an ``EINVAL`` error code to the new
-    :ref:`VIDIOC_QUERYCAP` ioctl.
-
-    There are new fields to identify the driver, a new RDS device
-    function ``V4L2_CAP_RDS_CAPTURE``, the ``V4L2_CAP_AUDIO`` flag
-    indicates if the device has any audio connectors, another I/O
-    capability ``V4L2_CAP_ASYNCIO`` can be flagged. In response to these
-    changes the ``type`` field became a bit set and was merged into the
-    ``flags`` field. ``V4L2_FLAG_TUNER`` was renamed to
-    ``V4L2_CAP_TUNER``, ``V4L2_CAP_VIDEO_OVERLAY`` replaced
-    ``V4L2_FLAG_PREVIEW`` and ``V4L2_CAP_VBI_CAPTURE`` and
-    ``V4L2_CAP_VBI_OUTPUT`` replaced ``V4L2_FLAG_DATA_SERVICE``.
-    ``V4L2_FLAG_READ`` and ``V4L2_FLAG_WRITE`` were merged into
-    ``V4L2_CAP_READWRITE``.
-
-    The redundant fields ``inputs``, ``outputs`` and ``audios`` were
-    removed. These properties can be determined as described in
-    :ref:`video` and :ref:`audio`.
-
-    The somewhat volatile and therefore barely useful fields
-    ``maxwidth``, ``maxheight``, ``minwidth``, ``minheight``,
-    ``maxframerate`` were removed. This information is available as
-    described in :ref:`format` and :ref:`standard`.
-
-    ``V4L2_FLAG_SELECT`` was removed. We believe the select() function
-    is important enough to require support of it in all V4L2 drivers
-    exchanging data with applications. The redundant
-    ``V4L2_FLAG_MONOCHROME`` flag was removed, this information is
-    available as described in :ref:`format`.
-
-4.  In struct :c:type:`v4l2_input` the ``assoc_audio``
-    field and the ``capability`` field and its only flag
-    ``V4L2_INPUT_CAP_AUDIO`` was replaced by the new ``audioset`` field.
-    Instead of linking one video input to one audio input this field
-    reports all audio inputs this video input combines with.
-
-    New fields are ``tuner`` (reversing the former link from tuners to
-    video inputs), ``std`` and ``status``.
-
-    Accordingly struct :c:type:`v4l2_output` lost its
-    ``capability`` and ``assoc_audio`` fields. ``audioset``,
-    ``modulator`` and ``std`` where added instead.
-
-5.  The struct :c:type:`v4l2_audio` field ``audio`` was
-    renamed to ``index``, for consistency with other structures. A new
-    capability flag ``V4L2_AUDCAP_STEREO`` was added to indicated if the
-    audio input in question supports stereo sound.
-    ``V4L2_AUDCAP_EFFECTS`` and the corresponding ``V4L2_AUDMODE`` flags
-    where removed. This can be easily implemented using controls.
-    (However the same applies to AVL which is still there.)
-
-    Again for consistency the struct
-    :c:type:`v4l2_audioout` field ``audio`` was renamed
-    to ``index``.
-
-6.  The struct :c:type:`v4l2_tuner` ``input`` field was
-    replaced by an ``index`` field, permitting devices with multiple
-    tuners. The link between video inputs and tuners is now reversed,
-    inputs point to their tuner. The ``std`` substructure became a
-    simple set (more about this below) and moved into struct
-    :c:type:`v4l2_input`. A ``type`` field was added.
-
-    Accordingly in struct :c:type:`v4l2_modulator` the
-    ``output`` was replaced by an ``index`` field.
-
-    In struct :c:type:`v4l2_frequency` the ``port``
-    field was replaced by a ``tuner`` field containing the respective
-    tuner or modulator index number. A tuner ``type`` field was added
-    and the ``reserved`` field became larger for future extensions
-    (satellite tuners in particular).
-
-7.  The idea of completely transparent video standards was dropped.
-    Experience showed that applications must be able to work with video
-    standards beyond presenting the user a menu. Instead of enumerating
-    supported standards with an ioctl applications can now refer to
-    standards by :ref:`v4l2_std_id <v4l2-std-id>` and symbols
-    defined in the ``videodev2.h`` header file. For details see
-    :ref:`standard`. The :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
-    :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` now take a pointer to this
-    type as argument. :ref:`VIDIOC_QUERYSTD` was
-    added to autodetect the received standard, if the hardware has this
-    capability. In struct :c:type:`v4l2_standard` an
-    ``index`` field was added for
-    :ref:`VIDIOC_ENUMSTD`. A
-    :ref:`v4l2_std_id <v4l2-std-id>` field named ``id`` was added as
-    machine readable identifier, also replacing the ``transmission``
-    field. The misleading ``framerate`` field was renamed to
-    ``frameperiod``. The now obsolete ``colorstandard`` information,
-    originally needed to distguish between variations of standards, were
-    removed.
-
-    Struct ``v4l2_enumstd`` ceased to be.
-    :ref:`VIDIOC_ENUMSTD` now takes a pointer to a
-    struct :c:type:`v4l2_standard` directly. The
-    information which standards are supported by a particular video
-    input or output moved into struct :c:type:`v4l2_input`
-    and struct :c:type:`v4l2_output` fields named ``std``,
-    respectively.
-
-8.  The struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` fields
-    ``category`` and ``group`` did not catch on and/or were not
-    implemented as expected and therefore removed.
-
-9.  The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl was added to
-    negotiate data formats as with
-    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, but without the overhead of
-    programming the hardware and regardless of I/O in progress.
-
-    In struct :c:type:`v4l2_format` the ``fmt`` union was
-    extended to contain struct :c:type:`v4l2_window`. All
-    image format negotiations are now possible with ``VIDIOC_G_FMT``,
-    ``VIDIOC_S_FMT`` and ``VIDIOC_TRY_FMT``; ioctl. The ``VIDIOC_G_WIN``
-    and ``VIDIOC_S_WIN`` ioctls to prepare for a video overlay were
-    removed. The ``type`` field changed to type enum
-    :c:type:`v4l2_buf_type` and the buffer type names
-    changed as follows.
-
-
-
-    .. flat-table::
-	:header-rows:  1
-	:stub-columns: 0
-
-	* - Old defines
-	  - enum :c:type:`v4l2_buf_type`

-	  - ``V4L2_BUF_TYPE_PRIVATE`` (but this is deprecated)
-
-
-10. In struct :c:type:`v4l2_fmtdesc` a enum
-    :c:type:`v4l2_buf_type` field named ``type`` was
-    added as in struct :c:type:`v4l2_format`. The
-    ``VIDIOC_ENUM_FBUFFMT`` ioctl is no longer needed and was removed.
-    These calls can be replaced by
-    :ref:`VIDIOC_ENUM_FMT` with type
-    ``V4L2_BUF_TYPE_VIDEO_OVERLAY``.
-
-11. In struct :c:type:`v4l2_pix_format` the ``depth``
-    field was removed, assuming applications which recognize the format
-    by its four-character-code already know the color depth, and others
-    do not care about it. The same rationale lead to the removal of the
-    ``V4L2_FMT_FLAG_COMPRESSED`` flag. The
-    ``V4L2_FMT_FLAG_SWCONVECOMPRESSED`` flag was removed because drivers
-    are not supposed to convert images in kernel space. A user library
-    of conversion functions should be provided instead. The
-    ``V4L2_FMT_FLAG_BYTESPERLINE`` flag was redundant. Applications can
-    set the ``bytesperline`` field to zero to get a reasonable default.
-    Since the remaining flags were replaced as well, the ``flags`` field
-    itself was removed.
-
-    The interlace flags were replaced by a enum
-    :c:type:`v4l2_field` value in a newly added ``field``
-    field.
-
-
-
-    .. flat-table::
-	:header-rows:  1
-	:stub-columns: 0
-
-	* - Old flag
-	  - enum :c:type:`v4l2_field`
-	* - ``V4L2_FMT_FLAG_NOT_INTERLACED``
-	  - ?

-	  - ``V4L2_FIELD_INTERLACED``
-	* - ``V4L2_FMT_FLAG_TOPFIELD`` = ``V4L2_FMT_FLAG_ODDFIELD``
-	  - ``V4L2_FIELD_TOP``

-	* - ``-``
-	  - ``V4L2_FIELD_SEQ_BT``
-	* - ``-``
-	  - ``V4L2_FIELD_ALTERNATE``
-
-
-    The color space flags were replaced by a enum
-    :c:type:`v4l2_colorspace` value in a newly added
-    ``colorspace`` field, where one of ``V4L2_COLORSPACE_SMPTE170M``,
-    ``V4L2_COLORSPACE_BT878``, ``V4L2_COLORSPACE_470_SYSTEM_M`` or
-    ``V4L2_COLORSPACE_470_SYSTEM_BG`` replaces ``V4L2_FMT_CS_601YUV``.
-
-12. In struct :c:type:`v4l2_requestbuffers` the
-    ``type`` field was properly defined as enum
-    :c:type:`v4l2_buf_type`. Buffer types changed as
-    mentioned above. A new ``memory`` field of type enum
-    :c:type:`v4l2_memory` was added to distinguish between
-    I/O methods using buffers allocated by the driver or the
-    application. See :ref:`io` for details.
-
-13. In struct :c:type:`v4l2_buffer` the ``type`` field was
-    properly defined as enum :c:type:`v4l2_buf_type`.
-    Buffer types changed as mentioned above. A ``field`` field of type
-    enum :c:type:`v4l2_field` was added to indicate if a
-    buffer contains a top or bottom field. The old field flags were
-    removed. Since no unadjusted system time clock was added to the
-    kernel as planned, the ``timestamp`` field changed back from type
-    stamp_t, an unsigned 64 bit integer expressing the sample time in
-    nanoseconds, to struct :c:type:`timeval`. With the addition
-    of a second memory mapping method the ``offset`` field moved into
-    union ``m``, and a new ``memory`` field of type enum
-    :c:type:`v4l2_memory` was added to distinguish between
-    I/O methods. See :ref:`io` for details.
-
-    The ``V4L2_BUF_REQ_CONTIG`` flag was used by the V4L compatibility
-    layer, after changes to this code it was no longer needed. The
-    ``V4L2_BUF_ATTR_DEVICEMEM`` flag would indicate if the buffer was
-    indeed allocated in device memory rather than DMA-able system
-    memory. It was barely useful and so was removed.
-
-14. In struct :c:type:`v4l2_framebuffer` the
-    ``base[3]`` array anticipating double- and triple-buffering in
-    off-screen video memory, however without defining a synchronization
-    mechanism, was replaced by a single pointer. The
-    ``V4L2_FBUF_CAP_SCALEUP`` and ``V4L2_FBUF_CAP_SCALEDOWN`` flags were
-    removed. Applications can determine this capability more accurately
-    using the new cropping and scaling interface. The
-    ``V4L2_FBUF_CAP_CLIPPING`` flag was replaced by
-    ``V4L2_FBUF_CAP_LIST_CLIPPING`` and
-    ``V4L2_FBUF_CAP_BITMAP_CLIPPING``.
-
-15. In struct :c:type:`v4l2_clip` the ``x``, ``y``,
-    ``width`` and ``height`` field moved into a ``c`` substructure of
-    type struct :c:type:`v4l2_rect`. The ``x`` and ``y``
-    fields were renamed to ``left`` and ``top``, i. e. offsets to a
-    context dependent origin.
-
-16. In struct :c:type:`v4l2_window` the ``x``, ``y``,
-    ``width`` and ``height`` field moved into a ``w`` substructure as
-    above. A ``field`` field of type :c:type:`v4l2_field` was added to
-    distinguish between field and frame (interlaced) overlay.
-
-17. The digital zoom interface, including struct
-    struct ``v4l2_zoomcap``, struct
-    struct ``v4l2_zoom``, ``V4L2_ZOOM_NONCAP`` and
-    ``V4L2_ZOOM_WHILESTREAMING`` was replaced by a new cropping and
-    scaling interface. The previously unused struct
-    struct :c:type:`v4l2_cropcap` and struct :c:type:`v4l2_crop`
-    where redefined for this purpose. See :ref:`crop` for details.
-
-18. In struct :c:type:`v4l2_vbi_format` the
-    ``SAMPLE_FORMAT`` field now contains a four-character-code as used
-    to identify video image formats and ``V4L2_PIX_FMT_GREY`` replaces
-    the ``V4L2_VBI_SF_UBYTE`` define. The ``reserved`` field was
-    extended.
-
-19. In struct :c:type:`v4l2_captureparm` the type of
-    the ``timeperframe`` field changed from unsigned long to struct
-    :c:type:`v4l2_fract`. This allows the accurate
-    expression of multiples of the NTSC-M frame rate 30000 / 1001. A new
-    field ``readbuffers`` was added to control the driver behaviour in
-    read I/O mode.
-
-    Similar changes were made to struct
-    :c:type:`v4l2_outputparm`.
-
-20. The struct ``v4l2_performance`` and
-    ``VIDIOC_G_PERF`` ioctl were dropped. Except when using the
-    :ref:`read/write I/O method <rw>`, which is limited anyway, this
-    information is already available to applications.
-
-21. The example transformation from RGB to YCbCr color space in the old
-    V4L2 documentation was inaccurate, this has been corrected in
-    :ref:`pixfmt`.
-
-
-V4L2 2003-06-19
-===============
-
-1. A new capability flag ``V4L2_CAP_RADIO`` was added for radio devices.
-   Prior to this change radio devices would identify solely by having
-   exactly one tuner whose type field reads ``V4L2_TUNER_RADIO``.
-
-2. An optional driver access priority mechanism was added, see
-   :ref:`app-pri` for details.
-
-3. The audio input and output interface was found to be incomplete.
-
-   Previously the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl would
-   enumerate the available audio inputs. An ioctl to determine the
-   current audio input, if more than one combines with the current video
-   input, did not exist. So ``VIDIOC_G_AUDIO`` was renamed to
-   ``VIDIOC_G_AUDIO_OLD``, this ioctl was removed on Kernel 2.6.39. The
-   :ref:`VIDIOC_ENUMAUDIO` ioctl was added to
-   enumerate audio inputs, while
-   :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` now reports the current
-   audio input.
-
-   The same changes were made to
-   :ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` and
-   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>`.
-
-   Until further the "videodev" module will automatically translate
-   between the old and new ioctls, but drivers and applications must be
-   updated to successfully compile again.
-
-4. The :ref:`VIDIOC_OVERLAY` ioctl was incorrectly
-   defined with write-read parameter. It was changed to write-only,
-   while the write-read version was renamed to ``VIDIOC_OVERLAY_OLD``.
-   The old ioctl was removed on Kernel 2.6.39. Until further the
-   "videodev" kernel module will automatically translate to the new
-   version, so drivers must be recompiled, but not applications.
-
-5. :ref:`overlay` incorrectly stated that clipping rectangles define
-   regions where the video can be seen. Correct is that clipping
-   rectangles define regions where *no* video shall be displayed and so
-   the graphics surface can be seen.
-
-6. The :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` and
-   :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls were defined with
-   write-only parameter, inconsistent with other ioctls modifying their
-   argument. They were changed to write-read, while a ``_OLD`` suffix
-   was added to the write-only versions. The old ioctls were removed on
-   Kernel 2.6.39. Drivers and applications assuming a constant parameter
-   need an update.
-
-
-V4L2 2003-11-05
-===============
-
-1. In :ref:`pixfmt-rgb` the following pixel formats were incorrectly
-   transferred from Bill Dirks' V4L2 specification. Descriptions below
-   refer to bytes in memory, in ascending address order.
-

-   The ``V4L2_PIX_FMT_BGR24`` example was always correct.
-
-   In :ref:`v4l-image-properties` the mapping of the V4L
-   ``VIDEO_PALETTE_RGB24`` and ``VIDEO_PALETTE_RGB32`` formats to V4L2
-   pixel formats was accordingly corrected.
-
-2. Unrelated to the fixes above, drivers may still interpret some V4L2
-   RGB pixel formats differently. These issues have yet to be addressed,
-   for details see :ref:`pixfmt-rgb`.
-
-
-V4L2 in Linux 2.6.6, 2004-05-09
-===============================
-
-1. The :ref:`VIDIOC_CROPCAP` ioctl was incorrectly
-   defined with read-only parameter. It is now defined as write-read
-   ioctl, while the read-only version was renamed to
-   ``VIDIOC_CROPCAP_OLD``. The old ioctl was removed on Kernel 2.6.39.
-
-
-V4L2 in Linux 2.6.8
-===================
-
-1. A new field ``input`` (former ``reserved[0]``) was added to the
-   struct :c:type:`v4l2_buffer` structure. Purpose of this
-   field is to alternate between video inputs (e. g. cameras) in step
-   with the video capturing process. This function must be enabled with
-   the new ``V4L2_BUF_FLAG_INPUT`` flag. The ``flags`` field is no
-   longer read-only.
-
-
-V4L2 spec erratum 2004-08-01
-============================
-
-1. The return value of the :ref:`func-open` function was incorrectly
-   documented.
-
-2. Audio output ioctls end in -AUDOUT, not -AUDIOOUT.
-
-3. In the Current Audio Input example the ``VIDIOC_G_AUDIO`` ioctl took
-   the wrong argument.
-
-4. The documentation of the :ref:`VIDIOC_QBUF` and
-   :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctls did not mention the
-   struct :c:type:`v4l2_buffer` ``memory`` field. It was
-   also missing from examples. Also on the ``VIDIOC_DQBUF`` page the ``EIO``
-   error code was not documented.
-
-
-V4L2 in Linux 2.6.14
-====================
-
-1. A new sliced VBI interface was added. It is documented in
-   :ref:`sliced` and replaces the interface first proposed in V4L2
-   specification 0.8.
-
-
-V4L2 in Linux 2.6.15
-====================
-
-1. The :ref:`VIDIOC_LOG_STATUS` ioctl was added.
-
-2. New video standards ``V4L2_STD_NTSC_443``, ``V4L2_STD_SECAM_LC``,
-   ``V4L2_STD_SECAM_DK`` (a set of SECAM D, K and K1), and
-   ``V4L2_STD_ATSC`` (a set of ``V4L2_STD_ATSC_8_VSB`` and
-   ``V4L2_STD_ATSC_16_VSB``) were defined. Note the ``V4L2_STD_525_60``
-   set now includes ``V4L2_STD_NTSC_443``. See also
-   :ref:`v4l2-std-id`.
-
-3. The ``VIDIOC_G_COMP`` and ``VIDIOC_S_COMP`` ioctl were renamed to
-   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` respectively. Their
-   argument was replaced by a struct
-   ``v4l2_mpeg_compression`` pointer. (The
-   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls where removed
-   in Linux 2.6.25.)
-
-
-V4L2 spec erratum 2005-11-27
-============================
-
-The capture example in :ref:`capture-example` called the
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl without checking if
-cropping is supported. In the video standard selection example in
-:ref:`standard` the :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` call used
-the wrong argument type.
-
-
-V4L2 spec erratum 2006-01-10
-============================
-
-1. The ``V4L2_IN_ST_COLOR_KILL`` flag in struct
-   :c:type:`v4l2_input` not only indicates if the color
-   killer is enabled, but also if it is active. (The color killer
-   disables color decoding when it detects no color in the video signal
-   to improve the image quality.)
-
-2. :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` is a write-read ioctl, not
-   write-only as stated on its reference page. The ioctl changed in 2003
-   as noted above.
-
-
-V4L2 spec erratum 2006-02-03
-============================
-
-1. In struct :c:type:`v4l2_captureparm` and struct
-   :c:type:`v4l2_outputparm` the ``timeperframe``
-   field gives the time in seconds, not microseconds.
-
-
-V4L2 spec erratum 2006-02-04
-============================
-
-1. The ``clips`` field in struct :c:type:`v4l2_window`
-   must point to an array of struct :c:type:`v4l2_clip`, not
-   a linked list, because drivers ignore the struct
-   struct :c:type:`v4l2_clip`. ``next`` pointer.
-
-
-V4L2 in Linux 2.6.17
-====================
-
-1. New video standard macros were added: ``V4L2_STD_NTSC_M_KR`` (NTSC M
-   South Korea), and the sets ``V4L2_STD_MN``, ``V4L2_STD_B``,
-   ``V4L2_STD_GH`` and ``V4L2_STD_DK``. The ``V4L2_STD_NTSC`` and
-   ``V4L2_STD_SECAM`` sets now include ``V4L2_STD_NTSC_M_KR`` and
-   ``V4L2_STD_SECAM_LC`` respectively.
-
-2. A new ``V4L2_TUNER_MODE_LANG1_LANG2`` was defined to record both
-   languages of a bilingual program. The use of
-   ``V4L2_TUNER_MODE_STEREO`` for this purpose is deprecated now. See
-   the :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` section for details.
-
-
-V4L2 spec erratum 2006-09-23 (Draft 0.15)
-=========================================
-
-1. In various places ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` and
-   ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT`` of the sliced VBI interface were
-   not mentioned along with other buffer types.
-
-2. In :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` it was clarified that the struct
-   :c:type:`v4l2_audio` ``mode`` field is a flags field.
-
-3. :ref:`VIDIOC_QUERYCAP` did not mention the sliced VBI and radio
-   capability flags.
-
-4. In :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` it was clarified that applications
-   must initialize the tuner ``type`` field of struct
-   :c:type:`v4l2_frequency` before calling
-   :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`.
-
-5. The ``reserved`` array in struct
-   :c:type:`v4l2_requestbuffers` has 2 elements,
-   not 32.
-
-6. In :ref:`output` and :ref:`raw-vbi` the device file names
-   ``/dev/vout`` which never caught on were replaced by ``/dev/video``.
-
-7. With Linux 2.6.15 the possible range for VBI device minor numbers was
-   extended from 224-239 to 224-255. Accordingly device file names
-   ``/dev/vbi0`` to ``/dev/vbi31`` are possible now.
-
-
-V4L2 in Linux 2.6.18
-====================
-
-1. New ioctls :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-   :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
-   :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` were added, a
-   flag to skip unsupported controls with
-   :ref:`VIDIOC_QUERYCTRL`, new control types
-   ``V4L2_CTRL_TYPE_INTEGER64`` and ``V4L2_CTRL_TYPE_CTRL_CLASS``
-   (:c:type:`v4l2_ctrl_type`), and new control flags
-   ``V4L2_CTRL_FLAG_READ_ONLY``, ``V4L2_CTRL_FLAG_UPDATE``,
-   ``V4L2_CTRL_FLAG_INACTIVE`` and ``V4L2_CTRL_FLAG_SLIDER``
-   (:ref:`control-flags`). See :ref:`extended-controls` for details.
-
-
-V4L2 in Linux 2.6.19
-====================
-
-1. In struct :c:type:`v4l2_sliced_vbi_cap` a
-   buffer type field was added replacing a reserved field. Note on
-   architectures where the size of enum types differs from int types the
-   size of the structure changed. The
-   :ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl
-   was redefined from being read-only to write-read. Applications must
-   initialize the type field and clear the reserved fields now. These
-   changes may *break the compatibility* with older drivers and
-   applications.
-
-2. The ioctls :ref:`VIDIOC_ENUM_FRAMESIZES`
-   and
-   :ref:`VIDIOC_ENUM_FRAMEINTERVALS`
-   were added.
-
-3. A new pixel format ``V4L2_PIX_FMT_RGB444`` (:ref:`pixfmt-rgb`) was
-   added.

-   4:2:2 format.
-
-
-V4L2 in Linux 2.6.21
-====================
-
-1. The ``videodev2.h`` header file is now dual licensed under GNU

-   BSD-style license.
-
-
-V4L2 in Linux 2.6.22
-====================
-
-1. Two new field orders ``V4L2_FIELD_INTERLACED_TB`` and

-   details.
-
-2. Three new clipping/blending methods with a global or straight or
-   inverted local alpha value were added to the video overlay interface.
-   See the description of the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-   and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls for details.
-
-   A new ``global_alpha`` field was added to
-   :c:type:`v4l2_window`, extending the structure. This
-   may *break compatibility* with applications using a struct
-   struct :c:type:`v4l2_window` directly. However the
-   :ref:`VIDIOC_G/S/TRY_FMT <VIDIOC_G_FMT>` ioctls, which take a
-   pointer to a :c:type:`v4l2_format` parent structure
-   with padding bytes at the end, are not affected.
-
-3. The format of the ``chromakey`` field in struct
-   :c:type:`v4l2_window` changed from "host order RGB32"
-   to a pixel value in the same format as the framebuffer. This may
-   *break compatibility* with existing applications. Drivers supporting
-   the "host order RGB32" format are not known.
-

-
-Relation of V4L2 to other Linux multimedia APIs
-===============================================
-
-
-.. _xvideo:
-
-X Video Extension
------------------
-
-The X Video Extension (abbreviated XVideo or just Xv) is an extension of
-the X Window system, implemented for example by the XFree86 project. Its
-scope is similar to V4L2, an API to video capture and output devices for
-X clients. Xv allows applications to display live video in a window,
-send window contents to a TV output, and capture or output still images
-in XPixmaps [#f1]_. With their implementation XFree86 makes the extension
-available across many operating systems and architectures.
-
-Because the driver is embedded into the X server Xv has a number of
-advantages over the V4L2 :ref:`video overlay interface <overlay>`. The
-driver can easily determine the overlay target, i. e. visible graphics
-memory or off-screen buffers for a destructive overlay. It can program
-the RAMDAC for a non-destructive overlay, scaling or color-keying, or
-the clipping functions of the video capture hardware, always in sync
-with drawing operations or windows moving or changing their stacking
-order.
-
-To combine the advantages of Xv and V4L a special Xv driver exists in
-XFree86 and XOrg, just programming any overlay capable Video4Linux
-device it finds. To enable it ``/etc/X11/XF86Config`` must contain these
-lines:
-
-::
-
-    Section "Module"
-	Load "v4l"
-    EndSection
-
-As of XFree86 4.2 this driver still supports only V4L ioctls, however it
-should work just fine with all V4L2 devices through the V4L2
-backward-compatibility layer. Since V4L2 permits multiple opens it is
-possible (if supported by the V4L2 driver) to capture video while an X
-client requested video overlay. Restrictions of simultaneous capturing
-and overlay are discussed in :ref:`overlay` apply.
-
-Only marginally related to V4L2, XFree86 extended Xv to support hardware
-YUV to RGB conversion and scaling for faster video playback, and added
-an interface to MPEG-2 decoding hardware. This API is useful to display
-images captured with V4L2 devices.
-
-
-Digital Video
--------------
-
-V4L2 does not support digital terrestrial, cable or satellite broadcast.
-A separate project aiming at digital receivers exists. You can find its
-homepage at `https://linuxtv.org <https://linuxtv.org>`__. The Linux
-DVB API has no connection to the V4L2 API except that drivers for hybrid
-hardware may support both.

-The V4L2 API defines several different methods to read from or write to
-a device. All drivers exchanging data with applications must support at
-least one of them.
-
-The classic I/O method using the :ref:`read() <func-read>` and
-:ref:`write() <func-write>` function is automatically selected after opening a
-V4L2 device. When the driver does not support this method attempts to
-read or write will fail at any time.
-
-Other methods must be negotiated. To select the streaming I/O method
-with memory mapped or user buffers applications call the
-:ref:`VIDIOC_REQBUFS` ioctl. The asynchronous I/O
-method is not defined yet.
-
-Video overlay can be considered another I/O method, although the
-application does not directly receive the image data. It is selected by
-initiating video overlay with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl. For more information see :ref:`overlay`.
-
-Generally exactly one I/O method, including overlay, is associated with
-each file descriptor. The only exceptions are applications not
-exchanging data with a driver ("panel applications", see :ref:`open`)
-and drivers permitting simultaneous video capturing and overlay using
-the same file descriptor, for compatibility with V4L and earlier
-versions of V4L2.
-
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_REQBUFS` would permit this to some
-degree, but for simplicity drivers need not support switching the I/O
-method (after first switching away from read/write) other than by
-closing and reopening the device.
-
-The following sections describe the various I/O methods in more detail.

-Introduction
-************
-
-libv4l is a collection of libraries which adds a thin abstraction layer
-on top of video4linux2 devices. The purpose of this (thin) layer is to
-make it easy for application writers to support a wide variety of
-devices without having to write separate code for different devices in
-the same class.
-
-An example of using libv4l is provided by
-:ref:`v4l2grab <v4l2grab-example>`.
-
-libv4l consists of 3 different libraries:
-
-
-libv4lconvert
-=============
-
-libv4lconvert is a library that converts several different pixelformats
-found in V4L2 drivers into a few common RGB and YUY formats.
-
-It currently accepts the following V4L2 driver formats:
-:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
-:ref:`V4L2_PIX_FMT_HM12 <V4L2-PIX-FMT-HM12>`,
-:ref:`V4L2_PIX_FMT_JPEG <V4L2-PIX-FMT-JPEG>`,
-:ref:`V4L2_PIX_FMT_MJPEG <V4L2-PIX-FMT-MJPEG>`,
-:ref:`V4L2_PIX_FMT_MR97310A <V4L2-PIX-FMT-MR97310A>`,
-:ref:`V4L2_PIX_FMT_OV511 <V4L2-PIX-FMT-OV511>`,
-:ref:`V4L2_PIX_FMT_OV518 <V4L2-PIX-FMT-OV518>`,
-:ref:`V4L2_PIX_FMT_PAC207 <V4L2-PIX-FMT-PAC207>`,
-:ref:`V4L2_PIX_FMT_PJPG <V4L2-PIX-FMT-PJPG>`,
-:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
-:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`,
-:ref:`V4L2_PIX_FMT_SGBRG8 <V4L2-PIX-FMT-SGBRG8>`,
-:ref:`V4L2_PIX_FMT_SGRBG8 <V4L2-PIX-FMT-SGRBG8>`,
-:ref:`V4L2_PIX_FMT_SN9C10X <V4L2-PIX-FMT-SN9C10X>`,
-:ref:`V4L2_PIX_FMT_SN9C20X_I420 <V4L2-PIX-FMT-SN9C20X-I420>`,
-:ref:`V4L2_PIX_FMT_SPCA501 <V4L2-PIX-FMT-SPCA501>`,
-:ref:`V4L2_PIX_FMT_SPCA505 <V4L2-PIX-FMT-SPCA505>`,
-:ref:`V4L2_PIX_FMT_SPCA508 <V4L2-PIX-FMT-SPCA508>`,
-:ref:`V4L2_PIX_FMT_SPCA561 <V4L2-PIX-FMT-SPCA561>`,
-:ref:`V4L2_PIX_FMT_SQ905C <V4L2-PIX-FMT-SQ905C>`,
-:ref:`V4L2_PIX_FMT_SRGGB8 <V4L2-PIX-FMT-SRGGB8>`,
-:ref:`V4L2_PIX_FMT_UYVY <V4L2-PIX-FMT-UYVY>`,
-:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`,
-:ref:`V4L2_PIX_FMT_YUYV <V4L2-PIX-FMT-YUYV>`,
-:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, and
-:ref:`V4L2_PIX_FMT_YVYU <V4L2-PIX-FMT-YVYU>`.
-
-Later on libv4lconvert was expanded to also be able to do various video
-processing functions to improve webcam video quality. The video
-processing is split in to 2 parts: libv4lconvert/control and
-libv4lconvert/processing.
-
-The control part is used to offer video controls which can be used to
-control the video processing functions made available by
-libv4lconvert/processing. These controls are stored application wide
-(until reboot) by using a persistent shared memory object.
-
-libv4lconvert/processing offers the actual video processing
-functionality.
-
-
-libv4l1
-=======
-
-This library offers functions that can be used to quickly make v4l1
-applications work with v4l2 devices. These functions work exactly like
-the normal open/close/etc, except that libv4l1 does full emulation of
-the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it will
-just pass calls through.
-
-Since those functions are emulations of the old V4L1 API, it shouldn't
-be used for new applications.
-
-
-libv4l2
-=======
-
-This library should be used for all modern V4L2 applications.
-
-It provides handles to call V4L2 open/ioctl/close/poll methods. Instead
-of just providing the raw output of the device, it enhances the calls in
-the sense that it will use libv4lconvert to provide more video formats
-and to enhance the image quality.
-
-In most cases, libv4l2 just passes the calls directly through to the
-v4l2 driver, intercepting the calls to
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`,
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`,
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
-:ref:`VIDIOC_ENUM_FRAMESIZES <VIDIOC_ENUM_FRAMESIZES>` and
-:ref:`VIDIOC_ENUM_FRAMEINTERVALS <VIDIOC_ENUM_FRAMEINTERVALS>` in
-order to emulate the formats
-:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
-:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
-:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`, and
-:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, if they aren't
-available in the driver. :ref:`VIDIOC_ENUM_FMT <VIDIOC_ENUM_FMT>`
-keeps enumerating the hardware supported formats, plus the emulated
-formats offered by libv4l at the end.
-
-
-.. _libv4l-ops:
-
-Libv4l device control functions
--------------------------------
-
-The common file operation methods are provided by libv4l.
-
-Those functions operate just like the gcc function ``dup()`` and
-V4L2 functions
-:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
-:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`read() <v4l2-read>`,
-:c:func:`mmap() <v4l2-mmap>` and :c:func:`munmap() <v4l2-munmap>`:
-
-.. c:function:: int v4l2_open(const char *file, int oflag, ...)
-
-   operates like the :c:func:`open() <v4l2-open>` function.
-
-.. c:function:: int v4l2_close(int fd)
-
-   operates like the :c:func:`close() <v4l2-close>` function.
-
-.. c:function:: int v4l2_dup(int fd)
-
-   operates like the libc ``dup()`` function, duplicating a file handler.
-
-.. c:function:: int v4l2_ioctl (int fd, unsigned long int request, ...)
-
-   operates like the :c:func:`ioctl() <v4l2-ioctl>` function.
-
-.. c:function:: int v4l2_read (int fd, void* buffer, size_t n)
-
-   operates like the :c:func:`read() <v4l2-read>` function.
-
-.. c:function:: void v4l2_mmap(void *start, size_t length, int prot, int flags, int fd, int64_t offset);
-
-   operates like the :c:func:`munmap() <v4l2-munmap>` function.
-
-.. c:function:: int v4l2_munmap(void *_start, size_t length);
-
-   operates like the :c:func:`munmap() <v4l2-munmap>` function.
-
-Those functions provide additional control:
-
-.. c:function:: int v4l2_fd_open(int fd, int v4l2_flags)
-
-   opens an already opened fd for further use through v4l2lib and possibly
-   modify libv4l2's default behavior through the ``v4l2_flags`` argument.
-   Currently, ``v4l2_flags`` can be ``V4L2_DISABLE_CONVERSION``, to disable
-   format conversion.
-
-.. c:function:: int v4l2_set_control(int fd, int cid, int value)
-
-   This function takes a value of 0 - 65535, and then scales that range to the
-   actual range of the given v4l control id, and then if the cid exists and is
-   not locked sets the cid to the scaled value.
-
-.. c:function:: int v4l2_get_control(int fd, int cid)
-
-   This function returns a value of 0 - 65535, scaled to from the actual range
-   of the given v4l control id. when the cid does not exist, could not be
-   accessed for some reason, or some error occurred 0 is returned.
-
-
-v4l1compat.so wrapper library
-=============================
-
-This library intercepts calls to
-:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
-:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`mmap() <v4l2-mmap>` and
-:c:func:`munmap() <v4l2-munmap>`
-operations and redirects them to the libv4l counterparts, by using
-``LD_PRELOAD=/usr/lib/v4l1compat.so``. It also emulates V4L1 calls via V4L2
-API.
-
-It allows usage of binary legacy applications that still don't use
-libv4l.

-******************************
-Streaming I/O (Memory Mapping)
-******************************
-
-Input and output devices support this I/O method when the
-``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl is set. There are two
-streaming methods, to determine if the memory mapping flavor is
-supported applications must call the :ref:`VIDIOC_REQBUFS` ioctl
-with the memory type set to ``V4L2_MEMORY_MMAP``.
-
-Streaming is an I/O method where only pointers to buffers are exchanged
-between application and driver, the data itself is not copied. Memory
-mapping is primarily intended to map buffers in device memory into the
-application's address space. Device memory can be for example the video
-memory on a graphics card with a video capture add-on. However, being
-the most efficient I/O method available for a long time, many other
-drivers support streaming as well, allocating buffers in DMA-able main
-memory.
-
-A driver can support many sets of buffers. Each set is identified by a
-unique buffer type value. The sets are independent and each set can hold
-a different type of data. To access different sets at the same time
-different file descriptors must be used. [#f1]_
-
-To allocate device buffers applications call the
-:ref:`VIDIOC_REQBUFS` ioctl with the desired number
-of buffers and buffer type, for example ``V4L2_BUF_TYPE_VIDEO_CAPTURE``.
-This ioctl can also be used to change the number of buffers or to free
-the allocated memory, provided none of the buffers are still mapped.
-
-Before applications can access the buffers they must map them into their
-address space with the :ref:`mmap() <func-mmap>` function. The
-location of the buffers in device memory can be determined with the
-:ref:`VIDIOC_QUERYBUF` ioctl. In the single-planar
-API case, the ``m.offset`` and ``length`` returned in a struct
-:c:type:`v4l2_buffer` are passed as sixth and second
-parameter to the :ref:`mmap() <func-mmap>` function. When using the
-multi-planar API, struct :c:type:`v4l2_buffer` contains an
-array of struct :c:type:`v4l2_plane` structures, each
-containing its own ``m.offset`` and ``length``. When using the
-multi-planar API, every plane of every buffer has to be mapped
-separately, so the number of calls to :ref:`mmap() <func-mmap>` should
-be equal to number of buffers times number of planes in each buffer. The
-offset and length values must not be modified. Remember, the buffers are
-allocated in physical memory, as opposed to virtual memory, which can be
-swapped out to disk. Applications should free the buffers as soon as
-possible with the :ref:`munmap() <func-munmap>` function.

-Conceptually streaming drivers maintain two buffer queues, an incoming
-and an outgoing queue. They separate the synchronous capture or output
-operation locked to a video clock from the application which is subject
-to random disk or network delays and preemption by other processes,
-thereby reducing the probability of data loss. The queues are organized
-as FIFOs, buffers will be output in the order enqueued in the incoming
-FIFO, and were captured in the order dequeued from the outgoing FIFO.
-
-The driver may require a minimum number of buffers enqueued at all times
-to function, apart of this no limit exists on the number of buffers
-applications can enqueue in advance, or dequeue and process. They can
-also enqueue in a different order than buffers have been dequeued, and
-the driver can *fill* enqueued *empty* buffers in any order.  [#f2]_ The
-index number of a buffer (struct :c:type:`v4l2_buffer`
-``index``) plays no role here, it only identifies the buffer.
-
-Initially all mapped buffers are in dequeued state, inaccessible by the
-driver. For capturing applications it is customary to first enqueue all
-mapped buffers, then to start capturing and enter the read loop. Here
-the application waits until a filled buffer can be dequeued, and
-re-enqueues the buffer when the data is no longer needed. Output
-applications fill and enqueue buffers, when enough buffers are stacked
-up the output is started with :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`.
-In the write loop, when the application runs out of free buffers, it
-must wait until an empty buffer can be dequeued and reused.
-
-To enqueue and dequeue a buffer applications use the
-:ref:`VIVIOC_QBUF <VIDIOC_QBUF>` and :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
-ioctl. The status of a buffer being mapped, enqueued, full or empty can
-be determined at any time using the :ref:`VIDIOC_QUERYBUF` ioctl. Two
-methods exist to suspend execution of the application until one or more
-buffers can be dequeued.  By default :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
-blocks when no buffer is in the outgoing queue. When the ``O_NONBLOCK``
-flag was given to the :ref:`open() <func-open>` function,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
-error code when no buffer is available. The :ref:`select() <func-select>`
-or :ref:`poll() <func-poll>` functions are always available.
-
-To start and stop capturing or output applications call the
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF
-<VIDIOC_STREAMON>` ioctl.
-
-.. note:::ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
-   removes all buffers from both queues as a side effect. Since there is
-   no notion of doing anything "now" on a multitasking system, if an
-   application needs to synchronize with another event it should examine
-   the struct ::c:type:`v4l2_buffer` ``timestamp`` of captured
-   or outputted buffers.
-
-Drivers implementing memory mapping I/O must support the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QUERYBUF
-<VIDIOC_QUERYBUF>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF
-<VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the :ref:`mmap()
-<func-mmap>`, :ref:`munmap() <func-munmap>`, :ref:`select()
-<func-select>` and :ref:`poll() <func-poll>` function. [#f3]_
-
-[capture example]
-
-.. [#f1]
-   One could use one file descriptor and set the buffer type field
-   accordingly when calling :ref:`VIDIOC_QBUF` etc.,
-   but it makes the :ref:`select() <func-select>` function ambiguous. We also
-   like the clean approach of one file descriptor per logical stream.
-   Video overlay for example is also a logical stream, although the CPU
-   is not needed for continuous operation.
-
-.. [#f2]
-   Random enqueue order permits applications processing images out of
-   order (such as video codecs) to return buffers earlier, reducing the
-   probability of data loss. Random fill order allows drivers to reuse
-   buffers on a LIFO-basis, taking advantage of caches holding
-   scatter-gather lists and the like.
-
-.. [#f3]
-   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
-   the same, and :ref:`select() <func-select>` is too important to be optional.
-   The rest should be evident.

-***************************
-Opening and Closing Devices
-***************************
-
-
-Device Naming
-=============
-
-V4L2 drivers are implemented as kernel modules, loaded manually by the
-system administrator or automatically when a device is first discovered.
-The driver modules plug into the "videodev" kernel module. It provides
-helper functions and a common application interface specified in this
-document.
-
-Each driver thus loaded registers one or more device nodes with major
-number 81 and a minor number between 0 and 255. Minor numbers are
-allocated dynamically unless the kernel is compiled with the kernel
-option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers
-are allocated in ranges depending on the device node type (video, radio,
-etc.).
-
-Many drivers support "video_nr", "radio_nr" or "vbi_nr" module
-options to select specific video/radio/vbi node numbers. This allows the
-user to request that the device node is named e.g. /dev/video5 instead
-of leaving it to chance. When the driver supports multiple devices of
-the same type more than one device node number can be assigned,
-separated by commas:
-
-.. code-block:: none
-
-   # modprobe mydriver video_nr=0,1 radio_nr=0,1
-
-In ``/etc/modules.conf`` this may be written as:
-
-::
-
-    options mydriver video_nr=0,1 radio_nr=0,1
-
-When no device node number is given as module option the driver supplies
-a default.
-
-Normally udev will create the device nodes in /dev automatically for
-you. If udev is not installed, then you need to enable the
-CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to
-correctly relate a minor number to a device node number. I.e., you need
-to be certain that minor number 5 maps to device node name video5. With
-this kernel option different device types have different minor number
-ranges. These ranges are listed in :ref:`devices`.
-
-The creation of character special files (with mknod) is a privileged
-operation and devices cannot be opened by major and minor number. That
-means applications cannot *reliably* scan for loaded or installed
-drivers. The user must enter a device name, or the application can try
-the conventional device names.
-
-
-.. _related:
-
-Related Devices
-===============
-
-Devices can support several functions. For example video capturing, VBI
-capturing and radio support.
-
-The V4L2 API creates different nodes for each of these functions.
-
-The V4L2 API was designed with the idea that one device node could
-support all functions. However, in practice this never worked: this
-'feature' was never used by applications and many drivers did not
-support it and if they did it was certainly never tested. In addition,
-switching a device node between different functions only works when
-using the streaming I/O API, not with the
-:ref:`read() <func-read>`/\ :ref:`write() <func-write>` API.
-
-Today each device node supports just one function.
-
-Besides video input or output the hardware may also support audio
-sampling or playback. If so, these functions are implemented as ALSA PCM
-devices with optional ALSA audio mixer devices.
-
-One problem with all these devices is that the V4L2 API makes no
-provisions to find these related devices. Some really complex devices
-use the Media Controller (see :ref:`media_controller`) which can be
-used for this purpose. But most drivers do not use it, and while some
-code exists that uses sysfs to discover related devices (see
-libmedia_dev in the
-`v4l-utils <http://git.linuxtv.org/cgit.cgi/v4l-utils.git/>`__ git
-repository), there is no library yet that can provide a single API
-towards both Media Controller-based devices and devices that do not use
-the Media Controller. If you want to work on this please write to the
-linux-media mailing list:
-`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
-
-
-Multiple Opens
-==============
-
-V4L2 devices can be opened more than once. [#f1]_ When this is supported
-by the driver, users can for example start a "panel" application to
-change controls like brightness or audio volume, while another
-application captures video and audio. In other words, panel applications
-are comparable to an ALSA audio mixer application. Just opening a V4L2
-device should not change the state of the device. [#f2]_
-
-Once an application has allocated the memory buffers needed for
-streaming data (by calling the :ref:`VIDIOC_REQBUFS`
-or :ref:`VIDIOC_CREATE_BUFS` ioctls, or
-implicitly by calling the :ref:`read() <func-read>` or
-:ref:`write() <func-write>` functions) that application (filehandle)
-becomes the owner of the device. It is no longer allowed to make changes
-that would affect the buffer sizes (e.g. by calling the
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl) and other applications are
-no longer allowed to allocate buffers or start or stop streaming. The
-EBUSY error code will be returned instead.
-
-Merely opening a V4L2 device does not grant exclusive access. [#f3]_
-Initiating data exchange however assigns the right to read or write the
-requested type of data, and to change related properties, to this file
-descriptor. Applications can request additional access privileges using
-the priority mechanism described in :ref:`app-pri`.
-
-
-Shared Data Streams
-===================
-
-V4L2 drivers should not support multiple applications reading or writing
-the same data stream on a device by copying buffers, time multiplexing
-or similar means. This is better handled by a proxy application in user
-space.
-
-
-Functions
-=========
-
-To open and close V4L2 devices applications use the
-:ref:`open() <func-open>` and :ref:`close() <func-close>` function,
-respectively. Devices are programmed using the
-:ref:`ioctl() <func-ioctl>` function as explained in the following
-sections.
-
-.. [#f1]
-   There are still some old and obscure drivers that have not been
-   updated to allow for multiple opens. This implies that for such
-   drivers :ref:`open() <func-open>` can return an ``EBUSY`` error code
-   when the device is already in use.
-
-.. [#f2]
-   Unfortunately, opening a radio device often switches the state of the
-   device to radio mode in many drivers. This behavior should be fixed
-   eventually as it violates the V4L2 specification.
-
-.. [#f3]
-   Drivers could recognize the ``O_EXCL`` open flag. Presently this is
-   not required, so applications cannot know if it really works.

-**********************
-Standard Image Formats
-**********************
-
-In order to exchange images between drivers and applications, it is
-necessary to have standard image data formats which both sides will
-interpret the same way. V4L2 includes several such formats, and this
-section is intended to be an unambiguous specification of the standard
-image data formats in V4L2.
-
-V4L2 drivers are not limited to these formats, however. Driver-specific
-formats are possible. In that case the application may depend on a codec
-to convert images to one of the standard formats when needed. But the
-data can still be stored and retrieved in the proprietary format. For
-example, a device may support a proprietary compressed format.
-Applications can still capture and save the data in the compressed
-format, saving much disk space, and later use a codec to convert the
-images to the X Windows screen format when the video is to be displayed.
-
-Even so, ultimately, some standard formats are needed, so the V4L2
-specification would not be complete without well-defined standard
-formats.
-
-The V4L2 standard formats are mainly uncompressed formats. The pixels
-are always arranged in memory from left to right, and from top to
-bottom. The first byte of data in the image buffer is always for the
-leftmost pixel of the topmost row. Following that is the pixel
-immediately to its right, and so on until the end of the top row of
-pixels. Following the rightmost pixel of the row there may be zero or
-more bytes of padding to guarantee that each row of pixel data has a
-certain alignment. Following the pad bytes, if any, is data for the
-leftmost pixel of the second row from the top, and so on. The last row
-has just as many pad bytes after it as the other rows.
-
-In V4L2 each format has an identifier which looks like ``PIX_FMT_XXX``,
-defined in the :ref:`videodev2.h <videodev>` header file. These
-identifiers represent
-:ref:`four character (FourCC) codes <v4l2-fourcc>` which are also
-listed below, however they are not the same as those used in the Windows
-world.
-
-For some formats, data is stored in separate, discontiguous memory
-buffers. Those formats are identified by a separate set of FourCC codes
-and are referred to as "multi-planar formats". For example, a
-:ref:`YUV422 <V4L2-PIX-FMT-YUV422M>` frame is normally stored in one
-memory buffer, but it can also be placed in two or three separate
-buffers, with Y component in one buffer and CbCr components in another
-in the 2-planar version or with each component in its own buffer in the
-3-planar case. Those sub-buffers are referred to as "*planes*".

-Description
-===========
-
-M420 is a YUV format with ½ horizontal and vertical chroma subsampling
-(YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
-Two lines of luma data are followed by one line of chroma data.

-Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
-Y'\ :sub:`10`, Y'\ :sub:`11`.
-
-All line lengths are identical: if the Y lines include pad bytes so do
-the CbCr lines.

-Intel D4xx UVC Cameras Metadata
-
-
-Description
-===========
-
-Intel D4xx (D435 and other) cameras include per-frame metadata in their UVC
-payload headers, following the Microsoft(R) UVC extension proposal [1_]. That
-means, that the private D4XX metadata, following the standard UVC header, is
-organised in blocks. D4XX cameras implement several standard block types,
-proposed by Microsoft, and several proprietary ones. Supported standard metadata
-types are MetadataId_CaptureStats (ID 3), MetadataId_CameraExtrinsics (ID 4),
-and MetadataId_CameraIntrinsics (ID 5). For their description see [1_]. This
-document describes proprietary metadata types, used by D4xx cameras.
-
-V4L2_META_FMT_D4XX buffers follow the metadata buffer layout of
-V4L2_META_FMT_UVC with the only difference, that it also includes proprietary
-payload header data. D4xx cameras use bulk transfers and only send one payload
-per frame, therefore their headers cannot be larger than 255 bytes.
-
-Below are proprietary Microsoft style metadata types, used by D4xx cameras,
-where all fields are in little endian order:
-
-.. tabularcolumns:: |p{5.0cm}|p{12.5cm}|

-3A statistics
-=============
-
-The IPU3 ImgU 3A statistics accelerators collect different statistics over
-an input Bayer frame. Those statistics are obtained from the "ipu3-imgu [01] 3a
-stat" metadata capture video nodes, using the :c:type:`v4l2_meta_format`
-interface. They are formatted as described by the :c:type:`ipu3_uapi_stats_3a`
-structure.
-
-The statistics collected are AWB (Auto-white balance) RGBS (Red, Green, Blue and
-Saturation measure) cells, AWB filter response, AF (Auto-focus) filter response,
-and AE (Auto-exposure) histogram.
-
-The struct :c:type:`ipu3_uapi_4a_config` saves all configurable parameters.

-formatted as described by the :c:type:`ipu3_uapi_params` structure.
-
-Both 3A statistics and pipeline parameters described here are closely tied to
-the underlying camera sub-system (CSS) APIs. They are usually consumed and
-produced by dedicated user space libraries that comprise the important tuning
-tools, thus freeing the developers from being bothered with the low level
-hardware and algorithm details.

-UVC Payload Header Data
-
-
-Description
-===========
-
-This format describes standard UVC metadata, extracted from UVC packet headers
-and provided by the UVC driver through metadata video nodes. That data includes
-exact copies of the standard part of UVC Payload Header contents and auxiliary
-timing information, required for precise interpretation of timestamps, contained
-in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
-the "UVC 1.5 Class specification" for details.
-
-Each UVC payload header can be between 2 and 12 bytes large. Buffers can
-contain multiple headers, if multiple such headers have been transmitted by the
-camera for the respective frame. However, the driver may drop headers when the
-buffer is full, when they contain no useful information (e.g. those without the
-SCR field or with that field identical to the previous header), or generally to
-perform rate limiting when the device sends a large number of headers.
-
-Each individual block contains the following fields:
-
-.. flat-table:: UVC Metadata Block
-    :widths: 1 4
-    :header-rows:  1
-    :stub-columns: 0
-
-    * - Field
-      - Description
-    * - __u64 ts;
-      - system timestamp in host byte order, measured by the driver upon
-        reception of the payload
-    * - __u16 sof;
-      - USB Frame Number in host byte order, also obtained by the driver as
-        close as possible to the above timestamp to enable correlation between
-        them
-    * - :cspan:`1` *The rest is an exact copy of the UVC payload header:*
-    * - __u8 length;
-      - length of the rest of the block, including this field
-    * - __u8 flags;
-      - Flags, indicating presence of other standard UVC fields
-    * - __u8 buf[];
-      - The rest of the header, possibly including UVC PTS and SCR fields

-
-
-Description
-===========
-
-This format describes histogram data generated by the Renesas R-Car VSP1 1-D
-Histogram (HGO) engine.
-
-The VSP1 HGO is a histogram computation engine that can operate on RGB, YCrCb
-or HSV data. It operates on a possibly cropped and subsampled input image and
-computes the minimum, maximum and sum of all pixels as well as per-channel
-histograms.
-
-The HGO can compute histograms independently per channel, on the maximum of the
-three channels (RGB data only) or on the Y channel only (YCbCr only). It can
-additionally output the histogram with 64 or 256 bins, resulting in four
-possible modes of operation.
-
-- In *64 bins normal mode*, the HGO operates on the three channels independently
-  to compute three 64-bins histograms. RGB, YCbCr and HSV image formats are
-  supported.
-- In *64 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
-  channels to compute a single 64-bins histogram. Only the RGB image format is
-  supported.
-- In *256 bins normal mode*, the HGO operates on the Y channel to compute a
-  single 256-bins histogram. Only the YCbCr image format is supported.
-- In *256 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
-  channels to compute a single 256-bins histogram. Only the RGB image format is
-  supported.
-
-**Byte Order.**
-All data is stored in memory in little endian format. Each cell in the tables
-contains one byte.

-Renesas R-Car VSP1 2-D Histogram Data
-
-
-Description
-===========
-
-This format describes histogram data generated by the Renesas R-Car VSP1
-2-D Histogram (HGT) engine.
-
-The VSP1 HGT is a histogram computation engine that operates on HSV
-data. It operates on a possibly cropped and subsampled input image and
-computes the sum, maximum and minimum of the S component as well as a
-weighted frequency histogram based on the H and S components.
-
-The histogram is a matrix of 6 Hue and 32 Saturation buckets, 192 in
-total. Each HSV value is added to one or more buckets with a weight
-between 1 and 16 depending on the Hue areas configuration. Finding the
-corresponding buckets is done by inspecting the H and S value independently.
-
-The Saturation position **n** (0 - 31) of the bucket in the matrix is
-found by the expression:
-
-    n = S / 8
-
-The Hue position **m** (0 - 5) of the bucket in the matrix depends on
-how the HGT Hue areas are configured. There are 6 user configurable Hue
-Areas which can be configured to cover overlapping Hue values:

-
-When two consecutive areas don't overlap (n+1L is equal to nU) the boundary
-value is considered as part of the lower area.
-
-Pixels with a hue value included in the centre of an area (between nL and nU
-included) are attributed to that single area and given a weight of 16. Pixels
-with a hue value included in the overlapping region between two areas (between
-n+1L and nU excluded) are attributed to both areas and given a weight for each
-of these areas proportional to their position along the diagonal lines
-(rounded down).
-
-The Hue area setup must match one of the following constrains:
-
-::
-
-    0L <= 0U <= 1L <= 1U <= 2L <= 2U <= 3L <= 3U <= 4L <= 4U <= 5L <= 5U

-V4L2_PIX_FMT_NV21
-Formats with ½ horizontal and vertical chroma resolution, also known as
-YUV 4:2:0. One luminance and one chrominance plane with alternating
-chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
-
-
-Description
-===========
-
-These are two-plane versions of the YUV 4:2:0 format. The three
-components are separated into two sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
-combined CbCr plane immediately follows the Y plane in memory. The CbCr
-plane is the same width, in bytes, as the Y plane (and of the image),
-but is half as tall in pixels. Each CbCr pair belongs to four pixels.
-For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
-Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`. ``V4L2_PIX_FMT_NV21`` is
-the same except the Cb and Cr bytes are swapped, the CrCb plane starts
-with a Cr byte.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has as
-many pad bytes after its rows.
-
-**Byte Order.**
-Each cell is one byte.

-Variation of ``V4L2_PIX_FMT_NV12`` and ``V4L2_PIX_FMT_NV21`` with planes
-non contiguous in memory.
-
-
-Description
-===========
-
-This is a multi-planar, two-plane version of the YUV 4:2:0 format. The
-three components are separated into two sub-images or planes.
-``V4L2_PIX_FMT_NV12M`` differs from ``V4L2_PIX_FMT_NV12`` in that the
-two planes are non-contiguous in memory, i.e. the chroma plane do not
-necessarily immediately follows the luma plane. The luminance data
-occupies the first plane. The Y plane has one byte per pixel. In the
-second plane there is a chrominance data with alternating chroma
-samples. The CbCr plane is the same width, in bytes, as the Y plane (and
-of the image), but is half as tall in pixels. Each CbCr pair belongs to
-four pixels. For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to
-Y'\ :sub:`00`, Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
-``V4L2_PIX_FMT_NV12MT_16X16`` is the tiled version of
-``V4L2_PIX_FMT_NV12M`` with 16x16 macroblock tiles. Here pixels are
-arranged in 16x16 2D tiles and tiles are arranged in linear order in
-memory. ``V4L2_PIX_FMT_NV21M`` is the same as ``V4L2_PIX_FMT_NV12M``
-except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr
-byte.
-
-``V4L2_PIX_FMT_NV12M`` is intended to be used only in drivers and
-applications that support the multi-planar API, described in
-:ref:`planar-apis`.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has as
-many pad bytes after its rows.
-
-**Byte Order.**
-Each cell is one byte.

-Formats with ½ horizontal and vertical chroma resolution. This format
-has two planes - one for luminance and one for chrominance. Chroma
-samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
-memory layout. Pixels are grouped in macroblocks of 64x32 size. The
-order of macroblocks in memory is also not standard.
-
-
-Description
-===========
-
-This is the two-plane versions of the YUV 4:2:0 format where data is
-grouped into 64x32 macroblocks. The three components are separated into
-two sub-images or planes. The Y plane has one byte per pixel and pixels
-are grouped into 64x32 macroblocks. The CbCr plane has the same width,
-in bytes, as the Y plane (and the image), but is half as tall in pixels.
-The chroma plane is also grouped into 64x32 macroblocks.
-
-Width of the buffer has to be aligned to the multiple of 128, and height
-alignment is 32. Every four adjacent buffers - two horizontally and two
-vertically are grouped together and are located in memory in Z or
-flipped Z order.
-
-Layout of macroblocks in memory is presented in the following figure.

-
-    V4L2_PIX_FMT_NV12MT macroblock Z shape memory layout
-
-The requirement that width is multiple of 128 is implemented because,
-the Z shape cannot be cut in half horizontally. In case the vertical
-resolution of macroblocks is odd then the last row of macroblocks is
-arranged in a linear order.
-
-In case of chroma the layout is identical. Cb and Cr samples are
-interleaved. Height of the buffer is aligned to 32.

-V4L2_PIX_FMT_NV61
-Formats with ½ horizontal chroma resolution, also known as YUV 4:2:2.
-One luminance and one chrominance plane with alternating chroma samples
-as opposed to ``V4L2_PIX_FMT_YVU420``
-
-
-Description
-===========
-
-These are two-plane versions of the YUV 4:2:2 format. The three
-components are separated into two sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV16``, a
-combined CbCr plane immediately follows the Y plane in memory. The CbCr
-plane is the same width and height, in bytes, as the Y plane (and of the
-image). Each CbCr pair belongs to two pixels. For example,
-Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`.
-``V4L2_PIX_FMT_NV61`` is the same except the Cb and Cr bytes are
-swapped, the CrCb plane starts with a Cr byte.
-
-If the Y plane has pad bytes after each row, then the CbCr plane has as
-many pad bytes after its rows.
-
-**Byte Order.**
-Each cell is one byte.

-V4L2_PIX_FMT_NV61M
-Variation of ``V4L2_PIX_FMT_NV16`` and ``V4L2_PIX_FMT_NV61`` with planes
-non contiguous in memory.
-
-
-Description
-===========
-
-This is a multi-planar, two-plane version of the YUV 4:2:2 format. The
-three components are separated into two sub-images or planes.
-``V4L2_PIX_FMT_NV16M`` differs from ``V4L2_PIX_FMT_NV16`` in that the
-two planes are non-contiguous in memory, i.e. the chroma plane does not
-necessarily immediately follow the luma plane. The luminance data
-occupies the first plane. The Y plane has one byte per pixel. In the
-second plane there is chrominance data with alternating chroma samples.
-The CbCr plane is the same width and height, in bytes, as the Y plane.
-Each CbCr pair belongs to two pixels. For example,
-Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`.
-``V4L2_PIX_FMT_NV61M`` is the same as ``V4L2_PIX_FMT_NV16M`` except the
-Cb and Cr bytes are swapped, the CrCb plane starts with a Cr byte.
-
-``V4L2_PIX_FMT_NV16M`` and ``V4L2_PIX_FMT_NV61M`` are intended to be
-used only in drivers and applications that support the multi-planar API,
-described in :ref:`planar-apis`.
-
-**Byte Order.**
-Each cell is one byte.

-
-      - ``V4L2_PIX_FMT_S5C_UYVY_JPG``
-      - 'S5CI'
-      - Two-planar format used by Samsung S5C73MX cameras. The first plane
-	contains interleaved JPEG and UYVY image data, followed by meta
-	data in form of an array of offsets to the UYVY data blocks. The
-	actual pointer array follows immediately the interleaved JPEG/UYVY
-	data, the number of entries in this array equals the height of the
-	UYVY image. Each entry is a 4-byte unsigned integer in big endian
-	order and it's an offset to a single pixel line of the UYVY image.
-	The first plane can start either with JPEG or UYVY data chunk. The
-	size of a single UYVY block equals the UYVY image's width
-	multiplied by 2. The size of a JPEG chunk depends on the image and
-	can vary with each line.
-
-	The second plane, at an offset of 4084 bytes, contains a 4-byte
-	offset to the pointer array in the first plane. This offset is
-	followed by a 4-byte value indicating size of the pointer array.
-	All numbers in the second plane are also in big endian order.
-	Remaining data in the second plane is undefined. The information
-	in the second plane allows to easily find location of the pointer
-	array, which can be different for each frame. The size of the
-	pointer array is constant for given UYVY image height.
-
-	In order to extract UYVY and JPEG frames an application can
-	initially set a data pointer to the start of first plane and then
-	add an offset from the first entry of the pointers table. Such a
-	pointer indicates start of an UYVY image pixel line. Whole UYVY
-	line can be copied to a separate buffer. These steps should be
-	repeated for each line, i.e. the number of entries in the pointer
-	array. Anything what's in between the UYVY lines is JPEG data and
-	should be concatenated to form the JPEG stream.

-	The compression is lossless.
-	It is an opaque intermediate format and the MDP hardware must be
-	used to convert ``V4L2_PIX_FMT_MT21C`` to ``V4L2_PIX_FMT_NV12M``,
-	``V4L2_PIX_FMT_YUV420M`` or ``V4L2_PIX_FMT_YVU420``.

-
-      - ``V4L2_PIX_FMT_SUNXI_TILED_NV12``
-      - 'ST12'
-      - Two-planar NV12-based format used by the video engine found on Allwinner
-	(codenamed sunxi) platforms, with 32x32 tiles for the luminance plane
-	and 32x64 tiles for the chrominance plane. The data in each tile is
-	stored in linear order, within the tile bounds. Each tile follows the
-	previous one linearly in memory (from left to right, top to bottom).
-
-	The associated buffer dimensions are aligned to match an integer number
-	of tiles, resulting in 32-aligned resolutions for the luminance plane
-	and 16-aligned resolutions for the chrominance plane (with 2x2
-	subsampling).

-Description
-===========
-
-These formats are designed to match the pixel formats of typical PC
-graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
-These are all packed-pixel formats, meaning all the data for a pixel lie
-next to each other in memory.

-capture queues of mem-to-mem devices) fill the alpha component in
-memory. When the device outputs an alpha channel the alpha component
-will have a meaningful value. Otherwise, when the device doesn't output
-an alpha channel but can set the alpha bit to a user-configurable value,
-the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
-is used to specify that alpha value, and the alpha component of all
-pixels will be set to the value specified by that control. Otherwise a
-corresponding format without an alpha component (XRGB or XBGR) must be
-used instead of an alpha format.
-
-:ref:`Output <output>` devices (including output queues of mem-to-mem
-devices and :ref:`video output overlay <osd>` devices) read the alpha
-component from memory. When the device processes the alpha channel the
-alpha component must be filled with meaningful values by applications.
-Otherwise a corresponding format without an alpha component (XRGB or
-XBGR) must be used instead of an alpha format.
-
-The XRGB and XBGR formats contain undefined bits (-). Applications,
-devices and drivers must ignore those bits, for both
-:ref:`capture` and :ref:`output` devices.

-Planar complex unsigned 18-bit big endian IQ sample
-
-Description
-===========
-
-This format contains a sequence of complex number samples. Each complex
-number consist of two parts called In-phase and Quadrature (IQ). Both I
-and Q are represented as a 18 bit unsigned big endian number stored in
-32 bit space. The remaining unused bits within the 32 bit space will be
-padded with 0. I value starts first and Q value starts at an offset
-equalling half of the buffer size (i.e.) offset = buffersize/2. Out of
-the 18 bits, bit 17:2 (16 bit) is data and bit 1:0 (2 bit) can be any
-value.

-**Byte Order.**

-10-bit Bayer formats
-
-Description
-===========
-
-These four pixel formats are used by Intel IPU3 driver, they are raw
-sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
-to 32 bytes leaving 6 most significant bits padding in the last byte.
-The format is little endian.
-
-In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
-Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
-
-**Byte Order.**
-Each cell is one byte.

-high bits filled with zeros. Each n-pixel row contains n/2 green samples and
-n/2 blue or red samples, with alternating red and blue rows. Bytes are
-stored in memory in little endian order. They are conventionally described
-as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of
-these formats:

-14-bit Bayer formats expanded to 16 bits
-
-
-Description
-===========
-
-These four pixel formats are raw sRGB / Bayer formats with 14 bits per
-colour. Each sample is stored in a 16-bit word, with two unused high
-bits filled with zeros. Each n-pixel row contains n/2 green samples
-and n/2 blue or red samples, with alternating red and blue rows. Bytes
-are stored in memory in little endian order. They are conventionally
-described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an
-example of a small V4L2_PIX_FMT_SBGGR14 image:
-
-**Byte Order.**
-Each cell is one byte, the two most significant bits in the high bytes are
-zero.

-Description
-===========
-
-These four pixel formats are packed raw sRGB / Bayer formats with 14
-bits per colour. Every four consecutive samples are packed into seven
-bytes. Each of the first four bytes contain the eight high order bits
-of the pixels, and the three following bytes contains the six least
-significants bits of each pixel, in the same order.
-
-Each n-pixel row contains n/2 green samples and n/2 blue or red samples,
-with alternating green-red and green-blue rows. They are conventionally
-described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example

-      - Image height in pixels. If ``field`` is one of ``V4L2_FIELD_TOP``,
-	``V4L2_FIELD_BOTTOM`` or ``V4L2_FIELD_ALTERNATE`` then height
-	refers to the number of lines in the field, otherwise it refers to
-	the number of lines in the frame (which is twice the field height
-	for interlaced formats).
-    * - :cspan:`2` Applications set these fields to request an image
-	size, drivers return the closest possible values. In case of

-	plane. To avoid ambiguities drivers must return values rounded up
-	to a multiple of the scale factor of any smaller planes. For
-	example when the image format is YUV 4:2:0, ``width`` and
-	``height`` must be multiples of two.
-
-	For compressed formats that contain the resolution information encoded

-      - ``field``
-      - Field order, from enum :c:type:`v4l2_field`.
-        Video images are typically interlaced. Applications can request to
-	capture or output only the top or bottom field, or both fields
-	interlaced or sequentially stored in one buffer or alternating in
-	separate buffers. Drivers return the actual field order selected.

-      - ``bytesperline``
-      - Distance in bytes between the leftmost pixels in two adjacent
-	lines.
-    * - :cspan:`2`
-
-	Both applications and drivers can set this field to request
-	padding bytes at the end of each line. Drivers however may ignore
-	the value requested by the application, returning ``width`` times
-	bytes per pixel or a larger value required by the hardware. That
-	implies applications can just set this field to zero to get a
-	reasonable default.
-
-	Video hardware may access padding bytes, therefore they must

-	after the last line of an image cross a system page boundary.
-	Input devices may write padding bytes, the value is undefined.
-	Output devices ignore the contents of padding bytes.
-
-	When the image format is planar the ``bytesperline`` value applies
-	to the first plane and is divided by the same factor as the
-	``width`` field for the other planes. For example the Cb and Cr
-	planes of a YUV 4:2:0 image have half as many padding bytes
-	following each line as the Y plane. To avoid ambiguities drivers
-	must return a ``bytesperline`` value rounded up to a multiple of
-	the scale factor.
-
-	For compressed formats the ``bytesperline`` value makes no sense.
-	Applications and drivers must set this to 0 in that case.
-    * - __u32
-      - ``sizeimage``
-      - Size in bytes of the buffer to hold a complete image, set by the
-	driver. Usually this is ``bytesperline`` times ``height``. When
-	the image consists of variable length compressed data this is the
-	number of bytes required by the codec to support the worst-case
-	compression scenario.
-
-	The driver will set the value for uncompressed images.
-
-	Clients are allowed to set the sizeimage field for variable length
-	compressed data flagged with ``V4L2_FMT_FLAG_COMPRESSED`` at
-	:ref:`VIDIOC_ENUM_FMT`, but the driver may ignore it and set the
-	value itself, or it may modify the provided value based on
-	alignment requirements or minimum/maximum size requirements.
-	If the client wants to leave this to the driver, then it should
-	set sizeimage to 0.
-    * - __u32
-      - ``colorspace``
-      - Image colorspace, from enum :c:type:`v4l2_colorspace`.
-        This information supplements the ``pixelformat`` and must be set
-	by the driver for capture streams and by the application for
-	output streams, see :ref:`colorspaces`.
-    * - __u32
-      - ``priv``
-      - This field indicates whether the remaining fields of the
-	struct :c:type:`v4l2_pix_format`, also called the
-	extended fields, are valid. When set to
-	``V4L2_PIX_FMT_PRIV_MAGIC``, it indicates that the extended fields
-	have been correctly initialized. When set to any other value it
-	indicates that the extended fields contain undefined values.
-
-	Applications that wish to use the pixel format extended fields
-	must first ensure that the feature is supported by querying the
-	device for the :ref:`V4L2_CAP_EXT_PIX_FORMAT <querycap>`
-	capability. If the capability isn't set the pixel format extended
-	fields are not supported and using the extended fields will lead
-	to undefined results.
-
-	To use the extended fields, applications must set the ``priv``
-	field to ``V4L2_PIX_FMT_PRIV_MAGIC``, initialize all the extended
-	fields and zero the unused bytes of the
-	struct :c:type:`v4l2_format` ``raw_data`` field.
-
-	When the ``priv`` field isn't set to ``V4L2_PIX_FMT_PRIV_MAGIC``
-	drivers must act as if all the extended fields were set to zero.
-	On return drivers must set the ``priv`` field to
-	``V4L2_PIX_FMT_PRIV_MAGIC`` and all the extended fields to
-	applicable values.

-Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1
-
-
-Description
-===========
-
-In this format each 12 bytes is eight pixels. In the twelve bytes are
-two CbCr pairs and eight Y's. The first CbCr pair goes with the first
-four Y's, and the second CbCr pair goes with the other four Y's. The Cb
-and Cr components have one fourth the horizontal resolution of the Y
-component.
-
-Do not confuse this format with
-:ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
-from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1

-V4L2_PIX_FMT_YUV410
-Planar formats with ¼ horizontal and vertical chroma resolution, also
-known as YUV 4:1:0
-
-
-Description
-===========
-
-These are planar formats, as opposed to a packed format. The three
-components are separated into three sub-images or planes. The Y plane is
-first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
-the Cr plane immediately follows the Y plane in memory. The Cr plane is
-¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
-belongs to 16 pixels, a four-by-four square of the image. Following the
-Cr plane is the Cb plane, just like the Cr plane.
-``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
-then the Cr plane.
-
-If the Y plane has pad bytes after each row, then the Cr and Cb planes
-have ¼ as many pad bytes after their rows. In other words, four Cx rows
-(including padding) are exactly as long as one Y row (including
-padding).
-
-**Byte Order.**
-Each cell is one byte.

-===========
-
-This format is not commonly used. This is a planar format similar to the

-V4L2_PIX_FMT_YUV420
-Planar formats with ½ horizontal and vertical chroma resolution, also
-known as YUV 4:2:0
-
-
-Description
-===========
-
-These are planar formats, as opposed to a packed format. The three
-components are separated into three sub- images or planes. The Y plane
-is first. The Y plane has one byte per pixel. For
-``V4L2_PIX_FMT_YVU420``, the Cr plane immediately follows the Y plane in
-memory. The Cr plane is half the width and half the height of the Y
-plane (and of the image). Each Cr belongs to four pixels, a two-by-two
-square of the image. For example, Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
-Y'\ :sub:`01`, Y'\ :sub:`10`, and Y'\ :sub:`11`. Following the Cr plane
-is the Cb plane, just like the Cr plane. ``V4L2_PIX_FMT_YUV420`` is the
-same except the Cb plane comes first, then the Cr plane.
-
-If the Y plane has pad bytes after each row, then the Cr and Cb planes
-have half as many pad bytes after their rows. In other words, two Cx
-rows (including padding) is exactly as long as one Y row (including
-padding).

-V4L2_PIX_FMT_YVU444M
-Planar formats with full horizontal resolution, also known as YUV and
-YVU 4:4:4
-
-
-Description
-===========
-
-This is a multi-planar format, as opposed to a packed format. The three
-components are separated into three sub-images or planes.
-
-The Y plane is first. The Y plane has one byte per pixel. For
-``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which
-is the same width and height as the Y plane (and as the image). The Cr
-data, just like the Cb plane, is in the third plane.
-
-``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the
-second plane and the Cb data in the third plane.
-
-If the Y plane has pad bytes after each row, then the Cb and Cr planes
-have the same number of pad bytes after their rows.
-
-``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be
-used only in drivers and applications that support the multi-planar API,
-described in :ref:`planar-apis`.
-
-**Byte Order.**
-Each cell is one byte.

-The V4L2 API was primarily designed for devices exchanging image data
-with applications. The struct :c:type:`v4l2_pix_format` and
-struct :c:type:`v4l2_pix_format_mplane` structures define the
-format and layout of an image in memory. The former is used with the
-single-planar API, while the latter is used with the multi-planar
-version (see :ref:`planar-apis`). Image formats are negotiated with
-the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. (The explanations here
-focus on video capturing and output, for overlay frame buffer formats
-see also :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`.)

-Single- and multi-planar APIs
-*****************************
-
-Some devices require data for each input or output video frame to be
-placed in discontiguous memory buffers. In such cases, one video frame
-has to be addressed using more than one memory address, i.e. one pointer
-per "plane". A plane is a sub-buffer of the current frame. For examples
-of such formats see :ref:`pixfmt`.
-
-Initially, V4L2 API did not support multi-planar buffers and a set of
-extensions has been introduced to handle them. Those extensions
-constitute what is being referred to as the "multi-planar API".
-
-Some of the V4L2 API calls and structures are interpreted differently,
-depending on whether single- or multi-planar API is being used. An
-application can choose whether to use one or the other by passing a
-corresponding buffer type to its ioctl calls. Multi-planar versions of
-buffer types are suffixed with an ``_MPLANE`` string. For a list of
-available multi-planar buffer types see enum
-:c:type:`v4l2_buf_type`.
-
-
-Multi-planar formats
-====================
-
-Multi-planar API introduces new multi-planar formats. Those formats use
-a separate set of FourCC codes. It is important to distinguish between
-the multi-planar API and a multi-planar format. Multi-planar API calls
-can handle all single-planar formats as well (as long as they are passed
-in multi-planar API structures), while the single-planar API cannot
-handle multi-planar formats.
-
-
-Calls that distinguish between single and multi-planar APIs
-===========================================================
-
-:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>`
-    Two additional multi-planar capabilities are added. They can be set
-    together with non-multi-planar ones for devices that handle both
-    single- and multi-planar formats.
-
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`
-    New structures for describing multi-planar formats are added: struct
-    :c:type:`v4l2_pix_format_mplane` and
-    struct :c:type:`v4l2_plane_pix_format`.
-    Drivers may define new multi-planar formats, which have distinct
-    FourCC codes from the existing single-planar ones.
-
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>`
-    A new struct :c:type:`v4l2_plane` structure for
-    describing planes is added. Arrays of this structure are passed in
-    the new ``m.planes`` field of struct
-    :c:type:`v4l2_buffer`.
-
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
-    Will allocate multi-planar buffers as requested.

-Querying Capabilities
-*********************
-
-Because V4L2 covers a wide variety of devices not all aspects of the API
-are equally applicable to all types of devices. Furthermore devices of
-the same type have different capabilities and this specification permits
-the omission of a few complicated and less important parts of the API.
-
-The :ref:`VIDIOC_QUERYCAP` ioctl is available to
-check if the kernel device is compatible with this specification, and to
-query the :ref:`functions <devices>` and :ref:`I/O methods <io>`
-supported by the device.
-
-Starting with kernel version 3.1, :ref:`VIDIOC_QUERYCAP`
-will return the V4L2 API version used by the driver, with generally
-matches the Kernel version. There's no need of using
-:ref:`VIDIOC_QUERYCAP` to check if a specific ioctl
-is supported, the V4L2 core now returns ``ENOTTY`` if a driver doesn't
-provide support for an ioctl.
-
-Other features can be queried by calling the respective ioctl, for
-example :ref:`VIDIOC_ENUMINPUT` to learn about the
-number, types and names of video connectors on the device. Although
-abstraction is a major objective of this API, the
-:ref:`VIDIOC_QUERYCAP` ioctl also allows driver
-specific applications to reliably identify the driver.
-
-All V4L2 drivers must support :ref:`VIDIOC_QUERYCAP`.
-Applications should always call this ioctl after opening the device.

-Read/Write
-**********
-
-Input and output devices support the :ref:`read() <func-read>` and
-:ref:`write() <func-write>` function, respectively, when the
-``V4L2_CAP_READWRITE`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl is set.
-
-Drivers may need the CPU to copy the data, but they may also support DMA
-to or from user memory, so this I/O method is not necessarily less
-efficient than other methods merely exchanging buffer pointers. It is
-considered inferior though because no meta-information like frame
-counters or timestamps are passed. This information is necessary to
-recognize frame dropping and to synchronize with other data streams.
-However this is also the simplest I/O method, requiring little or no
-setup to exchange data. It permits command line stunts like this (the
-vidctrl tool is fictitious):
-
-
-.. code-block:: none
-
-    $ vidctrl /dev/video --input=0 --format=YUYV --size=352x288
-    $ dd if=/dev/video of=myimage.422 bs=202752 count=1
-
-To read from the device applications use the :ref:`read() <func-read>`
-function, to write the :ref:`write() <func-write>` function. Drivers
-must implement one I/O method if they exchange data with applications,
-but it need not be this. [#f1]_ When reading or writing is supported, the
-driver must also support the :ref:`select() <func-select>` and
-:ref:`poll() <func-poll>` function. [#f2]_
-
-.. [#f1]
-   It would be desirable if applications could depend on drivers
-   supporting all I/O interfaces, but as much as the complex memory
-   mapping I/O can be inadequate for some devices we have no reason to
-   require this interface, which is most useful for simple applications
-   capturing still images.
-
-.. [#f2]
-   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
-   the same, and :ref:`select() <func-select>` is too important to be optional.

-*************
-Configuration
-*************
-
-Applications can use the :ref:`selection API <VIDIOC_G_SELECTION>` to
-select an area in a video signal or a buffer, and to query for default
-settings and hardware limits.
-
-Video hardware can have various cropping, composing and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in the horizontal and
-vertical directions. Also it may not support scaling at all. At the same
-time the cropping/composing rectangles may have to be aligned, and both
-the source and the sink may have arbitrary upper and lower size limits.
-Therefore, as usual, drivers are expected to adjust the requested
-parameters and return the actual values selected. An application can
-control the rounding behaviour using
-:ref:`constraint flags <v4l2-selection-flags>`.
-
-
-Configuration of video capture
-==============================
-
-See figure :ref:`sel-targets-capture` for examples of the selection
-targets available for a video capture device. It is recommended to
-configure the cropping targets before to the composing targets.
-
-The range of coordinates of the top left corner, width and height of
-areas that can be sampled is given by the ``V4L2_SEL_TGT_CROP_BOUNDS``
-target. It is recommended for the driver developers to put the top/left
-corner at position ``(0,0)``. The rectangle's coordinates are expressed
-in pixels.
-
-The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by the ``V4L2_SEL_TGT_CROP`` target.
-It uses the same coordinate system as ``V4L2_SEL_TGT_CROP_BOUNDS``. The
-active cropping area must lie completely inside the capture boundaries.
-The driver may further adjust the requested size and/or position
-according to hardware limitations.
-
-Each capture device has a default source rectangle, given by the
-``V4L2_SEL_TGT_CROP_DEFAULT`` target. This rectangle shall cover what the
-driver writer considers the complete picture. Drivers shall set the
-active crop rectangle to the default when the driver is first loaded,
-but not later.
-
-The composing targets refer to a memory buffer. The limits of composing
-coordinates are obtained using ``V4L2_SEL_TGT_COMPOSE_BOUNDS``. All
-coordinates are expressed in pixels. The rectangle's top/left corner
-must be located at position ``(0,0)``. The width and height are equal to
-the image size set by :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
-
-The part of a buffer into which the image is inserted by the hardware is
-controlled by the ``V4L2_SEL_TGT_COMPOSE`` target. The rectangle's
-coordinates are also expressed in the same coordinate system as the
-bounds rectangle. The composing rectangle must lie completely inside
-bounds rectangle. The driver must adjust the composing rectangle to fit
-to the bounding limits. Moreover, the driver can perform other
-adjustments according to hardware limitations. The application can
-control rounding behaviour using
-:ref:`constraint flags <v4l2-selection-flags>`.
-
-For capture devices the default composing rectangle is queried using
-``V4L2_SEL_TGT_COMPOSE_DEFAULT``. It is usually equal to the bounding
-rectangle.
-
-The part of a buffer that is modified by the hardware is given by
-``V4L2_SEL_TGT_COMPOSE_PADDED``. It contains all pixels defined using
-``V4L2_SEL_TGT_COMPOSE`` plus all padding data modified by hardware
-during insertion process. All pixels outside this rectangle *must not*
-be changed by the hardware. The content of pixels that lie inside the
-padded area but outside active area is undefined. The application can
-use the padded and active rectangles to detect where the rubbish pixels
-are located and remove them if needed.
-
-
-Configuration of video output
-=============================
-
-For output devices targets and ioctls are used similarly to the video
-capture case. The *composing* rectangle refers to the insertion of an
-image into a video signal. The cropping rectangles refer to a memory
-buffer. It is recommended to configure the composing targets before to
-the cropping targets.
-
-The cropping targets refer to the memory buffer that contains an image
-to be inserted into a video signal or graphical screen. The limits of
-cropping coordinates are obtained using ``V4L2_SEL_TGT_CROP_BOUNDS``.
-All coordinates are expressed in pixels. The top/left corner is always
-point ``(0,0)``. The width and height is equal to the image size
-specified using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
-
-The top left corner, width and height of the source rectangle, that is
-the area from which image date are processed by the hardware, is given
-by the ``V4L2_SEL_TGT_CROP``. Its coordinates are expressed in in the
-same coordinate system as the bounds rectangle. The active cropping area
-must lie completely inside the crop boundaries and the driver may
-further adjust the requested size and/or position according to hardware
-limitations.
-
-For output devices the default cropping rectangle is queried using
-``V4L2_SEL_TGT_CROP_DEFAULT``. It is usually equal to the bounding
-rectangle.
-
-The part of a video signal or graphics display where the image is
-inserted by the hardware is controlled by ``V4L2_SEL_TGT_COMPOSE``
-target. The rectangle's coordinates are expressed in pixels. The
-composing rectangle must lie completely inside the bounds rectangle. The
-driver must adjust the area to fit to the bounding limits. Moreover, the
-driver can perform other adjustments according to hardware limitations.
-
-The device has a default composing rectangle, given by the
-``V4L2_SEL_TGT_COMPOSE_DEFAULT`` target. This rectangle shall cover what
-the driver writer considers the complete picture. It is recommended for
-the driver developers to put the top/left corner at position ``(0,0)``.
-Drivers shall set the active composing rectangle to the default one when
-the driver is first loaded.
-
-The devices may introduce additional content to video signal other than
-an image from memory buffers. It includes borders around an image.
-However, such a padded area is driver-dependent feature not covered by
-this document. Driver developers are encouraged to keep padded rectangle
-equal to active one. The padded target is accessed by the
-``V4L2_SEL_TGT_COMPOSE_PADDED`` identifier. It must contain all pixels
-from the ``V4L2_SEL_TGT_COMPOSE`` target.
-
-
-Scaling control
-===============
-
-An application can detect if scaling is performed by comparing the width
-and the height of rectangles obtained using ``V4L2_SEL_TGT_CROP`` and
-``V4L2_SEL_TGT_COMPOSE`` targets. If these are not equal then the
-scaling is applied. The application can compute the scaling ratios using
-these values.

-Introduction
-************
-
-Some video capture devices can sample a subsection of a picture and
-shrink or enlarge it to an image of arbitrary size. Next, the devices
-can insert the image into larger one. Some video output devices can crop
-part of an input image, scale it up or down and insert it at an
-arbitrary scan line and horizontal offset into a video signal. We call
-these abilities cropping, scaling and composing.
-
-On a video *capture* device the source is a video signal, and the
-cropping target determine the area actually sampled. The sink is an
-image stored in a memory buffer. The composing area specifies which part
-of the buffer is actually written to by the hardware.
-
-On a video *output* device the source is an image in a memory buffer,
-and the cropping target is a part of an image to be shown on a display.
-The sink is the display or the graphics screen. The application may
-select the part of display where the image should be displayed. The size
-and position of such a window is controlled by the compose target.
-
-Rectangles for all cropping and composing targets are defined even if
-the device does supports neither cropping nor composing. Their size and
-position will be fixed in such a case. If the device does not support
-scaling then the cropping and composing rectangles have the same size.

-********************************
-Comparison with old cropping API
-********************************
-
-The selection API was introduced to cope with deficiencies of the
-older :ref:`CROP API <crop>`, that was designed to control simple
-capture devices. Later the cropping API was adopted by video output
-drivers. The ioctls are used to select a part of the display were the
-video signal is inserted. It should be considered as an API abuse
-because the described operation is actually the composing. The
-selection API makes a clear distinction between composing and cropping
-operations by setting the appropriate targets.
-
-The CROP API lacks any support for composing to and cropping from an
-image inside a memory buffer. The application could configure a
-capture device to fill only a part of an image by abusing V4L2
-API. Cropping a smaller image from a larger one is achieved by setting
-the field ``bytesperline`` at struct :c:type:`v4l2_pix_format`.
-Introducing an image offsets could be done by modifying field
-``m_userptr`` at struct :c:type:`v4l2_buffer` before calling
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`. Those operations should be avoided
-because they are not portable (endianness), and do not work for
-macroblock and Bayer formats and mmap buffers.
-
-The selection API deals with configuration of buffer
-cropping/composing in a clear, intuitive and portable way. Next, with
-the selection API the concepts of the padded target and constraints
-flags are introduced. Finally, struct :c:type:`v4l2_crop` and struct
-:c:type:`v4l2_cropcap` have no reserved fields. Therefore there is no
-way to extend their functionality. The new struct
-:c:type:`v4l2_selection` provides a lot of place for future
-extensions.
-
-Driver developers are encouraged to implement only selection API. The
-former cropping API would be simulated using the new one.

-Video Standards
-***************
-
-Video devices typically support one or more different video standards or
-variations of standards. Each video input and output may support another
-set of standards. This set is reported by the ``std`` field of struct
-:c:type:`v4l2_input` and struct
-:c:type:`v4l2_output` returned by the
-:ref:`VIDIOC_ENUMINPUT` and
-:ref:`VIDIOC_ENUMOUTPUT` ioctls, respectively.
-
-V4L2 defines one bit for each analog video standard currently in use
-worldwide, and sets aside bits for driver defined standards, e. g.
-hybrid standards to watch NTSC video tapes on PAL TVs and vice versa.
-Applications can use the predefined bits to select a particular
-standard, although presenting the user a menu of supported standards is
-preferred. To enumerate and query the attributes of the supported
-standards applications use the :ref:`VIDIOC_ENUMSTD`
-ioctl.
-
-Many of the defined standards are actually just variations of a few
-major standards. The hardware may in fact not distinguish between them,
-or do so internal and switch automatically. Therefore enumerated
-standards also contain sets of one or more standard bits.
-
-Assume a hypothetic tuner capable of demodulating B/PAL, G/PAL and I/PAL
-signals. The first enumerated standard is a set of B and G/PAL, switched
-automatically depending on the selected radio frequency in UHF or VHF
-band. Enumeration gives a "PAL-B/G" or "PAL-I" choice. Similar a
-Composite input may collapse standards, enumerating "PAL-B/G/H/I",
-"NTSC-M" and "SECAM-D/K". [#f1]_
-
-To query and select the standard used by the current video input or
-output applications call the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
-:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` ioctl, respectively. The
-*received* standard can be sensed with the
-:ref:`VIDIOC_QUERYSTD` ioctl.
-
-.. note::
-
-   The parameter of all these ioctls is a pointer to a
-   :ref:`v4l2_std_id <v4l2-std-id>` type (a standard set), *not* an
-   index into the standard enumeration. Drivers must implement all video
-   standard ioctls when the device has one or more video inputs or outputs.
-
-Special rules apply to devices such as USB cameras where the notion of
-video standards makes little sense. More generally for any capture or
-output device which is:
-
--  incapable of capturing fields or frames at the nominal rate of the
-   video standard, or
-
--  that does not support the video standard formats at all.
-
-Here the driver shall set the ``std`` field of struct
-:c:type:`v4l2_input` and struct
-:c:type:`v4l2_output` to zero and the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>`,
-:ref:`VIDIOC_S_STD <VIDIOC_G_STD>`, :ref:`VIDIOC_QUERYSTD` and :ref:`VIDIOC_ENUMSTD` ioctls
-shall return the ``ENOTTY`` error code or the ``EINVAL`` error code.
-
-Applications can make use of the :ref:`input-capabilities` and
-:ref:`output-capabilities` flags to determine whether the video
-standard ioctls can be used with the given input or output.

-Streaming Parameters
-********************
-
-Streaming parameters are intended to optimize the video capture process
-as well as I/O. Presently applications can request a high quality
-capture mode with the :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl.
-
-The current video standard determines a nominal number of frames per
-second. If less than this number of frames is to be captured or output,
-applications can request frame skipping or duplicating on the driver
-side. This is especially useful when using the
-:ref:`read() <func-read>` or :ref:`write() <func-write>`, which are
-not augmented by timestamps or sequence counters, and to avoid
-unnecessary data copying.
-
-Finally these ioctls can be used to determine the number of buffers used
-internally by a driver in read/write mode. For implications see the
-section discussing the :ref:`read() <func-read>` function.
-
-To get and set the streaming parameters applications call the
-:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
-:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take
-a pointer to a struct :c:type:`v4l2_streamparm`, which
-contains a union holding separate parameters for input and output
-devices.
-
-These ioctls are optional, drivers need not implement them. If so, they
-return the ``EINVAL`` error code.

-Media Bus Pixel Codes
----------------------
-
-The media bus pixel codes describe image formats as flowing over
-physical buses (both between separate physical components and inside
-SoC devices). This should not be confused with the V4L2 pixel formats
-that describe, using four character codes, image formats as stored in
-memory.
-
-While there is a relationship between image formats on buses and image
-formats in memory (a raw Bayer image won't be magically converted to
-JPEG just by storing it to memory), there is no one-to-one
-correspondence between them.
-
-The media bus pixel codes document parallel formats. Should the pixel data be
-transported over a serial bus, the media bus pixel code that describes a
-parallel format that transfers a sample on a single clock cycle is used. For
-instance, both MEDIA_BUS_FMT_BGR888_1X24 and MEDIA_BUS_FMT_BGR888_3X8 are used
-on parallel busses for transferring an 8 bits per sample BGR data, whereas on
-serial busses the data in this format is only referred to using
-MEDIA_BUS_FMT_BGR888_1X24. This is because there is effectively only a single
-way to transport that format on the serial busses.
-
-Packed RGB Formats
-^^^^^^^^^^^^^^^^^^
-
-Those formats transfer pixel data as red, green and blue components. The
-format code is made of the following information.
-
--  The red, green and blue components order code, as encoded in a pixel
-   sample. Possible values are RGB and BGR.
-
--  The number of bits per component, for each component. The values can
-   be different for all components. Common values are 555 and 565.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. Common values are
-   1 and 2.
-
--  The bus width.
-
--  For formats where the total number of bits per pixel is smaller than
-   the number of bus samples per pixel times the bus width, a padding
-   value stating if the bytes are padded in their most high order bits
-   (PADHI) or low order bits (PADLO). A "C" prefix is used for
-   component-wise padding in the most high order bits (CPADHI) or low
-   order bits (CPADLO) of each separate component.
-
--  For formats where the number of bus samples per pixel is larger than
-   1, an endianness value stating if the pixel is transferred MSB first
-   (BE) or LSB first (LE).
-
-For instance, a format where pixels are encoded as 5-bits red, 5-bits
-green and 5-bit blue values padded on the high bit, transferred as 2
-8-bit samples per pixel with the most significant bits (padding, red and
-half of the green value) transferred first will be named
-``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``.
-
-The following tables list existing packed RGB formats.
-
-.. HACK: ideally, we would be using adjustbox here. However, Sphinx
-.. is a very bad behaviored guy: if the table has more than 30 cols,
-.. it switches to long table, and there's no way to override it.

-On LVDS buses, usually each sample is transferred serialized in seven
-time slots per pixel clock, on three (18-bit) or four (24-bit)
-differential data pairs at the same time. The remaining bits are used
-for control signals as defined by SPWG/PSWG/VESA or JEIDA standards. The
-24-bit RGB format serialized in seven time slots on four lanes using
-JEIDA defined bit mapping will be named
-``MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA``, for example.

-Bayer Formats
-^^^^^^^^^^^^^
-
-Those formats transfer pixel data as red, green and blue components. The
-format code is made of the following information.
-
--  The red, green and blue components order code, as encoded in a pixel
-   sample. The possible values are shown in :ref:`bayer-patterns`.
-
--  The number of bits per pixel component. All components are
-   transferred on the same number of bits. Common values are 8, 10 and
-   12.
-
--  The compression (optional). If the pixel components are ALAW- or
-   DPCM-compressed, a mention of the compression scheme and the number
-   of bits per compressed pixel component.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. Common values are
-   1 and 2.
-
--  The bus width.
-
--  For formats where the total number of bits per pixel is smaller than
-   the number of bus samples per pixel times the bus width, a padding
-   value stating if the bytes are padded in their most high order bits
-   (PADHI) or low order bits (PADLO).
-
--  For formats where the number of bus samples per pixel is larger than
-   1, an endianness value stating if the pixel is transferred MSB first
-   (BE) or LSB first (LE).
-
-For instance, a format with uncompressed 10-bit Bayer components
-arranged in a red, green, green, blue pattern transferred as 2 8-bit
-samples per pixel with the least significant bits transferred first will
-be named ``MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE``.

-The following table lists existing packed Bayer formats. The data
-organization is given as an example for the first pixel only.

-
-.. HACK: ideally, we would be using adjustbox here. However, Sphinx
-.. is a very bad behaviored guy: if the table has more than 30 cols,
-.. it switches to long table, and there's no way to override it.

-Packed YUV Formats
-^^^^^^^^^^^^^^^^^^
-
-Those data formats transfer pixel data as (possibly downsampled) Y, U
-and V components. Some formats include dummy bits in some of their
-samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma)
-formats. One cannot rely on the values of these dummy bits as those are
-undefined.
-
-The format code is made of the following information.
-
--  The Y, U and V components order code, as transferred on the bus.
-   Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
-   dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC
-   formats.
-
--  The number of bits per pixel component. All components are
-   transferred on the same number of bits. Common values are 8, 10 and
-   12.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. Common values are
-   0.5 (encoded as 0_5; in this case two pixels are transferred per bus
-   sample), 1, 1.5 (encoded as 1_5) and 2.
-
--  The bus width. When the bus width is larger than the number of bits
-   per pixel component, several components are packed in a single bus
-   sample. The components are ordered as specified by the order code,
-   with components on the left of the code transferred in the high order
-   bits. Common values are 8 and 16.
-
-For instance, a format where pixels are encoded as 8-bit YUV values
-downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in
-the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``.
-
-:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and
-describes the organization of each pixel data in each sample. When a
-format pattern is split across multiple samples each of the samples in
-the pattern is described.
-
-The role of each bit transferred over the bus is identified by one of
-the following codes.
-
--  y\ :sub:`x` for luma component bit number x
-
--  u\ :sub:`x` for blue chroma component bit number x
-
--  v\ :sub:`x` for red chroma component bit number x
-
--  a\ :sub:`x` for alpha component bit number x
-
-- for non-available bits (for positions higher than the bus width)
-
--  d for dummy bits

-HSV/HSL Formats
-^^^^^^^^^^^^^^^
-
-Those formats transfer pixel data as RGB values in a
-cylindrical-coordinate system using Hue-Saturation-Value or
-Hue-Saturation-Lightness components. The format code is made of the
-following information.
-
--  The hue, saturation, value or lightness and optional alpha components
-   order code, as encoded in a pixel sample. The only currently
-   supported value is AHSV.
-
--  The number of bits per component, for each component. The values can
-   be different for all components. The only currently supported value
-   is 8888.
-
--  The number of bus samples per pixel. Pixels that are wider than the
-   bus width must be transferred in multiple samples. The only currently
-   supported value is 1.
-
--  The bus width.
-
--  For formats where the total number of bits per pixel is smaller than
-   the number of bus samples per pixel times the bus width, a padding
-   value stating if the bytes are padded in their most high order bits
-   (PADHI) or low order bits (PADLO).
-
--  For formats where the number of bus samples per pixel is larger than
-   1, an endianness value stating if the pixel is transferred MSB first
-   (BE) or LSB first (LE).

-JPEG Compressed Formats
-^^^^^^^^^^^^^^^^^^^^^^^
-
-Those data formats consist of an ordered sequence of 8-bit bytes
-obtained from JPEG compression process. Additionally to the ``_JPEG``
-postfix the format code is made of the following information.
-
--  The number of bus samples per entropy encoded byte.
-
--  The bus width.
-
-For instance, for a JPEG baseline process and an 8-bit bus width the
-format will be named ``MEDIA_BUS_FMT_JPEG_1X8``.
-
-The following table lists existing JPEG compressed formats.

-Tuners
-======
-
-Video input devices can have one or more tuners demodulating a RF
-signal. Each tuner is associated with one or more video inputs,
-depending on the number of RF connectors on the tuner. The ``type``
-field of the respective struct :c:type:`v4l2_input`
-returned by the :ref:`VIDIOC_ENUMINPUT` ioctl is
-set to ``V4L2_INPUT_TYPE_TUNER`` and its ``tuner`` field contains the
-index number of the tuner.
-
-Radio input devices have exactly one tuner with index zero, no video
-inputs.
-
-To query and change tuner properties applications use the
-:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
-:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` ioctls, respectively. The
-struct :c:type:`v4l2_tuner` returned by :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>`
-also contains signal status information applicable when the tuner of the
-current video or radio input is queried.
-
-.. note::
-
-   :ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` does not switch the
-   current tuner, when there is more than one. The tuner is solely
-   determined by the current video input. Drivers must support both ioctls
-   and set the ``V4L2_CAP_TUNER`` flag in the struct :c:type:`v4l2_capability`
-   returned by the :ref:`VIDIOC_QUERYCAP` ioctl when the
-   device has one or more tuners.

-Video output devices can have one or more modulators, that modulate a
-video signal for radiation or connection to the antenna input of a TV
-set or video recorder. Each modulator is associated with one or more
-video outputs, depending on the number of RF connectors on the
-modulator. The ``type`` field of the respective struct
-:c:type:`v4l2_output` returned by the
-:ref:`VIDIOC_ENUMOUTPUT` ioctl is set to
-``V4L2_OUTPUT_TYPE_MODULATOR`` and its ``modulator`` field contains the
-index number of the modulator.
-
-Radio output devices have exactly one modulator with index zero, no
-video outputs.
-
-A video or radio device cannot support both a tuner and a modulator. Two
-separate device nodes will have to be used for such hardware, one that
-supports the tuner functionality and one that supports the modulator
-functionality. The reason is a limitation with the
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl where you
-cannot specify whether the frequency is for a tuner or a modulator.
-
-To query and change modulator properties applications use the
-:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` and
-:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Note that
-:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` does not switch the current modulator, when there
-is more than one at all. The modulator is solely determined by the
-current video output. Drivers must support both ioctls and set the
-``V4L2_CAP_MODULATOR`` flag in the struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl when the device has
-one or more modulators.
-
-
-Radio Frequency
-===============
-
-To get and set the tuner or modulator radio frequency applications use
-the :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl which both take
-a pointer to a struct :c:type:`v4l2_frequency`. These
-ioctls are used for TV and radio devices alike. Drivers must support
-both ioctls when the tuner or modulator ioctls are supported, or when
-the device is a radio device.

-*****************************
-Streaming I/O (User Pointers)
-*****************************
-
-Input and output devices support this I/O method when the
-``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
-:c:type:`v4l2_capability` returned by the
-:ref:`VIDIOC_QUERYCAP` ioctl is set. If the
-particular user pointer method (not only memory mapping) is supported
-must be determined by calling the :ref:`VIDIOC_REQBUFS` ioctl
-with the memory type set to ``V4L2_MEMORY_USERPTR``.
-
-This I/O method combines advantages of the read/write and memory mapping
-methods. Buffers (planes) are allocated by the application itself, and
-can reside for example in virtual or shared memory. Only pointers to
-data are exchanged, these pointers and meta-information are passed in
-struct :c:type:`v4l2_buffer` (or in struct
-:c:type:`v4l2_plane` in the multi-planar API case). The
-driver must be switched into user pointer I/O mode by calling the
-:ref:`VIDIOC_REQBUFS` with the desired buffer type.
-No buffers (planes) are allocated beforehand, consequently they are not
-indexed and cannot be queried like mapped buffers with the
-:ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>` ioctl.
-
-Example: Initiating streaming I/O with user pointers
-====================================================
-
-.. code-block:: c
-
-    struct v4l2_requestbuffers reqbuf;
-
-    memset (&reqbuf, 0, sizeof (reqbuf));
-    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
-    reqbuf.memory = V4L2_MEMORY_USERPTR;
-
-    if (ioctl (fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
-	if (errno == EINVAL)
-	    printf ("Video capturing or user pointer streaming is not supported\\n");
-	else
-	    perror ("VIDIOC_REQBUFS");
-
-	exit (EXIT_FAILURE);
-    }
-
-Buffer (plane) addresses and sizes are passed on the fly with the
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. Although buffers are commonly
-cycled, applications can pass different addresses and sizes at each
-:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call. If required by the hardware the
-driver swaps memory pages within physical memory to create a continuous
-area of memory. This happens transparently to the application in the
-virtual memory subsystem of the kernel. When buffer pages have been
-swapped out to disk they are brought back and finally locked in physical
-memory for DMA. [#f1]_
-
-Filled or displayed buffers are dequeued with the
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
-memory pages at any time between the completion of the DMA and this
-ioctl. The memory is also unlocked when
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
-:ref:`VIDIOC_REQBUFS`, or when the device is closed.
-Applications must take care not to free buffers without dequeuing.
-Firstly, the buffers remain locked for longer, wasting physical memory.
-Secondly the driver will not be notified when the memory is returned to
-the application's free list and subsequently reused for other purposes,
-possibly completing the requested DMA and overwriting valuable data.
-
-For capturing applications it is customary to enqueue a number of empty
-buffers, to start capturing and enter the read loop. Here the
-application waits until a filled buffer can be dequeued, and re-enqueues
-the buffer when the data is no longer needed. Output applications fill
-and enqueue buffers, when enough buffers are stacked up output is
-started. In the write loop, when the application runs out of free
-buffers it must wait until an empty buffer can be dequeued and reused.
-Two methods exist to suspend execution of the application until one or
-more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
-<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
-``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
-error code when no buffer is available. The :ref:`select()
-<func-select>` or :ref:`poll() <func-poll>` function are always
-available.
-
-To start and stop capturing or output applications call the
-:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctl.
-
-.. note::
-
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
-   both queues and unlocks all buffers as a side effect. Since there is no
-   notion of doing anything "now" on a multitasking system, if an
-   application needs to synchronize with another event it should examine
-   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
-   outputted buffers.
-
-Drivers implementing user pointer I/O must support the
-:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
-:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the
-:ref:`select() <func-select>` and :ref:`poll() <func-poll>` function. [#f2]_
-
-.. [#f1]
-   We expect that frequently used buffers are typically not swapped out.
-   Anyway, the process of swapping, locking or generating scatter-gather
-   lists may be time consuming. The delay can be masked by the depth of
-   the incoming buffer queue, and perhaps by maintaining caches assuming
-   a buffer will be soon enqueued again. On the other hand, to optimize
-   memory usage drivers can limit the number of buffers locked in
-   advance and recycle the most recently used buffers first. Of course,
-   the pages of empty buffers in the incoming queue need not be saved to
-   disk. Output buffers must be saved on the incoming and outgoing queue
-   because an application may share them with other processes.
-
-.. [#f2]
-   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
-   the same, and :ref:`select() <func-select>` is too important to be optional.
-   The rest should be evident.

-Video Inputs and Outputs
-************************
-
-Video inputs and outputs are physical connectors of a device. These can
-be for example: RF connectors (antenna/cable), CVBS a.k.a. Composite
-Video, S-Video and RGB connectors. Camera sensors are also considered to
-be a video input. Video and VBI capture devices have inputs. Video and
-VBI output devices have outputs, at least one each. Radio devices have
-no video inputs or outputs.
-
-To learn about the number and attributes of the available inputs and
-outputs applications can enumerate them with the
-:ref:`VIDIOC_ENUMINPUT` and
-:ref:`VIDIOC_ENUMOUTPUT` ioctl, respectively. The
-struct :c:type:`v4l2_input` returned by the
-:ref:`VIDIOC_ENUMINPUT` ioctl also contains signal
-status information applicable when the current video input is queried.
-
-The :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
-:ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` ioctls return the index of
-the current video input or output. To select a different input or output
-applications call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` and
-:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` ioctls. Drivers must
-implement all the input ioctls when the device has one or more inputs,
-all the output ioctls when the device has one or more outputs.

-    :name: VIDIOC_CREATE_BUFS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_create_buffers`.
-
-
-Description
-===========
-
-This ioctl is used to create buffers for :ref:`memory mapped <mmap>`
-or :ref:`user pointer <userp>` or :ref:`DMA buffer <dmabuf>` I/O. It
-can be used as an alternative or in addition to the
-:ref:`VIDIOC_REQBUFS` ioctl, when a tighter control
-over buffers is required. This ioctl can be called multiple times to
-create buffers of different sizes.
-
-To allocate the device buffers applications must initialize the relevant
-fields of the struct :c:type:`v4l2_create_buffers` structure. The
-``count`` field must be set to the number of requested buffers, the
-``memory`` field specifies the requested I/O method and the ``reserved``
-array must be zeroed.
-
-The ``format`` field specifies the image format that the buffers must be
-able to handle. The application has to fill in this struct
-:c:type:`v4l2_format`. Usually this will be done using the
-:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` or
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctls to ensure that the
-requested format is supported by the driver. Based on the format's
-``type`` field the requested buffer size (for single-planar) or plane
-sizes (for multi-planar formats) will be used for the allocated buffers.
-The driver may return an error if the size(s) are not supported by the
-hardware (usually because they are too small).
-
-The buffers created by this ioctl will have as minimum size the size
-defined by the ``format.pix.sizeimage`` field (or the corresponding
-fields for other format types). Usually if the ``format.pix.sizeimage``
-field is less than the minimum required for the given format, then an
-error will be returned since drivers will typically not allow this. If
-it is larger, then the value will be used as-is. In other words, the
-driver may reject the requested size, but if it is accepted the driver
-will use it unchanged.
-
-When the ioctl is called with a pointer to this structure the driver
-will attempt to allocate up to the requested number of buffers and store
-the actual number allocated and the starting index in the ``count`` and
-the ``index`` fields respectively. On return ``count`` can be smaller
-than the number requested.

-	created buffers, and it will check the validity of ``memory`` and
-	``format.type``. If those are invalid -1 is returned and errno is

-	0. It will never set errno to ``EBUSY`` error code in this particular

-      - Filled in by the application, preserved by the driver.
-    * - __u32
-      - ``capabilities``
-      - Set by the driver. If 0, then the driver doesn't support
-        capabilities. In that case all you know is that the driver is
-	guaranteed to support ``V4L2_MEMORY_MMAP`` and *might* support
-	other :c:type:`v4l2_memory` types. It will not support any others
-	capabilities. See :ref:`here <v4l2-buf-capabilities>` for a list of the
-	capabilities.
-
-	If you want to just query the capabilities without making any
-	other changes, then set ``count`` to 0, ``memory`` to
-	``V4L2_MEMORY_MMAP`` and ``format.type`` to the buffer type.
-    * - __u32
-      - ``reserved``\ [7]
-      - A place holder for future extensions. Drivers and applications
-	must set the array to zero.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-ENOMEM
-    No memory to allocate buffers for :ref:`memory mapped <mmap>` I/O.
-
-EINVAL
-    The buffer type (``format.type`` field), requested I/O method
-    (``memory``) or format (``format`` field) is not valid.

-
-``argp``
-    Pointer to struct :c:type:`v4l2_cropcap`.
-
-
-Description
-===========
-
-Applications use this function to query the cropping limits, the pixel
-aspect of images and to calculate scale factors. They set the ``type``
-field of a v4l2_cropcap structure to the respective buffer (stream)
-type and call the :ref:`VIDIOC_CROPCAP` ioctl with a pointer to this
-structure. Drivers fill the rest of the structure. The results are
-constant except when switching the video standard. Remember this switch
-can occur implicit when switching the video input or output.
-
-This ioctl must be implemented for video capture or output devices that
-support cropping and/or scaling and/or have non-square pixels, and for
-overlay devices.

-    * - __u32
-      - ``type``
-      - Type of the data stream, set by the application. Only these types
-	are valid here: ``V4L2_BUF_TYPE_VIDEO_CAPTURE``, ``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``,
-	``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE`` and

-    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
-      - ``bounds``
-      - Defines the window within capturing or output is possible, this
-	may exclude for example the horizontal and vertical blanking
-	areas. The cropping rectangle cannot exceed these limits. Width
-	and height are defined in pixels, the driver writer is free to
-	choose origin and units of the coordinate system in the analog
-	domain.
-    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
-      - ``defrect``
-      - Default cropping rectangle, it shall cover the "whole picture".
-	Assuming pixel aspect 1/1 this could be for example a 640 × 480
-	rectangle for NTSC, a 768 × 576 rectangle for PAL and SECAM
-	centered over the active picture area. The same co-ordinate system
-	as for ``bounds`` is used.
-    * - struct :c:type:`v4l2_fract`
-      - ``pixelaspect``
-      - This is the pixel aspect (y / x) when no scaling is applied, the
-	ratio of the actual sampling frequency and the frequency required
-	to get square pixels.
-
-	When cropping coordinates refer to square pixels, the driver sets
-	``pixelaspect`` to 1/1. Other common values are 54/59 for PAL and
-	SECAM, 11/10 for NTSC sampled according to [:ref:`itu601`].
-
-.. note::
-   Unfortunately in the case of multiplanar buffer types
-   (``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``)
-   this API was messed up with regards to how the :c:type:`v4l2_cropcap` ``type`` field
-   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
-   other drivers only accepted a non-multiplanar buffer type (i.e. without the
-   ``_MPLANE`` at the end).
-
-   Starting with kernel 4.13 both variations are allowed.

-    :name: VIDIOC_DBG_G_CHIP_INFO
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_dbg_chip_info`.
-
-
-Description
-===========
-
-.. note::
-
-    This is an :ref:`experimental` interface and may
-    change in the future.
-
-For driver debugging purposes this ioctl allows test applications to
-query the driver about the chips present on the TV card. Regular
-applications must not use it. When you found a chip specific bug, please
-contact the linux-media mailing list
-(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__)
-so it can be fixed.
-
-Additionally the Linux kernel must be compiled with the
-``CONFIG_VIDEO_ADV_DEBUG`` option to enable this ioctl.
-
-To query the driver applications must initialize the ``match.type`` and
-``match.addr`` or ``match.name`` fields of a struct
-:c:type:`v4l2_dbg_chip_info` and call
-:ref:`VIDIOC_DBG_G_CHIP_INFO` with a pointer to this structure. On success
-the driver stores information about the selected chip in the ``name``
-and ``flags`` fields.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
-selects the nth bridge 'chip' on the TV card. You can enumerate all
-chips by starting at zero and incrementing ``match.addr`` by one until
-:ref:`VIDIOC_DBG_G_CHIP_INFO` fails with an ``EINVAL`` error code. The number
-zero always selects the bridge chip itself, e. g. the chip connected to
-the PCI or USB bus. Non-zero numbers identify specific parts of the
-bridge chip such as an AC97 register block.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
-selects the nth sub-device. This allows you to enumerate over all
-sub-devices.
-
-On success, the ``name`` field will contain a chip name and the
-``flags`` field will contain ``V4L2_CHIP_FL_READABLE`` if the driver
-supports reading registers from the device or ``V4L2_CHIP_FL_WRITABLE``
-if the driver supports writing registers to the device.
-
-We recommended the v4l2-dbg utility over calling this ioctl directly. It
-is available from the LinuxTV v4l-dvb repository; see
-`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access
-instructions.

-

-

-    Pointer to struct :c:type:`v4l2_dbg_register`.
-
-
-Description
-===========
-
-.. note::
-
-    This is an :ref:`experimental` interface and may
-    change in the future.
-
-For driver debugging purposes these ioctls allow test applications to
-access hardware registers directly. Regular applications must not use
-them.
-
-Since writing or even reading registers can jeopardize the system
-security, its stability and damage the hardware, both ioctls require
-superuser privileges. Additionally the Linux kernel must be compiled
-with the ``CONFIG_VIDEO_ADV_DEBUG`` option to enable these ioctls.
-
-To write a register applications must initialize all fields of a struct
-:c:type:`v4l2_dbg_register` except for ``size`` and
-call ``VIDIOC_DBG_S_REGISTER`` with a pointer to this structure. The
-``match.type`` and ``match.addr`` or ``match.name`` fields select a chip
-on the TV card, the ``reg`` field specifies a register number and the
-``val`` field the value to be written into the register.
-
-To read a register applications must initialize the ``match.type``,
-``match.addr`` or ``match.name`` and ``reg`` fields, and call
-``VIDIOC_DBG_G_REGISTER`` with a pointer to this structure. On success
-the driver stores the register value in the ``val`` field and the size
-(in bytes) of the value in ``size``.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
-selects the nth non-sub-device chip on the TV card. The number zero
-always selects the host chip, e. g. the chip connected to the PCI or USB
-bus. You can find out which chips are present with the
-:ref:`VIDIOC_DBG_G_CHIP_INFO` ioctl.
-
-When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
-selects the nth sub-device.
-
-These ioctls are optional, not all drivers may support them. However
-when a driver supports these ioctls it must also support
-:ref:`VIDIOC_DBG_G_CHIP_INFO`. Conversely
-it may support ``VIDIOC_DBG_G_CHIP_INFO`` but not these ioctls.
-
-``VIDIOC_DBG_G_REGISTER`` and ``VIDIOC_DBG_S_REGISTER`` were introduced
-in Linux 2.6.21, but their API was changed to the one described here in
-kernel 2.6.29.
-
-We recommended the v4l2-dbg utility over calling these ioctls directly.

-Description
-===========
-
-These ioctls control an audio/video (usually MPEG-) decoder.
-``VIDIOC_DECODER_CMD`` sends a command to the decoder,
-``VIDIOC_TRY_DECODER_CMD`` can be used to try a command without actually
-executing it. To send a command applications must initialize all fields
-of a struct :c:type:`v4l2_decoder_cmd` and call
-``VIDIOC_DECODER_CMD`` or ``VIDIOC_TRY_DECODER_CMD`` with a pointer to
-this structure.
-
-The ``cmd`` field must contain the command code. Some commands use the
-``flags`` field for additional information.
-
-A :ref:`write() <func-write>` or :ref:`VIDIOC_STREAMON`
-call sends an implicit START command to the decoder if it has not been
-started yet. Applies to both queues of mem2mem decoders.
-
-A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
-call of a streaming file descriptor sends an implicit immediate STOP
-command to the decoder, and all buffered data is discarded. Applies to both
-queues of mem2mem decoders.
-
-In principle, these ioctls are optional, not all drivers may support them. They were
-introduced in Linux 3.3. They are, however, mandatory for stateful mem2mem decoders
-(as further documented in :ref:`decoder`).

-    * -
-      - __s32
-      - ``speed``
-      - Playback speed and direction. The playback speed is defined as
-	``speed``/1000 of the normal speed. So 1000 is normal playback.
-	Negative numbers denote reverse playback, so -1000 does reverse
-	playback at normal speed. Speeds -1, 0 and 1 have special
-	meanings: speed 0 is shorthand for 1000 (normal playback). A speed
-	of 1 steps just one frame forward, a speed of -1 steps just one
-	frame back.
-    * -
-      - __u32
-      - ``format``
-      - Format restrictions. This field is set by the driver, not the
-	application. Possible values are ``V4L2_DEC_START_FMT_NONE`` if
-	there are no format restrictions or ``V4L2_DEC_START_FMT_GOP`` if
-	the decoder operates on full GOPs (*Group Of Pictures*). This is
-	usually the case for reverse playback: the decoder needs full
-	GOPs, which it can then play in reverse order. So to implement
-	reverse playback the application must feed the decoder the last
-	GOP in the video file, then the GOP before that, etc. etc.

-
-    * - ``V4L2_DEC_CMD_START``
-      - 0
-      - Start the decoder. When the decoder is already running or paused,
-	this command will just change the playback speed. That means that
-	calling ``V4L2_DEC_CMD_START`` when the decoder was paused will
-	*not* resume the decoder. You have to explicitly call
-	``V4L2_DEC_CMD_RESUME`` for that. This command has one flag:
-	``V4L2_DEC_CMD_START_MUTE_AUDIO``. If set, then audio will be
-	muted when playing back at a non-standard speed.
-
-	For a device implementing the :ref:`decoder`, once the drain sequence
-	is initiated with the ``V4L2_DEC_CMD_STOP`` command, it must be driven
-	to completion before this command can be invoked.  Any attempt to
-	invoke the command while the drain sequence is in progress will trigger
-	an ``EBUSY`` error code.  The command may be also used to restart the
-	decoder in case of an implicit stop initiated by the decoder itself,
-	without the ``V4L2_DEC_CMD_STOP`` being called explicitly. See
-	:ref:`decoder` for more details.
-    * - ``V4L2_DEC_CMD_STOP``
-      - 1
-      - Stop the decoder. When the decoder is already stopped, this
-	command does nothing. This command has two flags: if
-	``V4L2_DEC_CMD_STOP_TO_BLACK`` is set, then the decoder will set
-	the picture to black after it stopped decoding. Otherwise the last
-	image will repeat. If
-	``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops
-	immediately (ignoring the ``pts`` value), otherwise it will keep
-	decoding until timestamp >= pts or until the last of the pending
-	data from its internal buffers was decoded.
-
-	For a device implementing the :ref:`decoder`, the command will initiate
-	the drain sequence as documented in :ref:`decoder`.  No flags or other
-	arguments are accepted in this case. Any attempt to invoke the command
-	again before the sequence completes will trigger an ``EBUSY`` error
-	code.
-    * - ``V4L2_DEC_CMD_PAUSE``
-      - 2
-      - Pause the decoder. When the decoder has not been started yet, the
-	driver will return an ``EPERM`` error code. When the decoder is
-	already paused, this command does nothing. This command has one
-	flag: if ``V4L2_DEC_CMD_PAUSE_TO_BLACK`` is set, then set the
-	decoder output to black when paused.
-    * - ``V4L2_DEC_CMD_RESUME``
-      - 3
-      - Resume decoding after a PAUSE command. When the decoder has not
-	been started yet, the driver will return an ``EPERM`` error code. When
-	the decoder is already running, this command does nothing. No
-	flags are defined for this command.
-    * - ``V4L2_DEC_CMD_FLUSH``
-      - 4
-      - Flush any held capture buffers. Only valid for stateless decoders.
-	This command is typically used when the application reached the
-	end of the stream and the last output buffer had the
-	``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag set. This would prevent
-	dequeueing the capture buffer containing the last decoded frame.
-	So this command can be used to explicitly flush that final decoded
-	frame. This command does nothing if there are no held capture buffers.
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the

-    A drain sequence of a device implementing the :ref:`decoder` is still in

-      - 0
-      - All events. V4L2_EVENT_ALL is valid only for
-	VIDIOC_UNSUBSCRIBE_EVENT for unsubscribing all events at once.
-    * - ``V4L2_EVENT_VSYNC``
-      - 1
-      - This event is triggered on the vertical sync. This event has a
-	struct :c:type:`v4l2_event_vsync` associated
-	with it.
-    * - ``V4L2_EVENT_EOS``
-      - 2
-      - This event is triggered when the end of a stream is reached. This
-	is typically used with MPEG decoders to report to the application
-	when the last of the MPEG stream has been decoded.
-    * - ``V4L2_EVENT_CTRL``
-      - 3
-      - This event requires that the ``id`` matches the control ID from
-	which you want to receive events. This event is triggered if the
-	control's value changes, if a button control is pressed or if the
-	control's flags change. This event has a struct
-	:c:type:`v4l2_event_ctrl` associated with it.
-	This struct contains much of the same information as struct
-	:ref:`v4l2_queryctrl <v4l2-queryctrl>` and struct
-	:c:type:`v4l2_control`.
-
-	If the event is generated due to a call to
-	:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` or
-	:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then the
-	event will *not* be sent to the file handle that called the ioctl
-	function. This prevents nasty feedback loops. If you *do* want to
-	get the event, then set the ``V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK``
-	flag.
-
-	This event type will ensure that no information is lost when more
-	events are raised than there is room internally. In that case the
-	struct :c:type:`v4l2_event_ctrl` of the
-	second-oldest event is kept, but the ``changes`` field of the
-	second-oldest event is ORed with the ``changes`` field of the
-	oldest event.
-    * - ``V4L2_EVENT_FRAME_SYNC``
-      - 4
-      - Triggered immediately when the reception of a frame has begun.
-	This event has a struct
-	:c:type:`v4l2_event_frame_sync`
-	associated with it.
-
-	If the hardware needs to be stopped in the case of a buffer
-	underrun it might not be able to generate this event. In such
-	cases the ``frame_sequence`` field in struct
-	:c:type:`v4l2_event_frame_sync` will not
-	be incremented. This causes two consecutive frame sequence numbers
-	to have n times frame interval in between them.
-    * - ``V4L2_EVENT_SOURCE_CHANGE``
-      - 5
-      - This event is triggered when a source parameter change is detected
-	during runtime by the video device. It can be a runtime resolution
-	change triggered by a video decoder or the format change happening
-	on an input connector. This event requires that the ``id`` matches
-	the input index (when used with a video device node) or the pad
-	index (when used with a subdevice node) from which you want to
-	receive events.
-
-	This event has a struct
-	:c:type:`v4l2_event_src_change`
-	associated with it. The ``changes`` bitfield denotes what has
-	changed for the subscribed pad. If multiple events occurred before
-	application could dequeue them, then the changes will have the
-	ORed value of all the events generated.
-    * - ``V4L2_EVENT_MOTION_DET``
-      - 6
-      - Triggered whenever the motion detection state for one or more of

-
-Description
-===========
-
-To query the capabilities of the DV receiver/transmitter applications
-initialize the ``pad`` field to 0, zero the reserved array of struct
-:c:type:`v4l2_dv_timings_cap` and call the
-``VIDIOC_DV_TIMINGS_CAP`` ioctl on a video node and the driver will fill
-in the structure.
-
-.. note::
-
-   Drivers may return different values after
-   switching the video input or output.
-
-When implemented by the driver DV capabilities of subdevices can be
-queried by calling the ``VIDIOC_SUBDEV_DV_TIMINGS_CAP`` ioctl directly
-on a subdevice node. The capabilities are specific to inputs (for DV
-receivers) or outputs (for DV transmitters), applications must specify
-the desired pad number in the struct
-:c:type:`v4l2_dv_timings_cap` ``pad`` field and
-zero the ``reserved`` array. Attempts to query capabilities on a pad
-that doesn't support them will return an ``EINVAL`` error code.

-
-Description
-===========
-
-These ioctls control an audio/video (usually MPEG-) encoder.
-``VIDIOC_ENCODER_CMD`` sends a command to the encoder,
-``VIDIOC_TRY_ENCODER_CMD`` can be used to try a command without actually
-executing it.
-
-To send a command applications must initialize all fields of a struct
-:c:type:`v4l2_encoder_cmd` and call
-``VIDIOC_ENCODER_CMD`` or ``VIDIOC_TRY_ENCODER_CMD`` with a pointer to
-this structure.
-
-The ``cmd`` field must contain the command code. The ``flags`` field is
-currently only used by the STOP command and contains one bit: If the
-``V4L2_ENC_CMD_STOP_AT_GOP_END`` flag is set, encoding will continue
-until the end of the current *Group Of Pictures*, otherwise it will stop
-immediately.
-
-A :ref:`read() <func-read>` or :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
-call sends an implicit START command to the encoder if it has not been
-started yet. After a STOP command, :ref:`read() <func-read>` calls will read
-the remaining data buffered by the driver. When the buffer is empty,
-:ref:`read() <func-read>` will return zero and the next :ref:`read() <func-read>`
-call will restart the encoder.
-
-A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
-call of a streaming file descriptor sends an implicit immediate STOP to
-the encoder, and all buffered data is discarded.
-
-These ioctls are optional, not all drivers may support them. They were
-introduced in Linux 2.6.21.

-Description
-===========
-
-While some DV receivers or transmitters support a wide range of timings,
-others support only a limited number of timings. With this ioctl
-applications can enumerate a list of known supported timings. Call
-:ref:`VIDIOC_DV_TIMINGS_CAP` to check if it
-also supports other standards or even custom timings that are not in
-this list.
-
-To query the available timings, applications initialize the ``index``
-field, set the ``pad`` field to 0, zero the reserved array of struct
-:c:type:`v4l2_enum_dv_timings` and call the
-``VIDIOC_ENUM_DV_TIMINGS`` ioctl on a video node with a pointer to this
-structure. Drivers fill the rest of the structure or return an ``EINVAL``
-error code when the index is out of bounds. To enumerate all supported
-DV timings, applications shall begin at index zero, incrementing by one
-until the driver returns ``EINVAL``.
-
-.. note::
-
-   Drivers may enumerate a different set of DV timings after
-   switching the video input or output.
-
-When implemented by the driver DV timings of subdevices can be queried
-by calling the ``VIDIOC_SUBDEV_ENUM_DV_TIMINGS`` ioctl directly on a
-subdevice node. The DV timings are specific to inputs (for DV receivers)
-or outputs (for DV transmitters), applications must specify the desired
-pad number in the struct
-:c:type:`v4l2_enum_dv_timings` ``pad`` field.
-Attempts to enumerate timings on a pad that doesn't support them will
-return an ``EINVAL`` error code.

-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_ENUM_FRAMEINTERVALS, struct v4l2_frmivalenum *argp )
-    :name: VIDIOC_ENUM_FRAMEINTERVALS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_frmivalenum`
-    that contains a pixel format and size and receives a frame interval.
-
-
-Description
-===========
-
-This ioctl allows applications to enumerate all frame intervals that the
-device supports for the given pixel format and frame size.
-
-The supported pixel formats and frame sizes can be obtained by using the
-:ref:`VIDIOC_ENUM_FMT` and
-:ref:`VIDIOC_ENUM_FRAMESIZES` functions.
-
-The return value and the content of the ``v4l2_frmivalenum.type`` field
-depend on the type of frame intervals the device supports. Here are the
-semantics of the function for the different cases:
-
--  **Discrete:** The function returns success if the given index value
-   (zero-based) is valid. The application should increase the index by
-   one for each call until ``EINVAL`` is returned. The
-   `v4l2_frmivalenum.type` field is set to
-   `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the union only
-   the `discrete` member is valid.
-
--  **Step-wise:** The function returns success if the given index value
-   is zero and ``EINVAL`` for any other index value. The
-   ``v4l2_frmivalenum.type`` field is set to
-   ``V4L2_FRMIVAL_TYPE_STEPWISE`` by the driver. Of the union only the
-   ``stepwise`` member is valid.
-
--  **Continuous:** This is a special case of the step-wise type above.
-   The function returns success if the given index value is zero and
-   ``EINVAL`` for any other index value. The ``v4l2_frmivalenum.type``
-   field is set to ``V4L2_FRMIVAL_TYPE_CONTINUOUS`` by the driver. Of
-   the union only the ``stepwise`` member is valid and the ``step``
-   value is set to 1.
-
-When the application calls the function with index zero, it must check
-the ``type`` field to determine the type of frame interval enumeration
-the device supports. Only for the ``V4L2_FRMIVAL_TYPE_DISCRETE`` type
-does it make sense to increase the index value to receive more frame
-intervals.
-
-.. note::
-
-   The order in which the frame intervals are returned has no
-   special meaning. In particular does it not say anything about potential
-   default frame intervals.
-
-Applications can assume that the enumeration data does not change
-without any interaction from the application itself. This means that the
-enumeration data is consistent if the application does not perform any
-other ioctl calls while it runs the frame interval enumeration.
-
-.. note::
-
-   **Frame intervals and frame rates:** The V4L2 API uses frame
-   intervals instead of frame rates. Given the frame interval the frame
-   rate can be computed as follows:
-
-   ::
-
-       frame_rate = 1 / frame_interval

-   ``V4L2_FRMSIZE_TYPE_DISCRETE`` by the driver. Of the union only the
-   ``discrete`` member is valid.
-
--  **Step-wise:** The function returns success if the given index value
-   is zero and ``EINVAL`` for any other index value. The
-   ``v4l2_frmsizeenum.type`` field is set to
-   ``V4L2_FRMSIZE_TYPE_STEPWISE`` by the driver. Of the union only the
-   ``stepwise`` member is valid.
-
--  **Continuous:** This is a special case of the step-wise type above.
-   The function returns success if the given index value is zero and
-   ``EINVAL`` for any other index value. The ``v4l2_frmsizeenum.type``
-   field is set to ``V4L2_FRMSIZE_TYPE_CONTINUOUS`` by the driver. Of
-   the union only the ``stepwise`` member is valid and the
-   ``step_width`` and ``step_height`` values are set to 1.
-
-When the application calls the function with index zero, it must check
-the ``type`` field to determine the type of frame size enumeration the
-device supports. Only for the ``V4L2_FRMSIZE_TYPE_DISCRETE`` type does
-it make sense to increase the index value to receive more frame sizes.
-
-.. note::
-
-   The order in which the frame sizes are returned has no special
-   meaning. In particular does it not say anything about potential default
-   format sizes.
-
-Applications can assume that the enumeration data does not change
-without any interaction from the application itself. This means that the
-enumeration data is consistent if the application does not perform any
-other ioctl calls while it runs the frame size enumeration.
-
-
-Structs
-=======
-
-In the structs below, *IN* denotes a value that has to be filled in by
-the application, *OUT* denotes values that the driver fills in. The
-application should zero out all members except for the *IN* fields.

-Description
-===========
-
-Enumerates the frequency bands that a tuner or modulator supports. To do
-this applications initialize the ``tuner``, ``type`` and ``index``
-fields, and zero out the ``reserved`` array of a struct
-:c:type:`v4l2_frequency_band` and call the
-:ref:`VIDIOC_ENUM_FREQ_BANDS` ioctl with a pointer to this structure.
-
-This ioctl is supported if the ``V4L2_TUNER_CAP_FREQ_BANDS`` capability
-of the corresponding tuner/modulator is set.

-    * - __u32
-      - ``rangelow``
-      - :cspan:`2` The lowest tunable frequency in units of 62.5 kHz, or

-    * - __u32
-      - ``rangehigh``
-      - :cspan:`2` The highest tunable frequency in units of 62.5 kHz,
-	or if the ``capability`` flag ``V4L2_TUNER_CAP_LOW`` is set, in
-	units of 62.5 Hz, for this frequency band. A 1 Hz unit is used
-	when the ``capability`` flag ``V4L2_TUNER_CAP_1HZ`` is set.
-    * - __u32
-      - ``modulation``
-      - :cspan:`2` The supported modulation systems of this frequency
-	band. See :ref:`band-modulation`.
-
-	.. note::
-
-	   Currently only one modulation system per frequency band

-	number of bits can be set, or none.
-
-	When the driver does not enumerate audio outputs no bits must be
-	set. Applications shall not interpret this as lack of audio

-*******************
-
-Name
-====
-
-VIDIOC_EXPBUF - Export a buffer as a DMABUF file descriptor.
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_EXPBUF, struct v4l2_exportbuffer *argp )
-    :name: VIDIOC_EXPBUF
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_exportbuffer`.
-
-
-Description
-===========
-
-This ioctl is an extension to the :ref:`memory mapping <mmap>` I/O
-method, therefore it is available only for ``V4L2_MEMORY_MMAP`` buffers.
-It can be used to export a buffer as a DMABUF file at any time after
-buffers have been allocated with the
-:ref:`VIDIOC_REQBUFS` ioctl.
-
-To export a buffer, applications fill struct
-:c:type:`v4l2_exportbuffer`. The ``type`` field is
-set to the same buffer type as was previously used with struct
-:c:type:`v4l2_requestbuffers` ``type``.
-Applications must also set the ``index`` field. Valid index numbers
-range from zero to the number of buffers allocated with
-:ref:`VIDIOC_REQBUFS` (struct
-:c:type:`v4l2_requestbuffers` ``count``) minus
-one. For the multi-planar API, applications set the ``plane`` field to
-the index of the plane to be exported. Valid planes range from zero to
-the maximal number of valid planes for the currently active format. For
-the single-planar API, applications must set ``plane`` to zero.
-Additional flags may be posted in the ``flags`` field. Refer to a manual
-for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
-and O_RDWR are supported. All other fields must be set to zero. In the
-case of multi-planar API, every plane is exported separately using
-multiple :ref:`VIDIOC_EXPBUF` calls.
-
-After calling :ref:`VIDIOC_EXPBUF` the ``fd`` field will be set by a
-driver. This is a DMABUF file descriptor. The application may pass it to
-other DMABUF-aware devices. Refer to :ref:`DMABUF importing <dmabuf>`
-for details about importing DMABUF files into V4L2 nodes. It is
-recommended to close a DMABUF file when it is no longer used to allow
-the associated memory to be reclaimed.

-
-The driver first adjusts the requested dimensions against hardware
-limits, i. e. the bounds given by the capture/output window, and it
-rounds to the closest possible values of horizontal and vertical offset,
-width and height. In particular the driver must round the vertical
-offset of the cropping rectangle to frame lines modulo two, such that
-the field order cannot be confused.
-
-Second the driver adjusts the image size (the opposite rectangle of the
-scaling process, source or target depending on the data direction) to
-the closest size possible while maintaining the current horizontal and
-vertical scaling factor.
-
-Finally the driver programs the hardware with the actual cropping and
-image parameters. :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` is a write-only ioctl, it does not
-return the actual parameters. To query them applications must call
-:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_G_FMT`. When the
-parameters are unsuitable the application may modify the cropping or
-image parameters and repeat the cycle until satisfactory parameters have
-been negotiated.
-
-When cropping is not supported then no parameters are changed and
-:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` returns the ``EINVAL`` error code.

-    Pointer to struct :c:type:`v4l2_control`.
-
-
-Description
-===========
-
-To get the current value of a control applications initialize the ``id``
-field of a struct :c:type:`v4l2_control` and call the
-:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` ioctl with a pointer to this structure. To change the
-value of a control applications initialize the ``id`` and ``value``
-fields of a struct :c:type:`v4l2_control` and call the
-:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctl.
-
-When the ``id`` is invalid drivers return an ``EINVAL`` error code. When the
-``value`` is out of bounds drivers can choose to take the closest valid
-value or return an ``ERANGE`` error code, whatever seems more appropriate.
-However, :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` is a write-only ioctl, it does not return the
-actual new value. If the ``value`` is inappropriate for the control
-(e.g. if it refers to an unsupported menu index of a menu control), then
-EINVAL error code is returned as well.
-
-These ioctls work only with user controls. For other control classes the
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` or
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` must be used.

-Description
-===========
-
-To set DV timings for the input or output, applications use the
-:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get the current timings,
-applications use the :ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. The detailed timing
-information is filled in using the structure struct
-:c:type:`v4l2_dv_timings`. These ioctls take a
-pointer to the struct :c:type:`v4l2_dv_timings`
-structure as argument. If the ioctl is not supported or the timing
-values are not correct, the driver returns ``EINVAL`` error code.
-
-The ``linux/v4l2-dv-timings.h`` header can be used to get the timings of
-the formats in the :ref:`cea861` and :ref:`vesadmt` standards. If
-the current input or output does not support DV timings (e.g. if
-:ref:`VIDIOC_ENUMINPUT` does not set the
-``V4L2_IN_CAP_DV_TIMINGS`` flag), then ``ENODATA`` error code is returned.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EINVAL
-    This ioctl is not supported, or the :ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>`
-    parameter was unsuitable.
-
-ENODATA
-    Digital video timings are not supported for this input or output.
-

-
-    * - Flag
-      - Description
-    * - ``V4L2_DV_FL_REDUCED_BLANKING``
-      - CVT/GTF specific: the timings use reduced blanking (CVT) or the
-	'Secondary GTF' curve (GTF). In both cases the horizontal and/or
-	vertical blanking intervals are reduced, allowing a higher
-	resolution over the same bandwidth. This is a read-only flag,
-	applications must not set this.
-    * - ``V4L2_DV_FL_CAN_REDUCE_FPS``
-      - CEA-861 specific: set for CEA-861 formats with a framerate that is
-	a multiple of six. These formats can be optionally played at 1 /
-	1.001 speed to be compatible with 60 Hz based standards such as
-	NTSC and PAL-M that use a framerate of 29.97 frames per second. If
-	the transmitter can't generate such frequencies, then the flag
-	will also be cleared. This is a read-only flag, applications must
-	not set this.
-    * - ``V4L2_DV_FL_REDUCED_FPS``
-      - CEA-861 specific: only valid for video transmitters or video
-        receivers that have the ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
-	set. This flag is cleared otherwise. It is also only valid for
-	formats with the ``V4L2_DV_FL_CAN_REDUCE_FPS`` flag set, for other
-	formats the flag will be cleared by the driver.
-
-	If the application sets this flag for a transmitter, then the
-	pixelclock used to set up the transmitter is divided by 1.001 to
-	make it compatible with NTSC framerates. If the transmitter can't
-	generate such frequencies, then the flag will be cleared.
-
-	If a video receiver detects that the format uses a reduced framerate,
-	then it will set this flag to signal this to the application.
-    * - ``V4L2_DV_FL_HALF_LINE``
-      - Specific to interlaced formats: if set, then the vertical
-	frontporch of field 1 (aka the odd field) is really one half-line
-	longer and the vertical backporch of field 2 (aka the even field)
-	is really one half-line shorter, so each field has exactly the
-	same number of half-lines. Whether half-lines can be detected or
-	used depends on the hardware.
-    * - ``V4L2_DV_FL_IS_CE_VIDEO``
-      - If set, then this is a Consumer Electronics (CE) video format.
-	Such formats differ from other formats (commonly called IT
-	formats) in that if R'G'B' encoding is used then by default the
-	R'G'B' values use limited range (i.e. 16-235) as opposed to full
-	range (i.e. 0-255). All formats defined in CEA-861 except for the
-	640x480p59.94 format are CE formats.
-    * - ``V4L2_DV_FL_FIRST_FIELD_EXTRA_LINE``
-      - Some formats like SMPTE-125M have an interlaced signal with a odd
-	total height. For these formats, if this flag is set, the first
-	field has the extra line. Else, it is the second field.
-    * - ``V4L2_DV_FL_HAS_PICTURE_ASPECT``
-      - If set, then the picture_aspect field is valid. Otherwise assume that
-        the pixels are square, so the picture aspect ratio is the same as the
-	width to height ratio.
-    * - ``V4L2_DV_FL_HAS_CEA861_VIC``
-      - If set, then the cea861_vic field is valid and contains the Video
-        Identification Code as per the CEA-861 standard.
-    * - ``V4L2_DV_FL_HAS_HDMI_VIC``
-      - If set, then the hdmi_vic field is valid and contains the Video
-        Identification Code as per the HDMI standard (HDMI Vendor Specific
-	InfoFrame).
-    * - ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
-      - CEA-861 specific: only valid for video receivers, the flag is
-        cleared by transmitters.
-        If set, then the hardware can detect the difference between
-	regular framerates and framerates reduced by 1000/1001. E.g.:
-	60 vs 59.94 Hz, 30 vs 29.97 Hz or 24 vs 23.976 Hz.

-
-
-Description
-===========
-
-These ioctls can be used to get or set an EDID associated with an input
-from a receiver or an output of a transmitter device. They can be used
-with subdevice nodes (/dev/v4l-subdevX) or with video nodes
-(/dev/videoX).
-
-When used with video nodes the ``pad`` field represents the input (for
-video capture devices) or output (for video output devices) index as is
-returned by :ref:`VIDIOC_ENUMINPUT` and
-:ref:`VIDIOC_ENUMOUTPUT` respectively. When used
-with subdevice nodes the ``pad`` field represents the input or output
-pad of the subdevice. If there is no EDID support for the given ``pad``
-value, then the ``EINVAL`` error code will be returned.
-
-To get the EDID data the application has to fill in the ``pad``,
-``start_block``, ``blocks`` and ``edid`` fields, zero the ``reserved``
-array and call :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>`. The current EDID from block
-``start_block`` and of size ``blocks`` will be placed in the memory
-``edid`` points to. The ``edid`` pointer must point to memory at least
-``blocks`` * 128 bytes large (the size of one block is 128 bytes).
-
-If there are fewer blocks than specified, then the driver will set
-``blocks`` to the actual number of blocks. If there are no EDID blocks
-available at all, then the error code ``ENODATA`` is set.
-
-If blocks have to be retrieved from the sink, then this call will block
-until they have been read.
-
-If ``start_block`` and ``blocks`` are both set to 0 when
-:ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>` is called, then the driver will set ``blocks`` to the
-total number of available EDID blocks and it will return 0 without
-copying any data. This is an easy way to discover how many EDID blocks
-there are.
-
-.. note::
-
-   If there are no EDID blocks available at all, then
-   the driver will set ``blocks`` to 0 and it returns 0.
-
-To set the EDID blocks of a receiver the application has to fill in the
-``pad``, ``blocks`` and ``edid`` fields, set ``start_block`` to 0 and
-zero the ``reserved`` array. It is not possible to set part of an EDID,
-it is always all or nothing. Setting the EDID data is only valid for
-receivers as it makes no sense for a transmitter.
-
-The driver assumes that the full EDID is passed in. If there are more
-EDID blocks than the hardware can handle then the EDID is not written,
-but instead the error code ``E2BIG`` is set and ``blocks`` is set to the
-maximum that the hardware supports. If ``start_block`` is any value
-other than 0 then the error code ``EINVAL`` is set.
-
-To disable an EDID you set ``blocks`` to 0. Depending on the hardware
-this will drive the hotplug pin low and/or block the source from reading
-the EDID data in some way. In any case, the end result is the same: the
-EDID is no longer available.

-
-Description
-===========
-
-The :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` ioctl provides meta data about a compressed
-video stream the same or another application currently reads from the
-driver, which is useful for random access into the stream without
-decoding it.
-
-To read the data applications must call :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` with a
-pointer to a struct :c:type:`v4l2_enc_idx`. On success
-the driver fills the ``entry`` array, stores the number of elements
-written in the ``entries`` field, and initializes the ``entries_cap``
-field.
-
-Each element of the ``entry`` array contains meta data about one
-picture. A :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` call reads up to
-``V4L2_ENC_IDX_ENTRIES`` entries from a driver buffer, which can hold up
-to ``entries_cap`` entries. This number can be lower or higher than
-``V4L2_ENC_IDX_ENTRIES``, but not zero. When the application fails to
-read the meta data in time the oldest entries will be lost. When the
-buffer is empty or no capturing/encoding is in progress, ``entries``
-will be zero.
-
-Currently this ioctl is only defined for MPEG-2 program streams and
-video elementary streams.

-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_ext_controls`.
-
-
-Description
-===========
-
-These ioctls allow the caller to get or set multiple controls
-atomically. Control IDs are grouped into control classes (see
-:ref:`ctrl-class`) and all controls in the control array must belong
-to the same control class.
-
-Applications must always fill in the ``count``, ``which``, ``controls``
-and ``reserved`` fields of struct
-:c:type:`v4l2_ext_controls`, and initialize the
-struct :c:type:`v4l2_ext_control` array pointed to
-by the ``controls`` fields.
-
-To get the current value of a set of controls applications initialize
-the ``id``, ``size`` and ``reserved2`` fields of each struct
-:c:type:`v4l2_ext_control` and call the
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. String controls controls must also set the
-``string`` field. Controls of compound types
-(``V4L2_CTRL_FLAG_HAS_PAYLOAD`` is set) must set the ``ptr`` field.
-
-If the ``size`` is too small to receive the control result (only
-relevant for pointer-type controls like strings), then the driver will
-set ``size`` to a valid value and return an ``ENOSPC`` error code. You
-should re-allocate the memory to this new size and try again. For the
-string type it is possible that the same issue occurs again if the
-string has grown in the meantime. It is recommended to call
-:ref:`VIDIOC_QUERYCTRL` first and use
-``maximum``\ +1 as the new ``size`` value. It is guaranteed that that is
-sufficient memory.
-
-N-dimensional arrays are set and retrieved row-by-row. You cannot set a
-partial array, all elements have to be set or retrieved. The total size
-is calculated as ``elems`` * ``elem_size``. These values can be obtained
-by calling :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>`.
-
-To change the value of a set of controls applications initialize the
-``id``, ``size``, ``reserved2`` and ``value/value64/string/ptr`` fields
-of each struct :c:type:`v4l2_ext_control` and call
-the :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. The controls will only be set if *all*
-control values are valid.
-
-To check if a set of controls have correct values applications
-initialize the ``id``, ``size``, ``reserved2`` and
-``value/value64/string/ptr`` fields of each struct
-:c:type:`v4l2_ext_control` and call the
-:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. It is up to the driver whether wrong
-values are automatically adjusted to a valid value or if an error is
-returned.
-
-When the ``id`` or ``which`` is invalid drivers return an ``EINVAL`` error
-code. When the value is out of bounds drivers can choose to take the
-closest valid value or return an ``ERANGE`` error code, whatever seems more
-appropriate. In the first case the new value is set in struct
-:c:type:`v4l2_ext_control`. If the new control value
-is inappropriate (e.g. the given menu index is not supported by the menu
-control), then this will also result in an ``EINVAL`` error code error.
-
-If ``request_fd`` is set to a not-yet-queued :ref:`request <media-request-api>`
-file descriptor and ``which`` is set to ``V4L2_CTRL_WHICH_REQUEST_VAL``,
-then the controls are not applied immediately when calling
-:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, but instead are applied by
-the driver for the buffer associated with the same request.
-If the device does not support requests, then ``EACCES`` will be returned.
-If requests are supported but an invalid request file descriptor is given,
-then ``EINVAL`` will be returned.
-
-An attempt to call :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
-request that has already been queued will result in an ``EBUSY`` error.
-
-If ``request_fd`` is specified and ``which`` is set to
-``V4L2_CTRL_WHICH_REQUEST_VAL`` during a call to
-:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then it will return the
-values of the controls at the time of request completion.
-If the request is not yet completed, then this will result in an
-``EACCES`` error.
-
-The driver will only set/get these controls if all control values are
-correct. This prevents the situation where only some of the controls
-were set/get. Only low-level errors (e. g. a failed i2c command) can
-still cause this situation.

-	the controls can belong to any control class. Whether drivers

-
-	   When using ``V4L2_CTRL_WHICH_DEF_VAL`` be aware that you can only

-
-	For backwards compatibility you can also use a control class here
-	(see :ref:`ctrl-class`). In that case all controls have to
-	belong to that control class. This usage is deprecated, instead
-	just use ``V4L2_CTRL_WHICH_CUR_VAL``. There are some very old
-	drivers that do not yet support ``V4L2_CTRL_WHICH_CUR_VAL`` and
-	that require a control class here. You can test for such drivers
-	by setting ctrl_class to ``V4L2_CTRL_WHICH_CUR_VAL`` and calling
-	VIDIOC_TRY_EXT_CTRLS with a count of 0. If that fails, then the
-	driver does not support ``V4L2_CTRL_WHICH_CUR_VAL``.

-    * - __u32
-      - ``count``
-      - The number of controls in the controls array. May also be zero.
-    * - __u32
-      - ``error_idx``
-      - Set by the driver in case of an error. If the error is associated
-	with a particular control, then ``error_idx`` is set to the index
-	of that control. If the error is not related to a specific
-	control, or the validation step failed (see below), then
-	``error_idx`` is set to ``count``. The value is undefined if the
-	ioctl returned 0 (success).
-
-	Before controls are read from/written to hardware a validation
-	step takes place: this checks if all controls in the list are
-	valid controls, if no attempt is made to write to a read-only
-	control or read from a write-only control, and any other up-front
-	checks that can be done without accessing the hardware. The exact
-	validations done during this step are driver dependent since some
-	checks might require hardware access for some devices, thus making
-	it impossible to do those checks up-front. However, drivers should
-	make a best-effort to do as many up-front checks as possible.
-
-	This check is done to avoid leaving the hardware in an
-	inconsistent state due to easy-to-avoid problems. But it leads to
-	another problem: the application needs to know whether an error
-	came from the validation step (meaning that the hardware was not
-	touched) or from an error during the actual reading from/writing
-	to hardware.
-
-	The, in hindsight quite poor, solution for that is to set

-	and the error happened while accessing the hardware, then

-	the remaining controls is undefined.
-
-	Since :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` does not access hardware there is
-	also no need to handle the validation step in this special way, so
-	``error_idx`` will just be set to the control that failed the
-	validation step instead of to ``count``. This means that if
-	:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` fails with ``error_idx`` set to ``count``,
-	then you can call :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` to try to discover the

-Description
-===========
-
-Applications can use the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl
-to get and set the framebuffer parameters for a
-:ref:`Video Overlay <overlay>` or :ref:`Video Output Overlay <osd>`
-(OSD). The type of overlay is implied by the device type (capture or
-output device) and can be determined with the
-:ref:`VIDIOC_QUERYCAP` ioctl. One ``/dev/videoN``
-device must not support both kinds of overlay.
-
-The V4L2 API distinguishes destructive and non-destructive overlays. A
-destructive overlay copies captured video images into the video memory
-of a graphics card. A non-destructive overlay blends video images into a
-VGA signal or graphics into a video signal. *Video Output Overlays* are
-always non-destructive.
-
-To get the current parameters applications call the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-ioctl with a pointer to a struct :c:type:`v4l2_framebuffer`
-structure. The driver fills all fields of the structure or returns an
-EINVAL error code when overlays are not supported.
-
-To set the parameters for a *Video Output Overlay*, applications must
-initialize the ``flags`` field of a struct
-:c:type:`v4l2_framebuffer`. Since the framebuffer is
-implemented on the TV card all other parameters are determined by the
-driver. When an application calls :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` with a pointer to
-this structure, the driver prepares for the overlay and returns the
-framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` does, or it returns an error
-code.
-
-To set the parameters for a *non-destructive Video Overlay*,
-applications must initialize the ``flags`` field, the ``fmt``
-substructure, and call :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. Again the driver prepares for
-the overlay and returns the framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
-does, or it returns an error code.
-
-For a *destructive Video Overlay* applications must additionally provide
-a ``base`` address. Setting up a DMA to a random memory location can
-jeopardize the system security, its stability or even damage the
-hardware, therefore only the superuser can set the parameters for a
-destructive video overlay.

-      - This field is irrelevant to *non-destructive Video Overlays*. For
-	*destructive Video Overlays* applications must provide a base
-	address. The driver may accept only base addresses which are a
-	multiple of two, four or eight bytes. For *Video Output Overlays*

-	format for the struct :c:type:`v4l2_window`
-	``chromakey`` field.
-    * -
-      -
-      -
-      - For *destructive Video Overlays* applications must initialize this
-	field. For *Video Output Overlays* the driver must return a valid
-	format.
-    * -
-      -
-      -
-      - Usually this is an RGB format (for example
-	:ref:`V4L2_PIX_FMT_RGB565 <V4L2-PIX-FMT-RGB565>`) but YUV
-	formats (only packed YUV formats when chroma keying is used, not
-	including ``V4L2_PIX_FMT_YUYV`` and ``V4L2_PIX_FMT_UYVY``) and the
-	``V4L2_PIX_FMT_PAL8`` format are also permitted. The behavior of
-	the driver when an application requests a compressed format is
-	undefined. See :ref:`pixfmt` for information on pixel formats.
-    * -
-      - enum :c:type:`v4l2_field`
-      - ``field``
-      - Drivers and applications shall ignore this field. If applicable,
-	the field order is selected with the
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, using the ``field``
-	field of struct :c:type:`v4l2_window`.
-    * -
-      - __u32
-      - ``bytesperline``
-      - Distance in bytes between the leftmost pixels in two adjacent
-	lines.
-    * - :cspan:`3`
-
-	This field is irrelevant to *non-destructive Video Overlays*.
-
-	For *destructive Video Overlays* both applications and drivers can
-	set this field to request padding bytes at the end of each line.
-	Drivers however may ignore the requested value, returning
-	``width`` times bytes-per-pixel or a larger value required by the
-	hardware. That implies applications can just set this field to
-	zero to get a reasonable default.
-
-	For *Video Output Overlays* the driver must return a valid value.
-
-	Video hardware may access padding bytes, therefore they must
-	reside in accessible memory. Consider for example the case where
-	padding bytes after the last line of an image cross a system page
-	boundary. Capture devices may write padding bytes, the value is
-	undefined. Output devices ignore the contents of padding bytes.
-
-	When the image format is planar the ``bytesperline`` value applies
-	to the first plane and is divided by the same factor as the
-	``width`` field for the other planes. For example the Cb and Cr
-	planes of a YUV 4:2:0 image have half as many padding bytes
-	following each line as the Y plane. To avoid ambiguities drivers
-	must return a ``bytesperline`` value rounded up to a multiple of
-	the scale factor.
-    * -
-      - __u32
-      - ``sizeimage``
-      - This field is irrelevant to *non-destructive Video Overlays*. For
-	*destructive Video Overlays* applications must initialize this
-	field. For *Video Output Overlays* the driver must return a valid
-	format.
-
-	Together with ``base`` it defines the framebuffer memory
-	accessible by the driver.
-    * -
-      - enum :c:type:`v4l2_colorspace`

-
-    * - ``V4L2_FBUF_CAP_EXTERNOVERLAY``
-      - 0x0001
-      - The device is capable of non-destructive overlays. When the driver
-	clears this flag, only destructive overlays are supported. There
-	are no drivers yet which support both destructive and
-	non-destructive overlays. Video Output Overlays are in practice
-	always non-destructive.
-    * - ``V4L2_FBUF_CAP_CHROMAKEY``
-      - 0x0002
-      - The device supports clipping by chroma-keying the images. That is,
-	image pixels replace pixels in the VGA or video signal only where
-	the latter assume a certain color. Chroma-keying makes no sense
-	for destructive overlays.
-    * - ``V4L2_FBUF_CAP_LIST_CLIPPING``
-      - 0x0004
-      - The device supports clipping using a list of clip rectangles.
-    * - ``V4L2_FBUF_CAP_BITMAP_CLIPPING``
-      - 0x0008
-      - The device supports clipping using a bit mask.
-    * - ``V4L2_FBUF_CAP_LOCAL_ALPHA``
-      - 0x0010
-      - The device supports clipping/blending using the alpha channel of
-	the framebuffer or VGA signal. Alpha blending makes no sense for
-	destructive overlays.
-    * - ``V4L2_FBUF_CAP_GLOBAL_ALPHA``
-      - 0x0020
-      - The device supports alpha blending using a global alpha value.
-	Alpha blending makes no sense for destructive overlays.
-    * - ``V4L2_FBUF_CAP_LOCAL_INV_ALPHA``
-      - 0x0040
-      - The device supports clipping/blending using the inverted alpha
-	channel of the framebuffer or VGA signal. Alpha blending makes no
-	sense for destructive overlays.
-    * - ``V4L2_FBUF_CAP_SRC_CHROMAKEY``
-      - 0x0080
-      - The device supports Source Chroma-keying. Video pixels with the
-	chroma-key colors are replaced by framebuffer pixels, which is
-	exactly opposite of ``V4L2_FBUF_CAP_CHROMAKEY``

-
-    * - ``V4L2_FBUF_FLAG_PRIMARY``
-      - 0x0001
-      - The framebuffer is the primary graphics surface. In other words,
-	the overlay is destructive. This flag is typically set by any
-	driver that doesn't have the ``V4L2_FBUF_CAP_EXTERNOVERLAY``
-	capability and it is cleared otherwise.
-    * - ``V4L2_FBUF_FLAG_OVERLAY``
-      - 0x0002
-      - If this flag is set for a video capture device, then the driver
-	will set the initial overlay size to cover the full framebuffer
-	size, otherwise the existing overlay size (as set by
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) will be used. Only one
-	video capture driver (bttv) supports this flag. The use of this
-	flag for capture devices is deprecated. There is no way to detect
-	which drivers support this flag, so the only reliable method of
-	setting the overlay size is through
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. If this flag is set for a
-	video output device, then the video output overlay window is
-	relative to the top-left corner of the framebuffer and restricted
-	to the size of the framebuffer. If it is cleared, then the video
-	output overlay window is relative to the video output display.
-    * - ``V4L2_FBUF_FLAG_CHROMAKEY``
-      - 0x0004
-      - Use chroma-keying. The chroma-key color is determined by the
-	``chromakey`` field of struct :c:type:`v4l2_window`
-	and negotiated with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-	ioctl, see :ref:`overlay` and :ref:`osd`.
-    * - :cspan:`2` There are no flags to enable clipping using a list of
-	clip rectangles or a bitmap. These methods are negotiated with the
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, see :ref:`overlay`
-	and :ref:`osd`.
-    * - ``V4L2_FBUF_FLAG_LOCAL_ALPHA``
-      - 0x0008
-      - Use the alpha channel of the framebuffer to clip or blend
-	framebuffer pixels with video images. The blend function is:
-	output = framebuffer pixel * alpha + video pixel * (1 - alpha).
-	The actual alpha depth depends on the framebuffer pixel format.
-    * - ``V4L2_FBUF_FLAG_GLOBAL_ALPHA``
-      - 0x0010
-      - Use a global alpha value to blend the framebuffer with video
-	images. The blend function is: output = (framebuffer pixel * alpha
-	+ video pixel * (255 - alpha)) / 255. The alpha value is
-	determined by the ``global_alpha`` field of struct
-	:c:type:`v4l2_window` and negotiated with the
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, see :ref:`overlay`
-	and :ref:`osd`.
-    * - ``V4L2_FBUF_FLAG_LOCAL_INV_ALPHA``
-      - 0x0020
-      - Like ``V4L2_FBUF_FLAG_LOCAL_ALPHA``, use the alpha channel of the
-	framebuffer to clip or blend framebuffer pixels with video images,
-	but with an inverted alpha value. The blend function is: output =
-	framebuffer pixel * (1 - alpha) + video pixel * alpha. The actual
-	alpha depth depends on the framebuffer pixel format.
-    * - ``V4L2_FBUF_FLAG_SRC_CHROMAKEY``
-      - 0x0040
-      - Use source chroma-keying. The source chroma-key color is
-	determined by the ``chromakey`` field of struct
-	:c:type:`v4l2_window` and negotiated with the
-	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, see :ref:`overlay`
-	and :ref:`osd`. Both chroma-keying are mutual exclusive to each
-	other, so same ``chromakey`` field of struct
-	:c:type:`v4l2_window` is being used.

-Description
-===========
-
-These ioctls are used to negotiate the format of data (typically image
-format) exchanged between driver and application.
-
-To query the current parameters applications set the ``type`` field of a
-struct :c:type:`v4l2_format` to the respective buffer (stream)
-type. For example video capture devices use
-``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
-``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``. When the application calls the
-:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this structure the driver fills
-the respective member of the ``fmt`` union. In case of video capture
-devices that is either the struct
-:c:type:`v4l2_pix_format` ``pix`` or the struct
-:c:type:`v4l2_pix_format_mplane` ``pix_mp``
-member. When the requested buffer type is not supported drivers return
-an ``EINVAL`` error code.
-
-To change the current format parameters applications initialize the
-``type`` field and all fields of the respective ``fmt`` union member.
-For details see the documentation of the various devices types in
-:ref:`devices`. Good practice is to query the current parameters
-first, and to modify only those parameters not suitable for the
-application. When the application calls the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with
-a pointer to a struct :c:type:`v4l2_format` structure the driver
-checks and adjusts the parameters against hardware abilities. Drivers
-should not return an error code unless the ``type`` field is invalid,
-this is a mechanism to fathom device capabilities and to approach
-parameters acceptable for both the application and driver. On success
-the driver may program the hardware, allocate resources and generally
-prepare for data exchange. Finally the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl returns
-the current format parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Very simple,
-inflexible devices may even ignore all input and always return the
-default parameters. However all V4L2 devices exchanging data with the
-application must implement the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
-ioctl. When the requested buffer type is not supported drivers return an
-EINVAL error code on a :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` attempt. When I/O is already in
-progress or the resource is not available for other reasons drivers
-return the ``EBUSY`` error code.
-
-The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl is equivalent to :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` with one
-exception: it does not change driver state. It can also be called at any
-time, never returning ``EBUSY``. This function is provided to negotiate
-parameters, to learn about hardware limitations, without disabling I/O
-or possibly time consuming hardware preparations. Although strongly
-recommended drivers are not required to implement this ioctl.
-
-The format as returned by :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` must be identical to what
-:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` returns for the same input or output.

-Description
-===========
-
-To get the current tuner or modulator radio frequency applications set
-the ``tuner`` field of a struct
-:c:type:`v4l2_frequency` to the respective tuner or
-modulator number (only input devices have tuners, only output devices
-have modulators), zero out the ``reserved`` array and call the
-:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this structure. The
-driver stores the current frequency in the ``frequency`` field.
-
-To change the current tuner or modulator radio frequency applications
-initialize the ``tuner``, ``type`` and ``frequency`` fields, and the
-``reserved`` array of a struct :c:type:`v4l2_frequency`
-and call the :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this
-structure. When the requested frequency is not possible the driver
-assumes the closest possible value. However :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` is a
-write-only ioctl, it does not return the actual new frequency.

-Ronald Bultje elaborates:
-
-APP is some application-specific information. The application can set it
-itself, and it'll be stored in the JPEG-encoded fields (eg; interlacing
-information for in an AVI or so). COM is the same, but it's comments,
-like 'encoded by me' or so.
-
-jpeg_markers describes whether the huffman tables, quantization tables
-and the restart interval information (all JPEG-specific stuff) should be
-stored in the JPEG-encoded fields. These define how the JPEG field is
-encoded. If you omit them, applications assume you've used standard
-encoding. You usually do want to add them.

-
-To query the attributes of a modulator applications initialize the

-begin at index zero, incrementing by one until the driver returns
-EINVAL.
-
-Modulators have two writable properties, an audio modulation set and the
-radio frequency. To change the modulated audio subprograms, applications
-initialize the ``index`` and ``txsubchans`` fields and the ``reserved``
-array and call the :ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Drivers may choose a

-this is a write-only ioctl, it does not return the actual audio
-modulation selected.
-
-:ref:`SDR <sdr>` specific modulator types are ``V4L2_TUNER_SDR`` and
-``V4L2_TUNER_RF``. For SDR devices ``txsubchans`` field must be
-initialized to zero. The term 'modulator' means SDR transmitter in this

-Description
-===========
-
-The current video standard determines a nominal number of frames per
-second. If less than this number of frames is to be captured or output,
-applications can request frame skipping or duplicating on the driver
-side. This is especially useful when using the :ref:`read() <func-read>` or
-:ref:`write() <func-write>`, which are not augmented by timestamps or sequence
-counters, and to avoid unnecessary data copying.
-
-Changing the frame interval shall never change the format. Changing the
-format, on the other hand, may change the frame interval.
-
-Further these ioctls can be used to determine the number of buffers used
-internally by a driver in read/write mode. For implications see the
-section discussing the :ref:`read() <func-read>` function.
-
-To get and set the streaming parameters applications call the
-:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take a
-pointer to a struct :c:type:`v4l2_streamparm` which contains a
-union holding separate parameters for input and output devices.

-
-	-  The driver may support fewer pixel formats than motion capture

-
-	-  The driver may capture and arithmetically combine multiple

-	   reduce the noise in the video data.
-
-	-  The driver may capture images in slices like a scanner in order
-	   to handle larger format images than would otherwise be
-	   possible.
-
-	-  An image capture operation may be significantly slower than
-	   motion capture.
-
-	-  Moving objects in the image might have excessive motion blur.

-Description
-===========
-
-The ioctls are used to query and configure selection rectangles.
-
-To query the cropping (composing) rectangle set struct
-:c:type:`v4l2_selection` ``type`` field to the
-respective buffer type. The next step is setting the
-value of struct :c:type:`v4l2_selection` ``target``
-field to ``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer
-to table :ref:`v4l2-selections-common` or :ref:`selection-api` for
-additional targets. The ``flags`` and ``reserved`` fields of struct
-:c:type:`v4l2_selection` are ignored and they must be
-filled with zeros. The driver fills the rest of the structure or returns
-EINVAL error code if incorrect buffer type or target was used. If
-cropping (composing) is not supported then the active rectangle is not
-mutable and it is always equal to the bounds rectangle. Finally, the
-struct :c:type:`v4l2_rect` ``r`` rectangle is filled with
-the current cropping (composing) coordinates. The coordinates are
-expressed in driver-dependent units. The only exception are rectangles
-for images in raw formats, whose coordinates are always expressed in
-pixels.
-
-To change the cropping (composing) rectangle set the struct
-:c:type:`v4l2_selection` ``type`` field to the
-respective buffer type. The next step is setting the
-value of struct :c:type:`v4l2_selection` ``target`` to
-``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer to table
-:ref:`v4l2-selections-common` or :ref:`selection-api` for additional
-targets. The struct :c:type:`v4l2_rect` ``r`` rectangle need
-to be set to the desired active area. Field struct
-:c:type:`v4l2_selection` ``reserved`` is ignored and
-must be filled with zeros. The driver may adjust coordinates of the
-requested rectangle. An application may introduce constraints to control
-rounding behaviour. The struct :c:type:`v4l2_selection`
-``flags`` field must be set to one of the following:
-
--  ``0`` - The driver can adjust the rectangle size freely and shall
-   choose a crop/compose rectangle as close as possible to the requested
-   one.
-
--  ``V4L2_SEL_FLAG_GE`` - The driver is not allowed to shrink the
-   rectangle. The original rectangle must lay inside the adjusted one.
-
--  ``V4L2_SEL_FLAG_LE`` - The driver is not allowed to enlarge the
-   rectangle. The adjusted rectangle must lay inside the original one.

--  ``V4L2_SEL_FLAG_GE | V4L2_SEL_FLAG_LE`` - The driver must choose the
-   size exactly the same as in the requested rectangle.
-
-Please refer to :ref:`sel-const-adjust`.
-
-The driver may have to adjusts the requested dimensions against hardware
-limits and other parts as the pipeline, i.e. the bounds given by the
-capture/output window or TV display. The closest possible values of
-horizontal and vertical offset and sizes are chosen according to
-following priority:
-
-1. Satisfy constraints from struct
-   :c:type:`v4l2_selection` ``flags``.
-
-2. Adjust width, height, left, and top to hardware limits and
-   alignments.
-
-3. Keep center of adjusted rectangle as close as possible to the
-   original one.
-
-4. Keep width and height as close as possible to original ones.
-
-5. Keep horizontal and vertical offset as close as possible to original
-   ones.
-
-On success the struct :c:type:`v4l2_rect` ``r`` field
-contains the adjusted rectangle. When the parameters are unsuitable the
-application may modify the cropping (composing) or image parameters and
-repeat the cycle until satisfactory parameters have been negotiated. If
-constraints flags have to be violated at then ``ERANGE`` is returned. The
-error indicates that *there exist no rectangle* that satisfies the
-constraints.
-
-Selection targets and flags are documented in

-
-Description
-===========
-
-To query the attributes of a tuner applications initialize the ``index``
-field and zero out the ``reserved`` array of a struct
-:c:type:`v4l2_tuner` and call the ``VIDIOC_G_TUNER`` ioctl
-with a pointer to this structure. Drivers fill the rest of the structure
-or return an ``EINVAL`` error code when the index is out of bounds. To
-enumerate all tuners applications shall begin at index zero,
-incrementing by one until the driver returns ``EINVAL``.
-
-Tuners have two writable properties, the audio mode and the radio
-frequency. To change the audio mode, applications initialize the
-``index``, ``audmode`` and ``reserved`` fields and call the
-``VIDIOC_S_TUNER`` ioctl. This will *not* change the current tuner,
-which is determined by the current video input. Drivers may choose a
-different audio mode if the requested mode is invalid or unsupported.
-Since this is a write-only ioctl, it does not return the actually
-selected audio mode.
-
-:ref:`SDR <sdr>` specific tuner types are ``V4L2_TUNER_SDR`` and
-``V4L2_TUNER_RF``. For SDR devices ``audmode`` field must be initialized
-to zero. The term 'tuner' means SDR receiver in this context.
-
-To change the radio frequency the
-:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

-      - receiving bilingual audio
-    * -
-      -

-      - receiving mono, stereo or bilingual audio
-    * -
-      -
-      - :cspan:`1`
-
-	When the ``V4L2_TUNER_CAP_STEREO``, ``_LANG1``, ``_LANG2`` or
-	``_SAP`` flag is cleared in the ``capability`` field, the
-	corresponding ``V4L2_TUNER_SUB_`` flag must not be set here.
-
-	This field is valid only if this is the tuner of the current video
-	input, or when the structure refers to a radio tuner.
-    * - __u32
-      - ``audmode``
-      - :cspan:`1`
-
-	The selected audio mode, see :ref:`tuner-audmode` for valid

-	and like a :ref:`control` it does not automatically
-	change unless the requested mode is invalid or unsupported. See
-	:ref:`tuner-matrix` for possible results when the selected and

-
-
-Description
-===========
-
-As the video/audio devices become more complicated it becomes harder to
-debug problems. When this ioctl is called the driver will output the
-current device status to the kernel log. This is particular useful when
-dealing with problems like no sound, no video and incorrectly tuned
-channels. Also many modern devices autodetect video and audio standards
-and this ioctl will report what the device thinks what the standard is.
-Mismatches may give an indication where the problem is.
-
-This ioctl is optional and not all drivers support it. It was introduced
-in Linux 2.6.15.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-

-
-
-Description
-===========
-
-Applications call the ``VIDIOC_QBUF`` ioctl to enqueue an empty
-(capturing) or filled (output) buffer in the driver's incoming queue.
-The semantics depend on the selected I/O method.
-
-To enqueue a buffer applications set the ``type`` field of a struct
-:c:type:`v4l2_buffer` to the same buffer type as was
-previously used with struct :c:type:`v4l2_format` ``type``
-and struct :c:type:`v4l2_requestbuffers` ``type``.
-Applications must also set the ``index`` field. Valid index numbers
-range from zero to the number of buffers allocated with
-:ref:`VIDIOC_REQBUFS` (struct
-:c:type:`v4l2_requestbuffers` ``count``) minus
-one. The contents of the struct :c:type:`v4l2_buffer` returned
-by a :ref:`VIDIOC_QUERYBUF` ioctl will do as well.
-When the buffer is intended for output (``type`` is
-``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``,
-or ``V4L2_BUF_TYPE_VBI_OUTPUT``) applications must also initialize the
-``bytesused``, ``field`` and ``timestamp`` fields, see :ref:`buffer`
-for details. Applications must also set ``flags`` to 0. The
-``reserved2`` and ``reserved`` fields must be set to 0. When using the
-:ref:`multi-planar API <planar-apis>`, the ``m.planes`` field must
-contain a userspace pointer to a filled-in array of struct
-:c:type:`v4l2_plane` and the ``length`` field must be set
-to the number of elements in that array.
-
-To enqueue a :ref:`memory mapped <mmap>` buffer applications set the
-``memory`` field to ``V4L2_MEMORY_MMAP``. When ``VIDIOC_QBUF`` is called
-with a pointer to this structure the driver sets the
-``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_QUEUED`` flags and clears
-the ``V4L2_BUF_FLAG_DONE`` flag in the ``flags`` field, or it returns an
-``EINVAL`` error code.
-
-To enqueue a :ref:`user pointer <userp>` buffer applications set the
-``memory`` field to ``V4L2_MEMORY_USERPTR``, the ``m.userptr`` field to
-the address of the buffer and ``length`` to its size. When the
-multi-planar API is used, ``m.userptr`` and ``length`` members of the
-passed array of struct :c:type:`v4l2_plane` have to be used
-instead. When ``VIDIOC_QBUF`` is called with a pointer to this structure
-the driver sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
-``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
-``flags`` field, or it returns an error code. This ioctl locks the
-memory pages of the buffer in physical memory, they cannot be swapped
-out to disk. Buffers remain locked until dequeued, until the
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
-:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
-device is closed.
-
-To enqueue a :ref:`DMABUF <dmabuf>` buffer applications set the
-``memory`` field to ``V4L2_MEMORY_DMABUF`` and the ``m.fd`` field to a
-file descriptor associated with a DMABUF buffer. When the multi-planar
-API is used the ``m.fd`` fields of the passed array of struct
-:c:type:`v4l2_plane` have to be used instead. When
-``VIDIOC_QBUF`` is called with a pointer to this structure the driver
-sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
-``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
-``flags`` field, or it returns an error code. This ioctl locks the
-buffer. Locking a buffer means passing it to a driver for a hardware
-access (usually DMA). If an application accesses (reads/writes) a locked
-buffer then the result is undefined. Buffers remain locked until
-dequeued, until the :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
-:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
-device is closed.
-
-The ``request_fd`` field can be used with the ``VIDIOC_QBUF`` ioctl to specify
-the file descriptor of a :ref:`request <media-request-api>`, if requests are
-in use. Setting it means that the buffer will not be passed to the driver
-until the request itself is queued. Also, the driver will apply any
-settings associated with the request for this buffer. This field will
-be ignored unless the ``V4L2_BUF_FLAG_REQUEST_FD`` flag is set.
-If the device does not support requests, then ``EBADR`` will be returned.
-If requests are supported but an invalid request file descriptor is given,
-then ``EINVAL`` will be returned.
-
-.. caution::
-   It is not allowed to mix queuing requests with queuing buffers directly.
-   ``EBUSY`` will be returned if the first buffer was queued directly and
-   then the application tries to queue a request, or vice versa. After
-   closing the file descriptor, calling
-   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or calling :ref:`VIDIOC_REQBUFS`
-   the check for this will be reset.
-
-   For :ref:`memory-to-memory devices <mem2mem>` you can specify the
-   ``request_fd`` only for output buffers, not for capture buffers. Attempting
-   to specify this for a capture buffer will result in an ``EBADR`` error.
-
-Applications call the ``VIDIOC_DQBUF`` ioctl to dequeue a filled
-(capturing) or displayed (output) buffer from the driver's outgoing
-queue. They just set the ``type``, ``memory`` and ``reserved`` fields of
-a struct :c:type:`v4l2_buffer` as above, when
-``VIDIOC_DQBUF`` is called with a pointer to this structure the driver
-fills the remaining fields or returns an error code. The driver may also
-set ``V4L2_BUF_FLAG_ERROR`` in the ``flags`` field. It indicates a
-non-critical (recoverable) streaming error. In such case the application
-may continue as normal, but should be aware that data in the dequeued
-buffer might be corrupted. When using the multi-planar API, the planes
-array must be passed in as well.
-
-If the application sets the ``memory`` field to ``V4L2_MEMORY_DMABUF`` to
-dequeue a :ref:`DMABUF <dmabuf>` buffer, the driver fills the ``m.fd`` field
-with a file descriptor numerically the same as the one given to ``VIDIOC_QBUF``
-when the buffer was enqueued. No new file descriptor is created at dequeue time
-and the value is only for the application convenience. When the multi-planar
-API is used the ``m.fd`` fields of the passed array of struct
-:c:type:`v4l2_plane` are filled instead.
-
-By default ``VIDIOC_DQBUF`` blocks when no buffer is in the outgoing
-queue. When the ``O_NONBLOCK`` flag was given to the
-:ref:`open() <func-open>` function, ``VIDIOC_DQBUF`` returns
-immediately with an ``EAGAIN`` error code when no buffer is available.
-
-The struct :c:type:`v4l2_buffer` structure is specified in
-:ref:`buffer`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-EAGAIN
-    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
-    buffer was in the outgoing queue.
-
-EINVAL
-    The buffer ``type`` is not supported, or the ``index`` is out of
-    bounds, or no buffers have been allocated yet, or the ``userptr`` or
-    ``length`` are invalid, or the ``V4L2_BUF_FLAG_REQUEST_FD`` flag was
-    set but the the given ``request_fd`` was invalid, or ``m.fd`` was
-    an invalid DMABUF file descriptor.
-
-EIO
-    ``VIDIOC_DQBUF`` failed due to an internal error. Can also indicate
-    temporary problems like signal loss.
-
-    .. note::
-
-       The driver might dequeue an (empty) buffer despite returning
-       an error, or even stop capturing. Reusing such buffer may be unsafe
-       though and its details (e.g. ``index``) may not be returned either.
-       It is recommended that drivers indicate recoverable errors by setting
-       the ``V4L2_BUF_FLAG_ERROR`` and returning 0 instead. In that case the
-       application should be able to safely reuse the buffer and continue
-       streaming.
-
-EPIPE
-    ``VIDIOC_DQBUF`` returns this on an empty capture queue for mem2mem
-    codecs if a buffer with the ``V4L2_BUF_FLAG_LAST`` was already
-    dequeued and no new buffers are expected to become available.
-
-EBADR
-    The ``V4L2_BUF_FLAG_REQUEST_FD`` flag was set but the device does not
-    support requests for the given buffer type, or
-    the ``V4L2_BUF_FLAG_REQUEST_FD`` flag was not set but the device requires
-    that the buffer is part of a request.
-
-EBUSY
-    The first buffer was queued via a request, but the application now tries
-    to queue it directly, or vice versa (it is not permitted to mix the two
-    APIs).

-
-
-Description
-===========
-
-The hardware may be able to detect the current DV timings automatically,
-similar to sensing the video standard. To do so, applications call
-:ref:`VIDIOC_QUERY_DV_TIMINGS` with a pointer to a struct
-:c:type:`v4l2_dv_timings`. Once the hardware detects
-the timings, it will fill in the timings structure.
-
-.. note::
-
-   Drivers shall *not* switch timings automatically if new
-   timings are detected. Instead, drivers should send the
-   ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support this) and expect
-   that userspace will take action by calling :ref:`VIDIOC_QUERY_DV_TIMINGS`.
-   The reason is that new timings usually mean different buffer sizes as
-   well, and you cannot change buffer sizes on the fly. In general,
-   applications that receive the Source Change event will have to call
-   :ref:`VIDIOC_QUERY_DV_TIMINGS`, and if the detected timings are valid they
-   will have to stop streaming, set the new timings, allocate new buffers
-   and start streaming again.
-
-If the timings could not be detected because there was no signal, then
-ENOLINK is returned. If a signal was detected, but it was unstable and
-the receiver could not lock to the signal, then ``ENOLCK`` is returned. If
-the receiver could lock to the signal, but the format is unsupported
-(e.g. because the pixelclock is out of range of the hardware
-capabilities), then the driver fills in whatever timings it could find
-and returns ``ERANGE``. In that case the application can call
-:ref:`VIDIOC_DV_TIMINGS_CAP` to compare the
-found timings with the hardware's capabilities in order to give more
-precise feedback to the user.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-ENODATA
-    Digital video timings are not supported for this input or output.
-
-ENOLINK
-    No timings could be detected because no signal was found.
-
-ENOLCK
-    The signal was unstable and the hardware could not lock on to it.
-
-ERANGE
-    Timings were found, but they are out of range of the hardware
-    capabilities.

-
-Description
-===========
-
-This ioctl is part of the :ref:`streaming <mmap>` I/O method. It can
-be used to query the status of a buffer at any time after buffers have
-been allocated with the :ref:`VIDIOC_REQBUFS` ioctl.
-
-Applications set the ``type`` field of a struct
-:c:type:`v4l2_buffer` to the same buffer type as was
-previously used with struct :c:type:`v4l2_format` ``type``
-and struct :c:type:`v4l2_requestbuffers` ``type``,
-and the ``index`` field. Valid index numbers range from zero to the
-number of buffers allocated with
-:ref:`VIDIOC_REQBUFS` (struct
-:c:type:`v4l2_requestbuffers` ``count``) minus
-one. The ``reserved`` and ``reserved2`` fields must be set to 0. When
-using the :ref:`multi-planar API <planar-apis>`, the ``m.planes``
-field must contain a userspace pointer to an array of struct
-:c:type:`v4l2_plane` and the ``length`` field has to be set
-to the number of elements in that array. After calling
-:ref:`VIDIOC_QUERYBUF` with a pointer to this structure drivers return an
-error code or fill the rest of the structure.
-
-In the ``flags`` field the ``V4L2_BUF_FLAG_MAPPED``,
-``V4L2_BUF_FLAG_PREPARED``, ``V4L2_BUF_FLAG_QUEUED`` and
-``V4L2_BUF_FLAG_DONE`` flags will be valid. The ``memory`` field will be
-set to the current I/O method. For the single-planar API, the
-``m.offset`` contains the offset of the buffer from the start of the
-device memory, the ``length`` field its size. For the multi-planar API,
-fields ``m.mem_offset`` and ``length`` in the ``m.planes`` array
-elements will be used instead and the ``length`` field of struct
-:c:type:`v4l2_buffer` is set to the number of filled-in
-array elements. The driver may or may not set the remaining fields and
-flags, they are meaningless in this context.
-
-The struct :c:type:`v4l2_buffer` structure is specified in
-:ref:`buffer`.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-===========
-
-All V4L2 devices support the ``VIDIOC_QUERYCAP`` ioctl. It is used to

-information about driver and hardware capabilities. The ioctl takes a
-pointer to a struct :c:type:`v4l2_capability` which is
-filled by the driver. When the driver is not compatible with this

-    * - __u8
-      - ``driver``\ [16]
-      - Name of the driver, a unique NUL-terminated ASCII string. For
-	example: "bttv". Driver specific applications can use this
-	information to verify the driver identity. It is also useful to
-	work around known bugs, or to identify drivers in error reports.
-
-	Storing strings in fixed sized arrays is bad practice but
-	unavoidable here. Drivers and applications should take precautions
-	to never read or write beyond the end of the array and to make
-	sure the strings are properly NUL-terminated.
-    * - __u8
-      - ``card``\ [32]
-      - Name of the device, a NUL-terminated UTF-8 string. For example:
-	"Yoyodyne TV/FM". One driver may support different brands or
-	models of video hardware. This information is intended for users,
-	for example in a menu of available devices. Since multiple TV
-	cards of the same brand may be installed which are supported by
-	the same driver, this name should be combined with the character
-	device file name (e. g. ``/dev/video2``) or the ``bus_info``
-	string to avoid ambiguities.
-    * - __u8
-      - ``bus_info``\ [32]
-      - Location of the device in the system, a NUL-terminated ASCII
-	string. For example: "PCI:0000:05:06.0". This information is
-	intended for users, to distinguish multiple identical devices. If
-	no such information is available the field must simply count the
-	devices controlled by the driver ("platform:vivi-000"). The
-	bus_info must start with "PCI:" for PCI boards, "PCIe:" for PCI
-	Express boards, "usb-" for USB devices, "I2C:" for i2c devices,
-	"ISA:" for ISA devices, "parport" for parallel port devices and
-	"platform:" for platform devices.
-    * - __u32
-      - ``version``
-      - Version number of the driver.
-
-	Starting with kernel 3.1, the version reported is provided by the
-	V4L2 subsystem following the kernel numbering scheme. However, it
-	may not always return the same version as the kernel if, for
-	example, a stable or distribution-modified kernel uses the V4L2
-	stack from a newer kernel.
-
-	The version number is formatted using the ``KERNEL_VERSION()``
-	macro. For example if the media stack corresponds to the V4L2
-	version shipped with Kernel 4.14, it would be equivalent to:
-    * - :cspan:`2`
-
-	``#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))``
-
-	``__u32 version = KERNEL_VERSION(4, 14, 0);``
-
-	``printf ("Version: %u.%u.%u\\n",``
-
-	``(version >> 16) & 0xFF, (version >> 8) & 0xFF, version & 0xFF);``
-    * - __u32
-      - ``capabilities``
-      - Available capabilities of the physical device as a whole, see
-	:ref:`device-capabilities`. The same physical device can export
-	multiple devices in /dev (e.g. /dev/videoX, /dev/vbiY and
-	/dev/radioZ). The ``capabilities`` field should contain a union of
-	all capabilities available around the several V4L2 devices
-	exported to userspace. For all those devices the ``capabilities``
-	field returns the same set of capabilities. This allows
-	applications to open just one of the devices (typically the video
-	device) and discover whether video, vbi and/or radio are also
-	supported.
-    * - __u32
-      - ``device_caps``
-      - Device capabilities of the opened device, see
-	:ref:`device-capabilities`. Should contain the available
-	capabilities of that specific device node. So, for example,
-	``device_caps`` of a radio device will only contain radio related
-	capabilities and no video or vbi capabilities. This field is only
-	set if the ``capabilities`` field contains the
-	``V4L2_CAP_DEVICE_CAPS`` capability. Only the ``capabilities``
-	field can have the ``V4L2_CAP_DEVICE_CAPS`` capability,
-	``device_caps`` will never set ``V4L2_CAP_DEVICE_CAPS``.
-    * - __u32
-      - ``reserved``\ [3]
-      - Reserved for future extensions. Drivers must set this array to
-	zero.

-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set
-appropriately. The generic error codes are described at the
-:ref:`Generic Error Codes <gen-errors>` chapter.
-
-.. [#f1]
-   The struct :c:type:`v4l2_framebuffer` lacks an
-   enum :c:type:`v4l2_buf_type` field, therefore the
-   type of overlay is implied by the driver capabilities.

-Description
-===========
-
-To query the attributes of a control applications set the ``id`` field
-of a struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` and call the
-``VIDIOC_QUERYCTRL`` ioctl with a pointer to this structure. The driver
-fills the rest of the structure or returns an ``EINVAL`` error code when the
-``id`` is invalid.
-
-It is possible to enumerate controls by calling ``VIDIOC_QUERYCTRL``
-with successive ``id`` values starting from ``V4L2_CID_BASE`` up to and
-exclusive ``V4L2_CID_LASTP1``. Drivers may return ``EINVAL`` if a control in
-this range is not supported. Further applications can enumerate private
-controls, which are not defined in this specification, by starting at
-``V4L2_CID_PRIVATE_BASE`` and incrementing ``id`` until the driver
-returns ``EINVAL``.
-
-In both cases, when the driver sets the ``V4L2_CTRL_FLAG_DISABLED`` flag
-in the ``flags`` field this control is permanently disabled and should
-be ignored by the application. [#f1]_
-
-When the application ORs ``id`` with ``V4L2_CTRL_FLAG_NEXT_CTRL`` the
-driver returns the next supported non-compound control, or ``EINVAL`` if
-there is none. In addition, the ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` flag
-can be specified to enumerate all compound controls (i.e. controls with
-type ≥ ``V4L2_CTRL_COMPOUND_TYPES`` and/or array control, in other words
-controls that contain more than one value). Specify both
-``V4L2_CTRL_FLAG_NEXT_CTRL`` and ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` in
-order to enumerate all controls, compound or not. Drivers which do not
-support these flags yet always return ``EINVAL``.
-
-The ``VIDIOC_QUERY_EXT_CTRL`` ioctl was introduced in order to better
-support controls that can use compound types, and to expose additional
-control information that cannot be returned in struct
-:ref:`v4l2_queryctrl <v4l2-queryctrl>` since that structure is full.
-
-``VIDIOC_QUERY_EXT_CTRL`` is used in the same way as
-``VIDIOC_QUERYCTRL``, except that the ``reserved`` array must be zeroed
-as well.
-
-Additional information is required for menu controls: the names of the
-menu items. To query them applications set the ``id`` and ``index``
-fields of struct :ref:`v4l2_querymenu <v4l2-querymenu>` and call the
-``VIDIOC_QUERYMENU`` ioctl with a pointer to this structure. The driver
-fills the rest of the structure or returns an ``EINVAL`` error code when the
-``id`` or ``index`` is invalid. Menu items are enumerated by calling
-``VIDIOC_QUERYMENU`` with successive ``index`` values from struct
-:ref:`v4l2_queryctrl <v4l2-queryctrl>` ``minimum`` to ``maximum``,
-inclusive.
-
-.. note::
-
-   It is possible for ``VIDIOC_QUERYMENU`` to return
-   an ``EINVAL`` error code for some indices between ``minimum`` and
-   ``maximum``. In that case that particular menu item is not supported by
-   this driver. Also note that the ``minimum`` value is not necessarily 0.
-
-See also the examples in :ref:`control`.

-    * - ``V4L2_CTRL_FLAG_GRABBED``
-      - 0x0002
-      - This control is temporarily unchangeable, for example because

-	Such controls may be displayed specially in a user interface.
-	Attempts to change the control may result in an ``EBUSY`` error code.
-    * - ``V4L2_CTRL_FLAG_READ_ONLY``

-      - This control is permanently readable only. Any attempt to change
-	the control will result in an ``EINVAL`` error code.
-    * - ``V4L2_CTRL_FLAG_UPDATE``
-      - 0x0008

-    * - ``V4L2_CTRL_FLAG_INACTIVE``
-      - 0x0010
-      - This control is not applicable to the current configuration and

-    * - ``V4L2_CTRL_FLAG_WRITE_ONLY``
-      - 0x0040
-      - This control is permanently writable only. Any attempt to read the
-	control will result in an ``EACCES`` error code error code. This flag
-	is typically present for relative controls or action controls
-	where writing a value will cause the device to carry out a given
-	action (e. g. motor control) but no meaningful value can be
-	returned.
-    * - ``V4L2_CTRL_FLAG_VOLATILE``
-      - 0x0080
-      - This control is volatile, which means that the value of the
-	control changes continuously. A typical example would be the
-	current gain value if the device is in auto-gain mode. In such a
-	case the hardware calculates the gain value based on the lighting
-	conditions which can change over time.
-
-	.. note::
-
-	   Setting a new value for a volatile control will be ignored
-	   unless
-	   :ref:`V4L2_CTRL_FLAG_EXECUTE_ON_WRITE <FLAG_EXECUTE_ON_WRITE>`
-	   is also set.
-	   Setting a new value for a volatile control will *never* trigger a

-    * - ``V4L2_CTRL_FLAG_HAS_PAYLOAD``
-      - 0x0100
-      - This control has a pointer type, so its value has to be accessed
-	using one of the pointer fields of struct
-	:c:type:`v4l2_ext_control`. This flag is set
-	for controls that are an array, string, or have a compound type.
-	In all cases you have to set a pointer to memory containing the
-	payload of the control.
-    * .. _FLAG_EXECUTE_ON_WRITE:
-
-      - ``V4L2_CTRL_FLAG_EXECUTE_ON_WRITE``
-      - 0x0200
-      - The value provided to the control will be propagated to the driver
-	even if it remains constant. This is required when the control
-	represents an action on the hardware. For example: clearing an
-	error flag or triggering the flash. All the controls of the type
-	``V4L2_CTRL_TYPE_BUTTON`` have this flag set.
-    * .. _FLAG_MODIFY_LAYOUT:
-
-      - ``V4L2_CTRL_FLAG_MODIFY_LAYOUT``
-      - 0x0400
-      - Changing this control value may modify the layout of the
-        buffer (for video devices) or the media bus format (for sub-devices).
-
-	A typical example would be the ``V4L2_CID_ROTATE`` control.
-
-	Note that typically controls with this flag will also set the
-	``V4L2_CTRL_FLAG_GRABBED`` flag when buffers are allocated or
-	streaming is in progress since most drivers do not support changing
-	the format in that case.

-    An attempt was made to read a write-only control.
-
-.. [#f1]
-   ``V4L2_CTRL_FLAG_DISABLED`` was intended for two purposes: Drivers
-   can skip predefined controls not supported by the hardware (although
-   returning ``EINVAL`` would do as well), or disable predefined and private
-   controls after hardware detection without the trouble of reordering
-   control arrays and indices (``EINVAL`` cannot be used to skip private
-   controls because it would prematurely end the enumeration).

-Description
-===========
-
-The hardware may be able to detect the current video standard

-pointer to a :ref:`v4l2_std_id <v4l2-std-id>` type. The driver
-stores here a set of candidates, this can be a single flag or a set of
-supported standards if for example the hardware can only distinguish
-between 50 and 60 Hz systems. If no signal was detected, then the driver
-will return V4L2_STD_UNKNOWN. When detection is not possible or fails,
-the set must contain all standards supported by the current video input
-or output.
-
-.. note::
-
-   Drivers shall *not* switch the video standard
-   automatically if a new video standard is detected. Instead, drivers
-   should send the ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support
-   this) and expect that userspace will take action by calling
-   :ref:`VIDIOC_QUERYSTD`. The reason is that a new video standard can mean
-   different buffer sizes as well, and you cannot change buffer sizes on
-   the fly. In general, applications that receive the Source Change event
-   will have to call :ref:`VIDIOC_QUERYSTD`, and if the detected video
-   standard is valid they will have to stop streaming, set the new
-   standard, allocate new buffers and start streaming again.

-VIDIOC_REQBUFS - Initiate Memory Mapping, User Pointer I/O or DMA buffer I/O
-
-
-Synopsis
-========
-
-.. c:function:: int ioctl( int fd, VIDIOC_REQBUFS, struct v4l2_requestbuffers *argp )
-    :name: VIDIOC_REQBUFS
-
-
-Arguments
-=========
-
-``fd``
-    File descriptor returned by :ref:`open() <func-open>`.
-
-``argp``
-    Pointer to struct :c:type:`v4l2_requestbuffers`.
-
-Description
-===========
-
-This ioctl is used to initiate :ref:`memory mapped <mmap>`,
-:ref:`user pointer <userp>` or :ref:`DMABUF <dmabuf>` based I/O.
-Memory mapped buffers are located in device memory and must be allocated
-with this ioctl before they can be mapped into the application's address
-space. User buffers are allocated by applications themselves, and this
-ioctl is merely used to switch the driver into user pointer I/O mode and
-to setup some internal structures. Similarly, DMABUF buffers are
-allocated by applications through a device driver, and this ioctl only
-configures the driver into DMABUF I/O mode without performing any direct
-allocation.
-
-To allocate device buffers applications initialize all fields of the
-struct :c:type:`v4l2_requestbuffers` structure. They set the ``type``
-field to the respective stream or buffer type, the ``count`` field to
-the desired number of buffers, ``memory`` must be set to the requested
-I/O method and the ``reserved`` array must be zeroed. When the ioctl is
-called with a pointer to this structure the driver will attempt to
-allocate the requested number of buffers and it stores the actual number
-allocated in the ``count`` field. It can be smaller than the number
-requested, even zero, when the driver runs out of free memory. A larger
-number is also possible when the driver requires more buffers to
-function correctly. For example video output requires at least two
-buffers, one displayed and one filled by the application.
-
-When the I/O method is not supported the ioctl returns an ``EINVAL`` error
-code.
-
-Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of
-buffers. Note that if any buffers are still mapped or exported via DMABUF,
-then :ref:`VIDIOC_REQBUFS` can only succeed if the
-``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` capability is set. Otherwise
-:ref:`VIDIOC_REQBUFS` will return the ``EBUSY`` error code.
-If ``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` is set, then these buffers are
-orphaned and will be freed when they are unmapped or when the exported DMABUF
-fds are closed. A ``count`` value of zero frees or orphans all buffers, after
-aborting or finishing any DMA in progress, an implicit
-:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`.

-Description
-===========
-
-Start a hardware frequency seek from the current frequency. To do this
-applications initialize the ``tuner``, ``type``, ``seek_upward``,
-``wrap_around``, ``spacing``, ``rangelow`` and ``rangehigh`` fields, and
-zero out the ``reserved`` array of a struct
-:c:type:`v4l2_hw_freq_seek` and call the
-``VIDIOC_S_HW_FREQ_SEEK`` ioctl with a pointer to this structure.
-
-The ``rangelow`` and ``rangehigh`` fields can be set to a non-zero value
-to tell the driver to search a specific band. If the struct
-:c:type:`v4l2_tuner` ``capability`` field has the
-``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag set, these values must fall
-within one of the bands returned by
-:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
-``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag is not set, then these values
-must exactly match those of one of the bands returned by
-:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
-current frequency of the tuner does not fall within the selected band it
-will be clamped to fit in the band before the seek is started.
-
-If an error is returned, then the original frequency will be restored.
-
-This ioctl is supported if the ``V4L2_CAP_HW_FREQ_SEEK`` capability is

-:ref:`DMABUF <dmabuf>`) I/O.
-
-Capture hardware is disabled and no input buffers are filled (if there
-are any empty buffers in the incoming queue) until ``VIDIOC_STREAMON``
-has been called. Output hardware is disabled and no video signal is
-produced until ``VIDIOC_STREAMON`` has been called. The ioctl will
-succeed when at least one output buffer is in the incoming queue.
-
-Memory-to-memory devices will not start until ``VIDIOC_STREAMON`` has
-been called for both the capture and output stream types.
-
-If ``VIDIOC_STREAMON`` fails then any already queued buffers will remain
-queued.
-
-The ``VIDIOC_STREAMOFF`` ioctl, apart of aborting or finishing any DMA
-in progress, unlocks any user pointer buffers locked in physical memory,
-and it removes all buffers from the incoming and outgoing queues. That
-means all images captured but not dequeued yet will be lost, likewise
-all images enqueued for output but not transmitted yet. I/O returns to
-the same state as after calling
-:ref:`VIDIOC_REQBUFS` and can be restarted
-accordingly.
-
-If buffers have been queued with :ref:`VIDIOC_QBUF` and
-``VIDIOC_STREAMOFF`` is called without ever having called
-``VIDIOC_STREAMON``, then those queued buffers will also be removed from
-the incoming queue and all are returned to the same state as after
-calling :ref:`VIDIOC_REQBUFS` and can be restarted
-accordingly.
-
-Both ioctls take a pointer to an integer, the desired buffer or stream
-type. This is the same as struct
-:c:type:`v4l2_requestbuffers` ``type``.
-
-If ``VIDIOC_STREAMON`` is called when streaming is already in progress,
-or if ``VIDIOC_STREAMOFF`` is called when streaming is already stopped,
-then 0 is returned. Nothing happens in the case of ``VIDIOC_STREAMON``,
-but ``VIDIOC_STREAMOFF`` will return queued buffers to their starting
-state as mentioned above.
-
-.. note::
-
-   Applications can be preempted for unknown periods right before
-   or after the ``VIDIOC_STREAMON`` or ``VIDIOC_STREAMOFF`` calls, there is
-   no notion of starting or stopping "now". Buffer timestamps can be used
-   to synchronize with other events.
-
-
-Return Value
-============
-
-On success 0 is returned, on error -1 and the ``errno`` variable is set

-
-
-Description
-===========
-
-This ioctl lets applications enumerate available frame intervals on a
-given sub-device pad. Frame intervals only makes sense for sub-devices
-that can control the frame period on their own. This includes, for
-instance, image sensors and TV tuners.
-
-For the common use case of image sensors, the frame intervals available
-on the sub-device output pad depend on the frame format and size on the
-same pad. Applications must thus specify the desired format and size
-when enumerating frame intervals.
-
-To enumerate frame intervals applications initialize the ``index``,
-``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
-:c:type:`v4l2_subdev_frame_interval_enum`
-and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
-to this structure. Drivers fill the rest of the structure or return an
-EINVAL error code if one of the input fields is invalid. All frame
-intervals are enumerable by beginning at index zero and incrementing by
-one until ``EINVAL`` is returned.
-
-Available frame intervals may depend on the current 'try' formats at
-other pads of the sub-device, as well as on the current active links.
-See :ref:`VIDIOC_SUBDEV_G_FMT` for more
-information about the try formats.
-
-Sub-devices that support the frame interval enumeration ioctl should
-implemented it on a single pad only. Its behaviour when supported on
-multiple pads of the same sub-device is not defined.

-
-
-Description
-===========
-
-This ioctl allows applications to enumerate all frame sizes supported by
-a sub-device on the given pad for the given media bus format. Supported
-formats can be retrieved with the
-:ref:`VIDIOC_SUBDEV_ENUM_MBUS_CODE`
-ioctl.
-
-To enumerate frame sizes applications initialize the ``pad``, ``which``
-, ``code`` and ``index`` fields of the struct
-:c:type:`v4l2_subdev_mbus_code_enum` and
-call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_SIZE` ioctl with a pointer to the
-structure. Drivers fill the minimum and maximum frame sizes or return an
-EINVAL error code if one of the input parameters is invalid.
-
-Sub-devices that only support discrete frame sizes (such as most
-sensors) will return one or more frame sizes with identical minimum and
-maximum values.
-
-Not all possible sizes in given [minimum, maximum] ranges need to be
-supported. For instance, a scaler that uses a fixed-point scaling ratio
-might not be able to produce every frame size between the minimum and
-maximum values. Applications must use the
-:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl to try the
-sub-device for an exact supported frame size.
-
-Available frame sizes may depend on the current 'try' formats at other
-pads of the sub-device, as well as on the current active links and the
-current values of V4L2 controls. See
-:ref:`VIDIOC_SUBDEV_G_FMT` for more

-===========
-
-.. note::
-
-    This is an :ref:`obsolete` interface and may be removed
-    in the future. It is superseded by
-    :ref:`the selection API <VIDIOC_SUBDEV_G_SELECTION>`.
-
-To retrieve the current crop rectangle applications set the ``pad``
-field of a struct :c:type:`v4l2_subdev_crop` to the
-desired pad number as reported by the media API and the ``which`` field
-to ``V4L2_SUBDEV_FORMAT_ACTIVE``. They then call the
-``VIDIOC_SUBDEV_G_CROP`` ioctl with a pointer to this structure. The
-driver fills the members of the ``rect`` field or returns ``EINVAL`` error
-code if the input arguments are invalid, or if cropping is not supported
-on the given pad.
-
-To change the current crop rectangle applications set both the ``pad``
-and ``which`` fields and all members of the ``rect`` field. They then
-call the ``VIDIOC_SUBDEV_S_CROP`` ioctl with a pointer to this
-structure. The driver verifies the requested crop rectangle, adjusts it
-based on the hardware capabilities and configures the device. Upon
-return the struct :c:type:`v4l2_subdev_crop`
-contains the current format as would be returned by a
-``VIDIOC_SUBDEV_G_CROP`` call.
-
-Applications can query the device capabilities by setting the ``which``
-to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' crop rectangles are not
-applied to the device by the driver, but are mangled exactly as active
-crop rectangles and stored in the sub-device file handle. Two
-applications querying the same sub-device would thus not interact with
-each other.
-
-Drivers must not return an error solely because the requested crop
-rectangle doesn't match the device capabilities. They must instead
-modify the rectangle to match what the hardware can provide. The
-modified format should be as close as possible to the original request.

-format as would be returned by a ``VIDIOC_SUBDEV_G_FMT`` call.
-
-Applications can query the device capabilities by setting the ``which``
-to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' formats are not applied
-to the device by the driver, but are changed exactly as active formats
-and stored in the sub-device file handle. Two applications querying the
-same sub-device would thus not interact with each other.
-
-For instance, to try a format at the output pad of a sub-device,
-applications would first set the try format at the sub-device input with
-the ``VIDIOC_SUBDEV_S_FMT`` ioctl. They would then either retrieve the
-default format at the output pad with the ``VIDIOC_SUBDEV_G_FMT`` ioctl,
-or set the desired output pad format with the ``VIDIOC_SUBDEV_S_FMT``
-ioctl and check the returned value.
-
-Try formats do not depend on active formats, but can depend on the
-current links configuration or sub-device controls value. For instance,
-a low-pass noise filter might crop pixels at the frame boundaries,
-modifying its output frame size.
-
-Drivers must not return an error solely because the requested format
-doesn't match the device capabilities. They must instead modify the
-format to match what the hardware can provide. The modified format
-should be as close as possible to the original request.

-
-
-Description
-===========
-
-These ioctls are used to get and set the frame interval at specific
-subdev pads in the image pipeline. The frame interval only makes sense
-for sub-devices that can control the frame period on their own. This
-includes, for instance, image sensors and TV tuners. Sub-devices that
-don't support frame intervals must not implement these ioctls.
-
-To retrieve the current frame interval applications set the ``pad``
-field of a struct
-:c:type:`v4l2_subdev_frame_interval` to
-the desired pad number as reported by the media controller API. When
-they call the ``VIDIOC_SUBDEV_G_FRAME_INTERVAL`` ioctl with a pointer to
-this structure the driver fills the members of the ``interval`` field.
-
-To change the current frame interval applications set both the ``pad``
-field and all members of the ``interval`` field. When they call the
-``VIDIOC_SUBDEV_S_FRAME_INTERVAL`` ioctl with a pointer to this
-structure the driver verifies the requested interval, adjusts it based
-on the hardware capabilities and configures the device. Upon return the
-struct
-:c:type:`v4l2_subdev_frame_interval`
-contains the current frame interval as would be returned by a
-``VIDIOC_SUBDEV_G_FRAME_INTERVAL`` call.
-
-Drivers must not return an error solely because the requested interval
-doesn't match the device capabilities. They must instead modify the
-interval to match what the hardware can provide. The modified interval
-should be as close as possible to the original request.
-
-Changing the frame interval shall never change the format. Changing the
-format, on the other hand, may change the frame interval.
-
-Sub-devices that support the frame interval ioctls should implement them
-on a single pad only. Their behaviour when supported on multiple pads of
-the same sub-device is not defined.

-
-Description
-===========
-
-The selections are used to configure various image processing
-functionality performed by the subdevs which affect the image size. This
-currently includes cropping, scaling and composition.
-
-The selection API replaces
-:ref:`the old subdev crop API <VIDIOC_SUBDEV_G_CROP>`. All the
-function of the crop API, and more, are supported by the selections API.
-
-See :ref:`subdev` for more information on how each selection target
-affects the image processing pipeline inside the subdevice.
-
-
-Types of selection targets
---------------------------
-
-There are two types of selection targets: actual and bounds. The actual
-targets are the targets which configure the hardware. The BOUNDS target
-will return a rectangle that contain all possible actual rectangles.
-
-
-Discovering supported features
-------------------------------
-
-To discover which targets are supported, the user can perform
-``VIDIOC_SUBDEV_G_SELECTION`` on them. Any unsupported target will
-return ``EINVAL``.
-
-Selection targets and flags are documented in

-YUV Formats
-***********
-
-YUV is the format native to TV broadcast and composite video signals. It
-separates the brightness information (Y) from the color information (U
-and V or Cb and Cr). The color information consists of red and blue
-*color difference* signals, this way the green component can be
-reconstructed by subtracting from the brightness component. See
-:ref:`colorspaces` for conversion examples. YUV was chosen because
-early television would only transmit brightness information. To add
-color in a way compatible with existing receivers a new signal carrier
-was added to transmit the color difference signals. Secondary in the YUV
-format the U and V components usually have lower resolution than the Y
-component. This is an analog video compression technique taking
-advantage of a property of the human visual system, being more sensitive
-to brightness information.

+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <sys/ioctl.h>
+
+
+.. c:function:: int ioctl( int fd, int request, void *argp )
+   :name: cec-ioctl
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``request``
+    CEC ioctl request code as defined in the cec.h header file, for
+    example :ref:`CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`.
+
+``argp``
+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+The :c:func:`ioctl() <cec-ioctl>` function manipulates cec device parameters. The
+argument ``fd`` must be an open file descriptor.
+
+The ioctl ``request`` code specifies the cec function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying cec ioctl requests and
+their parameters are located in the cec.h header file. All cec ioctl
+requests, their respective function and parameters are specified in
+:ref:`cec-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Request-specific error codes are listed in the individual requests
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+
+.. c:function:: int open( const char *device_name, int flags )
+   :name: cec-open

+
+Arguments
+=========
+
+``device_name``
+    Device to be opened.
+
+``flags``
+    Open flags. Access mode must be ``O_RDWR``.
+
+    When the ``O_NONBLOCK`` flag is given, the
+    :ref:`CEC_RECEIVE <CEC_RECEIVE>` and :ref:`CEC_DQEVENT <CEC_DQEVENT>` ioctls
+    will return the ``EAGAIN`` error code when no message or event is available, and

+    all return 0.
+
+    Other flags have no effect.
+
+
+Description
+===========
+
+To open a cec device applications call :c:func:`open() <cec-open>` with the
+desired device name. The function has no side effects; the device
+configuration remain unchanged.
+
+When the device is opened in read-only mode, attempts to modify its
+configuration will result in an error, and ``errno`` will be set to
+EBADF.
+
+
+Return Value
+============
+
+:c:func:`open() <cec-open>` returns the new file descriptor on success. On error,
+-1 is returned, and ``errno`` is set appropriately. Possible error codes
+include:
+
+``EACCES``
+    The requested access to the file is not allowed.
+
+``EMFILE``
+    The process already has the maximum number of files open.
+
+``ENFILE``
+    The system limit on the total number of open files has been reached.
+
+``ENOMEM``
+    Insufficient kernel memory was available.
+
+``ENXIO``
+    No device corresponding to this device special file exists.

+
+    #include <sys/poll.h>
+
+
+.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )

+
+Arguments
+=========
+
+``ufds``
+   List of FD events to be watched
+
+``nfds``
+   Number of FD events at the \*ufds array
+
+``timeout``
+   Timeout to wait for events
+
+
+Description
+===========
+
+With the :c:func:`poll() <cec-poll>` function applications can wait for CEC
+events.
+
+On success :c:func:`poll() <cec-poll>` returns the number of file descriptors
+that have been selected (that is, file descriptors for which the
+``revents`` field of the respective struct :c:type:`pollfd`
+is non-zero). CEC devices set the ``POLLIN`` and ``POLLRDNORM`` flags in
+the ``revents`` field if there are messages in the receive queue. If the
+transmit queue has room for new messages, the ``POLLOUT`` and
+``POLLWRNORM`` flags are set. If there are events in the event queue,
+then the ``POLLPRI`` flag is set. When the function times out it returns
+a value of zero, on failure it returns -1 and the ``errno`` variable is
+set appropriately.
+
+For more details see the :c:func:`poll() <cec-poll>` manual page.
+
+
+Return Value
+============
+
+On success, :c:func:`poll() <cec-poll>` returns the number structures which have
+non-zero ``revents`` fields, or zero if the call timed out. On error -1
+is returned, and the ``errno`` variable is set appropriately:
+
+``EBADF``
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+``EFAULT``
+    ``ufds`` references an inaccessible memory area.
+
+``EINTR``
+    The call was interrupted by a signal.
+
+``EINVAL``
+    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
+    ``getrlimit()`` to obtain this value.

+
+Introduction
+============
+
+HDMI connectors provide a single pin for use by the Consumer Electronics
+Control protocol. This protocol allows different devices connected by an
+HDMI cable to communicate. The protocol for CEC version 1.4 is defined
+in supplements 1 (CEC) and 2 (HEAC or HDMI Ethernet and Audio Return
+Channel) of the HDMI 1.4a (:ref:`hdmi`) specification and the
+extensions added to CEC version 2.0 are defined in chapter 11 of the
+HDMI 2.0 (:ref:`hdmi2`) specification.
+
+The bitrate is very slow (effectively no more than 36 bytes per second)
+and is based on the ancient AV.link protocol used in old SCART
+connectors. The protocol closely resembles a crazy Rube Goldberg
+contraption and is an unholy mix of low and high level messages. Some
+messages, especially those part of the HEAC protocol layered on top of
+CEC, need to be handled by the kernel, others can be handled either by
+the kernel or by userspace.
+
+In addition, CEC can be implemented in HDMI receivers, transmitters and
+in USB devices that have an HDMI input and an HDMI output and that
+control just the CEC pin.
+
+Drivers that support CEC will create a CEC device node (/dev/cecX) to
+give userspace access to the CEC adapter. The
+:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.
+
+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ package. It
+provides three tools to handle CEC:
+
+- cec-ctl: the Swiss army knife of CEC. Allows you to configure, transmit
+  and monitor CEC messages.
+
+- cec-compliance: does a CEC compliance test of a remote CEC device to
+  determine how compliant the CEC implementation is.
+
+- cec-follower: emulates a CEC follower.

+
+All cec devices must support :ref:`ioctl CEC_ADAP_G_CAPS <CEC_ADAP_G_CAPS>`. To query

+	this capability isn't set, then setting the physical address is
+	handled by the kernel whenever the EDID is set (for an HDMI
+	receiver) or read (for an HDMI transmitter).

+
+      - ``CEC_CAP_LOG_ADDRS``

+	this.
+    * .. _`CEC-CAP-TRANSMIT`:
+
+      - ``CEC_CAP_TRANSMIT``
+      - 0x00000004
+      - Userspace can transmit CEC messages by calling
+	:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. This implies that
+	userspace can be a follower as well, since being able to transmit
+	messages is a prerequisite of becoming a follower. If this
+	capability isn't set, then the kernel will handle all CEC
+	transmits and process all CEC messages it receives.

+
+      - ``CEC_CAP_NEEDS_HPD``
+      - 0x00000040

+   :name: CEC_ADAP_S_LOG_ADDRS
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+    Pointer to struct :c:type:`cec_log_addrs`.
+
+Description
+===========
+
+To query the current CEC logical addresses, applications call
+:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
+struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.
+
+To set new logical addresses, applications fill in
+struct :c:type:`cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is
+returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+can only be called by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear existing logical addresses set ``num_log_addrs`` to 0. All other fields
+will be ignored in that case. The adapter will go to the unconfigured state and the
+``cec_version``, ``vendor_id`` and ``osd_name`` fields are all reset to their default
+values (CEC version 2.0, no vendor ID and an empty OSD name).
+
+If the physical address is valid (see :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>`),
+then this ioctl will block until all requested logical
+addresses have been claimed. If the file descriptor is in non-blocking mode then it will
+not wait for the logical addresses to be claimed, instead it just returns 0.
+
+A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the
+logical addresses are claimed or cleared.
+
+Attempting to call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` when
+logical address types are already defined will return with error ``EBUSY``.

+
+    * - __u8
+      - ``log_addr[CEC_MAX_LOG_ADDRS]``
+      - The actual logical addresses that were claimed. This is set by the
+	driver. If no logical address could be claimed, then it is set to
+	``CEC_LOG_ADDR_INVALID``. If this adapter is Unregistered, then
+	``log_addr[0]`` is set to 0xf and all others to
+	``CEC_LOG_ADDR_INVALID``.
+    * - __u16
+      - ``log_addr_mask``
+      - The bitmask of all logical addresses this adapter has claimed. If
+	this adapter is Unregistered then ``log_addr_mask`` sets bit 15
+	and clears all other bits. If this adapter is not configured at
+	all, then ``log_addr_mask`` is set to 0. Set by the driver.
+    * - __u8
+      - ``cec_version``
+      - The CEC version that this adapter shall use. See
+	:ref:`cec-versions`. Used to implement the
+	``CEC_MSG_CEC_VERSION`` and ``CEC_MSG_REPORT_FEATURES`` messages.
+	Note that :ref:`CEC_OP_CEC_VERSION_1_3A <CEC-OP-CEC-VERSION-1-3A>` is not allowed by the CEC
+	framework.
+    * - __u8
+      - ``num_log_addrs``
+      - Number of logical addresses to set up. Must be ≤
+	``available_log_addrs`` as returned by
+	:ref:`CEC_ADAP_G_CAPS`. All arrays in
+	this structure are only filled up to index
+	``available_log_addrs``-1. The remaining array elements will be
+	ignored. Note that the CEC 2.0 standard allows for a maximum of 2
+	logical addresses, although some hardware has support for more.
+	``CEC_MAX_LOG_ADDRS`` is 4. The driver will return the actual
+	number of logical addresses it could claim, which may be less than
+	what was requested. If this field is set to 0, then the CEC
+	adapter shall clear all claimed logical addresses and all other
+	fields will be ignored.
+    * - __u32
+      - ``vendor_id``
+      - The vendor ID is a 24-bit number that identifies the specific
+	vendor or entity. Based on this ID vendor specific commands may be
+	defined. If you do not want a vendor ID then set it to
+	``CEC_VENDOR_ID_NONE``.
+    * - __u32
+      - ``flags``
+      - Flags. See :ref:`cec-log-addrs-flags` for a list of available flags.
+    * - char
+      - ``osd_name[15]``
+      - The On-Screen Display name as is returned by the
+	``CEC_MSG_SET_OSD_NAME`` message.
+    * - __u8
+      - ``primary_device_type[CEC_MAX_LOG_ADDRS]``
+      - Primary device type for each logical address. See
+	:ref:`cec-prim-dev-types` for possible types.
+    * - __u8
+      - ``log_addr_type[CEC_MAX_LOG_ADDRS]``
+      - Logical address types. See :ref:`cec-log-addr-types` for
+	possible types. The driver will update this with the actual
+	logical address type that it claimed (e.g. it may have to fallback
+	to :ref:`CEC_LOG_ADDR_TYPE_UNREGISTERED <CEC-LOG-ADDR-TYPE-UNREGISTERED>`).
+    * - __u8
+      - ``all_device_types[CEC_MAX_LOG_ADDRS]``
+      - CEC 2.0 specific: the bit mask of all device types. See
+	:ref:`cec-all-dev-types-flags`. It is used in the CEC 2.0
+	``CEC_MSG_REPORT_FEATURES`` message. For CEC 1.4 you can either leave
+	this field to 0, or fill it in according to the CEC 2.0 guidelines to
+	give the CEC framework more information about the device type, even
+	though the framework won't use it directly in the CEC message.
+    * - __u8
+      - ``features[CEC_MAX_LOG_ADDRS][12]``
+      - Features for each logical address. It is used in the CEC 2.0
+	``CEC_MSG_REPORT_FEATURES`` message. The 12 bytes include both the
+	RC Profile and the Device Features. For CEC 1.4 you can either leave
+        this field to all 0, or fill it in according to the CEC 2.0 guidelines to
+        give the CEC framework more information about the device type, even
+        though the framework won't use it directly in the CEC message.

+    File descriptor returned by :c:func:`open() <cec-open>`.
+

+    Pointer to the CEC address.
+
+Description
+===========
+
+To query the current physical address applications call
+:ref:`ioctl CEC_ADAP_G_PHYS_ADDR <CEC_ADAP_G_PHYS_ADDR>` with a pointer to a __u16 where the
+driver stores the physical address.
+
+To set a new physical address applications store the physical address in
+a __u16 and call :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` with a pointer to
+this integer. The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` is only available if
+``CEC_CAP_PHYS_ADDR`` is set (the ``ENOTTY`` error code will be returned
+otherwise). The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can only be called
+by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear an existing physical address use ``CEC_PHYS_ADDR_INVALID``.
+The adapter will go to the unconfigured state.
+
+If logical address types have been defined (see :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`),
+then this ioctl will block until all
+requested logical addresses have been claimed. If the file descriptor is in non-blocking mode
+then it will not wait for the logical addresses to be claimed, instead it just returns 0.
+
+A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the physical address
+changes.
+
+The physical address is a 16-bit number where each group of 4 bits
+represent a digit of the physical address a.b.c.d where the most
+significant 4 bits represent 'a'. The CEC root device (usually the TV)
+has address 0.0.0.0. Every device that is hooked up to an input of the
+TV has address a.0.0.0 (where 'a' is ≥ 1), devices hooked up to those in
+turn have addresses a.b.0.0, etc. So a topology of up to 5 devices deep
+is supported. The physical address a device shall use is stored in the
+EDID of the sink.
+
+For example, the EDID for each HDMI input of the TV will have a
+different physical address of the form a.0.0.0 that the sources will
+read out and use as their physical address.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can return the following
+error codes:
+
+ENOTTY
+    The ``CEC_CAP_PHYS_ADDR`` capability wasn't set, so this ioctl is not supported.
+
+EBUSY
+    Another filehandle is in exclusive follower or initiator mode, or the filehandle
+    is in mode ``CEC_MODE_NO_INITIATOR``.
+
+EINVAL
+    The physical address is malformed.

+
+CEC devices can send asynchronous events. These can be retrieved by

+
+``fd``
+    File descriptor returned by :c:func:`open() <cec-open>`.
+
+``argp``
+    Pointer to CEC mode.
+
+Description
+===========
+
+By default any filehandle can use :ref:`CEC_TRANSMIT`, but in order to prevent
+applications from stepping on each others toes it must be possible to
+obtain exclusive access to the CEC adapter. This ioctl sets the
+filehandle to initiator and/or follower mode which can be exclusive
+depending on the chosen mode. The initiator is the filehandle that is
+used to initiate messages, i.e. it commands other CEC devices. The
+follower is the filehandle that receives messages sent to the CEC
+adapter and processes them. The same filehandle can be both initiator
+and follower, or this role can be taken by two different filehandles.
+
+When a CEC message is received, then the CEC framework will decide how
+it will be processed. If the message is a reply to an earlier
+transmitted message, then the reply is sent back to the filehandle that
+is waiting for it. In addition the CEC framework will process it.
+
+If the message is not a reply, then the CEC framework will process it
+first. If there is no follower, then the message is just discarded and a
+feature abort is sent back to the initiator if the framework couldn't
+process it. If there is a follower, then the message is passed on to the
+follower who will use :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` to dequeue
+the new message. The framework expects the follower to make the right
+decisions.
+
+The CEC framework will process core messages unless requested otherwise
+by the follower. The follower can enable the passthrough mode. In that
+case, the CEC framework will pass on most core messages without
+processing them and the follower will have to implement those messages.
+There are some messages that the core will always process, regardless of
+the passthrough mode. See :ref:`cec-core-processing` for details.
+
+If there is no initiator, then any CEC filehandle can use
+:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If there is an exclusive
+initiator then only that initiator can call
+:ref:`CEC_TRANSMIT`. The follower can of course
+always call :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.

+	make any other changes to the CEC adapter.
+    * .. _`CEC-MODE-INITIATOR`:
+
+      - ``CEC_MODE_INITIATOR``
+      - 0x1

+	it can transmit CEC messages and make changes to the CEC adapter,

+      - This is an exclusive follower and only this file descriptor will
+	receive CEC messages for processing. In addition it will put the
+	CEC device into passthrough mode, allowing the exclusive follower
+	to handle most core messages instead of relying on the CEC
+	framework for that. If someone else is already the exclusive
+	follower then an attempt to become one will return the ``EBUSY`` error
+	code. You cannot become a follower if :ref:`CEC_CAP_TRANSMIT <CEC-CAP-TRANSMIT>`

+	otherwise the ``EINVAL`` error code will be returned.
+	This mode requires that the :ref:`CEC_CAP_MONITOR_PIN <CEC-CAP-MONITOR-PIN>`
+	capability is set, otherwise the ``EINVAL`` error code is returned.
+	While in pin monitoring mode this file descriptor can receive the
+	``CEC_EVENT_PIN_CEC_LOW`` and ``CEC_EVENT_PIN_CEC_HIGH`` events to see the
+	low-level CEC pin transitions. This is very useful for debugging.

+	otherwise the ``EINVAL`` error code will be returned.
+	In monitor mode all messages this CEC
+	device transmits and all messages it receives (both broadcast
+	messages and directed messages for one its logical addresses) will
+	be reported. This is very useful for debugging. This is only
+	allowed if the process has the ``CAP_NET_ADMIN`` capability. If

+    Pointer to struct cec_msg.
+
+Description
+===========
+
+To receive a CEC message the application has to fill in the
+``timeout`` field of struct :c:type:`cec_msg` and pass it to
+:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+If the file descriptor is in non-blocking mode and there are no received
+messages pending, then it will return -1 and set errno to the ``EAGAIN``
+error code. If the file descriptor is in blocking mode and ``timeout``
+is non-zero and no message arrived within ``timeout`` milliseconds, then
+it will return -1 and set errno to the ``ETIMEDOUT`` error code.
+
+A received message can be:
+
+1. a message received from another CEC device (the ``sequence`` field will
+   be 0).
+2. the result of an earlier non-blocking transmit (the ``sequence`` field will
+   be non-zero).
+
+To send a CEC message the application has to fill in the struct
+:c:type:`cec_msg` and pass it to :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.
+The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is only available if
+``CEC_CAP_TRANSMIT`` is set. If there is no more room in the transmit
+queue, then it will return -1 and set errno to the ``EBUSY`` error code.
+The transmit queue has enough room for 18 messages (about 1 second worth
+of 2-byte messages). Note that the CEC kernel framework will also reply
+to core messages (see :ref:`cec-core-processing`), so it is not a good
+idea to fully fill up the transmit queue.
+
+If the file descriptor is in non-blocking mode then the transmit will
+return 0 and the result of the transmit will be available via
+:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` once the transmit has finished
+(including waiting for a reply, if requested).
+
+The ``sequence`` field is filled in for every transmit and this can be
+checked against the received messages to find the corresponding transmit
+result.
+
+Normally calling :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` when the physical
+address is invalid (due to e.g. a disconnect) will return ``ENONET``.
+
+However, the CEC specification allows sending messages from 'Unregistered' to
+'TV' when the physical address is invalid since some TVs pull the hotplug detect
+pin of the HDMI connector low when they go into standby, or when switching to
+another input.
+
+When the hotplug detect pin goes low the EDID disappears, and thus the
+physical address, but the cable is still connected and CEC still works.
+In order to detect/wake up the device it is allowed to send poll and 'Image/Text
+View On' messages from initiator 0xf ('Unregistered') to destination 0 ('TV').

+
+    * - __u64
+      - ``tx_ts``
+      - Timestamp in ns of when the last byte of the message was transmitted.
+	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
+	the same clock from userspace use :c:func:`clock_gettime`.
+    * - __u64
+      - ``rx_ts``
+      - Timestamp in ns of when the last byte of the message was received.
+	The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
+	the same clock from userspace use :c:func:`clock_gettime`.
+    * - __u32
+      - ``len``
+      - The length of the message. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in
+	by the application. The driver will fill this in for
+	:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be
+	filled in by the driver with the length of the reply message if ``reply`` was set.
+    * - __u32
+      - ``timeout``
+      - The timeout in milliseconds. This is the time the device will wait
+	for a message to be received before timing out. If it is set to 0,
+	then it will wait indefinitely when it is called by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	If it is 0 and it is called by :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`,
+	then it will be replaced by 1000 if the ``reply`` is non-zero or
+	ignored if ``reply`` is 0.
+    * - __u32
+      - ``sequence``
+      - A non-zero sequence number is automatically assigned by the CEC framework
+	for all transmitted messages. It is used by the CEC framework when it queues
+	the transmit result (when transmit was called in non-blocking mode). This
+	allows the application to associate the received message with the original
+	transmit.
+    * - __u32
+      - ``flags``
+      - Flags. See :ref:`cec-msg-flags` for a list of available flags.
+    * - __u8
+      - ``tx_status``
+      - The status bits of the transmitted message. See
+	:ref:`cec-tx-status` for the possible status values. It is 0 if
+	this message was received, not transmitted.
+    * - __u8
+      - ``msg[16]``
+      - The message payload. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in by the
+	application. The driver will fill this in for :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be filled in by the driver with
+	the payload of the reply message if ``timeout`` was set.
+    * - __u8
+      - ``reply``
+      - Wait until this message is replied. If ``reply`` is 0 and the
+	``timeout`` is 0, then don't wait for a reply but return after
+	transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	The case where ``reply`` is 0 (this is the opcode for the Feature Abort
+	message) and ``timeout`` is non-zero is specifically allowed to make it
+	possible to send a message and wait up to ``timeout`` milliseconds for a
+	Feature Abort reply. In this case ``rx_status`` will either be set
+	to :ref:`CEC_RX_STATUS_TIMEOUT <CEC-RX-STATUS-TIMEOUT>` or
+	:ref:`CEC_RX_STATUS_FEATURE_ABORT <CEC-RX-STATUS-FEATURE-ABORT>`.
+
+	If the transmitter message is ``CEC_MSG_INITIATE_ARC`` then the ``reply``
+	values ``CEC_MSG_REPORT_ARC_INITIATED`` and ``CEC_MSG_REPORT_ARC_TERMINATED``
+	are processed differently: either value will match both possible replies.
+	The reason is that the ``CEC_MSG_INITIATE_ARC`` message is the only CEC
+	message that has two possible replies other than Feature Abort. The
+	``reply`` field will be updated with the actual reply so that it is
+	synchronized with the contents of the received message.
+    * - __u8
+      - ``rx_status``
+      - The status bits of the received message. See
+	:ref:`cec-rx-status` for the possible status values. It is 0 if
+	this message was transmitted, not received, unless this is the
+	reply to a transmitted message. In that case both ``rx_status``
+	and ``tx_status`` are set.
+    * - __u8
+      - ``tx_status``
+      - The status bits of the transmitted message. See
+	:ref:`cec-tx-status` for the possible status values. It is 0 if
+	this message was received, not transmitted.
+    * - __u8
+      - ``tx_arb_lost_cnt``
+      - A counter of the number of transmit attempts that resulted in the
+	Arbitration Lost error. This is only set if the hardware supports
+	this, otherwise it is always 0. This counter is only valid if the
+	:ref:`CEC_TX_STATUS_ARB_LOST <CEC-TX-STATUS-ARB-LOST>` status bit is set.
+    * - __u8
+      - ``tx_nack_cnt``
+      - A counter of the number of transmit attempts that resulted in the
+	Not Acknowledged error. This is only set if the hardware supports
+	this, otherwise it is always 0. This counter is only valid if the
+	:ref:`CEC_TX_STATUS_NACK <CEC-TX-STATUS-NACK>` status bit is set.
+    * - __u8
+      - ``tx_low_drive_cnt``
+      - A counter of the number of transmit attempts that resulted in the
+	Arbitration Lost error. This is only set if the hardware supports
+	this, otherwise it is always 0. This counter is only valid if the
+	:ref:`CEC_TX_STATUS_LOW_DRIVE <CEC-TX-STATUS-LOW-DRIVE>` status bit is set.
+    * - __u8
+      - ``tx_error_cnt``
+      - A counter of the number of transmit errors other than Arbitration
+	Lost or Not Acknowledged. This is only set if the hardware
+	supports this, otherwise it is always 0. This counter is only
+	valid if the :ref:`CEC_TX_STATUS_ERROR <CEC-TX-STATUS-ERROR>` status bit is set.

+	the filehandle that called :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If this
+	flag is set, then the reply is also sent to all followers, if any. If the
+	filehandle that called :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is also a

+	then no validation takes place and the message is transmitted as-is.
+	This is useful when debugging CEC issues.
+	This flag is only allowed if the process has the ``CAP_SYS_RAWIO``
+	capability. If that is not set, then the ``EPERM`` error code is

+    * .. _`CEC-TX-STATUS-LOW-DRIVE`:
+
+      - ``CEC_TX_STATUS_LOW_DRIVE``

+
+      - ``CEC_TX_STATUS_ERROR``

+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+The :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` can return the following
+error codes:
+
+EAGAIN
+    No messages are in the receive queue, and the filehandle is in non-blocking mode.
+
+ETIMEDOUT
+    The ``timeout`` was reached while waiting for a message.
+
+ERESTARTSYS
+    The wait for a message was interrupted (e.g. by Ctrl-C).
+
+The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` can return the following
+error codes:
+
+ENOTTY
+    The ``CEC_CAP_TRANSMIT`` capability wasn't set, so this ioctl is not supported.
+
+EPERM
+    The CEC adapter is not configured, i.e. :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+    has never been called, or ``CEC_MSG_FL_RAW`` was used from a process that
+    did not have the ``CAP_SYS_RAWIO`` capability.
+
+ENONET
+    The CEC adapter is not configured, i.e. :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+    was called, but the physical address is invalid so no logical address was claimed.
+    An exception is made in this case for transmits from initiator 0xf ('Unregistered')
+    to destination 0 ('TV'). In that case the transmit will proceed as usual.
+
+EBUSY
+    Another filehandle is in exclusive follower or initiator mode, or the filehandle
+    is in mode ``CEC_MODE_NO_INITIATOR``. This is also returned if the transmit
+    queue is full.
+
+EINVAL
+    The contents of struct :c:type:`cec_msg` is invalid.
+
+ERESTARTSYS
+    The wait for a successful transmit was interrupted (e.g. by Ctrl-C).

+CEC Pin Framework Error Injection
+=================================
+
+The CEC Pin Framework is a core CEC framework for CEC hardware that only
+has low-level support for the CEC bus. Most hardware today will have
+high-level CEC support where the hardware deals with driving the CEC bus,
+but some older devices aren't that fancy. However, this framework also
+allows you to connect the CEC pin to a GPIO on e.g. a Raspberry Pi and
+you have now made a CEC adapter.
+
+What makes doing this so interesting is that since we have full control
+over the bus it is easy to support error injection. This is ideal to
+test how well CEC adapters can handle error conditions.
+
+Currently only the cec-gpio driver (when the CEC line is directly
+connected to a pull-up GPIO line) and the AllWinner A10/A20 drm driver
+support this framework.
+
+If ``CONFIG_CEC_PIN_ERROR_INJ`` is enabled, then error injection is available
+through debugfs. Specifically, in ``/sys/kernel/debug/cec/cecX/`` there is
+now an ``error-inj`` file.
+
+.. note::
+
+    The error injection commands are not a stable ABI and may change in the
+    future.
+
+With ``cat error-inj`` you can see both the possible commands and the current
+error injection status::
+
+	$ cat /sys/kernel/debug/cec/cec0/error-inj
+	# Clear error injections:
+	#   clear          clear all rx and tx error injections
+	#   rx-clear       clear all rx error injections
+	#   tx-clear       clear all tx error injections
+	#   <op> clear     clear all rx and tx error injections for <op>
+	#   <op> rx-clear  clear all rx error injections for <op>
+	#   <op> tx-clear  clear all tx error injections for <op>
+	#
+	# RX error injection:
+	#   <op>[,<mode>] rx-nack              NACK the message instead of sending an ACK
+	#   <op>[,<mode>] rx-low-drive <bit>   force a low-drive condition at this bit position
+	#   <op>[,<mode>] rx-add-byte          add a spurious byte to the received CEC message
+	#   <op>[,<mode>] rx-remove-byte       remove the last byte from the received CEC message
+	#   <op>[,<mode>] rx-arb-lost <poll>   generate a POLL message to trigger an arbitration lost
+	#

+	#   tx-custom-high-usecs <usecs>       define the 'high' time for the custom pulse
+	#   tx-custom-pulse                    transmit the custom pulse once the bus is idle
+	#
+	# TX error injection:
+	#   <op>[,<mode>] tx-no-eom            don't set the EOM bit
+	#   <op>[,<mode>] tx-early-eom         set the EOM bit one byte too soon
+	#   <op>[,<mode>] tx-add-bytes <num>   append <num> (1-255) spurious bytes to the message
+	#   <op>[,<mode>] tx-remove-byte       drop the last byte from the message
+	#   <op>[,<mode>] tx-short-bit <bit>   make this bit shorter than allowed

+	#   <op>[,<mode>] tx-long-start        send a start pulse that's too long
+	#   <op>[,<mode>] tx-custom-start      send the custom pulse instead of the start pulse
+	#   <op>[,<mode>] tx-last-bit <bit>    stop sending after this bit
+	#   <op>[,<mode>] tx-low-drive <bit>   force a low-drive condition at this bit position
+	#

+	# <bit>      CEC message bit (0-159)
+	#            10 bits per 'byte': bits 0-7: data, bit 8: EOM, bit 9: ACK
+	# <poll>     CEC poll message used to test arbitration lost (0x00-0xff, default 0x0f)
+	# <usecs>    microseconds (0-10000000, default 1000)
+
+	clear
+
+You can write error injection commands to ``error-inj`` using
+``echo 'cmd' >error-inj`` or ``cat cmd.txt >error-inj``. The ``cat error-inj``
+output contains the current error commands. You can save the output to a file
+and use it as an input to ``error-inj`` later.
+
+Basic Syntax
+------------
+
+Leading spaces/tabs are ignored. If the next character is a ``#`` or the end
+of the line was reached, then the whole line is ignored. Otherwise a command
+is expected.
+
+The error injection commands fall in two main groups: those relating to
+receiving CEC messages and those relating to transmitting CEC messages. In
+addition, there are commands to clear existing error injection commands and
+to create custom pulses on the CEC bus.
+
+Most error injection commands can be executed for specific CEC opcodes or for
+all opcodes (``any``). Each command also has a 'mode' which can be ``off``
+(can be used to turn off an existing error injection command), ``once``
+(the default) which will trigger the error injection only once for the next
+received or transmitted message, ``always`` to always trigger the error
+injection and ``toggle`` to toggle the error injection on or off for every
+transmit or receive.
+
+So '``any rx-nack``' will NACK the next received CEC message,
+'``any,always rx-nack``' will NACK all received CEC messages and
+'``0x82,toggle rx-nack``' will only NACK if an Active Source message was
+received and do that only for every other received message.
+
+After an error was injected with mode ``once`` the error injection command
+is cleared automatically, so ``once`` is a one-time deal.
+
+All combinations of ``<op>`` and error injection commands can co-exist. So
+this is fine::
+
+	0x9e tx-add-bytes 1
+	0x9e tx-early-eom
+	0x9f tx-add-bytes 2
+	any rx-nack
+
+All four error injection commands will be active simultaneously.
+
+However, if the same ``<op>`` and command combination is specified,
+but with different arguments::
+
+	0x9e tx-add-bytes 1
+	0x9e tx-add-bytes 2
+
+Then the second will overwrite the first.
+
+Clear Error Injections
+----------------------
+
+``clear``
+    Clear all error injections.
+
+``rx-clear``
+    Clear all receive error injections
+
+``tx-clear``
+    Clear all transmit error injections
+
+``<op> clear``
+    Clear all error injections for the given opcode.
+
+``<op> rx-clear``
+    Clear all receive error injections for the given opcode.
+
+``<op> tx-clear``
+    Clear all transmit error injections for the given opcode.
+
+Receive Messages
+----------------
+
+``<op>[,<mode>] rx-nack``
+    NACK broadcast messages and messages directed to this CEC adapter.
+    Every byte of the message will be NACKed in case the transmitter
+    keeps transmitting after the first byte was NACKed.
+
+``<op>[,<mode>] rx-low-drive <bit>``
+    Force a Low Drive condition at this bit position. If <op> specifies
+    a specific CEC opcode then the bit position must be at least 18,
+    otherwise the opcode hasn't been received yet. This tests if the
+    transmitter can handle the Low Drive condition correctly and reports
+    the error correctly. Note that a Low Drive in the first 4 bits can also
+    be interpreted as an Arbitration Lost condition by the transmitter.
+    This is implementation dependent.
+
+``<op>[,<mode>] rx-add-byte``
+    Add a spurious 0x55 byte to the received CEC message, provided
+    the message was 15 bytes long or less. This is useful to test
+    the high-level protocol since spurious bytes should be ignored.
+
+``<op>[,<mode>] rx-remove-byte``
+    Remove the last byte from the received CEC message, provided it
+    was at least 2 bytes long. This is useful to test the high-level
+    protocol since messages that are too short should be ignored.
+
+``<op>[,<mode>] rx-arb-lost <poll>``
+    Generate a POLL message to trigger an Arbitration Lost condition.
+    This command is only allowed for ``<op>`` values of ``next`` or ``all``.
+    As soon as a start bit has been received the CEC adapter will switch
+    to transmit mode and it will transmit a POLL message. By default this is
+    0x0f, but it can also be specified explicitly via the ``<poll>`` argument.
+
+    This command can be used to test the Arbitration Lost condition in
+    the remote CEC transmitter. Arbitration happens when two CEC adapters
+    start sending a message at the same time. In that case the initiator
+    with the most leading zeroes wins and the other transmitter has to
+    stop transmitting ('Arbitration Lost'). This is very hard to test,
+    except by using this error injection command.
+
+    This does not work if the remote CEC transmitter has logical address
+    0 ('TV') since that will always win.
+
+Transmit Messages
+-----------------
+
+``tx-ignore-nack-until-eom``
+    This setting changes the behavior of transmitting CEC messages. Normally
+    as soon as the receiver NACKs a byte the transmit will stop, but the
+    specification also allows that the full message is transmitted and only
+    at the end will the transmitter look at the ACK bit. This is not
+    recommended behavior since there is no point in keeping the CEC bus busy
+    for longer than is strictly needed. Especially given how slow the bus is.
+
+    This setting can be used to test how well a receiver deals with
+    transmitters that ignore NACKs until the very end of the message.
+
+``<op>[,<mode>] tx-no-eom``
+    Don't set the EOM bit. Normally the last byte of the message has the EOM
+    (End-Of-Message) bit set. With this command the transmit will just stop
+    without ever sending an EOM. This can be used to test how a receiver
+    handles this case. Normally receivers have a time-out after which
+    they will go back to the Idle state.
+
+``<op>[,<mode>] tx-early-eom``
+    Set the EOM bit one byte too soon. This obviously only works for messages
+    of two bytes or more. The EOM bit will be set for the second-to-last byte
+    and not for the final byte. The receiver should ignore the last byte in
+    this case. Since the resulting message is likely to be too short for this
+    same reason the whole message is typically ignored. The receiver should be
+    in Idle state after the last byte was transmitted.
+
+``<op>[,<mode>] tx-add-bytes <num>``
+    Append ``<num>`` (1-255) spurious bytes to the message. The extra bytes
+    have the value of the byte position in the message. So if you transmit a
+    two byte message (e.g. a Get CEC Version message) and add 2 bytes, then
+    the full message received by the remote CEC adapter is
+    ``0x40 0x9f 0x02 0x03``.
+
+    This command can be used to test buffer overflows in the receiver. E.g.
+    what does it do when it receives more than the maximum message size of 16
+    bytes.
+
+``<op>[,<mode>] tx-remove-byte``
+    Drop the last byte from the message, provided the message is at least
+    two bytes long. The receiver should ignore messages that are too short.
+
+``<op>[,<mode>] tx-short-bit <bit>``
+    Make this bit period shorter than allowed. The bit position cannot be
+    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
+    must be at least 18, otherwise the opcode hasn't been received yet.
+    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
+    With this command the period of this bit is 1.8 milliseconds, this is
+    done by reducing the time the CEC bus is high. This bit period is less
+    than is allowed and the receiver should respond with a Low Drive
+    condition.
+
+    This command is ignored for 0 bits in bit positions 0 to 3. This is
+    because the receiver also looks for an Arbitration Lost condition in
+    those first four bits and it is undefined what will happen if it
+    sees a too-short 0 bit.
+
+``<op>[,<mode>] tx-long-bit <bit>``
+    Make this bit period longer than is valid. The bit position cannot be
+    an Ack bit.  If <op> specifies a specific CEC opcode then the bit position
+    must be at least 18, otherwise the opcode hasn't been received yet.
+    Normally the period of a data bit is between 2.05 and 2.75 milliseconds.
+    With this command the period of this bit is 2.9 milliseconds, this is
+    done by increasing the time the CEC bus is high.
+
+    Even though this bit period is longer than is valid it is undefined what
+    a receiver will do. It might just accept it, or it might time out and
+    return to Idle state. Unfortunately the CEC specification is silent about
+    this.
+
+    This command is ignored for 0 bits in bit positions 0 to 3. This is
+    because the receiver also looks for an Arbitration Lost condition in
+    those first four bits and it is undefined what will happen if it
+    sees a too-long 0 bit.
+
+``<op>[,<mode>] tx-short-start``
+    Make this start bit period shorter than allowed. Normally the period of
+    a start bit is between 4.3 and 4.7 milliseconds. With this command the
+    period of the start bit is 4.1 milliseconds, this is done by reducing
+    the time the CEC bus is high. This start bit period is less than is
+    allowed and the receiver should return to Idle state when this is detected.
+
+``<op>[,<mode>] tx-long-start``
+    Make this start bit period longer than is valid. Normally the period of
+    a start bit is between 4.3 and 4.7 milliseconds. With this command the
+    period of the start bit is 5 milliseconds, this is done by increasing
+    the time the CEC bus is high. This start bit period is more than is
+    valid and the receiver should return to Idle state when this is detected.
+
+    Even though this start bit period is longer than is valid it is undefined
+    what a receiver will do. It might just accept it, or it might time out and
+    return to Idle state. Unfortunately the CEC specification is silent about
+    this.
+
+``<op>[,<mode>] tx-last-bit <bit>``
+    Just stop transmitting after this bit.  If <op> specifies a specific CEC
+    opcode then the bit position must be at least 18, otherwise the opcode
+    hasn't been received yet. This command can be used to test how the receiver
+    reacts when a message just suddenly stops. It should time out and go back
+    to Idle state.
+
+``<op>[,<mode>] tx-low-drive <bit>``
+    Force a Low Drive condition at this bit position. If <op> specifies a
+    specific CEC opcode then the bit position must be at least 18, otherwise
+    the opcode hasn't been received yet. This can be used to test how the
+    receiver handles Low Drive conditions. Note that if this happens at bit
+    positions 0-3 the receiver can interpret this as an Arbitration Lost
+    condition. This is implementation dependent.
+
+Custom Pulses
+-------------
+
+``tx-custom-low-usecs <usecs>``
+    This defines the duration in microseconds that the custom pulse pulls
+    the CEC line low. The default is 1000 microseconds.
+
+``tx-custom-high-usecs <usecs>``
+    This defines the duration in microseconds that the custom pulse keeps the
+    CEC line high (unless another CEC adapter pulls it low in that time).
+    The default is 1000 microseconds. The total period of the custom pulse is
+    ``tx-custom-low-usecs + tx-custom-high-usecs``.
+
+``<op>[,<mode>] tx-custom-bit <bit>``
+    Send the custom bit instead of a regular data bit. The bit position cannot
+    be an Ack bit.  If <op> specifies a specific CEC opcode then the bit
+    position must be at least 18, otherwise the opcode hasn't been received yet.
+
+``<op>[,<mode>] tx-custom-start``
+    Send the custom bit instead of a regular start bit.
+
+``tx-custom-pulse``
+    Transmit a single custom pulse as soon as the CEC bus is idle.

+succeeded, the device will be ready for use. The significance of
+blocking or non-blocking mode is described in the documentation for
+functions where there is a difference. It does not affect the semantics
+of the open() call itself. A device opened in blocking mode can later be
+put into non-blocking mode (and vice versa) using the F_SETFL command
+of the fcntl system call. This is a standard system call, documented in
+the Linux manual page for fcntl. Only one user can open the Audio Device
+in O_RDWR mode. All other attempts to open the device in this mode will
+fail, and an error code will be returned. If the Audio Device is opened
+in O_RDONLY mode, the only ioctl call that can be used is
+AUDIO_GET_STATUS. All other call will return with an error code.

+Digital TV Audio Device
+#######################
+
+The Digital TV audio device controls the MPEG2 audio decoder of the Digital
+TV hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
+types and and ioctl definitions can be accessed by including
+``linux/dvb/audio.h`` in your application.
+
+Please note that some Digital TV cards don’t have their own MPEG decoder, which
+results in the omission of the audio and video device.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+****************
+Audio Data Types
+****************
+
+This section describes the structures, data types and defines used when
+talking to the audio device.
+
+.. c:type:: audio_stream_source
+
+The audio stream source is set through the AUDIO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demux) or external (user write) source.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_SOURCE_DEMUX,
+	AUDIO_SOURCE_MEMORY
+    } audio_stream_source_t;
+
+AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+AUDIO_SOURCE_MEMORY is selected the stream comes from the application
+through the ``write()`` system call.
+
+
+.. c:type:: audio_play_state
+
+The following values can be returned by the AUDIO_GET_STATUS call
+representing the state of audio playback.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_STOPPED,
+	AUDIO_PLAYING,
+	AUDIO_PAUSED
+    } audio_play_state_t;
+
+
+.. c:type:: audio_channel_select
+
+The audio channel selected via AUDIO_CHANNEL_SELECT is determined by
+the following values.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_STEREO,
+	AUDIO_MONO_LEFT,
+	AUDIO_MONO_RIGHT,
+	AUDIO_MONO,
+	AUDIO_STEREO_SWAPPED
+    } audio_channel_select_t;
+
+
+.. c:type:: audio_status
+
+The AUDIO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+    typedef struct audio_status {
+	boolean AV_sync_state;
+	boolean mute_state;
+	audio_play_state_t play_state;
+	audio_stream_source_t stream_source;
+	audio_channel_select_t channel_select;
+	boolean bypass_mode;
+	audio_mixer_t mixer_state;
+    } audio_status_t;
+
+
+.. c:type:: audio_mixer
+
+The following structure is used by the AUDIO_SET_MIXER call to set the
+audio volume.
+
+
+.. code-block:: c
+
+    typedef struct audio_mixer {
+	unsigned int volume_left;
+	unsigned int volume_right;
+    } audio_mixer_t;
+
+
+.. _audio_encodings:
+
+audio encodings
+===============
+
+A call to AUDIO_GET_CAPABILITIES returns an unsigned integer with the
+following bits set according to the hardwares capabilities.
+
+
+.. code-block:: c

+
+    -  - ``O_RDWR``
+       - read/write access
+
+    -  - ``O_NONBLOCK``
+       - open in non-blocking mode
+         (blocking mode is the default)
+
+
+Description
+-----------
+
+This system call opens a named ca device (e.g. ``/dev/dvb/adapter?/ca?``)
+for subsequent use.
+
+When an ``open()`` call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the ``open()`` call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the ``F_SETFL`` command of the ``fcntl`` system call. This is a
+standard system call, documented in the Linux manual page for fcntl.
+Only one user can open the CA Device in ``O_RDWR`` mode. All other
+attempts to open the device in this mode will fail, and an error code
+will be returned.
+
+
+Return Value
+------------
+
+
+On success 0 is returned.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.
+
+Generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+DMX_EXPBUF - Export a buffer as a DMABUF file descriptor.
+
+.. warning:: this API is still experimental
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, DMX_EXPBUF, struct dmx_exportbuffer *argp )
+    :name: DMX_EXPBUF
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``argp``
+    Pointer to struct :c:type:`dmx_exportbuffer`.
+
+
+Description
+===========
+
+This ioctl is an extension to the memory mapping I/O method.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the :ref:`DMX_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct :c:type:`dmx_exportbuffer`.
+Applications must set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with :ref:`DMX_REQBUFS`
+(struct :c:type:`dmx_requestbuffers` ``count``) minus one.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported.
+All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`DMX_EXPBUF` calls.
+
+After calling :ref:`DMX_EXPBUF` the ``fd`` field will be set by a
+driver, on success. This is a DMABUF file descriptor. The application may
+pass it to other DMABUF-aware devices. It is recommended to close a DMABUF
+file when it is no longer used to allow the associated memory to be reclaimed.
+
+
+Examples
+========
+
+
+.. code-block:: c
+
+    int buffer_export(int v4lfd, enum dmx_buf_type bt, int index, int *dmafd)
+    {
+	struct dmx_exportbuffer expbuf;
+
+	memset(&expbuf, 0, sizeof(expbuf));
+	expbuf.type = bt;
+	expbuf.index = index;
+	if (ioctl(v4lfd, DMX_EXPBUF, &expbuf) == -1) {
+	    perror("DMX_EXPBUF");
+	    return -1;
+	}
+
+	*dmafd = expbuf.fd;
+
+	return 0;
+    }
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    A queue is not in MMAP mode or DMABUF exporting is not supported or
+    ``flags`` or ``index`` fields are invalid.

+
+
+Description
+-----------
+
+This system call, used with a device name of ``/dev/dvb/adapter?/demux?``,
+allocates a new filter and returns a handle which can be used for
+subsequent control of that filter. This call has to be made for each
+filter to be used, i.e. every returned file descriptor is a reference to
+a single filter. ``/dev/dvb/adapter?/dvr?`` is a logical device to be used
+for retrieving Transport Streams for digital video recording. When
+reading from this device a transport stream containing the packets from
+all PES filters set in the corresponding demux device
+(``/dev/dvb/adapter?/demux?``) having the output set to ``DMX_OUT_TS_TAP``.
+A recorded Transport Stream is replayed by writing to this device.
+
+The significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the ``open()`` call itself. A device opened
+in blocking mode can later be put into non-blocking mode (and vice versa)
+using the ``F_SETFL`` command of the fcntl system call.
+
+
+Return Value
+------------
+
+On success 0 is returned.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.

+dmx-mmap - Map device memory into application address space
+
+.. warning:: this API is still experimental
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+    #include <sys/mman.h>
+
+
+.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+    :name: dmx-mmap
+
+Arguments
+=========
+
+``start``
+    Map the buffer to this address in the application's address space.
+    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+    multiple of the pagesize and mmap will fail when the specified
+    address cannot be used. Use of this option is discouraged;
+    applications should just specify a ``NULL`` pointer here.
+
+``length``
+    Length of the memory area to map. This must be a multiple of the
+    DVB packet length (188, on most drivers).
+
+``prot``
+    The ``prot`` argument describes the desired memory protection.
+    Regardless of the device type and the direction of data exchange it
+    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+    and write access to image buffers. Drivers should support at least
+    this combination of flags.
+
+``flags``
+    The ``flags`` parameter specifies the type of the mapped object,
+    mapping options and whether modifications made to the mapped copy of
+    the page are private to the process or are to be shared with other
+    references.
+
+    ``MAP_FIXED`` requests that the driver selects no other address than
+    the one specified. If the specified address cannot be used,
+    :ref:`mmap() <dmx-mmap>` will fail. If ``MAP_FIXED`` is specified,
+    ``start`` must be a multiple of the pagesize. Use of this option is
+    discouraged.
+
+    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+    ``MAP_SHARED`` allows applications to share the mapped memory with
+    other (e. g. child-) processes.
+
+    .. note::
+
+       The Linux Digital TV applications should not set the
+       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+       flags.
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``offset``
+    Offset of the buffer in device memory, as returned by
+    :ref:`DMX_QUERYBUF` ioctl.
+
+
+Description
+===========
+
+The :ref:`mmap() <dmx-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`DMX_QUERYBUF` ioctl. Buffers must be allocated with the
+:ref:`DMX_REQBUFS` ioctl before they can be queried.
+
+To unmap buffers the :ref:`munmap() <dmx-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <dmx-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+    ``fd`` is not a valid file descriptor.
+
+EACCES
+    ``fd`` is not open for reading and writing.
+
+EINVAL
+    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
+    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
+
+    The ``flags`` or ``prot`` value is not supported.
+
+    No buffers have been allocated with the
+    :ref:`DMX_REQBUFS` ioctl.
+
+ENOMEM
+    Not enough physical or virtual memory was available to complete the
+    request.

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``argp``
+    Pointer to struct :c:type:`dmx_buffer`.
+
+
+Description
+===========
+
+Applications call the ``DMX_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``index`` field. Valid index
+numbers range from zero to the number of buffers allocated with
+:ref:`DMX_REQBUFS` (struct :c:type:`dmx_requestbuffers` ``count``) minus
+one. The contents of the struct :c:type:`dmx_buffer` returned
+by a :ref:`DMX_QUERYBUF` ioctl will do as well.
+
+When ``DMX_QBUF`` is called with a pointer to this structure, it locks the
+memory pages of the buffer in physical memory, so they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+the device is closed.
+
+Applications call the ``DMX_DQBUF`` ioctl to dequeue a filled
+(capturing) buffer from the driver's outgoing queue.
+They just set the ``index`` field with the buffer ID to be queued.
+When ``DMX_DQBUF`` is called with a pointer to struct :c:type:`dmx_buffer`,
+the driver fills the remaining fields or returns an error code.
+
+By default ``DMX_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <dmx_fopen>` function, ``DMX_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The struct :c:type:`dmx_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EAGAIN
+    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
+    buffer was in the outgoing queue.
+
+EINVAL
+    The ``index`` is out of bounds, or no buffers have been allocated yet.
+
+EIO
+    ``DMX_DQBUF`` failed due to an internal error. Can also indicate
+    temporary problems like signal loss or CRC errors.

+Arguments
+=========

+    File descriptor returned by :ref:`open() <dmx_fopen>`.
+
+``argp``
+    Pointer to struct :c:type:`dmx_requestbuffers`.
+
+Description
+===========
+
+This ioctl is used to initiate a memory mapped or DMABUF based demux I/O.
+
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+struct :c:type:`dmx_requestbuffers` structure. They set the  ``count`` field
+to the desired number of buffers,  and ``size`` to the size of each
+buffer.
+
+When the ioctl is called with a pointer to this structure, the driver will
+attempt to allocate the requested number of buffers and it stores the actual
+number allocated in the ``count`` field. The ``count`` can be smaller than the number requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. The actual allocated buffer size can is returned
+at ``size``, and can be smaller than what's requested.
+
+When this I/O method is not supported, the ioctl returns an ``EOPNOTSUPP``
+error code.
+
+Applications can call :ref:`DMX_REQBUFS` again to change the number of
+buffers, however this cannot succeed when any buffers are still mapped.
+A ``count`` value of zero frees all buffers, after aborting or finishing
+any DMA in progress.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EOPNOTSUPP
+    The  the requested I/O method is not supported.

+
+Description
+-----------
+
+This ioctl call sets up a filter according to the filter and mask
+parameters provided. A timeout may be defined stating number of seconds
+to wait for a section to be loaded. A value of 0 means that no timeout
+should be applied. Finally there is a flag field where it is possible to
+state whether a section should be CRC-checked, whether the filter should
+be a ”one-shot” filter, i.e. if the filtering operation should be
+stopped after the first section is received, and whether the filtering
+operation should be started immediately (without waiting for a
+:ref:`DMX_START` ioctl call). If a filter was previously set-up, this
+filter will be canceled, and the receive buffer will be flushed.

+
+*******************
+frontend parameters
+*******************
+
+The kind of parameters passed to the frontend device for tuning depend
+on the kind of hardware you are using.
+
+The struct ``dvb_frontend_parameters`` uses a union with specific
+per-system parameters. However, as newer delivery systems required more
+data, the structure size weren't enough to fit, and just extending its
+size would break the existing applications. So, those parameters were
+replaced by the usage of
+:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
+ioctl's. The new API is flexible enough to add new parameters to
+existing delivery systems, and to add newer delivery systems.
+
+So, newer applications should use
+:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
+instead, in order to be able to support the newer System Delivery like
+DVB-S2, DVB-T2, DVB-C2, ISDB, etc.
+
+All kinds of parameters are combined as a union in the
+``dvb_frontend_parameters`` structure:
+
+
+.. code-block:: c
+
+    struct dvb_frontend_parameters {
+	uint32_t frequency;     /* (absolute) frequency in Hz for QAM/OFDM */
+		    /* intermediate frequency in kHz for QPSK */
+	fe_spectral_inversion_t inversion;
+	union {
+	    struct dvb_qpsk_parameters qpsk;
+	    struct dvb_qam_parameters  qam;
+	    struct dvb_ofdm_parameters ofdm;
+	    struct dvb_vsb_parameters  vsb;
+	} u;
+    };
+
+In the case of QPSK frontends the ``frequency`` field specifies the
+intermediate frequency, i.e. the offset which is effectively added to
+the local oscillator frequency (LOF) of the LNB. The intermediate
+frequency has to be specified in units of kHz. For QAM and OFDM
+frontends the ``frequency`` specifies the absolute frequency and is
+given in Hz.
+
+
+.. c:type:: dvb_qpsk_parameters
+
+QPSK parameters
+===============
+
+For satellite QPSK frontends you have to use the ``dvb_qpsk_parameters``
+structure:
+
+
+.. code-block:: c
+
+     struct dvb_qpsk_parameters {
+	 uint32_t        symbol_rate;  /* symbol rate in Symbols per second */
+	 fe_code_rate_t  fec_inner;    /* forward error correction (see above) */
+     };
+
+
+.. c:type:: dvb_qam_parameters
+
+QAM parameters
+==============
+
+for cable QAM frontend you use the ``dvb_qam_parameters`` structure:
+
+
+.. code-block:: c
+
+     struct dvb_qam_parameters {
+	 uint32_t         symbol_rate; /* symbol rate in Symbols per second */
+	 fe_code_rate_t   fec_inner;   /* forward error correction (see above) */
+	 fe_modulation_t  modulation;  /* modulation type (see above) */
+     };
+
+
+.. c:type:: dvb_vsb_parameters
+
+VSB parameters
+==============
+
+ATSC frontends are supported by the ``dvb_vsb_parameters`` structure:
+
+
+.. code-block:: c
+
+    struct dvb_vsb_parameters {
+	fe_modulation_t modulation; /* modulation type (see above) */
+    };
+
+
+.. c:type:: dvb_ofdm_parameters
+
+OFDM parameters
+===============
+
+DVB-T frontends are supported by the ``dvb_ofdm_parameters`` structure:
+
+
+.. code-block:: c
+
+     struct dvb_ofdm_parameters {
+	 fe_bandwidth_t      bandwidth;
+	 fe_code_rate_t      code_rate_HP;  /* high priority stream code rate */
+	 fe_code_rate_t      code_rate_LP;  /* low priority stream code rate */
+	 fe_modulation_t     constellation; /* modulation type (see above) */
+	 fe_transmit_mode_t  transmission_mode;
+	 fe_guard_interval_t guard_interval;
+	 fe_hierarchy_t      hierarchy_information;
+     };

+
+Tuning into a Digital TV physical channel and starting decoding it
+requires changing a set of parameters, in order to control the tuner,
+the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
+antenna subsystem via Satellite Equipment Control - SEC (on satellite
+systems). The actual parameters are specific to each particular digital
+TV standards, and may change as the digital TV specs evolves.
+
+In the past (up to DVB API version 3 - DVBv3), the strategy used was to have a
+union with the parameters needed to tune for DVB-S, DVB-C, DVB-T and
+ATSC delivery systems grouped there. The problem is that, as the second
+generation standards appeared, the size of such union was not big
+enough to group the structs that would be required for those new
+standards. Also, extending it would break userspace.
+
+So, the legacy union/struct based approach was deprecated, in favor
+of a properties set approach. On such approach,
+:ref:`FE_GET_PROPERTY and FE_SET_PROPERTY <FE_GET_PROPERTY>` are used
+to setup the frontend and read its status.
+
+The actual action is determined by a set of dtv_property cmd/data pairs.
+With one single ioctl, is possible to get/set up to 64 properties.
+
+This section describes the new and recommended way to set the frontend,
+with supports all digital TV delivery systems.
+
+.. note::
+
+   1. On Linux DVB API version 3, setting a frontend was done via
+      struct :c:type:`dvb_frontend_parameters`.
+
+   2. Don't use DVB API version 3 calls on hardware with supports
+      newer standards. Such API provides no support or a very limited
+      support to new standards and/or new hardware.
+
+   3. Nowadays, most frontends support multiple delivery systems.
+      Only with DVB API version 5 calls it is possible to switch between
+      the multiple delivery systems supported by a frontend.
+
+   4. DVB API version 5 is also called *S2API*, as the first
+      new standard added to it was DVB-S2.
+
+**Example**: in order to set the hardware to tune into a DVB-C channel
+at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol rate of 5.217
+Mbauds, those properties should be sent to
+:ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` ioctl:
+
+  :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` = SYS_DVBC_ANNEX_A
+
+  :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` = 651000000
+
+  :ref:`DTV_MODULATION <DTV-MODULATION>` = QAM_256
+
+  :ref:`DTV_INVERSION <DTV-INVERSION>` = INVERSION_AUTO
+
+  :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>` = 5217000
+
+  :ref:`DTV_INNER_FEC <DTV-INNER-FEC>` = FEC_3_4
+
+  :ref:`DTV_TUNE <DTV-TUNE>`
+
+The code that would that would do the above is show in
+:ref:`dtv-prop-example`.

+
+.. attention:: While it is possible to directly call the Kernel code like the

+   `libdvbv5 <https://linuxtv.org/docs/libdvbv5/index.html>`__, as it
+   provides abstraction to work with the supported digital TV standards and
+   provides methods for usual operations like program scanning and to
+   read/write channel descriptor files.

+.. _DTV-FREQUENCY:
+
+DTV_FREQUENCY
+=============
+
+Frequency of the digital TV transponder/channel.
+
+.. note::
+
+  #. For satellite delivery systems, the frequency is in kHz.
+
+  #. For cable and terrestrial delivery systems, the frequency is in
+     Hz.
+
+  #. On most delivery systems, the frequency is the center frequency
+     of the transponder/channel. The exception is for ISDB-T, where
+     the main carrier has a 1/7 offset from the center.
+
+  #. For ISDB-T, the channels are usually transmitted with an offset of
+     about 143kHz. E.g. a valid frequency could be 474,143 kHz. The
+     stepping is  bound to the bandwidth of the channel which is
+     typically 6MHz.
+
+  #. In ISDB-Tsb, the channel consists of only one or three segments the
+     frequency step is 429kHz, 3*429 respectively.
+
+
+.. _DTV-MODULATION:
+
+DTV_MODULATION
+==============
+
+Specifies the frontend modulation type for delivery systems that
+supports more multiple modulations.
+
+The modulation can be one of the types defined by enum :c:type:`fe_modulation`.
+
+Most of the digital TV standards offers more than one possible
+modulation type.
+
+The table below presents a summary of the types of modulation types
+supported by each delivery system, as currently defined by specs.
+
+======================= =======================================================
+Standard		Modulation types
+======================= =======================================================
+ATSC (version 1)	8-VSB and 16-VSB.
+DMTB			4-QAM, 16-QAM, 32-QAM, 64-QAM and 4-QAM-NR.
+DVB-C Annex A/C		16-QAM, 32-QAM, 64-QAM and 256-QAM.
+DVB-C Annex B		64-QAM.
+DVB-T			QPSK, 16-QAM and 64-QAM.
+DVB-T2			QPSK, 16-QAM, 64-QAM and 256-QAM.
+DVB-S			No need to set. It supports only QPSK.
+DVB-S2			QPSK, 8-PSK, 16-APSK and 32-APSK.
+ISDB-T			QPSK, DQPSK, 16-QAM and 64-QAM.
+ISDB-S			8-PSK, QPSK and BPSK.
+======================= =======================================================
+
+.. note::
+
+   Please notice that some of the above modulation types may not be
+   defined currently at the Kernel. The reason is simple: no driver
+   needed such definition yet.
+
+
+.. _DTV-BANDWIDTH-HZ:
+
+DTV_BANDWIDTH_HZ
+================
+
+Bandwidth for the channel, in HZ.
+
+Should be set only for terrestrial delivery systems.
+
+Possible values: ``1712000``, ``5000000``, ``6000000``, ``7000000``,
+``8000000``, ``10000000``.
+
+======================= =======================================================
+Terrestrial Standard	Possible values for bandwidth
+======================= =======================================================
+ATSC (version 1)	No need to set. It is always 6MHz.
+DMTB			No need to set. It is always 8MHz.
+DVB-T			6MHz, 7MHz and 8MHz.
+DVB-T2			1.172 MHz, 5MHz, 6MHz, 7MHz, 8MHz and 10MHz
+ISDB-T			5MHz, 6MHz, 7MHz and 8MHz, although most places
+			use 6MHz.
+======================= =======================================================
+
+
+.. note::
+
+
+  #. For ISDB-Tsb, the bandwidth can vary depending on the number of
+     connected segments.
+
+     It can be easily derived from other parameters
+     (DTV_ISDBT_SB_SEGMENT_IDX, DTV_ISDBT_SB_SEGMENT_COUNT).
+
+  #. On Satellite and Cable delivery systems, the bandwidth depends on
+     the symbol rate. So, the Kernel will silently ignore any setting
+     :ref:`DTV-BANDWIDTH-HZ`. I will however fill it back with a
+     bandwidth estimation.
+
+     Such bandwidth estimation takes into account the symbol rate set with
+     :ref:`DTV-SYMBOL-RATE`, and the rolloff factor, with is fixed for
+     DVB-C and DVB-S.
+
+     For DVB-S2, the rolloff should also be set via :ref:`DTV-ROLLOFF`.

+
+DTV_ISDBT_PARTIAL_RECEPTION
+===========================
+
+Used only on ISDB.
+
+If ``DTV_ISDBT_SOUND_BROADCASTING`` is '0' this bit-field represents

+
+If '1' ``DTV_ISDBT_LAYERA_*`` values are assigned to the center segment
+and ``DTV_ISDBT_LAYERA_SEGMENT_COUNT`` has to be '1'.
+

+============================
+
+Used only on ISDB.
+
+This field represents whether the other DTV_ISDBT_*-parameters are
+referring to an ISDB-T and an ISDB-Tsb channel. (See also
+``DTV_ISDBT_PARTIAL_RECEPTION``).
+
+Possible values: 0, 1, -1 (AUTO)
+
+
+.. _DTV-ISDBT-SB-SUBCHANNEL-ID:
+
+DTV_ISDBT_SB_SUBCHANNEL_ID
+==========================
+
+Used only on ISDB.
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+(Note of the author: This might not be the correct description of the
+``SUBCHANNEL-ID`` in all details, but it is my understanding of the
+technical background needed to program a device)
+
+An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a
+set of connected ISDB-Tsb channels. In this set of channels every
+channel can be received independently. The number of connected ISDB-Tsb
+segment can vary, e.g. depending on the frequency spectrum bandwidth
+available.
+
+Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
+broadcaster has several possibilities to put those channels in the air:
+Assuming a normal 13-segment ISDB-T spectrum he can align the 8 segments
+from position 1-8 to 5-13 or anything in between.
+
+The underlying layer of segments are subchannels: each segment is
+consisting of several subchannels with a predefined IDs. A sub-channel
+is used to help the demodulator to synchronize on the channel.
+
+An ISDB-T channel is always centered over all sub-channels. As for the
+example above, in ISDB-Tsb it is no longer as simple as that.
+
+``The DTV_ISDBT_SB_SUBCHANNEL_ID`` parameter is used to give the
+sub-channel ID of the segment to be demodulated.
+
+Possible values: 0 .. 41, -1 (AUTO)
+
+
+.. _DTV-ISDBT-SB-SEGMENT-IDX:
+
+DTV_ISDBT_SB_SEGMENT_IDX
+========================
+
+Used only on ISDB.
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+``DTV_ISDBT_SB_SEGMENT_IDX`` gives the index of the segment to be
+demodulated for an ISDB-Tsb channel where several of them are
+transmitted in the connected manner.
+
+Possible values: 0 .. ``DTV_ISDBT_SB_SEGMENT_COUNT`` - 1
+
+Note: This value cannot be determined by an automatic channel search.
+
+
+.. _DTV-ISDBT-SB-SEGMENT-COUNT:
+
+DTV_ISDBT_SB_SEGMENT_COUNT
+==========================
+
+Used only on ISDB.
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+``DTV_ISDBT_SB_SEGMENT_COUNT`` gives the total count of connected
+ISDB-Tsb channels.
+
+Possible values: 1 .. 13
+
+Note: This value cannot be determined by an automatic channel search.
+
+
+.. _isdb-hierq-layers:
+
+DTV-ISDBT-LAYER[A-C] parameters
+===============================
+
+Used only on ISDB.
+
+ISDB-T channels can be coded hierarchically. As opposed to DVB-T in
+ISDB-T hierarchical layers can be decoded simultaneously. For that
+reason a ISDB-T demodulator has 3 Viterbi and 3 Reed-Solomon decoders.
+
+ISDB-T has 3 hierarchical layers which each can use a part of the
+available segments. The total number of segments over all layers has to
+13 in ISDB-T.
+
+There are 3 parameter sets, for Layers A, B and C.
+
+
+.. _DTV-ISDBT-LAYER-ENABLED:
+
+DTV_ISDBT_LAYER_ENABLED
+-----------------------
+
+Used only on ISDB.
+
+Hierarchical reception in ISDB-T is achieved by enabling or disabling
+layers in the decoding process. Setting all bits of
+``DTV_ISDBT_LAYER_ENABLED`` to '1' forces all layers (if applicable) to
+be demodulated. This is the default.
+
+If the channel is in the partial reception mode
+(``DTV_ISDBT_PARTIAL_RECEPTION`` = 1) the central segment can be decoded
+independently of the other 12 segments. In that mode layer A has to have
+a ``SEGMENT_COUNT`` of 1.
+
+In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb according
+to ``DTV_ISDBT_PARTIAL_RECEPTION``. ``SEGMENT_COUNT`` must be filled
+accordingly.
+
+Only the values of the first 3 bits are used. Other bits will be silently ignored:
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 0: layer A enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 1: layer B enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 2: layer C enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bits 3-31: unused
+
+
+.. _DTV-ISDBT-LAYER-FEC:

+
+Possible values are: ``FEC_AUTO``, ``FEC_1_2``, ``FEC_2_3``, ``FEC_3_4``,
+``FEC_5_6``, ``FEC_7_8``
+

+:c:type:`fe_modulation`.
+
+Possible values are: ``QAM_AUTO``, ``QPSK``, ``QAM_16``, ``QAM_64``, ``DQPSK``
+
+.. note::
+
+   #. If layer C is ``DQPSK``, then layer B has to be ``DQPSK``.
+
+   #. If layer B is ``DQPSK`` and ``DTV_ISDBT_PARTIAL_RECEPTION``\ = 0,
+      then layer has to be ``DQPSK``.

+
+.. note::
+
+   #. ISDB-T supports three carrier/symbol-size: 8K, 4K, 2K. It is called
+      **mode** on such standard, and are numbered from 1 to 3:
+
+      ====	========	========================
+      Mode	FFT size	Transmission mode
+      ====	========	========================
+      1		2K		``TRANSMISSION_MODE_2K``
+      2		4K		``TRANSMISSION_MODE_4K``
+      3		8K		``TRANSMISSION_MODE_8K``
+      ====	========	========================
+
+   #. If ``DTV_TRANSMISSION_MODE`` is set the ``TRANSMISSION_MODE_AUTO``
+      the hardware will try to find the correct FFT-size (if capable) and
+      will use TMCC to fill in the missing parameters.
+
+   #. DVB-T specifies 2K and 8K as valid sizes.
+
+   #. DVB-T2 specifies 1K, 2K, 4K, 8K, 16K and 32K.
+
+   #. DTMB specifies C1 and C3780.
+
+
+.. _DTV-HIERARCHY:
+
+DTV_HIERARCHY
+=============
+
+Used only on DVB-T and DVB-T2.
+
+Frontend hierarchy.
+
+The acceptable values are defined by :c:type:`fe_hierarchy`.
+
+
+.. _DTV-STREAM-ID:
+
+DTV_STREAM_ID
+=============
+
+Used on DVB-S2, DVB-T2 and ISDB-S.
+
+DVB-S2, DVB-T2 and ISDB-S support the transmission of several streams on
+a single transport stream. This property enables the digital TV driver to
+handle substream filtering, when supported by the hardware. By default,
+substream filtering is disabled.
+
+For DVB-S2 and DVB-T2, the valid substream id range is from 0 to 255.
+
+For ISDB, the valid substream id range is from 1 to 65535.
+
+To disable it, you should use the special macro NO_STREAM_ID_FILTER.
+
+Note: any value outside the id range also disables filtering.
+
+
+.. _DTV-DVBT2-PLP-ID-LEGACY:
+
+DTV_DVBT2_PLP_ID_LEGACY
+=======================
+
+Obsolete, replaced with DTV_STREAM_ID.
+
+
+.. _DTV-ENUM-DELSYS:
+
+DTV_ENUM_DELSYS
+===============
+
+A Multi standard frontend needs to advertise the delivery systems
+provided. Applications need to enumerate the provided delivery systems,
+before using any other operation with the frontend. Prior to it's
+introduction, FE_GET_INFO was used to determine a frontend type. A
+frontend which provides more than a single delivery system,
+FE_GET_INFO doesn't help much. Applications which intends to use a
+multistandard frontend must enumerate the delivery systems associated
+with it, rather than trying to use FE_GET_INFO. In the case of a
+legacy frontend, the result is just the same as with FE_GET_INFO, but
+in a more structured format
+
+The acceptable values are defined by :c:type:`fe_delivery_system`.
+
+
+.. _DTV-INTERLEAVING:
+
+DTV_INTERLEAVING
+================
+
+Time interleaving to be used.
+
+The acceptable values are defined by :c:type:`fe_interleaving`.
+
+
+.. _DTV-LNA:
+
+DTV_LNA
+=======
+
+Low-noise amplifier.
+
+Hardware might offer controllable LNA which can be set manually using
+that parameter. Usually LNA could be found only from terrestrial devices
+if at all.
+
+Possible values: 0, 1, LNA_AUTO
+
+0, LNA off
+
+1, LNA on
+
+use the special macro LNA_AUTO to set LNA auto
+
+
+.. _DTV-SCRAMBLING-SEQUENCE-INDEX:
+
+DTV_SCRAMBLING_SEQUENCE_INDEX
+=============================
+
+Used on DVB-S2.
+
+This 18 bit field, when present, carries the index of the DVB-S2 physical
+layer scrambling sequence as defined in clause 5.5.4 of EN 302 307.
+There is no explicit signalling method to convey scrambling sequence index
+to the receiver. If S2 satellite delivery system descriptor is available
+it can be used to read the scrambling sequence index (EN 300 468 table 41).
+
+By default, gold scrambling sequence index 0 is used.
+
+The valid scrambling sequence index range is from 0 to 262142.

+ISDB-T delivery system
+======================
+
+This ISDB-T/ISDB-Tsb API extension should reflect all information needed
+to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
+very sophisticated devices won't need certain parameters to tune.
+
+The information given here should help application writers to know how
+to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API.
+
+The details given here about ISDB-T and ISDB-Tsb are just enough to
+basically show the dependencies between the needed parameter values, but
+surely some information is left out. For more detailed information see
+the following documents:
+
+ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
+Broadcasting" and
+
+ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
+Broadcasting".
+
+In order to understand the ISDB specific parameters, one has to have
+some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
+to be known to the reader that an ISDB-T channel consists of 13
+segments, that it can have up to 3 layer sharing those segments, and
+things like that.

+The values are returned via ``dtv_property.stat``. If the property is
+supported, ``dtv_property.stat.len`` is bigger than zero.
+
+For most delivery systems, ``dtv_property.stat.len`` will be 1 if the
+stats is supported, and the properties will return a single value for
+each parameter.
+
+It should be noted, however, that new OFDM delivery systems like ISDB
+can use different modulation types for each group of carriers. On such
+standards, up to 3 groups of statistics can be provided, and
+``dtv_property.stat.len`` is updated to reflect the "global" metrics,
+plus one metric per each carrier group (called "layer" on ISDB).
+
+So, in order to be consistent with other delivery systems, the first
+value at :c:type:`dtv_property.stat.dtv_stats <dtv_stats>` array refers
+to the global metric. The other elements of the array represent each
+layer, starting from layer A(index 1), layer B (index 2) and so on.
+
+The number of filled elements are stored at ``dtv_property.stat.len``.
+
+Each element of the ``dtv_property.stat.dtv_stats`` array consists on
+two elements:
+
+-  ``svalue`` or ``uvalue``, where ``svalue`` is for signed values of
+   the measure (dB measures) and ``uvalue`` is for unsigned values
+   (counters, relative scale)
+
+-  ``scale`` - Scale for the value. It can be:
+
+   -  ``FE_SCALE_NOT_AVAILABLE`` - The parameter is supported by the
+      frontend, but it was not possible to collect it (could be a
+      transitory or permanent condition)
+
+   -  ``FE_SCALE_DECIBEL`` - parameter is a signed value, measured in
+      1/1000 dB
+
+   -  ``FE_SCALE_RELATIVE`` - parameter is a unsigned value, where 0
+      means 0% and 65535 means 100%.
+
+   -  ``FE_SCALE_COUNTER`` - parameter is a unsigned value that counts
+      the occurrence of an event, like bit error, block error, or lapsed
+      time.
+
+
+.. _DTV-STAT-SIGNAL-STRENGTH:
+
+DTV_STAT_SIGNAL_STRENGTH
+========================
+
+Indicates the signal strength level at the analog part of the tuner or
+of the demod.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_DECIBEL`` - signal strength is in 0.001 dBm units, power
+   measured in miliwatts. This value is generally negative.
+
+-  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
+   measurement for power (actually, 0 to 65535).
+
+
+.. _DTV-STAT-CNR:
+
+DTV_STAT_CNR
+============
+
+Indicates the Signal to Noise ratio for the main carrier.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_DECIBEL`` - Signal/Noise ratio is in 0.001 dB units.
+
+-  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
+   measurement for Signal/Noise (actually, 0 to 65535).
+
+
+.. _DTV-STAT-PRE-ERROR-BIT-COUNT:
+
+DTV_STAT_PRE_ERROR_BIT_COUNT
+============================
+
+Measures the number of bit errors before the forward error correction
+(FEC) on the inner coding block (before Viterbi, LDPC or other inner
+code).
+
+This measure is taken during the same interval as
+``DTV_STAT_PRE_TOTAL_BIT_COUNT``.
+
+In order to get the BER (Bit Error Rate) measurement, it should be
+divided by
+:ref:`DTV_STAT_PRE_TOTAL_BIT_COUNT <DTV-STAT-PRE-TOTAL-BIT-COUNT>`.
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_COUNTER`` - Number of error bits counted before the inner
+   coding.
+
+
+.. _DTV-STAT-PRE-TOTAL-BIT-COUNT:
+
+DTV_STAT_PRE_TOTAL_BIT_COUNT
+============================
+
+Measures the amount of bits received before the inner code block, during
+the same period as
+:ref:`DTV_STAT_PRE_ERROR_BIT_COUNT <DTV-STAT-PRE-ERROR-BIT-COUNT>`
+measurement was taken.
+
+It should be noted that this measurement can be smaller than the total
+amount of bits on the transport stream, as the frontend may need to
+manually restart the measurement, losing some data between each
+measurement interval.
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the

+   :ref:`DTV_STAT_PRE_ERROR_BIT_COUNT <DTV-STAT-PRE-ERROR-BIT-COUNT>`.
+
+
+.. _DTV-STAT-POST-ERROR-BIT-COUNT:
+
+DTV_STAT_POST_ERROR_BIT_COUNT
+=============================
+
+Measures the number of bit errors after the forward error correction
+(FEC) done by inner code block (after Viterbi, LDPC or other inner
+code).
+
+This measure is taken during the same interval as
+``DTV_STAT_POST_TOTAL_BIT_COUNT``.
+
+In order to get the BER (Bit Error Rate) measurement, it should be

+
+This measurement is monotonically increased, as the frontend gets more

+Digital TV Frontend API
+#######################
+
+The Digital TV frontend API was designed to support three groups of delivery
+systems: Terrestrial, cable and Satellite. Currently, the following
+delivery systems are supported:
+
+-  Terrestrial systems: DVB-T, DVB-T2, ATSC, ATSC M/H, ISDB-T, DVB-H,
+   DTMB, CMMB
+
+-  Cable systems: DVB-C Annex A/C, ClearQAM (DVB-C Annex B)
+
+-  Satellite systems: DVB-S, DVB-S2, DVB Turbo, ISDB-S, DSS
+
+The Digital TV frontend controls several sub-devices including:
+
+-  Tuner
+
+-  Digital TV demodulator
+
+-  Low noise amplifier (LNA)
+
+-  Satellite Equipment Control (SEC) [#f1]_.
+
+The frontend can be accessed through ``/dev/dvb/adapter?/frontend?``.
+Data types and ioctl definitions can be accessed by including
+``linux/dvb/frontend.h`` in your application.
+
+.. note::
+
+   Transmission via the internet (DVB-IP) and MMT (MPEG Media Transport)
+   is not yet handled by this API but a future extension is possible.
+
+.. [#f1]
+
+   On Satellite systems, the API support for the Satellite Equipment
+   Control (SEC) allows to power control and to send/receive signals to
+   control the antenna subsystem, selecting the polarization and choosing
+   the Intermediate Frequency IF) of the Low Noise Block Converter Feed
+   Horn (LNBf). It supports the DiSEqC and V-SEC protocols. The DiSEqC
+   (digital SEC) specification is available at
+   `Eutelsat <http://www.eutelsat.com/satellites/4_5_5.html>`__.

+    Device to be opened.
+
+``flags``
+    Open flags. Access can either be ``O_RDWR`` or ``O_RDONLY``.
+
+    Multiple opens are allowed with ``O_RDONLY``. In this mode, only

+
+    Only one open is allowed in ``O_RDWR``. In this mode, all ioctls are

+
+    When the ``O_NONBLOCK`` flag is given, the system calls may return
+    ``EAGAIN`` error code when no data is available or when the device
+    driver is temporarily busy.
+
+    Other flags have no effect.
+
+
+Description
+===========
+
+This system call opens a named frontend device
+(``/dev/dvb/adapter?/frontend?``) for subsequent use. Usually the first
+thing to do after a successful open is to find out the frontend type
+with :ref:`FE_GET_INFO`.
+
+The device can be opened in read-only mode, which only allows monitoring
+of device status and statistics, or read/write mode, which allows any
+kind of use (e.g. performing tuning operations.)
+
+In a system with multiple front-ends, it is usually the case that
+multiple devices cannot be open in read/write mode simultaneously. As
+long as a front-end device is opened in read/write mode, other open()
+calls in read/write mode will either fail or block, depending on whether
+non-blocking or blocking mode was specified. A front-end device opened
+in blocking mode can later be put into non-blocking mode (and vice
+versa) using the F_SETFL command of the fcntl system call. This is a
+standard system call, documented in the Linux manual page for fcntl.
+When an open() call has succeeded, the device will be ready for use in
+the specified mode. This implies that the corresponding hardware is
+powered up, and that other front-ends may have been powered down to make
+that possible.
+
+
+Return Value
+============
+
+On success :ref:`open() <frontend_f_open>` returns the new file descriptor.
+On error, -1 is returned, and the ``errno`` variable is set appropriately.
+
+Possible error codes are:
+
+
+On success 0 is returned, and :c:type:`ca_slot_info` is filled.
+
+On error -1 is returned, and the ``errno`` variable is set
+appropriately.

+
+What you need to know
+=====================
+
+The reader of this document is required to have some knowledge in the
+area of digital video broadcasting (Digital TV) and should be familiar with
+part I of the MPEG2 specification ISO/IEC 13818 (aka ITU-T H.222), i.e
+you should know what a program/transport stream (PS/TS) is and what is
+meant by a packetized elementary stream (PES) or an I-frame.
+
+Various Digital TV standards documents are available for download at:
+
+- European standards (DVB): http://www.dvb.org and/or http://www.etsi.org.
+- American standards (ATSC): https://www.atsc.org/standards/
+- Japanese standards (ISDB): http://www.dibeg.org/
+
+It is also necessary to know how to access Linux devices and how to
+use ioctl calls. This also includes the knowledge of C or C++.
+
+
+.. _history:
+
+History
+=======
+
+The first API for Digital TV cards we used at Convergence in late 1999 was an
+extension of the Video4Linux API which was primarily developed for frame
+grabber cards. As such it was not really well suited to be used for Digital
+TV cards and their new features like recording MPEG streams and filtering
+several section and PES data streams at the same time.
+
+In early 2000, Convergence was approached by Nokia with a proposal for a new
+standard Linux Digital TV API. As a commitment to the development of terminals
+based on open standards, Nokia and Convergence made it available to all
+Linux developers and published it on https://linuxtv.org in September
+2000. With the Linux driver for the Siemens/Hauppauge DVB PCI card,
+Convergence provided a first implementation of the Linux Digital TV API.
+Convergence was the maintainer of the Linux Digital TV API in the early
+days.
+
+Now, the API is maintained by the LinuxTV community (i.e. you, the reader
+of this document). The Linux  Digital TV API is constantly reviewed and
+improved together with the improvements at the subsystem's core at the
+Kernel.

+    :align: center
+
+    Components of a Digital TV card/STB
+
+A Digital TV card or set-top-box (STB) usually consists of the
+following main hardware components:
+
+Frontend consisting of tuner and digital TV demodulator
+   Here the raw signal reaches the digital TV hardware from a satellite dish or
+   antenna or directly from cable. The frontend down-converts and
+   demodulates this signal into an MPEG transport stream (TS). In case
+   of a satellite frontend, this includes a facility for satellite
+   equipment control (SEC), which allows control of LNB polarization,
+   multi feed switches or dish rotors.
+
+Conditional Access (CA) hardware like CI adapters and smartcard slots
+   The complete TS is passed through the CA hardware. Programs to which
+   the user has access (controlled by the smart card) are decoded in
+   real time and re-inserted into the TS.
+
+   .. note::
+
+      Not every digital TV hardware provides conditional access hardware.
+
+Demultiplexer which filters the incoming Digital TV MPEG-TS stream
+   The demultiplexer splits the TS into its components like audio and
+   video streams. Besides usually several of such audio and video
+   streams it also contains data streams with information about the
+   programs offered in this or other streams of the same provider.
+
+Audio and video decoder
+   The main targets of the demultiplexer are audio and video
+   decoders. After decoding, they pass on the uncompressed audio and
+   video to the computer screen or to a TV set.
+
+   .. note::
+
+      Modern hardware usually doesn't have a separate decoder hardware, as
+      such functionality can be provided by the main CPU, by the graphics
+      adapter of the system or by a signal processing hardware embedded on
+      a Systems on a Chip (SoC) integrated circuit.
+
+      It may also not be needed for certain usages (e.g. for data-only
+      uses like “internet over satellite”).
+
+:ref:`stb_components` shows a crude schematic of the control and data
+flow between those components.
+
+
+
+.. _dvb_devices:
+
+Linux Digital TV Devices
+========================
+
+The Linux Digital TV API lets you control these hardware components through
+currently six Unix-style character devices for video, audio, frontend,
+demux, CA and IP-over-DVB networking. The video and audio devices
+control the MPEG2 decoder hardware, the frontend device the tuner and
+the Digital TV demodulator. The demux device gives you control over the PES
+and section filters of the hardware. If the hardware does not support
+filtering these filters can be implemented in software. Finally, the CA
+device controls all the conditional access capabilities of the hardware.
+It can depend on the individual security requirements of the platform,
+if and how many of the CA functions are made available to the
+application through this device.
+
+All devices can be found in the ``/dev`` tree under ``/dev/dvb``. The
+individual devices are called:
+
+-  ``/dev/dvb/adapterN/audioM``,
+
+-  ``/dev/dvb/adapterN/videoM``,
+
+-  ``/dev/dvb/adapterN/frontendM``,
+
+-  ``/dev/dvb/adapterN/netM``,
+
+-  ``/dev/dvb/adapterN/demuxM``,
+
+-  ``/dev/dvb/adapterN/dvrM``,
+
+-  ``/dev/dvb/adapterN/caM``,
+
+where ``N`` enumerates the Digital TV cards in a system starting from 0, and
+``M`` enumerates the devices of each type within each adapter, starting
+from 0, too. We will omit the “``/dev/dvb/adapterN/``\ ” in the further
+discussion of these devices.
+
+More details about the data structures and function calls of all the
+devices are described in the following chapters.
+
+
+.. _include_files:
+
+API include files
+=================
+
+For each of the Digital TV devices a corresponding include file exists. The
+Digital TV API include files should be included in application sources with a
+partial path like:
+
+
+.. code-block:: c
+
+	#include <linux/dvb/ca.h>
+
+	#include <linux/dvb/dmx.h>
+
+	#include <linux/dvb/frontend.h>
+
+	#include <linux/dvb/net.h>
+
+
+To enable applications to support different API version, an additional
+include file ``linux/dvb/version.h`` exists, which defines the constant
+``DVB_API_VERSION``. This document describes ``DVB_API_VERSION 5.10``.

+Digital TV Network API
+######################
+
+The Digital TV net device controls the mapping of data packages that are part
+of a transport stream to be mapped into a virtual network interface,
+visible through the standard Linux network protocol stack.
+
+Currently, two encapsulations are supported:
+
+-  `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
+
+-  `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
+
+In order to create the Linux virtual network interfaces, an application
+needs to tell to the Kernel what are the PIDs and the encapsulation
+types that are present on the transport stream. This is done through
+``/dev/dvb/adapter?/net?`` device node. The data will be available via
+virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
+the standard ip tools (like ip, route, netstat, ifconfig, etc).
+
+Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
+header.

+Description
+-----------
+
+This system call opens a named video device (e.g.

+
+When an open() call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call. This is a standard
+system call, documented in the Linux manual page for fcntl. Only one
+user can open the Video Device in O_RDWR mode. All other attempts to
+open the device in this mode will fail, and an error-code will be
+returned. If the Video Device is opened in O_RDONLY mode, the only
+ioctl call that can be used is VIDEO_GET_STATUS. All other call will
+return an error code.

+Description
+-----------
+
+This ioctl is for Digital TV devices only. To control a V4L2 decoder use the
+V4L2 :ref:`VIDIOC_DECODER_CMD` instead.
+
+This ioctl call suspends the live video stream being played. Decoding
+and playing are frozen. It is then possible to restart the decoding and
+playing process of the video stream using the VIDEO_CONTINUE command.
+If VIDEO_SOURCE_MEMORY is selected in the ioctl call
+VIDEO_SELECT_SOURCE, the Digital TV subsystem will not decode any more data
+until the ioctl call VIDEO_CONTINUE or VIDEO_PLAY is performed.
+
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+Description
+-----------
+
+This ioctl is for Digital TV devices only. To get events from a V4L2 decoder
+use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
+
+This ioctl call returns an event of type video_event if available. If
+an event is not available, the behavior depends on whether the device is
+in blocking or non-blocking mode. In the latter case, the call fails
+immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
+blocks until an event becomes available. The standard Linux poll()
+and/or select() system calls can be used with the device file descriptor
+to watch for new events. For select(), the file descriptor should be
+included in the exceptfds argument, and for poll(), POLLPRI should be
+specified as the wake-up condition. Read-only permissions are sufficient
+for this ioctl call.

+Digital TV Video Device
+#######################
+
+The Digital TV video device controls the MPEG2 video decoder of the Digital
+TV hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
+types and and ioctl definitions can be accessed by including
+**linux/dvb/video.h** in your application.
+
+Note that the Digital TV video device only controls decoding of the MPEG video
+stream, not its presentation on the TV or computer screen. On PCs this
+is typically handled by an associated video4linux device, e.g.
+**/dev/video**, which allows scaling and defining output windows.
+
+Some Digital TV cards don’t have their own MPEG decoder, which results in the
+omission of the audio and video device as well as the video4linux
+device.
+
+The ioctls that deal with SPUs (sub picture units) and navigation
+packets are only supported on some MPEG decoders made for DVD playback.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+
+****************
+Video Data Types
+****************
+
+
+.. _video-format-t:
+
+video_format_t
+==============
+
+The ``video_format_t`` data type defined by
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_FORMAT_4_3,     /* Select 4:3 format */
+	VIDEO_FORMAT_16_9,    /* Select 16:9 format. */
+	VIDEO_FORMAT_221_1    /* 2.21:1 */
+    } video_format_t;
+
+is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
+aspect ratio the output hardware (e.g. TV) has. It is also used in the
+data structures video_status (??) returned by VIDEO_GET_STATUS (??)
+and video_event (??) returned by VIDEO_GET_EVENT (??) which report
+about the display format of the current video stream.
+
+
+.. _video-displayformat-t:
+
+video_displayformat_t
+=====================
+
+In case the display format of the video stream and of the display
+hardware differ the application has to specify how to handle the
+cropping of the picture. This can be done using the
+VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_PAN_SCAN,       /* use pan and scan format */
+	VIDEO_LETTER_BOX,     /* use letterbox format */
+	VIDEO_CENTER_CUT_OUT  /* use center cut out format */
+    } video_displayformat_t;
+
+as argument.
+
+
+.. _video-stream-source-t:
+
+video_stream_source_t
+=====================
+
+The video stream source is set through the VIDEO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demuxer) or external (user write) source.
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
+	VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
+		       comes from the user through the write
+		       system call */
+    } video_stream_source_t;
+
+VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+VIDEO_SOURCE_MEMORY is selected the stream comes from the application
+through the **write()** system call.
+
+
+.. _video-play-state-t:
+
+video_play_state_t
+==================
+
+The following values can be returned by the VIDEO_GET_STATUS call
+representing the state of video playback.
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_STOPPED, /* Video is stopped */
+	VIDEO_PLAYING, /* Video is currently playing */
+	VIDEO_FREEZED  /* Video is freezed */
+    } video_play_state_t;
+
+
+.. c:type:: video_command
+
+struct video_command
+====================
+
+The structure must be zeroed before use by the application This ensures
+it can be extended safely in the future.
+
+
+.. code-block:: c
+
+    struct video_command {
+	__u32 cmd;
+	__u32 flags;
+	union {
+	    struct {
+		__u64 pts;
+	    } stop;
+
+	    struct {
+		/* 0 or 1000 specifies normal speed,
+		   1 specifies forward single stepping,
+		   -1 specifies backward single stepping,
+		   >>1: playback at speed/1000 of the normal speed,
+		   <-1: reverse playback at (-speed/1000) of the normal speed. */
+		__s32 speed;
+		__u32 format;
+	    } play;
+
+	    struct {
+		__u32 data[16];
+	    } raw;
+	};
+    };
+
+
+.. _video-size-t:
+
+video_size_t
+============
+
+
+.. code-block:: c
+
+    typedef struct {
+	int w;
+	int h;
+	video_format_t aspect_ratio;
+    } video_size_t;
+
+
+.. c:type:: video_event
+
+struct video_event
+==================
+
+The following is the structure of a video event as it is returned by the
+VIDEO_GET_EVENT call.
+
+
+.. code-block:: c
+
+    struct video_event {
+	__s32 type;
+    #define VIDEO_EVENT_SIZE_CHANGED    1
+    #define VIDEO_EVENT_FRAME_RATE_CHANGED  2
+    #define VIDEO_EVENT_DECODER_STOPPED     3
+    #define VIDEO_EVENT_VSYNC       4
+	long timestamp;
+	union {
+	    video_size_t size;
+	    unsigned int frame_rate;    /* in frames per 1000sec */
+	    unsigned char vsync_field;  /* unknown/odd/even/progressive */
+	} u;
+    };
+
+
+.. c:type:: video_status
+
+struct video_status
+===================
+
+The VIDEO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+    struct video_status {
+	int                   video_blank;   /* blank video on freeze? */
+	video_play_state_t    play_state;    /* current state of playback */
+	video_stream_source_t stream_source; /* current source (demux/memory) */
+	video_format_t        video_format;  /* current aspect ratio of stream */
+	video_displayformat_t display_format;/* selected cropping mode */
+    };
+
+If video_blank is set video will be blanked out if the channel is
+changed or if playback is stopped. Otherwise, the last picture will be
+displayed. play_state indicates if the video is currently frozen,
+stopped, or being played back. The stream_source corresponds to the
+selected source for the video stream. It can come either from the
+demultiplexer or from memory. The video_format indicates the aspect
+ratio (one of 4:3 or 16:9) of the currently played video stream.
+Finally, display_format corresponds to the selected cropping mode in
+case the source video format is not the same as the format of the output
+device.
+
+
+.. c:type:: video_still_picture
+
+struct video_still_picture
+==========================
+
+An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
+within the following structure.
+
+
+.. code-block:: c
+
+    /* pointer to and size of a single iframe in memory */
+    struct video_still_picture {
+	char *iFrame;        /* pointer to a single iframe in memory */
+	int32_t size;
+    };
+
+
+.. _video_caps:
+
+video capabilities
+==================
+
+A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
+following bits set according to the hardwares capabilities.
+
+
+.. code-block:: c
+
+     /* bit definitions for capabilities: */
+     /* can the hardware decode MPEG1 and/or MPEG2? */
+     #define VIDEO_CAP_MPEG1   1
+     #define VIDEO_CAP_MPEG2   2
+     /* can you send a system and/or program stream to video device?
+	(you still have to open the video and the audio device but only
+	 send the stream to the video device) */
+     #define VIDEO_CAP_SYS     4
+     #define VIDEO_CAP_PROG    8
+     /* can the driver also handle SPU, NAVI and CSS encoded data?
+	(CSS API is not present yet) */
+     #define VIDEO_CAP_SPU    16
+     #define VIDEO_CAP_NAVI   32
+     #define VIDEO_CAP_CSS    64

+
+
+.. _fdl-preamble:
+
+0. PREAMBLE
+===========
+
+The purpose of this License is to make a manual, textbook, or other
+written document “free” in the sense of freedom: to assure everyone the
+effective freedom to copy and redistribute it, with or without modifying
+it, either commercially or noncommercially. Secondarily, this License
+preserves for the author and publisher a way to get credit for their
+work, while not being considered responsible for modifications made by
+others.
+
+This License is a kind of “copyleft”, which means that derivative works
+of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft license
+designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free program
+should come with manuals providing the same freedoms that the software
+does. But this License is not limited to software manuals; it can be
+used for any textual work, regardless of subject matter or whether it is
+published as a printed book. We recommend this License principally for
+works whose purpose is instruction or reference.
+
+
+.. _fdl-section1:
+
+1. APPLICABILITY AND DEFINITIONS
+================================
+
+
+.. _fdl-document:
+
+This License applies to any manual or other work that contains a notice
+placed by the copyright holder saying it can be distributed under the
+terms of this License. The “Document”, below, refers to any such manual
+or work. Any member of the public is a licensee, and is addressed as
+“you”.
+
+
+.. _fdl-modified:
+
+A “Modified Version” of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+
+.. _fdl-secondary:
+
+A “Secondary Section” is a named appendix or a front-matter section of
+the :ref:`Document <fdl-document>` that deals exclusively with the
+relationship of the publishers or authors of the Document to the
+Document's overall subject (or to related matters) and contains nothing
+that could fall directly within that overall subject. (For example, if
+the Document is in part a textbook of mathematics, a Secondary Section
+may not explain any mathematics.) The relationship could be a matter of
+historical connection with the subject or with related matters, or of
+legal, commercial, philosophical, ethical or political position
+regarding them.
+
+
+.. _fdl-invariant:
+
+The “Invariant Sections” are certain
+:ref:`Secondary Sections <fdl-secondary>` whose titles are designated,
+as being those of Invariant Sections, in the notice that says that the
+:ref:`Document <fdl-document>` is released under this License.
+
+
+.. _fdl-cover-texts:
+
+The “Cover Texts” are certain short passages of text that are listed, as
+Front-Cover Texts or Back-Cover Texts, in the notice that says that the
+:ref:`Document <fdl-document>` is released under this License.
+
+
+.. _fdl-transparent:
+
+A “Transparent” copy of the :ref:`Document <fdl-document>` means a
+machine-readable copy, represented in a format whose specification is
+available to the general public, whose contents can be viewed and edited
+directly and straightforwardly with generic text editors or (for images
+composed of pixels) generic paint programs or (for drawings) some widely
+available drawing editor, and that is suitable for input to text
+formatters or for automatic translation to a variety of formats suitable
+for input to text formatters. A copy made in an otherwise Transparent
+file format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent. A copy that is
+not “Transparent” is called “Opaque”.
+
+Examples of suitable formats for Transparent copies include plain ASCII
+without markup, Texinfo input format, LaTeX input format, SGML or XML
+using a publicly available DTD, and standard-conforming simple HTML
+designed for human modification. Opaque formats include PostScript, PDF,
+proprietary formats that can be read and edited only by proprietary word
+processors, SGML or XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML produced by some
+word processors for output purposes only.
+
+
+.. _fdl-title-page:
+
+The “Title Page” means, for a printed book, the title page itself, plus
+such following pages as are needed to hold, legibly, the material this
+License requires to appear in the title page. For works in formats which
+do not have any title page as such, “Title Page” means the text near the
+most prominent appearance of the work's title, preceding the beginning
+of the body of the text.
+
+
+.. _fdl-section2:
+
+2. VERBATIM COPYING
+===================
+
+You may copy and distribute the :ref:`Document <fdl-document>` in any
+medium, either commercially or noncommercially, provided that this
+License, the copyright notices, and the license notice saying this
+License applies to the Document are reproduced in all copies, and that
+you add no other conditions whatsoever to those of this License. You may
+not use technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in
+:ref:`section 3 <fdl-section3>`.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+.. _fdl-section3:
+
+3. COPYING IN QUANTITY
+======================
+
+If you publish printed copies of the :ref:`Document <fdl-document>`
+numbering more than 100, and the Document's license notice requires
+:ref:`Cover Texts <fdl-cover-texts>`, you must enclose the copies in
+covers that carry, clearly and legibly, all these Cover Texts:
+Front-Cover Texts on the front cover, and Back-Cover Texts on the back
+cover. Both covers must also clearly and legibly identify you as the
+publisher of these copies. The front cover must present the full title
+with all words of the title equally prominent and visible. You may add
+other material on the covers in addition. Copying with changes limited
+to the covers, as long as they preserve the title of the
+:ref:`Document <fdl-document>` and satisfy these conditions, can be
+treated as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute :ref:`Opaque <fdl-transparent>` copies of
+the :ref:`Document <fdl-document>` numbering more than 100, you must
+either include a machine-readable :ref:`Transparent <fdl-transparent>`
+copy along with each Opaque copy, or state in or with each Opaque copy a
+publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols. If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+:ref:`Document <fdl-document>` well before redistributing any large
+number of copies, to give them a chance to provide you with an updated
+version of the Document.
+
+
+.. _fdl-section4:
+
+4. MODIFICATIONS
+================
+
+You may copy and distribute a :ref:`Modified Version <fdl-modified>`
+of the :ref:`Document <fdl-document>` under the conditions of sections
+:ref:`2 <fdl-section2>` and :ref:`3 <fdl-section3>` above, provided
+that you release the Modified Version under precisely this License, with
+the Modified Version filling the role of the Document, thus licensing
+distribution and modification of the Modified Version to whoever
+possesses a copy of it. In addition, you must do these things in the
+Modified Version:
+
+-  **A.**
+   Use in the :ref:`Title Page <fdl-title-page>` (and on the covers,
+   if any) a title distinct from that of the
+   :ref:`Document <fdl-document>`, and from those of previous versions
+   (which should, if there were any, be listed in the History section of
+   the Document). You may use the same title as a previous version if
+   the original publisher of that version gives permission.
+
+-  **B.**
+   List on the :ref:`Title Page <fdl-title-page>`, as authors, one or
+   more persons or entities responsible for authorship of the
+   modifications in the :ref:`Modified Version <fdl-modified>`,
+   together with at least five of the principal authors of the
+   :ref:`Document <fdl-document>` (all of its principal authors, if it
+   has less than five).
+
+-  **C.**
+   State on the :ref:`Title Page <fdl-title-page>` the name of the
+   publisher of the :ref:`Modified Version <fdl-modified>`, as the
+   publisher.
+
+-  **D.**
+   Preserve all the copyright notices of the
+   :ref:`Document <fdl-document>`.
+
+-  **E.**
+   Add an appropriate copyright notice for your modifications adjacent
+   to the other copyright notices.
+
+-  **F.**
+   Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the
+   :ref:`Modified Version <fdl-modified>` under the terms of this
+   License, in the form shown in the Addendum below.
+
+-  **G.**
+   Preserve in that license notice the full lists of
+   :ref:`Invariant Sections <fdl-invariant>` and required
+   :ref:`Cover Texts <fdl-cover-texts>` given in the
+   :ref:`Document's <fdl-document>` license notice.
+
+-  **H.**
+   Include an unaltered copy of this License.
+
+-  **I.**
+   Preserve the section entitled “History”, and its title, and add to it
+   an item stating at least the title, year, new authors, and publisher
+   of the :ref:`Modified Version <fdl-modified>` as given on the
+   :ref:`Title Page <fdl-title-page>`. If there is no section entitled
+   “History” in the :ref:`Document <fdl-document>`, create one stating
+   the title, year, authors, and publisher of the Document as given on
+   its Title Page, then add an item describing the Modified Version as
+   stated in the previous sentence.
+
+-  **J.**
+   Preserve the network location, if any, given in the
+   :ref:`Document <fdl-document>` for public access to a
+   :ref:`Transparent <fdl-transparent>` copy of the Document, and
+   likewise the network locations given in the Document for previous
+   versions it was based on. These may be placed in the “History”
+   section. You may omit a network location for a work that was
+   published at least four years before the Document itself, or if the
+   original publisher of the version it refers to gives permission.
+
+-  **K.**
+   In any section entitled “Acknowledgements” or “Dedications”, preserve
+   the section's title, and preserve in the section all the substance
+   and tone of each of the contributor acknowledgements and/or
+   dedications given therein.
+
+-  **L.**
+   Preserve all the :ref:`Invariant Sections <fdl-invariant>` of the
+   :ref:`Document <fdl-document>`, unaltered in their text and in
+   their titles. Section numbers or the equivalent are not considered
+   part of the section titles.
+
+-  **M.**
+   Delete any section entitled “Endorsements”. Such a section may not be
+   included in the :ref:`Modified Version <fdl-modified>`.
+
+-  **N.**
+   Do not retitle any existing section as “Endorsements” or to conflict
+   in title with any :ref:`Invariant Section <fdl-invariant>`.
+
+If the :ref:`Modified Version <fdl-modified>` includes new
+front-matter sections or appendices that qualify as
+:ref:`Secondary Sections <fdl-secondary>` and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the list
+of :ref:`Invariant Sections <fdl-invariant>` in the Modified Version's
+license notice. These titles must be distinct from any other section
+titles.
+
+You may add a section entitled “Endorsements”, provided it contains
+nothing but endorsements of your
+:ref:`Modified Version <fdl-modified>` by various parties--for
+example, statements of peer review or that the text has been approved by
+an organization as the authoritative definition of a standard.
+
+You may add a passage of up to five words as a
+:ref:`Front-Cover Text <fdl-cover-texts>`, and a passage of up to 25
+words as a :ref:`Back-Cover Text <fdl-cover-texts>`, to the end of the
+list of :ref:`Cover Texts <fdl-cover-texts>` in the
+:ref:`Modified Version <fdl-modified>`. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or through
+arrangements made by) any one entity. If the
+:ref:`Document <fdl-document>` already includes a cover text for the
+same cover, previously added by you or by arrangement made by the same
+entity you are acting on behalf of, you may not add another; but you may
+replace the old one, on explicit permission from the previous publisher
+that added the old one.
+
+The author(s) and publisher(s) of the :ref:`Document <fdl-document>`
+do not by this License give permission to use their names for publicity
+for or to assert or imply endorsement of any
+:ref:`Modified Version <fdl-modified>`.
+
+
+.. _fdl-section5:
+
+5. COMBINING DOCUMENTS
+======================
+
+You may combine the :ref:`Document <fdl-document>` with other
+documents released under this License, under the terms defined in
+:ref:`section 4 <fdl-section4>` above for modified versions, provided
+that you include in the combination all of the
+:ref:`Invariant Sections <fdl-invariant>` of all of the original
+documents, unmodified, and list them all as Invariant Sections of your
+combined work in its license notice.
+
+The combined work need only contain one copy of this License, and
+multiple identical :ref:`Invariant Sections <fdl-invariant>` may be
+replaced with a single copy. If there are multiple Invariant Sections
+with the same name but different contents, make the title of each such
+section unique by adding at the end of it, in parentheses, the name of
+the original author or publisher of that section if known, or else a
+unique number. Make the same adjustment to the section titles in the
+list of Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections entitled “History” in
+the various original documents, forming one section entitled “History”;
+likewise combine any sections entitled “Acknowledgements”, and any
+sections entitled “Dedications”. You must delete all sections entitled
+“Endorsements.”
+
+
+.. _fdl-section6:
+
+6. COLLECTIONS OF DOCUMENTS
+===========================
+
+You may make a collection consisting of the
+:ref:`Document <fdl-document>` and other documents released under this
+License, and replace the individual copies of this License in the
+various documents with a single copy that is included in the collection,
+provided that you follow the rules of this License for verbatim copying
+of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+.. _fdl-section7:
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+=====================================
+
+A compilation of the :ref:`Document <fdl-document>` or its derivatives
+with other separate and independent documents or works, in or on a
+volume of a storage or distribution medium, does not as a whole count as
+a :ref:`Modified Version <fdl-modified>` of the Document, provided no
+compilation copyright is claimed for the compilation. Such a compilation
+is called an “aggregate”, and this License does not apply to the other
+self-contained works thus compiled with the Document , on account of
+their being thus compiled, if they are not themselves derivative works
+of the Document. If the :ref:`Cover Text <fdl-cover-texts>`
+requirement of :ref:`section 3 <fdl-section3>` is applicable to these
+copies of the Document, then if the Document is less than one quarter of
+the entire aggregate, the Document's Cover Texts may be placed on covers
+that surround only the Document within the aggregate. Otherwise they
+must appear on covers around the whole aggregate.
+
+
+.. _fdl-section8:
+
+8. TRANSLATION
+==============
+
+Translation is considered a kind of modification, so you may distribute
+translations of the :ref:`Document <fdl-document>` under the terms of
+:ref:`section 4 <fdl-section4>`. Replacing
+:ref:`Invariant Sections <fdl-invariant>` with translations requires
+special permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License provided that you also include the original
+English version of this License. In case of a disagreement between the
+translation and the original English version of this License, the
+original English version will prevail.
+
+
+.. _fdl-section9:
+
+9. TERMINATION
+==============
+
+You may not copy, modify, sublicense, or distribute the
+:ref:`Document <fdl-document>` except as expressly provided for under
+this License. Any other attempt to copy, modify, sublicense or
+distribute the Document is void, and will automatically terminate your
+rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+
+.. _fdl-section10:
+
+10. FUTURE REVISIONS OF THIS LICENSE
+====================================
+
+The `Free Software Foundation <http://www.gnu.org/fsf/fsf.html>`__
+may publish new, revised versions of the GNU Free Documentation License
+from time to time. Such new versions will be similar in spirit to the
+present version, but may differ in detail to address new problems or
+concerns. See
+`http://www.gnu.org/copyleft/ <http://www.gnu.org/copyleft>`__.
+
+Each version of the License is given a distinguishing version number. If
+the :ref:`Document <fdl-document>` specifies that a particular
+numbered version of this License “or any later version” applies to it,
+you have the option of following the terms and conditions either of that
+specified version or of any later version that has been published (not
+as a draft) by the Free Software Foundation. If the Document does not
+specify a version number of this License, you may choose any version
+ever published (not as a draft) by the Free Software Foundation.
+
+
+.. _fdl-using:
+
+Addendum
+========
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+

+
+
+    -  -  ``EAGAIN`` (aka ``EWOULDBLOCK``)
+
+       -  The ioctl can't be handled because the device is in state where it
+	  can't perform it. This could happen for example in case where
+	  device is sleeping and ioctl is performed to query statistics. It
+	  is also returned when the ioctl would need to wait for an event,
+	  but the device was opened in non-blocking mode.
+
+    -  -  ``EBADF``
+
+       -  The file descriptor is not a valid.
+
+    -  -  ``EBUSY``
+
+       -  The ioctl can't be handled because the device is busy. This is
+	  typically return while device is streaming, and an ioctl tried to
+	  change something that would affect the stream, or would require
+	  the usage of a hardware resource that was already allocated. The
+	  ioctl must not be retried without performing another action to fix
+	  the problem first (typically: stop the stream before retrying).
+
+    -  -  ``EFAULT``
+
+       -  There was a failure while copying data from/to userspace, probably
+	  caused by an invalid pointer reference.
+
+    -  -  ``EINVAL``
+
+       -  One or more of the ioctl parameters are invalid or out of the
+	  allowed range. This is a widely used error code. See the
+	  individual ioctl requests for specific causes.
+
+    -  -  ``ENODEV``
+
+       -  Device not found or was removed.
+
+    -  -  ``ENOMEM``
+
+       -  There's not enough memory to handle the desired operation.
+
+    -  -  ``ENOTTY``
+
+       -  The ioctl is not supported by the driver, actually meaning that
+	  the required functionality is not available, or the file
+	  descriptor is not for a media device.
+
+    -  -  ``ENOSPC``
+
+       -  On USB devices, the stream ioctl's can return this error, meaning
+	  that this request would overcommit the usb bandwidth reserved for
+	  periodic transfers (up to 80% of the USB bandwidth).
+
+    -  -  ``EPERM``
+
+       -  Permission denied. Can be returned if the device needs write
+	  permission, or some special capabilities is needed (e. g. root)
+
+    -  -  ``EIO``
+
+       -  I/O error. Typically used when there are problems communicating with
+          a hardware device. This could indicate broken or flaky hardware.
+	  It's a 'Something is wrong, I give up!' type of error.
+
+    -  - ``ENXIO``

+Introduction
+============
+
+Media devices increasingly handle multiple related functions. Many USB
+cameras include microphones, video capture hardware can also output
+video, or SoC camera interfaces also perform memory-to-memory operations
+similar to video codecs.
+
+Independent functions, even when implemented in the same hardware, can
+be modelled as separate devices. A USB camera with a microphone will be
+presented to userspace applications as V4L2 and ALSA capture devices.
+The devices' relationships (when using a webcam, end-users shouldn't
+have to manually select the associated USB microphone), while not made
+available directly to applications by the drivers, can usually be
+retrieved from sysfs.
+
+With more and more advanced SoC devices being introduced, the current
+approach will not scale. Device topologies are getting increasingly
+complex and can't always be represented by a tree structure. Hardware
+blocks are shared between different functions, creating dependencies
+between seemingly unrelated devices.
+
+Kernel abstraction APIs such as V4L2 and ALSA provide means for
+applications to access hardware parameters. As newer hardware expose an
+increasingly high number of those parameters, drivers need to guess what
+applications really require based on limited information, thereby
+implementing policies that belong to userspace.
+
+The media controller API aims at solving those problems.

+
+Media device model
+==================
+
+Discovering a device internal topology, and configuring it at runtime,
+is one of the goals of the media controller API. To achieve this,
+hardware devices and Linux Kernel interfaces are modelled as graph
+objects on an oriented graph. The object types that constitute the graph
+are:
+
+-  An **entity** is a basic media hardware or software building block.
+   It can correspond to a large variety of logical blocks such as
+   physical hardware devices (CMOS sensor for instance), logical
+   hardware devices (a building block in a System-on-Chip image
+   processing pipeline), DMA channels or physical connectors.
+
+-  An **interface** is a graph representation of a Linux Kernel
+   userspace API interface, like a device node or a sysfs file that
+   controls one or more entities in the graph.
+
+-  A **pad** is a data connection endpoint through which an entity can
+   interact with other entities. Data (not restricted to video) produced
+   by an entity flows from the entity's output to one or more entity
+   inputs. Pads should not be confused with physical pins at chip
+   boundaries.
+
+-  A **data link** is a point-to-point oriented connection between two
+   pads, either on the same entity or on different entities. Data flows
+   from a source pad to a sink pad.
+
+-  An **interface link** is a point-to-point bidirectional control
+   connection between a Linux Kernel interface and an entity.

+
+``argp``
+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+The :ref:`ioctl() <media-func-ioctl>` function manipulates media device
+parameters. The argument ``fd`` must be an open file descriptor.
+
+The ioctl ``request`` code specifies the media function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying media ioctl requests and
+their parameters are located in the media.h header file. All media ioctl
+requests, their respective function and parameters are specified in
+:ref:`media-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Request-specific error codes are listed in the individual requests
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+
+Description
+===========
+
+All media devices must support the ``MEDIA_IOC_DEVICE_INFO`` ioctl. To
+query device information, applications call the ioctl with a pointer to
+a struct :c:type:`media_device_info`. The driver
+fills the structure and returns the information to the application. The
+ioctl never fails.

+    *  -  char
+       -  ``driver``\ [16]
+       -  Name of the driver implementing the media API as a NUL-terminated
+	  ASCII string. The driver version is stored in the
+	  ``driver_version`` field.
+
+	  Driver specific applications can use this information to verify
+	  the driver identity. It is also useful to work around known bugs,
+	  or to identify drivers in error reports.
+
+    *  -  char
+       -  ``model``\ [32]
+       -  Device model name as a NUL-terminated UTF-8 string. The device
+	  version is stored in the ``device_version`` field and is not be
+	  appended to the model name.
+
+    *  -  char
+       -  ``serial``\ [40]
+       -  Serial number as a NUL-terminated ASCII string.
+
+    *  -  char
+       -  ``bus_info``\ [32]
+       -  Location of the device in the system as a NUL-terminated ASCII
+	  string. This includes the bus type name (PCI, USB, ...) and a
+	  bus-specific identifier.
+
+    *  -  __u32
+       -  ``media_version``
+       -  Media API version, formatted with the ``KERNEL_VERSION()`` macro.
+
+    *  -  __u32
+       -  ``hw_revision``
+       -  Hardware device revision in a driver-specific format.
+
+    *  -  __u32
+       -  ``driver_version``
+       -  Media device driver version, formatted with the
+	  ``KERNEL_VERSION()`` macro. Together with the ``driver`` field
+	  this identifies a particular driver.
+
+    *  -  __u32
+       -  ``reserved``\ [31]
+       -  Reserved for future extensions. Drivers and applications must set
+	  this array to zero.
+
+
+The ``serial`` and ``bus_info`` fields can be used to distinguish
+between multiple instances of otherwise identical hardware. The serial
+number takes precedence when provided and can be assumed to be unique.
+If the serial number is an empty string, the ``bus_info`` field can be
+used instead. The ``bus_info`` field is guaranteed to be unique, but can
+vary across reboots or device unplug/replug.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+To query the attributes of an entity, applications set the id field of a

+one ('next entity'), or the ``EINVAL`` error code if there is none.
+

+Description
+===========
+
+To enumerate pads and/or links for a given entity, applications set the

+MEDIA_IOC_ENUM_LINKS ioctl with a pointer to this structure.
+
+If the ``pads`` field is not NULL, the driver fills the ``pads`` array
+with information about the entity's pads. The array must have enough
+room to store all the entity's pads. The number of pads can be retrieved
+with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
+
+If the ``links`` field is not NULL, the driver fills the ``links`` array
+with information about the entity's outbound links. The array must have
+enough room to store all the entity's outbound links. The number of
+outbound links can be retrieved with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
+
+Only forward links that originate at one of the entity's source pads are

+
+``argp``
+    Pointer to struct :c:type:`media_v2_topology`.
+
+
+Description
+===========
+
+The typical usage of this ioctl is to call it twice. On the first call,
+the structure defined at struct
+:c:type:`media_v2_topology` should be zeroed. At
+return, if no errors happen, this ioctl will return the
+``topology_version`` and the total number of entities, interfaces, pads
+and links.
+
+Before the second call, the userspace should allocate arrays to store
+the graph elements that are desired, putting the pointers to them at the
+ptr_entities, ptr_interfaces, ptr_links and/or ptr_pads, keeping the
+other values untouched.
+
+If the ``topology_version`` remains the same, the ioctl should fill the
+desired arrays with the media graph elements.

+    Pointer to an integer.
+
+
+Description
+===========
+
+If the media device supports :ref:`requests <media-request-api>`, then
+this ioctl can be used to allocate a request. If it is not supported, then
+``errno`` is set to ``ENOTTY``. A request is accessed through a file descriptor
+that is returned in ``*argp``.
+
+If the request was successfully allocated, then the request file descriptor
+can be passed to the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctls.
+
+In addition, the request can be queued by calling
+:ref:`MEDIA_REQUEST_IOC_QUEUE` and re-initialized by calling
+:ref:`MEDIA_REQUEST_IOC_REINIT`.
+
+Finally, the file descriptor can be :ref:`polled <request-func-poll>` to wait
+for the request to complete.
+
+The request will remain allocated until all the file descriptors associated
+with it are closed by :ref:`close() <request-func-close>` and the driver no
+longer uses the request internally. See also
+:ref:`here <media-request-life-time>` for more information.

+    Pointer to struct :c:type:`media_link_desc`.
+
+
+Description
+===========
+
+To change link properties applications fill a struct
+:c:type:`media_link_desc` with link identification
+information (source and sink pad) and the new requested link flags. They
+then call the MEDIA_IOC_SETUP_LINK ioctl with a pointer to that
+structure.
+
+The only configurable property is the ``ENABLED`` link flag to
+enable/disable a link. Links marked with the ``IMMUTABLE`` link flag can
+not be enabled or disabled.
+
+Link configuration has no side effect on other links. If an enabled link
+at the sink pad prevents the link from being enabled, the driver returns
+with an ``EBUSY`` error code.
+
+Only links marked with the ``DYNAMIC`` link flag can be enabled/disabled
+while streaming media data. Attempting to enable or disable a streaming
+non-dynamic link will return an ``EBUSY`` error code.
+
+If the specified link can't be found the driver returns with an ``EINVAL``
+error code.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+
+EINVAL
+    The struct :c:type:`media_link_desc` references a

+    :name: MEDIA_REQUEST_IOC_QUEUE
+

+    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
+
+
+Description
+===========
+
+If the media device supports :ref:`requests <media-request-api>`, then
+this request ioctl can be used to queue a previously allocated request.
+
+If the request was successfully queued, then the file descriptor can be
+:ref:`polled <request-func-poll>` to wait for the request to complete.
+
+If the request was already queued before, then ``EBUSY`` is returned.
+Other errors can be returned if the contents of the request contained
+invalid or inconsistent data, see the next section for a list of
+common error codes. On error both the request and driver state are unchanged.
+
+Once a request is queued, then the driver is required to gracefully handle
+errors that occur when the request is applied to the hardware. The
+exception is the ``EIO`` error which signals a fatal error that requires
+the application to stop streaming to reset the hardware state.
+
+It is not allowed to mix queuing requests with queuing buffers directly
+(without a request). ``EBUSY`` will be returned if the first buffer was
+queued directly and you next try to queue a request, or vice versa.
+
+A request must contain at least one buffer, otherwise this ioctl will
+return an ``ENOENT`` error.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EBUSY
+    The request was already queued or the application queued the first
+    buffer directly, but later attempted to use a request. It is not permitted
+    to mix the two APIs.
+ENOENT
+    The request did not contain any buffers. All requests are required
+    to have at least one buffer. This can also be returned if some required
+    configuration is missing in the request.
+ENOMEM
+    Out of memory when allocating internal data structures for this
+    request.
+EINVAL
+    The request has invalid data.
+EIO
+    The hardware is in a bad state. To recover, the application needs to
+    stop streaming to reset the hardware state and then try to restart
+    streaming.

+
+MEDIA_REQUEST_IOC_REINIT - Re-initialize a request
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int request_fd, MEDIA_REQUEST_IOC_REINIT )
+    :name: MEDIA_REQUEST_IOC_REINIT
+
+
+Arguments
+=========
+
+``request_fd``
+    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
+
+Description
+===========
+
+If the media device supports :ref:`requests <media-request-api>`, then
+this request ioctl can be used to re-initialize a previously allocated
+request.
+
+Re-initializing a request will clear any existing data from the request.
+This avoids having to :ref:`close() <request-func-close>` a completed
+request and allocate a new request. Instead the completed request can just
+be re-initialized and it is ready to be used again.
+
+A request can only be re-initialized if it either has not been queued
+yet, or if it was queued and completed. Otherwise it will set ``errno``
+to ``EBUSY``. No other error codes can be returned.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately.
+
+EBUSY
+    The request is queued but not yet completed.

+Request API
+===========
+
+The Request API has been designed to allow V4L2 to deal with requirements of
+modern devices (stateless codecs, complex camera pipelines, ...) and APIs
+(Android Codec v2). One such requirement is the ability for devices belonging to
+the same pipeline to reconfigure and collaborate closely on a per-frame basis.
+Another is support of stateless codecs, which require controls to be applied
+to specific frames (aka 'per-frame controls') in order to be used efficiently.
+
+While the initial use-case was V4L2, it can be extended to other subsystems
+as well, as long as they use the media controller.
+
+Supporting these features without the Request API is not always possible and if
+it is, it is terribly inefficient: user-space would have to flush all activity
+on the media pipeline, reconfigure it for the next frame, queue the buffers to
+be processed with that configuration, and wait until they are all available for
+dequeuing before considering the next frame. This defeats the purpose of having
+buffer queues since in practice only one buffer would be queued at a time.
+
+The Request API allows a specific configuration of the pipeline (media
+controller topology + configuration for each media entity) to be associated with
+specific buffers. This allows user-space to schedule several tasks ("requests")
+with different configurations in advance, knowing that the configuration will be
+applied when needed to get the expected result. Configuration values at the time
+of request completion are also available for reading.
+
+General Usage
+-------------
+
+The Request API extends the Media Controller API and cooperates with
+subsystem-specific APIs to support request usage. At the Media Controller
+level, requests are allocated from the supporting Media Controller device
+node. Their life cycle is then managed through the request file descriptors in
+an opaque way. Configuration data, buffer handles and processing results
+stored in requests are accessed through subsystem-specific APIs extended for
+request support, such as V4L2 APIs that take an explicit ``request_fd``
+parameter.
+
+Request Allocation
+------------------
+
+User-space allocates requests using :ref:`MEDIA_IOC_REQUEST_ALLOC`
+for the media device node. This returns a file descriptor representing the
+request. Typically, several such requests will be allocated.
+
+Request Preparation
+-------------------
+
+Standard V4L2 ioctls can then receive a request file descriptor to express the
+fact that the ioctl is part of said request, and is not to be applied
+immediately. See :ref:`MEDIA_IOC_REQUEST_ALLOC` for a list of ioctls that
+support this. Configurations set with a ``request_fd`` parameter are stored
+instead of being immediately applied, and buffers queued to a request do not
+enter the regular buffer queue until the request itself is queued.
+
+Request Submission
+------------------
+
+Once the configuration and buffers of the request are specified, it can be
+queued by calling :ref:`MEDIA_REQUEST_IOC_QUEUE` on the request file descriptor.
+A request must contain at least one buffer, otherwise ``ENOENT`` is returned.
+A queued request cannot be modified anymore.
+
+.. caution::
+   For :ref:`memory-to-memory devices <mem2mem>` you can use requests only for
+   output buffers, not for capture buffers. Attempting to add a capture buffer
+   to a request will result in an ``EBADR`` error.
+
+If the request contains configurations for multiple entities, individual drivers
+may synchronize so the requested pipeline's topology is applied before the
+buffers are processed. Media controller drivers do a best effort implementation
+since perfect atomicity may not be possible due to hardware limitations.
+
+.. caution::
+
+   It is not allowed to mix queuing requests with directly queuing buffers:
+   whichever method is used first locks this in place until
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called or the device is
+   :ref:`closed <func-close>`. Attempts to directly queue a buffer when earlier
+   a buffer was queued via a request or vice versa will result in an ``EBUSY``
+   error.
+
+Controls can still be set without a request and are applied immediately,
+regardless of whether a request is in use or not.
+
+.. caution::
+
+   Setting the same control through a request and also directly can lead to
+   undefined behavior!
+
+User-space can :ref:`poll() <request-func-poll>` a request file descriptor in
+order to wait until the request completes. A request is considered complete
+once all its associated buffers are available for dequeuing and all the
+associated controls have been updated with the values at the time of completion.
+Note that user-space does not need to wait for the request to complete to
+dequeue its buffers: buffers that are available halfway through a request can
+be dequeued independently of the request's state.
+
+A completed request contains the state of the device after the request was
+executed. User-space can query that state by calling
+:ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` with the request file
+descriptor. Calling :ref:`ioctl VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
+request that has been queued but not yet completed will return ``EBUSY``
+since the control values might be changed at any time by the driver while the
+request is in flight.
+
+.. _media-request-life-time:
+
+Recycling and Destruction
+-------------------------
+
+Finally, a completed request can either be discarded or be reused. Calling
+:ref:`close() <request-func-close>` on a request file descriptor will make
+that file descriptor unusable and the request will be freed once it is no
+longer in use by the kernel. That is, if the request is queued and then the
+file descriptor is closed, then it won't be freed until the driver completed
+the request.
+
+The :ref:`MEDIA_REQUEST_IOC_REINIT` will clear a request's state and make it
+available again. No state is retained by this operation: the request is as
+if it had just been allocated.
+
+Example for a Codec Device
+--------------------------
+
+For use-cases such as :ref:`codecs <mem2mem>`, the request API can be used
+to associate specific controls to
+be applied by the driver for the OUTPUT buffer, allowing user-space
+to queue many such buffers in advance. It can also take advantage of requests'
+ability to capture the state of controls when the request completes to read back
+information that may be subject to change.
+
+Put into code, after obtaining a request, user-space can assign controls and one
+OUTPUT buffer to it:
+
+.. code-block:: c
+
+	struct v4l2_buffer buf;
+	struct v4l2_ext_controls ctrls;
+	int req_fd;
+	...
+	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
+		return errno;
+	...
+	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
+	ctrls.request_fd = req_fd;
+	if (ioctl(codec_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
+		return errno;
+	...
+	buf.type = V4L2_BUF_TYPE_VIDEO_OUTPUT;
+	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
+	buf.request_fd = req_fd;
+	if (ioctl(codec_fd, VIDIOC_QBUF, &buf))
+		return errno;
+
+Note that it is not allowed to use the Request API for CAPTURE buffers
+since there are no per-frame settings to report there.
+
+Once the request is fully prepared, it can be queued to the driver:
+
+.. code-block:: c
+
+	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
+		return errno;
+
+User-space can then either wait for the request to complete by calling poll() on
+its file descriptor, or start dequeuing CAPTURE buffers. Most likely, it will
+want to get CAPTURE buffers as soon as possible and this can be done using a
+regular :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`:
+
+.. code-block:: c
+
+	struct v4l2_buffer buf;
+
+	memset(&buf, 0, sizeof(buf));
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	if (ioctl(codec_fd, VIDIOC_DQBUF, &buf))
+		return errno;
+
+Note that this example assumes for simplicity that for every OUTPUT buffer
+there will be one CAPTURE buffer, but this does not have to be the case.
+
+We can then, after ensuring that the request is completed via polling the
+request file descriptor, query control values at the time of its completion via
+a call to :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.
+This is particularly useful for volatile controls for which we want to
+query values as soon as the capture buffer is produced.
+
+.. code-block:: c
+
+	struct pollfd pfd = { .events = POLLPRI, .fd = req_fd };
+	poll(&pfd, 1, -1);
+	...
+	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
+	ctrls.request_fd = req_fd;
+	if (ioctl(codec_fd, VIDIOC_G_EXT_CTRLS, &ctrls))
+		return errno;
+
+Once we don't need the request anymore, we can either recycle it for reuse with
+:ref:`MEDIA_REQUEST_IOC_REINIT`...
+
+.. code-block:: c
+
+	if (ioctl(req_fd, MEDIA_REQUEST_IOC_REINIT))
+		return errno;
+
+... or close its file descriptor to completely dispose of it.
+
+.. code-block:: c
+
+	close(req_fd);
+
+Example for a Simple Capture Device
+-----------------------------------
+
+With a simple capture device, requests can be used to specify controls to apply
+for a given CAPTURE buffer.
+
+.. code-block:: c
+
+	struct v4l2_buffer buf;
+	struct v4l2_ext_controls ctrls;
+	int req_fd;
+	...
+	if (ioctl(media_fd, MEDIA_IOC_REQUEST_ALLOC, &req_fd))
+		return errno;
+	...
+	ctrls.which = V4L2_CTRL_WHICH_REQUEST_VAL;
+	ctrls.request_fd = req_fd;
+	if (ioctl(camera_fd, VIDIOC_S_EXT_CTRLS, &ctrls))
+		return errno;
+	...
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	buf.flags |= V4L2_BUF_FLAG_REQUEST_FD;
+	buf.request_fd = req_fd;
+	if (ioctl(camera_fd, VIDIOC_QBUF, &buf))
+		return errno;
+
+Once the request is fully prepared, it can be queued to the driver:
+
+.. code-block:: c
+
+	if (ioctl(req_fd, MEDIA_REQUEST_IOC_QUEUE))
+		return errno;
+
+User-space can then dequeue buffers, wait for the request completion, query
+controls and recycle the request as in the M2M example above.

+
+    #include <sys/ioctl.h>
+
+
+.. c:function:: int ioctl( int fd, int cmd, void *argp )
+    :name: req-ioctl
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`MEDIA_IOC_REQUEST_ALLOC`.
+
+``cmd``
+    The request ioctl command code as defined in the media.h header file, for

+
+``argp``
+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+The :ref:`ioctl() <request-func-ioctl>` function manipulates request
+parameters. The argument ``fd`` must be an open file descriptor.
+
+The ioctl ``cmd`` code specifies the request function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying request ioctl commands and
+their parameters are located in the media.h header file. All request ioctl
+commands, their respective function and parameters are specified in
+:ref:`media-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Command-specific error codes are listed in the individual command
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+request-poll - Wait for some event on a file descriptor
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <sys/poll.h>
+
+
+.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )

+
+Arguments
+=========
+
+``ufds``

+   Number of file descriptor events at the \*ufds array
+
+``timeout``
+   Timeout to wait for events
+
+
+Description
+===========
+
+With the :c:func:`poll() <request-func-poll>` function applications can wait
+for a request to complete.
+
+On success :c:func:`poll() <request-func-poll>` returns the number of file
+descriptors that have been selected (that is, file descriptors for which the
+``revents`` field of the respective struct :c:type:`pollfd`
+is non-zero). Request file descriptor set the ``POLLPRI`` flag in ``revents``
+when the request was completed.  When the function times out it returns
+a value of zero, on failure it returns -1 and the ``errno`` variable is
+set appropriately.
+
+Attempting to poll for a request that is not yet queued will
+set the ``POLLERR`` flag in ``revents``.
+
+
+Return Value
+============
+
+On success, :c:func:`poll() <request-func-poll>` returns the number of
+structures which have non-zero ``revents`` fields, or zero if the call
+timed out. On error -1 is returned, and the ``errno`` variable is set
+appropriately:
+
+``EBADF``
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+``EFAULT``
+    ``ufds`` references an inaccessible memory area.
+
+``EINTR``
+    The call was interrupted by a signal.
+
+``EINVAL``
+    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
+    ``getrlimit()`` to obtain this value.

+Introduction
+************
+
+LIRC stands for Linux Infrared Remote Control. The LIRC device interface is
+a bi-directional interface for transporting raw IR and decoded scancodes
+data between userspace and kernelspace. Fundamentally, it is just a chardev
+(/dev/lircX, for X = 0, 1, 2, ...), with a number of standard struct
+file_operations defined on it. With respect to transporting raw IR and
+decoded scancodes to and fro, the essential fops are read, write and ioctl.
+
+It is also possible to attach a BPF program to a LIRC device for decoding
+raw IR into scancodes.
+
+Example dmesg output upon a driver registering w/LIRC:
+
+.. code-block:: none
+
+    $ dmesg |grep lirc_dev
+    rc rc0: lirc_dev: driver mceusb registered at minor = 0, raw IR receiver, raw IR transmitter
+
+What you should see for a chardev:
+
+.. code-block:: none
+
+    $ ls -l /dev/lirc*
+    crw-rw---- 1 root root 248, 0 Jul 2 22:20 /dev/lirc0
+
+Note that the package `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_
+contains tools for working with LIRC devices:
+
+ - ir-ctl: can receive raw IR and transmit IR, as well as query LIRC
+   device features.
+
+ - ir-keytable: can load keymaps; allows you to set IR kernel protocols; load
+   BPF IR decoders and test IR decoding. Some BPF IR decoders are also
+   provided.
+
+.. _lirc_modes:
+
+**********
+LIRC modes
+**********
+
+LIRC supports some modes of receiving and sending IR codes, as shown
+on the following table.
+
+.. _lirc-mode-scancode:
+.. _lirc-scancode-flag-toggle:
+.. _lirc-scancode-flag-repeat:
+
+``LIRC_MODE_SCANCODE``
+
+    This mode is for both sending and receiving IR.
+
+    For transmitting (aka sending), create a ``struct lirc_scancode`` with
+    the desired scancode set in the ``scancode`` member, :c:type:`rc_proto`
+    set to the :ref:`IR protocol <Remote_controllers_Protocols>`, and all other
+    members set to 0. Write this struct to the lirc device.
+
+    For receiving, you read ``struct lirc_scancode`` from the LIRC device.
+    The ``scancode`` field is set to the received scancode and the
+    :ref:`IR protocol <Remote_controllers_Protocols>` is set in
+    :c:type:`rc_proto`. If the scancode maps to a valid key code, this is set
+    in the ``keycode`` field, else it is set to ``KEY_RESERVED``.
+
+    The ``flags`` can have ``LIRC_SCANCODE_FLAG_TOGGLE`` set if the toggle
+    bit is set in protocols that support it (e.g. rc-5 and rc-6), or
+    ``LIRC_SCANCODE_FLAG_REPEAT`` for when a repeat is received for protocols
+    that support it (e.g. nec).
+
+    In the Sanyo and NEC protocol, if you hold a button on remote, rather than
+    repeating the entire scancode, the remote sends a shorter message with
+    no scancode, which just means button is held, a "repeat". When this is
+    received, the ``LIRC_SCANCODE_FLAG_REPEAT`` is set and the scancode and
+    keycode is repeated.
+
+    With nec, there is no way to distinguish "button hold" from "repeatedly
+    pressing the same button". The rc-5 and rc-6 protocols have a toggle bit.
+    When a button is released and pressed again, the toggle bit is inverted.
+    If the toggle bit is set, the ``LIRC_SCANCODE_FLAG_TOGGLE`` is set.
+
+    The ``timestamp`` field is filled with the time nanoseconds
+    (in ``CLOCK_MONOTONIC``) when the scancode was decoded.
+
+.. _lirc-mode-mode2:
+
+``LIRC_MODE_MODE2``
+
+    The driver returns a sequence of pulse and space codes to userspace,
+    as a series of u32 values.
+
+    This mode is used only for IR receive.
+
+    The upper 8 bits determine the packet type, and the lower 24 bits
+    the payload. Use ``LIRC_VALUE()`` macro to get the payload, and
+    the macro ``LIRC_MODE2()`` will give you the type, which
+    is one of:
+
+    ``LIRC_MODE2_PULSE``
+
+        Signifies the presence of IR in microseconds.
+
+    ``LIRC_MODE2_SPACE``
+
+        Signifies absence of IR in microseconds.
+
+    ``LIRC_MODE2_FREQUENCY``
+
+        If measurement of the carrier frequency was enabled with
+        :ref:`lirc_set_measure_carrier_mode` then this packet gives you
+        the carrier frequency in Hertz.
+
+    ``LIRC_MODE2_TIMEOUT``
+
+        If timeout reports are enabled with
+        :ref:`lirc_set_rec_timeout_reports`, when the timeout set with
+        :ref:`lirc_set_rec_timeout` expires due to no IR being detected,
+        this packet will be sent, with the number of microseconds with
+        no IR.
+
+.. _lirc-mode-pulse:
+
+``LIRC_MODE_PULSE``
+
+    In pulse mode, a sequence of pulse/space integer values are written to the
+    lirc device using :ref:`lirc-write`.
+
+    The values are alternating pulse and space lengths, in microseconds. The
+    first and last entry must be a pulse, so there must be an odd number
+    of entries.
+
+    This mode is used only for IR send.
+
+********************
+BPF based IR decoder
+********************
+
+The kernel has support for decoding the most common
+:ref:`IR protocols <Remote_controllers_Protocols>`, but there
+are many protocols which are not supported. To support these, it is possible
+to load an BPF program which does the decoding. This can only be done on
+LIRC devices which support reading raw IR.
+
+First, using the `bpf(2)`_ syscall with the ``BPF_LOAD_PROG`` argument,
+program must be loaded of type ``BPF_PROG_TYPE_LIRC_MODE2``. Once attached
+to the LIRC device, this program will be called for each pulse, space or
+timeout event on the LIRC device. The context for the BPF program is a
+pointer to a unsigned int, which is a :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>`
+value. When the program has decoded the scancode, it can be submitted using
+the BPF functions ``bpf_rc_keydown()`` or ``bpf_rc_repeat()``. Mouse or pointer
+movements can be reported using ``bpf_rc_pointer_rel()``.
+
+Once you have the file descriptor for the ``BPF_PROG_TYPE_LIRC_MODE2`` BPF
+program, it can be attached to the LIRC device using the `bpf(2)`_ syscall.
+The target must be the file descriptor for the LIRC device, and the
+attach type must be ``BPF_LIRC_MODE2``. No more than 64 BPF programs can be
+attached to a single LIRC device at a time.
+
+.. _bpf(2): http://man7.org/linux/man-pages/man2/bpf.2.html

+``fd``
+    File descriptor returned by open().
+
+``timeout``
+    Timeout, in microseconds.
+
+
+Description
+===========
+
+Some devices have internal timers that can be used to detect when
+there's no IR activity for a long time. This can help lircd in
+detecting that a IR signal is finished and can speed up the decoding
+process. Returns an integer value with the minimum/maximum timeout
+that can be set.
+
+.. note::
+
+   Some devices have a fixed timeout, in that case
+   both ioctls will return the same value even though the timeout
+   cannot be changed via :ref:`LIRC_SET_REC_TIMEOUT`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+
+
+.. c:function:: ssize_t read( int fd, void *buf, size_t count )
+    :name: lirc-read
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by ``open()``.
+
+``buf``
+   Buffer to be filled
+
+``count``
+   Max number of bytes to read
+
+Description
+===========
+
+:ref:`read() <lirc-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``.  If ``count`` is zero,
+:ref:`read() <lirc-read>` returns zero and has no other results. If ``count``
+is greater than ``SSIZE_MAX``, the result is unspecified.
+
+The exact format of the data depends on what :ref:`lirc_modes` a driver
+uses. Use :ref:`lirc_get_features` to get the supported mode, and use
+:ref:`lirc_set_rec_mode` set the current active mode.
+
+The mode :ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>` is for raw IR,
+in which packets containing an unsigned int value describing an IR signal are
+read from the chardev.
+
+Alternatively, :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` can be available,
+in this mode scancodes which are either decoded by software decoders, or
+by hardware decoders. The :c:type:`rc_proto` member is set to the
+:ref:`IR protocol <Remote_controllers_Protocols>`
+used for transmission, and ``scancode`` to the decoded scancode,
+and the ``keycode`` set to the keycode or ``KEY_RESERVED``.
+
+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame.  On error, -1 is returned, and the ``errno``
+variable is set appropriately.

+encoded by the least significant bit and so on.
+
+When an invalid bit mask is given, i.e. a bit is set, even though the device
+does not have so many transitters, then this ioctl returns the number of
+available transitters and does nothing otherwise.

+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+LIRC_SET_WIDEBAND_RECEIVER - enable wide band receiver.
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, LIRC_SET_WIDEBAND_RECEIVER, __u32 *enable )
+    :name: LIRC_SET_WIDEBAND_RECEIVER
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by open().
+
+``enable``
+    enable = 1 means enable wideband receiver, enable = 0 means disable
+    wideband receiver.
+
+
+Description
+===========
+
+Some receivers are equipped with special wide band receiver which is
+intended to be used to learn output of existing remote. This ioctl
+allows enabling or disabling it.
+
+This might be useful of receivers that have otherwise narrow band receiver
+that prevents them to be used with some remotes. Wide band receiver might
+also be more precise. On the other hand its disadvantage it usually
+reduced range of reception.
+
+.. note::
+
+    Wide band receiver might be implictly enabled if you enable
+    carrier reports. In that case it will be disabled as soon as you disable
+    carrier reports. Trying to disable wide band receiver while carrier
+    reports are active will do nothing.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+    #include <unistd.h>
+
+
+.. c:function:: ssize_t write( int fd, void *buf, size_t count )

+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by ``open()``.
+
+``buf``
+    Buffer with data to be written
+
+``count``
+    Number of bytes at the buffer
+
+Description
+===========
+
+:ref:`write() <lirc-write>` writes up to ``count`` bytes to the device
+referenced by the file descriptor ``fd`` from the buffer starting at
+``buf``.
+
+The exact format of the data depends on what mode a driver is in, use
+:ref:`lirc_get_features` to get the supported modes and use
+:ref:`lirc_set_send_mode` set the mode.
+
+When in :ref:`LIRC_MODE_PULSE <lirc-mode-PULSE>` mode, the data written to
+the chardev is a pulse/space sequence of integer values. Pulses and spaces
+are only marked implicitly by their position. The data must start and end
+with a pulse, therefore, the data must always include an uneven number of
+samples. The write function blocks until the data has been transmitted
+by the hardware. If more data is provided than the hardware can send, the
+driver returns ``EINVAL``.
+
+When in :ref:`LIRC_MODE_SCANCODE <lirc-mode-scancode>` mode, one
+``struct lirc_scancode`` must be written to the chardev at a time, else
+``EINVAL`` is returned. Set the desired scancode in the ``scancode`` member,
+and the :ref:`IR protocol <Remote_controllers_Protocols>` in the
+:c:type:`rc_proto`: member. All other members must be
+set to 0, else ``EINVAL`` is returned. If there is no protocol encoder
+for the protocol or the scancode is not valid for the specified protocol,
+``EINVAL`` is returned. The write function blocks until the scancode
+is transmitted by the hardware.
+
+
+Return Value
+============
+
+On success, the number of bytes written is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame.  On error, -1 is returned, and the ``errno``
+variable is set appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+Introduction
+************
+
+Currently, most analog and digital devices have a Infrared input for
+remote controllers. Each manufacturer has their own type of control. It
+is not rare for the same manufacturer to ship different types of
+controls, depending on the device.
+
+A Remote Controller interface is mapped as a normal evdev/input
+interface, just like a keyboard or a mouse. So, it uses all ioctls
+already defined for any other input devices.
+
+However, remove controllers are more flexible than a normal input
+device, as the IR receiver (and/or transmitter) can be used in
+conjunction with a wide variety of different IR remotes.
+
+In order to allow flexibility, the Remote Controller subsystem allows
+controlling the RC-specific attributes via
+:ref:`the sysfs class nodes <remote_controllers_sysfs_nodes>`.

+Remote Controller's sysfs nodes
+*******************************
+
+As defined at ``Documentation/ABI/testing/sysfs-class-rc``, those are
+the sysfs nodes that control the Remote Controllers:
+
+
+.. _sys_class_rc:
+
+/sys/class/rc/
+==============
+
+The ``/sys/class/rc/`` class sub-directory belongs to the Remote
+Controller core and provides a sysfs interface for configuring infrared
+remote controller receivers.
+
+
+.. _sys_class_rc_rcN:
+
+/sys/class/rc/rcN/
+==================
+
+A ``/sys/class/rc/rcN`` directory is created for each remote control
+receiver device where N is the number of the receiver.
+
+
+.. _sys_class_rc_rcN_protocols:
+
+/sys/class/rc/rcN/protocols
+===========================
+
+Reading this file returns a list of available protocols, something like::
+
+	rc5 [rc6] nec jvc [sony]
+
+Enabled protocols are shown in [] brackets.
+
+Writing "+proto" will add a protocol to the list of enabled protocols.
+
+Writing "-proto" will remove a protocol from the list of enabled
+protocols.
+
+Writing "proto" will enable only "proto".
+
+Writing "none" will disable all protocols.
+
+Write fails with ``EINVAL`` if an invalid protocol combination or unknown
+protocol name is used.
+
+
+.. _sys_class_rc_rcN_filter:
+
+/sys/class/rc/rcN/filter
+========================
+
+Sets the scancode filter expected value.
+
+Use in combination with ``/sys/class/rc/rcN/filter_mask`` to set the
+expected value of the bits set in the filter mask. If the hardware
+supports it then scancodes which do not match the filter will be
+ignored. Otherwise the write will fail with an error.
+
+This value may be reset to 0 if the current protocol is altered.
+
+
+.. _sys_class_rc_rcN_filter_mask:
+
+/sys/class/rc/rcN/filter_mask
+=============================
+
+Sets the scancode filter mask of bits to compare. Use in combination
+with ``/sys/class/rc/rcN/filter`` to set the bits of the scancode which
+should be compared against the expected value. A value of 0 disables the
+filter to allow all valid scancodes to be processed.
+
+If the hardware supports it then scancodes which do not match the filter
+will be ignored. Otherwise the write will fail with an error.
+
+This value may be reset to 0 if the current protocol is altered.
+
+
+.. _sys_class_rc_rcN_wakeup_protocols:
+
+/sys/class/rc/rcN/wakeup_protocols
+==================================
+
+Reading this file returns a list of available protocols to use for the
+wakeup filter, something like::
+
+	rc-5 nec nec-x rc-6-0 rc-6-6a-24 [rc-6-6a-32] rc-6-mce
+
+Note that protocol variants are listed, so ``nec``, ``sony``, ``rc-5``, ``rc-6``
+have their different bit length encodings listed if available.
+
+Note that all protocol variants are listed.
+
+The enabled wakeup protocol is shown in [] brackets.
+
+Only one protocol can be selected at a time.
+
+Writing "proto" will use "proto" for wakeup events.
+
+Writing "none" will disable wakeup.
+
+Write fails with ``EINVAL`` if an invalid protocol combination or unknown
+protocol name is used, or if wakeup is not supported by the hardware.
+
+
+.. _sys_class_rc_rcN_wakeup_filter:
+
+/sys/class/rc/rcN/wakeup_filter
+===============================
+
+Sets the scancode wakeup filter expected value. Use in combination with
+``/sys/class/rc/rcN/wakeup_filter_mask`` to set the expected value of
+the bits set in the wakeup filter mask to trigger a system wake event.
+
+If the hardware supports it and wakeup_filter_mask is not 0 then
+scancodes which match the filter will wake the system from e.g. suspend
+to RAM or power off. Otherwise the write will fail with an error.
+
+This value may be reset to 0 if the wakeup protocol is altered.
+
+
+.. _sys_class_rc_rcN_wakeup_filter_mask:
+
+/sys/class/rc/rcN/wakeup_filter_mask
+====================================
+
+Sets the scancode wakeup filter mask of bits to compare. Use in

+
+Unfortunately, for several years, there was no effort to create uniform
+IR keycodes for different devices. This caused the same IR keyname to be
+mapped completely differently on different IR devices. This resulted
+that the same IR keyname to be mapped completely different on different
+IR's. Due to that, V4L2 API now specifies a standard for mapping Media
+keys on IR.
+
+This standard should be used by both V4L/DVB drivers and userspace
+applications
+
+The modules register the remote as keyboard within the linux input
+layer. This means that the IR key strokes will look like normal keyboard
+key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event
+devices (CONFIG_INPUT_EVDEV) it is possible for applications to access
+the remote via /dev/input/event devices.

+********************
+Application Priority
+********************
+
+When multiple applications share a device it may be desirable to assign
+them different priorities. Contrary to the traditional "rm -rf /" school
+of thought, a video recording application could for example block other
+applications from changing video controls or switching the current TV
+channel. Another objective is to permit low priority applications
+working in background, which can be preempted by user controlled
+applications and automatically regain control of the device at a later
+time.
+
+Since these features cannot be implemented entirely in user space V4L2
+defines the :ref:`VIDIOC_G_PRIORITY <VIDIOC_G_PRIORITY>` and
+:ref:`VIDIOC_S_PRIORITY <VIDIOC_G_PRIORITY>` ioctls to request and
+query the access priority associate with a file descriptor. Opening a
+device assigns a medium priority, compatible with earlier versions of
+V4L2 and drivers not supporting these ioctls. Applications requiring a
+different priority will usually call :ref:`VIDIOC_S_PRIORITY
+<VIDIOC_G_PRIORITY>` after verifying the device with the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+Ioctls changing driver properties, such as
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>`, return an ``EBUSY`` error code
+after another application obtained higher priority.

+************************
+Audio Inputs and Outputs
+************************
+
+Audio inputs and outputs are physical connectors of a device. Video
+capture devices have inputs, output devices have outputs, zero or more
+each. Radio devices have no audio inputs or outputs. They have exactly
+one tuner which in fact *is* an audio source, but this API associates
+tuners with video inputs or outputs only, and radio devices have none of
+these. [#f1]_ A connector on a TV card to loop back the received audio
+signal to a sound card is not considered an audio output.
+
+Audio and video inputs and outputs are associated. Selecting a video
+source also selects an audio source. This is most evident when the video
+and audio source is a tuner. Further audio connectors can combine with
+more than one video input or output. Assumed two composite video inputs
+and two audio inputs exist, there may be up to four valid combinations.
+The relation of video and audio connectors is defined in the
+``audioset`` field of the respective struct
+:c:type:`v4l2_input` or struct
+:c:type:`v4l2_output`, where each bit represents the index
+number, starting at zero, of one audio input or output.
+
+To learn about the number and attributes of the available inputs and
+outputs applications can enumerate them with the
+:ref:`VIDIOC_ENUMAUDIO` and
+:ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` ioctl, respectively.
+The struct :c:type:`v4l2_audio` returned by the
+:ref:`VIDIOC_ENUMAUDIO` ioctl also contains signal
+status information applicable when the current audio input is queried.
+
+The :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
+:ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` ioctls report the current
+audio input and output, respectively.
+
+.. note::
+
+   Note that, unlike :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+   :ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` these ioctls return a
+   structure as :ref:`VIDIOC_ENUMAUDIO` and
+   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` do, not just an index.
+
+To select an audio input and change its properties applications call the
+:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` ioctl. To select an audio
+output (which presently has no changeable properties) applications call
+the :ref:`VIDIOC_S_AUDOUT <VIDIOC_G_AUDOUT>` ioctl.
+
+Drivers must implement all audio input ioctls when the device has
+multiple selectable audio inputs, all audio output ioctls when the
+device has multiple selectable audio outputs. When the device has any
+audio inputs or outputs the driver must set the ``V4L2_CAP_AUDIO`` flag
+in the struct :c:type:`v4l2_capability` returned by
+the :ref:`VIDIOC_QUERYCAP` ioctl.
+
+
+Example: Information about the current audio input
+==================================================
+
+.. code-block:: c
+
+    struct v4l2_audio audio;
+
+    memset(&audio, 0, sizeof(audio));
+
+    if (-1 == ioctl(fd, VIDIOC_G_AUDIO, &audio)) {
+	perror("VIDIOC_G_AUDIO");
+	exit(EXIT_FAILURE);
+    }
+
+    printf("Current input: %s\\n", audio.name);
+
+
+Example: Switching to the first audio input
+===========================================
+
+.. code-block:: c
+
+    struct v4l2_audio audio;
+
+    memset(&audio, 0, sizeof(audio)); /* clear audio.mode, audio.reserved */
+
+    audio.index = 0;
+
+    if (-1 == ioctl(fd, VIDIOC_S_AUDIO, &audio)) {
+	perror("VIDIOC_S_AUDIO");
+	exit(EXIT_FAILURE);
+    }
+
+.. [#f1]
+   Actually struct :c:type:`v4l2_audio` ought to have a
+   ``tuner`` field like struct :c:type:`v4l2_input`, not
+   only making the API more consistent but also permitting radio devices
+   with multiple tuners.

+*******
+Buffers
+*******
+
+A buffer contains data exchanged by application and driver using one of
+the Streaming I/O methods. In the multi-planar API, the data is held in
+planes, while the buffer structure acts as a container for the planes.
+Only pointers to buffers (planes) are exchanged, the data itself is not
+copied. These pointers, together with meta-information like timestamps
+or field parity, are stored in a struct :c:type:`v4l2_buffer`,
+argument to the :ref:`VIDIOC_QUERYBUF`,
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` and
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. In the multi-planar API,
+some plane-specific members of struct :c:type:`v4l2_buffer`,
+such as pointers and sizes for each plane, are stored in struct
+struct :c:type:`v4l2_plane` instead. In that case, struct
+struct :c:type:`v4l2_buffer` contains an array of plane structures.
+
+Dequeued video buffers come with timestamps. The driver decides at which
+part of the frame and with which clock the timestamp is taken. Please
+see flags in the masks ``V4L2_BUF_FLAG_TIMESTAMP_MASK`` and
+``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` in :ref:`buffer-flags`. These flags
+are always valid and constant across all buffers during the whole video
+stream. Changes in these flags may take place as a side effect of
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` or
+:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` however. The
+``V4L2_BUF_FLAG_TIMESTAMP_COPY`` timestamp type which is used by e.g. on
+mem-to-mem devices is an exception to the rule: the timestamp source
+flags are copied from the OUTPUT video buffer to the CAPTURE video
+buffer.
+
+
+Interactions between formats, controls and buffers
+==================================================
+
+V4L2 exposes parameters that influence the buffer size, or the way data is
+laid out in the buffer. Those parameters are exposed through both formats and
+controls. One example of such a control is the ``V4L2_CID_ROTATE`` control
+that modifies the direction in which pixels are stored in the buffer, as well
+as the buffer size when the selected format includes padding at the end of
+lines.
+
+The set of information needed to interpret the content of a buffer (e.g. the
+pixel format, the line stride, the tiling orientation or the rotation) is
+collectively referred to in the rest of this section as the buffer layout.
+
+Controls that can modify the buffer layout shall set the
+``V4L2_CTRL_FLAG_MODIFY_LAYOUT`` flag.
+
+Modifying formats or controls that influence the buffer size or layout require
+the stream to be stopped. Any attempt at such a modification while the stream
+is active shall cause the ioctl setting the format or the control to return
+the ``EBUSY`` error code. In that case drivers shall also set the
+``V4L2_CTRL_FLAG_GRABBED`` flag when calling
+:c:func:`VIDIOC_QUERYCTRL` or :c:func:`VIDIOC_QUERY_EXT_CTRL` for such a
+control while the stream is active.
+
+.. note::
+
+   The :c:func:`VIDIOC_S_SELECTION` ioctl can, depending on the hardware (for
+   instance if the device doesn't include a scaler), modify the format in
+   addition to the selection rectangle. Similarly, the
+   :c:func:`VIDIOC_S_INPUT`, :c:func:`VIDIOC_S_OUTPUT`, :c:func:`VIDIOC_S_STD`
+   and :c:func:`VIDIOC_S_DV_TIMINGS` ioctls can also modify the format and
+   selection rectangles. When those ioctls result in a buffer size or layout
+   change, drivers shall handle that condition as they would handle it in the
+   :c:func:`VIDIOC_S_FMT` ioctl in all cases described in this section.
+
+Controls that only influence the buffer layout can be modified at any time
+when the stream is stopped. As they don't influence the buffer size, no
+special handling is needed to synchronize those controls with buffer
+allocation and the ``V4L2_CTRL_FLAG_GRABBED`` flag is cleared once the
+stream is stopped.
+
+Formats and controls that influence the buffer size interact with buffer
+allocation. The simplest way to handle this is for drivers to always require
+buffers to be reallocated in order to change those formats or controls. In
+that case, to perform such changes, userspace applications shall first stop
+the video stream with the :c:func:`VIDIOC_STREAMOFF` ioctl if it is running
+and free all buffers with the :c:func:`VIDIOC_REQBUFS` ioctl if they are
+allocated. After freeing all buffers the ``V4L2_CTRL_FLAG_GRABBED`` flag
+for controls is cleared. The format or controls can then be modified, and
+buffers shall then be reallocated and the stream restarted. A typical ioctl
+sequence is
+
+ #. VIDIOC_STREAMOFF
+ #. VIDIOC_REQBUFS(0)
+ #. VIDIOC_S_EXT_CTRLS
+ #. VIDIOC_S_FMT
+ #. VIDIOC_REQBUFS(n)
+ #. VIDIOC_QBUF
+ #. VIDIOC_STREAMON
+
+The second :c:func:`VIDIOC_REQBUFS` call will take the new format and control
+value into account to compute the buffer size to allocate. Applications can
+also retrieve the size by calling the :c:func:`VIDIOC_G_FMT` ioctl if needed.
+
+.. note::
+
+   The API doesn't mandate the above order for control (3.) and format (4.)
+   changes. Format and controls can be set in a different order, or even
+   interleaved, depending on the device and use case. For instance some
+   controls might behave differently for different pixel formats, in which
+   case the format might need to be set first.
+
+When reallocation is required, any attempt to modify format or controls that
+influences the buffer size while buffers are allocated shall cause the format
+or control set ioctl to return the ``EBUSY`` error. Any attempt to queue a
+buffer too small for the current format or controls shall cause the
+:c:func:`VIDIOC_QBUF` ioctl to return a ``EINVAL`` error.
+
+Buffer reallocation is an expensive operation. To avoid that cost, drivers can
+(and are encouraged to) allow format or controls that influence the buffer
+size to be changed with buffers allocated. In that case, a typical ioctl
+sequence to modify format and controls is
+
+ #. VIDIOC_STREAMOFF
+ #. VIDIOC_S_EXT_CTRLS
+ #. VIDIOC_S_FMT
+ #. VIDIOC_QBUF
+ #. VIDIOC_STREAMON
+
+For this sequence to operate correctly, queued buffers need to be large enough
+for the new format or controls. Drivers shall return a ``ENOSPC`` error in
+response to format change (:c:func:`VIDIOC_S_FMT`) or control changes
+(:c:func:`VIDIOC_S_CTRL` or :c:func:`VIDIOC_S_EXT_CTRLS`) if buffers too small
+for the new format are currently queued. As a simplification, drivers are
+allowed to return a ``EBUSY`` error from these ioctls if any buffer is
+currently queued, without checking the queued buffers sizes.
+
+Additionally, drivers shall return a ``EINVAL`` error from the
+:c:func:`VIDIOC_QBUF` ioctl if the buffer being queued is too small for the
+current format or controls. Together, these requirements ensure that queued
+buffers will always be large enough for the configured format and controls.
+
+Userspace applications can query the buffer size required for a given format
+and controls by first setting the desired control values and then trying the
+desired format. The :c:func:`VIDIOC_TRY_FMT` ioctl will return the required
+buffer size.
+
+ #. VIDIOC_S_EXT_CTRLS(x)
+ #. VIDIOC_TRY_FMT()
+ #. VIDIOC_S_EXT_CTRLS(y)
+ #. VIDIOC_TRY_FMT()
+
+The :c:func:`VIDIOC_CREATE_BUFS` ioctl can then be used to allocate buffers
+based on the queried sizes (for instance by allocating a set of buffers large
+enough for all the desired formats and controls, or by allocating separate set
+of appropriately sized buffers for each use case).

+	driver. This field can range from zero to the number of buffers
+	allocated with the :ref:`VIDIOC_REQBUFS` ioctl
+	(struct :c:type:`v4l2_requestbuffers`
+	``count``), plus any buffers allocated with
+	:ref:`VIDIOC_CREATE_BUFS` minus one.
+    * - __u32
+      - ``type``
+      - Type of the buffer, same as struct
+	:c:type:`v4l2_format` ``type`` or struct
+	:c:type:`v4l2_requestbuffers` ``type``, set
+	by the application. See :c:type:`v4l2_buf_type`
+    * - __u32
+      - ``bytesused``
+      - The number of bytes occupied by the data in the buffer. It depends
+	on the negotiated data format and may change with each buffer for
+	compressed variable size data like JPEG images. Drivers must set
+	this field when ``type`` refers to a capture stream, applications
+	when it refers to an output stream. If the application sets this
+	to 0 for an output stream, then ``bytesused`` will be set to the
+	size of the buffer (see the ``length`` field of this struct) by
+	the driver. For multiplanar formats this field is ignored and the
+	``planes`` pointer is used instead.
+    * - __u32
+      - ``flags``
+      - Flags set by the application or driver, see :ref:`buffer-flags`.
+    * - __u32
+      - ``field``
+      - Indicates the field order of the image in the buffer, see
+	:c:type:`v4l2_field`. This field is not used when the buffer
+	contains VBI data. Drivers must set it when ``type`` refers to a
+	capture stream, applications when it refers to an output stream.
+    * - struct timeval
+      - ``timestamp``
+      - For capture streams this is time when the first data byte was
+	captured, as returned by the :c:func:`clock_gettime()` function
+	for the relevant clock id; see ``V4L2_BUF_FLAG_TIMESTAMP_*`` in
+	:ref:`buffer-flags`. For output streams the driver stores the
+	time at which the last data byte was actually sent out in the
+	``timestamp`` field. This permits applications to monitor the
+	drift between the video and system clock. For output streams that
+	use ``V4L2_BUF_FLAG_TIMESTAMP_COPY`` the application has to fill
+	in the timestamp which will be copied by the driver to the capture
+	stream.
+    * - struct :c:type:`v4l2_timecode`
+      - ``timecode``
+      - When the ``V4L2_BUF_FLAG_TIMECODE`` flag is set in ``flags``, this
+	structure contains a frame timecode. In
+	:c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
+	bottom field contain the same timecode. Timecodes are intended to
+	help video editing and are typically recorded on video tapes, but
+	also embedded in compressed formats like MPEG. This field is
+	independent of the ``timestamp`` and ``sequence`` fields.
+    * - __u32
+      - ``sequence``
+      - Set by the driver, counting the frames (not fields!) in sequence.
+	This field is set for both input and output devices.
+    * - :cspan:`2`
+
+	In :c:type:`V4L2_FIELD_ALTERNATE <v4l2_field>` mode the top and
+	bottom field have the same sequence number. The count starts at
+	zero and includes dropped or repeated frames. A dropped frame was
+	received by an input device but could not be stored due to lack of
+	free buffer space. A repeated frame was displayed again by an
+	output device because the application did not pass new data in
+	time.
+
+	.. note::
+
+	   This may count the frames received e.g. over USB, without
+	   taking into account the frames dropped by the remote hardware due
+	   to limited compression throughput or bus bandwidth. These devices
+	   identify by not enumerating any video standards, see
+	   :ref:`standard`.
+
+    * - __u32
+      - ``memory``
+      - This field must be set by applications and/or drivers in
+	accordance with the selected I/O method. See :c:type:`v4l2_memory`
+    * - union {
+      - ``m``
+    * - __u32
+      - ``offset``
+      - For the single-planar API and when ``memory`` is
+	``V4L2_MEMORY_MMAP`` this is the offset of the buffer from the
+	start of the device memory. The value is returned by the driver
+	and apart of serving as parameter to the
+	:ref:`mmap() <func-mmap>` function not useful for applications.
+	See :ref:`mmap` for details
+    * - unsigned long
+      - ``userptr``
+      - For the single-planar API and when ``memory`` is
+	``V4L2_MEMORY_USERPTR`` this is a pointer to the buffer (casted to
+	unsigned long type) in virtual memory, set by the application. See
+	:ref:`userp` for details.
+    * - struct v4l2_plane
+      - ``*planes``
+      - When using the multi-planar API, contains a userspace pointer to
+	an array of struct :c:type:`v4l2_plane`. The size of
+	the array should be put in the ``length`` field of this
+	struct :c:type:`v4l2_buffer` structure.
+    * - int
+      - ``fd``
+      - For the single-plane API and when ``memory`` is
+	``V4L2_MEMORY_DMABUF`` this is the file descriptor associated with
+	a DMABUF buffer.
+    * - }
+      -
+    * - __u32
+      - ``length``
+      - Size of the buffer (not the payload) in bytes for the
+	single-planar API. This is set by the driver based on the calls to
+	:ref:`VIDIOC_REQBUFS` and/or
+	:ref:`VIDIOC_CREATE_BUFS`. For the
+	multi-planar API the application sets this to the number of
+	elements in the ``planes`` array. The driver will fill in the
+	actual number of valid elements in that array.
+    * - __u32
+      - ``reserved2``
+      - A place holder for future extensions. Drivers and applications
+	must set this to 0.
+    * - __u32
+      - ``request_fd``
+      - The file descriptor of the request to queue the buffer to. If the flag
+        ``V4L2_BUF_FLAG_REQUEST_FD`` is set, then the buffer will be
+	queued to this request. If the flag is not set, then this field will
+	be ignored.
+
+	The ``V4L2_BUF_FLAG_REQUEST_FD`` flag and this field are only used by
+	:ref:`ioctl VIDIOC_QBUF <VIDIOC_QBUF>` and ignored by other ioctls that
+	take a :c:type:`v4l2_buffer` as argument.

+
+      - ``V4L2_BUF_FLAG_MAPPED``
+      - 0x00000001
+      - The buffer resides in device memory and has been mapped into the
+	application's address space, see :ref:`mmap` for details.
+	Drivers set or clear this flag when the
+	:ref:`VIDIOC_QUERYBUF`,
+	:ref:`VIDIOC_QBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Set by the
+	driver.
+    * .. _`V4L2-BUF-FLAG-QUEUED`:
+
+      - ``V4L2_BUF_FLAG_QUEUED``
+      - 0x00000002
+      - Internally drivers maintain two buffer queues, an incoming and
+	outgoing queue. When this flag is set, the buffer is currently on
+	the incoming queue. It automatically moves to the outgoing queue
+	after the buffer has been filled (capture devices) or displayed
+	(output devices). Drivers set or clear this flag when the
+	``VIDIOC_QUERYBUF`` ioctl is called. After (successful) calling
+	the ``VIDIOC_QBUF``\ ioctl it is always set and after
+	``VIDIOC_DQBUF`` always cleared.
+    * .. _`V4L2-BUF-FLAG-DONE`:
+
+      - ``V4L2_BUF_FLAG_DONE``
+      - 0x00000004
+      - When this flag is set, the buffer is currently on the outgoing
+	queue, ready to be dequeued from the driver. Drivers set or clear
+	this flag when the ``VIDIOC_QUERYBUF`` ioctl is called. After
+	calling the ``VIDIOC_QBUF`` or ``VIDIOC_DQBUF`` it is always
+	cleared. Of course a buffer cannot be on both queues at the same
+	time, the ``V4L2_BUF_FLAG_QUEUED`` and ``V4L2_BUF_FLAG_DONE`` flag
+	are mutually exclusive. They can be both cleared however, then the
+	buffer is in "dequeued" state, in the application domain so to
+	say.
+    * .. _`V4L2-BUF-FLAG-ERROR`:
+
+      - ``V4L2_BUF_FLAG_ERROR``
+      - 0x00000040
+      - When this flag is set, the buffer has been dequeued successfully,
+	although the data might have been corrupted. This is recoverable,
+	streaming may continue as normal and the buffer may be reused
+	normally. Drivers set this flag when the ``VIDIOC_DQBUF`` ioctl is
+	called.
+    * .. _`V4L2-BUF-FLAG-IN-REQUEST`:
+
+      - ``V4L2_BUF_FLAG_IN_REQUEST``
+      - 0x00000080
+      - This buffer is part of a request that hasn't been queued yet.
+    * .. _`V4L2-BUF-FLAG-KEYFRAME`:
+
+      - ``V4L2_BUF_FLAG_KEYFRAME``
+      - 0x00000008
+      - Drivers set or clear this flag when calling the ``VIDIOC_DQBUF``
+	ioctl. It may be set by video capture devices when the buffer
+	contains a compressed image which is a key frame (or field), i. e.
+	can be decompressed on its own. Also known as an I-frame.
+	Applications can set this bit when ``type`` refers to an output
+	stream.
+    * .. _`V4L2-BUF-FLAG-PFRAME`:
+
+      - ``V4L2_BUF_FLAG_PFRAME``
+      - 0x00000010
+      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags predicted frames
+	or fields which contain only differences to a previous key frame.
+	Applications can set this bit when ``type`` refers to an output
+	stream.
+    * .. _`V4L2-BUF-FLAG-BFRAME`:
+
+      - ``V4L2_BUF_FLAG_BFRAME``
+      - 0x00000020
+      - Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional
+	predicted frame or field which contains only the differences
+	between the current frame and both the preceding and following key
+	frames to specify its content. Applications can set this bit when
+	``type`` refers to an output stream.
+    * .. _`V4L2-BUF-FLAG-TIMECODE`:
+
+      - ``V4L2_BUF_FLAG_TIMECODE``
+      - 0x00000100
+      - The ``timecode`` field is valid. Drivers set or clear this flag
+	when the ``VIDIOC_DQBUF`` ioctl is called. Applications can set
+	this bit and the corresponding ``timecode`` structure when
+	``type`` refers to an output stream.
+    * .. _`V4L2-BUF-FLAG-PREPARED`:
+
+      - ``V4L2_BUF_FLAG_PREPARED``
+      - 0x00000400
+      - The buffer has been prepared for I/O and can be queued by the
+	application. Drivers set or clear this flag when the
+	:ref:`VIDIOC_QUERYBUF`,
+	:ref:`VIDIOC_PREPARE_BUF <VIDIOC_QBUF>`,
+	:ref:`VIDIOC_QBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called.
+    * .. _`V4L2-BUF-FLAG-NO-CACHE-INVALIDATE`:
+
+      - ``V4L2_BUF_FLAG_NO_CACHE_INVALIDATE``
+      - 0x00000800
+      - Caches do not have to be invalidated for this buffer. Typically
+	applications shall use this flag if the data captured in the
+	buffer is not going to be touched by the CPU, instead the buffer
+	will, probably, be passed on to a DMA-capable hardware unit for
+	further processing or output.
+    * .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
+
+      - ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
+      - 0x00001000
+      - Caches do not have to be cleaned for this buffer. Typically
+	applications shall use this flag for output buffers if the data in
+	this buffer has not been created by the CPU but by some
+	DMA-capable unit, in which case caches have not been used.
+    * .. _`V4L2-BUF-FLAG-M2M-HOLD-CAPTURE-BUF`:
+
+      - ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF``
+      - 0x00000200
+      - Only valid if ``V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF`` is
+	set. It is typically used with stateless decoders where multiple
+	output buffers each decode to a slice of the decoded frame.
+	Applications can set this flag when queueing the output buffer
+	to prevent the driver from dequeueing the capture buffer after
+	the output buffer has been decoded (i.e. the capture buffer is
+	'held'). If the timestamp of this output buffer differs from that
+	of the previous output buffer, then that indicates the start of a
+	new frame and the previously held capture buffer is dequeued.
+    * .. _`V4L2-BUF-FLAG-LAST`:
+
+      - ``V4L2_BUF_FLAG_LAST``
+      - 0x00100000
+      - Last buffer produced by the hardware. mem2mem codec drivers set
+	this flag on the capture queue for the last buffer when the
+	:ref:`VIDIOC_QUERYBUF` or
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
+	hardware limitations, the last buffer may be empty. In this case
+	the driver will set the ``bytesused`` field to 0, regardless of
+	the format. Any Any subsequent call to the
+	:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
+	but return an ``EPIPE`` error code.
+    * .. _`V4L2-BUF-FLAG-REQUEST-FD`:
+
+      - ``V4L2_BUF_FLAG_REQUEST_FD``
+      - 0x00800000
+      - The ``request_fd`` field contains a valid file descriptor.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MASK`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_MASK``
+      - 0x0000e000
+      - Mask for timestamp types below. To test the timestamp type, mask
+	out bits not belonging to timestamp type by performing a logical
+	and operation with buffer flags and timestamp mask.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-UNKNOWN`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
+      - 0x00000000
+      - Unknown timestamp type. This type is used by drivers before Linux
+	3.9 and may be either monotonic (see below) or realtime (wall
+	clock). Monotonic clock has been favoured in embedded systems
+	whereas most of the drivers use the realtime clock. Either kinds
+	of timestamps are available in user space via
+	:c:func:`clock_gettime` using clock IDs ``CLOCK_MONOTONIC``
+	and ``CLOCK_REALTIME``, respectively.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
+      - 0x00002000
+      - The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``
+	clock. To access the same clock outside V4L2, use
+	:c:func:`clock_gettime`.
+    * .. _`V4L2-BUF-FLAG-TIMESTAMP-COPY`:
+
+      - ``V4L2_BUF_FLAG_TIMESTAMP_COPY``
+      - 0x00004000
+      - The CAPTURE buffer timestamp has been taken from the corresponding
+	OUTPUT buffer. This flag applies only to mem2mem devices.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-MASK`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK``
+      - 0x00070000
+      - Mask for timestamp sources below. The timestamp source defines the
+	point of time the timestamp is taken in relation to the frame.
+	Logical 'and' operation between the ``flags`` field and
+	``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` produces the value of the
+	timestamp source. Applications must set the timestamp source when
+	``type`` refers to an output stream and
+	``V4L2_BUF_FLAG_TIMESTAMP_COPY`` is set.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-EOF`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_EOF``
+      - 0x00000000
+      - End Of Frame. The buffer timestamp has been taken when the last
+	pixel of the frame has been received or the last pixel of the
+	frame has been transmitted. In practice, software generated
+	timestamps will typically be read from the clock a small amount of
+	time after the last pixel has been received or transmitten,
+	depending on the system and other activity in it.
+    * .. _`V4L2-BUF-FLAG-TSTAMP-SRC-SOE`:
+
+      - ``V4L2_BUF_FLAG_TSTAMP_SRC_SOE``
+      - 0x00010000
+      - Start Of Exposure. The buffer timestamp has been taken when the
+	exposure of the frame has begun. This is only valid for the
+	``V4L2_BUF_TYPE_VIDEO_CAPTURE`` buffer type.

+****************************
+Defining Colorspaces in V4L2
+****************************
+
+In V4L2 colorspaces are defined by four values. The first is the
+colorspace identifier (enum :c:type:`v4l2_colorspace`)
+which defines the chromaticities, the default transfer function, the
+default Y'CbCr encoding and the default quantization method. The second
+is the transfer function identifier (enum
+:c:type:`v4l2_xfer_func`) to specify non-standard
+transfer functions. The third is the Y'CbCr encoding identifier (enum
+:c:type:`v4l2_ycbcr_encoding`) to specify
+non-standard Y'CbCr encodings and the fourth is the quantization
+identifier (enum :c:type:`v4l2_quantization`) to
+specify non-standard quantization methods. Most of the time only the
+colorspace field of struct :c:type:`v4l2_pix_format`
+or struct :c:type:`v4l2_pix_format_mplane`
+needs to be filled in.
+
+.. _hsv-colorspace:
+
+On :ref:`HSV formats <hsv-formats>` the *Hue* is defined as the angle on
+the cylindrical color representation. Usually this angle is measured in
+degrees, i.e. 0-360. When we map this angle value into 8 bits, there are
+two basic ways to do it: Divide the angular value by 2 (0-179), or use the
+whole range, 0-255, dividing the angular value by 1.41. The enum
+:c:type:`v4l2_hsv_encoding` specifies which encoding is used.
+
+.. note:: The default R'G'B' quantization is full range for all
+   colorspaces except for BT.2020 which uses limited range R'G'B'
+   quantization.

+
+Colorspace SMPTE 170M (V4L2_COLORSPACE_SMPTE170M)
+=================================================
+
+The :ref:`smpte170m` standard defines the colorspace used by NTSC and
+PAL and by SDTV in general. The default transfer function is
+``V4L2_XFER_FUNC_709``. The default Y'CbCr encoding is
+``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited
+range. The chromaticities of the primary colors and the white reference
+are:

+    * - White Reference (D65)
+      - 0.3127
+      - 0.3290
+
+
+The red, green and blue chromaticities are also often referred to as the
+SMPTE C set, so this colorspace is sometimes called SMPTE C as well.
+
+The transfer function defined for SMPTE 170M is the same as the one
+defined in Rec. 709.
+
+.. math::
+
+    L' = -1.099(-L)^{0.45} + 0.099 \text{, for } L \le-0.018
+
+    L' = 4.5L \text{, for } -0.018 < L < 0.018
+
+    L' = 1.099L^{0.45} - 0.099 \text{, for } L \ge 0.018
+
+Inverse Transfer function:
+
+.. math::
+
+    L = -\left( \frac{L' - 0.099}{-1.099} \right) ^{\frac{1}{0.45}} \text{, for } L' \le -0.081
+
+    L = \frac{L'}{4.5} \text{, for } -0.081 < L' < 0.081
+
+    L = \left(\frac{L' + 0.099}{1.099}\right)^{\frac{1}{0.45} } \text{, for } L' \ge 0.081
+
+The luminance (Y') and color difference (Cb and Cr) are obtained with
+the following ``V4L2_YCBCR_ENC_601`` encoding:
+
+.. math::
+
+    Y' = 0.2990R' + 0.5870G' + 0.1140B'
+
+    Cb = -0.1687R' - 0.3313G' + 0.5B'
+
+    Cr = 0.5R' - 0.4187G' - 0.0813B'
+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
+[-0.5…0.5]. This conversion to Y'CbCr is identical to the one defined in
+the :ref:`itu601` standard and this colorspace is sometimes called
+BT.601 as well, even though BT.601 does not mention any color primaries.
+
+The default quantization is limited range, but full range is possible
+although rarely seen.

+
+.. _col-rec709:
+
+Colorspace Rec. 709 (V4L2_COLORSPACE_REC709)
+============================================
+
+The :ref:`itu709` standard defines the colorspace used by HDTV in
+general. The default transfer function is ``V4L2_XFER_FUNC_709``. The
+default Y'CbCr encoding is ``V4L2_YCBCR_ENC_709``. The default Y'CbCr
+quantization is limited range. The chromaticities of the primary colors

+Transfer function. Normally L is in the range [0…1], but for the
+extended gamut xvYCC encoding values outside that range are allowed.
+
+.. math::
+
+    L' = -1.099(-L)^{0.45} + 0.099 \text{, for } L \le -0.018
+
+    L' = 4.5L \text{, for } -0.018 < L < 0.018
+
+    L' = 1.099L^{0.45} - 0.099 \text{, for } L \ge 0.018
+

+
+    L = -\left( \frac{L' - 0.099}{-1.099} \right)^\frac{1}{0.45} \text{, for } L' \le -0.081
+
+    L = \frac{L'}{4.5}\text{, for } -0.081 < L' < 0.081
+
+    L = \left(\frac{L' + 0.099}{1.099}\right)^{\frac{1}{0.45} } \text{, for } L' \ge 0.081
+
+The luminance (Y') and color difference (Cb and Cr) are obtained with
+the following ``V4L2_YCBCR_ENC_709`` encoding:
+
+.. math::
+
+    Y' = 0.2126R' + 0.7152G' + 0.0722B'
+
+    Cb = -0.1146R' - 0.3854G' + 0.5B'
+
+    Cr = 0.5R' - 0.4542G' - 0.0458B'
+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
+[-0.5…0.5].
+
+The default quantization is limited range, but full range is possible
+although rarely seen.
+
+The ``V4L2_YCBCR_ENC_709`` encoding described above is the default for
+this colorspace, but it can be overridden with ``V4L2_YCBCR_ENC_601``,
+in which case the BT.601 Y'CbCr encoding is used.
+
+Two additional extended gamut Y'CbCr encodings are also possible with
+this colorspace:
+
+The xvYCC 709 encoding (``V4L2_YCBCR_ENC_XV709``, :ref:`xvycc`) is
+similar to the Rec. 709 encoding, but it allows for R', G' and B' values
+that are outside the range [0…1]. The resulting Y', Cb and Cr values are
+scaled and offset according to the limited range formula:
+
+.. math::
+
+    Y' = \frac{219}{256} * (0.2126R' + 0.7152G' + 0.0722B') + \frac{16}{256}
+
+    Cb = \frac{224}{256} * (-0.1146R' - 0.3854G' + 0.5B')
+
+    Cr = \frac{224}{256} * (0.5R' - 0.4542G' - 0.0458B')
+
+The xvYCC 601 encoding (``V4L2_YCBCR_ENC_XV601``, :ref:`xvycc`) is
+similar to the BT.601 encoding, but it allows for R', G' and B' values
+that are outside the range [0…1]. The resulting Y', Cb and Cr values are
+scaled and offset according to the limited range formula:
+
+.. math::
+
+    Y' = \frac{219}{256} * (0.2990R' + 0.5870G' + 0.1140B') + \frac{16}{256}
+
+    Cb = \frac{224}{256} * (-0.1687R' - 0.3313G' + 0.5B')
+
+    Cr = \frac{224}{256} * (0.5R' - 0.4187G' - 0.0813B')
+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
+[-0.5…0.5] and quantized without further scaling or offsets.
+The non-standard xvYCC 709 or xvYCC 601 encodings can be
+used by selecting ``V4L2_YCBCR_ENC_XV709`` or ``V4L2_YCBCR_ENC_XV601``.
+As seen by the xvYCC formulas these encodings always use limited range quantization,
+there is no full range variant. The whole point of these extended gamut encodings
+is that values outside the limited range are still valid, although they
+map to R', G' and B' values outside the [0…1] range and are therefore outside
+the Rec. 709 colorspace gamut.
+
+
+.. _col-srgb:
+
+Colorspace sRGB (V4L2_COLORSPACE_SRGB)
+======================================
+
+The :ref:`srgb` standard defines the colorspace used by most webcams
+and computer graphics. The default transfer function is
+``V4L2_XFER_FUNC_SRGB``. The default Y'CbCr encoding is
+``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited range.
+
+Note that the :ref:`sycc` standard specifies full range quantization,
+however all current capture hardware supported by the kernel convert
+R'G'B' to limited range Y'CbCr. So choosing full range as the default
+would break how applications interpret the quantization range.
+
+The chromaticities of the primary colors and the white reference are:
+
+
+
+.. tabularcolumns:: |p{4.4cm}|p{4.4cm}|p{8.7cm}|
+
+.. flat-table:: sRGB Chromaticities

+    * - White Reference (D65)

+
+
+These chromaticities are identical to the Rec. 709 colorspace.

+Transfer function. Note that negative values for L are only used by the
+Y'CbCr conversion.
+
+.. math::
+
+    L' = -1.055(-L)^{\frac{1}{2.4} } + 0.055\text{, for }L < -0.0031308
+
+    L' = 12.92L\text{, for }-0.0031308 \le L \le 0.0031308
+
+    L' = 1.055L ^{\frac{1}{2.4} } - 0.055\text{, for }0.0031308 < L \le 1
+
+Inverse Transfer function:
+
+.. math::
+
+    L = -((-L' + 0.055) / 1.055) ^{2.4}\text{, for }L' < -0.04045
+
+    L = L' / 12.92\text{, for }-0.04045 \le L' \le 0.04045
+
+    L = ((L' + 0.055) / 1.055) ^{2.4}\text{, for }L' > 0.04045
+
+The luminance (Y') and color difference (Cb and Cr) are obtained with
+the following ``V4L2_YCBCR_ENC_601`` encoding as defined by :ref:`sycc`:
+
+.. math::
+
+    Y' = 0.2990R' + 0.5870G' + 0.1140B'
+
+    Cb = -0.1687R' - 0.3313G' + 0.5B'
+
+    Cr = 0.5R' - 0.4187G' - 0.0813B'
+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
+[-0.5…0.5]. This transform is identical to one defined in SMPTE
+170M/BT.601. The Y'CbCr quantization is limited range.
+
+
+.. _col-oprgb:
+
+Colorspace opRGB (V4L2_COLORSPACE_OPRGB)
+===============================================
+
+The :ref:`oprgb` standard defines the colorspace used by computer
+graphics that use the opRGB colorspace. The default transfer function is
+``V4L2_XFER_FUNC_OPRGB``. The default Y'CbCr encoding is
+``V4L2_YCBCR_ENC_601``. The default Y'CbCr quantization is limited
+range.
+
+Note that the :ref:`oprgb` standard specifies full range quantization,
+however all current capture hardware supported by the kernel convert
+R'G'B' to limited range Y'CbCr. So choosing full range as the default
+would break how applications interpret the quantization range.

+Transfer Function SMPTE 2084 (V4L2_XFER_FUNC_SMPTE2084)
+=======================================================
+
+The :ref:`smpte2084` standard defines the transfer function used by
+High Dynamic Range content.
+
+Constants:
+    m1 = (2610 / 4096) / 4
+
+    m2 = (2523 / 4096) * 128
+
+    c1 = 3424 / 4096
+
+    c2 = (2413 / 4096) * 32
+
+    c3 = (2392 / 4096) * 32
+
+Transfer function:
+    L' = ((c1 + c2 * L\ :sup:`m1`) / (1 + c3 * L\ :sup:`m1`))\ :sup:`m2`
+
+Inverse Transfer function:
+    L = (max(L':sup:`1/m2` - c1, 0) / (c2 - c3 *
+    L'\ :sup:`1/m2`))\ :sup:`1/m1`
+
+Take care when converting between this transfer function and non-HDR transfer
+functions: the linear RGB values [0…1] of HDR content map to a luminance range
+of 0 to 10000 cd/m\ :sup:`2` whereas the linear RGB values of non-HDR (aka
+Standard Dynamic Range or SDR) map to a luminance range of 0 to 100 cd/m\ :sup:`2`.
+
+To go from SDR to HDR you will have to divide L by 100 first. To go in the other
+direction you will have to multiply L by 100. Of course, this clamps all
+luminance values over 100 cd/m\ :sup:`2` to 100 cd/m\ :sup:`2`.
+
+There are better methods, see e.g. :ref:`colimg` for more in-depth information
+about this.

+***********
+Colorspaces
+***********
+
+'Color' is a very complex concept and depends on physics, chemistry and
+biology. Just because you have three numbers that describe the 'red',
+'green' and 'blue' components of the color of a pixel does not mean that
+you can accurately display that color. A colorspace defines what it
+actually *means* to have an RGB value of e.g. (255, 0, 0). That is,
+which color should be reproduced on the screen in a perfectly calibrated
+environment.
+
+In order to do that we first need to have a good definition of color,
+i.e. some way to uniquely and unambiguously define a color so that
+someone else can reproduce it. Human color vision is trichromatic since
+the human eye has color receptors that are sensitive to three different
+wavelengths of light. Hence the need to use three numbers to describe
+color. Be glad you are not a mantis shrimp as those are sensitive to 12
+different wavelengths, so instead of RGB we would be using the
+ABCDEFGHIJKL colorspace...
+
+Color exists only in the eye and brain and is the result of how strongly
+color receptors are stimulated. This is based on the Spectral Power
+Distribution (SPD) which is a graph showing the intensity (radiant
+power) of the light at wavelengths covering the visible spectrum as it
+enters the eye. The science of colorimetry is about the relationship
+between the SPD and color as perceived by the human brain.
+
+Since the human eye has only three color receptors it is perfectly
+possible that different SPDs will result in the same stimulation of
+those receptors and are perceived as the same color, even though the SPD
+of the light is different.
+
+In the 1920s experiments were devised to determine the relationship
+between SPDs and the perceived color and that resulted in the CIE 1931
+standard that defines spectral weighting functions that model the
+perception of color. Specifically that standard defines functions that
+can take an SPD and calculate the stimulus for each color receptor.
+After some further mathematical transforms these stimuli are known as
+the *CIE XYZ tristimulus* values and these X, Y and Z values describe a
+color as perceived by a human unambiguously. These X, Y and Z values are
+all in the range [0…1].
+
+The Y value in the CIE XYZ colorspace corresponds to luminance. Often
+the CIE XYZ colorspace is transformed to the normalized CIE xyY
+colorspace:
+
+	x = X / (X + Y + Z)
+
+	y = Y / (X + Y + Z)
+
+The x and y values are the chromaticity coordinates and can be used to
+define a color without the luminance component Y. It is very confusing
+to have such similar names for these colorspaces. Just be aware that if
+colors are specified with lower case 'x' and 'y', then the CIE xyY
+colorspace is used. Upper case 'X' and 'Y' refer to the CIE XYZ
+colorspace. Also, y has nothing to do with luminance. Together x and y
+specify a color, and Y the luminance. That is really all you need to
+remember from a practical point of view. At the end of this section you
+will find reading resources that go into much more detail if you are
+interested.
+
+A monitor or TV will reproduce colors by emitting light at three
+different wavelengths, the combination of which will stimulate the color
+receptors in the eye and thus cause the perception of color.
+Historically these wavelengths were defined by the red, green and blue
+phosphors used in the displays. These *color primaries* are part of what
+defines a colorspace.
+
+Different display devices will have different primaries and some
+primaries are more suitable for some display technologies than others.
+This has resulted in a variety of colorspaces that are used for
+different display technologies or uses. To define a colorspace you need
+to define the three color primaries (these are typically defined as x, y
+chromaticity coordinates from the CIE xyY colorspace) but also the white
+reference: that is the color obtained when all three primaries are at
+maximum power. This determines the relative power or energy of the
+primaries. This is usually chosen to be close to daylight which has been
+defined as the CIE D65 Illuminant.
+
+To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
+Other colorspaces are defined by three chromaticity coordinates defined
+in the CIE xyY colorspace. Based on those a 3x3 matrix can be
+constructed that transforms CIE XYZ colors to colors in the new
+colorspace.
+
+Both the CIE XYZ and the RGB colorspace that are derived from the
+specific chromaticity primaries are linear colorspaces. But neither the
+eye, nor display technology is linear. Doubling the values of all
+components in the linear colorspace will not be perceived as twice the
+intensity of the color. So each colorspace also defines a transfer
+function that takes a linear color component value and transforms it to
+the non-linear component value, which is a closer match to the
+non-linear performance of both the eye and displays. Linear component
+values are denoted RGB, non-linear are denoted as R'G'B'. In general
+colors used in graphics are all R'G'B', except in openGL which uses
+linear RGB. Special care should be taken when dealing with openGL to
+provide linear RGB colors or to use the built-in openGL support to apply
+the inverse transfer function.
+
+The final piece that defines a colorspace is a function that transforms
+non-linear R'G'B' to non-linear Y'CbCr. This function is determined by
+the so-called luma coefficients. There may be multiple possible Y'CbCr
+encodings allowed for the same colorspace. Many encodings of color
+prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the
+human eye is more sensitive to differences in luminance than in color
+this encoding allows one to reduce the amount of color information
+compared to the luma data. Note that the luma (Y') is unrelated to the Y
+in the CIE XYZ colorspace. Also note that Y'CbCr is often called YCbCr
+or YUV even though these are strictly speaking wrong.
+
+Sometimes people confuse Y'CbCr as being a colorspace. This is not
+correct, it is just an encoding of an R'G'B' color into luma and chroma
+values. The underlying colorspace that is associated with the R'G'B'
+color is also associated with the Y'CbCr color.
+
+The final step is how the RGB, R'G'B' or Y'CbCr values are quantized.
+The CIE XYZ colorspace where X, Y and Z are in the range [0…1] describes
+all colors that humans can perceive, but the transform to another
+colorspace will produce colors that are outside the [0…1] range. Once
+clamped to the [0…1] range those colors can no longer be reproduced in
+that colorspace. This clamping is what reduces the extent or gamut of
+the colorspace. How the range of [0…1] is translated to integer values
+in the range of [0…255] (or higher, depending on the color depth) is
+called the quantization. This is *not* part of the colorspace
+definition. In practice RGB or R'G'B' values are full range, i.e. they
+use the full [0…255] range. Y'CbCr values on the other hand are limited
+range with Y' using [16…235] and Cb and Cr using [16…240].
+
+Unfortunately, in some cases limited range RGB is also used where the
+components use the range [16…235]. And full range Y'CbCr also exists
+using the [0…255] range.
+
+In order to correctly interpret a color you need to know the
+quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr
+encoding and the colorspace. From that information you can calculate the
+corresponding CIE XYZ color and map that again to whatever colorspace
+your display device uses.
+
+The colorspace definition itself consists of the three chromaticity
+primaries, the white reference chromaticity, a transfer function and the
+luma coefficients needed to transform R'G'B' to Y'CbCr. While some
+colorspace standards correctly define all four, quite often the
+colorspace standard only defines some, and you have to rely on other
+standards for the missing pieces. The fact that colorspaces are often a
+mix of different standards also led to very confusing naming conventions
+where the name of a standard was used to name a colorspace when in fact
+that standard was part of various other colorspaces as well.
+
+If you want to read more about colors and colorspaces, then the
+following resources are useful: :ref:`poynton` is a good practical
+book for video engineers, :ref:`colimg` has a much broader scope and
+describes many more aspects of color (physics, chemistry, biology,
+etc.). The
+`http://www.brucelindbloom.com <http://www.brucelindbloom.com>`__
+website is an excellent resource, especially with respect to the
+mathematics behind colorspace conversions. The wikipedia
+`CIE 1931 colorspace <http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space>`__
+article is also very useful.

+Programming a V4L2 device consists of these steps:
+
+-  Opening the device
+
+-  Changing device properties, selecting a video and audio input, video
+   standard, picture brightness a. o.
+
+-  Negotiating a data format
+
+-  Negotiating an input/output method
+
+-  The actual input/output loop
+
+-  Closing the device
+
+In practice most steps are optional and can be executed out of order. It
+depends on the V4L2 device type, you can read about the details in
+:ref:`devices`. In this chapter we will discuss the basic concepts
+applicable to all devices.

+
+*************
+User Controls
+*************
+
+Devices typically have a number of user-settable controls such as
+brightness, saturation and so on, which would be presented to the user
+on a graphical user interface. But, different devices will have
+different controls available, and furthermore, the range of possible
+values, and the default value will vary from device to device. The
+control ioctls provide the information and a mechanism to create a nice
+user interface for these controls that will work correctly with any
+device.
+
+All controls are accessed using an ID value. V4L2 defines several IDs
+for specific purposes. Drivers can also implement their own custom
+controls using ``V4L2_CID_PRIVATE_BASE``  [#f1]_ and higher values. The
+pre-defined control IDs have the prefix ``V4L2_CID_``, and are listed in
+:ref:`control-id`. The ID is used when querying the attributes of a
+control, and when getting or setting the current value.
+
+Generally applications should present controls to the user without
+assumptions about their purpose. Each control comes with a name string
+the user is supposed to understand. When the purpose is non-intuitive
+the driver writer should provide a user manual, a user interface plug-in
+or a driver specific panel application. Predefined IDs were introduced
+to change a few controls programmatically, for example to mute a device
+during a channel switch.
+
+Drivers may enumerate different controls after switching the current
+video input or output, tuner or modulator, or audio input or output.
+Different in the sense of other bounds, another default and current
+value, step size or other menu items. A control with a certain *custom*
+ID can also change name and type.
+
+If a control is not applicable to the current configuration of the
+device (for example, it doesn't apply to the current video input)
+drivers set the ``V4L2_CTRL_FLAG_INACTIVE`` flag.
+
+Control values are stored globally, they do not change when switching
+except to stay within the reported bounds. They also do not change e. g.
+when the device is opened or closed, when the tuner radio frequency is
+changed or generally never without application request.
+
+V4L2 specifies an event mechanism to notify applications when controls
+change value (see
+:ref:`VIDIOC_SUBSCRIBE_EVENT`, event
+``V4L2_EVENT_CTRL``), panel applications might want to make use of that
+in order to always reflect the correct control value.
+
+All controls use machine endianness.
+
+
+.. _control-id:
+
+Control IDs
+===========
+
+``V4L2_CID_BASE``
+    First predefined ID, equal to ``V4L2_CID_BRIGHTNESS``.
+
+``V4L2_CID_USER_BASE``
+    Synonym of ``V4L2_CID_BASE``.
+
+``V4L2_CID_BRIGHTNESS`` ``(integer)``
+    Picture brightness, or more precisely, the black level.
+
+``V4L2_CID_CONTRAST`` ``(integer)``
+    Picture contrast or luma gain.
+
+``V4L2_CID_SATURATION`` ``(integer)``
+    Picture color saturation or chroma gain.
+
+``V4L2_CID_HUE`` ``(integer)``
+    Hue or color balance.
+
+``V4L2_CID_AUDIO_VOLUME`` ``(integer)``
+    Overall audio volume. Note some drivers also provide an OSS or ALSA
+    mixer interface.
+
+``V4L2_CID_AUDIO_BALANCE`` ``(integer)``
+    Audio stereo balance. Minimum corresponds to all the way left,
+    maximum to right.
+
+``V4L2_CID_AUDIO_BASS`` ``(integer)``
+    Audio bass adjustment.
+
+``V4L2_CID_AUDIO_TREBLE`` ``(integer)``
+    Audio treble adjustment.
+
+``V4L2_CID_AUDIO_MUTE`` ``(boolean)``
+    Mute audio, i. e. set the volume to zero, however without affecting
+    ``V4L2_CID_AUDIO_VOLUME``. Like ALSA drivers, V4L2 drivers must mute
+    at load time to avoid excessive noise. Actually the entire device
+    should be reset to a low power consumption state.
+
+``V4L2_CID_AUDIO_LOUDNESS`` ``(boolean)``
+    Loudness mode (bass boost).
+
+``V4L2_CID_BLACK_LEVEL`` ``(integer)``
+    Another name for brightness (not a synonym of
+    ``V4L2_CID_BRIGHTNESS``). This control is deprecated and should not
+    be used in new drivers and applications.
+
+``V4L2_CID_AUTO_WHITE_BALANCE`` ``(boolean)``
+    Automatic white balance (cameras).
+
+``V4L2_CID_DO_WHITE_BALANCE`` ``(button)``
+    This is an action control. When set (the value is ignored), the
+    device will do a white balance and then hold the current setting.
+    Contrast this with the boolean ``V4L2_CID_AUTO_WHITE_BALANCE``,
+    which, when activated, keeps adjusting the white balance.
+
+``V4L2_CID_RED_BALANCE`` ``(integer)``
+    Red chroma balance.

+    rotation angle selected.
+
+``V4L2_CID_BG_COLOR`` ``(integer)``
+    Sets the background color on the current output device. Background
+    color needs to be specified in the RGB24 format. The supplied 32 bit

+
+``V4L2_CID_ILLUMINATORS_1 V4L2_CID_ILLUMINATORS_2`` ``(boolean)``

+
+``V4L2_CID_MIN_BUFFERS_FOR_OUTPUT`` ``(integer)``
+    This is a read-only control that can be read by the application and

+    necessary for hardware to work.
+
+.. _v4l2-alpha-component:
+
+``V4L2_CID_ALPHA_COMPONENT`` ``(integer)``
+    Sets the alpha color component. When a capture device (or capture
+    queue of a mem-to-mem device) produces a frame format that includes
+    an alpha component (e.g.
+    :ref:`packed RGB image formats <pixfmt-rgb>`) and the alpha value
+    is not defined by the device or the mem-to-mem input data this
+    control lets you select the alpha component value of all pixels.
+    When an output device (or output queue of a mem-to-mem device)
+    consumes a frame format that doesn't include an alpha component and
+    the device supports alpha channel processing this control lets you
+    set the alpha component value of all pixels for further processing
+    in the device.
+
+``V4L2_CID_LASTP1``
+    End of the predefined control IDs (currently
+    ``V4L2_CID_ALPHA_COMPONENT`` + 1).
+
+``V4L2_CID_PRIVATE_BASE``
+    ID of the first custom (driver specific) control. Applications
+    depending on particular custom controls should check the driver name
+    and version, see :ref:`querycap`.
+
+Applications can enumerate the available controls with the
+:ref:`VIDIOC_QUERYCTRL` and
+:ref:`VIDIOC_QUERYMENU <VIDIOC_QUERYCTRL>` ioctls, get and set a
+control value with the :ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls. Drivers must implement
+``VIDIOC_QUERYCTRL``, ``VIDIOC_G_CTRL`` and ``VIDIOC_S_CTRL`` when the
+device has one or more controls, ``VIDIOC_QUERYMENU`` when it has one or
+more menu type controls.

+   The use of ``V4L2_CID_PRIVATE_BASE`` is problematic because different
+   drivers may use the same ``V4L2_CID_PRIVATE_BASE`` ID for different
+   controls. This makes it hard to programmatically set such controls
+   since the meaning of the control with that ID is driver dependent. In
+   order to resolve this drivers use unique IDs and the
+   ``V4L2_CID_PRIVATE_BASE`` IDs are mapped to those unique IDs by the
+   kernel. Consider these ``V4L2_CID_PRIVATE_BASE`` IDs as aliases to
+   the real IDs.
+
+   Many applications today still use the ``V4L2_CID_PRIVATE_BASE`` IDs
+   instead of using :ref:`VIDIOC_QUERYCTRL` with
+   the ``V4L2_CTRL_FLAG_NEXT_CTRL`` flag to enumerate all IDs, so
+   support for ``V4L2_CID_PRIVATE_BASE`` is still around.

+*****************************************************
+Image Cropping, Insertion and Scaling -- the CROP API
+*****************************************************
+
+.. note::
+
+   The CROP API is mostly superseded by the newer :ref:`SELECTION API
+   <selection-api>`. The new API should be preferred in most cases,
+   with the exception of pixel aspect ratio detection, which is
+   implemented by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` and has no
+   equivalent in the SELECTION API. See :ref:`selection-vs-crop` for a
+   comparison of the two APIs.
+
+Some video capture devices can sample a subsection of the picture and
+shrink or enlarge it to an image of arbitrary size. We call these
+abilities cropping and scaling. Some video output devices can scale an
+image up or down and insert it at an arbitrary scan line and horizontal
+offset into a video signal.
+
+Applications can use the following API to select an area in the video
+signal, query the default area and the hardware limits.
+
+.. note::
+
+   Despite their name, the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`,
+   :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP
+   <VIDIOC_G_CROP>` ioctls apply to input as well as output devices.
+
+Scaling requires a source and a target. On a video capture or overlay
+device the source is the video signal, and the cropping ioctls determine
+the area actually sampled. The target are images read by the application
+or overlaid onto the graphics screen. Their size (and position for an
+overlay) is negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls.
+
+On a video output device the source are the images passed in by the
+application, and their size is again negotiated with the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctls, or may be encoded in a compressed video stream. The target is
+the video signal, and the cropping ioctls determine the area where the
+images are inserted.
+
+Source and target rectangles are defined even if the device does not
+support scaling or the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctls. Their size (and position
+where applicable) will be fixed in this case.
+
+.. note::
+
+   All capture and output devices that support the CROP or SELECTION
+   API will also support the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`
+   ioctl.
+
+Cropping Structures
+===================
+
+
+.. _crop-scale:
+
+.. kernel-figure:: crop.svg
+    :alt:    crop.svg
+    :align:  center
+
+    Image Cropping, Insertion and Scaling
+
+    The cropping, insertion and scaling process
+
+
+
+For capture devices the coordinates of the top left corner, width and
+height of the area which can be sampled is given by the ``bounds``
+substructure of the struct :c:type:`v4l2_cropcap` returned
+by the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` ioctl. To support a wide
+range of hardware this specification does not define an origin or units.
+However by convention drivers should horizontally count unscaled samples
+relative to 0H (the leading edge of the horizontal sync pulse, see
+:ref:`vbi-hsync`). Vertically ITU-R line numbers of the first field
+(see ITU R-525 line numbering for :ref:`525 lines <vbi-525>` and for
+:ref:`625 lines <vbi-625>`), multiplied by two if the driver
+can capture both fields.
+
+The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by struct
+:c:type:`v4l2_crop` using the same coordinate system as
+struct :c:type:`v4l2_cropcap`. Applications can use the
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>`
+ioctls to get and set this rectangle. It must lie completely within the
+capture boundaries and the driver may further adjust the requested size
+and/or position according to hardware limitations.
+
+Each capture device has a default source rectangle, given by the
+``defrect`` substructure of struct
+:c:type:`v4l2_cropcap`. The center of this rectangle
+shall align with the center of the active picture area of the video
+signal, and cover what the driver writer considers the complete picture.
+Drivers shall reset the source rectangle to the default when the driver
+is first loaded, but not later.
+
+For output devices these structures and ioctls are used accordingly,
+defining the *target* rectangle where the images will be inserted into
+the video signal.
+
+
+Scaling Adjustments
+===================
+
+Video hardware can have various cropping, insertion and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in horizontal and vertical
+direction. Also it may not support scaling at all. At the same time the
+struct :c:type:`v4l2_crop` rectangle may have to be aligned,
+and both the source and target rectangles may have arbitrary upper and
+lower size limits. In particular the maximum ``width`` and ``height`` in
+struct :c:type:`v4l2_crop` may be smaller than the struct
+:c:type:`v4l2_cropcap`. ``bounds`` area. Therefore, as
+usual, drivers are expected to adjust the requested parameters and
+return the actual values selected.
+
+Applications can change the source or the target rectangle first, as
+they may prefer a particular image size or a certain area in the video
+signal. If the driver has to adjust both to satisfy hardware
+limitations, the last requested rectangle shall take priority, and the
+driver should preferably adjust the opposite one. The
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl however shall not change
+the driver state and therefore only adjust the requested rectangle.
+
+Suppose scaling on a video capture device is restricted to a factor 1:1
+or 2:1 in either direction and the target image size must be a multiple
+of 16 × 16 pixels. The source cropping rectangle is set to defaults,
+which are also the upper limit in this example, of 640 × 400 pixels at
+offset 0, 0. An application requests an image size of 300 × 225 pixels,
+assuming video will be scaled down from the "full picture" accordingly.
+The driver sets the image size to the closest possible values 304 × 224,
+then chooses the cropping rectangle closest to the requested size, that
+is 608 × 224 (224 × 2:1 would exceed the limit 400). The offset 0, 0 is
+still valid, thus unmodified. Given the default cropping rectangle
+reported by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` the application can
+easily propose another offset to center the cropping rectangle.
+
+Now the application may insist on covering an area using a picture
+aspect ratio closer to the original request, so it asks for a cropping
+rectangle of 608 × 456 pixels. The present scaling factors limit
+cropping to 640 × 384, so the driver returns the cropping size 608 × 384
+and adjusts the image size to closest possible 304 × 192.
+
+
+Examples
+========
+
+Source and target rectangles shall remain unchanged across closing and
+reopening a device, such that piping data into or out of a device will
+work without special preparations. More advanced applications should
+ensure the parameters are suitable before starting I/O.
+
+.. note::
+
+   On the next two examples, a video capture device is assumed;
+   change ``V4L2_BUF_TYPE_VIDEO_CAPTURE`` for other types of device.

+***********************
+Video Capture Interface
+***********************
+
+Video capture devices sample an analog video signal and store the
+digitized images in memory. Today nearly all devices can capture at full
+25 or 30 frames/second. With this interface applications can control the
+capture process and move images from the driver into user space.
+
+Conventionally V4L2 video capture devices are accessed through character
+device special files named ``/dev/video`` and ``/dev/video0`` to
+``/dev/video63`` with major number 81 and minor numbers 0 to 63.
+``/dev/video`` is typically a symbolic link to the preferred video
+device.
+
+.. note:: The same device file names are used for video output devices.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video capture interface set the
+``V4L2_CAP_VIDEO_CAPTURE`` or ``V4L2_CAP_VIDEO_CAPTURE_MPLANE`` flag in
+the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
+functions they may also support the :ref:`video overlay <overlay>`
+(``V4L2_CAP_VIDEO_OVERLAY``) and the :ref:`raw VBI capture <raw-vbi>`
+(``V4L2_CAP_VBI_CAPTURE``) interface. At least one of the read/write or
+streaming I/O methods must be supported. Tuners and audio inputs are
+optional.
+
+
+Supplemental Functions
+======================
+
+Video capture devices shall support :ref:`audio input <audio>`,
+:ref:`tuner`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video input <video>` ioctls must be supported by all video
+capture devices.
+
+
+Image Format Negotiation
+========================
+
+The result of a capture operation is determined by cropping and image
+format parameters. The former select an area of the video picture to
+capture, the latter how images are stored in memory, i. e. in RGB or YUV
+format, the number of bits per pixel or width and height. Together they
+also define how images are scaled in the process.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then reading
+from it as if it was a plain file. Well written V4L2 applications ensure
+they really get what they want, including cropping and scaling.
+
+Cropping initialization at minimum requires to reset the parameters to
+defaults. An example is given in :ref:`crop`.
+
+To query the current image format applications set the ``type`` field of
+a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
+structure. Drivers fill the struct
+:c:type:`v4l2_pix_format` ``pix`` or the struct
+:c:type:`v4l2_pix_format_mplane` ``pix_mp``
+member of the ``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` as above and initialize all
+fields of the struct :c:type:`v4l2_pix_format`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers may adjust the
+parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+does.
+
+Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
+can be used to learn about hardware limitations without disabling I/O or
+possibly time consuming hardware preparations.
+
+The contents of struct :c:type:`v4l2_pix_format` and
+struct :c:type:`v4l2_pix_format_mplane` are
+discussed in :ref:`pixfmt`. See also the specification of the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
+details. Video capture devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
+requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
+
+
+Reading Images
+==============
+
+A video capture device may support the :ref:`read() function <func-read>`
+and/or streaming (:ref:`memory mapping <func-mmap>` or
+:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

+Event Interface
+***************
+
+The V4L2 event interface provides a means for a user to get immediately
+notified on certain conditions taking place on a device. This might
+include start of frame or loss of signal events, for example. Changes in
+the value or state of a V4L2 control can also be reported through
+events.
+
+To receive events, the events the user is interested in first must be
+subscribed using the
+:ref:`VIDIOC_SUBSCRIBE_EVENT` ioctl. Once
+an event is subscribed, the events of subscribed types are dequeueable
+using the :ref:`VIDIOC_DQEVENT` ioctl. Events may be
+unsubscribed using VIDIOC_UNSUBSCRIBE_EVENT ioctl. The special event
+type V4L2_EVENT_ALL may be used to unsubscribe all the events the
+driver supports.
+
+The event subscriptions and event queues are specific to file handles.
+Subscribing an event on one file handle does not affect other file
+handles.
+
+The information on dequeueable events is obtained by using select or
+poll system calls on video devices. The V4L2 events use POLLPRI events
+on poll system call and exceptions on select system call.
+
+Starting with kernel 3.1 certain guarantees can be given with regards to
+events:
+
+1. Each subscribed event has its own internal dedicated event queue.
+   This means that flooding of one event type will not interfere with
+   other event types.
+
+2. If the internal event queue for a particular subscribed event becomes
+   full, then the oldest event in that queue will be dropped.
+
+3. Where applicable, certain event types can ensure that the payload of
+   the oldest event that is about to be dropped will be merged with the
+   payload of the next oldest event. Thus ensuring that no information
+   is lost, but only an intermediate step leading up to that
+   information. See the documentation for the event you want to
+   subscribe to whether this is applicable for that event or not.

+Video Memory-To-Memory Interface
+********************************
+
+A V4L2 memory-to-memory device can compress, decompress, transform, or
+otherwise convert video data from one format into another format, in memory.
+Such memory-to-memory devices set the ``V4L2_CAP_VIDEO_M2M`` or
+``V4L2_CAP_VIDEO_M2M_MPLANE`` capability. Examples of memory-to-memory
+devices are codecs, scalers, deinterlacers or format converters (i.e.
+converting from YUV to RGB).
+
+A memory-to-memory video node acts just like a normal video node, but it
+supports both output (sending frames from memory to the hardware)
+and capture (receiving the processed frames from the hardware into
+memory) stream I/O. An application will have to setup the stream I/O for
+both sides and finally call :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+for both capture and output to start the hardware.
+
+Memory-to-memory devices function as a shared resource: you can
+open the video node multiple times, each application setting up their
+own properties that are local to the file handle, and each can use
+it independently from the others. The driver will arbitrate access to
+the hardware and reprogram it whenever another file handler gets access.
+This is different from the usual video node behavior where the video
+properties are global to the device (i.e. changing something through one
+file handle is visible through another file handle).
+
+One of the most common memory-to-memory device is the codec. Codecs
+are more complicated than most and require additional setup for
+their codec parameters. This is done through codec controls.
+See :ref:`mpeg-controls`. More details on how to use codec memory-to-memory
+devices are given in the following sections.

+
+******************
+Metadata Interface
+******************
+
+Metadata refers to any non-image data that supplements video frames with
+additional information. This may include statistics computed over the image,
+frame capture parameters supplied by the image source or device specific
+parameters for specifying how the device processes images. This interface is
+intended for transfer of metadata between the userspace and the hardware and
+control of that operation.
+
+The metadata interface is implemented on video device nodes. The device can be
+dedicated to metadata or can support both video and metadata as specified in its
+reported capabilities.
+
+Querying Capabilities
+=====================
+
+Device nodes supporting the metadata capture interface set the
+``V4L2_CAP_META_CAPTURE`` flag in the ``device_caps`` field of the
+:c:type:`v4l2_capability` structure returned by the :c:func:`VIDIOC_QUERYCAP`
+ioctl. That flag means the device can capture metadata to memory. Similarly,
+device nodes supporting metadata output interface set the
+``V4L2_CAP_META_OUTPUT`` flag in the ``device_caps`` field of
+:c:type:`v4l2_capability` structure. That flag means the device can read
+metadata from memory.
+
+At least one of the read/write or streaming I/O methods must be supported.
+
+
+Data Format Negotiation
+=======================
+
+The metadata device uses the :ref:`format` ioctls to select the capture format.
+The metadata buffer content format is bound to that selected format. In addition
+to the basic :ref:`format` ioctls, the :c:func:`VIDIOC_ENUM_FMT` ioctl must be
+supported as well.
+
+To use the :ref:`format` ioctls applications set the ``type`` field of the
+:c:type:`v4l2_format` structure to ``V4L2_BUF_TYPE_META_CAPTURE`` or to
+``V4L2_BUF_TYPE_META_OUTPUT`` and use the :c:type:`v4l2_meta_format` ``meta``
+member of the ``fmt`` union as needed per the desired operation. Both drivers
+and applications must set the remainder of the :c:type:`v4l2_format` structure
+to 0.

+******************************
+Video Output Overlay Interface
+******************************
+
+**Also known as On-Screen Display (OSD)**
+
+Some video output devices can overlay a framebuffer image onto the
+outgoing video signal. Applications can set up such an overlay using
+this interface, which borrows structures and ioctls of the
+:ref:`Video Overlay <overlay>` interface.
+
+The OSD function is accessible through the same character special file
+as the :ref:`Video Output <capture>` function.
+
+.. note::
+
+   The default function of such a ``/dev/video`` device is video
+   capturing or output. The OSD function is only available after calling
+   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the *Video Output Overlay* interface set the
+``V4L2_CAP_VIDEO_OUTPUT_OVERLAY`` flag in the ``capabilities`` field of
+struct :c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+
+Framebuffer
+===========
+
+Contrary to the *Video Overlay* interface the framebuffer is normally
+implemented on the TV card and not the graphics card. On Linux it is
+accessible as a framebuffer device (``/dev/fbN``). Given a V4L2 device,
+applications can find the corresponding framebuffer device by calling
+the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` ioctl. It returns, amongst
+other information, the physical address of the framebuffer in the
+``base`` field of struct :c:type:`v4l2_framebuffer`.
+The framebuffer device ioctl ``FBIOGET_FSCREENINFO`` returns the same
+address in the ``smem_start`` field of struct
+struct :c:type:`fb_fix_screeninfo`. The ``FBIOGET_FSCREENINFO``
+ioctl and struct :c:type:`fb_fix_screeninfo` are defined in
+the ``linux/fb.h`` header file.
+
+The width and height of the framebuffer depends on the current video
+standard. A V4L2 driver may reject attempts to change the video standard
+(or any other ioctl which would imply a framebuffer size change) with an
+``EBUSY`` error code until all applications closed the framebuffer device.
+
+Example: Finding a framebuffer device for OSD
+---------------------------------------------
+
+.. code-block:: c
+
+    #include <linux/fb.h>
+
+    struct v4l2_framebuffer fbuf;
+    unsigned int i;
+    int fb_fd;
+
+    if (-1 == ioctl(fd, VIDIOC_G_FBUF, &fbuf)) {
+	perror("VIDIOC_G_FBUF");
+	exit(EXIT_FAILURE);
+    }
+
+    for (i = 0; i < 30; i++) {
+	char dev_name[16];
+	struct fb_fix_screeninfo si;
+
+	snprintf(dev_name, sizeof(dev_name), "/dev/fb%u", i);
+
+	fb_fd = open(dev_name, O_RDWR);
+	if (-1 == fb_fd) {
+	    switch (errno) {
+	    case ENOENT: /* no such file */
+	    case ENXIO:  /* no driver */
+		continue;
+
+	    default:
+		perror("open");
+		exit(EXIT_FAILURE);
+	    }
+	}
+
+	if (0 == ioctl(fb_fd, FBIOGET_FSCREENINFO, &si)) {
+	    if (si.smem_start == (unsigned long)fbuf.base)
+		break;
+	} else {
+	    /* Apparently not a framebuffer device. */
+	}
+
+	close(fb_fd);
+	fb_fd = -1;
+    }
+
+    /* fb_fd is the file descriptor of the framebuffer device
+       for the video output overlay, or -1 if no device was found. */
+
+
+Overlay Window and Scaling
+==========================
+
+The overlay is controlled by source and target rectangles. The source
+rectangle selects a subsection of the framebuffer image to be overlaid,
+the target rectangle an area in the outgoing video signal where the
+image will appear. Drivers may or may not support scaling, and arbitrary
+sizes and positions of these rectangles. Further drivers may support any
+(or none) of the clipping/blending methods defined for the
+:ref:`Video Overlay <overlay>` interface.
+
+A struct :c:type:`v4l2_window` defines the size of the
+source rectangle, its position in the framebuffer and the
+clipping/blending method to be used for the overlay. To get the current
+parameters applications set the ``type`` field of a struct
+:c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
+struct :c:type:`v4l2_window` substructure named ``win``. It is not
+possible to retrieve a previously programmed clipping list or bitmap.
+
+To program the source rectangle applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY``, initialize the ``win``
+substructure and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+The driver adjusts the parameters against hardware limits and returns
+the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
+the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
+about driver capabilities without actually changing driver state. Unlike
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
+
+A struct :c:type:`v4l2_crop` defines the size and position
+of the target rectangle. The scaling factor of the overlay is implied by
+the width and height given in struct :c:type:`v4l2_window`
+and struct :c:type:`v4l2_crop`. The cropping API applies to
+*Video Output* and *Video Output Overlay* devices in the same way as to
+*Video Capture* and *Video Overlay* devices, merely reversing the
+direction of the data flow. For more information see :ref:`crop`.
+
+
+Enabling Overlay
+================
+
+There is no V4L2 ioctl to enable or disable the overlay, however the
+framebuffer interface of the driver may support the ``FBIOBLANK`` ioctl.

+**********************
+Video Output Interface
+**********************
+
+Video output devices encode stills or image sequences as analog video
+signal. With this interface applications can control the encoding
+process and move images from user space to the driver.
+
+Conventionally V4L2 video output devices are accessed through character
+device special files named ``/dev/video`` and ``/dev/video0`` to
+``/dev/video63`` with major number 81 and minor numbers 0 to 63.
+``/dev/video`` is typically a symbolic link to the preferred video
+device.
+
+.. note:: The same device file names are used also for video capture devices.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video output interface set the
+``V4L2_CAP_VIDEO_OUTPUT`` or ``V4L2_CAP_VIDEO_OUTPUT_MPLANE`` flag in
+the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
+functions they may also support the :ref:`raw VBI output <raw-vbi>`
+(``V4L2_CAP_VBI_OUTPUT``) interface. At least one of the read/write or
+streaming I/O methods must be supported. Modulators and audio outputs
+are optional.
+
+
+Supplemental Functions
+======================
+
+Video output devices shall support :ref:`audio output <audio>`,
+:ref:`modulator <tuner>`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video output <video>` ioctls must be supported by all video
+output devices.
+
+
+Image Format Negotiation
+========================
+
+The output is determined by cropping and image format parameters. The
+former select an area of the video picture where the image will appear,
+the latter how images are stored in memory, i. e. in RGB or YUV format,
+the number of bits per pixel or width and height. Together they also
+define how images are scaled in the process.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then writing
+to it as if it was a plain file. Well written V4L2 applications ensure
+they really get what they want, including cropping and scaling.
+
+Cropping initialization at minimum requires to reset the parameters to
+defaults. An example is given in :ref:`crop`.
+
+To query the current image format applications set the ``type`` field of
+a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT`` or ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``
+and call the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer
+to this structure. Drivers fill the struct
+:c:type:`v4l2_pix_format` ``pix`` or the struct
+:c:type:`v4l2_pix_format_mplane` ``pix_mp``
+member of the ``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` as above and initialize all
+fields of the struct :c:type:`v4l2_pix_format`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers may adjust the
+parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+does.
+
+Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
+can be used to learn about hardware limitations without disabling I/O or
+possibly time consuming hardware preparations.
+
+The contents of struct :c:type:`v4l2_pix_format` and
+struct :c:type:`v4l2_pix_format_mplane` are
+discussed in :ref:`pixfmt`. See also the specification of the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
+details. Video output devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
+requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
+
+
+Writing Images
+==============
+
+A video output device may support the :ref:`write() function <rw>`
+and/or streaming (:ref:`memory mapping <mmap>` or
+:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

+***********************
+Video Overlay Interface
+***********************
+
+**Also known as Framebuffer Overlay or Previewing.**
+
+Video overlay devices have the ability to genlock (TV-)video into the
+(VGA-)video signal of a graphics card, or to store captured images
+directly in video memory of a graphics card, typically with clipping.
+This can be considerable more efficient than capturing images and
+displaying them by other means. In the old days when only nuclear power
+plants needed cooling towers this used to be the only way to put live
+video into a window.
+
+Video overlay devices are accessed through the same character special
+files as :ref:`video capture <capture>` devices.
+
+.. note::
+
+   The default function of a ``/dev/video`` device is video
+   capturing. The overlay function is only available after calling
+   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+The driver may support simultaneous overlay and capturing using the
+read/write and streaming I/O methods. If so, operation at the nominal
+frame rate of the video standard is not guaranteed. Frames may be
+directed away from overlay to capture, or one field may be used for
+overlay and the other for capture if the capture parameters permit this.
+
+Applications should use different file descriptors for capturing and
+overlay. This must be supported by all drivers capable of simultaneous
+capturing and overlay. Optionally these drivers may also permit
+capturing and overlay with a single file descriptor for compatibility
+with V4L and earlier versions of V4L2. [#f1]_
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video overlay interface set the
+``V4L2_CAP_VIDEO_OVERLAY`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. The overlay I/O
+method specified below must be supported. Tuners and audio inputs are
+optional.
+
+
+Supplemental Functions
+======================
+
+Video overlay devices shall support :ref:`audio input <audio>`,
+:ref:`tuner`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video input <video>` and :ref:`video standard <standard>`
+ioctls must be supported by all video overlay devices.
+
+
+Setup
+=====
+
+Before overlay can commence applications must program the driver with
+frame buffer parameters, namely the address and size of the frame buffer
+and the image format, for example RGB 5:6:5. The
+:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
+:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls are available to get and
+set these parameters, respectively. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is
+privileged because it allows to set up DMA into physical memory,
+bypassing the memory protection mechanisms of the kernel. Only the
+superuser can change the frame buffer address and size. Users are not
+supposed to run TV applications as root or with SUID bit set. A small
+helper application with suitable privileges should query the graphics
+system and program the V4L2 driver at the appropriate time.
+
+Some devices add the video overlay to the output signal of the graphics
+card. In this case the frame buffer is not modified by the video device,
+and the frame buffer address and pixel format are not needed by the
+driver. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is not privileged. An application
+can check for this type of device by calling the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+ioctl.
+
+A driver may support any (or none) of five clipping/blending methods:
+
+1. Chroma-keying displays the overlaid image only where pixels in the
+   primary graphics surface assume a certain color.
+
+2. A bitmap can be specified where each bit corresponds to a pixel in
+   the overlaid image. When the bit is set, the corresponding video
+   pixel is displayed, otherwise a pixel of the graphics surface.
+
+3. A list of clipping rectangles can be specified. In these regions *no*
+   video is displayed, so the graphics surface can be seen here.
+
+4. The framebuffer has an alpha channel that can be used to clip or
+   blend the framebuffer with the video.
+
+5. A global alpha value can be specified to blend the framebuffer
+   contents with video images.
+
+When simultaneous capturing and overlay is supported and the hardware
+prohibits different image and frame buffer formats, the format requested
+first takes precedence. The attempt to capture
+(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) or overlay
+(:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`) may fail with an ``EBUSY`` error
+code or return accordingly modified parameters..
+
+
+Overlay Window
+==============
+
+The overlaid image is determined by cropping and overlay window
+parameters. The former select an area of the video picture to capture,
+the latter how images are overlaid and clipped. Cropping initialization
+at minimum requires to reset the parameters to defaults. An example is
+given in :ref:`crop`.
+
+The overlay window is described by a struct
+:c:type:`v4l2_window`. It defines the size of the image,
+its position over the graphics surface and the clipping to be applied.
+To get the current parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OVERLAY`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
+struct :c:type:`v4l2_window` substructure named ``win``. It is not
+possible to retrieve a previously programmed clipping list or bitmap.
+
+To program the overlay window applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VIDEO_OVERLAY``, initialize the ``win`` substructure and
+call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. The driver
+adjusts the parameters against hardware limits and returns the actual
+parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
+about driver capabilities without actually changing driver state. Unlike
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
+
+The scaling factor of the overlaid image is implied by the width and
+height given in struct :c:type:`v4l2_window` and the size
+of the cropping rectangle. For more information see :ref:`crop`.
+
+When simultaneous capturing and overlay is supported and the hardware
+prohibits different image and window sizes, the size requested first
+takes precedence. The attempt to capture or overlay as well
+(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) may fail with an ``EBUSY`` error
+code or return accordingly modified parameters.
+
+
+.. c:type:: v4l2_window
+
+struct v4l2_window
+------------------
+
+``struct v4l2_rect w``
+    Size and position of the window relative to the top, left corner of
+    the frame buffer defined with
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The window can extend the
+    frame buffer width and height, the ``x`` and ``y`` coordinates can
+    be negative, and it can lie completely outside the frame buffer. The
+    driver clips the window accordingly, or if that is not possible,
+    modifies its size and/or position.
+
+``enum v4l2_field field``
+    Applications set this field to determine which video field shall be
+    overlaid, typically one of ``V4L2_FIELD_ANY`` (0),
+    ``V4L2_FIELD_TOP``, ``V4L2_FIELD_BOTTOM`` or
+    ``V4L2_FIELD_INTERLACED``. Drivers may have to choose a different
+    field order and return the actual setting here.
+
+``__u32 chromakey``
+    When chroma-keying has been negotiated with
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` applications set this field
+    to the desired pixel value for the chroma key. The format is the
+    same as the pixel format of the framebuffer (struct
+    :c:type:`v4l2_framebuffer` ``fmt.pixelformat``
+    field), with bytes in host order. E. g. for
+    :ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR32>` the value should
+    be 0xRRGGBB on a little endian, 0xBBGGRR on a big endian host.
+
+``struct v4l2_clip * clips``
+    When chroma-keying has *not* been negotiated and
+    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
+    applications can set this field to point to an array of clipping
+    rectangles.
+
+    Like the window coordinates w, clipping rectangles are defined
+    relative to the top, left corner of the frame buffer. However
+    clipping rectangles must not extend the frame buffer width and
+    height, and they must not overlap. If possible applications
+    should merge adjacent rectangles. Whether this must create
+    x-y or y-x bands, or the order of rectangles, is not defined. When
+    clip lists are not supported the driver ignores this field. Its
+    contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+    are undefined.
+
+``__u32 clipcount``
+    When the application set the ``clips`` field, this field must
+    contain the number of clipping rectangles in the list. When clip
+    lists are not supported the driver ignores this field, its contents
+    after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are undefined. When clip lists are
+    supported but no clipping is desired this field must be set to zero.
+
+``void * bitmap``
+    When chroma-keying has *not* been negotiated and
+    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
+    applications can set this field to point to a clipping bit mask.
+
+It must be of the same size as the window, ``w.width`` and ``w.height``.
+Each bit corresponds to a pixel in the overlaid image, which is
+displayed only when the bit is *set*. Pixel coordinates translate to
+bits like:
+
+
+.. code-block:: c
+
+    ((__u8 *) bitmap)[w.width * y + x / 8] & (1 << (x & 7))
+
+where ``0`` ≤ x < ``w.width`` and ``0`` ≤ y <``w.height``. [#f2]_
+
+When a clipping bit mask is not supported the driver ignores this field,
+its contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are
+undefined. When a bit mask is supported but no clipping is desired this
+field must be set to ``NULL``.
+
+Applications need not create a clip list or bit mask. When they pass
+both, or despite negotiating chroma-keying, the results are undefined.
+Regardless of the chosen method, the clipping abilities of the hardware
+may be limited in quantity or quality. The results when these limits are
+exceeded are undefined. [#f3]_
+
+``__u8 global_alpha``
+    The global alpha value used to blend the framebuffer with video
+    images, if global alpha blending has been negotiated
+    (``V4L2_FBUF_FLAG_GLOBAL_ALPHA``, see
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`,
+    :ref:`framebuffer-flags`).
+
+.. note::
+
+   This field was added in Linux 2.6.23, extending the
+   structure. However the :ref:`VIDIOC_[G|S|TRY]_FMT <VIDIOC_G_FMT>`
+   ioctls, which take a pointer to a :c:type:`v4l2_format`
+   parent structure with padding bytes at the end, are not affected.
+
+
+.. c:type:: v4l2_clip
+
+struct v4l2_clip [#f4]_
+-----------------------
+
+``struct v4l2_rect c``
+    Coordinates of the clipping rectangle, relative to the top, left
+    corner of the frame buffer. Only window pixels *outside* all
+    clipping rectangles are displayed.
+
+``struct v4l2_clip * next``
+    Pointer to the next clipping rectangle, ``NULL`` when this is the last
+    rectangle. Drivers ignore this field, it cannot be used to pass a
+    linked list of clipping rectangles.
+
+
+.. c:type:: v4l2_rect
+
+struct v4l2_rect
+----------------
+
+``__s32 left``
+    Horizontal offset of the top, left corner of the rectangle, in
+    pixels.
+
+``__s32 top``
+    Vertical offset of the top, left corner of the rectangle, in pixels.
+    Offsets increase to the right and down.
+
+``__u32 width``
+    Width of the rectangle, in pixels.
+
+``__u32 height``
+    Height of the rectangle, in pixels.
+
+
+Enabling Overlay
+================
+
+To start or stop the frame buffer overlay applications call the
+:ref:`VIDIOC_OVERLAY` ioctl.
+
+.. [#f1]
+   A common application of two file descriptors is the XFree86
+   :ref:`Xv/V4L <xvideo>` interface driver and a V4L2 application.
+   While the X server controls video overlay, the application can take
+   advantage of memory mapping and DMA.
+
+   In the opinion of the designers of this API, no driver writer taking
+   the efforts to support simultaneous capturing and overlay will
+   restrict this ability by requiring a single file descriptor, as in
+   V4L and earlier versions of V4L2. Making this optional means
+   applications depending on two file descriptors need backup routines
+   to be compatible with all drivers, which is considerable more work
+   than using two fds in applications which do not. Also two fd's fit
+   the general concept of one file descriptor for each logical stream.
+   Hence as a complexity trade-off drivers *must* support two file
+   descriptors and *may* support single fd operation.
+
+.. [#f2]
+   Should we require ``w.width`` to be a multiple of eight?
+
+.. [#f3]
+   When the image is written into frame buffer memory it will be
+   undesirable if the driver clips out less pixels than expected,
+   because the application and graphics system are not aware these
+   regions need to be refreshed. The driver should clip out more pixels
+   or not write the image at all.
+
+.. [#f4]
+   The X Window system defines "regions" which are vectors of ``struct
+   BoxRec { short x1, y1, x2, y2; }`` with ``width = x2 - x1`` and
+   ``height = y2 - y1``, so one cannot pass X11 clip lists directly.

+Radio Interface
+***************
+
+This interface is intended for AM and FM (analog) radio receivers and
+transmitters.
+
+Conventionally V4L2 radio devices are accessed through character device
+special files named ``/dev/radio`` and ``/dev/radio0`` to
+``/dev/radio63`` with major number 81 and minor numbers 64 to 127.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the radio interface set the ``V4L2_CAP_RADIO`` and
+``V4L2_CAP_TUNER`` or ``V4L2_CAP_MODULATOR`` flag in the
+``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Other combinations of
+capability flags are reserved for future extensions.
+
+
+Supplemental Functions
+======================
+
+Radio devices can support :ref:`controls <control>`, and must support
+the :ref:`tuner or modulator <tuner>` ioctls.
+
+They do not support the video input or output, audio input or output,
+video standard, cropping and scaling, compression and streaming
+parameter, or overlay ioctls. All other ioctls and I/O methods are
+reserved for future extensions.
+
+
+Programming
+===========
+
+Radio devices may have a couple audio controls (as discussed in
+:ref:`control`) such as a volume control, possibly custom controls.
+Further all radio devices have one tuner or modulator (these are
+discussed in :ref:`tuner`) with index number zero to select the radio
+frequency and to determine if a monaural or FM stereo program is
+received/emitted. Drivers switch automatically between AM and FM
+depending on the selected frequency. The
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` or
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl reports the
+supported frequency range.

+**********************
+Raw VBI Data Interface
+**********************
+
+VBI is an abbreviation of Vertical Blanking Interval, a gap in the
+sequence of lines of an analog video signal. During VBI no picture
+information is transmitted, allowing some time while the electron beam
+of a cathode ray tube TV returns to the top of the screen. Using an
+oscilloscope you will find here the vertical synchronization pulses and
+short data packages ASK modulated [#f1]_ onto the video signal. These are
+transmissions of services such as Teletext or Closed Caption.
+
+Subject of this interface type is raw VBI data, as sampled off a video
+signal, or to be added to a signal for output. The data format is
+similar to uncompressed video images, a number of lines times a number
+of samples per line, we call this a VBI image.
+
+Conventionally V4L2 VBI devices are accessed through character device
+special files named ``/dev/vbi`` and ``/dev/vbi0`` to ``/dev/vbi31``
+with major number 81 and minor numbers 224 to 255. ``/dev/vbi`` is
+typically a symbolic link to the preferred VBI device. This convention
+applies to both input and output devices.
+
+To address the problems of finding related video and VBI devices VBI
+capturing and output is also available as device function under
+``/dev/video``. To capture or output raw VBI data with these devices
+applications must call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+Accessed as ``/dev/vbi``, raw VBI capturing or output is the default
+device function.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the raw VBI capturing or output API set the
+``V4L2_CAP_VBI_CAPTURE`` or ``V4L2_CAP_VBI_OUTPUT`` flags, respectively,
+in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
+read/write, streaming or asynchronous I/O methods must be supported. VBI
+devices may or may not have a tuner or modulator.
+
+
+Supplemental Functions
+======================
+
+VBI devices shall support :ref:`video input or output <video>`,
+:ref:`tuner or modulator <tuner>`, and :ref:`controls <control>`
+ioctls as needed. The :ref:`video standard <standard>` ioctls provide
+information vital to program a VBI device, therefore must be supported.
+
+
+Raw VBI Format Negotiation
+==========================
+
+Raw VBI sampling abilities can vary, in particular the sampling
+frequency. To properly interpret the data V4L2 specifies an ioctl to
+query the sampling parameters. Moreover, to allow for some flexibility
+applications can also suggest different parameters.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then reading
+from it as if it was a plain file. Well written V4L2 applications should
+always ensure they really get what they want, requesting reasonable
+parameters and then checking if the actual parameters are suitable.
+
+To query the current raw VBI capture parameters applications set the
+``type`` field of a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_VBI_CAPTURE`` or ``V4L2_BUF_TYPE_VBI_OUTPUT``, and call
+the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
+structure. Drivers fill the struct
+:c:type:`v4l2_vbi_format` ``vbi`` member of the
+``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` as above and initialize all
+fields of the struct :c:type:`v4l2_vbi_format`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers return an ``EINVAL`` error
+code only when the given parameters are ambiguous, otherwise they modify
+the parameters according to the hardware capabilities and return the
+actual parameters. When the driver allocates resources at this point, it
+may return an ``EBUSY`` error code to indicate the returned parameters are
+valid but the required resources are currently not available. That may
+happen for instance when the video and VBI areas to capture would
+overlap, or when the driver supports multiple opens and another process
+already requested VBI capturing or output. Anyway, applications must
+expect other resource allocation points which may return ``EBUSY``, at the
+:ref:`VIDIOC_STREAMON` ioctl and the first :ref:`read() <func-read>`
+, :ref:`write() <func-write>` and :ref:`select() <func-select>` calls.
+
+VBI devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all requests
+and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.

+	for each field for each 525 or 625 line format as a convenience.

+      - The number of lines in the first and second field image,

+
+	Drivers should be as flexibility as possible. For example, it may
+	be possible to extend or move the VBI capture window down to the
+	picture area, implementing a 'full field mode' to capture data
+	service transmissions embedded in the picture.
+
+	An application can set the first or second ``count`` value to zero
+	if no data is required from the respective field; ``count``\ [1]
+	if the scanning system is progressive, i. e. not interlaced. The
+	corresponding start value shall be ignored by the application and
+	driver. Anyway, drivers may not support single field capturing and
+	return both count values non-zero.
+
+	Both ``count`` values set to zero, or line numbers are outside the
+	bounds depicted\ [#f4]_, or a field image covering lines of two
+	fields, are invalid and shall not be returned by the driver.
+
+	To initialize the ``start`` and ``count`` fields, applications
+	must first determine the current video standard selection. The
+	:ref:`v4l2_std_id <v4l2-std-id>` or the ``framelines`` field

+	for this purpose.
+    * - __u32

+    * - ``V4L2_VBI_UNSYNC``
+      - 0x0001
+      - This flag indicates hardware which does not properly distinguish
+	between fields. Normally the VBI image stores the first field
+	(lower scanning line numbers) first in memory. This may be a top
+	or bottom field depending on the video standard. When this flag is
+	set the first or second field may be stored first, however the
+	fields are still in correct temporal order with the older field
+	first in memory. [#f3]_
+    * - ``V4L2_VBI_INTERLACED``
+      - 0x0002
+      - By default the two field images will be passed sequentially; all
+	lines of the first field followed by all lines of the second field
+	(compare :ref:`field-order` ``V4L2_FIELD_SEQ_TB`` and
+	``V4L2_FIELD_SEQ_BT``, whether the top or bottom field is first in
+	memory depends on the video standard). When this flag is set, the
+	two fields are interlaced (cf. ``V4L2_FIELD_INTERLACED``). The
+	first line of the first field followed by the first line of the
+	second field, then the two second lines, and so on. Such a layout
+	may be necessary when the hardware has been programmed to capture
+	or output interlaced video images and is unable to separate the
+	fields for VBI capturing at the same time. For simplicity setting
+	this flag implies that both ``count`` values are equal and
+	non-zero.

+
+Remember the VBI image format depends on the selected video standard,
+therefore the application must choose a new standard or query the
+current standard first. Attempts to read or write data ahead of format
+negotiation, or after switching the video standard which may invalidate
+the negotiated VBI parameters, should be refused by the driver. A format
+change during active I/O is not permitted.
+
+
+Reading and writing VBI images
+==============================
+
+To assure synchronization with the field number and easier
+implementation, the smallest unit of data passed at a time is one frame,
+consisting of two fields of VBI images immediately following in memory.
+
+The total size of a frame computes as follows:
+
+
+.. code-block:: c
+
+    (count[0] + count[1]) * samples_per_line * sample size in bytes
+
+The sample size is most likely always one byte, applications must check
+the ``sample_format`` field though, to function properly with other
+drivers.
+
+A VBI device may support :ref:`read/write <rw>` and/or streaming
+(:ref:`memory mapping <mmap>` or :ref:`user pointer <userp>`) I/O.
+The latter bears the possibility of synchronizing video and VBI data by
+using buffer timestamps.
+
+Remember the :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` ioctl and the
+first :ref:`read() <func-read>`, :ref:`write() <func-write>` and
+:ref:`select() <func-select>` call can be resource allocation
+points returning an ``EBUSY`` error code if the required hardware resources
+are temporarily unavailable, for example the device is already in use by
+another process.
+
+.. [#f1]
+   ASK: Amplitude-Shift Keying. A high signal level represents a '1'
+   bit, a low level a '0' bit.
+
+.. [#f2]
+   A few devices may be unable to sample VBI data at all but can extend
+   the video capture window to the VBI region.
+
+.. [#f3]
+   Most VBI services transmit on both fields, but some have different
+   semantics depending on the field number. These cannot be reliable

+RDS Interface
+*************
+
+The Radio Data System transmits supplementary information in binary
+format, for example the station name or travel information, on an
+inaudible audio subcarrier of a radio program. This interface is aimed
+at devices capable of receiving and/or transmitting RDS information.
+
+For more information see the core RDS standard :ref:`iec62106` and the
+RBDS standard :ref:`nrsc4`.
+
+.. note::
+
+   Note that the RBDS standard as is used in the USA is almost
+   identical to the RDS standard. Any RDS decoder/encoder can also handle
+   RBDS. Only some of the fields have slightly different meanings. See the
+   RBDS standard for more information.
+
+The RBDS standard also specifies support for MMBS (Modified Mobile
+Search). This is a proprietary format which seems to be discontinued.
+The RDS interface does not support this format. Should support for MMBS
+(or the so-called 'E blocks' in general) be needed, then please contact
+the linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the RDS capturing API set the
+``V4L2_CAP_RDS_CAPTURE`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Any tuner that
+supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
+``capability`` field of struct :c:type:`v4l2_tuner`. If the
+driver only passes RDS blocks without interpreting the data the
+``V4L2_TUNER_CAP_RDS_BLOCK_IO`` flag has to be set, see
+:ref:`Reading RDS data <reading-rds-data>`. For future use the flag
+``V4L2_TUNER_CAP_RDS_CONTROLS`` has also been defined. However, a driver
+for a radio tuner with this capability does not yet exist, so if you are
+planning to write such a driver you should discuss this on the
+linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+Whether an RDS signal is present can be detected by looking at the
+``rxsubchans`` field of struct :c:type:`v4l2_tuner`: the
+``V4L2_TUNER_SUB_RDS`` will be set if RDS data was detected.
+
+Devices supporting the RDS output API set the ``V4L2_CAP_RDS_OUTPUT``
+flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Any modulator that
+supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
+``capability`` field of struct
+:c:type:`v4l2_modulator`. In order to enable the RDS
+transmission one must set the ``V4L2_TUNER_SUB_RDS`` bit in the
+``txsubchans`` field of struct
+:c:type:`v4l2_modulator`. If the driver only passes RDS
+blocks without interpreting the data the ``V4L2_TUNER_CAP_RDS_BLOCK_IO``
+flag has to be set. If the tuner is capable of handling RDS entities
+like program identification codes and radio text, the flag
+``V4L2_TUNER_CAP_RDS_CONTROLS`` should be set, see
+:ref:`Writing RDS data <writing-rds-data>` and
+:ref:`FM Transmitter Control Reference <fm-tx-controls>`.

+**************************************
+Software Defined Radio Interface (SDR)
+**************************************
+
+SDR is an abbreviation of Software Defined Radio, the radio device which
+uses application software for modulation or demodulation. This interface
+is intended for controlling and data streaming of such devices.
+
+SDR devices are accessed through character device special files named
+``/dev/swradio0`` to ``/dev/swradio255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the SDR receiver interface set the
+``V4L2_CAP_SDR_CAPTURE`` and ``V4L2_CAP_TUNER`` flag in the
+``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
+device has an Analog to Digital Converter (ADC), which is a mandatory
+element for the SDR receiver.
+
+Devices supporting the SDR transmitter interface set the
+``V4L2_CAP_SDR_OUTPUT`` and ``V4L2_CAP_MODULATOR`` flag in the
+``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
+device has an Digital to Analog Converter (DAC), which is a mandatory
+element for the SDR transmitter.
+
+At least one of the read/write, streaming or asynchronous I/O methods
+must be supported.
+
+
+Supplemental Functions
+======================
+
+SDR devices can support :ref:`controls <control>`, and must support
+the :ref:`tuner` ioctls. Tuner ioctls are used for setting the
+ADC/DAC sampling rate (sampling frequency) and the possible radio
+frequency (RF).
+
+The ``V4L2_TUNER_SDR`` tuner type is used for setting SDR device ADC/DAC
+frequency, and the ``V4L2_TUNER_RF`` tuner type is used for setting
+radio frequency. The tuner index of the RF tuner (if any) must always
+follow the SDR tuner index. Normally the SDR tuner is #0 and the RF
+tuner is #1.
+
+The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl is
+not supported.
+
+
+Data Format Negotiation
+=======================
+
+The SDR device uses the :ref:`format` ioctls to select the
+capture and output format. Both the sampling resolution and the data
+streaming format are bound to that selectable format. In addition to the
+basic :ref:`format` ioctls, the
+:ref:`VIDIOC_ENUM_FMT` ioctl must be supported as
+well.
+
+To use the :ref:`format` ioctls applications set the ``type``
+field of a struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_SDR_CAPTURE`` or ``V4L2_BUF_TYPE_SDR_OUTPUT`` and use
+the struct :c:type:`v4l2_sdr_format` ``sdr`` member
+of the ``fmt`` union as needed per the desired operation. Currently
+there is two fields, ``pixelformat`` and ``buffersize``, of struct
+struct :c:type:`v4l2_sdr_format` which are used.
+Content of the ``pixelformat`` is V4L2 FourCC code of the data format.
+The ``buffersize`` field is maximum buffer size in bytes required for
+data transfer, set by the driver in order to inform application.

+*************************
+Sliced VBI Data Interface
+*************************
+
+VBI stands for Vertical Blanking Interval, a gap in the sequence of
+lines of an analog video signal. During VBI no picture information is
+transmitted, allowing some time while the electron beam of a cathode ray
+tube TV returns to the top of the screen.
+
+Sliced VBI devices use hardware to demodulate data transmitted in the
+VBI. V4L2 drivers shall *not* do this by software, see also the
+:ref:`raw VBI interface <raw-vbi>`. The data is passed as short
+packets of fixed size, covering one scan line each. The number of
+packets per video frame is variable.
+
+Sliced VBI capture and output devices are accessed through the same
+character special files as raw VBI devices. When a driver supports both
+interfaces, the default function of a ``/dev/vbi`` device is *raw* VBI
+capturing or output, and the sliced VBI function is only available after
+calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl as defined
+below. Likewise a ``/dev/video`` device may support the sliced VBI API,
+however the default function here is video capturing or output.
+Different file descriptors must be used to pass raw and sliced VBI data
+simultaneously, if this is supported by the driver.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the sliced VBI capturing or output API set the
+``V4L2_CAP_SLICED_VBI_CAPTURE`` or ``V4L2_CAP_SLICED_VBI_OUTPUT`` flag
+respectively, in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
+read/write, streaming or asynchronous :ref:`I/O methods <io>` must be
+supported. Sliced VBI devices may have a tuner or modulator.
+
+
+Supplemental Functions
+======================
+
+Sliced VBI devices shall support :ref:`video input or output <video>`
+and :ref:`tuner or modulator <tuner>` ioctls if they have these
+capabilities, and they may support :ref:`control` ioctls.
+The :ref:`video standard <standard>` ioctls provide information vital
+to program a sliced VBI device, therefore must be supported.
+
+
+.. _sliced-vbi-format-negotitation:
+
+Sliced VBI Format Negotiation
+=============================
+
+To find out which data services are supported by the hardware
+applications can call the
+:ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl.
+All drivers implementing the sliced VBI interface must support this
+ioctl. The results may differ from those of the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl when the number of VBI
+lines the hardware can capture or output per frame, or the number of
+services it can identify on a given line are limited. For example on PAL
+line 16 the hardware may be able to look for a VPS or Teletext signal,
+but not both at the same time.
+
+To determine the currently selected services applications set the
+``type`` field of struct :c:type:`v4l2_format` to
+``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` or
+``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``, and the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl fills the ``fmt.sliced``
+member, a struct
+:c:type:`v4l2_sliced_vbi_format`.
+
+Applications can request different parameters by initializing or
+modifying the ``fmt.sliced`` member and calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with a pointer to the
+struct :c:type:`v4l2_format` structure.
+
+The sliced VBI API is more complicated than the raw VBI API because the
+hardware must be told which VBI service to expect on each scan line. Not
+all services may be supported by the hardware on all lines (this is
+especially true for VBI output where Teletext is often unsupported and
+other services can only be inserted in one specific line). In many
+cases, however, it is sufficient to just set the ``service_set`` field
+to the required services and let the driver fill the ``service_lines``
+array according to hardware capabilities. Only if more precise control
+is needed should the programmer set the ``service_lines`` array
+explicitly.
+
+The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl modifies the parameters
+according to hardware capabilities. When the driver allocates resources
+at this point, it may return an ``EBUSY`` error code if the required
+resources are temporarily unavailable. Other resource allocation points
+which may return ``EBUSY`` can be the
+:ref:`VIDIOC_STREAMON` ioctl and the first
+:ref:`read() <func-read>`, :ref:`write() <func-write>` and
+:ref:`select() <func-select>` call.

+Drivers may return an ``EINVAL`` error code when applications attempt to
+read or write data without prior format negotiation, after switching the
+video standard (which may invalidate the negotiated VBI parameters) and
+after switching the video input (which may change the video standard as
+a side effect). The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl may
+return an ``EBUSY`` error code when applications attempt to change the
+format while i/o is in progress (between a
+:ref:`VIDIOC_STREAMON` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` call, and after the first
+:ref:`read() <func-read>` or :ref:`write() <func-write>` call).
+
+
+Reading and writing sliced VBI data
+===================================
+
+A single :ref:`read() <func-read>` or :ref:`write() <func-write>`
+call must pass all data belonging to one video frame. That is an array
+of struct :c:type:`v4l2_sliced_vbi_data` structures with one or
+more elements and a total size not exceeding ``io_size`` bytes. Likewise
+in streaming I/O mode one buffer of ``io_size`` bytes must contain data
+of one video frame. The ``id`` of unused
+struct :c:type:`v4l2_sliced_vbi_data` elements must be zero.

+been negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When the line numbers are
+unknown the driver must pass the packets in transmitted order. The
+driver can insert empty packets with ``id`` set to zero anywhere in the
+packet array.
+
+To assure synchronization and to distinguish from frame dropping, when a
+captured frame does not carry any of the requested data services drivers
+must pass one or more empty packets. When an application fails to pass
+VBI data in time for output, the driver must output the last VPS and WSS
+packet again, and disable the output of Closed Caption and Teletext
+data, or output data which is ignored by Closed Caption and Teletext
+decoders.
+
+A sliced VBI device may support :ref:`read/write <rw>` and/or
+streaming (:ref:`memory mapping <mmap>` and/or
+:ref:`user pointer <userp>`) I/O. The latter bears the possibility of
+synchronizing video and VBI data by using buffer timestamps.
+
+
+Sliced VBI Data in MPEG Streams
+===============================
+
+If a device can produce an MPEG output stream, it may be capable of
+providing
+:ref:`negotiated sliced VBI services <sliced-vbi-format-negotitation>`
+as data embedded in the MPEG stream. Users or applications control this
+sliced VBI data insertion with the
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control.
+
+If the driver does not provide the
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control, or only allows that control to be set to
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`,
+then the device cannot embed sliced VBI data in the MPEG stream.
+
+The
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control does not implicitly set the device driver to capture nor cease
+capturing sliced VBI data. The control only indicates to embed sliced
+VBI data in the MPEG stream, if an application has negotiated sliced VBI
+service be captured.
+
+It may also be the case that a device can embed sliced VBI data in only
+certain types of MPEG streams: for example in an MPEG-2 PS but not an
+MPEG-2 TS. In this situation, if sliced VBI data insertion is requested,
+the sliced VBI data will be embedded in MPEG stream types when
+supported, and silently omitted from MPEG stream types where sliced VBI
+data insertion is not supported by the device.
+
+The following subsections specify the format of the embedded sliced VBI
+data.
+
+
+MPEG Stream Embedded, Sliced VBI Data Format: NONE
+--------------------------------------------------
+
+The
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`
+embedded sliced VBI format shall be interpreted by drivers as a control
+to cease embedding sliced VBI data in MPEG streams. Neither the device
+nor driver shall insert "empty" embedded sliced VBI data packets in the
+MPEG stream when this format is set. No MPEG stream data structures are
+specified for this format.
+
+
+MPEG Stream Embedded, Sliced VBI Data Format: IVTV
+--------------------------------------------------
+
+The
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
+embedded sliced VBI format, when supported, indicates to the driver to
+embed up to 36 lines of sliced VBI data per frame in an MPEG-2 *Private
+Stream 1 PES* packet encapsulated in an MPEG-2 *Program Pack* in the
+MPEG stream.
+
+*Historical context*: This format specification originates from a
+custom, embedded, sliced VBI data format used by the ``ivtv`` driver.
+This format has already been informally specified in the kernel sources
+in the file ``Documentation/media/v4l-drivers/cx2341x.rst`` . The
+maximum size of the payload and other aspects of this format are driven
+by the CX23415 MPEG decoder's capabilities and limitations with respect
+to extracting, decoding, and displaying sliced VBI data embedded within
+an MPEG stream.
+
+This format's use is *not* exclusive to the ``ivtv`` driver *nor*
+exclusive to CX2341x devices, as the sliced VBI data packet insertion
+into the MPEG stream is implemented in driver software. At least the
+``cx18`` driver provides sliced VBI data insertion into an MPEG-2 PS in
+this format as well.
+
+The following definitions specify the payload of the MPEG-2 *Private
+Stream 1 PES* packets that contain sliced VBI data when
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
+is set. (The MPEG-2 *Private Stream 1 PES* packet header and
+encapsulating MPEG-2 *Program Pack* header are not detailed here. Please
+refer to the MPEG-2 specifications for details on those packet headers.)
+
+The payload of the MPEG-2 *Private Stream 1 PES* packets that contain
+sliced VBI data is specified by struct
+:c:type:`v4l2_mpeg_vbi_fmt_ivtv`. The
+payload is variable length, depending on the actual number of lines of
+sliced VBI data present in a video frame. The payload may be padded at
+the end with unspecified fill bytes to align the end of the payload to a
+4-byte boundary. The payload shall never exceed 1552 bytes (2 fields
+with 18 lines/field with 43 bytes of data/line and a 4 byte magic
+number).

+********************
+Sub-device Interface
+********************
+
+The complex nature of V4L2 devices, where hardware is often made of
+several integrated circuits that need to interact with each other in a
+controlled way, leads to complex V4L2 drivers. The drivers usually
+reflect the hardware model in software, and model the different hardware
+components as software blocks called sub-devices.
+
+V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
+implements the media device API, they will automatically inherit from
+media entities. Applications will be able to enumerate the sub-devices
+and discover the hardware topology using the media entities, pads and
+links enumeration API.
+
+In addition to make sub-devices discoverable, drivers can also choose to
+make them directly configurable by applications. When both the
+sub-device driver and the V4L2 device driver support this, sub-devices
+will feature a character device node on which ioctls can be called to
+
+-  query, read and write sub-devices controls
+
+-  subscribe and unsubscribe to events and retrieve them
+
+-  negotiate image formats on individual pads
+
+Sub-device character device nodes, conventionally named
+``/dev/v4l-subdev*``, use major number 81.
+
+
+Controls
+========
+
+Most V4L2 controls are implemented by sub-device hardware. Drivers
+usually merge all controls and expose them through video device nodes.
+Applications can control all sub-devices through a single interface.
+
+Complex devices sometimes implement the same control in different pieces
+of hardware. This situation is common in embedded platforms, where both
+sensors and image processing hardware implement identical functions,
+such as contrast adjustment, white balance or faulty pixels correction.
+As the V4L2 controls API doesn't support several identical controls in a
+single device, all but one of the identical controls are hidden.
+
+Applications can access those hidden controls through the sub-device
+node with the V4L2 control API described in :ref:`control`. The ioctls
+behave identically as when issued on V4L2 device nodes, with the
+exception that they deal only with controls implemented in the
+sub-device.
+
+Depending on the driver, those controls might also be exposed through
+one (or several) V4L2 device nodes.
+
+
+Events
+======
+
+V4L2 sub-devices can notify applications of events as described in
+:ref:`event`. The API behaves identically as when used on V4L2 device
+nodes, with the exception that it only deals with events generated by
+the sub-device. Depending on the driver, those events might also be
+reported on one (or several) V4L2 device nodes.
+
+
+.. _pad-level-formats:
+
+Pad-level Formats
+=================
+
+.. warning::
+
+    Pad-level formats are only applicable to very complex devices that
+    need to expose low-level format configuration to user space. Generic
+    V4L2 applications do *not* need to use the API described in this
+    section.
+
+.. note::
+
+    For the purpose of this section, the term *format* means the
+    combination of media bus data format, frame width and frame height.
+
+Image formats are typically negotiated on video capture and output
+devices using the format and
+:ref:`selection <VIDIOC_SUBDEV_G_SELECTION>` ioctls. The driver is
+responsible for configuring every block in the video pipeline according
+to the requested format at the pipeline input and/or output.
+
+For complex devices, such as often found in embedded systems, identical
+image sizes at the output of a pipeline can be achieved using different
+hardware configurations. One such example is shown on
+:ref:`pipeline-scaling`, where image scaling can be performed on both
+the video sensor and the host image processing hardware.
+
+
+.. _pipeline-scaling:
+
+.. kernel-figure:: pipeline.dot
+    :alt:   pipeline.dot
+    :align: center
+
+    Image Format Negotiation on Pipelines
+
+    High quality and high speed pipeline configuration
+
+
+
+The sensor scaler is usually of less quality than the host scaler, but
+scaling on the sensor is required to achieve higher frame rates.
+Depending on the use case (quality vs. speed), the pipeline must be
+configured differently. Applications need to configure the formats at
+every point in the pipeline explicitly.
+
+Drivers that implement the :ref:`media API <media-controller-intro>`
+can expose pad-level image format configuration to applications. When
+they do, applications can use the
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls. to
+negotiate formats on a per-pad basis.
+
+Applications are responsible for configuring coherent parameters on the
+whole pipeline and making sure that connected pads have compatible
+formats. The pipeline is checked for formats mismatch at
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` time, and an ``EPIPE`` error
+code is then returned if the configuration is invalid.
+
+Pad-level image format configuration support can be tested by calling
+the :ref:`VIDIOC_SUBDEV_G_FMT` ioctl on pad
+0. If the driver returns an ``EINVAL`` error code pad-level format
+configuration is not supported by the sub-device.
+
+
+Format Negotiation
+------------------
+
+Acceptable formats on pads can (and usually do) depend on a number of
+external parameters, such as formats on other pads, active links, or
+even controls. Finding a combination of formats on all pads in a video
+pipeline, acceptable to both application and driver, can't rely on
+formats enumeration only. A format negotiation mechanism is required.
+
+Central to the format negotiation mechanism are the get/set format
+operations. When called with the ``which`` argument set to
+:ref:`V4L2_SUBDEV_FORMAT_TRY <VIDIOC_SUBDEV_G_FMT>`, the
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls operate on
+a set of formats parameters that are not connected to the hardware
+configuration. Modifying those 'try' formats leaves the device state
+untouched (this applies to both the software state stored in the driver
+and the hardware state stored in the device itself).
+
+While not kept as part of the device state, try formats are stored in
+the sub-device file handles. A
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` call will return
+the last try format set *on the same sub-device file handle*. Several
+applications querying the same sub-device at the same time will thus not
+interact with each other.
+
+To find out whether a particular format is supported by the device,
+applications use the
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl. Drivers
+verify and, if needed, change the requested ``format`` based on device
+requirements and return the possibly modified value. Applications can
+then choose to try a different format or accept the returned value and
+continue.
+
+Formats returned by the driver during a negotiation iteration are
+guaranteed to be supported by the device. In particular, drivers
+guarantee that a returned format will not be further changed if passed
+to an :ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` call as-is
+(as long as external parameters, such as formats on other pads or links'
+configuration are not changed).
+
+Drivers automatically propagate formats inside sub-devices. When a try
+or active format is set on a pad, corresponding formats on other pads of
+the same sub-device can be modified by the driver. Drivers are free to
+modify formats as required by the device. However, they should comply
+with the following rules when possible:
+
+-  Formats should be propagated from sink pads to source pads. Modifying
+   a format on a source pad should not modify the format on any sink
+   pad.
+
+-  Sub-devices that scale frames using variable scaling factors should
+   reset the scale factors to default values when sink pads formats are
+   modified. If the 1:1 scaling ratio is supported, this means that
+   source pads formats should be reset to the sink pads formats.
+
+Formats are not propagated across links, as that would involve
+propagating them from one sub-device file handle to another.
+Applications must then take care to configure both ends of every link
+explicitly with compatible formats. Identical formats on the two ends of
+a link are guaranteed to be compatible. Drivers are free to accept
+different formats matching device requirements as being compatible.

+1. Initial state. The sensor source pad format is set to its native 3MP
+   size and V4L2_MBUS_FMT_SGRBG8_1X8 media bus code. Formats on the
+   host frontend and scaler sink and source pads have the default
+   values, as well as the compose rectangle on the scaler's sink pad.
+
+2. The application configures the frontend sink pad format's size to
+   2048x1536 and its media bus code to V4L2_MBUS_FMT_SGRBG_1X8. The
+   driver propagates the format to the frontend source pad.
+
+3. The application configures the scaler sink pad format's size to
+   2046x1534 and the media bus code to V4L2_MBUS_FMT_SGRBG_1X8 to
+   match the frontend source size and media bus code. The media bus code
+   on the sink pad is set to V4L2_MBUS_FMT_SGRBG_1X8. The driver
+   propagates the size to the compose selection rectangle on the
+   scaler's sink pad, and the format to the scaler source pad.
+
+4. The application configures the size of the compose selection
+   rectangle of the scaler's sink pad 1280x960. The driver propagates
+   the size to the scaler's source pad format.
+
+When satisfied with the try results, applications can set the active
+formats by setting the ``which`` argument to
+``V4L2_SUBDEV_FORMAT_ACTIVE``. Active formats are changed exactly as try
+formats by drivers. To avoid modifying the hardware state during format
+negotiation, applications should negotiate try formats first and then
+modify the active settings using the try formats returned during the
+last negotiation iteration. This guarantees that the active format will
+be applied as-is by the driver without being modified.
+
+
+.. _v4l2-subdev-selections:
+
+Selections: cropping, scaling and composition
+---------------------------------------------
+
+Many sub-devices support cropping frames on their input or output pads
+(or possible even on both). Cropping is used to select the area of
+interest in an image, typically on an image sensor or a video decoder.
+It can also be used as part of digital zoom implementations to select
+the area of the image that will be scaled up.
+
+Crop settings are defined by a crop rectangle and represented in a
+struct :c:type:`v4l2_rect` by the coordinates of the top
+left corner and the rectangle size. Both the coordinates and sizes are
+expressed in pixels.
+
+As for pad formats, drivers store try and active rectangles for the
+selection targets :ref:`v4l2-selections-common`.
+
+On sink pads, cropping is applied relative to the current pad format.
+The pad format represents the image size as received by the sub-device
+from the previous block in the pipeline, and the crop rectangle
+represents the sub-image that will be transmitted further inside the
+sub-device for processing.
+
+The scaling operation changes the size of the image by scaling it to new
+dimensions. The scaling ratio isn't specified explicitly, but is implied
+from the original and scaled image sizes. Both sizes are represented by
+struct :c:type:`v4l2_rect`.
+
+Scaling support is optional. When supported by a subdev, the crop
+rectangle on the subdev's sink pad is scaled to the size configured
+using the
+:ref:`VIDIOC_SUBDEV_S_SELECTION <VIDIOC_SUBDEV_G_SELECTION>` IOCTL
+using ``V4L2_SEL_TGT_COMPOSE`` selection target on the same pad. If the
+subdev supports scaling but not composing, the top and left values are
+not used and must always be set to zero.
+
+On source pads, cropping is similar to sink pads, with the exception
+that the source size from which the cropping is performed, is the
+COMPOSE rectangle on the sink pad. In both sink and source pads, the
+crop rectangle must be entirely contained inside the source image size
+for the crop operation.
+
+The drivers should always use the closest possible rectangle the user
+requests on all selection targets, unless specifically told otherwise.
+``V4L2_SEL_FLAG_GE`` and ``V4L2_SEL_FLAG_LE`` flags may be used to round
+the image size either up or down. :ref:`v4l2-selection-flags`
+
+
+Types of selection targets
+--------------------------
+
+
+Actual targets
+^^^^^^^^^^^^^^
+
+Actual targets (without a postfix) reflect the actual hardware
+configuration at any point of time. There is a BOUNDS target
+corresponding to every actual target.
+
+
+BOUNDS targets
+^^^^^^^^^^^^^^
+
+BOUNDS targets is the smallest rectangle that contains all valid actual
+rectangles. It may not be possible to set the actual rectangle as large
+as the BOUNDS rectangle, however. This may be because e.g. a sensor's
+pixel array is not rectangular but cross-shaped or round. The maximum
+size may also be smaller than the BOUNDS rectangle.
+
+
+Order of configuration and format propagation
+---------------------------------------------
+
+Inside subdevs, the order of image processing steps will always be from
+the sink pad towards the source pad. This is also reflected in the order
+in which the configuration must be performed by the user: the changes
+made will be propagated to any subsequent stages. If this behaviour is
+not desired, the user must set ``V4L2_SEL_FLAG_KEEP_CONFIG`` flag. This
+flag causes no propagation of the changes are allowed in any
+circumstances. This may also cause the accessed rectangle to be adjusted
+by the driver, depending on the properties of the underlying hardware.
+
+The coordinates to a step always refer to the actual size of the
+previous step. The exception to this rule is the sink compose
+rectangle, which refers to the sink compose bounds rectangle --- if it
+is supported by the hardware.
+
+1. Sink pad format. The user configures the sink pad format. This format
+   defines the parameters of the image the entity receives through the
+   pad for further processing.
+
+2. Sink pad actual crop selection. The sink pad crop defines the crop
+   performed to the sink pad format.
+
+3. Sink pad actual compose selection. The size of the sink pad compose
+   rectangle defines the scaling ratio compared to the size of the sink
+   pad crop rectangle. The location of the compose rectangle specifies
+   the location of the actual sink compose rectangle in the sink compose
+   bounds rectangle.
+
+4. Source pad actual crop selection. Crop on the source pad defines crop
+   performed to the image in the sink compose bounds rectangle.
+
+5. Source pad format. The source pad format defines the output pixel
+   format of the subdev, as well as the other parameters with the
+   exception of the image width and height. Width and height are defined
+   by the size of the source pad actual crop selection.
+
+Accessing any of the above rectangles not supported by the subdev will
+return ``EINVAL``. Any rectangle referring to a previous unsupported
+rectangle coordinates will instead refer to the previous supported
+rectangle. For example, if sink crop is not supported, the compose
+selection will refer to the sink pad format dimensions instead.

+
+    **Figure 4.5. Image processing in subdevs: simple crop example**
+
+In the above example, the subdev supports cropping on its sink pad. To
+configure it, the user sets the media bus format on the subdev's sink
+pad. Now the actual crop rectangle can be set on the sink pad --- the
+location and size of this rectangle reflect the location and size of a
+rectangle to be cropped from the sink format. The size of the sink crop
+rectangle will also be the size of the format of the subdev's source
+pad.

+
+    **Figure 4.6. Image processing in subdevs: scaling with multiple sources**
+
+In this example, the subdev is capable of first cropping, then scaling
+and finally cropping for two source pads individually from the resulting
+scaled image. The location of the scaled image in the cropped image is
+ignored in sink compose target. Both of the locations of the source crop
+rectangles refer to the sink scaling rectangle, independently cropping
+an area at location specified by the source crop rectangle from it.

+
+    **Figure 4.7. Image processing in subdevs: scaling and composition with multiple sinks and sources**
+
+The subdev driver supports two sink pads and two source pads. The images
+from both of the sink pads are individually cropped, then scaled and
+further composed on the composition bounds rectangle. From that, two
+independent streams are cropped and sent out of the subdev from the
+source pads.

+Touch Devices

+
+Touch devices are accessed through character device special files named
+``/dev/v4l-touch0`` to ``/dev/v4l-touch255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+Overview
+========
+
+Sensors may be Optical, or Projected Capacitive touch (PCT).
+
+Processing is required to analyse the raw data and produce input events. In
+some systems, this may be performed on the ASIC and the raw data is purely a
+side-channel for diagnostics or tuning. In other systems, the ASIC is a simple
+analogue front end device which delivers touch data at high rate, and any touch
+processing must be done on the host.
+
+For capacitive touch sensing, the touchscreen is composed of an array of
+horizontal and vertical conductors (alternatively called rows/columns, X/Y
+lines, or tx/rx). Mutual Capacitance measured is at the nodes where the
+conductors cross. Alternatively, Self Capacitance measures the signal from each
+column and row independently.
+
+A touch input may be determined by comparing the raw capacitance measurement to
+a no-touch reference (or "baseline") measurement:
+
+Delta = Raw - Reference
+
+The reference measurement takes account of variations in the capacitance across
+the touch sensor matrix, for example manufacturing irregularities,
+environmental or edge effects.
+
+Querying Capabilities
+=====================
+
+Devices supporting the touch interface set the ``V4L2_CAP_VIDEO_CAPTURE`` flag
+and the ``V4L2_CAP_TOUCH`` flag in the ``capabilities`` field of
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+At least one of the read/write or streaming I/O methods must be
+supported.
+
+The formats supported by touch devices are documented in
+:ref:`Touch Formats <tch-formats>`.
+
+Data Format Negotiation
+=======================
+
+A touch device may support any I/O method.

+Differences between V4L and V4L2
+********************************
+
+The Video For Linux API was first introduced in Linux 2.1 to unify and
+replace various TV and radio device related interfaces, developed
+independently by driver writers in prior years. Starting with Linux 2.5
+the much improved V4L2 API replaces the V4L API. The support for the old
+V4L calls were removed from Kernel, but the library :ref:`libv4l`
+supports the conversion of a V4L API system call into a V4L2 one.
+
+
+Opening and Closing Devices
+===========================
+
+For compatibility reasons the character device file names recommended
+for V4L2 video capture, overlay, radio and raw vbi capture devices did
+not change from those used by V4L. They are listed in :ref:`devices`
+and below in :ref:`v4l-dev`.
+
+The teletext devices (minor range 192-223) have been removed in V4L2 and
+no longer exist. There is no hardware available anymore for handling
+pure teletext. Instead raw or sliced VBI is used.
+
+The V4L ``videodev`` module automatically assigns minor numbers to
+drivers in load order, depending on the registered device type. We
+recommend that V4L2 drivers by default register devices with the same
+numbers, but the system administrator can assign arbitrary minor numbers
+using driver module options. The major device number remains 81.

+
+V4L prohibits (or used to prohibit) multiple opens of a device file.
+V4L2 drivers *may* support multiple opens, see :ref:`open` for details
+and consequences.
+
+V4L drivers respond to V4L2 ioctls with an ``EINVAL`` error code.
+
+
+Querying Capabilities
+=====================
+
+The V4L ``VIDIOCGCAP`` ioctl is equivalent to V4L2's
+:ref:`VIDIOC_QUERYCAP`.
+
+The ``name`` field in struct ``video_capability`` became
+``card`` in struct :c:type:`v4l2_capability`, ``type``
+was replaced by ``capabilities``. Note V4L2 does not distinguish between
+device types like this, better think of basic video input, video output
+and radio devices supporting a set of related functions like video
+capturing, video overlay and VBI capturing. See :ref:`open` for an
+introduction.

+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl with the desired
+dimensions returns the closest size possible, taking into account the
+current video standard, cropping and scaling limitations.
+
+
+Video Sources
+=============
+
+V4L provides the ``VIDIOCGCHAN`` and ``VIDIOCSCHAN`` ioctl using struct
+``video_channel`` to enumerate the video inputs of a V4L
+device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_ENUMINPUT`,
+:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` using struct
+:c:type:`v4l2_input` as discussed in :ref:`video`.
+
+The ``channel`` field counting inputs was renamed to ``index``, the
+video input types were renamed as follows:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct ``video_channel`` ``type``
+      - struct :c:type:`v4l2_input` ``type``
+    * - ``VIDEO_TYPE_TV``
+      - ``V4L2_INPUT_TYPE_TUNER``
+    * - ``VIDEO_TYPE_CAMERA``
+      - ``V4L2_INPUT_TYPE_CAMERA``
+
+
+Unlike the ``tuners`` field expressing the number of tuners of this
+input, V4L2 assumes each video input is connected to at most one tuner.
+However a tuner can have more than one input, i. e. RF connectors, and a
+device can have multiple tuners. The index number of the tuner
+associated with the input, if any, is stored in field ``tuner`` of
+struct :c:type:`v4l2_input`. Enumeration of tuners is
+discussed in :ref:`tuner`.
+
+The redundant ``VIDEO_VC_TUNER`` flag was dropped. Video inputs
+associated with a tuner are of type ``V4L2_INPUT_TYPE_TUNER``. The
+``VIDEO_VC_AUDIO`` flag was replaced by the ``audioset`` field. V4L2
+considers devices with up to 32 audio inputs. Each set bit in the
+``audioset`` field represents one audio input this video input combines
+with. For information about audio inputs and how to switch between them
+see :ref:`audio`.
+
+The ``norm`` field describing the supported video standards was replaced
+by ``std``. The V4L specification mentions a flag ``VIDEO_VC_NORM``
+indicating whether the standard can be changed. This flag was a later
+addition together with the ``norm`` field and has been removed in the
+meantime. V4L2 has a similar, albeit more comprehensive approach to
+video standards, see :ref:`standard` for more information.
+
+
+Tuning
+======
+
+The V4L ``VIDIOCGTUNER`` and ``VIDIOCSTUNER`` ioctl and struct
+``video_tuner`` can be used to enumerate the tuners of a
+V4L TV or radio device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
+:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` using struct
+:c:type:`v4l2_tuner`. Tuners are covered in :ref:`tuner`.
+
+The ``tuner`` field counting tuners was renamed to ``index``. The fields
+``name``, ``rangelow`` and ``rangehigh`` remained unchanged.
+
+The ``VIDEO_TUNER_PAL``, ``VIDEO_TUNER_NTSC`` and ``VIDEO_TUNER_SECAM``
+flags indicating the supported video standards were dropped. This
+information is now contained in the associated struct
+:c:type:`v4l2_input`. No replacement exists for the
+``VIDEO_TUNER_NORM`` flag indicating whether the video standard can be
+switched. The ``mode`` field to select a different video standard was
+replaced by a whole new set of ioctls and structures described in
+:ref:`standard`. Due to its ubiquity it should be mentioned the BTTV
+driver supports several standards in addition to the regular
+``VIDEO_MODE_PAL`` (0), ``VIDEO_MODE_NTSC``, ``VIDEO_MODE_SECAM`` and
+``VIDEO_MODE_AUTO`` (3). Namely N/PAL Argentina, M/PAL, N/PAL, and NTSC
+Japan with numbers 3-6 (sic).
+
+The ``VIDEO_TUNER_STEREO_ON`` flag indicating stereo reception became
+``V4L2_TUNER_SUB_STEREO`` in field ``rxsubchans``. This field also
+permits the detection of monaural and bilingual audio, see the
+definition of struct :c:type:`v4l2_tuner` for details.
+Presently no replacement exists for the ``VIDEO_TUNER_RDS_ON`` and
+``VIDEO_TUNER_MBS_ON`` flags.
+
+The ``VIDEO_TUNER_LOW`` flag was renamed to ``V4L2_TUNER_CAP_LOW`` in
+the struct :c:type:`v4l2_tuner` ``capability`` field.
+
+The ``VIDIOCGFREQ`` and ``VIDIOCSFREQ`` ioctl to change the tuner
+frequency where renamed to
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`. They take a pointer
+to a struct :c:type:`v4l2_frequency` instead of an
+unsigned long integer.
+
+
+.. _v4l-image-properties:
+
+Image Properties
+================
+
+V4L2 has no equivalent of the ``VIDIOCGPICT`` and ``VIDIOCSPICT`` ioctl
+and struct ``video_picture``. The following fields where
+replaced by V4L2 controls accessible with the
+:ref:`VIDIOC_QUERYCTRL`,
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct ``video_picture``
+      - V4L2 Control ID
+    * - ``brightness``
+      - ``V4L2_CID_BRIGHTNESS``
+    * - ``hue``
+      - ``V4L2_CID_HUE``
+    * - ``colour``
+      - ``V4L2_CID_SATURATION``
+    * - ``contrast``
+      - ``V4L2_CID_CONTRAST``
+    * - ``whiteness``
+      - ``V4L2_CID_WHITENESS``
+
+
+The V4L picture controls are assumed to range from 0 to 65535 with no
+particular reset value. The V4L2 API permits arbitrary limits and
+defaults which can be queried with the
+:ref:`VIDIOC_QUERYCTRL` ioctl. For general
+information about controls see :ref:`control`.
+
+The ``depth`` (average number of bits per pixel) of a video image is
+implied by the selected image format. V4L2 does not explicitly provide
+such information assuming applications recognizing the format are aware
+of the image depth and others need not know. The ``palette`` field moved
+into the struct :c:type:`v4l2_pix_format`:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct ``video_picture`` ``palette``
+      - struct :c:type:`v4l2_pix_format` ``pixfmt``
+    * - ``VIDEO_PALETTE_GREY``
+      - :ref:`V4L2_PIX_FMT_GREY <V4L2-PIX-FMT-GREY>`
+    * - ``VIDEO_PALETTE_HI240``
+      - :ref:`V4L2_PIX_FMT_HI240 <pixfmt-reserved>` [#f3]_
+    * - ``VIDEO_PALETTE_RGB565``

+    * - ``VIDEO_PALETTE_YUV422P``
+      - :ref:`V4L2_PIX_FMT_YUV422P <V4L2-PIX-FMT-YUV422P>`
+    * - ``VIDEO_PALETTE_YUV411P``
+      - :ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>` [#f8]_
+    * - ``VIDEO_PALETTE_YUV420P``

+    * - ``VIDEO_PALETTE_YUV410P``
+      - :ref:`V4L2_PIX_FMT_YVU410 <V4L2-PIX-FMT-YVU410>`
+
+
+V4L2 image formats are defined in :ref:`pixfmt`. The image format can
+be selected with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Audio
+=====
+
+The ``VIDIOCGAUDIO`` and ``VIDIOCSAUDIO`` ioctl and struct
+``video_audio`` are used to enumerate the audio inputs
+of a V4L device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
+:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` using struct
+:c:type:`v4l2_audio` as discussed in :ref:`audio`.
+
+The ``audio`` "channel number" field counting audio inputs was renamed
+to ``index``.
+
+On ``VIDIOCSAUDIO`` the ``mode`` field selects *one* of the
+``VIDEO_SOUND_MONO``, ``VIDEO_SOUND_STEREO``, ``VIDEO_SOUND_LANG1`` or
+``VIDEO_SOUND_LANG2`` audio demodulation modes. When the current audio
+standard is BTSC ``VIDEO_SOUND_LANG2`` refers to SAP and
+``VIDEO_SOUND_LANG1`` is meaningless. Also undocumented in the V4L
+specification, there is no way to query the selected mode. On
+``VIDIOCGAUDIO`` the driver returns the *actually received* audio
+programmes in this field. In the V4L2 API this information is stored in
+the struct :c:type:`v4l2_tuner` ``rxsubchans`` and
+``audmode`` fields, respectively. See :ref:`tuner` for more
+information on tuners. Related to audio modes struct
+:c:type:`v4l2_audio` also reports if this is a mono or
+stereo input, regardless if the source is a tuner.
+
+The following fields where replaced by V4L2 controls accessible with the
+:ref:`VIDIOC_QUERYCTRL`,
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct ``video_audio``
+      - V4L2 Control ID
+    * - ``volume``
+      - ``V4L2_CID_AUDIO_VOLUME``
+    * - ``bass``
+      - ``V4L2_CID_AUDIO_BASS``
+    * - ``treble``
+      - ``V4L2_CID_AUDIO_TREBLE``
+    * - ``balance``
+      - ``V4L2_CID_AUDIO_BALANCE``
+
+
+To determine which of these controls are supported by a driver V4L
+provides the ``flags`` ``VIDEO_AUDIO_VOLUME``, ``VIDEO_AUDIO_BASS``,
+``VIDEO_AUDIO_TREBLE`` and ``VIDEO_AUDIO_BALANCE``. In the V4L2 API the
+:ref:`VIDIOC_QUERYCTRL` ioctl reports if the
+respective control is supported. Accordingly the ``VIDEO_AUDIO_MUTABLE``
+and ``VIDEO_AUDIO_MUTE`` flags where replaced by the boolean
+``V4L2_CID_AUDIO_MUTE`` control.
+
+All V4L2 controls have a ``step`` attribute replacing the struct
+``video_audio`` ``step`` field. The V4L audio controls
+are assumed to range from 0 to 65535 with no particular reset value. The
+V4L2 API permits arbitrary limits and defaults which can be queried with
+the :ref:`VIDIOC_QUERYCTRL` ioctl. For general
+information about controls see :ref:`control`.
+
+
+Frame Buffer Overlay
+====================
+
+The V4L2 ioctls equivalent to ``VIDIOCGFBUF`` and ``VIDIOCSFBUF`` are
+:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
+:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The ``base`` field of struct
+``video_buffer`` remained unchanged, except V4L2 defines
+a flag to indicate non-destructive overlays instead of a ``NULL``
+pointer. All other fields moved into the struct
+:c:type:`v4l2_pix_format` ``fmt`` substructure of
+struct :c:type:`v4l2_framebuffer`. The ``depth``
+field was replaced by ``pixelformat``. See :ref:`pixfmt-rgb` for a
+list of RGB formats and their respective color depths.
+
+Instead of the special ioctls ``VIDIOCGWIN`` and ``VIDIOCSWIN`` V4L2
+uses the general-purpose data format negotiation ioctls
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
+:c:type:`v4l2_format` as argument. Here the ``win`` member
+of the ``fmt`` union is used, a struct
+:c:type:`v4l2_window`.
+
+The ``x``, ``y``, ``width`` and ``height`` fields of struct
+``video_window`` moved into struct
+:c:type:`v4l2_rect` substructure ``w`` of struct
+:c:type:`v4l2_window`. The ``chromakey``, ``clips``, and
+``clipcount`` fields remained unchanged. Struct
+``video_clip`` was renamed to struct
+:c:type:`v4l2_clip`, also containing a struct
+:c:type:`v4l2_rect`, but the semantics are still the same.
+
+The ``VIDEO_WINDOW_INTERLACE`` flag was dropped. Instead applications
+must set the ``field`` field to ``V4L2_FIELD_ANY`` or
+``V4L2_FIELD_INTERLACED``. The ``VIDEO_WINDOW_CHROMAKEY`` flag moved
+into struct :c:type:`v4l2_framebuffer`, under the new
+name ``V4L2_FBUF_FLAG_CHROMAKEY``.
+
+In V4L, storing a bitmap pointer in ``clips`` and setting ``clipcount``
+to ``VIDEO_CLIP_BITMAP`` (-1) requests bitmap clipping, using a fixed
+size bitmap of 1024 × 625 bits. Struct :c:type:`v4l2_window`
+has a separate ``bitmap`` pointer field for this purpose and the bitmap
+size is determined by ``w.width`` and ``w.height``.
+
+The ``VIDIOCCAPTURE`` ioctl to enable or disable overlay was renamed to
+:ref:`VIDIOC_OVERLAY`.
+
+
+Cropping
+========
+
+To capture only a subsection of the full picture V4L defines the
+``VIDIOCGCAPTURE`` and ``VIDIOCSCAPTURE`` ioctls using struct
+``video_capture``. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` using struct
+:c:type:`v4l2_crop`, and the related
+:ref:`VIDIOC_CROPCAP` ioctl. This is a rather
+complex matter, see :ref:`crop` for details.
+
+The ``x``, ``y``, ``width`` and ``height`` fields moved into struct
+:c:type:`v4l2_rect` substructure ``c`` of struct
+:c:type:`v4l2_crop`. The ``decimation`` field was dropped. In
+the V4L2 API the scaling factor is implied by the size of the cropping
+rectangle and the size of the captured or overlaid image.
+
+The ``VIDEO_CAPTURE_ODD`` and ``VIDEO_CAPTURE_EVEN`` flags to capture
+only the odd or even field, respectively, were replaced by
+``V4L2_FIELD_TOP`` and ``V4L2_FIELD_BOTTOM`` in the field named
+``field`` of struct :c:type:`v4l2_pix_format` and
+struct :c:type:`v4l2_window`. These structures are used to
+select a capture or overlay format with the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Reading Images, Memory Mapping
+==============================
+
+
+Capturing using the read method
+-------------------------------
+
+There is no essential difference between reading images from a V4L or
+V4L2 device using the :ref:`read() <func-read>` function, however V4L2
+drivers are not required to support this I/O method. Applications can
+determine if the function is available with the
+:ref:`VIDIOC_QUERYCAP` ioctl. All V4L2 devices
+exchanging data with applications must support the
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions.
+
+To select an image format and size, V4L provides the ``VIDIOCSPICT`` and
+``VIDIOCSWIN`` ioctls. V4L2 uses the general-purpose data format
+negotiation ioctls :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
+:c:type:`v4l2_format` as argument, here the struct
+:c:type:`v4l2_pix_format` named ``pix`` of its
+``fmt`` union is used.
+
+For more information about the V4L2 read interface see :ref:`rw`.
+
+
+Capturing using memory mapping
+------------------------------
+
+Applications can read from V4L devices by mapping buffers in device
+memory, or more often just buffers allocated in DMA-able system memory,
+into their address space. This avoids the data copying overhead of the
+read method. V4L2 supports memory mapping as well, with a few
+differences.
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - V4L
+      - V4L2
+    * -
+      - The image format must be selected before buffers are allocated,
+	with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When no
+	format is selected the driver may use the last, possibly by
+	another application requested format.
+    * - Applications cannot change the number of buffers. The it is built
+	into the driver, unless it has a module option to change the
+	number when the driver module is loaded.
+      - The :ref:`VIDIOC_REQBUFS` ioctl allocates the
+	desired number of buffers, this is a required step in the
+	initialization sequence.
+    * - Drivers map all buffers as one contiguous range of memory. The
+	``VIDIOCGMBUF`` ioctl is available to query the number of buffers,
+	the offset of each buffer from the start of the virtual file, and
+	the overall amount of memory used, which can be used as arguments
+	for the :ref:`mmap() <func-mmap>` function.
+      - Buffers are individually mapped. The offset and size of each
+	buffer can be determined with the
+	:ref:`VIDIOC_QUERYBUF` ioctl.
+    * - The ``VIDIOCMCAPTURE`` ioctl prepares a buffer for capturing. It
+	also determines the image format for this buffer. The ioctl
+	returns immediately, eventually with an ``EAGAIN`` error code if no
+	video signal had been detected. When the driver supports more than
+	one buffer applications can call the ioctl multiple times and thus
+	have multiple outstanding capture requests.
+
+	The ``VIDIOCSYNC`` ioctl suspends execution until a particular
+	buffer has been filled.
+      - Drivers maintain an incoming and outgoing queue.
+	:ref:`VIDIOC_QBUF` enqueues any empty buffer into
+	the incoming queue. Filled buffers are dequeued from the outgoing
+	queue with the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. To wait
+	until filled buffers become available this function,
+	:ref:`select() <func-select>` or :ref:`poll() <func-poll>` can
+	be used. The :ref:`VIDIOC_STREAMON` ioctl
+	must be called once after enqueuing one or more buffers to start
+	capturing. Its counterpart
+	:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` stops capturing and
+	dequeues all buffers from both queues. Applications can query the
+	signal status, if known, with the
+	:ref:`VIDIOC_ENUMINPUT` ioctl.
+
+
+For a more in-depth discussion of memory mapping and examples, see
+:ref:`mmap`.
+
+
+Reading Raw VBI Data
+====================
+
+Originally the V4L API did not specify a raw VBI capture interface, only
+the device file ``/dev/vbi`` was reserved for this purpose. The only
+driver supporting this interface was the BTTV driver, de-facto defining
+the V4L VBI interface. Reading from the device yields a raw VBI image
+with the following parameters:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+    * - struct :c:type:`v4l2_vbi_format`
+      - V4L, BTTV driver
+    * - sampling_rate
+      - 28636363 Hz NTSC (or any other 525-line standard); 35468950 Hz PAL
+	and SECAM (625-line standards)
+    * - offset
+      - ?
+    * - samples_per_line
+      - 2048
+    * - sample_format
+      - V4L2_PIX_FMT_GREY. The last four bytes (a machine endianness
+	integer) contain a frame counter.
+    * - start[]
+      - 10, 273 NTSC; 22, 335 PAL and SECAM
+    * - count[]
+      - 16, 16 [#f9]_
+    * - flags
+      - 0
+
+
+Undocumented in the V4L specification, in Linux 2.3 the
+``VIDIOCGVBIFMT`` and ``VIDIOCSVBIFMT`` ioctls using struct
+``vbi_format`` were added to determine the VBI image
+parameters. These ioctls are only partially compatible with the V4L2 VBI
+interface specified in :ref:`raw-vbi`.
+
+An ``offset`` field does not exist, ``sample_format`` is supposed to be
+``VIDEO_PALETTE_RAW``, equivalent to ``V4L2_PIX_FMT_GREY``. The
+remaining fields are probably equivalent to struct
+:c:type:`v4l2_vbi_format`.
+
+Apparently only the Zoran (ZR 36120) driver implements these ioctls. The
+semantics differ from those specified for V4L2 in two ways. The
+parameters are reset on :ref:`open() <func-open>` and
+``VIDIOCSVBIFMT`` always returns an ``EINVAL`` error code if the parameters
+are invalid.
+
+
+Miscellaneous
+=============
+
+V4L2 has no equivalent of the ``VIDIOCGUNIT`` ioctl. Applications can
+find the VBI device associated with a video capture device (or vice
+versa) by reopening the device and requesting VBI data. For details see
+:ref:`open`.
+
+No replacement exists for ``VIDIOCKEY``, and the V4L functions for
+microcode programming. A new interface for MPEG compression and playback
+devices is documented in :ref:`extended-controls`.
+
+.. [#f1]
+   According to Documentation/admin-guide/devices.rst these should be symbolic links
+   to ``/dev/video0``. Note the original bttv interface is not
+   compatible with V4L or V4L2.
+
+.. [#f2]
+   According to ``Documentation/admin-guide/devices.rst`` a symbolic link to
+   ``/dev/radio0``.
+
+.. [#f3]
+   This is a custom format used by the BTTV driver, not one of the V4L2
+   standard formats.
+
+.. [#f4]
+   Presumably all V4L RGB formats are little-endian, although some
+   drivers might interpret them according to machine endianness. V4L2
+   defines little-endian, big-endian and red/blue swapped variants. For
+   details see :ref:`pixfmt-rgb`.
+
+.. [#f5]
+   ``VIDEO_PALETTE_YUV422`` and ``VIDEO_PALETTE_YUYV`` are the same
+   formats. Some V4L drivers respond to one, some to the other.
+
+.. [#f6]
+   Not to be confused with ``V4L2_PIX_FMT_YUV411P``, which is a planar
+   format.
+
+.. [#f7]
+   V4L explains this as: "RAW capture (BT848)"
+
+.. [#f8]
+   Not to be confused with ``V4L2_PIX_FMT_Y41P``, which is a packed
+   format.
+
+.. [#f9]
+   Old driver versions used different values, eventually the custom
+   ``BTTV_VBISIZE`` ioctl was added to query the correct values.

+************************************
+
+The DMABUF framework provides a generic method for sharing buffers
+between multiple devices. Device drivers that support DMABUF can export
+a DMA buffer to userspace as a file descriptor (known as the exporter
+role), import a DMA buffer from userspace using a file descriptor
+previously exported for a different or the same device (known as the
+importer role), or both. This section describes the DMABUF importer role
+API in V4L2.
+
+Refer to :ref:`DMABUF exporting <VIDIOC_EXPBUF>` for details about
+exporting V4L2 buffers as DMABUF file descriptors.
+
+Input and output devices support the streaming I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>` ioctl is set. Whether
+importing DMA buffers through DMABUF file descriptors is supported is
+determined by calling the :ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
+ioctl with the memory type set to ``V4L2_MEMORY_DMABUF``.
+
+This I/O method is dedicated to sharing DMA buffers between different
+devices, which may be V4L devices or other video-related devices (e.g.
+DRM). Buffers (planes) are allocated by a driver on behalf of an
+application. Next, these buffers are exported to the application as file
+descriptors using an API which is specific for an allocator driver. Only
+such file descriptor are exchanged. The descriptors and meta-information
+are passed in struct :c:type:`v4l2_buffer` (or in struct
+:c:type:`v4l2_plane` in the multi-planar API case). The
+driver must be switched into DMABUF I/O mode by calling the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>` with the desired buffer type.
+
+
+Example: Initiating streaming I/O with DMABUF file descriptors
+==============================================================
+
+.. code-block:: c
+
+    struct v4l2_requestbuffers reqbuf;
+
+    memset(&reqbuf, 0, sizeof (reqbuf));
+    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+    reqbuf.memory = V4L2_MEMORY_DMABUF;
+    reqbuf.count = 1;
+
+    if (ioctl(fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
+	if (errno == EINVAL)
+	    printf("Video capturing or DMABUF streaming is not supported\\n");
+	else
+	    perror("VIDIOC_REQBUFS");
+
+	exit(EXIT_FAILURE);
+    }
+
+The buffer (plane) file descriptor is passed on the fly with the
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. In case of multiplanar
+buffers, every plane can be associated with a different DMABUF
+descriptor. Although buffers are commonly cycled, applications can pass
+a different DMABUF descriptor at each :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call.
+
+Example: Queueing DMABUF using single plane API
+===============================================
+
+.. code-block:: c
+
+    int buffer_queue(int v4lfd, int index, int dmafd)
+    {
+	struct v4l2_buffer buf;
+
+	memset(&buf, 0, sizeof buf);
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	buf.memory = V4L2_MEMORY_DMABUF;
+	buf.index = index;
+	buf.m.fd = dmafd;
+
+	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
+	    perror("VIDIOC_QBUF");
+	    return -1;
+	}
+
+	return 0;
+    }
+
+Example 3.6. Queueing DMABUF using multi plane API
+==================================================
+
+.. code-block:: c
+
+    int buffer_queue_mp(int v4lfd, int index, int dmafd[], int n_planes)
+    {
+	struct v4l2_buffer buf;
+	struct v4l2_plane planes[VIDEO_MAX_PLANES];
+	int i;
+
+	memset(&buf, 0, sizeof buf);
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
+	buf.memory = V4L2_MEMORY_DMABUF;
+	buf.index = index;
+	buf.m.planes = planes;
+	buf.length = n_planes;
+
+	memset(&planes, 0, sizeof planes);
+
+	for (i = 0; i < n_planes; ++i)
+	    buf.m.planes[i].m.fd = dmafd[i];
+
+	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
+	    perror("VIDIOC_QBUF");
+	    return -1;
+	}
+
+	return 0;
+    }
+
+Captured or displayed buffers are dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
+buffer at any time between the completion of the DMA and this ioctl. The
+memory is also unlocked when
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, or when the device is closed.
+
+For capturing applications it is customary to enqueue a number of empty
+buffers, to start capturing and enter the read loop. Here the
+application waits until a filled buffer can be dequeued, and re-enqueues
+the buffer when the data is no longer needed. Output applications fill
+and enqueue buffers, when enough buffers are stacked up output is
+started. In the write loop, when the application runs out of free
+buffers it must wait until an empty buffer can be dequeued and reused.
+Two methods exist to suspend execution of the application until one or
+more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
+``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions are always available.
+
+To start and stop capturing or displaying applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls.
+
+.. note::
+
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
+   both queues and unlocks all buffers as a side effect. Since there is no
+   notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
+   outputted buffers.
+
+Drivers implementing DMABUF importing I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON
+<VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls,
+and the :ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions.

+Digital Video (DV) Timings
+**************************
+
+The video standards discussed so far have been dealing with Analog TV
+and the corresponding video timings. Today there are many more different
+hardware interfaces such as High Definition TV interfaces (HDMI), VGA,
+DVI connectors etc., that carry video signals and there is a need to
+extend the API to select the video timings for these interfaces. Since
+it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>`
+due to the limited bits available, a new set of ioctls was added to
+set/get video timings at the input and output.
+
+These ioctls deal with the detailed digital video timings that define
+each video format. This includes parameters such as the active video
+width and height, signal polarities, frontporches, backporches, sync
+widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get
+the timings of the formats in the :ref:`cea861` and :ref:`vesadmt`
+standards.
+
+To enumerate and query the attributes of the DV timings supported by a
+device applications use the
+:ref:`VIDIOC_ENUM_DV_TIMINGS` and
+:ref:`VIDIOC_DV_TIMINGS_CAP` ioctls. To set
+DV timings for the device applications use the
+:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get
+current DV timings they use the
+:ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. To detect
+the DV timings as seen by the video receiver applications use the
+:ref:`VIDIOC_QUERY_DV_TIMINGS` ioctl.
+
+Applications can make use of the :ref:`input-capabilities` and
+:ref:`output-capabilities` flags to determine whether the digital
+video ioctls can be used with the given input or output.

+enum v4l2_exposure_auto_type -
+    Enables automatic adjustments of the exposure time and/or iris
+    aperture. The effect of manual changes of the exposure time or iris
+    aperture while these features are enabled is undefined, drivers
+    should ignore such requests. Possible values are:

+      - Auto exposure time, manual iris.
+
+
+
+``V4L2_CID_EXPOSURE_ABSOLUTE (integer)``
+    Determines the exposure time of the camera sensor. The exposure time
+    is limited by the frame interval. Drivers should interpret the
+    values as 100 µs units, where the value 1 stands for 1/10000th of a
+    second, 10000 for 1 second and 100000 for 10 seconds.
+
+``V4L2_CID_EXPOSURE_AUTO_PRIORITY (boolean)``
+    When ``V4L2_CID_EXPOSURE_AUTO`` is set to ``AUTO`` or
+    ``APERTURE_PRIORITY``, this control determines if the device may
+    dynamically vary the frame rate. By default this feature is disabled

+
+``V4L2_CID_AUTO_EXPOSURE_BIAS (integer menu)``
+    Determines the automatic exposure compensation, it is effective only
+    when ``V4L2_CID_EXPOSURE_AUTO`` control is set to ``AUTO``,
+    ``SHUTTER_PRIORITY`` or ``APERTURE_PRIORITY``. It is expressed in
+    terms of EV, drivers should interpret the values as 0.001 EV units,
+    where the value 1000 stands for +1 EV.
+
+    Increasing the exposure compensation value is equivalent to
+    decreasing the exposure value (EV) and will increase the amount of
+    light at the image sensor. The camera performs the exposure
+    compensation by adjusting absolute exposure time and/or aperture.

+
+``V4L2_CID_ZOOM_CONTINUOUS (integer)``
+    Move the objective lens group at the specified speed until it
+    reaches physical device limits or until an explicit request to stop
+    the movement. A positive value moves the zoom lens group towards the
+    telephoto direction. A value of zero stops the zoom lens group
+    movement. A negative value moves the zoom lens group towards the

+
+``V4L2_CID_IRIS_ABSOLUTE (integer)``
+    This control sets the camera's aperture to the specified value. The

+
+``V4L2_CID_IRIS_RELATIVE (integer)``
+    This control modifies the camera's aperture by the specified amount.
+    The unit is undefined. Positive values open the iris one step
+    further, negative values close it one step further. This is a
+    write-only control.
+
+``V4L2_CID_PRIVACY (boolean)``
+    Prevent video from being acquired by the camera. When this control
+    is set to ``TRUE`` (1), no image can be captured by the camera.
+    Common means to enforce privacy are mechanical obturation of the
+    sensor and firmware image processing, but the device is not
+    restricted to these methods. Devices that implement the privacy
+    control must support read access and may support write access.
+
+``V4L2_CID_BAND_STOP_FILTER (integer)``
+    Switch the band-stop filter of a camera sensor on or off, or specify
+    its strength. Such band-stop filters can be used, for example, to
+    filter out the fluorescent light component.

+
+.. _v4l2-image-stabilization:
+
+``V4L2_CID_IMAGE_STABILIZATION (boolean)``
+    Enables or disables image stabilization.
+
+``V4L2_CID_ISO_SENSITIVITY (integer menu)``
+    Determines ISO equivalent of an image sensor indicating the sensor's
+    sensitivity to light. The numbers are expressed in arithmetic scale,
+    as per :ref:`iso12232` standard, where doubling the sensor
+    sensitivity is represented by doubling the numerical ISO value.
+    Applications should interpret the values as standard ISO values
+    multiplied by 1000, e.g. control value 800 stands for ISO 0.8.
+    Drivers will usually support only a subset of standard ISO values.
+    The effect of setting this control while the
+    ``V4L2_CID_ISO_SENSITIVITY_AUTO`` control is set to a value other

+    (enum)
+
+enum v4l2_scene_mode -
+    This control allows to select scene programs as the camera automatic
+    modes optimized for common shooting scenes. Within these modes the
+    camera determines best exposure, aperture, focusing, light metering,
+    white balance and equivalent sensitivity. The controls of those
+    parameters are influenced by the scene mode control. An exact
+    behavior in each mode is subject to the camera specification.
+
+    When the scene mode feature is not used, this control should be set
+    to ``V4L2_SCENE_MODE_NONE`` to make sure the other possibly related
+    controls are accessible. The following scene programs are defined:

+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_SCENE_MODE_NONE``
+      - The scene mode feature is disabled.
+    * - ``V4L2_SCENE_MODE_BACKLIGHT``
+      - Backlight. Compensates for dark shadows when light is coming from
+	behind a subject, also by automatically turning on the flash.
+    * - ``V4L2_SCENE_MODE_BEACH_SNOW``
+      - Beach and snow. This mode compensates for all-white or bright
+	scenes, which tend to look gray and low contrast, when camera's
+	automatic exposure is based on an average scene brightness. To
+	compensate, this mode automatically slightly overexposes the
+	frames. The white balance may also be adjusted to compensate for
+	the fact that reflected snow looks bluish rather than white.
+    * - ``V4L2_SCENE_MODE_CANDLELIGHT``
+      - Candle light. The camera generally raises the ISO sensitivity and
+	lowers the shutter speed. This mode compensates for relatively
+	close subject in the scene. The flash is disabled in order to
+	preserve the ambiance of the light.
+    * - ``V4L2_SCENE_MODE_DAWN_DUSK``
+      - Dawn and dusk. Preserves the colors seen in low natural light
+	before dusk and after down. The camera may turn off the flash, and
+	automatically focus at infinity. It will usually boost saturation
+	and lower the shutter speed.
+    * - ``V4L2_SCENE_MODE_FALL_COLORS``
+      - Fall colors. Increases saturation and adjusts white balance for
+	color enhancement. Pictures of autumn leaves get saturated reds
+	and yellows.
+    * - ``V4L2_SCENE_MODE_FIREWORKS``
+      - Fireworks. Long exposure times are used to capture the expanding
+	burst of light from a firework. The camera may invoke image
+	stabilization.
+    * - ``V4L2_SCENE_MODE_LANDSCAPE``
+      - Landscape. The camera may choose a small aperture to provide deep
+	depth of field and long exposure duration to help capture detail
+	in dim light conditions. The focus is fixed at infinity. Suitable
+	for distant and wide scenery.
+    * - ``V4L2_SCENE_MODE_NIGHT``
+      - Night, also known as Night Landscape. Designed for low light
+	conditions, it preserves detail in the dark areas without blowing
+	out bright objects. The camera generally sets itself to a
+	medium-to-high ISO sensitivity, with a relatively long exposure
+	time, and turns flash off. As such, there will be increased image
+	noise and the possibility of blurred image.
+    * - ``V4L2_SCENE_MODE_PARTY_INDOOR``
+      - Party and indoor. Designed to capture indoor scenes that are lit
+	by indoor background lighting as well as the flash. The camera
+	usually increases ISO sensitivity, and adjusts exposure for the
+	low light conditions.
+    * - ``V4L2_SCENE_MODE_PORTRAIT``
+      - Portrait. The camera adjusts the aperture so that the depth of
+	field is reduced, which helps to isolate the subject against a
+	smooth background. Most cameras recognize the presence of faces in
+	the scene and focus on them. The color hue is adjusted to enhance
+	skin tones. The intensity of the flash is often reduced.
+    * - ``V4L2_SCENE_MODE_SPORTS``
+      - Sports. Significantly increases ISO and uses a fast shutter speed
+	to freeze motion of rapidly-moving subjects. Increased image noise
+	may be seen in this mode.
+    * - ``V4L2_SCENE_MODE_SUNSET``
+      - Sunset. Preserves deep hues seen in sunsets and sunrises. It bumps
+	up the saturation.
+    * - ``V4L2_SCENE_MODE_TEXT``
+      - Text. It applies extra contrast and sharpness, it is typically a
+	black-and-white mode optimized for readability. Automatic focus
+	may be switched to close-up mode and this setting may also involve
+	some lens-distortion correction.

+
+``V4L2_CID_3A_LOCK (bitmask)``
+    This control locks or unlocks the automatic focus, exposure and
+    white balance. The automatic adjustments can be paused independently
+    by setting the corresponding lock bit to 1. The camera then retains
+    the settings until the lock bit is cleared. The following lock bits
+    are defined:
+
+    When a given algorithm is not enabled, drivers should ignore
+    requests to lock it and should return no error. An example might be
+    an application setting bit ``V4L2_LOCK_WHITE_BALANCE`` when the
+    ``V4L2_CID_AUTO_WHITE_BALANCE`` control is set to ``FALSE``. The
+    value of this control may be changed by exposure, white balance or

+
+``V4L2_CID_PAN_SPEED (integer)``
+    This control turns the camera horizontally at the specific speed.
+    The unit is undefined. A positive value moves the camera to the
+    right (clockwise when viewed from above), a negative value to the
+    left. A value of zero stops the motion if one is in progress and has
+    no effect otherwise.
+
+``V4L2_CID_TILT_SPEED (integer)``
+    This control turns the camera vertically at the specified speed. The
+    unit is undefined. A positive value moves the camera up, a negative
+    value down. A value of zero stops the motion if one is in progress
+    and has no effect otherwise.
+
+.. [#f1]
+   This control may be changed to a menu control in the future, if more
+   options are required.

+
+.. note::
+
+   These controls are applicable to all codecs and not just MPEG. The
+   defines are prefixed with V4L2_CID_MPEG/V4L2_MPEG as the controls

+
+MFC 5.1 Control IDs
+-------------------
+
+``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY_ENABLE (boolean)``
+    If the display delay is enabled then the decoder is forced to return
+    a CAPTURE buffer (decoded frame) after processing a certain number
+    of OUTPUT buffers. The delay can be set through
+    ``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY``. This
+    feature can be used for example for generating thumbnails of videos.
+    Applicable to the H264 decoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_DECODER_H264_DISPLAY_DELAY (integer)``
+    Display delay value for H264 decoder. The decoder is forced to
+    return a decoded frame after the set 'display delay' number of
+    frames. If this number is low it may result in frames returned out
+    of display order, in addition the hardware may still be using the
+    returned buffer as a reference picture for subsequent frames.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_NUM_REF_PIC_FOR_P (integer)``
+    The number of reference pictures used for encoding a P picture.
+    Applicable to the H264 encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_PADDING (boolean)``
+    Padding enable in the encoder - use a color instead of repeating
+    border pixels. Applicable to encoders.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_PADDING_YUV (integer)``
+    Padding color in the encoder. Applicable to encoders. The supplied
+    32-bit integer is interpreted as follows (bit 0 = least significant
+    bit):

+    Reaction coefficient for MFC rate control. Applicable to encoders.
+
+    .. note::
+
+       #. Valid only when the frame level RC is enabled.
+
+       #. For tight CBR, this field must be small (ex. 2 ~ 10). For
+	  VBR, this field must be large (ex. 100 ~ 1000).
+
+       #. It is not recommended to use the greater number than
+	  FRAME_RATE * (10^9 / BIT_RATE).
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_DARK (boolean)``
+    Adaptive rate control for dark region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_SMOOTH (boolean)``
+    Adaptive rate control for smooth region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_STATIC (boolean)``
+    Adaptive rate control for static region. Valid only when H.264 and
+    macroblock level RC is enabled
+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+``V4L2_CID_MPEG_MFC51_VIDEO_H264_ADAPTIVE_RC_ACTIVITY (boolean)``

+    (``V4L2_CID_MPEG_VIDEO_MB_RC_ENABLE``). Applicable to the H264
+    encoder.
+
+.. _v4l2-mpeg-mfc51-video-frame-skip-mode:
+
+``V4L2_CID_MPEG_MFC51_VIDEO_FRAME_SKIP_MODE``
+    (enum)
+
+enum v4l2_mpeg_mfc51_video_frame_skip_mode -
+    Indicates in what conditions the encoder should skip frames. If
+    encoding a frame would cause the encoded stream to be larger then a
+    chosen data limit then the frame will be skipped. Possible values
+    are:
+

+
+.. raw:: latex
+
+    \normalsize
+
+``V4L2_CID_MPEG_MFC51_VIDEO_RC_FIXED_TARGET_BIT (integer)``
+    Enable rate-control with fixed target bit. If this setting is
+    enabled, then the rate control logic of the encoder will calculate
+    the average bitrate for a GOP and keep it below or equal the set
+    bitrate target. Otherwise the rate control logic calculates the
+    overall average bitrate for the stream and keeps it below or equal
+    to the set bitrate. In the first case the average bitrate for the
+    whole stream will be smaller then the set bitrate. This is caused
+    because the average is calculated for smaller number of frames, on
+    the other hand enabling this setting will ensure that the stream
+    will meet tight bandwidth constraints. Applicable to encoders.

+*******************************
+Digital Video Control Reference
+*******************************
+
+The Digital Video control class is intended to control receivers and
+transmitters for `VGA <http://en.wikipedia.org/wiki/Vga>`__,
+`DVI <http://en.wikipedia.org/wiki/Digital_Visual_Interface>`__
+(Digital Visual Interface), HDMI (:ref:`hdmi`) and DisplayPort
+(:ref:`dp`). These controls are generally expected to be private to
+the receiver or transmitter subdevice that implements them, so they are
+only exposed on the ``/dev/v4l-subdev*`` device node.
+
+.. note::
+
+   Note that these devices can have multiple input or output pads which are
+   hooked up to e.g. HDMI connectors. Even though the subdevice will
+   receive or transmit video from/to only one of those pads, the other pads
+   can still be active when it comes to EDID (Extended Display
+   Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
+   Content Protection System, :ref:`hdcp`) processing, allowing the
+   device to do the fairly slow EDID/HDCP handling in advance. This allows
+   for quick switching between connectors.
+
+These pads appear in several of the controls in this section as
+bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
+1, etc. The maximum value of the control is the set of valid pads.
+
+
+.. _dv-control-id:
+
+Digital Video Control IDs
+=========================
+
+``V4L2_CID_DV_CLASS (class)``
+    The Digital Video class descriptor.
+
+``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
+    Many connectors have a hotplug pin which is high if EDID information
+    is available from the source. This control shows the state of the
+    hotplug pin as seen by the transmitter. Each bit corresponds to an
+    output pad on the transmitter. If an output pad does not have an
+    associated hotplug pin, then the bit for that pad will be 0. This
+    read-only control is applicable to DVI-D, HDMI and DisplayPort
+    connectors.
+
+``V4L2_CID_DV_TX_RXSENSE (bitmask)``
+    Rx Sense is the detection of pull-ups on the TMDS clock lines. This
+    normally means that the sink has left/entered standby (i.e. the
+    transmitter can sense that the receiver is ready to receive video).
+    Each bit corresponds to an output pad on the transmitter. If an
+    output pad does not have an associated Rx Sense, then the bit for
+    that pad will be 0. This read-only control is applicable to DVI-D
+    and HDMI devices.
+
+``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
+    When the transmitter sees the hotplug signal from the receiver it
+    will attempt to read the EDID. If set, then the transmitter has read
+    at least the first block (= 128 bytes). Each bit corresponds to an
+    output pad on the transmitter. If an output pad does not support
+    EDIDs, then the bit for that pad will be 0. This read-only control
+    is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_MODE``
+    (enum)
+
+enum v4l2_dv_tx_mode -
+    HDMI transmitters can transmit in DVI-D mode (just video) or in HDMI
+    mode (video + audio + auxiliary data). This control selects which
+    mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
+    This control is applicable to HDMI connectors.
+
+``V4L2_CID_DV_TX_RGB_RANGE``
+    (enum)
+
+enum v4l2_dv_rgb_range -
+    Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO
+    follows the RGB quantization range specified in the standard for the
+    video interface (ie. :ref:`cea861` for HDMI).
+    V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
+    standard to be compatible with sinks that have not implemented the
+    standard correctly (unfortunately quite common for HDMI and DVI-D).
+    Full range allows all possible values to be used whereas limited
+    range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
+    the number of bits per component. This control is applicable to VGA,
+    DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_IT_CONTENT_TYPE``
+    (enum)
+
+enum v4l2_dv_it_content_type -
+    Configures the IT Content Type of the transmitted video. This
+    information is sent over HDMI and DisplayPort connectors as part of
+    the AVI InfoFrame. The term 'IT Content' is used for content that
+    originates from a computer as opposed to content from a TV broadcast
+    or an analog source. The enum v4l2_dv_it_content_type defines
+    the possible content types:
+
+.. tabularcolumns:: |p{7.3cm}|p{10.4cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_DV_IT_CONTENT_TYPE_GRAPHICS``
+      - Graphics content. Pixel data should be passed unfiltered and
+	without analog reconstruction.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_PHOTO``
+      - Photo content. The content is derived from digital still pictures.
+	The content should be passed through with minimal scaling and
+	picture enhancements.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_CINEMA``
+      - Cinema content.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_GAME``
+      - Game content. Audio and video latency should be minimized.
+    * - ``V4L2_DV_IT_CONTENT_TYPE_NO_ITC``
+      - No IT Content information is available and the ITC bit in the AVI
+	InfoFrame is set to 0.
+
+
+
+``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
+    Detects whether the receiver receives power from the source (e.g.
+    HDMI carries 5V on one of the pins). This is often used to power an
+    eeprom which contains EDID information, such that the source can
+    read the EDID even if the sink is in standby/power off. Each bit
+    corresponds to an input pad on the receiver. If an input pad
+    cannot detect whether power is present, then the bit for that pad
+    will be 0. This read-only control is applicable to DVI-D, HDMI and
+    DisplayPort connectors.
+
+``V4L2_CID_DV_RX_RGB_RANGE``
+    (enum)
+
+enum v4l2_dv_rgb_range -
+    Select the quantization range for RGB input. V4L2_DV_RANGE_AUTO
+    follows the RGB quantization range specified in the standard for the

+***********************
+Flash Control Reference
+***********************
+
+The V4L2 flash controls are intended to provide generic access to flash
+controller devices. Flash controller devices are typically used in
+digital cameras.
+
+The interface can support both LED and xenon flash devices. As of
+writing this, there is no xenon flash driver using this interface.
+
+
+.. _flash-controls-use-cases:
+
+Supported use cases
+===================
+
+
+Unsynchronised LED flash (software strobe)
+------------------------------------------
+
+Unsynchronised LED flash is controlled directly by the host as the
+sensor. The flash must be enabled by the host before the exposure of the
+image starts and disabled once it ends. The host is fully responsible
+for the timing of the flash.
+
+Example of such device: Nokia N900.
+
+
+Synchronised LED flash (hardware strobe)
+----------------------------------------
+
+The synchronised LED flash is pre-programmed by the host (power and
+timeout) but controlled by the sensor through a strobe signal from the
+sensor to the flash.
+
+The sensor controls the flash duration and timing. This information
+typically must be made available to the sensor.
+
+
+LED flash as torch
+------------------
+
+LED flash may be used as torch in conjunction with another use case
+involving camera or individually.
+
+
+.. _flash-control-id:
+

+
+``V4L2_CID_FLASH_CLASS (class)``
+    The FLASH class descriptor.
+
+``V4L2_CID_FLASH_LED_MODE (menu)``
+    Defines the mode of the flash LED, the high-power white LED attached
+    to the flash controller. Setting this control may not be possible in
+    presence of some faults. See V4L2_CID_FLASH_FAULT.

+    * - ``V4L2_FLASH_LED_MODE_TORCH``
+      - Torch mode. See V4L2_CID_FLASH_TORCH_INTENSITY.
+
+
+
+``V4L2_CID_FLASH_STROBE_SOURCE (menu)``
+    Defines the source of the flash LED strobe.
+
+.. tabularcolumns:: |p{7.5cm}|p{10.0cm}|
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_FLASH_STROBE_SOURCE_SOFTWARE``
+      - The flash strobe is triggered by using the
+	V4L2_CID_FLASH_STROBE control.
+    * - ``V4L2_FLASH_STROBE_SOURCE_EXTERNAL``
+      - The flash strobe is triggered by an external source. Typically
+	this is a sensor, which makes it possible to synchronise the
+	flash strobe start to exposure start.
+
+
+
+``V4L2_CID_FLASH_STROBE (button)``
+    Strobe flash. Valid when V4L2_CID_FLASH_LED_MODE is set to
+    V4L2_FLASH_LED_MODE_FLASH and V4L2_CID_FLASH_STROBE_SOURCE
+    is set to V4L2_FLASH_STROBE_SOURCE_SOFTWARE. Setting this
+    control may not be possible in presence of some faults. See
+    V4L2_CID_FLASH_FAULT.
+
+``V4L2_CID_FLASH_STROBE_STOP (button)``
+    Stop flash strobe immediately.
+
+``V4L2_CID_FLASH_STROBE_STATUS (boolean)``
+    Strobe status: whether the flash is strobing at the moment or not.
+    This is a read-only control.
+
+``V4L2_CID_FLASH_TIMEOUT (integer)``
+    Hardware timeout for flash. The flash strobe is stopped after this
+    period of time has passed from the start of the strobe.
+
+``V4L2_CID_FLASH_INTENSITY (integer)``
+    Intensity of the flash strobe when the flash LED is in flash mode
+    (V4L2_FLASH_LED_MODE_FLASH). The unit should be milliamps (mA)
+    if possible.
+
+``V4L2_CID_FLASH_TORCH_INTENSITY (integer)``
+    Intensity of the flash LED in torch mode
+    (V4L2_FLASH_LED_MODE_TORCH). The unit should be milliamps (mA)
+    if possible. Setting this control may not be possible in presence of
+    some faults. See V4L2_CID_FLASH_FAULT.
+
+``V4L2_CID_FLASH_INDICATOR_INTENSITY (integer)``
+    Intensity of the indicator LED. The indicator LED may be fully
+    independent of the flash LED. The unit should be microamps (uA) if
+    possible.
+
+``V4L2_CID_FLASH_FAULT (bitmask)``
+    Faults related to the flash. The faults tell about specific problems
+    in the flash chip itself or the LEDs attached to it. Faults may
+    prevent further use of some of the flash controls. In particular,
+    V4L2_CID_FLASH_LED_MODE is set to V4L2_FLASH_LED_MODE_NONE
+    if the fault affects the flash LED. Exactly which faults have such
+    an effect is chip dependent. Reading the faults resets the control
+    and returns the chip to a usable state if possible.

+      - The flash controller has detected a short or open circuit
+	condition on the indicator LED.
+    * - ``V4L2_FLASH_FAULT_UNDER_VOLTAGE``
+      - Flash controller voltage to the flash LED has been below the
+	minimum limit specific to the flash controller.
+    * - ``V4L2_FLASH_FAULT_INPUT_VOLTAGE``
+      - The input voltage of the flash controller is below the limit under
+	which strobing the flash at full current will not be possible.The
+	condition persists until this flag is no longer set.
+    * - ``V4L2_FLASH_FAULT_LED_OVER_TEMPERATURE``
+      - The temperature of the LED has exceeded its allowed upper limit.
+
+
+
+``V4L2_CID_FLASH_CHARGE (boolean)``
+    Enable or disable charging of the xenon flash capacitor.
+
+``V4L2_CID_FLASH_READY (boolean)``
+    Is the flash ready to strobe? Xenon flashes require their capacitors
+    charged before strobing. LED flashes often require a cooldown period
+    after strobe during which another strobe will not be possible. This
+    is a read-only control.

+FM_RX Control IDs
+=================
+
+``V4L2_CID_FM_RX_CLASS (class)``
+    The FM_RX class descriptor. Calling
+    :ref:`VIDIOC_QUERYCTRL` for this control will
+    return a description of this control class.
+
+``V4L2_CID_RDS_RECEPTION (boolean)``
+    Enables/disables RDS reception by the radio tuner
+
+``V4L2_CID_RDS_RX_PTY (integer)``
+    Gets RDS Programme Type field. This encodes up to 31 pre-defined
+    programme types.
+
+``V4L2_CID_RDS_RX_PS_NAME (string)``
+    Gets the Programme Service name (PS_NAME). It is intended for
+    static display on a receiver. It is the primary aid to listeners in
+    programme service identification and selection. In Annex E of
+    :ref:`iec62106`, the RDS specification, there is a full
+    description of the correct character encoding for Programme Service
+    name strings. Also from RDS specification, PS is usually a single
+    eight character text. However, it is also possible to find receivers
+    which can scroll strings sized as 8 x N characters. So, this control
+    must be configured with steps of 8 characters. The result is it must
+    always contain a string with size multiple of 8.
+
+``V4L2_CID_RDS_RX_RADIO_TEXT (string)``
+    Gets the Radio Text info. It is a textual description of what is
+    being broadcasted. RDS Radio Text can be applied when broadcaster
+    wishes to transmit longer PS names, programme-related information or
+    any other text. In these cases, RadioText can be used in addition to
+    ``V4L2_CID_RDS_RX_PS_NAME``. The encoding for Radio Text strings is
+    also fully described in Annex E of :ref:`iec62106`. The length of
+    Radio Text strings depends on which RDS Block is being used to

+FM Transmitter Control Reference
+********************************
+
+The FM Transmitter (FM_TX) class includes controls for common features
+of FM transmissions capable devices. Currently this class includes
+parameters for audio compression, pilot tone generation, audio deviation
+limiter, RDS transmission and tuning power features.
+
+
+.. _fm-tx-control-id:
+
+FM_TX Control IDs
+=================
+
+``V4L2_CID_FM_TX_CLASS (class)``
+    The FM_TX class descriptor. Calling
+    :ref:`VIDIOC_QUERYCTRL` for this control will
+    return a description of this control class.
+
+``V4L2_CID_RDS_TX_DEVIATION (integer)``
+    Configures RDS signal frequency deviation level in Hz. The range and
+    step are driver-specific.
+
+``V4L2_CID_RDS_TX_PI (integer)``
+    Sets the RDS Programme Identification field for transmission.
+
+``V4L2_CID_RDS_TX_PTY (integer)``
+    Sets the RDS Programme Type field for transmission. This encodes up
+    to 31 pre-defined programme types.
+
+``V4L2_CID_RDS_TX_PS_NAME (string)``
+    Sets the Programme Service name (PS_NAME) for transmission. It is
+    intended for static display on a receiver. It is the primary aid to
+    listeners in programme service identification and selection. In
+    Annex E of :ref:`iec62106`, the RDS specification, there is a full
+    description of the correct character encoding for Programme Service
+    name strings. Also from RDS specification, PS is usually a single
+    eight character text. However, it is also possible to find receivers
+    which can scroll strings sized as 8 x N characters. So, this control
+    must be configured with steps of 8 characters. The result is it must
+    always contain a string with size multiple of 8.
+
+``V4L2_CID_RDS_TX_RADIO_TEXT (string)``
+    Sets the Radio Text info for transmission. It is a textual
+    description of what is being broadcasted. RDS Radio Text can be
+    applied when broadcaster wishes to transmit longer PS names,
+    programme-related information or any other text. In these cases,
+    RadioText should be used in addition to ``V4L2_CID_RDS_TX_PS_NAME``.
+    The encoding for Radio Text strings is also fully described in Annex
+    E of :ref:`iec62106`. The length of Radio Text strings depends on
+    which RDS Block is being used to transmit it, either 32 (2A block)
+    or 64 (2B block). However, it is also possible to find receivers
+    which can scroll strings sized as 32 x N or 64 x N characters. So,
+    this control must be configured with steps of 32 or 64 characters.
+    The result is it must always contain a string with size multiple of
+    32 or 64.
+
+``V4L2_CID_RDS_TX_MONO_STEREO (boolean)``
+    Sets the Mono/Stereo bit of the Decoder Identification code. If set,
+    then the audio was recorded as stereo.
+
+``V4L2_CID_RDS_TX_ARTIFICIAL_HEAD (boolean)``
+    Sets the
+    `Artificial Head <http://en.wikipedia.org/wiki/Artificial_head>`__
+    bit of the Decoder Identification code. If set, then the audio was
+    recorded using an artificial head.
+
+``V4L2_CID_RDS_TX_COMPRESSED (boolean)``
+    Sets the Compressed bit of the Decoder Identification code. If set,
+    then the audio is compressed.
+
+``V4L2_CID_RDS_TX_DYNAMIC_PTY (boolean)``
+    Sets the Dynamic PTY bit of the Decoder Identification code. If set,
+    then the PTY code is dynamically switched.
+
+``V4L2_CID_RDS_TX_TRAFFIC_ANNOUNCEMENT (boolean)``
+    If set, then a traffic announcement is in progress.
+
+``V4L2_CID_RDS_TX_TRAFFIC_PROGRAM (boolean)``
+    If set, then the tuned programme carries traffic announcements.
+
+``V4L2_CID_RDS_TX_MUSIC_SPEECH (boolean)``
+    If set, then this channel broadcasts music. If cleared, then it
+    broadcasts speech. If the transmitter doesn't make this distinction,
+    then it should be set.
+
+``V4L2_CID_RDS_TX_ALT_FREQS_ENABLE (boolean)``
+    If set, then transmit alternate frequencies.
+
+``V4L2_CID_RDS_TX_ALT_FREQS (__u32 array)``
+    The alternate frequencies in kHz units. The RDS standard allows for
+    up to 25 frequencies to be defined. Drivers may support fewer
+    frequencies so check the array size.
+
+``V4L2_CID_AUDIO_LIMITER_ENABLED (boolean)``
+    Enables or disables the audio deviation limiter feature. The limiter
+    is useful when trying to maximize the audio volume, minimize
+    receiver-generated distortion and prevent overmodulation.
+
+``V4L2_CID_AUDIO_LIMITER_RELEASE_TIME (integer)``
+    Sets the audio deviation limiter feature release time. Unit is in
+    useconds. Step and range are driver-specific.
+
+``V4L2_CID_AUDIO_LIMITER_DEVIATION (integer)``
+    Configures audio frequency deviation level in Hz. The range and step
+    are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_ENABLED (boolean)``
+    Enables or disables the audio compression feature. This feature
+    amplifies signals below the threshold by a fixed gain and compresses
+    audio signals above the threshold by the ratio of Threshold/(Gain +
+    Threshold).
+
+``V4L2_CID_AUDIO_COMPRESSION_GAIN (integer)``
+    Sets the gain for audio compression feature. It is a dB value. The
+    range and step are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_THRESHOLD (integer)``
+    Sets the threshold level for audio compression freature. It is a dB
+    value. The range and step are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_ATTACK_TIME (integer)``
+    Sets the attack time for audio compression feature. It is a useconds
+    value. The range and step are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_RELEASE_TIME (integer)``
+    Sets the release time for audio compression feature. It is a
+    useconds value. The range and step are driver-specific.
+
+``V4L2_CID_PILOT_TONE_ENABLED (boolean)``
+    Enables or disables the pilot tone generation feature.
+
+``V4L2_CID_PILOT_TONE_DEVIATION (integer)``
+    Configures pilot tone frequency deviation level. Unit is in Hz. The
+    range and step are driver-specific.
+
+``V4L2_CID_PILOT_TONE_FREQUENCY (integer)``
+    Configures pilot tone frequency value. Unit is in Hz. The range and
+    step are driver-specific.
+
+``V4L2_CID_TUNE_PREEMPHASIS``
+    (enum)
+
+enum v4l2_preemphasis -
+    Configures the pre-emphasis value for broadcasting. A pre-emphasis
+    filter is applied to the broadcast to accentuate the high audio
+    frequencies. Depending on the region, a time constant of either 50
+    or 75 useconds is used. The enum v4l2_preemphasis defines possible
+    values for pre-emphasis. Here they are:
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+    * - ``V4L2_PREEMPHASIS_DISABLED``
+      - No pre-emphasis is applied.
+    * - ``V4L2_PREEMPHASIS_50_uS``
+      - A pre-emphasis of 50 uS is used.
+    * - ``V4L2_PREEMPHASIS_75_uS``
+      - A pre-emphasis of 75 uS is used.
+
+
+
+``V4L2_CID_TUNE_POWER_LEVEL (integer)``
+    Sets the output power level for signal transmission. Unit is in
+    dBuV. Range and step are driver-specific.
+
+``V4L2_CID_TUNE_ANTENNA_CAPACITOR (integer)``
+    This selects the value of antenna tuning capacitor manually or
+    automatically if set to zero. Unit, range and step are
+    driver-specific.

+Image Process Control IDs
+=========================
+
+``V4L2_CID_IMAGE_PROC_CLASS (class)``
+    The IMAGE_PROC class descriptor.
+
+``V4L2_CID_LINK_FREQ (integer menu)``
+    Data bus frequency. Together with the media bus pixel code, bus type
+    (clock cycles per sample), the data bus frequency defines the pixel
+    rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
+    elsewhere, if the device is not an image sensor). The frame rate can
+    be calculated from the pixel clock, image width and height and
+    horizontal and vertical blanking. While the pixel rate control may
+    be defined elsewhere than in the subdev containing the pixel array,
+    the frame rate cannot be obtained from that information. This is
+    because only on the pixel array it can be assumed that the vertical
+    and horizontal blanking information is exact: no other blanking is
+    allowed in the pixel array. The selection of frame rate is performed
+    by selecting the desired horizontal and vertical blanking. The unit
+    of this control is Hz.
+
+``V4L2_CID_PIXEL_RATE (64-bit integer)``
+    Pixel rate in the source pads of the subdev. This control is
+    read-only and its unit is pixels / second.
+
+``V4L2_CID_TEST_PATTERN (menu)``
+    Some capture/display/sensor devices have the capability to generate
+    test pattern images. These hardware specific test patterns can be
+    used to test if a device is working properly.
+
+``V4L2_CID_DEINTERLACING_MODE (menu)``
+    The video deinterlacing mode (such as Bob, Weave, ...). The menu items are
+    driver specific and are documented in :ref:`v4l-drivers`.
+
+``V4L2_CID_DIGITAL_GAIN (integer)``
+    Digital gain is the value by which all colour components
+    are multiplied by. Typically the digital gain applied is the
+    control value divided by e.g. 0x100, meaning that to get no
+    digital gain the control value needs to be 0x100. The no-gain
+    configuration is also typically the default.

+RF Tuner Control Reference
+**************************
+
+The RF Tuner (RF_TUNER) class includes controls for common features of
+devices having RF tuner.
+
+In this context, RF tuner is radio receiver circuit between antenna and
+demodulator. It receives radio frequency (RF) from the antenna and
+converts that received signal to lower intermediate frequency (IF) or
+baseband frequency (BB). Tuners that could do baseband output are often
+called Zero-IF tuners. Older tuners were typically simple PLL tuners
+inside a metal box, while newer ones are highly integrated chips
+without a metal box "silicon tuners". These controls are mostly
+applicable for new feature rich silicon tuners, just because older
+tuners does not have much adjustable features.
+
+For more information about RF tuners see
+`Tuner (radio) <http://en.wikipedia.org/wiki/Tuner_%28radio%29>`__

+Extended Controls API
+*********************
+
+
+Introduction
+============
+
+The control mechanism as originally designed was meant to be used for
+user settings (brightness, saturation, etc). However, it turned out to
+be a very useful model for implementing more complicated driver APIs
+where each driver implements only a subset of a larger API.
+
+The MPEG encoding API was the driving force behind designing and
+implementing this extended control mechanism: the MPEG standard is quite
+large and the currently supported hardware MPEG encoders each only
+implement a subset of this standard. Further more, many parameters
+relating to how the video is encoded into an MPEG stream are specific to
+the MPEG encoding chip since the MPEG standard only defines the format
+of the resulting MPEG stream, not how the video is actually encoded into
+that format.
+
+Unfortunately, the original control API lacked some features needed for
+these new uses and so it was extended into the (not terribly originally
+named) extended control API.
+
+Even though the MPEG encoding API was the first effort to use the
+Extended Control API, nowadays there are also other classes of Extended
+Controls, such as Camera Controls and FM Transmitter Controls. The
+Extended Controls API as well as all Extended Controls classes are
+described in the following text.
+
+
+The Extended Control API
+========================
+
+Three new ioctls are available:
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`. These ioctls act
+on arrays of controls (as opposed to the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls that act on a single
+control). This is needed since it is often required to atomically change
+several controls at once.
+
+Each of the new ioctls expects a pointer to a struct
+:c:type:`v4l2_ext_controls`. This structure
+contains a pointer to the control array, a count of the number of
+controls in that array and a control class. Control classes are used to
+group similar controls into a single class. For example, control class
+``V4L2_CTRL_CLASS_USER`` contains all user controls (i. e. all controls
+that can also be set using the old :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
+ioctl). Control class ``V4L2_CTRL_CLASS_MPEG`` contains all controls
+relating to MPEG encoding, etc.
+
+All controls in the control array must belong to the specified control
+class. An error is returned if this is not the case.
+
+It is also possible to use an empty control array (``count`` == 0) to check
+whether the specified control class is supported.
+
+The control array is a struct
+:c:type:`v4l2_ext_control` array. The
+struct :c:type:`v4l2_ext_control` is very similar to
+struct :c:type:`v4l2_control`, except for the fact that
+it also allows for 64-bit values and pointers to be passed.
+
+Since the struct :c:type:`v4l2_ext_control` supports
+pointers it is now also possible to have controls with compound types
+such as N-dimensional arrays and/or structures. You need to specify the
+``V4L2_CTRL_FLAG_NEXT_COMPOUND`` when enumerating controls to actually
+be able to see such compound controls. In other words, these controls
+with compound types should only be used programmatically.
+
+Since such compound controls need to expose more information about
+themselves than is possible with :ref:`VIDIOC_QUERYCTRL <VIDIOC_QUERYCTRL>`
+the :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>` ioctl was added. In
+particular, this ioctl gives the dimensions of the N-dimensional array if
+this control consists of more than one element.
+
+.. note::
+
+   #. It is important to realize that due to the flexibility of controls it is
+      necessary to check whether the control you want to set actually is
+      supported in the driver and what the valid range of values is. So use
+      :ref:`VIDIOC_QUERYCTRL` to check this.
+
+   #. It is possible that some of the menu indices in a control of
+      type ``V4L2_CTRL_TYPE_MENU`` may not be supported (``VIDIOC_QUERYMENU``
+      will return an error). A good example is the list of supported MPEG
+      audio bitrates. Some drivers only support one or two bitrates, others
+      support a wider range.
+
+All controls use machine endianness.
+
+
+Enumerating Extended Controls
+=============================
+
+The recommended way to enumerate over the extended controls is by using
+:ref:`VIDIOC_QUERYCTRL` in combination with the
+``V4L2_CTRL_FLAG_NEXT_CTRL`` flag:
+
+
+.. code-block:: c
+
+    struct v4l2_queryctrl qctrl;
+
+    qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
+    while (0 == ioctl (fd, VIDIOC_QUERYCTRL, &qctrl)) {
+	/* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+    }
+
+The initial control ID is set to 0 ORed with the
+``V4L2_CTRL_FLAG_NEXT_CTRL`` flag. The ``VIDIOC_QUERYCTRL`` ioctl will
+return the first control with a higher ID than the specified one. When
+no such controls are found an error is returned.
+
+If you want to get all controls within a specific control class, then
+you can set the initial ``qctrl.id`` value to the control class and add
+an extra check to break out of the loop when a control of another
+control class is found:
+
+
+.. code-block:: c
+
+    qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
+    while (0 == ioctl(fd, VIDIOC_QUERYCTRL, &qctrl)) {
+	if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
+	    break;
+	/* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+    }
+
+The 32-bit ``qctrl.id`` value is subdivided into three bit ranges: the
+top 4 bits are reserved for flags (e. g. ``V4L2_CTRL_FLAG_NEXT_CTRL``)
+and are not actually part of the ID. The remaining 28 bits form the
+control ID, of which the most significant 12 bits define the control
+class and the least significant 16 bits identify the control within the
+control class. It is guaranteed that these last 16 bits are always
+non-zero for controls. The range of 0x1000 and up are reserved for
+driver-specific controls. The macro ``V4L2_CTRL_ID2CLASS(id)`` returns
+the control class ID based on a control ID.
+
+If the driver does not support extended controls, then
+``VIDIOC_QUERYCTRL`` will fail when used in combination with
+``V4L2_CTRL_FLAG_NEXT_CTRL``. In that case the old method of enumerating
+control should be used (see :ref:`enum_all_controls`). But if it is
+supported, then it is guaranteed to enumerate over all controls,
+including driver-private controls.
+
+
+Creating Control Panels
+=======================
+
+It is possible to create control panels for a graphical user interface
+where the user can select the various controls. Basically you will have
+to iterate over all controls using the method described above. Each
+control class starts with a control of type
+``V4L2_CTRL_TYPE_CTRL_CLASS``. ``VIDIOC_QUERYCTRL`` will return the name
+of this control class which can be used as the title of a tab page
+within a control panel.
+
+The flags field of struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` also
+contains hints on the behavior of the control. See the
+:ref:`VIDIOC_QUERYCTRL` documentation for more
+details.

+
+***********
+Field Order
+***********
+
+We have to distinguish between progressive and interlaced video.
+Progressive video transmits all lines of a video image sequentially.
+Interlaced video divides an image into two fields, containing only the
+odd and even lines of the image, respectively. Alternating the so called
+odd and even field are transmitted, and due to a small delay between
+fields a cathode ray TV displays the lines interleaved, yielding the
+original frame. This curious technique was invented because at refresh
+rates similar to film the image would fade out too quickly. Transmitting
+fields reduces the flicker without the necessity of doubling the frame
+rate and with it the bandwidth required for each channel.
+
+It is important to understand a video camera does not expose one frame
+at a time, merely transmitting the frames separated into fields. The
+fields are in fact captured at two different instances in time. An
+object on screen may well move between one field and the next. For
+applications analysing motion it is of paramount importance to recognize
+which field of a frame is older, the *temporal order*.
+
+When the driver provides or accepts images field by field rather than
+interleaved, it is also important applications understand how the fields
+combine to frames. We distinguish between top (aka odd) and bottom (aka
+even) fields, the *spatial order*: The first line of the top field is
+the first line of an interlaced frame, the first line of the bottom
+field is the second line of that frame.
+
+However because fields were captured one after the other, arguing
+whether a frame commences with the top or bottom field is pointless. Any
+two successive top and bottom, or bottom and top fields yield a valid
+frame. Only when the source was progressive to begin with, e. g. when
+transferring film to video, two fields may come from the same frame,
+creating a natural order.
+
+Counter to intuition the top field is not necessarily the older field.
+Whether the older field contains the top or bottom lines is a convention
+determined by the video standard. Hence the distinction between temporal
+and spatial order of fields. The diagrams below should make this
+clearer.
+
+In V4L it is assumed that all video cameras transmit fields on the media
+bus in the same order they were captured, so if the top field was
+captured first (is the older field), the top field is also transmitted
+first on the bus.
+
+All video capture and output devices must report the current field
+order. Some drivers may permit the selection of a different order, to
+this end applications initialize the ``field`` field of struct
+:c:type:`v4l2_pix_format` before calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. If this is not desired it
+should have the value ``V4L2_FIELD_ANY`` (0).
+
+
+enum v4l2_field
+===============
+
+.. c:type:: v4l2_field
+
+.. tabularcolumns:: |p{5.8cm}|p{0.6cm}|p{11.1cm}|
+
+.. cssclass:: longtable
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+    :widths:       3 1 4
+
+    * - ``V4L2_FIELD_ANY``
+      - 0
+      - Applications request this field order when any field format
+	is acceptable. Drivers choose depending on hardware capabilities or
+	e.g. the requested image size, and return the actual field order.
+	Drivers must never return ``V4L2_FIELD_ANY``.
+	If multiple field orders are possible the
+	driver must choose one of the possible field orders during
+	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
+	:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`. struct
+	:c:type:`v4l2_buffer` ``field`` can never be
+	``V4L2_FIELD_ANY``.
+    * - ``V4L2_FIELD_NONE``
+      - 1
+      - Images are in progressive (frame-based) format, not interlaced
+        (field-based).
+    * - ``V4L2_FIELD_TOP``
+      - 2
+      - Images consist of the top (aka odd) field only.
+    * - ``V4L2_FIELD_BOTTOM``
+      - 3
+      - Images consist of the bottom (aka even) field only. Applications
+	may wish to prevent a device from capturing interlaced images
+	because they will have "comb" or "feathering" artefacts around
+	moving objects.
+    * - ``V4L2_FIELD_INTERLACED``
+      - 4
+      - Images contain both fields, interleaved line by line. The temporal
+	order of the fields (whether the top or bottom field is older)
+	depends on the current video standard. In M/NTSC the bottom
+	field is the older field. In all other standards the top field
+	is the older field.
+    * - ``V4L2_FIELD_SEQ_TB``
+      - 5
+      - Images contain both fields, the top field lines are stored first
+	in memory, immediately followed by the bottom field lines. Fields
+	are always stored in temporal order, the older one first in
+	memory. Image sizes refer to the frame, not fields.
+    * - ``V4L2_FIELD_SEQ_BT``
+      - 6
+      - Images contain both fields, the bottom field lines are stored
+	first in memory, immediately followed by the top field lines.
+	Fields are always stored in temporal order, the older one first in
+	memory. Image sizes refer to the frame, not fields.
+    * - ``V4L2_FIELD_ALTERNATE``
+      - 7
+      - The two fields of a frame are passed in separate buffers, in
+	temporal order, i. e. the older one first. To indicate the field
+	parity (whether the current field is a top or bottom field) the
+	driver or application, depending on data direction, must set
+	struct :c:type:`v4l2_buffer` ``field`` to
+	``V4L2_FIELD_TOP`` or ``V4L2_FIELD_BOTTOM``. Any two successive
+	fields pair to build a frame. If fields are successive, without
+	any dropped fields between them (fields can drop individually),
+	can be determined from the struct
+	:c:type:`v4l2_buffer` ``sequence`` field. This
+	format cannot be selected when using the read/write I/O method
+	since there is no way to communicate if a field was a top or
+	bottom field.
+    * - ``V4L2_FIELD_INTERLACED_TB``
+      - 8
+      - Images contain both fields, interleaved line by line, top field
+	first. The top field is the older field.
+    * - ``V4L2_FIELD_INTERLACED_BT``
+      - 9
+      - Images contain both fields, interleaved line by line, top field
+	first. The bottom field is the older field.

+Data Formats
+************
+
+
+Data Format Negotiation
+=======================
+
+Different devices exchange different kinds of data with applications,
+for example video images, raw or sliced VBI data, RDS datagrams. Even
+within one kind many different formats are possible, in particular there is an
+abundance of image formats. Although drivers must provide a default and
+the selection persists across closing and reopening a device,
+applications should always negotiate a data format before engaging in
+data exchange. Negotiation means the application asks for a particular
+format and the driver selects and reports the best the hardware can do
+to satisfy the request. Of course applications can also just query the
+current selection.
+
+A single mechanism exists to negotiate all data formats using the
+aggregate struct :c:type:`v4l2_format` and the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls. Additionally the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to examine
+what the hardware *could* do, without actually selecting a new data
+format. The data formats supported by the V4L2 API are covered in the
+respective device section in :ref:`devices`. For a closer look at
+image formats see :ref:`pixfmt`.
+
+The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl is a major turning-point in the
+initialization sequence. Prior to this point multiple panel applications
+can access the same device concurrently to select the current input,
+change controls or modify other properties. The first :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+assigns a logical stream (video data, VBI data etc.) exclusively to one
+file descriptor.
+
+Exclusive means no other application, more precisely no other file
+descriptor, can grab this stream or change device properties
+inconsistent with the negotiated parameters. A video standard change for
+example, when the new standard uses a different number of scan lines,
+can invalidate the selected image format. Therefore only the file
+descriptor owning the stream can make invalidating changes. Accordingly
+multiple file descriptors which grabbed different logical streams
+prevent each other from interfering with their settings. When for
+example video overlay is about to start or already in progress,
+simultaneous video capturing may be restricted to the same cropping and
+image size.
+
+When applications omit the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl its locking side
+effects are implied by the next step, the selection of an I/O method
+with the :ref:`VIDIOC_REQBUFS` ioctl or implicit
+with the first :ref:`read() <func-read>` or
+:ref:`write() <func-write>` call.
+
+Generally only one logical stream can be assigned to a file descriptor,
+the exception being drivers permitting simultaneous video capturing and
+overlay using the same file descriptor for compatibility with V4L and
+earlier versions of V4L2. Switching the logical stream or returning into
+"panel mode" is possible by closing and reopening the device. Drivers
+*may* support a switch using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
+
+All drivers exchanging data with applications must support the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. Implementation of the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is highly recommended but optional.
+
+
+Image Format Enumeration
+========================
+
+Apart of the generic format negotiation functions a special ioctl to
+enumerate all image formats supported by video capture, overlay or
+output devices is available. [#f1]_
+
+The :ref:`VIDIOC_ENUM_FMT` ioctl must be supported
+by all drivers exchanging image data with applications.
+
+.. important::
+
+    Drivers are not supposed to convert image formats in kernel space.
+    They must enumerate only formats directly supported by the hardware.
+    If necessary driver writers should publish an example conversion
+    routine or library for integration into applications.
+
+.. [#f1]
+   Enumerating formats an application has no a-priori knowledge of
+   (otherwise it could explicitly ask for them and need not enumerate)
+   seems useless, but there are applications serving as proxy between
+   drivers and the actual video applications for which this is useful.

+
+Description
+===========
+
+The :ref:`ioctl() <func-ioctl>` function is used to program V4L2 devices. The
+argument ``fd`` must be an open file descriptor. An ioctl ``request``
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes. Macros and
+defines specifying V4L2 ioctl requests are located in the
+``videodev2.h`` header file. Applications should use their own copy, not
+include the version in the kernel sources on the system they compile on.
+All V4L2 ioctl requests, their respective function and parameters are
+specified in :ref:`user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+.. code-block:: c
+
+    #include <unistd.h>
+    #include <sys/mman.h>
+
+
+.. c:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+    :name: v4l2-mmap
+
+Arguments
+=========
+
+``start``
+    Map the buffer to this address in the application's address space.
+    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+    multiple of the pagesize and mmap will fail when the specified
+    address cannot be used. Use of this option is discouraged;
+    applications should just specify a ``NULL`` pointer here.
+
+``length``
+    Length of the memory area to map. This must be the same value as
+    returned by the driver in the struct
+    :c:type:`v4l2_buffer` ``length`` field for the
+    single-planar API, and the same value as returned by the driver in
+    the struct :c:type:`v4l2_plane` ``length`` field for
+    the multi-planar API.
+
+``prot``
+    The ``prot`` argument describes the desired memory protection.
+    Regardless of the device type and the direction of data exchange it
+    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+    and write access to image buffers. Drivers should support at least
+    this combination of flags.
+
+    .. note::
+
+      #. The Linux ``videobuf`` kernel module, which is used by some
+	 drivers supports only ``PROT_READ`` | ``PROT_WRITE``. When the
+	 driver does not support the desired protection, the
+	 :ref:`mmap() <func-mmap>` function fails.
+
+      #. Device memory accesses (e. g. the memory on a graphics card
+	 with video capturing hardware) may incur a performance penalty
+	 compared to main memory accesses, or reads may be significantly
+	 slower than writes or vice versa. Other I/O methods may be more
+	 efficient in such case.
+
+``flags``
+    The ``flags`` parameter specifies the type of the mapped object,
+    mapping options and whether modifications made to the mapped copy of
+    the page are private to the process or are to be shared with other
+    references.
+
+    ``MAP_FIXED`` requests that the driver selects no other address than
+    the one specified. If the specified address cannot be used,
+    :ref:`mmap() <func-mmap>` will fail. If ``MAP_FIXED`` is specified,
+    ``start`` must be a multiple of the pagesize. Use of this option is
+    discouraged.
+
+    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+    ``MAP_SHARED`` allows applications to share the mapped memory with
+    other (e. g. child-) processes.
+
+    .. note::
+
+       The Linux ``videobuf`` module  which is used by some
+       drivers supports only ``MAP_SHARED``. ``MAP_PRIVATE`` requests
+       copy-on-write semantics. V4L2 applications should not set the
+       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+       flags.
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``offset``
+    Offset of the buffer in device memory. This must be the same value
+    as returned by the driver in the struct
+    :c:type:`v4l2_buffer` ``m`` union ``offset`` field for
+    the single-planar API, and the same value as returned by the driver
+    in the struct :c:type:`v4l2_plane` ``m`` union
+    ``mem_offset`` field for the multi-planar API.
+
+
+Description
+===========
+
+The :ref:`mmap() <func-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`VIDIOC_QUERYBUF` ioctl. Buffers must be
+allocated with the :ref:`VIDIOC_REQBUFS` ioctl
+before they can be queried.
+
+To unmap buffers the :ref:`munmap() <func-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <func-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+    ``fd`` is not a valid file descriptor.
+
+EACCES
+    ``fd`` is not open for reading and writing.
+
+EINVAL
+    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
+    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
+
+    The ``flags`` or ``prot`` value is not supported.
+
+    No buffers have been allocated with the
+    :ref:`VIDIOC_REQBUFS` ioctl.
+
+ENOMEM
+    Not enough physical or virtual memory was available to complete the
+    request.

+    technicality, input devices still support only reading and output
+    devices only writing.
+
+    When the ``O_NONBLOCK`` flag is given, the :ref:`read() <func-read>`
+    function and the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will
+    return the ``EAGAIN`` error code when no data is available or no
+    buffer is in the driver outgoing queue, otherwise these functions
+    block until data becomes available. All V4L2 drivers exchanging data
+    with applications must support the ``O_NONBLOCK`` flag.
+
+    Other flags have no effect.
+
+
+Description
+===========
+
+To open a V4L2 device applications call :ref:`open() <func-open>` with the
+desired device name. This function has no side effects; all data format
+parameters, current input or output, control values or other properties
+remain unchanged. At the first :ref:`open() <func-open>` call after loading the
+driver they will be reset to default values, drivers are never in an
+undefined state.
+
+
+Return Value
+============
+
+On success :ref:`open() <func-open>` returns the new file descriptor. On error
+-1 is returned, and the ``errno`` variable is set appropriately.
+Possible error codes are:
+
+EACCES
+    The caller has no permission to access the device.
+
+EBUSY
+    The driver does not support multiple opens and the device is already
+    in use.
+
+ENXIO
+    No device corresponding to this device special file exists.
+
+ENOMEM
+    Not enough kernel memory was available to complete the request.
+
+EMFILE
+    The process already has the maximum number of files open.
+
+ENFILE
+    The limit on the total number of files open on the system has been
+    reached.

+
+v4l2-poll - Wait for some event on a file descriptor
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <sys/poll.h>
+
+
+.. c:function:: int poll( struct pollfd *ufds, unsigned int nfds, int timeout )
+    :name: v4l2-poll
+
+Arguments
+=========
+
+
+
+Description
+===========
+
+With the :ref:`poll() <func-poll>` function applications can suspend execution
+until the driver has captured data or is ready to accept data for
+output.
+
+When streaming I/O has been negotiated this function waits until a
+buffer has been filled by the capture device and can be dequeued with
+the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. For output devices this
+function waits until the device is ready to accept a new buffer to be
+queued up with the :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl for
+display. When buffers are already in the outgoing queue of the driver
+(capture) or the incoming queue isn't full (display) the function
+returns immediately.
+
+On success :ref:`poll() <func-poll>` returns the number of file descriptors
+that have been selected (that is, file descriptors for which the
+``revents`` field of the respective :c:func:`struct pollfd` structure
+is non-zero). Capture devices set the ``POLLIN`` and ``POLLRDNORM``
+flags in the ``revents`` field, output devices the ``POLLOUT`` and
+``POLLWRNORM`` flags. When the function timed out it returns a value of
+zero, on failure it returns -1 and the ``errno`` variable is set
+appropriately. When the application did not call
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` the :ref:`poll() <func-poll>`
+function succeeds, but sets the ``POLLERR`` flag in the ``revents``
+field. When the application has called
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` for a capture device but
+hasn't yet called :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, the
+:ref:`poll() <func-poll>` function succeeds and sets the ``POLLERR`` flag in
+the ``revents`` field. For output devices this same situation will cause
+:ref:`poll() <func-poll>` to succeed as well, but it sets the ``POLLOUT`` and
+``POLLWRNORM`` flags in the ``revents`` field.
+
+If an event occurred (see :ref:`VIDIOC_DQEVENT`)
+then ``POLLPRI`` will be set in the ``revents`` field and
+:ref:`poll() <func-poll>` will return.
+
+When use of the :ref:`read() <func-read>` function has been negotiated and the
+driver does not capture yet, the :ref:`poll() <func-poll>` function starts
+capturing. When that fails it returns a ``POLLERR`` as above. Otherwise
+it waits until data has been captured and can be read. When the driver
+captures continuously (as opposed to, for example, still images) the
+function may return immediately.
+
+When use of the :ref:`write() <func-write>` function has been negotiated and the
+driver does not stream yet, the :ref:`poll() <func-poll>` function starts
+streaming. When that fails it returns a ``POLLERR`` as above. Otherwise
+it waits until the driver is ready for a non-blocking
+:ref:`write() <func-write>` call.
+
+If the caller is only interested in events (just ``POLLPRI`` is set in
+the ``events`` field), then :ref:`poll() <func-poll>` will *not* start
+streaming if the driver does not stream yet. This makes it possible to
+just poll for events and not for buffers.
+
+All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
+function or streaming I/O must also support the :ref:`poll() <func-poll>`
+function.
+
+For more details see the :ref:`poll() <func-poll>` manual page.
+
+
+Return Value
+============
+
+On success, :ref:`poll() <func-poll>` returns the number structures which have
+non-zero ``revents`` fields, or zero if the call timed out. On error -1
+is returned, and the ``errno`` variable is set appropriately:
+
+EBADF
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+EBUSY
+    The driver does not support multiple read or write streams and the
+    device is already in use.
+
+EFAULT
+    ``ufds`` references an inaccessible memory area.
+
+EINTR
+    The call was interrupted by a signal.
+
+EINVAL
+    The ``nfds`` value exceeds the ``RLIMIT_NOFILE`` value. Use
+    ``getrlimit()`` to obtain this value.

+
+v4l2-read - Read from a V4L2 device
+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+
+
+.. c:function:: ssize_t read( int fd, void *buf, size_t count )
+    :name: v4l2-read
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``buf``
+   Buffer to be filled
+
+``count``
+  Max number of bytes to read
+
+Description
+===========
+
+:ref:`read() <func-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``. The layout of the
+data in the buffer is discussed in the respective device interface
+section, see ##. If ``count`` is zero, :ref:`read() <func-read>` returns zero
+and has no other results. If ``count`` is greater than ``SSIZE_MAX``,
+the result is unspecified. Regardless of the ``count`` value each
+:ref:`read() <func-read>` call will provide at most one frame (two fields)
+worth of data.
+
+By default :ref:`read() <func-read>` blocks until data becomes available. When
+the ``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>`
+function it returns immediately with an ``EAGAIN`` error code when no data
+is available. The :ref:`select() <func-select>` or
+:ref:`poll() <func-poll>` functions can always be used to suspend
+execution until data becomes available. All drivers supporting the
+:ref:`read() <func-read>` function must also support :ref:`select() <func-select>` and
+:ref:`poll() <func-poll>`.
+
+Drivers can implement read functionality in different ways, using a
+single or multiple buffers and discarding the oldest or newest frames
+once the internal buffers are filled.
+
+:ref:`read() <func-read>` never returns a "snapshot" of a buffer being filled.
+Using a single buffer the driver will stop capturing when the
+application starts reading the buffer until the read is finished. Thus
+only the period of the vertical blanking interval is available for
+reading, or the capture rate must fall below the nominal frame rate of
+the video standard.
+
+The behavior of :ref:`read() <func-read>` when called during the active picture
+period or the vertical blanking separating the top and bottom field
+depends on the discarding policy. A driver discarding the oldest frames
+keeps capturing into an internal buffer, continuously overwriting the
+previously, not read frame, and returns the frame being received at the
+time of the :ref:`read() <func-read>` call as soon as it is complete.
+
+A driver discarding the newest frames stops capturing until the next
+:ref:`read() <func-read>` call. The frame being received at :ref:`read() <func-read>`
+time is discarded, returning the following frame instead. Again this
+implies a reduction of the capture rate to one half or less of the
+nominal frame rate. An example of this model is the video read mode of
+the bttv driver, initiating a DMA to user memory when :ref:`read() <func-read>`
+is called and returning when the DMA finished.
+
+In the multiple buffer model drivers maintain a ring of internal
+buffers, automatically advancing to the next free buffer. This allows
+continuous capturing when the application can empty the buffers fast
+enough. Again, the behavior when the driver runs out of free buffers
+depends on the discarding policy.
+
+Applications can get and set the number of buffers used internally by
+the driver with the :ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
+:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctls. They are optional,
+however. The discarding policy is not reported and cannot be changed.
+For minimum requirements see :ref:`devices`.
+
+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame. This may happen for example because
+:ref:`read() <func-read>` was interrupted by a signal. On error, -1 is
+returned, and the ``errno`` variable is set appropriately. In this case
+the next read will start at the beginning of a new frame. Possible error
+codes are:
+
+EAGAIN
+    Non-blocking I/O has been selected using O_NONBLOCK and no data was
+    immediately available for reading.
+
+EBADF
+    ``fd`` is not a valid file descriptor or is not open for reading, or
+    the process already has the maximum number of files open.
+
+EBUSY
+    The driver does not support multiple read streams and the device is
+    already in use.
+
+EFAULT
+    ``buf`` references an inaccessible memory area.
+
+EINTR
+    The call was interrupted by a signal before any data was read.
+
+EIO
+    I/O error. This indicates some hardware problem or a failure to
+    communicate with a remote device (USB camera etc.).
+
+EINVAL
+    The :ref:`read() <func-read>` function is not supported by this driver, not
+    on this device, or generally not on this type of device.

+
+
+Description
+===========
+
+With the :ref:`select() <func-select>` function applications can suspend
+execution until the driver has captured data or is ready to accept data
+for output.
+
+When streaming I/O has been negotiated this function waits until a
+buffer has been filled or displayed and can be dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. When buffers are already in
+the outgoing queue of the driver the function returns immediately.
+
+On success :ref:`select() <func-select>` returns the total number of bits set in
+:c:func:`struct fd_set`. When the function timed out it returns
+a value of zero. On failure it returns -1 and the ``errno`` variable is
+set appropriately. When the application did not call
+:ref:`VIDIOC_QBUF` or
+:ref:`VIDIOC_STREAMON` yet the :ref:`select() <func-select>`
+function succeeds, setting the bit of the file descriptor in ``readfds``
+or ``writefds``, but subsequent :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+calls will fail. [#f1]_
+
+When use of the :ref:`read() <func-read>` function has been negotiated and the
+driver does not capture yet, the :ref:`select() <func-select>` function starts
+capturing. When that fails, :ref:`select() <func-select>` returns successful and
+a subsequent :ref:`read() <func-read>` call, which also attempts to start
+capturing, will return an appropriate error code. When the driver
+captures continuously (as opposed to, for example, still images) and
+data is already available the :ref:`select() <func-select>` function returns
+immediately.
+
+When use of the :ref:`write() <func-write>` function has been negotiated the
+:ref:`select() <func-select>` function just waits until the driver is ready for a
+non-blocking :ref:`write() <func-write>` call.
+
+All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
+function or streaming I/O must also support the :ref:`select() <func-select>`
+function.
+
+For more details see the :ref:`select() <func-select>` manual page.
+
+
+Return Value
+============
+
+On success, :ref:`select() <func-select>` returns the number of descriptors
+contained in the three returned descriptor sets, which will be zero if
+the timeout expired. On error -1 is returned, and the ``errno`` variable
+is set appropriately; the sets and ``timeout`` are undefined. Possible
+error codes are:
+
+EBADF
+    One or more of the file descriptor sets specified a file descriptor

+***********************
+Changes of the V4L2 API
+***********************
+
+Soon after the V4L API was added to the kernel it was criticised as too
+inflexible. In August 1998 Bill Dirks proposed a number of improvements
+and began to work on documentation, example drivers and applications.
+With the help of other volunteers this eventually became the V4L2 API,
+not just an extension but a replacement for the V4L API. However it took
+another four years and two stable kernel releases until the new API was
+finally accepted for inclusion into the kernel in its present form.
+
+
+Early Versions
+==============
+
+1998-08-20: First version.
+
+1998-08-27: The :ref:`select() <func-select>` function was introduced.
+
+1998-09-10: New video standard interface.
+
+1998-09-18: The ``VIDIOC_NONCAP`` ioctl was replaced by the otherwise
+meaningless ``O_TRUNC`` :ref:`open() <func-open>` flag, and the
+aliases ``O_NONCAP`` and ``O_NOIO`` were defined. Applications can set
+this flag if they intend to access controls only, as opposed to capture
+applications which need exclusive access. The ``VIDEO_STD_XXX``
+identifiers are now ordinals instead of flags, and the
+``video_std_construct()`` helper function takes id and
+transmission arguments.
+
+1998-09-28: Revamped video standard. Made video controls individually
+enumerable.
+
+1998-10-02: The ``id`` field was removed from struct
+struct ``video_standard`` and the color subcarrier fields were
+renamed. The :ref:`VIDIOC_QUERYSTD` ioctl was
+renamed to :ref:`VIDIOC_ENUMSTD`,
+:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` to
+:ref:`VIDIOC_ENUMINPUT`. A first draft of the
+Codec API was released.
+
+1998-11-08: Many minor changes. Most symbols have been renamed. Some
+material changes to struct :c:type:`v4l2_capability`.
+
+1998-11-12: The read/write directon of some ioctls was misdefined.
+
+1998-11-14: ``V4L2_PIX_FMT_RGB24`` changed to ``V4L2_PIX_FMT_BGR24``,
+and ``V4L2_PIX_FMT_RGB32`` changed to ``V4L2_PIX_FMT_BGR32``. Audio
+controls are now accessible with the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls under names starting
+with ``V4L2_CID_AUDIO``. The ``V4L2_MAJOR`` define was removed from
+``videodev.h`` since it was only used once in the ``videodev`` kernel
+module. The ``YUV422`` and ``YUV411`` planar image formats were added.
+
+1998-11-28: A few ioctl symbols changed. Interfaces for codecs and video
+output devices were added.
+
+1999-01-14: A raw VBI capture interface was added.
+
+1999-01-19: The ``VIDIOC_NEXTBUF`` ioctl was removed.
+
+
+V4L2 Version 0.16 1999-01-31
+============================
+
+1999-01-27: There is now one QBUF ioctl, VIDIOC_QWBUF and VIDIOC_QRBUF
+are gone. VIDIOC_QBUF takes a v4l2_buffer as a parameter. Added
+digital zoom (cropping) controls.
+
+
+V4L2 Version 0.18 1999-03-16
+============================
+
+Added a v4l to V4L2 ioctl compatibility layer to videodev.c. Driver
+writers, this changes how you implement your ioctl handler. See the
+Driver Writer's Guide. Added some more control id codes.
+
+
+V4L2 Version 0.19 1999-06-05
+============================
+
+1999-03-18: Fill in the category and catname fields of v4l2_queryctrl
+objects before passing them to the driver. Required a minor change to
+the VIDIOC_QUERYCTRL handlers in the sample drivers.
+
+1999-03-31: Better compatibility for v4l memory capture ioctls. Requires
+changes to drivers to fully support new compatibility features, see
+Driver Writer's Guide and v4l2cap.c. Added new control IDs:
+V4L2_CID_HFLIP, _VFLIP. Changed V4L2_PIX_FMT_YUV422P to _YUV422P,
+and _YUV411P to _YUV411P.
+
+1999-04-04: Added a few more control IDs.
+
+1999-04-07: Added the button control type.
+
+1999-05-02: Fixed a typo in videodev.h, and added the
+V4L2_CTRL_FLAG_GRAYED (later V4L2_CTRL_FLAG_GRABBED) flag.
+
+1999-05-20: Definition of VIDIOC_G_CTRL was wrong causing a
+malfunction of this ioctl.
+
+1999-06-05: Changed the value of V4L2_CID_WHITENESS.
+
+
+V4L2 Version 0.20 (1999-09-10)
+==============================
+
+Version 0.20 introduced a number of changes which were *not backward
+compatible* with 0.19 and earlier versions. Purpose of these changes was
+to simplify the API, while making it more extensible and following
+common Linux driver API conventions.
+
+1. Some typos in ``V4L2_FMT_FLAG`` symbols were fixed. struct
+   :c:type:`v4l2_clip` was changed for compatibility with
+   v4l. (1999-08-30)
+
+2. ``V4L2_TUNER_SUB_LANG1`` was added. (1999-09-05)
+
+3. All ioctl() commands that used an integer argument now take a pointer
+   to an integer. Where it makes sense, ioctls will return the actual
+   new value in the integer pointed to by the argument, a common
+   convention in the V4L2 API. The affected ioctls are: VIDIOC_PREVIEW,
+   VIDIOC_STREAMON, VIDIOC_STREAMOFF, VIDIOC_S_FREQ,
+   VIDIOC_S_INPUT, VIDIOC_S_OUTPUT, VIDIOC_S_EFFECT. For example
+
+
+   .. code-block:: c
+
+       err = ioctl (fd, VIDIOC_XXX, V4L2_XXX);
+
+   becomes
+
+
+   .. code-block:: c
+
+       int a = V4L2_XXX; err = ioctl(fd, VIDIOC_XXX, &a);
+
+4. All the different get- and set-format commands were swept into one
+   :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+   :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl taking a union and a
+   type field selecting the union member as parameter. Purpose is to
+   simplify the API by eliminating several ioctls and to allow new and
+   driver private data streams without adding new ioctls.
+
+   This change obsoletes the following ioctls: ``VIDIOC_S_INFMT``,
+   ``VIDIOC_G_INFMT``, ``VIDIOC_S_OUTFMT``, ``VIDIOC_G_OUTFMT``,
+   ``VIDIOC_S_VBIFMT`` and ``VIDIOC_G_VBIFMT``. The image format
+   structure struct :c:type:`v4l2_format` was renamed to struct
+   :c:type:`v4l2_pix_format`, while struct
+   :c:type:`v4l2_format` is now the envelopping structure
+   for all format negotiations.
+
+5. Similar to the changes above, the ``VIDIOC_G_PARM`` and
+   ``VIDIOC_S_PARM`` ioctls were merged with ``VIDIOC_G_OUTPARM`` and
+   ``VIDIOC_S_OUTPARM``. A ``type`` field in the new struct
+   :c:type:`v4l2_streamparm` selects the respective
+   union member.
+
+   This change obsoletes the ``VIDIOC_G_OUTPARM`` and
+   ``VIDIOC_S_OUTPARM`` ioctls.
+
+6. Control enumeration was simplified, and two new control flags were
+   introduced and one dropped. The ``catname`` field was replaced by a
+   ``group`` field.
+
+   Drivers can now flag unsupported and temporarily unavailable controls
+   with ``V4L2_CTRL_FLAG_DISABLED`` and ``V4L2_CTRL_FLAG_GRABBED``
+   respectively. The ``group`` name indicates a possibly narrower
+   classification than the ``category``. In other words, there may be
+   multiple groups within a category. Controls within a group would
+   typically be drawn within a group box. Controls in different
+   categories might have a greater separation, or may even appear in
+   separate windows.
+
+7. The struct :c:type:`v4l2_buffer` ``timestamp`` was
+   changed to a 64 bit integer, containing the sampling or output time
+   of the frame in nanoseconds. Additionally timestamps will be in
+   absolute system time, not starting from zero at the beginning of a
+   stream. The data type name for timestamps is stamp_t, defined as a
+   signed 64-bit integer. Output devices should not send a buffer out
+   until the time in the timestamp field has arrived. I would like to
+   follow SGI's lead, and adopt a multimedia timestamping system like
+   their UST (Unadjusted System Time). See
+   http://web.archive.org/web/\*/http://reality.sgi.com
+   /cpirazzi_engr/lg/time/intro.html. UST uses timestamps that are
+   64-bit signed integers (not struct timeval's) and given in nanosecond
+   units. The UST clock starts at zero when the system is booted and
+   runs continuously and uniformly. It takes a little over 292 years for
+   UST to overflow. There is no way to set the UST clock. The regular
+   Linux time-of-day clock can be changed periodically, which would
+   cause errors if it were being used for timestamping a multimedia
+   stream. A real UST style clock will require some support in the
+   kernel that is not there yet. But in anticipation, I will change the
+   timestamp field to a 64-bit integer, and I will change the
+   v4l2_masterclock_gettime() function (used only by drivers) to
+   return a 64-bit integer.
+
+8. A ``sequence`` field was added to struct
+   :c:type:`v4l2_buffer`. The ``sequence`` field counts
+   captured frames, it is ignored by output devices. When a capture
+   driver drops a frame, the sequence number of that frame is skipped.
+
+
+V4L2 Version 0.20 incremental changes
+=====================================
+
+1999-12-23: In struct :c:type:`v4l2_vbi_format` the
+``reserved1`` field became ``offset``. Previously drivers were required
+to clear the ``reserved1`` field.
+
+2000-01-13: The ``V4L2_FMT_FLAG_NOT_INTERLACED`` flag was added.
+
+2000-07-31: The ``linux/poll.h`` header is now included by
+``videodev.h`` for compatibility with the original ``videodev.h`` file.
+
+2000-11-20: ``V4L2_TYPE_VBI_OUTPUT`` and ``V4L2_PIX_FMT_Y41P`` were
+added.
+
+2000-11-25: ``V4L2_TYPE_VBI_INPUT`` was added.
+
+2000-12-04: A couple typos in symbol names were fixed.
+
+2001-01-18: To avoid namespace conflicts the ``fourcc`` macro defined in
+the ``videodev.h`` header file was renamed to ``v4l2_fourcc``.
+
+2001-01-25: A possible driver-level compatibility problem between the
+``videodev.h`` file in Linux 2.4.0 and the ``videodev.h`` file included
+in the ``videodevX`` patch was fixed. Users of an earlier version of
+``videodevX`` on Linux 2.4.0 should recompile their V4L and V4L2
+drivers.
+
+2001-01-26: A possible kernel-level incompatibility between the
+``videodev.h`` file in the ``videodevX`` patch and the ``videodev.h``
+file in Linux 2.2.x with devfs patches applied was fixed.
+
+2001-03-02: Certain V4L ioctls which pass data in both direction
+although they are defined with read-only parameter, did not work
+correctly through the backward compatibility layer. [Solution?]
+
+2001-04-13: Big endian 16-bit RGB formats were added.
+
+2001-09-17: New YUV formats and the
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctls were added.
+(The old ``VIDIOC_G_FREQ`` and ``VIDIOC_S_FREQ`` ioctls did not take
+multiple tuners into account.)
+
+2000-09-18: ``V4L2_BUF_TYPE_VBI`` was added. This may *break
+compatibility* as the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls may fail now if the struct
+struct ``v4l2_fmt`` ``type`` field does not contain
+``V4L2_BUF_TYPE_VBI``. In the documentation of the struct
+:c:type:`v4l2_vbi_format` ``offset`` field the
+ambiguous phrase "rising edge" was changed to "leading edge".
+
+
+V4L2 Version 0.20 2000-11-23
+============================
+
+A number of changes were made to the raw VBI interface.
+
+1. Figures clarifying the line numbering scheme were added to the V4L2
+   API specification. The ``start``\ [0] and ``start``\ [1] fields no
+   longer count line numbers beginning at zero. Rationale: a) The
+   previous definition was unclear. b) The ``start``\ [] values are
+   ordinal numbers. c) There is no point in inventing a new line
+   numbering scheme. We now use line number as defined by ITU-R, period.
+   Compatibility: Add one to the start values. Applications depending on
+   the previous semantics may not function correctly.
+
+2. The restriction "count[0] > 0 and count[1] > 0" has been relaxed to
+   "(count[0] + count[1]) > 0". Rationale: Drivers may allocate
+   resources at scan line granularity and some data services are
+   transmitted only on the first field. The comment that both ``count``
+   values will usually be equal is misleading and pointless and has been
+   removed. This change *breaks compatibility* with earlier versions:
+   Drivers may return ``EINVAL``, applications may not function correctly.
+
+3. Drivers are again permitted to return negative (unknown) start values
+   as proposed earlier. Why this feature was dropped is unclear. This
+   change may *break compatibility* with applications depending on the
+   start values being positive. The use of ``EBUSY`` and ``EINVAL``
+   error codes with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl was
+   clarified. The ``EBUSY`` error code was finally documented, and the
+   ``reserved2`` field which was previously mentioned only in the
+   ``videodev.h`` header file.
+
+4. New buffer types ``V4L2_TYPE_VBI_INPUT`` and ``V4L2_TYPE_VBI_OUTPUT``
+   were added. The former is an alias for the old ``V4L2_TYPE_VBI``, the
+   latter was missing in the ``videodev.h`` file.
+
+
+V4L2 Version 0.20 2002-07-25
+============================
+
+Added sliced VBI interface proposal.
+
+
+V4L2 in Linux 2.5.46, 2002-10
+=============================
+
+Around October-November 2002, prior to an announced feature freeze of
+Linux 2.5, the API was revised, drawing from experience with V4L2 0.20.
+This unnamed version was finally merged into Linux 2.5.46.
+
+1.  As specified in :ref:`related`, drivers must make related device
+    functions available under all minor device numbers.
+
+2.  The :ref:`open() <func-open>` function requires access mode
+    ``O_RDWR`` regardless of the device type. All V4L2 drivers
+    exchanging data with applications must support the ``O_NONBLOCK``
+    flag. The ``O_NOIO`` flag, a V4L2 symbol which aliased the
+    meaningless ``O_TRUNC`` to indicate accesses without data exchange
+    (panel applications) was dropped. Drivers must stay in "panel mode"
+    until the application attempts to initiate a data exchange, see
+    :ref:`open`.
+
+3.  The struct :c:type:`v4l2_capability` changed
+    dramatically. Note that also the size of the structure changed,
+    which is encoded in the ioctl request code, thus older V4L2 devices
+    will respond with an ``EINVAL`` error code to the new
+    :ref:`VIDIOC_QUERYCAP` ioctl.
+
+    There are new fields to identify the driver, a new RDS device
+    function ``V4L2_CAP_RDS_CAPTURE``, the ``V4L2_CAP_AUDIO`` flag
+    indicates if the device has any audio connectors, another I/O
+    capability ``V4L2_CAP_ASYNCIO`` can be flagged. In response to these
+    changes the ``type`` field became a bit set and was merged into the
+    ``flags`` field. ``V4L2_FLAG_TUNER`` was renamed to
+    ``V4L2_CAP_TUNER``, ``V4L2_CAP_VIDEO_OVERLAY`` replaced
+    ``V4L2_FLAG_PREVIEW`` and ``V4L2_CAP_VBI_CAPTURE`` and
+    ``V4L2_CAP_VBI_OUTPUT`` replaced ``V4L2_FLAG_DATA_SERVICE``.
+    ``V4L2_FLAG_READ`` and ``V4L2_FLAG_WRITE`` were merged into
+    ``V4L2_CAP_READWRITE``.
+
+    The redundant fields ``inputs``, ``outputs`` and ``audios`` were
+    removed. These properties can be determined as described in
+    :ref:`video` and :ref:`audio`.
+
+    The somewhat volatile and therefore barely useful fields
+    ``maxwidth``, ``maxheight``, ``minwidth``, ``minheight``,
+    ``maxframerate`` were removed. This information is available as
+    described in :ref:`format` and :ref:`standard`.
+
+    ``V4L2_FLAG_SELECT`` was removed. We believe the select() function
+    is important enough to require support of it in all V4L2 drivers
+    exchanging data with applications. The redundant
+    ``V4L2_FLAG_MONOCHROME`` flag was removed, this information is
+    available as described in :ref:`format`.
+
+4.  In struct :c:type:`v4l2_input` the ``assoc_audio``
+    field and the ``capability`` field and its only flag
+    ``V4L2_INPUT_CAP_AUDIO`` was replaced by the new ``audioset`` field.
+    Instead of linking one video input to one audio input this field
+    reports all audio inputs this video input combines with.
+
+    New fields are ``tuner`` (reversing the former link from tuners to
+    video inputs), ``std`` and ``status``.
+
+    Accordingly struct :c:type:`v4l2_output` lost its
+    ``capability`` and ``assoc_audio`` fields. ``audioset``,
+    ``modulator`` and ``std`` where added instead.
+
+5.  The struct :c:type:`v4l2_audio` field ``audio`` was
+    renamed to ``index``, for consistency with other structures. A new
+    capability flag ``V4L2_AUDCAP_STEREO`` was added to indicated if the
+    audio input in question supports stereo sound.
+    ``V4L2_AUDCAP_EFFECTS`` and the corresponding ``V4L2_AUDMODE`` flags
+    where removed. This can be easily implemented using controls.
+    (However the same applies to AVL which is still there.)
+
+    Again for consistency the struct
+    :c:type:`v4l2_audioout` field ``audio`` was renamed
+    to ``index``.
+
+6.  The struct :c:type:`v4l2_tuner` ``input`` field was
+    replaced by an ``index`` field, permitting devices with multiple
+    tuners. The link between video inputs and tuners is now reversed,
+    inputs point to their tuner. The ``std`` substructure became a
+    simple set (more about this below) and moved into struct
+    :c:type:`v4l2_input`. A ``type`` field was added.
+
+    Accordingly in struct :c:type:`v4l2_modulator` the
+    ``output`` was replaced by an ``index`` field.
+
+    In struct :c:type:`v4l2_frequency` the ``port``
+    field was replaced by a ``tuner`` field containing the respective
+    tuner or modulator index number. A tuner ``type`` field was added
+    and the ``reserved`` field became larger for future extensions
+    (satellite tuners in particular).
+
+7.  The idea of completely transparent video standards was dropped.
+    Experience showed that applications must be able to work with video
+    standards beyond presenting the user a menu. Instead of enumerating
+    supported standards with an ioctl applications can now refer to
+    standards by :ref:`v4l2_std_id <v4l2-std-id>` and symbols
+    defined in the ``videodev2.h`` header file. For details see
+    :ref:`standard`. The :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
+    :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` now take a pointer to this
+    type as argument. :ref:`VIDIOC_QUERYSTD` was
+    added to autodetect the received standard, if the hardware has this
+    capability. In struct :c:type:`v4l2_standard` an
+    ``index`` field was added for
+    :ref:`VIDIOC_ENUMSTD`. A
+    :ref:`v4l2_std_id <v4l2-std-id>` field named ``id`` was added as
+    machine readable identifier, also replacing the ``transmission``
+    field. The misleading ``framerate`` field was renamed to
+    ``frameperiod``. The now obsolete ``colorstandard`` information,
+    originally needed to distguish between variations of standards, were
+    removed.
+
+    Struct ``v4l2_enumstd`` ceased to be.
+    :ref:`VIDIOC_ENUMSTD` now takes a pointer to a
+    struct :c:type:`v4l2_standard` directly. The
+    information which standards are supported by a particular video
+    input or output moved into struct :c:type:`v4l2_input`
+    and struct :c:type:`v4l2_output` fields named ``std``,
+    respectively.
+
+8.  The struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` fields
+    ``category`` and ``group`` did not catch on and/or were not
+    implemented as expected and therefore removed.
+
+9.  The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl was added to
+    negotiate data formats as with
+    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, but without the overhead of
+    programming the hardware and regardless of I/O in progress.
+
+    In struct :c:type:`v4l2_format` the ``fmt`` union was
+    extended to contain struct :c:type:`v4l2_window`. All
+    image format negotiations are now possible with ``VIDIOC_G_FMT``,
+    ``VIDIOC_S_FMT`` and ``VIDIOC_TRY_FMT``; ioctl. The ``VIDIOC_G_WIN``
+    and ``VIDIOC_S_WIN`` ioctls to prepare for a video overlay were
+    removed. The ``type`` field changed to type enum
+    :c:type:`v4l2_buf_type` and the buffer type names
+    changed as follows.
+
+
+
+    .. flat-table::
+	:header-rows:  1
+	:stub-columns: 0
+
+	* - Old defines
+	  - enum :c:type:`v4l2_buf_type`
+	* - ``V4L2_BUF_TYPE_CAPTURE``
+	  - ``V4L2_BUF_TYPE_VIDEO_CAPTURE``
+	* - ``V4L2_BUF_TYPE_CODECIN``
+	  - Omitted for now
+	* - ``V4L2_BUF_TYPE_CODECOUT``
+	  - Omitted for now
+	* - ``V4L2_BUF_TYPE_EFFECTSIN``
+	  - Omitted for now
+	* - ``V4L2_BUF_TYPE_EFFECTSIN2``
+	  - Omitted for now
+	* - ``V4L2_BUF_TYPE_EFFECTSOUT``
+	  - Omitted for now
+	* - ``V4L2_BUF_TYPE_VIDEOOUT``
+	  - ``V4L2_BUF_TYPE_VIDEO_OUTPUT``
+	* - ``-``
+	  - ``V4L2_BUF_TYPE_VIDEO_OVERLAY``
+	* - ``-``
+	  - ``V4L2_BUF_TYPE_VBI_CAPTURE``
+	* - ``-``
+	  - ``V4L2_BUF_TYPE_VBI_OUTPUT``
+	* - ``-``
+	  - ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE``
+	* - ``-``
+	  - ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``
+	* - ``V4L2_BUF_TYPE_PRIVATE_BASE``
+	  - ``V4L2_BUF_TYPE_PRIVATE`` (but this is deprecated)
+
+
+10. In struct :c:type:`v4l2_fmtdesc` a enum
+    :c:type:`v4l2_buf_type` field named ``type`` was
+    added as in struct :c:type:`v4l2_format`. The
+    ``VIDIOC_ENUM_FBUFFMT`` ioctl is no longer needed and was removed.
+    These calls can be replaced by
+    :ref:`VIDIOC_ENUM_FMT` with type
+    ``V4L2_BUF_TYPE_VIDEO_OVERLAY``.
+
+11. In struct :c:type:`v4l2_pix_format` the ``depth``
+    field was removed, assuming applications which recognize the format
+    by its four-character-code already know the color depth, and others
+    do not care about it. The same rationale lead to the removal of the
+    ``V4L2_FMT_FLAG_COMPRESSED`` flag. The
+    ``V4L2_FMT_FLAG_SWCONVECOMPRESSED`` flag was removed because drivers
+    are not supposed to convert images in kernel space. A user library
+    of conversion functions should be provided instead. The
+    ``V4L2_FMT_FLAG_BYTESPERLINE`` flag was redundant. Applications can
+    set the ``bytesperline`` field to zero to get a reasonable default.
+    Since the remaining flags were replaced as well, the ``flags`` field
+    itself was removed.
+
+    The interlace flags were replaced by a enum
+    :c:type:`v4l2_field` value in a newly added ``field``
+    field.
+
+
+
+    .. flat-table::
+	:header-rows:  1
+	:stub-columns: 0
+
+	* - Old flag
+	  - enum :c:type:`v4l2_field`
+	* - ``V4L2_FMT_FLAG_NOT_INTERLACED``
+	  - ?
+	* - ``V4L2_FMT_FLAG_INTERLACED`` = ``V4L2_FMT_FLAG_COMBINED``
+	  - ``V4L2_FIELD_INTERLACED``
+	* - ``V4L2_FMT_FLAG_TOPFIELD`` = ``V4L2_FMT_FLAG_ODDFIELD``
+	  - ``V4L2_FIELD_TOP``
+	* - ``V4L2_FMT_FLAG_BOTFIELD`` = ``V4L2_FMT_FLAG_EVENFIELD``
+	  - ``V4L2_FIELD_BOTTOM``
+	* - ``-``
+	  - ``V4L2_FIELD_SEQ_TB``
+	* - ``-``
+	  - ``V4L2_FIELD_SEQ_BT``
+	* - ``-``
+	  - ``V4L2_FIELD_ALTERNATE``
+
+
+    The color space flags were replaced by a enum
+    :c:type:`v4l2_colorspace` value in a newly added
+    ``colorspace`` field, where one of ``V4L2_COLORSPACE_SMPTE170M``,
+    ``V4L2_COLORSPACE_BT878``, ``V4L2_COLORSPACE_470_SYSTEM_M`` or
+    ``V4L2_COLORSPACE_470_SYSTEM_BG`` replaces ``V4L2_FMT_CS_601YUV``.
+
+12. In struct :c:type:`v4l2_requestbuffers` the
+    ``type`` field was properly defined as enum
+    :c:type:`v4l2_buf_type`. Buffer types changed as
+    mentioned above. A new ``memory`` field of type enum
+    :c:type:`v4l2_memory` was added to distinguish between
+    I/O methods using buffers allocated by the driver or the
+    application. See :ref:`io` for details.
+
+13. In struct :c:type:`v4l2_buffer` the ``type`` field was
+    properly defined as enum :c:type:`v4l2_buf_type`.
+    Buffer types changed as mentioned above. A ``field`` field of type
+    enum :c:type:`v4l2_field` was added to indicate if a
+    buffer contains a top or bottom field. The old field flags were
+    removed. Since no unadjusted system time clock was added to the
+    kernel as planned, the ``timestamp`` field changed back from type
+    stamp_t, an unsigned 64 bit integer expressing the sample time in
+    nanoseconds, to struct :c:type:`timeval`. With the addition
+    of a second memory mapping method the ``offset`` field moved into
+    union ``m``, and a new ``memory`` field of type enum
+    :c:type:`v4l2_memory` was added to distinguish between
+    I/O methods. See :ref:`io` for details.
+
+    The ``V4L2_BUF_REQ_CONTIG`` flag was used by the V4L compatibility
+    layer, after changes to this code it was no longer needed. The
+    ``V4L2_BUF_ATTR_DEVICEMEM`` flag would indicate if the buffer was
+    indeed allocated in device memory rather than DMA-able system
+    memory. It was barely useful and so was removed.
+
+14. In struct :c:type:`v4l2_framebuffer` the
+    ``base[3]`` array anticipating double- and triple-buffering in
+    off-screen video memory, however without defining a synchronization
+    mechanism, was replaced by a single pointer. The
+    ``V4L2_FBUF_CAP_SCALEUP`` and ``V4L2_FBUF_CAP_SCALEDOWN`` flags were
+    removed. Applications can determine this capability more accurately
+    using the new cropping and scaling interface. The
+    ``V4L2_FBUF_CAP_CLIPPING`` flag was replaced by
+    ``V4L2_FBUF_CAP_LIST_CLIPPING`` and
+    ``V4L2_FBUF_CAP_BITMAP_CLIPPING``.
+
+15. In struct :c:type:`v4l2_clip` the ``x``, ``y``,
+    ``width`` and ``height`` field moved into a ``c`` substructure of
+    type struct :c:type:`v4l2_rect`. The ``x`` and ``y``
+    fields were renamed to ``left`` and ``top``, i. e. offsets to a
+    context dependent origin.
+
+16. In struct :c:type:`v4l2_window` the ``x``, ``y``,
+    ``width`` and ``height`` field moved into a ``w`` substructure as
+    above. A ``field`` field of type :c:type:`v4l2_field` was added to
+    distinguish between field and frame (interlaced) overlay.
+
+17. The digital zoom interface, including struct
+    struct ``v4l2_zoomcap``, struct
+    struct ``v4l2_zoom``, ``V4L2_ZOOM_NONCAP`` and
+    ``V4L2_ZOOM_WHILESTREAMING`` was replaced by a new cropping and
+    scaling interface. The previously unused struct
+    struct :c:type:`v4l2_cropcap` and struct :c:type:`v4l2_crop`
+    where redefined for this purpose. See :ref:`crop` for details.
+
+18. In struct :c:type:`v4l2_vbi_format` the
+    ``SAMPLE_FORMAT`` field now contains a four-character-code as used
+    to identify video image formats and ``V4L2_PIX_FMT_GREY`` replaces
+    the ``V4L2_VBI_SF_UBYTE`` define. The ``reserved`` field was
+    extended.
+
+19. In struct :c:type:`v4l2_captureparm` the type of
+    the ``timeperframe`` field changed from unsigned long to struct
+    :c:type:`v4l2_fract`. This allows the accurate
+    expression of multiples of the NTSC-M frame rate 30000 / 1001. A new
+    field ``readbuffers`` was added to control the driver behaviour in
+    read I/O mode.
+
+    Similar changes were made to struct
+    :c:type:`v4l2_outputparm`.
+
+20. The struct ``v4l2_performance`` and
+    ``VIDIOC_G_PERF`` ioctl were dropped. Except when using the
+    :ref:`read/write I/O method <rw>`, which is limited anyway, this
+    information is already available to applications.
+
+21. The example transformation from RGB to YCbCr color space in the old
+    V4L2 documentation was inaccurate, this has been corrected in
+    :ref:`pixfmt`.
+
+
+V4L2 2003-06-19
+===============
+
+1. A new capability flag ``V4L2_CAP_RADIO`` was added for radio devices.
+   Prior to this change radio devices would identify solely by having
+   exactly one tuner whose type field reads ``V4L2_TUNER_RADIO``.
+
+2. An optional driver access priority mechanism was added, see
+   :ref:`app-pri` for details.
+
+3. The audio input and output interface was found to be incomplete.
+
+   Previously the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl would
+   enumerate the available audio inputs. An ioctl to determine the
+   current audio input, if more than one combines with the current video
+   input, did not exist. So ``VIDIOC_G_AUDIO`` was renamed to
+   ``VIDIOC_G_AUDIO_OLD``, this ioctl was removed on Kernel 2.6.39. The
+   :ref:`VIDIOC_ENUMAUDIO` ioctl was added to
+   enumerate audio inputs, while
+   :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` now reports the current
+   audio input.
+
+   The same changes were made to
+   :ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` and
+   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>`.
+
+   Until further the "videodev" module will automatically translate
+   between the old and new ioctls, but drivers and applications must be
+   updated to successfully compile again.
+
+4. The :ref:`VIDIOC_OVERLAY` ioctl was incorrectly
+   defined with write-read parameter. It was changed to write-only,
+   while the write-read version was renamed to ``VIDIOC_OVERLAY_OLD``.
+   The old ioctl was removed on Kernel 2.6.39. Until further the
+   "videodev" kernel module will automatically translate to the new
+   version, so drivers must be recompiled, but not applications.
+
+5. :ref:`overlay` incorrectly stated that clipping rectangles define
+   regions where the video can be seen. Correct is that clipping
+   rectangles define regions where *no* video shall be displayed and so
+   the graphics surface can be seen.
+
+6. The :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` and
+   :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls were defined with
+   write-only parameter, inconsistent with other ioctls modifying their
+   argument. They were changed to write-read, while a ``_OLD`` suffix
+   was added to the write-only versions. The old ioctls were removed on
+   Kernel 2.6.39. Drivers and applications assuming a constant parameter
+   need an update.
+
+
+V4L2 2003-11-05
+===============
+
+1. In :ref:`pixfmt-rgb` the following pixel formats were incorrectly
+   transferred from Bill Dirks' V4L2 specification. Descriptions below
+   refer to bytes in memory, in ascending address order.
+
+
+
+   .. flat-table::
+       :header-rows:  1
+       :stub-columns: 0
+
+       * - Symbol

+	 - R, G, B, X
+	 - B, G, R, X
+
+
+   The ``V4L2_PIX_FMT_BGR24`` example was always correct.
+
+   In :ref:`v4l-image-properties` the mapping of the V4L
+   ``VIDEO_PALETTE_RGB24`` and ``VIDEO_PALETTE_RGB32`` formats to V4L2
+   pixel formats was accordingly corrected.
+
+2. Unrelated to the fixes above, drivers may still interpret some V4L2
+   RGB pixel formats differently. These issues have yet to be addressed,
+   for details see :ref:`pixfmt-rgb`.
+
+
+V4L2 in Linux 2.6.6, 2004-05-09
+===============================
+
+1. The :ref:`VIDIOC_CROPCAP` ioctl was incorrectly
+   defined with read-only parameter. It is now defined as write-read
+   ioctl, while the read-only version was renamed to
+   ``VIDIOC_CROPCAP_OLD``. The old ioctl was removed on Kernel 2.6.39.
+
+
+V4L2 in Linux 2.6.8
+===================
+
+1. A new field ``input`` (former ``reserved[0]``) was added to the
+   struct :c:type:`v4l2_buffer` structure. Purpose of this
+   field is to alternate between video inputs (e. g. cameras) in step
+   with the video capturing process. This function must be enabled with
+   the new ``V4L2_BUF_FLAG_INPUT`` flag. The ``flags`` field is no
+   longer read-only.
+
+
+V4L2 spec erratum 2004-08-01
+============================
+
+1. The return value of the :ref:`func-open` function was incorrectly
+   documented.
+
+2. Audio output ioctls end in -AUDOUT, not -AUDIOOUT.
+
+3. In the Current Audio Input example the ``VIDIOC_G_AUDIO`` ioctl took
+   the wrong argument.
+
+4. The documentation of the :ref:`VIDIOC_QBUF` and
+   :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctls did not mention the
+   struct :c:type:`v4l2_buffer` ``memory`` field. It was
+   also missing from examples. Also on the ``VIDIOC_DQBUF`` page the ``EIO``
+   error code was not documented.
+
+
+V4L2 in Linux 2.6.14
+====================
+
+1. A new sliced VBI interface was added. It is documented in
+   :ref:`sliced` and replaces the interface first proposed in V4L2
+   specification 0.8.
+
+
+V4L2 in Linux 2.6.15
+====================
+
+1. The :ref:`VIDIOC_LOG_STATUS` ioctl was added.
+
+2. New video standards ``V4L2_STD_NTSC_443``, ``V4L2_STD_SECAM_LC``,
+   ``V4L2_STD_SECAM_DK`` (a set of SECAM D, K and K1), and
+   ``V4L2_STD_ATSC`` (a set of ``V4L2_STD_ATSC_8_VSB`` and
+   ``V4L2_STD_ATSC_16_VSB``) were defined. Note the ``V4L2_STD_525_60``
+   set now includes ``V4L2_STD_NTSC_443``. See also
+   :ref:`v4l2-std-id`.
+
+3. The ``VIDIOC_G_COMP`` and ``VIDIOC_S_COMP`` ioctl were renamed to
+   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` respectively. Their
+   argument was replaced by a struct
+   ``v4l2_mpeg_compression`` pointer. (The
+   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls where removed
+   in Linux 2.6.25.)
+
+
+V4L2 spec erratum 2005-11-27
+============================
+
+The capture example in :ref:`capture-example` called the
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl without checking if
+cropping is supported. In the video standard selection example in
+:ref:`standard` the :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` call used
+the wrong argument type.
+
+
+V4L2 spec erratum 2006-01-10
+============================
+
+1. The ``V4L2_IN_ST_COLOR_KILL`` flag in struct
+   :c:type:`v4l2_input` not only indicates if the color
+   killer is enabled, but also if it is active. (The color killer
+   disables color decoding when it detects no color in the video signal
+   to improve the image quality.)
+
+2. :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` is a write-read ioctl, not
+   write-only as stated on its reference page. The ioctl changed in 2003
+   as noted above.
+
+
+V4L2 spec erratum 2006-02-03
+============================
+
+1. In struct :c:type:`v4l2_captureparm` and struct
+   :c:type:`v4l2_outputparm` the ``timeperframe``
+   field gives the time in seconds, not microseconds.
+
+
+V4L2 spec erratum 2006-02-04
+============================
+
+1. The ``clips`` field in struct :c:type:`v4l2_window`
+   must point to an array of struct :c:type:`v4l2_clip`, not
+   a linked list, because drivers ignore the struct
+   struct :c:type:`v4l2_clip`. ``next`` pointer.
+
+
+V4L2 in Linux 2.6.17
+====================
+
+1. New video standard macros were added: ``V4L2_STD_NTSC_M_KR`` (NTSC M
+   South Korea), and the sets ``V4L2_STD_MN``, ``V4L2_STD_B``,
+   ``V4L2_STD_GH`` and ``V4L2_STD_DK``. The ``V4L2_STD_NTSC`` and
+   ``V4L2_STD_SECAM`` sets now include ``V4L2_STD_NTSC_M_KR`` and
+   ``V4L2_STD_SECAM_LC`` respectively.
+
+2. A new ``V4L2_TUNER_MODE_LANG1_LANG2`` was defined to record both
+   languages of a bilingual program. The use of
+   ``V4L2_TUNER_MODE_STEREO`` for this purpose is deprecated now. See
+   the :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` section for details.
+
+
+V4L2 spec erratum 2006-09-23 (Draft 0.15)
+=========================================
+
+1. In various places ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` and
+   ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT`` of the sliced VBI interface were
+   not mentioned along with other buffer types.
+
+2. In :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` it was clarified that the struct
+   :c:type:`v4l2_audio` ``mode`` field is a flags field.
+
+3. :ref:`VIDIOC_QUERYCAP` did not mention the sliced VBI and radio
+   capability flags.
+
+4. In :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` it was clarified that applications
+   must initialize the tuner ``type`` field of struct
+   :c:type:`v4l2_frequency` before calling
+   :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`.
+
+5. The ``reserved`` array in struct
+   :c:type:`v4l2_requestbuffers` has 2 elements,
+   not 32.
+
+6. In :ref:`output` and :ref:`raw-vbi` the device file names
+   ``/dev/vout`` which never caught on were replaced by ``/dev/video``.
+
+7. With Linux 2.6.15 the possible range for VBI device minor numbers was
+   extended from 224-239 to 224-255. Accordingly device file names
+   ``/dev/vbi0`` to ``/dev/vbi31`` are possible now.
+
+
+V4L2 in Linux 2.6.18
+====================
+
+1. New ioctls :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+   :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+   :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` were added, a
+   flag to skip unsupported controls with
+   :ref:`VIDIOC_QUERYCTRL`, new control types
+   ``V4L2_CTRL_TYPE_INTEGER64`` and ``V4L2_CTRL_TYPE_CTRL_CLASS``
+   (:c:type:`v4l2_ctrl_type`), and new control flags
+   ``V4L2_CTRL_FLAG_READ_ONLY``, ``V4L2_CTRL_FLAG_UPDATE``,
+   ``V4L2_CTRL_FLAG_INACTIVE`` and ``V4L2_CTRL_FLAG_SLIDER``
+   (:ref:`control-flags`). See :ref:`extended-controls` for details.
+
+
+V4L2 in Linux 2.6.19
+====================
+
+1. In struct :c:type:`v4l2_sliced_vbi_cap` a
+   buffer type field was added replacing a reserved field. Note on
+   architectures where the size of enum types differs from int types the
+   size of the structure changed. The
+   :ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl
+   was redefined from being read-only to write-read. Applications must
+   initialize the type field and clear the reserved fields now. These
+   changes may *break the compatibility* with older drivers and
+   applications.
+
+2. The ioctls :ref:`VIDIOC_ENUM_FRAMESIZES`
+   and
+   :ref:`VIDIOC_ENUM_FRAMEINTERVALS`
+   were added.
+
+3. A new pixel format ``V4L2_PIX_FMT_RGB444`` (:ref:`pixfmt-rgb`) was
+   added.
+
+
+V4L2 spec erratum 2006-10-12 (Draft 0.17)
+=========================================
+
+1. ``V4L2_PIX_FMT_HM12`` (:ref:`reserved-formats`) is a YUV 4:2:0, not
+   4:2:2 format.
+
+
+V4L2 in Linux 2.6.21
+====================
+
+1. The ``videodev2.h`` header file is now dual licensed under GNU
+   General Public License version two or later, and under a 3-clause
+   BSD-style license.
+
+
+V4L2 in Linux 2.6.22
+====================
+
+1. Two new field orders ``V4L2_FIELD_INTERLACED_TB`` and
+   ``V4L2_FIELD_INTERLACED_BT`` were added. See :c:type:`v4l2_field` for
+   details.
+
+2. Three new clipping/blending methods with a global or straight or
+   inverted local alpha value were added to the video overlay interface.
+   See the description of the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+   and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls for details.
+
+   A new ``global_alpha`` field was added to
+   :c:type:`v4l2_window`, extending the structure. This
+   may *break compatibility* with applications using a struct
+   struct :c:type:`v4l2_window` directly. However the
+   :ref:`VIDIOC_G/S/TRY_FMT <VIDIOC_G_FMT>` ioctls, which take a
+   pointer to a :c:type:`v4l2_format` parent structure
+   with padding bytes at the end, are not affected.
+
+3. The format of the ``chromakey`` field in struct
+   :c:type:`v4l2_window` changed from "host order RGB32"
+   to a pixel value in the same format as the framebuffer. This may
+   *break compatibility* with existing applications. Drivers supporting
+   the "host order RGB32" format are not known.
+
+
+V4L2 in Linux 2.6.24
+====================
+
+1. The pixel formats ``V4L2_PIX_FMT_PAL8``, ``V4L2_PIX_FMT_YUV444``,
+   ``V4L2_PIX_FMT_YUV555``, ``V4L2_PIX_FMT_YUV565`` and
+   ``V4L2_PIX_FMT_YUV32`` were added.
+
+
+V4L2 in Linux 2.6.25
+====================
+
+1. The pixel formats :ref:`V4L2_PIX_FMT_Y16 <V4L2-PIX-FMT-Y16>` and
+   :ref:`V4L2_PIX_FMT_SBGGR16 <V4L2-PIX-FMT-SBGGR16>` were added.
+
+2. New :ref:`controls <control>` ``V4L2_CID_POWER_LINE_FREQUENCY``,
+   ``V4L2_CID_HUE_AUTO``, ``V4L2_CID_WHITE_BALANCE_TEMPERATURE``,
+   ``V4L2_CID_SHARPNESS`` and ``V4L2_CID_BACKLIGHT_COMPENSATION`` were
+   added. The controls ``V4L2_CID_BLACK_LEVEL``, ``V4L2_CID_WHITENESS``,
+   ``V4L2_CID_HCENTER`` and ``V4L2_CID_VCENTER`` were deprecated.
+
+3. A :ref:`Camera controls class <camera-controls>` was added, with
+   the new controls ``V4L2_CID_EXPOSURE_AUTO``,
+   ``V4L2_CID_EXPOSURE_ABSOLUTE``, ``V4L2_CID_EXPOSURE_AUTO_PRIORITY``,
+   ``V4L2_CID_PAN_RELATIVE``, ``V4L2_CID_TILT_RELATIVE``,
+   ``V4L2_CID_PAN_RESET``, ``V4L2_CID_TILT_RESET``,
+   ``V4L2_CID_PAN_ABSOLUTE``, ``V4L2_CID_TILT_ABSOLUTE``,
+   ``V4L2_CID_FOCUS_ABSOLUTE``, ``V4L2_CID_FOCUS_RELATIVE`` and
+   ``V4L2_CID_FOCUS_AUTO``.
+
+4. The ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls, which
+   were superseded by the :ref:`extended controls <extended-controls>`
+   interface in Linux 2.6.18, where finally removed from the
+   ``videodev2.h`` header file.
+
+
+V4L2 in Linux 2.6.26
+====================
+
+1. The pixel formats ``V4L2_PIX_FMT_Y16`` and ``V4L2_PIX_FMT_SBGGR16``
+   were added.
+
+2. Added user controls ``V4L2_CID_CHROMA_AGC`` and
+   ``V4L2_CID_COLOR_KILLER``.
+
+
+V4L2 in Linux 2.6.27
+====================
+
+1. The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl
+   and the ``V4L2_CAP_HW_FREQ_SEEK`` capability were added.
+
+2. The pixel formats ``V4L2_PIX_FMT_YVYU``, ``V4L2_PIX_FMT_PCA501``,
+   ``V4L2_PIX_FMT_PCA505``, ``V4L2_PIX_FMT_PCA508``,
+   ``V4L2_PIX_FMT_PCA561``, ``V4L2_PIX_FMT_SGBRG8``,
+   ``V4L2_PIX_FMT_PAC207`` and ``V4L2_PIX_FMT_PJPG`` were added.
+
+
+V4L2 in Linux 2.6.28
+====================
+
+1. Added ``V4L2_MPEG_AUDIO_ENCODING_AAC`` and
+   ``V4L2_MPEG_AUDIO_ENCODING_AC3`` MPEG audio encodings.
+
+2. Added ``V4L2_MPEG_VIDEO_ENCODING_MPEG_4_AVC`` MPEG video encoding.
+
+3. The pixel formats ``V4L2_PIX_FMT_SGRBG10`` and
+   ``V4L2_PIX_FMT_SGRBG10DPCM8`` were added.
+
+
+V4L2 in Linux 2.6.29
+====================
+
+1. The ``VIDIOC_G_CHIP_IDENT`` ioctl was renamed to
+   ``VIDIOC_G_CHIP_IDENT_OLD`` and ``VIDIOC_DBG_G_CHIP_IDENT`` was
+   introduced in its place. The old struct
+   struct ``v4l2_chip_ident`` was renamed to
+   struct ``v4l2_chip_ident_old``.
+
+2. The pixel formats ``V4L2_PIX_FMT_VYUY``, ``V4L2_PIX_FMT_NV16`` and
+   ``V4L2_PIX_FMT_NV61`` were added.
+
+3. Added camera controls ``V4L2_CID_ZOOM_ABSOLUTE``,
+   ``V4L2_CID_ZOOM_RELATIVE``, ``V4L2_CID_ZOOM_CONTINUOUS`` and
+   ``V4L2_CID_PRIVACY``.
+
+
+V4L2 in Linux 2.6.30
+====================
+
+1. New control flag ``V4L2_CTRL_FLAG_WRITE_ONLY`` was added.
+
+2. New control ``V4L2_CID_COLORFX`` was added.
+
+
+V4L2 in Linux 2.6.32
+====================
+
+1. In order to be easier to compare a V4L2 API and a kernel version, now
+   V4L2 API is numbered using the Linux Kernel version numeration.
+
+2. Finalized the RDS capture API. See :ref:`rds` for more information.
+
+3. Added new capabilities for modulators and RDS encoders.
+
+4. Add description for libv4l API.
+
+5. Added support for string controls via new type
+   ``V4L2_CTRL_TYPE_STRING``.
+
+6. Added ``V4L2_CID_BAND_STOP_FILTER`` documentation.
+
+7. Added FM Modulator (FM TX) Extended Control Class:
+   ``V4L2_CTRL_CLASS_FM_TX`` and their Control IDs.
+
+8. Added FM Receiver (FM RX) Extended Control Class:
+   ``V4L2_CTRL_CLASS_FM_RX`` and their Control IDs.
+
+9. Added Remote Controller chapter, describing the default Remote
+   Controller mapping for media devices.
+
+
+V4L2 in Linux 2.6.33
+====================
+
+1. Added support for Digital Video timings in order to support HDTV
+   receivers and transmitters.
+
+
+V4L2 in Linux 2.6.34
+====================
+
+1. Added ``V4L2_CID_IRIS_ABSOLUTE`` and ``V4L2_CID_IRIS_RELATIVE``
+   controls to the :ref:`Camera controls class <camera-controls>`.
+
+
+V4L2 in Linux 2.6.37
+====================
+
+1. Remove the vtx (videotext/teletext) API. This API was no longer used
+   and no hardware exists to verify the API. Nor were any userspace
+   applications found that used it. It was originally scheduled for
+   removal in 2.6.35.
+
+
+V4L2 in Linux 2.6.39
+====================
+
+1. The old VIDIOC_*_OLD symbols and V4L1 support were removed.
+
+2. Multi-planar API added. Does not affect the compatibility of current
+   drivers and applications. See :ref:`multi-planar API <planar-apis>`
+   for details.
+
+
+V4L2 in Linux 3.1
+=================
+
+1. VIDIOC_QUERYCAP now returns a per-subsystem version instead of a
+   per-driver one.
+
+   Standardize an error code for invalid ioctl.
+
+   Added V4L2_CTRL_TYPE_BITMASK.
+
+
+V4L2 in Linux 3.2
+=================
+
+1. V4L2_CTRL_FLAG_VOLATILE was added to signal volatile controls to
+   userspace.
+
+2. Add selection API for extended control over cropping and composing.
+   Does not affect the compatibility of current drivers and
+   applications. See :ref:`selection API <selection-api>` for details.
+
+
+V4L2 in Linux 3.3
+=================
+
+1. Added ``V4L2_CID_ALPHA_COMPONENT`` control to the
+   :ref:`User controls class <control>`.
+
+2. Added the device_caps field to struct v4l2_capabilities and added
+   the new V4L2_CAP_DEVICE_CAPS capability.
+
+
+V4L2 in Linux 3.4
+=================
+
+1. Added :ref:`JPEG compression control class <jpeg-controls>`.
+
+2. Extended the DV Timings API:

+
+
+.. _other:
+
+Relation of V4L2 to other Linux multimedia APIs
+===============================================
+
+
+.. _xvideo:
+
+X Video Extension
+-----------------
+
+The X Video Extension (abbreviated XVideo or just Xv) is an extension of
+the X Window system, implemented for example by the XFree86 project. Its
+scope is similar to V4L2, an API to video capture and output devices for
+X clients. Xv allows applications to display live video in a window,
+send window contents to a TV output, and capture or output still images
+in XPixmaps [#f1]_. With their implementation XFree86 makes the extension
+available across many operating systems and architectures.
+
+Because the driver is embedded into the X server Xv has a number of
+advantages over the V4L2 :ref:`video overlay interface <overlay>`. The
+driver can easily determine the overlay target, i. e. visible graphics
+memory or off-screen buffers for a destructive overlay. It can program
+the RAMDAC for a non-destructive overlay, scaling or color-keying, or
+the clipping functions of the video capture hardware, always in sync
+with drawing operations or windows moving or changing their stacking
+order.
+
+To combine the advantages of Xv and V4L a special Xv driver exists in
+XFree86 and XOrg, just programming any overlay capable Video4Linux
+device it finds. To enable it ``/etc/X11/XF86Config`` must contain these
+lines:
+
+::
+
+    Section "Module"
+	Load "v4l"
+    EndSection
+
+As of XFree86 4.2 this driver still supports only V4L ioctls, however it
+should work just fine with all V4L2 devices through the V4L2
+backward-compatibility layer. Since V4L2 permits multiple opens it is
+possible (if supported by the V4L2 driver) to capture video while an X
+client requested video overlay. Restrictions of simultaneous capturing
+and overlay are discussed in :ref:`overlay` apply.
+
+Only marginally related to V4L2, XFree86 extended Xv to support hardware
+YUV to RGB conversion and scaling for faster video playback, and added
+an interface to MPEG-2 decoding hardware. This API is useful to display
+images captured with V4L2 devices.
+
+
+Digital Video
+-------------
+
+V4L2 does not support digital terrestrial, cable or satellite broadcast.
+A separate project aiming at digital receivers exists. You can find its
+homepage at `https://linuxtv.org <https://linuxtv.org>`__. The Linux
+DVB API has no connection to the V4L2 API except that drivers for hybrid
+hardware may support both.

+Input/Output
+############
+The V4L2 API defines several different methods to read from or write to
+a device. All drivers exchanging data with applications must support at
+least one of them.
+
+The classic I/O method using the :ref:`read() <func-read>` and
+:ref:`write() <func-write>` function is automatically selected after opening a
+V4L2 device. When the driver does not support this method attempts to
+read or write will fail at any time.
+
+Other methods must be negotiated. To select the streaming I/O method
+with memory mapped or user buffers applications call the
+:ref:`VIDIOC_REQBUFS` ioctl. The asynchronous I/O
+method is not defined yet.
+
+Video overlay can be considered another I/O method, although the
+application does not directly receive the image data. It is selected by
+initiating video overlay with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl. For more information see :ref:`overlay`.
+
+Generally exactly one I/O method, including overlay, is associated with
+each file descriptor. The only exceptions are applications not
+exchanging data with a driver ("panel applications", see :ref:`open`)
+and drivers permitting simultaneous video capturing and overlay using
+the same file descriptor, for compatibility with V4L and earlier
+versions of V4L2.
+
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_REQBUFS` would permit this to some
+degree, but for simplicity drivers need not support switching the I/O
+method (after first switching away from read/write) other than by
+closing and reopening the device.

+************
+Introduction
+************
+
+libv4l is a collection of libraries which adds a thin abstraction layer
+on top of video4linux2 devices. The purpose of this (thin) layer is to
+make it easy for application writers to support a wide variety of
+devices without having to write separate code for different devices in
+the same class.
+
+An example of using libv4l is provided by
+:ref:`v4l2grab <v4l2grab-example>`.
+
+libv4l consists of 3 different libraries:
+
+
+libv4lconvert
+=============
+
+libv4lconvert is a library that converts several different pixelformats
+found in V4L2 drivers into a few common RGB and YUY formats.
+
+It currently accepts the following V4L2 driver formats:
+:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
+:ref:`V4L2_PIX_FMT_HM12 <V4L2-PIX-FMT-HM12>`,
+:ref:`V4L2_PIX_FMT_JPEG <V4L2-PIX-FMT-JPEG>`,
+:ref:`V4L2_PIX_FMT_MJPEG <V4L2-PIX-FMT-MJPEG>`,
+:ref:`V4L2_PIX_FMT_MR97310A <V4L2-PIX-FMT-MR97310A>`,
+:ref:`V4L2_PIX_FMT_OV511 <V4L2-PIX-FMT-OV511>`,
+:ref:`V4L2_PIX_FMT_OV518 <V4L2-PIX-FMT-OV518>`,
+:ref:`V4L2_PIX_FMT_PAC207 <V4L2-PIX-FMT-PAC207>`,
+:ref:`V4L2_PIX_FMT_PJPG <V4L2-PIX-FMT-PJPG>`,
+:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
+:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`,
+:ref:`V4L2_PIX_FMT_SGBRG8 <V4L2-PIX-FMT-SGBRG8>`,
+:ref:`V4L2_PIX_FMT_SGRBG8 <V4L2-PIX-FMT-SGRBG8>`,
+:ref:`V4L2_PIX_FMT_SN9C10X <V4L2-PIX-FMT-SN9C10X>`,
+:ref:`V4L2_PIX_FMT_SN9C20X_I420 <V4L2-PIX-FMT-SN9C20X-I420>`,
+:ref:`V4L2_PIX_FMT_SPCA501 <V4L2-PIX-FMT-SPCA501>`,
+:ref:`V4L2_PIX_FMT_SPCA505 <V4L2-PIX-FMT-SPCA505>`,
+:ref:`V4L2_PIX_FMT_SPCA508 <V4L2-PIX-FMT-SPCA508>`,
+:ref:`V4L2_PIX_FMT_SPCA561 <V4L2-PIX-FMT-SPCA561>`,
+:ref:`V4L2_PIX_FMT_SQ905C <V4L2-PIX-FMT-SQ905C>`,
+:ref:`V4L2_PIX_FMT_SRGGB8 <V4L2-PIX-FMT-SRGGB8>`,
+:ref:`V4L2_PIX_FMT_UYVY <V4L2-PIX-FMT-UYVY>`,
+:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`,
+:ref:`V4L2_PIX_FMT_YUYV <V4L2-PIX-FMT-YUYV>`,
+:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, and
+:ref:`V4L2_PIX_FMT_YVYU <V4L2-PIX-FMT-YVYU>`.
+
+Later on libv4lconvert was expanded to also be able to do various video
+processing functions to improve webcam video quality. The video
+processing is split in to 2 parts: libv4lconvert/control and
+libv4lconvert/processing.
+
+The control part is used to offer video controls which can be used to
+control the video processing functions made available by
+libv4lconvert/processing. These controls are stored application wide
+(until reboot) by using a persistent shared memory object.
+
+libv4lconvert/processing offers the actual video processing
+functionality.
+
+
+libv4l1
+=======
+
+This library offers functions that can be used to quickly make v4l1
+applications work with v4l2 devices. These functions work exactly like
+the normal open/close/etc, except that libv4l1 does full emulation of
+the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it will
+just pass calls through.
+
+Since those functions are emulations of the old V4L1 API, it shouldn't
+be used for new applications.
+
+
+libv4l2
+=======
+
+This library should be used for all modern V4L2 applications.
+
+It provides handles to call V4L2 open/ioctl/close/poll methods. Instead
+of just providing the raw output of the device, it enhances the calls in
+the sense that it will use libv4lconvert to provide more video formats
+and to enhance the image quality.
+
+In most cases, libv4l2 just passes the calls directly through to the
+v4l2 driver, intercepting the calls to
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_ENUM_FRAMESIZES <VIDIOC_ENUM_FRAMESIZES>` and
+:ref:`VIDIOC_ENUM_FRAMEINTERVALS <VIDIOC_ENUM_FRAMEINTERVALS>` in
+order to emulate the formats
+:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
+:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
+:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`, and
+:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, if they aren't
+available in the driver. :ref:`VIDIOC_ENUM_FMT <VIDIOC_ENUM_FMT>`
+keeps enumerating the hardware supported formats, plus the emulated
+formats offered by libv4l at the end.
+
+
+.. _libv4l-ops:
+
+Libv4l device control functions
+-------------------------------
+
+The common file operation methods are provided by libv4l.
+
+Those functions operate just like the gcc function ``dup()`` and
+V4L2 functions
+:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
+:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`read() <v4l2-read>`,
+:c:func:`mmap() <v4l2-mmap>` and :c:func:`munmap() <v4l2-munmap>`:
+
+.. c:function:: int v4l2_open(const char *file, int oflag, ...)
+
+   operates like the :c:func:`open() <v4l2-open>` function.
+
+.. c:function:: int v4l2_close(int fd)
+
+   operates like the :c:func:`close() <v4l2-close>` function.
+
+.. c:function:: int v4l2_dup(int fd)
+
+   operates like the libc ``dup()`` function, duplicating a file handler.
+
+.. c:function:: int v4l2_ioctl (int fd, unsigned long int request, ...)
+
+   operates like the :c:func:`ioctl() <v4l2-ioctl>` function.
+
+.. c:function:: int v4l2_read (int fd, void* buffer, size_t n)
+
+   operates like the :c:func:`read() <v4l2-read>` function.
+
+.. c:function:: void v4l2_mmap(void *start, size_t length, int prot, int flags, int fd, int64_t offset);
+
+   operates like the :c:func:`munmap() <v4l2-munmap>` function.
+
+.. c:function:: int v4l2_munmap(void *_start, size_t length);
+
+   operates like the :c:func:`munmap() <v4l2-munmap>` function.
+
+Those functions provide additional control:
+
+.. c:function:: int v4l2_fd_open(int fd, int v4l2_flags)
+
+   opens an already opened fd for further use through v4l2lib and possibly
+   modify libv4l2's default behavior through the ``v4l2_flags`` argument.
+   Currently, ``v4l2_flags`` can be ``V4L2_DISABLE_CONVERSION``, to disable
+   format conversion.
+
+.. c:function:: int v4l2_set_control(int fd, int cid, int value)
+
+   This function takes a value of 0 - 65535, and then scales that range to the
+   actual range of the given v4l control id, and then if the cid exists and is
+   not locked sets the cid to the scaled value.
+
+.. c:function:: int v4l2_get_control(int fd, int cid)
+
+   This function returns a value of 0 - 65535, scaled to from the actual range
+   of the given v4l control id. when the cid does not exist, could not be
+   accessed for some reason, or some error occurred 0 is returned.
+
+
+v4l1compat.so wrapper library
+=============================
+
+This library intercepts calls to
+:c:func:`open() <v4l2-open>`, :c:func:`close() <v4l2-close>`,
+:c:func:`ioctl() <v4l2-ioctl>`, :c:func:`mmap() <v4l2-mmap>` and
+:c:func:`munmap() <v4l2-munmap>`
+operations and redirects them to the libv4l counterparts, by using
+``LD_PRELOAD=/usr/lib/v4l1compat.so``. It also emulates V4L1 calls via V4L2
+API.
+
+It allows usage of binary legacy applications that still don't use
+libv4l.

+******************************
+Streaming I/O (Memory Mapping)
+******************************
+
+Input and output devices support this I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set. There are two
+streaming methods, to determine if the memory mapping flavor is
+supported applications must call the :ref:`VIDIOC_REQBUFS` ioctl
+with the memory type set to ``V4L2_MEMORY_MMAP``.
+
+Streaming is an I/O method where only pointers to buffers are exchanged
+between application and driver, the data itself is not copied. Memory
+mapping is primarily intended to map buffers in device memory into the
+application's address space. Device memory can be for example the video
+memory on a graphics card with a video capture add-on. However, being
+the most efficient I/O method available for a long time, many other
+drivers support streaming as well, allocating buffers in DMA-able main
+memory.
+
+A driver can support many sets of buffers. Each set is identified by a
+unique buffer type value. The sets are independent and each set can hold
+a different type of data. To access different sets at the same time
+different file descriptors must be used. [#f1]_
+
+To allocate device buffers applications call the
+:ref:`VIDIOC_REQBUFS` ioctl with the desired number
+of buffers and buffer type, for example ``V4L2_BUF_TYPE_VIDEO_CAPTURE``.
+This ioctl can also be used to change the number of buffers or to free
+the allocated memory, provided none of the buffers are still mapped.
+
+Before applications can access the buffers they must map them into their
+address space with the :ref:`mmap() <func-mmap>` function. The
+location of the buffers in device memory can be determined with the
+:ref:`VIDIOC_QUERYBUF` ioctl. In the single-planar
+API case, the ``m.offset`` and ``length`` returned in a struct
+:c:type:`v4l2_buffer` are passed as sixth and second
+parameter to the :ref:`mmap() <func-mmap>` function. When using the
+multi-planar API, struct :c:type:`v4l2_buffer` contains an
+array of struct :c:type:`v4l2_plane` structures, each
+containing its own ``m.offset`` and ``length``. When using the
+multi-planar API, every plane of every buffer has to be mapped
+separately, so the number of calls to :ref:`mmap() <func-mmap>` should
+be equal to number of buffers times number of planes in each buffer. The
+offset and length values must not be modified. Remember, the buffers are
+allocated in physical memory, as opposed to virtual memory, which can be
+swapped out to disk. Applications should free the buffers as soon as
+possible with the :ref:`munmap() <func-munmap>` function.

+
+Conceptually streaming drivers maintain two buffer queues, an incoming
+and an outgoing queue. They separate the synchronous capture or output
+operation locked to a video clock from the application which is subject
+to random disk or network delays and preemption by other processes,
+thereby reducing the probability of data loss. The queues are organized
+as FIFOs, buffers will be output in the order enqueued in the incoming
+FIFO, and were captured in the order dequeued from the outgoing FIFO.
+
+The driver may require a minimum number of buffers enqueued at all times
+to function, apart of this no limit exists on the number of buffers
+applications can enqueue in advance, or dequeue and process. They can
+also enqueue in a different order than buffers have been dequeued, and
+the driver can *fill* enqueued *empty* buffers in any order.  [#f2]_ The
+index number of a buffer (struct :c:type:`v4l2_buffer`
+``index``) plays no role here, it only identifies the buffer.
+
+Initially all mapped buffers are in dequeued state, inaccessible by the
+driver. For capturing applications it is customary to first enqueue all
+mapped buffers, then to start capturing and enter the read loop. Here
+the application waits until a filled buffer can be dequeued, and
+re-enqueues the buffer when the data is no longer needed. Output
+applications fill and enqueue buffers, when enough buffers are stacked
+up the output is started with :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`.
+In the write loop, when the application runs out of free buffers, it
+must wait until an empty buffer can be dequeued and reused.
+
+To enqueue and dequeue a buffer applications use the
+:ref:`VIVIOC_QBUF <VIDIOC_QBUF>` and :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+ioctl. The status of a buffer being mapped, enqueued, full or empty can
+be determined at any time using the :ref:`VIDIOC_QUERYBUF` ioctl. Two
+methods exist to suspend execution of the application until one or more
+buffers can be dequeued.  By default :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+blocks when no buffer is in the outgoing queue. When the ``O_NONBLOCK``
+flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The :ref:`select() <func-select>`
+or :ref:`poll() <func-poll>` functions are always available.
+
+To start and stop capturing or output applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF
+<VIDIOC_STREAMON>` ioctl.
+
+.. note:::ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+   removes all buffers from both queues as a side effect. Since there is
+   no notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct ::c:type:`v4l2_buffer` ``timestamp`` of captured
+   or outputted buffers.
+
+Drivers implementing memory mapping I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QUERYBUF
+<VIDIOC_QUERYBUF>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the :ref:`mmap()
+<func-mmap>`, :ref:`munmap() <func-munmap>`, :ref:`select()
+<func-select>` and :ref:`poll() <func-poll>` function. [#f3]_
+
+[capture example]
+
+.. [#f1]
+   One could use one file descriptor and set the buffer type field
+   accordingly when calling :ref:`VIDIOC_QBUF` etc.,
+   but it makes the :ref:`select() <func-select>` function ambiguous. We also
+   like the clean approach of one file descriptor per logical stream.
+   Video overlay for example is also a logical stream, although the CPU
+   is not needed for continuous operation.
+
+.. [#f2]
+   Random enqueue order permits applications processing images out of
+   order (such as video codecs) to return buffers earlier, reducing the
+   probability of data loss. Random fill order allows drivers to reuse
+   buffers on a LIFO-basis, taking advantage of caches holding
+   scatter-gather lists and the like.
+
+.. [#f3]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.
+   The rest should be evident.

+
+Device Naming
+=============
+
+V4L2 drivers are implemented as kernel modules, loaded manually by the
+system administrator or automatically when a device is first discovered.
+The driver modules plug into the "videodev" kernel module. It provides
+helper functions and a common application interface specified in this
+document.
+
+Each driver thus loaded registers one or more device nodes with major
+number 81 and a minor number between 0 and 255. Minor numbers are
+allocated dynamically unless the kernel is compiled with the kernel
+option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers
+are allocated in ranges depending on the device node type (video, radio,
+etc.).
+
+Many drivers support "video_nr", "radio_nr" or "vbi_nr" module
+options to select specific video/radio/vbi node numbers. This allows the
+user to request that the device node is named e.g. /dev/video5 instead
+of leaving it to chance. When the driver supports multiple devices of
+the same type more than one device node number can be assigned,
+separated by commas:
+
+.. code-block:: none
+
+   # modprobe mydriver video_nr=0,1 radio_nr=0,1
+
+In ``/etc/modules.conf`` this may be written as:
+
+::
+
+    options mydriver video_nr=0,1 radio_nr=0,1
+
+When no device node number is given as module option the driver supplies
+a default.
+
+Normally udev will create the device nodes in /dev automatically for
+you. If udev is not installed, then you need to enable the
+CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to
+correctly relate a minor number to a device node number. I.e., you need
+to be certain that minor number 5 maps to device node name video5. With
+this kernel option different device types have different minor number
+ranges. These ranges are listed in :ref:`devices`.
+
+The creation of character special files (with mknod) is a privileged
+operation and devices cannot be opened by major and minor number. That
+means applications cannot *reliably* scan for loaded or installed
+drivers. The user must enter a device name, or the application can try
+the conventional device names.
+
+
+.. _related:
+
+Related Devices
+===============
+
+Devices can support several functions. For example video capturing, VBI
+capturing and radio support.
+
+The V4L2 API creates different nodes for each of these functions.
+
+The V4L2 API was designed with the idea that one device node could
+support all functions. However, in practice this never worked: this
+'feature' was never used by applications and many drivers did not
+support it and if they did it was certainly never tested. In addition,
+switching a device node between different functions only works when
+using the streaming I/O API, not with the
+:ref:`read() <func-read>`/\ :ref:`write() <func-write>` API.
+
+Today each device node supports just one function.
+
+Besides video input or output the hardware may also support audio
+sampling or playback. If so, these functions are implemented as ALSA PCM
+devices with optional ALSA audio mixer devices.
+
+One problem with all these devices is that the V4L2 API makes no
+provisions to find these related devices. Some really complex devices
+use the Media Controller (see :ref:`media_controller`) which can be
+used for this purpose. But most drivers do not use it, and while some
+code exists that uses sysfs to discover related devices (see
+libmedia_dev in the
+`v4l-utils <http://git.linuxtv.org/cgit.cgi/v4l-utils.git/>`__ git
+repository), there is no library yet that can provide a single API
+towards both Media Controller-based devices and devices that do not use
+the Media Controller. If you want to work on this please write to the
+linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+
+Multiple Opens
+==============
+
+V4L2 devices can be opened more than once. [#f1]_ When this is supported
+by the driver, users can for example start a "panel" application to
+change controls like brightness or audio volume, while another
+application captures video and audio. In other words, panel applications
+are comparable to an ALSA audio mixer application. Just opening a V4L2
+device should not change the state of the device. [#f2]_
+
+Once an application has allocated the memory buffers needed for
+streaming data (by calling the :ref:`VIDIOC_REQBUFS`
+or :ref:`VIDIOC_CREATE_BUFS` ioctls, or
+implicitly by calling the :ref:`read() <func-read>` or
+:ref:`write() <func-write>` functions) that application (filehandle)
+becomes the owner of the device. It is no longer allowed to make changes
+that would affect the buffer sizes (e.g. by calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl) and other applications are
+no longer allowed to allocate buffers or start or stop streaming. The
+EBUSY error code will be returned instead.
+
+Merely opening a V4L2 device does not grant exclusive access. [#f3]_
+Initiating data exchange however assigns the right to read or write the
+requested type of data, and to change related properties, to this file
+descriptor. Applications can request additional access privileges using
+the priority mechanism described in :ref:`app-pri`.
+
+
+Shared Data Streams
+===================
+
+V4L2 drivers should not support multiple applications reading or writing
+the same data stream on a device by copying buffers, time multiplexing
+or similar means. This is better handled by a proxy application in user
+space.
+
+
+Functions
+=========
+
+To open and close V4L2 devices applications use the
+:ref:`open() <func-open>` and :ref:`close() <func-close>` function,
+respectively. Devices are programmed using the
+:ref:`ioctl() <func-ioctl>` function as explained in the following
+sections.
+
+.. [#f1]
+   There are still some old and obscure drivers that have not been
+   updated to allow for multiple opens. This implies that for such
+   drivers :ref:`open() <func-open>` can return an ``EBUSY`` error code
+   when the device is already in use.
+
+.. [#f2]
+   Unfortunately, opening a radio device often switches the state of the
+   device to radio mode in many drivers. This behavior should be fixed
+   eventually as it violates the V4L2 specification.
+
+.. [#f3]
+   Drivers could recognize the ``O_EXCL`` open flag. Presently this is
+   not required, so applications cannot know if it really works.

+Standard Image Formats
+**********************
+
+In order to exchange images between drivers and applications, it is
+necessary to have standard image data formats which both sides will
+interpret the same way. V4L2 includes several such formats, and this
+section is intended to be an unambiguous specification of the standard
+image data formats in V4L2.
+
+V4L2 drivers are not limited to these formats, however. Driver-specific
+formats are possible. In that case the application may depend on a codec
+to convert images to one of the standard formats when needed. But the
+data can still be stored and retrieved in the proprietary format. For
+example, a device may support a proprietary compressed format.
+Applications can still capture and save the data in the compressed
+format, saving much disk space, and later use a codec to convert the
+images to the X Windows screen format when the video is to be displayed.
+
+Even so, ultimately, some standard formats are needed, so the V4L2
+specification would not be complete without well-defined standard
+formats.
+
+The V4L2 standard formats are mainly uncompressed formats. The pixels
+are always arranged in memory from left to right, and from top to
+bottom. The first byte of data in the image buffer is always for the
+leftmost pixel of the topmost row. Following that is the pixel
+immediately to its right, and so on until the end of the top row of
+pixels. Following the rightmost pixel of the row there may be zero or
+more bytes of padding to guarantee that each row of pixel data has a
+certain alignment. Following the pad bytes, if any, is data for the
+leftmost pixel of the second row from the top, and so on. The last row
+has just as many pad bytes after it as the other rows.
+
+In V4L2 each format has an identifier which looks like ``PIX_FMT_XXX``,
+defined in the :ref:`videodev2.h <videodev>` header file. These
+identifiers represent
+:ref:`four character (FourCC) codes <v4l2-fourcc>` which are also
+listed below, however they are not the same as those used in the Windows
+world.
+
+For some formats, data is stored in separate, discontiguous memory
+buffers. Those formats are identified by a separate set of FourCC codes
+and are referred to as "multi-planar formats". For example, a
+:ref:`YUV422 <V4L2-PIX-FMT-YUV422M>` frame is normally stored in one
+memory buffer, but it can also be placed in two or three separate
+buffers, with Y component in one buffer and CbCr components in another
+in the 2-planar version or with each component in its own buffer in the
+3-planar case. Those sub-buffers are referred to as "*planes*".

+Infrared 10-bit linked with Depth 16-bit images
+
+
+Description
+===========
+
+Proprietary multi-planar format used by Intel SR300 Depth cameras, comprise of
+Infrared image followed by Depth data. The pixel definition is 32-bpp,
+with the Depth and Infrared Data split into separate continuous planes of
+identical dimensions.
+
+
+
+The first plane - Infrared data - is stored according to
+:ref:`V4L2_PIX_FMT_Y10 <V4L2-PIX-FMT-Y10>` greyscale format.
+Each pixel is 16-bit cell, with actual data stored in the 10 LSBs
+with values in range 0 to 1023.
+The six remaining MSBs are padded with zeros.
+
+
+The second plane provides 16-bit per-pixel Depth data arranged in
+:ref:`V4L2-PIX-FMT-Z16 <V4L2-PIX-FMT-Z16>` format.
+
+
+**Frame Structure.**
+Each cell is a 16-bit word with more significant data stored at higher
+memory address (byte order is little-endian).

+Format with ½ horizontal and vertical chroma resolution, also known as

+
+
+Description
+===========
+
+M420 is a YUV format with ½ horizontal and vertical chroma subsampling
+(YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
+Two lines of luma data are followed by one line of chroma data.
+
+The luma plane has one byte per pixel. The chroma plane contains
+interleaved CbCr pixels subsampled by ½ in the horizontal and vertical
+directions. Each CbCr pair belongs to four pixels. For example,
+Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`10`, Y'\ :sub:`11`.
+
+All line lengths are identical: if the Y lines include pad bytes so do
+the CbCr lines.
+
+**Byte Order.**

+Intel D4xx UVC Cameras Metadata
+
+
+Description
+===========
+
+Intel D4xx (D435 and other) cameras include per-frame metadata in their UVC
+payload headers, following the Microsoft(R) UVC extension proposal [1_]. That
+means, that the private D4XX metadata, following the standard UVC header, is
+organised in blocks. D4XX cameras implement several standard block types,
+proposed by Microsoft, and several proprietary ones. Supported standard metadata
+types are MetadataId_CaptureStats (ID 3), MetadataId_CameraExtrinsics (ID 4),
+and MetadataId_CameraIntrinsics (ID 5). For their description see [1_]. This
+document describes proprietary metadata types, used by D4xx cameras.
+
+V4L2_META_FMT_D4XX buffers follow the metadata buffer layout of
+V4L2_META_FMT_UVC with the only difference, that it also includes proprietary
+payload header data. D4xx cameras use bulk transfers and only send one payload
+per frame, therefore their headers cannot be larger than 255 bytes.
+
+Below are proprietary Microsoft style metadata types, used by D4xx cameras,
+where all fields are in little endian order:

+UVC Payload Header Data
+
+
+Description
+===========
+
+This format describes standard UVC metadata, extracted from UVC packet headers
+and provided by the UVC driver through metadata video nodes. That data includes
+exact copies of the standard part of UVC Payload Header contents and auxiliary
+timing information, required for precise interpretation of timestamps, contained
+in those headers. See section "2.4.3.3 Video and Still Image Payload Headers" of
+the "UVC 1.5 Class specification" for details.
+
+Each UVC payload header can be between 2 and 12 bytes large. Buffers can
+contain multiple headers, if multiple such headers have been transmitted by the
+camera for the respective frame. However, the driver may drop headers when the
+buffer is full, when they contain no useful information (e.g. those without the
+SCR field or with that field identical to the previous header), or generally to
+perform rate limiting when the device sends a large number of headers.
+
+Each individual block contains the following fields:
+
+.. flat-table:: UVC Metadata Block
+    :widths: 1 4
+    :header-rows:  1
+    :stub-columns: 0

+
+
+Description
+===========
+
+This format describes histogram data generated by the Renesas R-Car VSP1 1-D
+Histogram (HGO) engine.
+
+The VSP1 HGO is a histogram computation engine that can operate on RGB, YCrCb
+or HSV data. It operates on a possibly cropped and subsampled input image and
+computes the minimum, maximum and sum of all pixels as well as per-channel
+histograms.
+
+The HGO can compute histograms independently per channel, on the maximum of the
+three channels (RGB data only) or on the Y channel only (YCbCr only). It can
+additionally output the histogram with 64 or 256 bins, resulting in four
+possible modes of operation.
+
+- In *64 bins normal mode*, the HGO operates on the three channels independently
+  to compute three 64-bins histograms. RGB, YCbCr and HSV image formats are
+  supported.
+- In *64 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
+  channels to compute a single 64-bins histogram. Only the RGB image format is
+  supported.
+- In *256 bins normal mode*, the HGO operates on the Y channel to compute a
+  single 256-bins histogram. Only the YCbCr image format is supported.
+- In *256 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
+  channels to compute a single 256-bins histogram. Only the RGB image format is
+  supported.
+
+**Byte Order.**
+All data is stored in memory in little endian format. Each cell in the tables
+contains one byte.

+
+
+Description
+===========
+
+This format describes histogram data generated by the Renesas R-Car VSP1
+2-D Histogram (HGT) engine.
+
+The VSP1 HGT is a histogram computation engine that operates on HSV
+data. It operates on a possibly cropped and subsampled input image and
+computes the sum, maximum and minimum of the S component as well as a
+weighted frequency histogram based on the H and S components.
+
+The histogram is a matrix of 6 Hue and 32 Saturation buckets, 192 in
+total. Each HSV value is added to one or more buckets with a weight
+between 1 and 16 depending on the Hue areas configuration. Finding the
+corresponding buckets is done by inspecting the H and S value independently.
+
+The Saturation position **n** (0 - 31) of the bucket in the matrix is
+found by the expression:
+
+    n = S / 8
+
+The Hue position **m** (0 - 5) of the bucket in the matrix depends on
+how the HGT Hue areas are configured. There are 6 user configurable Hue
+Areas which can be configured to cover overlapping Hue values:

+
+When two consecutive areas don't overlap (n+1L is equal to nU) the boundary
+value is considered as part of the lower area.
+
+Pixels with a hue value included in the centre of an area (between nL and nU
+included) are attributed to that single area and given a weight of 16. Pixels
+with a hue value included in the overlapping region between two areas (between
+n+1L and nU excluded) are attributed to both areas and given a weight for each
+of these areas proportional to their position along the diagonal lines
+(rounded down).
+
+The Hue area setup must match one of the following constrains:
+
+::
+
+    0L <= 0U <= 1L <= 1U <= 2L <= 2U <= 3L <= 3U <= 4L <= 4U <= 5L <= 5U

+V4L2_PIX_FMT_NV21
+Formats with ½ horizontal and vertical chroma resolution, also known as
+YUV 4:2:0. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:2:0 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
+combined CbCr plane immediately follows the Y plane in memory. The CbCr
+plane is the same width, in bytes, as the Y plane (and of the image),

+Variation of ``V4L2_PIX_FMT_NV12`` and ``V4L2_PIX_FMT_NV21`` with planes
+non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar, two-plane version of the YUV 4:2:0 format. The
+three components are separated into two sub-images or planes.
+``V4L2_PIX_FMT_NV12M`` differs from ``V4L2_PIX_FMT_NV12`` in that the
+two planes are non-contiguous in memory, i.e. the chroma plane do not
+necessarily immediately follows the luma plane. The luminance data
+occupies the first plane. The Y plane has one byte per pixel. In the
+second plane there is a chrominance data with alternating chroma
+samples. The CbCr plane is the same width, in bytes, as the Y plane (and
+of the image), but is half as tall in pixels. Each CbCr pair belongs to
+four pixels. For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to
+Y'\ :sub:`00`, Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
+``V4L2_PIX_FMT_NV12MT_16X16`` is the tiled version of
+``V4L2_PIX_FMT_NV12M`` with 16x16 macroblock tiles. Here pixels are
+arranged in 16x16 2D tiles and tiles are arranged in linear order in
+memory. ``V4L2_PIX_FMT_NV21M`` is the same as ``V4L2_PIX_FMT_NV12M``
+except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr
+byte.
+
+``V4L2_PIX_FMT_NV12M`` is intended to be used only in drivers and
+applications that support the multi-planar API, described in
+:ref:`planar-apis`.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**

+
+Formats with ½ horizontal and vertical chroma resolution. This format
+has two planes - one for luminance and one for chrominance. Chroma
+samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
+memory layout. Pixels are grouped in macroblocks of 64x32 size. The
+order of macroblocks in memory is also not standard.

+
+Description
+===========
+
+This is the two-plane versions of the YUV 4:2:0 format where data is
+grouped into 64x32 macroblocks. The three components are separated into
+two sub-images or planes. The Y plane has one byte per pixel and pixels
+are grouped into 64x32 macroblocks. The CbCr plane has the same width,
+in bytes, as the Y plane (and the image), but is half as tall in pixels.
+The chroma plane is also grouped into 64x32 macroblocks.
+
+Width of the buffer has to be aligned to the multiple of 128, and height
+alignment is 32. Every four adjacent buffers - two horizontally and two
+vertically are grouped together and are located in memory in Z or
+flipped Z order.
+
+Layout of macroblocks in memory is presented in the following figure.

+    V4L2_PIX_FMT_NV12MT macroblock Z shape memory layout
+
+The requirement that width is multiple of 128 is implemented because,
+the Z shape cannot be cut in half horizontally. In case the vertical
+resolution of macroblocks is odd then the last row of macroblocks is
+arranged in a linear order.
+
+In case of chroma the layout is identical. Cb and Cr samples are
+interleaved. Height of the buffer is aligned to 32.

+V4L2_PIX_FMT_NV42
+Formats with full horizontal and vertical chroma resolutions, also known
+as YUV 4:4:4. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:4:4 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first, with each Y sample stored in one byte per pixel. For
+``V4L2_PIX_FMT_NV24``, a combined CbCr plane immediately follows the Y
+plane in memory. The CbCr plane has the same width and height, in
+pixels, as the Y plane (and the image). Each line contains one CbCr pair
+per pixel, with each Cb and Cr sample stored in one byte.
+``V4L2_PIX_FMT_NV42`` is the same except that the Cb and Cr samples are
+swapped, the CrCb plane starts with a Cr sample.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has
+twice as many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+Description
+===========
+
+The *hue* (h) is measured in degrees, the equivalence between degrees and LSBs
+depends on the hsv-encoding used, see :ref:`colorspaces`.
+The *saturation* (s) and the *value* (v) are measured in percentage of the
+cylinder: 0 being the smallest value and 255 the maximum.
+
+
+The values are packed in 24 or 32 bit formats.

+
+      - ``V4L2_PIX_FMT_S5C_UYVY_JPG``
+      - 'S5CI'
+      - Two-planar format used by Samsung S5C73MX cameras. The first plane
+	contains interleaved JPEG and UYVY image data, followed by meta
+	data in form of an array of offsets to the UYVY data blocks. The
+	actual pointer array follows immediately the interleaved JPEG/UYVY
+	data, the number of entries in this array equals the height of the
+	UYVY image. Each entry is a 4-byte unsigned integer in big endian
+	order and it's an offset to a single pixel line of the UYVY image.
+	The first plane can start either with JPEG or UYVY data chunk. The
+	size of a single UYVY block equals the UYVY image's width
+	multiplied by 2. The size of a JPEG chunk depends on the image and
+	can vary with each line.
+
+	The second plane, at an offset of 4084 bytes, contains a 4-byte
+	offset to the pointer array in the first plane. This offset is
+	followed by a 4-byte value indicating size of the pointer array.
+	All numbers in the second plane are also in big endian order.
+	Remaining data in the second plane is undefined. The information
+	in the second plane allows to easily find location of the pointer
+	array, which can be different for each frame. The size of the
+	pointer array is constant for given UYVY image height.
+
+	In order to extract UYVY and JPEG frames an application can
+	initially set a data pointer to the start of first plane and then
+	add an offset from the first entry of the pointers table. Such a
+	pointer indicates start of an UYVY image pixel line. Whole UYVY
+	line can be copied to a separate buffer. These steps should be
+	repeated for each line, i.e. the number of entries in the pointer
+	array. Anything what's in between the UYVY lines is JPEG data and
+	should be concatenated to form the JPEG stream.

+	(codenamed sunxi) platforms, with 32x32 tiles for the luminance plane
+	and 32x64 tiles for the chrominance plane. The data in each tile is
+	stored in linear order, within the tile bounds. Each tile follows the
+	previous one linearly in memory (from left to right, top to bottom).
+
+	The associated buffer dimensions are aligned to match an integer number
+	of tiles, resulting in 32-aligned resolutions for the luminance plane
+	and 16-aligned resolutions for the chrominance plane (with 2x2
+	subsampling).

+Description
+===========
+
+These formats are designed to match the pixel formats of typical PC
+graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
+These are all packed-pixel formats, meaning all the data for a pixel lie
+next to each other in memory.

+.. note:: Bit 7 is the most significant bit.
+
+The usage and value of the alpha bits (a) in the ARGB and ABGR formats
+(collectively referred to as alpha formats) depend on the device type
+and hardware operation. :ref:`Capture <capture>` devices (including
+capture queues of mem-to-mem devices) fill the alpha component in
+memory. When the device outputs an alpha channel the alpha component
+will have a meaningful value. Otherwise, when the device doesn't output
+an alpha channel but can set the alpha bit to a user-configurable value,
+the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
+is used to specify that alpha value, and the alpha component of all
+pixels will be set to the value specified by that control. Otherwise a
+corresponding format without an alpha component (XRGB or XBGR) must be
+used instead of an alpha format.
+
+:ref:`Output <output>` devices (including output queues of mem-to-mem
+devices and :ref:`video output overlay <osd>` devices) read the alpha
+component from memory. When the device processes the alpha channel the
+alpha component must be filled with meaningful values by applications.
+Otherwise a corresponding format without an alpha component (XRGB or
+XBGR) must be used instead of an alpha format.
+
+The XRGB and XBGR formats contain undefined bits (-). Applications,
+devices and drivers must ignore those bits, for both
+:ref:`capture` and :ref:`output` devices.

+10-bit Bayer formats
+
+Description
+===========
+
+These four pixel formats are used by Intel IPU3 driver, they are raw
+sRGB / Bayer formats with 10 bits per sample with every 25 pixels packed
+to 32 bytes leaving 6 most significant bits padding in the last byte.
+The format is little endian.
+
+In other respects this format is similar to :ref:`V4L2-PIX-FMT-SRGGB10`.
+Below is an example of a small image in V4L2_PIX_FMT_IPU3_SBGGR10 format.
+
+**Byte Order.**
+Each cell is one byte.

+10-bit Bayer formats expanded to 16 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 10 bits per
+sample. Each sample is stored in a 16-bit word, with 6 unused
+high bits filled with zeros. Each n-pixel row contains n/2 green samples and
+n/2 blue or red samples, with alternating red and blue rows. Bytes are
+stored in memory in little endian order. They are conventionally described
+as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of
+these formats:
+
+**Byte Order.**
+Each cell is one byte, the 6 most significant bits in the high bytes
+are 0.

+10-bit Bayer formats compressed to 8 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 10 bits per
+color compressed to 8 bits each, using the A-LAW algorithm. Each color
+component consumes 8 bits of memory. In other respects this format is
+similar to :ref:`V4L2-PIX-FMT-SRGGB8`.

+10-bit Bayer formats compressed to 8 bits
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 10 bits per
+colour compressed to 8 bits each, using DPCM compression. DPCM,
+differential pulse-code modulation, is lossy. Each colour component
+consumes 8 bits of memory. In other respects this format is similar to
+:ref:`V4L2-PIX-FMT-SRGGB10`.

+16-bit Bayer formats
+
+
+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 16 bits per
+sample. Each sample is stored in a 16-bit word. Each n-pixel row contains
+n/2 green samples and n/2 blue or red samples, with alternating red and blue
+rows. Bytes are stored in memory in little endian order. They are
+conventionally described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is
+an example of a small V4L2_PIX_FMT_SBGGR16 image:

+Variation of ``V4L2_PIX_FMT_YUYV`` with different order of samples in
+memory
+
+
+Description
+===========
+
+In this format each four bytes is two pixels. Each four bytes is two
+Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr

+	refers to the number of lines in the field, otherwise it refers to

+    * - :cspan:`2` Applications set these fields to request an image
+	size, drivers return the closest possible values. In case of
+	planar formats the ``width`` and ``height`` applies to the largest
+	plane. To avoid ambiguities drivers must return values rounded up
+	to a multiple of the scale factor of any smaller planes. For
+	example when the image format is YUV 4:2:0, ``width`` and
+	``height`` must be multiples of two.
+
+	For compressed formats that contain the resolution information encoded
+	inside the stream, when fed to a stateful mem2mem decoder, the fields
+	may be zero to rely on the decoder to detect the right values. For more
+	details see :ref:`decoder` and format descriptions.
+    * - __u32
+      - ``pixelformat``
+      - The pixel format or type of compression, set by the application.
+	This is a little endian
+	:ref:`four character code <v4l2-fourcc>`. V4L2 defines standard
+	RGB formats in :ref:`pixfmt-rgb`, YUV formats in
+	:ref:`yuv-formats`, and reserved codes in
+	:ref:`reserved-formats`
+    * - __u32
+      - ``field``
+      - Field order, from enum :c:type:`v4l2_field`.
+        Video images are typically interlaced. Applications can request to
+	capture or output only the top or bottom field, or both fields
+	interlaced or sequentially stored in one buffer or alternating in
+	separate buffers. Drivers return the actual field order selected.
+	For more details on fields see :ref:`field-order`.
+    * - __u32
+      - ``bytesperline``
+      - Distance in bytes between the leftmost pixels in two adjacent
+	lines.
+    * - :cspan:`2`
+
+	Both applications and drivers can set this field to request
+	padding bytes at the end of each line. Drivers however may ignore
+	the value requested by the application, returning ``width`` times
+	bytes per pixel or a larger value required by the hardware. That
+	implies applications can just set this field to zero to get a
+	reasonable default.
+
+	Video hardware may access padding bytes, therefore they must
+	reside in accessible memory. Consider cases where padding bytes
+	after the last line of an image cross a system page boundary.
+	Input devices may write padding bytes, the value is undefined.
+	Output devices ignore the contents of padding bytes.
+
+	When the image format is planar the ``bytesperline`` value applies
+	to the first plane and is divided by the same factor as the
+	``width`` field for the other planes. For example the Cb and Cr
+	planes of a YUV 4:2:0 image have half as many padding bytes
+	following each line as the Y plane. To avoid ambiguities drivers
+	must return a ``bytesperline`` value rounded up to a multiple of
+	the scale factor.
+
+	For compressed formats the ``bytesperline`` value makes no sense.
+	Applications and drivers must set this to 0 in that case.
+    * - __u32
+      - ``sizeimage``
+      - Size in bytes of the buffer to hold a complete image, set by the
+	driver. Usually this is ``bytesperline`` times ``height``. When
+	the image consists of variable length compressed data this is the
+	number of bytes required by the codec to support the worst-case
+	compression scenario.
+
+	The driver will set the value for uncompressed images.
+
+	Clients are allowed to set the sizeimage field for variable length
+	compressed data flagged with ``V4L2_FMT_FLAG_COMPRESSED`` at
+	:ref:`VIDIOC_ENUM_FMT`, but the driver may ignore it and set the
+	value itself, or it may modify the provided value based on
+	alignment requirements or minimum/maximum size requirements.
+	If the client wants to leave this to the driver, then it should
+	set sizeimage to 0.
+    * - __u32
+      - ``colorspace``
+      - Image colorspace, from enum :c:type:`v4l2_colorspace`.
+        This information supplements the ``pixelformat`` and must be set
+	by the driver for capture streams and by the application for
+	output streams, see :ref:`colorspaces`.
+    * - __u32
+      - ``priv``
+      - This field indicates whether the remaining fields of the
+	struct :c:type:`v4l2_pix_format`, also called the
+	extended fields, are valid. When set to
+	``V4L2_PIX_FMT_PRIV_MAGIC``, it indicates that the extended fields
+	have been correctly initialized. When set to any other value it
+	indicates that the extended fields contain undefined values.
+
+	Applications that wish to use the pixel format extended fields
+	must first ensure that the feature is supported by querying the
+	device for the :ref:`V4L2_CAP_EXT_PIX_FORMAT <querycap>`
+	capability. If the capability isn't set the pixel format extended
+	fields are not supported and using the extended fields will lead
+	to undefined results.
+
+	To use the extended fields, applications must set the ``priv``
+	field to ``V4L2_PIX_FMT_PRIV_MAGIC``, initialize all the extended
+	fields and zero the unused bytes of the
+	struct :c:type:`v4l2_format` ``raw_data`` field.
+
+	When the ``priv`` field isn't set to ``V4L2_PIX_FMT_PRIV_MAGIC``
+	drivers must act as if all the extended fields were set to zero.
+	On return drivers must set the ``priv`` field to
+	``V4L2_PIX_FMT_PRIV_MAGIC`` and all the extended fields to
+	applicable values.

+Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1
+
+
+Description
+===========
+
+In this format each 12 bytes is eight pixels. In the twelve bytes are
+two CbCr pairs and eight Y's. The first CbCr pair goes with the first
+four Y's, and the second CbCr pair goes with the other four Y's. The Cb
+and Cr components have one fourth the horizontal resolution of the Y
+component.
+
+Do not confuse this format with
+:ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
+from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1

+V4L2_PIX_FMT_YUV410
+Planar formats with ¼ horizontal and vertical chroma resolution, also
+known as YUV 4:1:0
+
+
+Description
+===========
+
+These are planar formats, as opposed to a packed format. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
+the Cr plane immediately follows the Y plane in memory. The Cr plane is
+¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
+belongs to 16 pixels, a four-by-four square of the image. Following the
+Cr plane is the Cb plane, just like the Cr plane.
+``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
+then the Cr plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four Cx rows
+(including padding) are exactly as long as one Y row (including
+padding).
+
+**Byte Order.**
+Each cell is one byte.

+Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1.
+Planar layout as opposed to ``V4L2_PIX_FMT_Y41P``
+
+
+Description
+===========
+
+This format is not commonly used. This is a planar format similar to the
+4:2:2 planar format except with half as many chroma. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. The Cb plane immediately
+follows the Y plane in memory. The Cb plane is ¼ the width of the Y
+plane (and of the image). Each Cb belongs to 4 pixels all on the same
+row. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`02` and Y'\ :sub:`03`. Following the Cb plane is the Cr plane,
+just like the Cb plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four C x rows
+(including padding) is exactly as long as one Y row (including padding).

+Variation of ``V4L2_PIX_FMT_YUV420`` and ``V4L2_PIX_FMT_YVU420`` with
+planes non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar format, as opposed to a packed format. The three
+components are separated into three sub-images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. For
+``V4L2_PIX_FMT_YUV420M`` the Cb data constitutes the second plane which
+is half the width and half the height of the Y plane (and of the image).
+Each Cb belongs to four pixels, a two-by-two square of the image. For
+example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`10`, and Y'\ :sub:`11`. The Cr data, just like the Cb plane,
+is in the third plane.
+
+``V4L2_PIX_FMT_YVU420M`` is the same except the Cr data is stored in the
+second plane and the Cb data in the third plane.
+
+If the Y plane has pad bytes after each row, then the Cb and Cr planes
+have half as many pad bytes after their rows. In other words, two Cx
+rows (including padding) is exactly as long as one Y row (including
+padding).
+
+``V4L2_PIX_FMT_YUV420M`` and ``V4L2_PIX_FMT_YVU420M`` are intended to be
+used only in drivers and applications that support the multi-planar API,
+described in :ref:`planar-apis`.
+
+**Byte Order.**
+Each cell is one byte.

+*****************************
+Single- and multi-planar APIs
+*****************************
+
+Some devices require data for each input or output video frame to be
+placed in discontiguous memory buffers. In such cases, one video frame
+has to be addressed using more than one memory address, i.e. one pointer
+per "plane". A plane is a sub-buffer of the current frame. For examples
+of such formats see :ref:`pixfmt`.
+
+Initially, V4L2 API did not support multi-planar buffers and a set of
+extensions has been introduced to handle them. Those extensions
+constitute what is being referred to as the "multi-planar API".
+
+Some of the V4L2 API calls and structures are interpreted differently,
+depending on whether single- or multi-planar API is being used. An
+application can choose whether to use one or the other by passing a
+corresponding buffer type to its ioctl calls. Multi-planar versions of
+buffer types are suffixed with an ``_MPLANE`` string. For a list of
+available multi-planar buffer types see enum
+:c:type:`v4l2_buf_type`.
+
+
+Multi-planar formats
+====================
+
+Multi-planar API introduces new multi-planar formats. Those formats use
+a separate set of FourCC codes. It is important to distinguish between
+the multi-planar API and a multi-planar format. Multi-planar API calls
+can handle all single-planar formats as well (as long as they are passed
+in multi-planar API structures), while the single-planar API cannot
+handle multi-planar formats.
+
+
+Calls that distinguish between single and multi-planar APIs
+===========================================================
+
+:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>`
+    Two additional multi-planar capabilities are added. They can be set
+    together with non-multi-planar ones for devices that handle both
+    single- and multi-planar formats.
+
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`
+    New structures for describing multi-planar formats are added: struct
+    :c:type:`v4l2_pix_format_mplane` and
+    struct :c:type:`v4l2_plane_pix_format`.
+    Drivers may define new multi-planar formats, which have distinct
+    FourCC codes from the existing single-planar ones.
+
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>`
+    A new struct :c:type:`v4l2_plane` structure for
+    describing planes is added. Arrays of this structure are passed in
+    the new ``m.planes`` field of struct
+    :c:type:`v4l2_buffer`.
+
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
+    Will allocate multi-planar buffers as requested.

+*********************
+Querying Capabilities
+*********************
+
+Because V4L2 covers a wide variety of devices not all aspects of the API
+are equally applicable to all types of devices. Furthermore devices of
+the same type have different capabilities and this specification permits
+the omission of a few complicated and less important parts of the API.
+
+The :ref:`VIDIOC_QUERYCAP` ioctl is available to
+check if the kernel device is compatible with this specification, and to
+query the :ref:`functions <devices>` and :ref:`I/O methods <io>`
+supported by the device.
+
+Starting with kernel version 3.1, :ref:`VIDIOC_QUERYCAP`
+will return the V4L2 API version used by the driver, with generally
+matches the Kernel version. There's no need of using
+:ref:`VIDIOC_QUERYCAP` to check if a specific ioctl
+is supported, the V4L2 core now returns ``ENOTTY`` if a driver doesn't
+provide support for an ioctl.
+
+Other features can be queried by calling the respective ioctl, for
+example :ref:`VIDIOC_ENUMINPUT` to learn about the
+number, types and names of video connectors on the device. Although
+abstraction is a major objective of this API, the
+:ref:`VIDIOC_QUERYCAP` ioctl also allows driver
+specific applications to reliably identify the driver.
+
+All V4L2 drivers must support :ref:`VIDIOC_QUERYCAP`.
+Applications should always call this ioctl after opening the device.

+Read/Write
+**********
+
+Input and output devices support the :ref:`read() <func-read>` and
+:ref:`write() <func-write>` function, respectively, when the
+``V4L2_CAP_READWRITE`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set.
+
+Drivers may need the CPU to copy the data, but they may also support DMA
+to or from user memory, so this I/O method is not necessarily less
+efficient than other methods merely exchanging buffer pointers. It is
+considered inferior though because no meta-information like frame
+counters or timestamps are passed. This information is necessary to
+recognize frame dropping and to synchronize with other data streams.
+However this is also the simplest I/O method, requiring little or no
+setup to exchange data. It permits command line stunts like this (the
+vidctrl tool is fictitious):
+
+
+.. code-block:: none
+
+    $ vidctrl /dev/video --input=0 --format=YUYV --size=352x288
+    $ dd if=/dev/video of=myimage.422 bs=202752 count=1
+
+To read from the device applications use the :ref:`read() <func-read>`
+function, to write the :ref:`write() <func-write>` function. Drivers
+must implement one I/O method if they exchange data with applications,
+but it need not be this. [#f1]_ When reading or writing is supported, the
+driver must also support the :ref:`select() <func-select>` and
+:ref:`poll() <func-poll>` function. [#f2]_
+
+.. [#f1]
+   It would be desirable if applications could depend on drivers
+   supporting all I/O interfaces, but as much as the complex memory
+   mapping I/O can be inadequate for some devices we have no reason to
+   require this interface, which is most useful for simple applications
+   capturing still images.
+
+.. [#f2]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.

+Configuration
+*************
+
+Applications can use the :ref:`selection API <VIDIOC_G_SELECTION>` to
+select an area in a video signal or a buffer, and to query for default
+settings and hardware limits.
+
+Video hardware can have various cropping, composing and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in the horizontal and
+vertical directions. Also it may not support scaling at all. At the same
+time the cropping/composing rectangles may have to be aligned, and both
+the source and the sink may have arbitrary upper and lower size limits.
+Therefore, as usual, drivers are expected to adjust the requested
+parameters and return the actual values selected. An application can
+control the rounding behaviour using
+:ref:`constraint flags <v4l2-selection-flags>`.
+
+
+Configuration of video capture
+==============================
+
+See figure :ref:`sel-targets-capture` for examples of the selection
+targets available for a video capture device. It is recommended to
+configure the cropping targets before to the composing targets.
+
+The range of coordinates of the top left corner, width and height of
+areas that can be sampled is given by the ``V4L2_SEL_TGT_CROP_BOUNDS``
+target. It is recommended for the driver developers to put the top/left
+corner at position ``(0,0)``. The rectangle's coordinates are expressed
+in pixels.
+
+The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by the ``V4L2_SEL_TGT_CROP`` target.
+It uses the same coordinate system as ``V4L2_SEL_TGT_CROP_BOUNDS``. The
+active cropping area must lie completely inside the capture boundaries.
+The driver may further adjust the requested size and/or position
+according to hardware limitations.
+
+Each capture device has a default source rectangle, given by the
+``V4L2_SEL_TGT_CROP_DEFAULT`` target. This rectangle shall cover what the
+driver writer considers the complete picture. Drivers shall set the
+active crop rectangle to the default when the driver is first loaded,
+but not later.
+
+The composing targets refer to a memory buffer. The limits of composing
+coordinates are obtained using ``V4L2_SEL_TGT_COMPOSE_BOUNDS``. All
+coordinates are expressed in pixels. The rectangle's top/left corner
+must be located at position ``(0,0)``. The width and height are equal to
+the image size set by :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
+
+The part of a buffer into which the image is inserted by the hardware is
+controlled by the ``V4L2_SEL_TGT_COMPOSE`` target. The rectangle's
+coordinates are also expressed in the same coordinate system as the
+bounds rectangle. The composing rectangle must lie completely inside
+bounds rectangle. The driver must adjust the composing rectangle to fit
+to the bounding limits. Moreover, the driver can perform other
+adjustments according to hardware limitations. The application can
+control rounding behaviour using
+:ref:`constraint flags <v4l2-selection-flags>`.
+
+For capture devices the default composing rectangle is queried using
+``V4L2_SEL_TGT_COMPOSE_DEFAULT``. It is usually equal to the bounding
+rectangle.
+
+The part of a buffer that is modified by the hardware is given by
+``V4L2_SEL_TGT_COMPOSE_PADDED``. It contains all pixels defined using
+``V4L2_SEL_TGT_COMPOSE`` plus all padding data modified by hardware
+during insertion process. All pixels outside this rectangle *must not*
+be changed by the hardware. The content of pixels that lie inside the
+padded area but outside active area is undefined. The application can
+use the padded and active rectangles to detect where the rubbish pixels
+are located and remove them if needed.
+
+
+Configuration of video output
+=============================
+
+For output devices targets and ioctls are used similarly to the video
+capture case. The *composing* rectangle refers to the insertion of an
+image into a video signal. The cropping rectangles refer to a memory
+buffer. It is recommended to configure the composing targets before to
+the cropping targets.
+
+The cropping targets refer to the memory buffer that contains an image
+to be inserted into a video signal or graphical screen. The limits of
+cropping coordinates are obtained using ``V4L2_SEL_TGT_CROP_BOUNDS``.
+All coordinates are expressed in pixels. The top/left corner is always
+point ``(0,0)``. The width and height is equal to the image size
+specified using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+The top left corner, width and height of the source rectangle, that is
+the area from which image date are processed by the hardware, is given
+by the ``V4L2_SEL_TGT_CROP``. Its coordinates are expressed in in the
+same coordinate system as the bounds rectangle. The active cropping area
+must lie completely inside the crop boundaries and the driver may
+further adjust the requested size and/or position according to hardware
+limitations.
+
+For output devices the default cropping rectangle is queried using
+``V4L2_SEL_TGT_CROP_DEFAULT``. It is usually equal to the bounding
+rectangle.
+
+The part of a video signal or graphics display where the image is
+inserted by the hardware is controlled by ``V4L2_SEL_TGT_COMPOSE``
+target. The rectangle's coordinates are expressed in pixels. The
+composing rectangle must lie completely inside the bounds rectangle. The
+driver must adjust the area to fit to the bounding limits. Moreover, the
+driver can perform other adjustments according to hardware limitations.
+
+The device has a default composing rectangle, given by the
+``V4L2_SEL_TGT_COMPOSE_DEFAULT`` target. This rectangle shall cover what
+the driver writer considers the complete picture. It is recommended for
+the driver developers to put the top/left corner at position ``(0,0)``.
+Drivers shall set the active composing rectangle to the default one when
+the driver is first loaded.
+
+The devices may introduce additional content to video signal other than
+an image from memory buffers. It includes borders around an image.
+However, such a padded area is driver-dependent feature not covered by
+this document. Driver developers are encouraged to keep padded rectangle
+equal to active one. The padded target is accessed by the
+``V4L2_SEL_TGT_COMPOSE_PADDED`` identifier. It must contain all pixels
+from the ``V4L2_SEL_TGT_COMPOSE`` target.
+
+
+Scaling control
+===============
+
+An application can detect if scaling is performed by comparing the width
+and the height of rectangles obtained using ``V4L2_SEL_TGT_CROP`` and
+``V4L2_SEL_TGT_COMPOSE`` targets. If these are not equal then the
+scaling is applied. The application can compute the scaling ratios using
+these values.

+Introduction
+************
+
+Some video capture devices can sample a subsection of a picture and
+shrink or enlarge it to an image of arbitrary size. Next, the devices
+can insert the image into larger one. Some video output devices can crop
+part of an input image, scale it up or down and insert it at an
+arbitrary scan line and horizontal offset into a video signal. We call
+these abilities cropping, scaling and composing.
+
+On a video *capture* device the source is a video signal, and the
+cropping target determine the area actually sampled. The sink is an
+image stored in a memory buffer. The composing area specifies which part
+of the buffer is actually written to by the hardware.
+
+On a video *output* device the source is an image in a memory buffer,
+and the cropping target is a part of an image to be shown on a display.
+The sink is the display or the graphics screen. The application may
+select the part of display where the image should be displayed. The size
+and position of such a window is controlled by the compose target.
+
+Rectangles for all cropping and composing targets are defined even if
+the device does supports neither cropping nor composing. Their size and
+position will be fixed in such a case. If the device does not support
+scaling then the cropping and composing rectangles have the same size.

+********************************
+Comparison with old cropping API
+********************************
+
+The selection API was introduced to cope with deficiencies of the
+older :ref:`CROP API <crop>`, that was designed to control simple
+capture devices. Later the cropping API was adopted by video output
+drivers. The ioctls are used to select a part of the display were the
+video signal is inserted. It should be considered as an API abuse
+because the described operation is actually the composing. The
+selection API makes a clear distinction between composing and cropping
+operations by setting the appropriate targets.
+
+The CROP API lacks any support for composing to and cropping from an
+image inside a memory buffer. The application could configure a
+capture device to fill only a part of an image by abusing V4L2
+API. Cropping a smaller image from a larger one is achieved by setting
+the field ``bytesperline`` at struct :c:type:`v4l2_pix_format`.
+Introducing an image offsets could be done by modifying field
+``m_userptr`` at struct :c:type:`v4l2_buffer` before calling
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`. Those operations should be avoided
+because they are not portable (endianness), and do not work for
+macroblock and Bayer formats and mmap buffers.
+
+The selection API deals with configuration of buffer
+cropping/composing in a clear, intuitive and portable way. Next, with
+the selection API the concepts of the padded target and constraints
+flags are introduced. Finally, struct :c:type:`v4l2_crop` and struct
+:c:type:`v4l2_cropcap` have no reserved fields. Therefore there is no
+way to extend their functionality. The new struct
+:c:type:`v4l2_selection` provides a lot of place for future
+extensions.
+
+Driver developers are encouraged to implement only selection API. The
+former cropping API would be simulated using the new one.

+============================
+
+While the :ref:`V4L2 selection API <selection-api>` and
+:ref:`V4L2 subdev selection APIs <v4l2-subdev-selections>` are very
+similar, there's one fundamental difference between the two. On
+sub-device API, the selection rectangle refers to the media bus format,
+and is bound to a sub-device's pad. On the V4L2 interface the selection
+rectangles refer to the in-memory pixel format.
+
+This section defines the common definitions of the selection interfaces

+Video Standards
+***************
+
+Video devices typically support one or more different video standards or
+variations of standards. Each video input and output may support another
+set of standards. This set is reported by the ``std`` field of struct
+:c:type:`v4l2_input` and struct
+:c:type:`v4l2_output` returned by the
+:ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` ioctls, respectively.
+
+V4L2 defines one bit for each analog video standard currently in use
+worldwide, and sets aside bits for driver defined standards, e. g.
+hybrid standards to watch NTSC video tapes on PAL TVs and vice versa.
+Applications can use the predefined bits to select a particular
+standard, although presenting the user a menu of supported standards is
+preferred. To enumerate and query the attributes of the supported
+standards applications use the :ref:`VIDIOC_ENUMSTD`
+ioctl.
+
+Many of the defined standards are actually just variations of a few
+major standards. The hardware may in fact not distinguish between them,
+or do so internal and switch automatically. Therefore enumerated
+standards also contain sets of one or more standard bits.
+
+Assume a hypothetic tuner capable of demodulating B/PAL, G/PAL and I/PAL
+signals. The first enumerated standard is a set of B and G/PAL, switched
+automatically depending on the selected radio frequency in UHF or VHF
+band. Enumeration gives a "PAL-B/G" or "PAL-I" choice. Similar a
+Composite input may collapse standards, enumerating "PAL-B/G/H/I",
+"NTSC-M" and "SECAM-D/K". [#f1]_
+
+To query and select the standard used by the current video input or
+output applications call the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` ioctl, respectively. The
+*received* standard can be sensed with the
+:ref:`VIDIOC_QUERYSTD` ioctl.
+
+.. note::
+
+   The parameter of all these ioctls is a pointer to a
+   :ref:`v4l2_std_id <v4l2-std-id>` type (a standard set), *not* an
+   index into the standard enumeration. Drivers must implement all video
+   standard ioctls when the device has one or more video inputs or outputs.
+
+Special rules apply to devices such as USB cameras where the notion of
+video standards makes little sense. More generally for any capture or
+output device which is:
+
+-  incapable of capturing fields or frames at the nominal rate of the
+   video standard, or
+
+-  that does not support the video standard formats at all.
+
+Here the driver shall set the ``std`` field of struct
+:c:type:`v4l2_input` and struct
+:c:type:`v4l2_output` to zero and the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>`,
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>`, :ref:`VIDIOC_QUERYSTD` and :ref:`VIDIOC_ENUMSTD` ioctls
+shall return the ``ENOTTY`` error code or the ``EINVAL`` error code.
+
+Applications can make use of the :ref:`input-capabilities` and
+:ref:`output-capabilities` flags to determine whether the video
+standard ioctls can be used with the given input or output.

+Streaming Parameters
+********************
+
+Streaming parameters are intended to optimize the video capture process
+as well as I/O. Presently applications can request a high quality
+capture mode with the :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl.
+
+The current video standard determines a nominal number of frames per
+second. If less than this number of frames is to be captured or output,
+applications can request frame skipping or duplicating on the driver
+side. This is especially useful when using the
+:ref:`read() <func-read>` or :ref:`write() <func-write>`, which are
+not augmented by timestamps or sequence counters, and to avoid
+unnecessary data copying.
+
+Finally these ioctls can be used to determine the number of buffers used
+internally by a driver in read/write mode. For implications see the
+section discussing the :ref:`read() <func-read>` function.
+
+To get and set the streaming parameters applications call the
+:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
+:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take
+a pointer to a struct :c:type:`v4l2_streamparm`, which
+contains a union holding separate parameters for input and output
+devices.
+
+These ioctls are optional, drivers need not implement them. If so, they
+return the ``EINVAL`` error code.

+
+Media Bus Pixel Codes
+---------------------
+
+The media bus pixel codes describe image formats as flowing over
+physical buses (both between separate physical components and inside
+SoC devices). This should not be confused with the V4L2 pixel formats
+that describe, using four character codes, image formats as stored in
+memory.
+
+While there is a relationship between image formats on buses and image
+formats in memory (a raw Bayer image won't be magically converted to
+JPEG just by storing it to memory), there is no one-to-one
+correspondence between them.
+
+The media bus pixel codes document parallel formats. Should the pixel data be
+transported over a serial bus, the media bus pixel code that describes a
+parallel format that transfers a sample on a single clock cycle is used. For
+instance, both MEDIA_BUS_FMT_BGR888_1X24 and MEDIA_BUS_FMT_BGR888_3X8 are used
+on parallel busses for transferring an 8 bits per sample BGR data, whereas on
+serial busses the data in this format is only referred to using
+MEDIA_BUS_FMT_BGR888_1X24. This is because there is effectively only a single
+way to transport that format on the serial busses.
+
+Packed RGB Formats
+^^^^^^^^^^^^^^^^^^
+
+Those formats transfer pixel data as red, green and blue components. The
+format code is made of the following information.
+
+-  The red, green and blue components order code, as encoded in a pixel
+   sample. Possible values are RGB and BGR.
+
+-  The number of bits per component, for each component. The values can
+   be different for all components. Common values are 555 and 565.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1 and 2.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO). A "C" prefix is used for
+   component-wise padding in the most high order bits (CPADHI) or low
+   order bits (CPADLO) of each separate component.
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+For instance, a format where pixels are encoded as 5-bits red, 5-bits
+green and 5-bit blue values padded on the high bit, transferred as 2
+8-bit samples per pixel with the most significant bits (padding, red and
+half of the green value) transferred first will be named
+``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``.
+
+The following tables list existing packed RGB formats.
+
+.. HACK: ideally, we would be using adjustbox here. However, Sphinx
+.. is a very bad behaviored guy: if the table has more than 30 cols,
+.. it switches to long table, and there's no way to override it.

+On LVDS buses, usually each sample is transferred serialized in seven
+time slots per pixel clock, on three (18-bit) or four (24-bit)
+differential data pairs at the same time. The remaining bits are used
+for control signals as defined by SPWG/PSWG/VESA or JEIDA standards. The

+Bayer Formats
+^^^^^^^^^^^^^
+
+Those formats transfer pixel data as red, green and blue components. The
+format code is made of the following information.
+
+-  The red, green and blue components order code, as encoded in a pixel
+   sample. The possible values are shown in :ref:`bayer-patterns`.
+
+-  The number of bits per pixel component. All components are
+   transferred on the same number of bits. Common values are 8, 10 and
+   12.
+
+-  The compression (optional). If the pixel components are ALAW- or
+   DPCM-compressed, a mention of the compression scheme and the number
+   of bits per compressed pixel component.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1 and 2.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO).
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+For instance, a format with uncompressed 10-bit Bayer components
+arranged in a red, green, green, blue pattern transferred as 2 8-bit
+samples per pixel with the least significant bits transferred first will
+be named ``MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE``.

+Packed YUV Formats
+^^^^^^^^^^^^^^^^^^
+
+Those data formats transfer pixel data as (possibly downsampled) Y, U
+and V components. Some formats include dummy bits in some of their
+samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma)
+formats. One cannot rely on the values of these dummy bits as those are
+undefined.
+
+The format code is made of the following information.
+
+-  The Y, U and V components order code, as transferred on the bus.
+   Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
+   dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC
+   formats.
+
+-  The number of bits per pixel component. All components are
+   transferred on the same number of bits. Common values are 8, 10 and
+   12.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   0.5 (encoded as 0_5; in this case two pixels are transferred per bus
+   sample), 1, 1.5 (encoded as 1_5) and 2.
+
+-  The bus width. When the bus width is larger than the number of bits
+   per pixel component, several components are packed in a single bus
+   sample. The components are ordered as specified by the order code,
+   with components on the left of the code transferred in the high order
+   bits. Common values are 8 and 16.
+
+For instance, a format where pixels are encoded as 8-bit YUV values
+downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in
+the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``.
+
+:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and
+describes the organization of each pixel data in each sample. When a
+format pattern is split across multiple samples each of the samples in
+the pattern is described.
+
+The role of each bit transferred over the bus is identified by one of
+the following codes.
+
+-  y\ :sub:`x` for luma component bit number x
+
+-  u\ :sub:`x` for blue chroma component bit number x
+
+-  v\ :sub:`x` for red chroma component bit number x
+
+-  a\ :sub:`x` for alpha component bit number x
+
+- for non-available bits (for positions higher than the bus width)
+
+-  d for dummy bits

+HSV/HSL Formats
+^^^^^^^^^^^^^^^
+
+Those formats transfer pixel data as RGB values in a
+cylindrical-coordinate system using Hue-Saturation-Value or
+Hue-Saturation-Lightness components. The format code is made of the
+following information.
+
+-  The hue, saturation, value or lightness and optional alpha components
+   order code, as encoded in a pixel sample. The only currently
+   supported value is AHSV.
+
+-  The number of bits per component, for each component. The values can
+   be different for all components. The only currently supported value
+   is 8888.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. The only currently
+   supported value is 1.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO).
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+The following table lists existing HSV/HSL formats.

+JPEG Compressed Formats
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Those data formats consist of an ordered sequence of 8-bit bytes
+obtained from JPEG compression process. Additionally to the ``_JPEG``
+postfix the format code is made of the following information.
+
+-  The number of bus samples per entropy encoded byte.
+
+-  The bus width.
+
+For instance, for a JPEG baseline process and an 8-bit bus width the
+format will be named ``MEDIA_BUS_FMT_JPEG_1X8``.
+
+The following table lists existing JPEG compressed formats.

+
+*********************
+Tuners and Modulators
+*********************
+
+
+Tuners
+======
+
+Video input devices can have one or more tuners demodulating a RF
+signal. Each tuner is associated with one or more video inputs,
+depending on the number of RF connectors on the tuner. The ``type``
+field of the respective struct :c:type:`v4l2_input`
+returned by the :ref:`VIDIOC_ENUMINPUT` ioctl is
+set to ``V4L2_INPUT_TYPE_TUNER`` and its ``tuner`` field contains the
+index number of the tuner.
+
+Radio input devices have exactly one tuner with index zero, no video
+inputs.
+
+To query and change tuner properties applications use the
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
+:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` ioctls, respectively. The
+struct :c:type:`v4l2_tuner` returned by :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>`
+also contains signal status information applicable when the tuner of the
+current video or radio input is queried.
+
+.. note::
+
+   :ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` does not switch the
+   current tuner, when there is more than one. The tuner is solely
+   determined by the current video input. Drivers must support both ioctls
+   and set the ``V4L2_CAP_TUNER`` flag in the struct :c:type:`v4l2_capability`
+   returned by the :ref:`VIDIOC_QUERYCAP` ioctl when the
+   device has one or more tuners.
+
+
+Modulators
+==========
+
+Video output devices can have one or more modulators, that modulate a
+video signal for radiation or connection to the antenna input of a TV
+set or video recorder. Each modulator is associated with one or more
+video outputs, depending on the number of RF connectors on the
+modulator. The ``type`` field of the respective struct
+:c:type:`v4l2_output` returned by the
+:ref:`VIDIOC_ENUMOUTPUT` ioctl is set to
+``V4L2_OUTPUT_TYPE_MODULATOR`` and its ``modulator`` field contains the
+index number of the modulator.
+
+Radio output devices have exactly one modulator with index zero, no
+video outputs.
+
+A video or radio device cannot support both a tuner and a modulator. Two
+separate device nodes will have to be used for such hardware, one that
+supports the tuner functionality and one that supports the modulator
+functionality. The reason is a limitation with the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl where you
+cannot specify whether the frequency is for a tuner or a modulator.
+
+To query and change modulator properties applications use the
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` and
+:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Note that
+:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` does not switch the current modulator, when there
+is more than one at all. The modulator is solely determined by the
+current video output. Drivers must support both ioctls and set the
+``V4L2_CAP_MODULATOR`` flag in the struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl when the device has
+one or more modulators.
+
+
+Radio Frequency
+===============
+
+To get and set the tuner or modulator radio frequency applications use
+the :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl which both take
+a pointer to a struct :c:type:`v4l2_frequency`. These
+ioctls are used for TV and radio devices alike. Drivers must support
+both ioctls when the tuner or modulator ioctls are supported, or when
+the device is a radio device.

+*****************************
+Streaming I/O (User Pointers)
+*****************************
+
+Input and output devices support this I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:c:type:`v4l2_capability` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set. If the
+particular user pointer method (not only memory mapping) is supported
+must be determined by calling the :ref:`VIDIOC_REQBUFS` ioctl
+with the memory type set to ``V4L2_MEMORY_USERPTR``.
+
+This I/O method combines advantages of the read/write and memory mapping
+methods. Buffers (planes) are allocated by the application itself, and
+can reside for example in virtual or shared memory. Only pointers to
+data are exchanged, these pointers and meta-information are passed in
+struct :c:type:`v4l2_buffer` (or in struct
+:c:type:`v4l2_plane` in the multi-planar API case). The
+driver must be switched into user pointer I/O mode by calling the
+:ref:`VIDIOC_REQBUFS` with the desired buffer type.
+No buffers (planes) are allocated beforehand, consequently they are not
+indexed and cannot be queried like mapped buffers with the
+:ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>` ioctl.
+
+Example: Initiating streaming I/O with user pointers
+====================================================
+
+.. code-block:: c
+
+    struct v4l2_requestbuffers reqbuf;
+
+    memset (&reqbuf, 0, sizeof (reqbuf));
+    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+    reqbuf.memory = V4L2_MEMORY_USERPTR;
+
+    if (ioctl (fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
+	if (errno == EINVAL)
+	    printf ("Video capturing or user pointer streaming is not supported\\n");
+	else
+	    perror ("VIDIOC_REQBUFS");
+
+	exit (EXIT_FAILURE);
+    }
+
+Buffer (plane) addresses and sizes are passed on the fly with the
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. Although buffers are commonly
+cycled, applications can pass different addresses and sizes at each
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call. If required by the hardware the
+driver swaps memory pages within physical memory to create a continuous
+area of memory. This happens transparently to the application in the
+virtual memory subsystem of the kernel. When buffer pages have been
+swapped out to disk they are brought back and finally locked in physical
+memory for DMA. [#f1]_
+
+Filled or displayed buffers are dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
+memory pages at any time between the completion of the DMA and this
+ioctl. The memory is also unlocked when
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
+:ref:`VIDIOC_REQBUFS`, or when the device is closed.
+Applications must take care not to free buffers without dequeuing.
+Firstly, the buffers remain locked for longer, wasting physical memory.
+Secondly the driver will not be notified when the memory is returned to
+the application's free list and subsequently reused for other purposes,
+possibly completing the requested DMA and overwriting valuable data.
+
+For capturing applications it is customary to enqueue a number of empty
+buffers, to start capturing and enter the read loop. Here the
+application waits until a filled buffer can be dequeued, and re-enqueues
+the buffer when the data is no longer needed. Output applications fill
+and enqueue buffers, when enough buffers are stacked up output is
+started. In the write loop, when the application runs out of free
+buffers it must wait until an empty buffer can be dequeued and reused.
+Two methods exist to suspend execution of the application until one or
+more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
+``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The :ref:`select()
+<func-select>` or :ref:`poll() <func-poll>` function are always
+available.
+
+To start and stop capturing or output applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctl.
+
+.. note::
+
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
+   both queues and unlocks all buffers as a side effect. Since there is no
+   notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct :c:type:`v4l2_buffer` ``timestamp`` of captured or
+   outputted buffers.
+
+Drivers implementing user pointer I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>` function. [#f2]_
+
+.. [#f1]
+   We expect that frequently used buffers are typically not swapped out.
+   Anyway, the process of swapping, locking or generating scatter-gather
+   lists may be time consuming. The delay can be masked by the depth of
+   the incoming buffer queue, and perhaps by maintaining caches assuming
+   a buffer will be soon enqueued again. On the other hand, to optimize
+   memory usage drivers can limit the number of buffers locked in
+   advance and recycle the most recently used buffers first. Of course,
+   the pages of empty buffers in the incoming queue need not be saved to
+   disk. Output buffers must be saved on the incoming and outgoing queue
+   because an application may share them with other processes.
+
+.. [#f2]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.
+   The rest should be evident.

+Video Inputs and Outputs
+************************
+
+Video inputs and outputs are physical connectors of a device. These can
+be for example: RF connectors (antenna/cable), CVBS a.k.a. Composite
+Video, S-Video and RGB connectors. Camera sensors are also considered to
+be a video input. Video and VBI capture devices have inputs. Video and
+VBI output devices have outputs, at least one each. Radio devices have
+no video inputs or outputs.
+
+To learn about the number and attributes of the available inputs and
+outputs applications can enumerate them with the
+:ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` ioctl, respectively. The
+struct :c:type:`v4l2_input` returned by the
+:ref:`VIDIOC_ENUMINPUT` ioctl also contains signal
+status information applicable when the current video input is queried.
+
+The :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` ioctls return the index of
+the current video input or output. To select a different input or output
+applications call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` ioctls. Drivers must
+implement all the input ioctls when the device has one or more inputs,
+all the output ioctls when the device has one or more outputs.
+
+Example: Information about the current video input
+==================================================
+
+.. code-block:: c
+
+    struct v4l2_input input;
+    int index;
+
+    if (-1 == ioctl(fd, VIDIOC_G_INPUT, &index)) {

+VIDIOC_CREATE_BUFS - Create buffers for Memory Mapped or User Pointer or DMA Buffer I/O
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_CREATE_BUFS, struct v4l2_create_buffers *argp )
+    :name: VIDIOC_CREATE_BUFS
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_create_buffers`.
+
+
+Description
+===========
+
+This ioctl is used to create buffers for :ref:`memory mapped <mmap>`
+or :ref:`user pointer <userp>` or :ref:`DMA buffer <dmabuf>` I/O. It
+can be used as an alternative or in addition to the
+:ref:`VIDIOC_REQBUFS` ioctl, when a tighter control
+over buffers is required. This ioctl can be called multiple times to
+create buffers of different sizes.
+
+To allocate the device buffers applications must initialize the relevant
+fields of the struct :c:type:`v4l2_create_buffers` structure. The
+``count`` field must be set to the number of requested buffers, the
+``memory`` field specifies the requested I/O method and the ``reserved``
+array must be zeroed.
+
+The ``format`` field specifies the image format that the buffers must be
+able to handle. The application has to fill in this struct
+:c:type:`v4l2_format`. Usually this will be done using the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctls to ensure that the
+requested format is supported by the driver. Based on the format's
+``type`` field the requested buffer size (for single-planar) or plane
+sizes (for multi-planar formats) will be used for the allocated buffers.
+The driver may return an error if the size(s) are not supported by the
+hardware (usually because they are too small).
+
+The buffers created by this ioctl will have as minimum size the size
+defined by the ``format.pix.sizeimage`` field (or the corresponding
+fields for other format types). Usually if the ``format.pix.sizeimage``
+field is less than the minimum required for the given format, then an
+error will be returned since drivers will typically not allow this. If
+it is larger, then the value will be used as-is. In other words, the
+driver may reject the requested size, but if it is accepted the driver
+will use it unchanged.
+
+When the ioctl is called with a pointer to this structure the driver
+will attempt to allocate up to the requested number of buffers and store
+the actual number allocated and the starting index in the ``count`` and
+the ``index`` fields respectively. On return ``count`` can be smaller
+than the number requested.

+	:ref:`VIDIOC_CREATE_BUFS` will set ``index`` to the current number of
+	created buffers, and it will check the validity of ``memory`` and
+	``format.type``. If those are invalid -1 is returned and errno is
+	set to ``EINVAL`` error code, otherwise :ref:`VIDIOC_CREATE_BUFS` returns
+	0. It will never set errno to ``EBUSY`` error code in this particular
+	case.

+      - ``memory``
+      - Applications set this field to ``V4L2_MEMORY_MMAP``,

+      - ``format``
+      - Filled in by the application, preserved by the driver.
+    * - __u32
+      - ``capabilities``
+      - Set by the driver. If 0, then the driver doesn't support
+        capabilities. In that case all you know is that the driver is
+	guaranteed to support ``V4L2_MEMORY_MMAP`` and *might* support
+	other :c:type:`v4l2_memory` types. It will not support any others
+	capabilities. See :ref:`here <v4l2-buf-capabilities>` for a list of the
+	capabilities.
+
+	If you want to just query the capabilities without making any
+	other changes, then set ``count`` to 0, ``memory`` to
+	``V4L2_MEMORY_MMAP`` and ``format.type`` to the buffer type.
+    * - __u32
+      - ``reserved``\ [7]
+      - A place holder for future extensions. Drivers and applications
+	must set the array to zero.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+ENOMEM
+    No memory to allocate buffers for :ref:`memory mapped <mmap>` I/O.
+
+EINVAL
+    The buffer type (``format.type`` field), requested I/O method
+    (``memory``) or format (``format`` field) is not valid.

+
+``argp``
+    Pointer to struct :c:type:`v4l2_cropcap`.
+
+
+Description
+===========
+
+Applications use this function to query the cropping limits, the pixel
+aspect of images and to calculate scale factors. They set the ``type``
+field of a v4l2_cropcap structure to the respective buffer (stream)
+type and call the :ref:`VIDIOC_CROPCAP` ioctl with a pointer to this
+structure. Drivers fill the rest of the structure. The results are
+constant except when switching the video standard. Remember this switch
+can occur implicit when switching the video input or output.
+
+This ioctl must be implemented for video capture or output devices that
+support cropping and/or scaling and/or have non-square pixels, and for
+overlay devices.

+    * - __u32
+      - ``type``
+      - Type of the data stream, set by the application. Only these types
+	are valid here: ``V4L2_BUF_TYPE_VIDEO_CAPTURE``, ``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``,
+	``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE`` and
+	``V4L2_BUF_TYPE_VIDEO_OVERLAY``. See :c:type:`v4l2_buf_type` and the note below.
+    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
+      - ``bounds``
+      - Defines the window within capturing or output is possible, this
+	may exclude for example the horizontal and vertical blanking
+	areas. The cropping rectangle cannot exceed these limits. Width
+	and height are defined in pixels, the driver writer is free to
+	choose origin and units of the coordinate system in the analog
+	domain.
+    * - struct :ref:`v4l2_rect <v4l2-rect-crop>`
+      - ``defrect``
+      - Default cropping rectangle, it shall cover the "whole picture".
+	Assuming pixel aspect 1/1 this could be for example a 640 × 480
+	rectangle for NTSC, a 768 × 576 rectangle for PAL and SECAM
+	centered over the active picture area. The same co-ordinate system
+	as for ``bounds`` is used.
+    * - struct :c:type:`v4l2_fract`
+      - ``pixelaspect``
+      - This is the pixel aspect (y / x) when no scaling is applied, the
+	ratio of the actual sampling frequency and the frequency required
+	to get square pixels.
+
+	When cropping coordinates refer to square pixels, the driver sets
+	``pixelaspect`` to 1/1. Other common values are 54/59 for PAL and
+	SECAM, 11/10 for NTSC sampled according to [:ref:`itu601`].
+
+.. note::
+   Unfortunately in the case of multiplanar buffer types
+   (``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``)
+   this API was messed up with regards to how the :c:type:`v4l2_cropcap` ``type`` field
+   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
+   other drivers only accepted a non-multiplanar buffer type (i.e. without the
+   ``_MPLANE`` at the end).
+
+   Starting with kernel 4.13 both variations are allowed.

+    :name: VIDIOC_DBG_G_CHIP_INFO
+

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_dbg_chip_info`.
+
+
+Description
+===========
+
+.. note::
+
+    This is an :ref:`experimental` interface and may
+    change in the future.
+
+For driver debugging purposes this ioctl allows test applications to
+query the driver about the chips present on the TV card. Regular
+applications must not use it. When you found a chip specific bug, please
+contact the linux-media mailing list
+(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__)
+so it can be fixed.
+
+Additionally the Linux kernel must be compiled with the
+``CONFIG_VIDEO_ADV_DEBUG`` option to enable this ioctl.
+
+To query the driver applications must initialize the ``match.type`` and
+``match.addr`` or ``match.name`` fields of a struct
+:c:type:`v4l2_dbg_chip_info` and call
+:ref:`VIDIOC_DBG_G_CHIP_INFO` with a pointer to this structure. On success
+the driver stores information about the selected chip in the ``name``
+and ``flags`` fields.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
+selects the nth bridge 'chip' on the TV card. You can enumerate all
+chips by starting at zero and incrementing ``match.addr`` by one until
+:ref:`VIDIOC_DBG_G_CHIP_INFO` fails with an ``EINVAL`` error code. The number
+zero always selects the bridge chip itself, e. g. the chip connected to
+the PCI or USB bus. Non-zero numbers identify specific parts of the
+bridge chip such as an AC97 register block.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
+selects the nth sub-device. This allows you to enumerate over all
+sub-devices.
+
+On success, the ``name`` field will contain a chip name and the
+``flags`` field will contain ``V4L2_CHIP_FL_READABLE`` if the driver
+supports reading registers from the device or ``V4L2_CHIP_FL_WRITABLE``
+if the driver supports writing registers to the device.
+
+We recommended the v4l2-dbg utility over calling this ioctl directly. It
+is available from the LinuxTV v4l-dvb repository; see
+`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access

+    :name: VIDIOC_DBG_S_REGISTER
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_dbg_register`.
+
+
+Description
+===========
+
+.. note::
+
+    This is an :ref:`experimental` interface and may
+    change in the future.
+
+For driver debugging purposes these ioctls allow test applications to
+access hardware registers directly. Regular applications must not use
+them.
+
+Since writing or even reading registers can jeopardize the system
+security, its stability and damage the hardware, both ioctls require
+superuser privileges. Additionally the Linux kernel must be compiled
+with the ``CONFIG_VIDEO_ADV_DEBUG`` option to enable these ioctls.
+
+To write a register applications must initialize all fields of a struct
+:c:type:`v4l2_dbg_register` except for ``size`` and
+call ``VIDIOC_DBG_S_REGISTER`` with a pointer to this structure. The
+``match.type`` and ``match.addr`` or ``match.name`` fields select a chip
+on the TV card, the ``reg`` field specifies a register number and the
+``val`` field the value to be written into the register.
+
+To read a register applications must initialize the ``match.type``,
+``match.addr`` or ``match.name`` and ``reg`` fields, and call
+``VIDIOC_DBG_G_REGISTER`` with a pointer to this structure. On success
+the driver stores the register value in the ``val`` field and the size
+(in bytes) of the value in ``size``.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
+selects the nth non-sub-device chip on the TV card. The number zero
+always selects the host chip, e. g. the chip connected to the PCI or USB
+bus. You can find out which chips are present with the
+:ref:`VIDIOC_DBG_G_CHIP_INFO` ioctl.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
+selects the nth sub-device.
+
+These ioctls are optional, not all drivers may support them. However
+when a driver supports these ioctls it must also support
+:ref:`VIDIOC_DBG_G_CHIP_INFO`. Conversely
+it may support ``VIDIOC_DBG_G_CHIP_INFO`` but not these ioctls.
+
+``VIDIOC_DBG_G_REGISTER`` and ``VIDIOC_DBG_S_REGISTER`` were introduced
+in Linux 2.6.21, but their API was changed to the one described here in
+kernel 2.6.29.
+
+We recommended the v4l2-dbg utility over calling these ioctls directly.
+It is available from the LinuxTV v4l-dvb repository; see
+`https://linuxtv.org/repo/ <https://linuxtv.org/repo/>`__ for access
+instructions.

+    pointer to struct :c:type:`v4l2_decoder_cmd`.
+
+
+Description
+===========
+
+These ioctls control an audio/video (usually MPEG-) decoder.
+``VIDIOC_DECODER_CMD`` sends a command to the decoder,
+``VIDIOC_TRY_DECODER_CMD`` can be used to try a command without actually
+executing it. To send a command applications must initialize all fields
+of a struct :c:type:`v4l2_decoder_cmd` and call
+``VIDIOC_DECODER_CMD`` or ``VIDIOC_TRY_DECODER_CMD`` with a pointer to
+this structure.
+
+The ``cmd`` field must contain the command code. Some commands use the
+``flags`` field for additional information.
+
+A :ref:`write() <func-write>` or :ref:`VIDIOC_STREAMON`
+call sends an implicit START command to the decoder if it has not been
+started yet. Applies to both queues of mem2mem decoders.
+
+A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+call of a streaming file descriptor sends an implicit immediate STOP
+command to the decoder, and all buffered data is discarded. Applies to both
+queues of mem2mem decoders.
+
+In principle, these ioctls are optional, not all drivers may support them. They were
+introduced in Linux 3.3. They are, however, mandatory for stateful mem2mem decoders
+(as further documented in :ref:`decoder`).

+    * -
+      - __s32
+      - ``speed``
+      - Playback speed and direction. The playback speed is defined as
+	``speed``/1000 of the normal speed. So 1000 is normal playback.
+	Negative numbers denote reverse playback, so -1000 does reverse
+	playback at normal speed. Speeds -1, 0 and 1 have special
+	meanings: speed 0 is shorthand for 1000 (normal playback). A speed
+	of 1 steps just one frame forward, a speed of -1 steps just one
+	frame back.
+    * -
+      - __u32
+      - ``format``
+      - Format restrictions. This field is set by the driver, not the
+	application. Possible values are ``V4L2_DEC_START_FMT_NONE`` if
+	there are no format restrictions or ``V4L2_DEC_START_FMT_GOP`` if
+	the decoder operates on full GOPs (*Group Of Pictures*). This is
+	usually the case for reverse playback: the decoder needs full
+	GOPs, which it can then play in reverse order. So to implement
+	reverse playback the application must feed the decoder the last
+	GOP in the video file, then the GOP before that, etc. etc.
+    * - struct

+      - ``data``\ [16]

+
+    * - ``V4L2_DEC_CMD_START``
+      - 0
+      - Start the decoder. When the decoder is already running or paused,
+	this command will just change the playback speed. That means that
+	calling ``V4L2_DEC_CMD_START`` when the decoder was paused will
+	*not* resume the decoder. You have to explicitly call
+	``V4L2_DEC_CMD_RESUME`` for that. This command has one flag:
+	``V4L2_DEC_CMD_START_MUTE_AUDIO``. If set, then audio will be
+	muted when playing back at a non-standard speed.
+
+	For a device implementing the :ref:`decoder`, once the drain sequence
+	is initiated with the ``V4L2_DEC_CMD_STOP`` command, it must be driven
+	to completion before this command can be invoked.  Any attempt to
+	invoke the command while the drain sequence is in progress will trigger
+	an ``EBUSY`` error code.  The command may be also used to restart the
+	decoder in case of an implicit stop initiated by the decoder itself,
+	without the ``V4L2_DEC_CMD_STOP`` being called explicitly. See
+	:ref:`decoder` for more details.
+    * - ``V4L2_DEC_CMD_STOP``
+      - 1
+      - Stop the decoder. When the decoder is already stopped, this
+	command does nothing. This command has two flags: if
+	``V4L2_DEC_CMD_STOP_TO_BLACK`` is set, then the decoder will set
+	the picture to black after it stopped decoding. Otherwise the last
+	image will repeat. If
+	``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops
+	immediately (ignoring the ``pts`` value), otherwise it will keep
+	decoding until timestamp >= pts or until the last of the pending
+	data from its internal buffers was decoded.
+
+	For a device implementing the :ref:`decoder`, the command will initiate
+	the drain sequence as documented in :ref:`decoder`.  No flags or other
+	arguments are accepted in this case. Any attempt to invoke the command
+	again before the sequence completes will trigger an ``EBUSY`` error
+	code.
+    * - ``V4L2_DEC_CMD_PAUSE``
+      - 2
+      - Pause the decoder. When the decoder has not been started yet, the
+	driver will return an ``EPERM`` error code. When the decoder is
+	already paused, this command does nothing. This command has one
+	flag: if ``V4L2_DEC_CMD_PAUSE_TO_BLACK`` is set, then set the
+	decoder output to black when paused.
+    * - ``V4L2_DEC_CMD_RESUME``
+      - 3
+      - Resume decoding after a PAUSE command. When the decoder has not
+	been started yet, the driver will return an ``EPERM`` error code. When
+	the decoder is already running, this command does nothing. No
+	flags are defined for this command.
+    * - ``V4L2_DEC_CMD_FLUSH``
+      - 4
+      - Flush any held capture buffers. Only valid for stateless decoders.
+	This command is typically used when the application reached the
+	end of the stream and the last output buffer had the
+	``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag set. This would prevent
+	dequeueing the capture buffer containing the last decoded frame.
+	So this command can be used to explicitly flush that final decoded
+	frame. This command does nothing if there are no held capture buffers.
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+    A drain sequence of a device implementing the :ref:`decoder` is still in

+	This event type will ensure that no information is lost when more
+	events are raised than there is room internally. In that case the
+	struct :c:type:`v4l2_event_ctrl` of the
+	second-oldest event is kept, but the ``changes`` field of the
+	second-oldest event is ORed with the ``changes`` field of the
+	oldest event.
+    * - ``V4L2_EVENT_FRAME_SYNC``
+      - 4
+      - Triggered immediately when the reception of a frame has begun.
+	This event has a struct
+	:c:type:`v4l2_event_frame_sync`
+	associated with it.
+
+	If the hardware needs to be stopped in the case of a buffer
+	underrun it might not be able to generate this event. In such
+	cases the ``frame_sequence`` field in struct
+	:c:type:`v4l2_event_frame_sync` will not
+	be incremented. This causes two consecutive frame sequence numbers
+	to have n times frame interval in between them.
+    * - ``V4L2_EVENT_SOURCE_CHANGE``
+      - 5
+      - This event is triggered when a source parameter change is detected
+	during runtime by the video device. It can be a runtime resolution
+	change triggered by a video decoder or the format change happening
+	on an input connector. This event requires that the ``id`` matches
+	the input index (when used with a video device node) or the pad
+	index (when used with a subdevice node) from which you want to
+	receive events.
+
+	This event has a struct
+	:c:type:`v4l2_event_src_change`
+	associated with it. The ``changes`` bitfield denotes what has
+	changed for the subscribed pad. If multiple events occurred before
+	application could dequeue them, then the changes will have the
+	ORed value of all the events generated.
+    * - ``V4L2_EVENT_MOTION_DET``
+      - 6
+      - Triggered whenever the motion detection state for one or more of
+	the regions changes. This event has a struct
+	:c:type:`v4l2_event_motion_det`
+	associated with it.
+    * - ``V4L2_EVENT_PRIVATE_START``

+
+
+Description
+===========
+
+To query the capabilities of the DV receiver/transmitter applications
+initialize the ``pad`` field to 0, zero the reserved array of struct
+:c:type:`v4l2_dv_timings_cap` and call the
+``VIDIOC_DV_TIMINGS_CAP`` ioctl on a video node and the driver will fill
+in the structure.
+
+.. note::
+
+   Drivers may return different values after
+   switching the video input or output.
+
+When implemented by the driver DV capabilities of subdevices can be
+queried by calling the ``VIDIOC_SUBDEV_DV_TIMINGS_CAP`` ioctl directly
+on a subdevice node. The capabilities are specific to inputs (for DV
+receivers) or outputs (for DV transmitters), applications must specify
+the desired pad number in the struct
+:c:type:`v4l2_dv_timings_cap` ``pad`` field and
+zero the ``reserved`` array. Attempts to query capabilities on a pad
+that doesn't support them will return an ``EINVAL`` error code.

+
+``fd``

+
+``argp``
+    Pointer to struct :c:type:`v4l2_encoder_cmd`.
+
+Description
+===========
+
+These ioctls control an audio/video (usually MPEG-) encoder.
+``VIDIOC_ENCODER_CMD`` sends a command to the encoder,
+``VIDIOC_TRY_ENCODER_CMD`` can be used to try a command without actually
+executing it.
+
+To send a command applications must initialize all fields of a struct
+:c:type:`v4l2_encoder_cmd` and call
+``VIDIOC_ENCODER_CMD`` or ``VIDIOC_TRY_ENCODER_CMD`` with a pointer to
+this structure.
+
+The ``cmd`` field must contain the command code. The ``flags`` field is
+currently only used by the STOP command and contains one bit: If the
+``V4L2_ENC_CMD_STOP_AT_GOP_END`` flag is set, encoding will continue
+until the end of the current *Group Of Pictures*, otherwise it will stop
+immediately.
+
+A :ref:`read() <func-read>` or :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+call sends an implicit START command to the encoder if it has not been
+started yet. After a STOP command, :ref:`read() <func-read>` calls will read
+the remaining data buffered by the driver. When the buffer is empty,
+:ref:`read() <func-read>` will return zero and the next :ref:`read() <func-read>`
+call will restart the encoder.
+
+A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+call of a streaming file descriptor sends an implicit immediate STOP to
+the encoder, and all buffered data is discarded.
+
+These ioctls are optional, not all drivers may support them. They were
+introduced in Linux 2.6.21.

+      - Stop the encoder. When the ``V4L2_ENC_CMD_STOP_AT_GOP_END`` flag
+	is set, encoding will continue until the end of the current *Group
+	Of Pictures*, otherwise encoding will stop immediately. When the
+	encoder is already stopped, this command does nothing. mem2mem

+	set the ``V4L2_BUF_FLAG_LAST`` buffer flag on the last buffer of
+	the capture queue to indicate there will be no new buffers
+	produced to dequeue. This buffer may be empty, indicated by the
+	driver setting the ``bytesused`` field to 0. Once the

+    * - ``V4L2_ENC_CMD_RESUME``
+      - 3
+      - Resume encoding after a PAUSE command. When the encoder has not

+
+Description
+===========
+
+While some DV receivers or transmitters support a wide range of timings,
+others support only a limited number of timings. With this ioctl
+applications can enumerate a list of known supported timings. Call
+:ref:`VIDIOC_DV_TIMINGS_CAP` to check if it
+also supports other standards or even custom timings that are not in
+this list.
+
+To query the available timings, applications initialize the ``index``
+field, set the ``pad`` field to 0, zero the reserved array of struct
+:c:type:`v4l2_enum_dv_timings` and call the
+``VIDIOC_ENUM_DV_TIMINGS`` ioctl on a video node with a pointer to this
+structure. Drivers fill the rest of the structure or return an ``EINVAL``
+error code when the index is out of bounds. To enumerate all supported
+DV timings, applications shall begin at index zero, incrementing by one
+until the driver returns ``EINVAL``.
+
+.. note::
+
+   Drivers may enumerate a different set of DV timings after
+   switching the video input or output.
+
+When implemented by the driver DV timings of subdevices can be queried
+by calling the ``VIDIOC_SUBDEV_ENUM_DV_TIMINGS`` ioctl directly on a
+subdevice node. The DV timings are specific to inputs (for DV receivers)
+or outputs (for DV transmitters), applications must specify the desired
+pad number in the struct
+:c:type:`v4l2_enum_dv_timings` ``pad`` field.
+Attempts to enumerate timings on a pad that doesn't support them will
+return an ``EINVAL`` error code.

+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_ENUM_FRAMEINTERVALS, struct v4l2_frmivalenum *argp )
+    :name: VIDIOC_ENUM_FRAMEINTERVALS
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_frmivalenum`
+    that contains a pixel format and size and receives a frame interval.
+
+
+Description
+===========
+
+This ioctl allows applications to enumerate all frame intervals that the
+device supports for the given pixel format and frame size.
+
+The supported pixel formats and frame sizes can be obtained by using the
+:ref:`VIDIOC_ENUM_FMT` and
+:ref:`VIDIOC_ENUM_FRAMESIZES` functions.
+
+The return value and the content of the ``v4l2_frmivalenum.type`` field
+depend on the type of frame intervals the device supports. Here are the
+semantics of the function for the different cases:
+
+-  **Discrete:** The function returns success if the given index value
+   (zero-based) is valid. The application should increase the index by
+   one for each call until ``EINVAL`` is returned. The
+   `v4l2_frmivalenum.type` field is set to
+   `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the union only
+   the `discrete` member is valid.
+
+-  **Step-wise:** The function returns success if the given index value
+   is zero and ``EINVAL`` for any other index value. The
+   ``v4l2_frmivalenum.type`` field is set to
+   ``V4L2_FRMIVAL_TYPE_STEPWISE`` by the driver. Of the union only the
+   ``stepwise`` member is valid.
+
+-  **Continuous:** This is a special case of the step-wise type above.
+   The function returns success if the given index value is zero and
+   ``EINVAL`` for any other index value. The ``v4l2_frmivalenum.type``
+   field is set to ``V4L2_FRMIVAL_TYPE_CONTINUOUS`` by the driver. Of
+   the union only the ``stepwise`` member is valid and the ``step``
+   value is set to 1.
+
+When the application calls the function with index zero, it must check
+the ``type`` field to determine the type of frame interval enumeration
+the device supports. Only for the ``V4L2_FRMIVAL_TYPE_DISCRETE`` type
+does it make sense to increase the index value to receive more frame
+intervals.
+
+.. note::
+
+   The order in which the frame intervals are returned has no
+   special meaning. In particular does it not say anything about potential
+   default frame intervals.
+
+Applications can assume that the enumeration data does not change
+without any interaction from the application itself. This means that the
+enumeration data is consistent if the application does not perform any
+other ioctl calls while it runs the frame interval enumeration.
+
+.. note::
+
+   **Frame intervals and frame rates:** The V4L2 API uses frame
+   intervals instead of frame rates. Given the frame interval the frame
+   rate can be computed as follows:
+
+   ::
+
+       frame_rate = 1 / frame_interval

+===========
+
+Enumerates the frequency bands that a tuner or modulator supports. To do
+this applications initialize the ``tuner``, ``type`` and ``index``
+fields, and zero out the ``reserved`` array of a struct
+:c:type:`v4l2_frequency_band` and call the

+
+This ioctl is supported if the ``V4L2_TUNER_CAP_FREQ_BANDS`` capability
+of the corresponding tuner/modulator is set.

+Description
+===========
+
+To query the attributes of a video outputs applications initialize the
+``index`` field of struct :c:type:`v4l2_output` and call
+the :ref:`VIDIOC_ENUMOUTPUT` with a pointer to this structure.
+Drivers fill the rest of the structure or return an ``EINVAL`` error code
+when the index is out of bounds. To enumerate all outputs applications
+shall begin at index zero, incrementing by one until the driver returns
+``EINVAL``.

+      - Name of the video output, a NUL-terminated ASCII string, for
+	example: "Vout". This information is intended for the user,

+      - ``type``
+      - Type of the output, see :ref:`output-type`.
+    * - __u32
+      - ``audioset``
+      - Drivers can enumerate up to 32 video and audio outputs. This field
+	shows which audio outputs were selectable as the current output if
+	this was the currently selected video output. It is a bit mask.
+	The LSB corresponds to audio output 0, the MSB to output 31. Any
+	number of bits can be set, or none.
+
+	When the driver does not enumerate audio outputs no bits must be
+	set. Applications shall not interpret this as lack of audio
+	support. Drivers may automatically select audio outputs without
+	enumerating them.
+
+	For details on audio outputs and how to select the current output
+	see :ref:`audio`.
+    * - __u32
+      - ``modulator``
+      - Output devices can have zero or more RF modulators. When the
+	``type`` is ``V4L2_OUTPUT_TYPE_MODULATOR`` this is an RF connector
+	and this field identifies the modulator. It corresponds to struct
+	:c:type:`v4l2_modulator` field ``index``. For
+	details on modulators see :ref:`tuner`.
+    * - :ref:`v4l2_std_id <v4l2-std-id>`
+      - ``std``
+      - Every video output supports one or more different video standards.
+	This field is a set of all supported standards. For details on
+	video standards and how to switch see :ref:`standard`.
+    * - __u32
+      - ``capabilities``
+      - This field provides capabilities for the output. See
+	:ref:`output-capabilities` for flags.
+    * - __u32
+      - ``reserved``\ [3]
+      - Reserved for future extensions. Drivers must set the array to

+Description
+===========
+
+To query the attributes of a video standard, especially a custom (driver
+defined) one, applications initialize the ``index`` field of struct
+:c:type:`v4l2_standard` and call the :ref:`VIDIOC_ENUMSTD`
+ioctl with a pointer to this structure. Drivers fill the rest of the
+structure or return an ``EINVAL`` error code when the index is out of
+bounds. To enumerate all standards applications shall begin at index
+zero, incrementing by one until the driver returns ``EINVAL``. Drivers may
+enumerate a different set of standards after switching the video input
+or output. [#f1]_

+
+    * - __u32
+      - ``index``
+      - Number of the video standard, set by the application.
+    * - :ref:`v4l2_std_id <v4l2-std-id>`
+      - ``id``
+      - The bits in this field identify the standard as one of the common
+	standards listed in :ref:`v4l2-std-id`, or if bits 32 to 63 are
+	set as custom standards. Multiple bits can be set if the hardware
+	does not distinguish between these standards, however separate
+	indices do not indicate the opposite. The ``id`` must be unique.
+	No other enumerated struct :c:type:`v4l2_standard` structure,
+	for this input or output anyway, can contain the same set of bits.
+    * - __u8
+      - ``name``\ [24]
+      - Name of the standard, a NUL-terminated ASCII string, for example:

+	user.
+    * - struct :c:type:`v4l2_fract`
+      - ``frameperiod``
+      - The frame period (not field period) is numerator / denominator.
+	For example M/NTSC has a frame period of 1001 / 30000 seconds.
+    * - __u32
+      - ``framelines``

+
+VIDIOC_EXPBUF - Export a buffer as a DMABUF file descriptor.
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_EXPBUF, struct v4l2_exportbuffer *argp )
+    :name: VIDIOC_EXPBUF
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_exportbuffer`.
+
+
+Description
+===========
+
+This ioctl is an extension to the :ref:`memory mapping <mmap>` I/O
+method, therefore it is available only for ``V4L2_MEMORY_MMAP`` buffers.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the
+:ref:`VIDIOC_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct
+:c:type:`v4l2_exportbuffer`. The ``type`` field is
+set to the same buffer type as was previously used with struct
+:c:type:`v4l2_requestbuffers` ``type``.
+Applications must also set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:c:type:`v4l2_requestbuffers` ``count``) minus
+one. For the multi-planar API, applications set the ``plane`` field to
+the index of the plane to be exported. Valid planes range from zero to
+the maximal number of valid planes for the currently active format. For
+the single-planar API, applications must set ``plane`` to zero.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported. All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`VIDIOC_EXPBUF` calls.
+
+After calling :ref:`VIDIOC_EXPBUF` the ``fd`` field will be set by a
+driver. This is a DMABUF file descriptor. The application may pass it to
+other DMABUF-aware devices. Refer to :ref:`DMABUF importing <dmabuf>`
+for details about importing DMABUF files into V4L2 nodes. It is
+recommended to close a DMABUF file when it is no longer used to allow
+the associated memory to be reclaimed.

+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_crop`.
+
+
+Description
+===========
+
+To query the cropping rectangle size and position applications set the
+``type`` field of a struct :c:type:`v4l2_crop` structure to the
+respective buffer (stream) type and call the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` ioctl
+with a pointer to this structure. The driver fills the rest of the
+structure or returns the ``EINVAL`` error code if cropping is not supported.
+
+To change the cropping rectangle applications initialize the ``type``
+and struct :c:type:`v4l2_rect` substructure named ``c`` of a
+v4l2_crop structure and call the :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl with a pointer
+to this structure.
+
+The driver first adjusts the requested dimensions against hardware
+limits, i. e. the bounds given by the capture/output window, and it
+rounds to the closest possible values of horizontal and vertical offset,
+width and height. In particular the driver must round the vertical
+offset of the cropping rectangle to frame lines modulo two, such that
+the field order cannot be confused.
+
+Second the driver adjusts the image size (the opposite rectangle of the
+scaling process, source or target depending on the data direction) to
+the closest size possible while maintaining the current horizontal and
+vertical scaling factor.
+
+Finally the driver programs the hardware with the actual cropping and
+image parameters. :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` is a write-only ioctl, it does not
+return the actual parameters. To query them applications must call
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_G_FMT`. When the
+parameters are unsuitable the application may modify the cropping or
+image parameters and repeat the cycle until satisfactory parameters have
+been negotiated.
+
+When cropping is not supported then no parameters are changed and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` returns the ``EINVAL`` error code.

+   Unfortunately in the case of multiplanar buffer types
+   (``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``)
+   this API was messed up with regards to how the :c:type:`v4l2_crop` ``type`` field
+   should be filled in. Some drivers only accepted the ``_MPLANE`` buffer type while
+   other drivers only accepted a non-multiplanar buffer type (i.e. without the
+   ``_MPLANE`` at the end).
+
+   Starting with kernel 4.13 both variations are allowed.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_control`.
+
+
+Description
+===========
+
+To get the current value of a control applications initialize the ``id``
+field of a struct :c:type:`v4l2_control` and call the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` ioctl with a pointer to this structure. To change the
+value of a control applications initialize the ``id`` and ``value``
+fields of a struct :c:type:`v4l2_control` and call the
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctl.
+
+When the ``id`` is invalid drivers return an ``EINVAL`` error code. When the
+``value`` is out of bounds drivers can choose to take the closest valid
+value or return an ``ERANGE`` error code, whatever seems more appropriate.
+However, :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` is a write-only ioctl, it does not return the
+actual new value. If the ``value`` is inappropriate for the control
+(e.g. if it refers to an unsupported menu index of a menu control), then
+EINVAL error code is returned as well.
+
+These ioctls work only with user controls. For other control classes the
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` or
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` must be used.

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_dv_timings`.
+
+
+Description
+===========
+
+To set DV timings for the input or output, applications use the
+:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get the current timings,
+applications use the :ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. The detailed timing
+information is filled in using the structure struct
+:c:type:`v4l2_dv_timings`. These ioctls take a
+pointer to the struct :c:type:`v4l2_dv_timings`
+structure as argument. If the ioctl is not supported or the timing
+values are not correct, the driver returns ``EINVAL`` error code.
+
+The ``linux/v4l2-dv-timings.h`` header can be used to get the timings of
+the formats in the :ref:`cea861` and :ref:`vesadmt` standards. If
+the current input or output does not support DV timings (e.g. if
+:ref:`VIDIOC_ENUMINPUT` does not set the
+``V4L2_IN_CAP_DV_TIMINGS`` flag), then ``ENODATA`` error code is returned.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    This ioctl is not supported, or the :ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>`
+    parameter was unsuitable.
+
+ENODATA
+    Digital video timings are not supported for this input or output.
+
+EBUSY
+    The device is busy and therefore can not change the timings.

+	'Secondary GTF' curve (GTF). In both cases the horizontal and/or
+	vertical blanking intervals are reduced, allowing a higher
+	resolution over the same bandwidth. This is a read-only flag,
+	applications must not set this.
+    * - ``V4L2_DV_FL_CAN_REDUCE_FPS``
+      - CEA-861 specific: set for CEA-861 formats with a framerate that is
+	a multiple of six. These formats can be optionally played at 1 /
+	1.001 speed to be compatible with 60 Hz based standards such as
+	NTSC and PAL-M that use a framerate of 29.97 frames per second. If
+	the transmitter can't generate such frequencies, then the flag
+	will also be cleared. This is a read-only flag, applications must
+	not set this.
+    * - ``V4L2_DV_FL_REDUCED_FPS``
+      - CEA-861 specific: only valid for video transmitters or video
+        receivers that have the ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
+	set. This flag is cleared otherwise. It is also only valid for
+	formats with the ``V4L2_DV_FL_CAN_REDUCE_FPS`` flag set, for other
+	formats the flag will be cleared by the driver.
+
+	If the application sets this flag for a transmitter, then the
+	pixelclock used to set up the transmitter is divided by 1.001 to
+	make it compatible with NTSC framerates. If the transmitter can't
+	generate such frequencies, then the flag will be cleared.
+
+	If a video receiver detects that the format uses a reduced framerate,
+	then it will set this flag to signal this to the application.
+    * - ``V4L2_DV_FL_HALF_LINE``
+      - Specific to interlaced formats: if set, then the vertical
+	frontporch of field 1 (aka the odd field) is really one half-line
+	longer and the vertical backporch of field 2 (aka the even field)
+	is really one half-line shorter, so each field has exactly the
+	same number of half-lines. Whether half-lines can be detected or
+	used depends on the hardware.
+    * - ``V4L2_DV_FL_IS_CE_VIDEO``
+      - If set, then this is a Consumer Electronics (CE) video format.
+	Such formats differ from other formats (commonly called IT
+	formats) in that if R'G'B' encoding is used then by default the
+	R'G'B' values use limited range (i.e. 16-235) as opposed to full
+	range (i.e. 0-255). All formats defined in CEA-861 except for the
+	640x480p59.94 format are CE formats.
+    * - ``V4L2_DV_FL_FIRST_FIELD_EXTRA_LINE``
+      - Some formats like SMPTE-125M have an interlaced signal with a odd
+	total height. For these formats, if this flag is set, the first
+	field has the extra line. Else, it is the second field.
+    * - ``V4L2_DV_FL_HAS_PICTURE_ASPECT``
+      - If set, then the picture_aspect field is valid. Otherwise assume that
+        the pixels are square, so the picture aspect ratio is the same as the
+	width to height ratio.
+    * - ``V4L2_DV_FL_HAS_CEA861_VIC``
+      - If set, then the cea861_vic field is valid and contains the Video
+        Identification Code as per the CEA-861 standard.
+    * - ``V4L2_DV_FL_HAS_HDMI_VIC``
+      - If set, then the hdmi_vic field is valid and contains the Video
+        Identification Code as per the HDMI standard (HDMI Vendor Specific
+	InfoFrame).
+    * - ``V4L2_DV_FL_CAN_DETECT_REDUCED_FPS``
+      - CEA-861 specific: only valid for video receivers, the flag is
+        cleared by transmitters.
+        If set, then the hardware can detect the difference between
+	regular framerates and framerates reduced by 1000/1001. E.g.:
+	60 vs 59.94 Hz, 30 vs 29.97 Hz or 24 vs 23.976 Hz.

+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+   Pointer to struct :c:type:`v4l2_edid`.
+
+
+Description
+===========
+
+These ioctls can be used to get or set an EDID associated with an input
+from a receiver or an output of a transmitter device. They can be used
+with subdevice nodes (/dev/v4l-subdevX) or with video nodes
+(/dev/videoX).
+
+When used with video nodes the ``pad`` field represents the input (for
+video capture devices) or output (for video output devices) index as is
+returned by :ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` respectively. When used
+with subdevice nodes the ``pad`` field represents the input or output
+pad of the subdevice. If there is no EDID support for the given ``pad``
+value, then the ``EINVAL`` error code will be returned.
+
+To get the EDID data the application has to fill in the ``pad``,
+``start_block``, ``blocks`` and ``edid`` fields, zero the ``reserved``
+array and call :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>`. The current EDID from block
+``start_block`` and of size ``blocks`` will be placed in the memory
+``edid`` points to. The ``edid`` pointer must point to memory at least
+``blocks`` * 128 bytes large (the size of one block is 128 bytes).
+
+If there are fewer blocks than specified, then the driver will set
+``blocks`` to the actual number of blocks. If there are no EDID blocks
+available at all, then the error code ``ENODATA`` is set.
+
+If blocks have to be retrieved from the sink, then this call will block
+until they have been read.
+
+If ``start_block`` and ``blocks`` are both set to 0 when
+:ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>` is called, then the driver will set ``blocks`` to the
+total number of available EDID blocks and it will return 0 without
+copying any data. This is an easy way to discover how many EDID blocks
+there are.
+
+.. note::
+
+   If there are no EDID blocks available at all, then
+   the driver will set ``blocks`` to 0 and it returns 0.
+
+To set the EDID blocks of a receiver the application has to fill in the
+``pad``, ``blocks`` and ``edid`` fields, set ``start_block`` to 0 and
+zero the ``reserved`` array. It is not possible to set part of an EDID,
+it is always all or nothing. Setting the EDID data is only valid for
+receivers as it makes no sense for a transmitter.
+
+The driver assumes that the full EDID is passed in. If there are more
+EDID blocks than the hardware can handle then the EDID is not written,
+but instead the error code ``E2BIG`` is set and ``blocks`` is set to the
+maximum that the hardware supports. If ``start_block`` is any value
+other than 0 then the error code ``EINVAL`` is set.
+
+To disable an EDID you set ``blocks`` to 0. Depending on the hardware
+this will drive the hotplug pin low and/or block the source from reading
+the EDID data in some way. In any case, the end result is the same: the
+EDID is no longer available.

+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_enc_idx`.
+
+
+Description
+===========
+
+The :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` ioctl provides meta data about a compressed
+video stream the same or another application currently reads from the
+driver, which is useful for random access into the stream without
+decoding it.
+
+To read the data applications must call :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` with a
+pointer to a struct :c:type:`v4l2_enc_idx`. On success
+the driver fills the ``entry`` array, stores the number of elements
+written in the ``entries`` field, and initializes the ``entries_cap``
+field.
+
+Each element of the ``entry`` array contains meta data about one
+picture. A :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` call reads up to
+``V4L2_ENC_IDX_ENTRIES`` entries from a driver buffer, which can hold up
+to ``entries_cap`` entries. This number can be lower or higher than
+``V4L2_ENC_IDX_ENTRIES``, but not zero. When the application fails to
+read the meta data in time the oldest entries will be lost. When the
+buffer is empty or no capturing/encoding is in progress, ``entries``
+will be zero.
+
+Currently this ioctl is only defined for MPEG-2 program streams and
+video elementary streams.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_ext_controls`.
+
+
+Description
+===========
+
+These ioctls allow the caller to get or set multiple controls
+atomically. Control IDs are grouped into control classes (see
+:ref:`ctrl-class`) and all controls in the control array must belong
+to the same control class.
+
+Applications must always fill in the ``count``, ``which``, ``controls``
+and ``reserved`` fields of struct
+:c:type:`v4l2_ext_controls`, and initialize the
+struct :c:type:`v4l2_ext_control` array pointed to
+by the ``controls`` fields.
+
+To get the current value of a set of controls applications initialize
+the ``id``, ``size`` and ``reserved2`` fields of each struct
+:c:type:`v4l2_ext_control` and call the
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. String controls controls must also set the
+``string`` field. Controls of compound types
+(``V4L2_CTRL_FLAG_HAS_PAYLOAD`` is set) must set the ``ptr`` field.
+
+If the ``size`` is too small to receive the control result (only
+relevant for pointer-type controls like strings), then the driver will
+set ``size`` to a valid value and return an ``ENOSPC`` error code. You
+should re-allocate the memory to this new size and try again. For the
+string type it is possible that the same issue occurs again if the
+string has grown in the meantime. It is recommended to call
+:ref:`VIDIOC_QUERYCTRL` first and use
+``maximum``\ +1 as the new ``size`` value. It is guaranteed that that is
+sufficient memory.
+
+N-dimensional arrays are set and retrieved row-by-row. You cannot set a
+partial array, all elements have to be set or retrieved. The total size
+is calculated as ``elems`` * ``elem_size``. These values can be obtained
+by calling :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>`.
+
+To change the value of a set of controls applications initialize the
+``id``, ``size``, ``reserved2`` and ``value/value64/string/ptr`` fields
+of each struct :c:type:`v4l2_ext_control` and call
+the :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. The controls will only be set if *all*
+control values are valid.
+
+To check if a set of controls have correct values applications
+initialize the ``id``, ``size``, ``reserved2`` and
+``value/value64/string/ptr`` fields of each struct
+:c:type:`v4l2_ext_control` and call the
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. It is up to the driver whether wrong
+values are automatically adjusted to a valid value or if an error is
+returned.
+
+When the ``id`` or ``which`` is invalid drivers return an ``EINVAL`` error
+code. When the value is out of bounds drivers can choose to take the
+closest valid value or return an ``ERANGE`` error code, whatever seems more
+appropriate. In the first case the new value is set in struct
+:c:type:`v4l2_ext_control`. If the new control value
+is inappropriate (e.g. the given menu index is not supported by the menu
+control), then this will also result in an ``EINVAL`` error code error.
+
+If ``request_fd`` is set to a not-yet-queued :ref:`request <media-request-api>`
+file descriptor and ``which`` is set to ``V4L2_CTRL_WHICH_REQUEST_VAL``,
+then the controls are not applied immediately when calling
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, but instead are applied by
+the driver for the buffer associated with the same request.
+If the device does not support requests, then ``EACCES`` will be returned.
+If requests are supported but an invalid request file descriptor is given,
+then ``EINVAL`` will be returned.
+
+An attempt to call :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` for a
+request that has already been queued will result in an ``EBUSY`` error.
+
+If ``request_fd`` is specified and ``which`` is set to
+``V4L2_CTRL_WHICH_REQUEST_VAL`` during a call to
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then it will return the
+values of the controls at the time of request completion.
+If the request is not yet completed, then this will result in an
+``EACCES`` error.
+
+The driver will only set/get these controls if all control values are
+correct. This prevents the situation where only some of the controls
+were set/get. Only low-level errors (e. g. a failed i2c command) can
+still cause this situation.

+	the controls can belong to any control class. Whether drivers
+	support this can be tested by setting ``ctrl_class`` to 0 and

+	a request. In the latter case the ``request_fd`` field contains the

+	does not support requests, then ``EACCES`` will be returned.
+
+	.. note::
+
+	   When using ``V4L2_CTRL_WHICH_DEF_VAL`` be aware that you can only
+	   get the default value of the control, you cannot set or try it.
+
+	For backwards compatibility you can also use a control class here
+	(see :ref:`ctrl-class`). In that case all controls have to
+	belong to that control class. This usage is deprecated, instead
+	just use ``V4L2_CTRL_WHICH_CUR_VAL``. There are some very old
+	drivers that do not yet support ``V4L2_CTRL_WHICH_CUR_VAL`` and
+	that require a control class here. You can test for such drivers
+	by setting ctrl_class to ``V4L2_CTRL_WHICH_CUR_VAL`` and calling
+	VIDIOC_TRY_EXT_CTRLS with a count of 0. If that fails, then the
+	driver does not support ``V4L2_CTRL_WHICH_CUR_VAL``.
+    * - }
+      -
+    * - __u32
+      - ``count``
+      - The number of controls in the controls array. May also be zero.
+    * - __u32
+      - ``error_idx``
+      - Set by the driver in case of an error. If the error is associated
+	with a particular control, then ``error_idx`` is set to the index
+	of that control. If the error is not related to a specific
+	control, or the validation step failed (see below), then
+	``error_idx`` is set to ``count``. The value is undefined if the
+	ioctl returned 0 (success).
+
+	Before controls are read from/written to hardware a validation
+	step takes place: this checks if all controls in the list are
+	valid controls, if no attempt is made to write to a read-only
+	control or read from a write-only control, and any other up-front
+	checks that can be done without accessing the hardware. The exact
+	validations done during this step are driver dependent since some
+	checks might require hardware access for some devices, thus making
+	it impossible to do those checks up-front. However, drivers should
+	make a best-effort to do as many up-front checks as possible.
+
+	This check is done to avoid leaving the hardware in an
+	inconsistent state due to easy-to-avoid problems. But it leads to
+	another problem: the application needs to know whether an error
+	came from the validation step (meaning that the hardware was not
+	touched) or from an error during the actual reading from/writing
+	to hardware.
+
+	The, in hindsight quite poor, solution for that is to set
+	``error_idx`` to ``count`` if the validation failed. This has the
+	unfortunate side-effect that it is not possible to see which
+	control failed the validation. If the validation was successful
+	and the error happened while accessing the hardware, then
+	``error_idx`` is less than ``count`` and only the controls up to
+	``error_idx-1`` were read or written correctly, and the state of
+	the remaining controls is undefined.
+
+	Since :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` does not access hardware there is
+	also no need to handle the validation step in this special way, so
+	``error_idx`` will just be set to the control that failed the
+	validation step instead of to ``count``. This means that if
+	:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` fails with ``error_idx`` set to ``count``,
+	then you can call :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` to try to discover the
+	actual control that failed the validation step. Unfortunately,
+	there is no ``TRY`` equivalent for :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.

+

+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_framebuffer`.
+
+
+Description
+===========
+
+Applications can use the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl
+to get and set the framebuffer parameters for a
+:ref:`Video Overlay <overlay>` or :ref:`Video Output Overlay <osd>`
+(OSD). The type of overlay is implied by the device type (capture or
+output device) and can be determined with the
+:ref:`VIDIOC_QUERYCAP` ioctl. One ``/dev/videoN``
+device must not support both kinds of overlay.
+
+The V4L2 API distinguishes destructive and non-destructive overlays. A
+destructive overlay copies captured video images into the video memory
+of a graphics card. A non-destructive overlay blends video images into a
+VGA signal or graphics into a video signal. *Video Output Overlays* are
+always non-destructive.
+
+To get the current parameters applications call the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+ioctl with a pointer to a struct :c:type:`v4l2_framebuffer`
+structure. The driver fills all fields of the structure or returns an
+EINVAL error code when overlays are not supported.
+
+To set the parameters for a *Video Output Overlay*, applications must
+initialize the ``flags`` field of a struct
+:c:type:`v4l2_framebuffer`. Since the framebuffer is
+implemented on the TV card all other parameters are determined by the
+driver. When an application calls :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` with a pointer to
+this structure, the driver prepares for the overlay and returns the
+framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` does, or it returns an error
+code.
+
+To set the parameters for a *non-destructive Video Overlay*,
+applications must initialize the ``flags`` field, the ``fmt``
+substructure, and call :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. Again the driver prepares for
+the overlay and returns the framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+does, or it returns an error code.
+
+For a *destructive Video Overlay* applications must additionally provide
+a ``base`` address. Setting up a DMA to a random memory location can
+jeopardize the system security, its stability or even damage the
+hardware, therefore only the superuser can set the parameters for a
+destructive video overlay.

+      - enum :c:type:`v4l2_field`
+      - ``field``
+      - Drivers and applications shall ignore this field. If applicable,

+
+	This field is irrelevant to *non-destructive Video Overlays*.
+
+	For *destructive Video Overlays* both applications and drivers can
+	set this field to request padding bytes at the end of each line.
+	Drivers however may ignore the requested value, returning
+	``width`` times bytes-per-pixel or a larger value required by the
+	hardware. That implies applications can just set this field to
+	zero to get a reasonable default.
+
+	For *Video Output Overlays* the driver must return a valid value.
+
+	Video hardware may access padding bytes, therefore they must
+	reside in accessible memory. Consider for example the case where
+	padding bytes after the last line of an image cross a system page
+	boundary. Capture devices may write padding bytes, the value is
+	undefined. Output devices ignore the contents of padding bytes.
+
+	When the image format is planar the ``bytesperline`` value applies
+	to the first plane and is divided by the same factor as the
+	``width`` field for the other planes. For example the Cb and Cr
+	planes of a YUV 4:2:0 image have half as many padding bytes
+	following each line as the Y plane. To avoid ambiguities drivers
+	must return a ``bytesperline`` value rounded up to a multiple of
+	the scale factor.

+	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) will be used. Only one
+	video capture driver (bttv) supports this flag. The use of this
+	flag for capture devices is deprecated. There is no way to detect
+	which drivers support this flag, so the only reliable method of
+	setting the overlay size is through
+	:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. If this flag is set for a
+	video output device, then the video output overlay window is
+	relative to the top-left corner of the framebuffer and restricted

+      - 0x0008
+      - Use the alpha channel of the framebuffer to clip or blend

+      - Use a global alpha value to blend the framebuffer with video

+	+ video pixel * (255 - alpha)) / 255. The alpha value is
+	determined by the ``global_alpha`` field of struct

+=========

+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_format`.
+
+
+Description
+===========
+
+These ioctls are used to negotiate the format of data (typically image
+format) exchanged between driver and application.
+
+To query the current parameters applications set the ``type`` field of a
+struct :c:type:`v4l2_format` to the respective buffer (stream)
+type. For example video capture devices use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``. When the application calls the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this structure the driver fills
+the respective member of the ``fmt`` union. In case of video capture
+devices that is either the struct
+:c:type:`v4l2_pix_format` ``pix`` or the struct
+:c:type:`v4l2_pix_format_mplane` ``pix_mp``
+member. When the requested buffer type is not supported drivers return
+an ``EINVAL`` error code.
+
+To change the current format parameters applications initialize the
+``type`` field and all fields of the respective ``fmt`` union member.
+For details see the documentation of the various devices types in
+:ref:`devices`. Good practice is to query the current parameters
+first, and to modify only those parameters not suitable for the
+application. When the application calls the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with
+a pointer to a struct :c:type:`v4l2_format` structure the driver
+checks and adjusts the parameters against hardware abilities. Drivers
+should not return an error code unless the ``type`` field is invalid,
+this is a mechanism to fathom device capabilities and to approach
+parameters acceptable for both the application and driver. On success
+the driver may program the hardware, allocate resources and generally
+prepare for data exchange. Finally the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl returns
+the current format parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Very simple,
+inflexible devices may even ignore all input and always return the
+default parameters. However all V4L2 devices exchanging data with the
+application must implement the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl. When the requested buffer type is not supported drivers return an
+EINVAL error code on a :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` attempt. When I/O is already in
+progress or the resource is not available for other reasons drivers
+return the ``EBUSY`` error code.
+
+The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl is equivalent to :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` with one
+exception: it does not change driver state. It can also be called at any
+time, never returning ``EBUSY``. This function is provided to negotiate
+parameters, to learn about hardware limitations, without disabling I/O
+or possibly time consuming hardware preparations. Although strongly
+recommended drivers are not required to implement this ioctl.
+
+The format as returned by :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` must be identical to what
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` returns for the same input or output.

+Description
+===========
+
+To get the current tuner or modulator radio frequency applications set
+the ``tuner`` field of a struct
+:c:type:`v4l2_frequency` to the respective tuner or
+modulator number (only input devices have tuners, only output devices
+have modulators), zero out the ``reserved`` array and call the
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this structure. The
+driver stores the current frequency in the ``frequency`` field.
+
+To change the current tuner or modulator radio frequency applications
+initialize the ``tuner``, ``type`` and ``frequency`` fields, and the
+``reserved`` array of a struct :c:type:`v4l2_frequency`
+and call the :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl with a pointer to this
+structure. When the requested frequency is not possible the driver
+assumes the closest possible value. However :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` is a
+write-only ioctl, it does not return the actual new frequency.

+===========
+
+To query the current video input applications call the

+
+To select a video input applications store the number of the desired
+input in an integer and call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` ioctl with a pointer
+to this integer. Side effects are possible. For example inputs may
+support different video standards, so the driver may implicitly switch
+the current standard. Because of these possible side effects
+applications must select an input before querying or negotiating any
+other parameters.
+
+Information about video inputs is available using the

+
+[to do]
+
+Ronald Bultje elaborates:
+
+APP is some application-specific information. The application can set it
+itself, and it'll be stored in the JPEG-encoded fields (eg; interlacing
+information for in an AVI or so). COM is the same, but it's comments,
+like 'encoded by me' or so.
+
+jpeg_markers describes whether the huffman tables, quantization tables
+and the restart interval information (all JPEG-specific stuff) should be
+stored in the JPEG-encoded fields. These define how the JPEG field is
+encoded. If you omit them, applications assume you've used standard
+encoding. You usually do want to add them.

+Description
+===========
+
+To query the attributes of a modulator applications initialize the

+:c:type:`v4l2_modulator` and call the
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl with a pointer to this structure. Drivers
+fill the rest of the structure or return an ``EINVAL`` error code when the
+index is out of bounds. To enumerate all modulators applications shall
+begin at index zero, incrementing by one until the driver returns
+EINVAL.
+
+Modulators have two writable properties, an audio modulation set and the
+radio frequency. To change the modulated audio subprograms, applications
+initialize the ``index`` and ``txsubchans`` fields and the ``reserved``
+array and call the :ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Drivers may choose a
+different audio modulation if the request cannot be satisfied. However
+this is a write-only ioctl, it does not return the actual audio
+modulation selected.
+
+:ref:`SDR <sdr>` specific modulator types are ``V4L2_TUNER_SDR`` and
+``V4L2_TUNER_RF``. For SDR devices ``txsubchans`` field must be
+initialized to zero. The term 'modulator' means SDR transmitter in this
+context.
+
+To change the radio frequency the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

+Description
+===========
+
+The current video standard determines a nominal number of frames per
+second. If less than this number of frames is to be captured or output,
+applications can request frame skipping or duplicating on the driver
+side. This is especially useful when using the :ref:`read() <func-read>` or
+:ref:`write() <func-write>`, which are not augmented by timestamps or sequence
+counters, and to avoid unnecessary data copying.
+
+Changing the frame interval shall never change the format. Changing the
+format, on the other hand, may change the frame interval.
+
+Further these ioctls can be used to determine the number of buffers used
+internally by a driver in read/write mode. For implications see the
+section discussing the :ref:`read() <func-read>` function.
+
+To get and set the streaming parameters applications call the
+:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take a
+pointer to a struct :c:type:`v4l2_streamparm` which contains a
+union holding separate parameters for input and output devices.

+
+	-  The driver may support fewer pixel formats than motion capture

+
+	-  The driver may capture and arithmetically combine multiple

+	   reduce the noise in the video data.
+
+	-  The driver may capture images in slices like a scanner in order
+	   to handle larger format images than would otherwise be
+	   possible.
+
+	-  An image capture operation may be significantly slower than
+	   motion capture.
+

+
+Description
+===========
+
+The ioctls are used to query and configure selection rectangles.
+
+To query the cropping (composing) rectangle set struct
+:c:type:`v4l2_selection` ``type`` field to the
+respective buffer type. The next step is setting the
+value of struct :c:type:`v4l2_selection` ``target``
+field to ``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer
+to table :ref:`v4l2-selections-common` or :ref:`selection-api` for
+additional targets. The ``flags`` and ``reserved`` fields of struct
+:c:type:`v4l2_selection` are ignored and they must be
+filled with zeros. The driver fills the rest of the structure or returns
+EINVAL error code if incorrect buffer type or target was used. If
+cropping (composing) is not supported then the active rectangle is not
+mutable and it is always equal to the bounds rectangle. Finally, the
+struct :c:type:`v4l2_rect` ``r`` rectangle is filled with
+the current cropping (composing) coordinates. The coordinates are
+expressed in driver-dependent units. The only exception are rectangles
+for images in raw formats, whose coordinates are always expressed in
+pixels.
+
+To change the cropping (composing) rectangle set the struct
+:c:type:`v4l2_selection` ``type`` field to the
+respective buffer type. The next step is setting the
+value of struct :c:type:`v4l2_selection` ``target`` to
+``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer to table
+:ref:`v4l2-selections-common` or :ref:`selection-api` for additional
+targets. The struct :c:type:`v4l2_rect` ``r`` rectangle need
+to be set to the desired active area. Field struct
+:c:type:`v4l2_selection` ``reserved`` is ignored and
+must be filled with zeros. The driver may adjust coordinates of the
+requested rectangle. An application may introduce constraints to control
+rounding behaviour. The struct :c:type:`v4l2_selection`
+``flags`` field must be set to one of the following:
+
+-  ``0`` - The driver can adjust the rectangle size freely and shall
+   choose a crop/compose rectangle as close as possible to the requested
+   one.
+
+-  ``V4L2_SEL_FLAG_GE`` - The driver is not allowed to shrink the
+   rectangle. The original rectangle must lay inside the adjusted one.
+
+-  ``V4L2_SEL_FLAG_LE`` - The driver is not allowed to enlarge the
+   rectangle. The adjusted rectangle must lay inside the original one.
+
+-  ``V4L2_SEL_FLAG_GE | V4L2_SEL_FLAG_LE`` - The driver must choose the
+   size exactly the same as in the requested rectangle.
+
+Please refer to :ref:`sel-const-adjust`.
+
+The driver may have to adjusts the requested dimensions against hardware
+limits and other parts as the pipeline, i.e. the bounds given by the
+capture/output window or TV display. The closest possible values of
+horizontal and vertical offset and sizes are chosen according to
+following priority:
+
+1. Satisfy constraints from struct
+   :c:type:`v4l2_selection` ``flags``.
+
+2. Adjust width, height, left, and top to hardware limits and
+   alignments.
+
+3. Keep center of adjusted rectangle as close as possible to the
+   original one.
+
+4. Keep width and height as close as possible to original ones.
+
+5. Keep horizontal and vertical offset as close as possible to original
+   ones.
+
+On success the struct :c:type:`v4l2_rect` ``r`` field
+contains the adjusted rectangle. When the parameters are unsuitable the
+application may modify the cropping (composing) or image parameters and
+repeat the cycle until satisfactory parameters have been negotiated. If
+constraints flags have to be violated at then ``ERANGE`` is returned. The
+error indicates that *there exist no rectangle* that satisfies the
+constraints.

+===========
+
+To query and select the current video standard applications use the

+can return a single flag or a set of flags as in struct
+:c:type:`v4l2_standard` field ``id``. The flags must be
+unambiguous such that they appear in only one enumerated
+struct :c:type:`v4l2_standard` structure.
+
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` accepts one or more flags, being a write-only ioctl it
+does not return the actual new standard as :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` does. When
+no flags are given or the current input does not support the requested
+standard the driver returns an ``EINVAL`` error code. When the standard set
+is ambiguous drivers may return ``EINVAL`` or choose any of the requested
+standards. If the current input or output does not support standard

+
+
+Description
+===========
+
+To query the attributes of a tuner applications initialize the ``index``
+field and zero out the ``reserved`` array of a struct
+:c:type:`v4l2_tuner` and call the ``VIDIOC_G_TUNER`` ioctl
+with a pointer to this structure. Drivers fill the rest of the structure
+or return an ``EINVAL`` error code when the index is out of bounds. To
+enumerate all tuners applications shall begin at index zero,
+incrementing by one until the driver returns ``EINVAL``.
+
+Tuners have two writable properties, the audio mode and the radio
+frequency. To change the audio mode, applications initialize the
+``index``, ``audmode`` and ``reserved`` fields and call the
+``VIDIOC_S_TUNER`` ioctl. This will *not* change the current tuner,
+which is determined by the current video input. Drivers may choose a
+different audio mode if the requested mode is invalid or unsupported.
+Since this is a write-only ioctl, it does not return the actually
+selected audio mode.
+
+:ref:`SDR <sdr>` specific tuner types are ``V4L2_TUNER_SDR`` and
+``V4L2_TUNER_RF``. For SDR devices ``audmode`` field must be initialized
+to zero. The term 'tuner' means SDR receiver in this context.
+
+To change the radio frequency the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

+	is set, in units of 1 Hz. If multiple frequency bands are
+	supported, then ``rangelow`` is the lowest frequency of all the
+	frequency bands.
+    * - __u32
+      - ``rangehigh``
+      - :cspan:`1` The highest tunable frequency in units of 62.5 kHz,

+    * -
+      -
+      - ``MONO | STEREO``
+      - receiving mono or stereo audio, the hardware cannot distinguish
+    * -
+      -
+      - ``LANG1 | LANG2``
+      - receiving bilingual audio
+    * -
+      -
+      - ``MONO | STEREO | LANG1 | LANG2``
+      - receiving mono, stereo or bilingual audio
+    * -
+      -
+      - :cspan:`1`
+
+	When the ``V4L2_TUNER_CAP_STEREO``, ``_LANG1``, ``_LANG2`` or
+	``_SAP`` flag is cleared in the ``capability`` field, the
+	corresponding ``V4L2_TUNER_SUB_`` flag must not be set here.
+
+	This field is valid only if this is the tuner of the current video
+	input, or when the structure refers to a radio tuner.
+    * - __u32
+      - ``audmode``
+      - :cspan:`1`
+
+	The selected audio mode, see :ref:`tuner-audmode` for valid
+	values. The audio mode does not affect audio subprogram detection,
+	and like a :ref:`control` it does not automatically
+	change unless the requested mode is invalid or unsupported. See
+	:ref:`tuner-matrix` for possible results when the selected and
+	received audio programs do not match.
+
+	Currently this is the only field of struct

+Description
+===========
+
+As the video/audio devices become more complicated it becomes harder to
+debug problems. When this ioctl is called the driver will output the
+current device status to the kernel log. This is particular useful when
+dealing with problems like no sound, no video and incorrectly tuned
+channels. Also many modern devices autodetect video and audio standards
+and this ioctl will report what the device thinks what the standard is.
+Mismatches may give an indication where the problem is.
+
+This ioctl is optional and not all drivers support it. It was introduced
+in Linux 2.6.15.
+

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_buffer`.
+
+
+Description
+===========
+
+Applications call the ``VIDIOC_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``type`` field of a struct
+:c:type:`v4l2_buffer` to the same buffer type as was
+previously used with struct :c:type:`v4l2_format` ``type``
+and struct :c:type:`v4l2_requestbuffers` ``type``.
+Applications must also set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:c:type:`v4l2_requestbuffers` ``count``) minus
+one. The contents of the struct :c:type:`v4l2_buffer` returned
+by a :ref:`VIDIOC_QUERYBUF` ioctl will do as well.
+When the buffer is intended for output (``type`` is
+``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``,
+or ``V4L2_BUF_TYPE_VBI_OUTPUT``) applications must also initialize the
+``bytesused``, ``field`` and ``timestamp`` fields, see :ref:`buffer`
+for details. Applications must also set ``flags`` to 0. The
+``reserved2`` and ``reserved`` fields must be set to 0. When using the
+:ref:`multi-planar API <planar-apis>`, the ``m.planes`` field must
+contain a userspace pointer to a filled-in array of struct
+:c:type:`v4l2_plane` and the ``length`` field must be set
+to the number of elements in that array.
+
+To enqueue a :ref:`memory mapped <mmap>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_MMAP``. When ``VIDIOC_QBUF`` is called
+with a pointer to this structure the driver sets the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_QUEUED`` flags and clears
+the ``V4L2_BUF_FLAG_DONE`` flag in the ``flags`` field, or it returns an
+``EINVAL`` error code.
+
+To enqueue a :ref:`user pointer <userp>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_USERPTR``, the ``m.userptr`` field to
+the address of the buffer and ``length`` to its size. When the
+multi-planar API is used, ``m.userptr`` and ``length`` members of the
+passed array of struct :c:type:`v4l2_plane` have to be used
+instead. When ``VIDIOC_QBUF`` is called with a pointer to this structure
+the driver sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
+``flags`` field, or it returns an error code. This ioctl locks the
+memory pages of the buffer in physical memory, they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
+:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
+device is closed.
+
+To enqueue a :ref:`DMABUF <dmabuf>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_DMABUF`` and the ``m.fd`` field to a
+file descriptor associated with a DMABUF buffer. When the multi-planar
+API is used the ``m.fd`` fields of the passed array of struct
+:c:type:`v4l2_plane` have to be used instead. When
+``VIDIOC_QBUF`` is called with a pointer to this structure the driver
+sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
+``flags`` field, or it returns an error code. This ioctl locks the
+buffer. Locking a buffer means passing it to a driver for a hardware
+access (usually DMA). If an application accesses (reads/writes) a locked
+buffer then the result is undefined. Buffers remain locked until
+dequeued, until the :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
+:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
+device is closed.
+
+The ``request_fd`` field can be used with the ``VIDIOC_QBUF`` ioctl to specify
+the file descriptor of a :ref:`request <media-request-api>`, if requests are
+in use. Setting it means that the buffer will not be passed to the driver
+until the request itself is queued. Also, the driver will apply any
+settings associated with the request for this buffer. This field will
+be ignored unless the ``V4L2_BUF_FLAG_REQUEST_FD`` flag is set.
+If the device does not support requests, then ``EBADR`` will be returned.
+If requests are supported but an invalid request file descriptor is given,
+then ``EINVAL`` will be returned.
+
+.. caution::
+   It is not allowed to mix queuing requests with queuing buffers directly.
+   ``EBUSY`` will be returned if the first buffer was queued directly and
+   then the application tries to queue a request, or vice versa. After
+   closing the file descriptor, calling
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or calling :ref:`VIDIOC_REQBUFS`
+   the check for this will be reset.
+
+   For :ref:`memory-to-memory devices <mem2mem>` you can specify the
+   ``request_fd`` only for output buffers, not for capture buffers. Attempting
+   to specify this for a capture buffer will result in an ``EBADR`` error.
+
+Applications call the ``VIDIOC_DQBUF`` ioctl to dequeue a filled
+(capturing) or displayed (output) buffer from the driver's outgoing
+queue. They just set the ``type``, ``memory`` and ``reserved`` fields of
+a struct :c:type:`v4l2_buffer` as above, when
+``VIDIOC_DQBUF`` is called with a pointer to this structure the driver
+fills the remaining fields or returns an error code. The driver may also
+set ``V4L2_BUF_FLAG_ERROR`` in the ``flags`` field. It indicates a
+non-critical (recoverable) streaming error. In such case the application
+may continue as normal, but should be aware that data in the dequeued
+buffer might be corrupted. When using the multi-planar API, the planes
+array must be passed in as well.
+
+If the application sets the ``memory`` field to ``V4L2_MEMORY_DMABUF`` to
+dequeue a :ref:`DMABUF <dmabuf>` buffer, the driver fills the ``m.fd`` field
+with a file descriptor numerically the same as the one given to ``VIDIOC_QBUF``
+when the buffer was enqueued. No new file descriptor is created at dequeue time
+and the value is only for the application convenience. When the multi-planar
+API is used the ``m.fd`` fields of the passed array of struct
+:c:type:`v4l2_plane` are filled instead.
+
+By default ``VIDIOC_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <func-open>` function, ``VIDIOC_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The struct :c:type:`v4l2_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+
+
+Description
+===========
+
+The hardware may be able to detect the current DV timings automatically,
+similar to sensing the video standard. To do so, applications call
+:ref:`VIDIOC_QUERY_DV_TIMINGS` with a pointer to a struct
+:c:type:`v4l2_dv_timings`. Once the hardware detects
+the timings, it will fill in the timings structure.
+
+.. note::
+
+   Drivers shall *not* switch timings automatically if new
+   timings are detected. Instead, drivers should send the
+   ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support this) and expect
+   that userspace will take action by calling :ref:`VIDIOC_QUERY_DV_TIMINGS`.
+   The reason is that new timings usually mean different buffer sizes as
+   well, and you cannot change buffer sizes on the fly. In general,
+   applications that receive the Source Change event will have to call
+   :ref:`VIDIOC_QUERY_DV_TIMINGS`, and if the detected timings are valid they
+   will have to stop streaming, set the new timings, allocate new buffers
+   and start streaming again.
+
+If the timings could not be detected because there was no signal, then
+ENOLINK is returned. If a signal was detected, but it was unstable and
+the receiver could not lock to the signal, then ``ENOLCK`` is returned. If
+the receiver could lock to the signal, but the format is unsupported
+(e.g. because the pixelclock is out of range of the hardware
+capabilities), then the driver fills in whatever timings it could find
+and returns ``ERANGE``. In that case the application can call
+:ref:`VIDIOC_DV_TIMINGS_CAP` to compare the
+found timings with the hardware's capabilities in order to give more
+precise feedback to the user.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+ENODATA
+    Digital video timings are not supported for this input or output.
+
+ENOLINK
+    No timings could be detected because no signal was found.
+
+ENOLCK
+    The signal was unstable and the hardware could not lock on to it.
+
+ERANGE
+    Timings were found, but they are out of range of the hardware

+``argp``
+    Pointer to struct :c:type:`v4l2_buffer`.
+
+
+Description
+===========
+
+This ioctl is part of the :ref:`streaming <mmap>` I/O method. It can
+be used to query the status of a buffer at any time after buffers have
+been allocated with the :ref:`VIDIOC_REQBUFS` ioctl.
+
+Applications set the ``type`` field of a struct
+:c:type:`v4l2_buffer` to the same buffer type as was
+previously used with struct :c:type:`v4l2_format` ``type``
+and struct :c:type:`v4l2_requestbuffers` ``type``,
+and the ``index`` field. Valid index numbers range from zero to the
+number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:c:type:`v4l2_requestbuffers` ``count``) minus
+one. The ``reserved`` and ``reserved2`` fields must be set to 0. When
+using the :ref:`multi-planar API <planar-apis>`, the ``m.planes``
+field must contain a userspace pointer to an array of struct
+:c:type:`v4l2_plane` and the ``length`` field has to be set
+to the number of elements in that array. After calling
+:ref:`VIDIOC_QUERYBUF` with a pointer to this structure drivers return an
+error code or fill the rest of the structure.
+
+In the ``flags`` field the ``V4L2_BUF_FLAG_MAPPED``,
+``V4L2_BUF_FLAG_PREPARED``, ``V4L2_BUF_FLAG_QUEUED`` and
+``V4L2_BUF_FLAG_DONE`` flags will be valid. The ``memory`` field will be
+set to the current I/O method. For the single-planar API, the
+``m.offset`` contains the offset of the buffer from the start of the
+device memory, the ``length`` field its size. For the multi-planar API,
+fields ``m.mem_offset`` and ``length`` in the ``m.planes`` array
+elements will be used instead and the ``length`` field of struct
+:c:type:`v4l2_buffer` is set to the number of filled-in
+array elements. The driver may or may not set the remaining fields and
+flags, they are meaningless in this context.
+
+The struct :c:type:`v4l2_buffer` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    The buffer ``type`` is not supported, or the ``index`` is out of
+    bounds.

+
+
+Description
+===========
+
+All V4L2 devices support the ``VIDIOC_QUERYCAP`` ioctl. It is used to
+identify kernel devices compatible with this specification and to obtain
+information about driver and hardware capabilities. The ioctl takes a
+pointer to a struct :c:type:`v4l2_capability` which is
+filled by the driver. When the driver is not compatible with this
+specification the ioctl returns an ``EINVAL`` error code.

+
+    * - __u8
+      - ``driver``\ [16]
+      - Name of the driver, a unique NUL-terminated ASCII string. For
+	example: "bttv". Driver specific applications can use this
+	information to verify the driver identity. It is also useful to
+	work around known bugs, or to identify drivers in error reports.
+
+	Storing strings in fixed sized arrays is bad practice but
+	unavoidable here. Drivers and applications should take precautions
+	to never read or write beyond the end of the array and to make
+	sure the strings are properly NUL-terminated.
+    * - __u8
+      - ``card``\ [32]
+      - Name of the device, a NUL-terminated UTF-8 string. For example:
+	"Yoyodyne TV/FM". One driver may support different brands or
+	models of video hardware. This information is intended for users,
+	for example in a menu of available devices. Since multiple TV
+	cards of the same brand may be installed which are supported by
+	the same driver, this name should be combined with the character
+	device file name (e. g. ``/dev/video2``) or the ``bus_info``
+	string to avoid ambiguities.
+    * - __u8
+      - ``bus_info``\ [32]
+      - Location of the device in the system, a NUL-terminated ASCII
+	string. For example: "PCI:0000:05:06.0". This information is
+	intended for users, to distinguish multiple identical devices. If
+	no such information is available the field must simply count the
+	devices controlled by the driver ("platform:vivi-000"). The
+	bus_info must start with "PCI:" for PCI boards, "PCIe:" for PCI
+	Express boards, "usb-" for USB devices, "I2C:" for i2c devices,
+	"ISA:" for ISA devices, "parport" for parallel port devices and
+	"platform:" for platform devices.
+    * - __u32
+      - ``version``
+      - Version number of the driver.
+
+	Starting with kernel 3.1, the version reported is provided by the
+	V4L2 subsystem following the kernel numbering scheme. However, it
+	may not always return the same version as the kernel if, for
+	example, a stable or distribution-modified kernel uses the V4L2
+	stack from a newer kernel.
+
+	The version number is formatted using the ``KERNEL_VERSION()``
+	macro. For example if the media stack corresponds to the V4L2
+	version shipped with Kernel 4.14, it would be equivalent to:
+    * - :cspan:`2`
+
+	``#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))``
+
+	``__u32 version = KERNEL_VERSION(4, 14, 0);``
+
+	``printf ("Version: %u.%u.%u\\n",``
+
+	``(version >> 16) & 0xFF, (version >> 8) & 0xFF, version & 0xFF);``
+    * - __u32
+      - ``capabilities``
+      - Available capabilities of the physical device as a whole, see
+	:ref:`device-capabilities`. The same physical device can export
+	multiple devices in /dev (e.g. /dev/videoX, /dev/vbiY and
+	/dev/radioZ). The ``capabilities`` field should contain a union of
+	all capabilities available around the several V4L2 devices
+	exported to userspace. For all those devices the ``capabilities``
+	field returns the same set of capabilities. This allows
+	applications to open just one of the devices (typically the video
+	device) and discover whether video, vbi and/or radio are also
+	supported.
+    * - __u32
+      - ``device_caps``
+      - Device capabilities of the opened device, see
+	:ref:`device-capabilities`. Should contain the available
+	capabilities of that specific device node. So, for example,
+	``device_caps`` of a radio device will only contain radio related
+	capabilities and no video or vbi capabilities. This field is only
+	set if the ``capabilities`` field contains the
+	``V4L2_CAP_DEVICE_CAPS`` capability. Only the ``capabilities``
+	field can have the ``V4L2_CAP_DEVICE_CAPS`` capability,
+	``device_caps`` will never set ``V4L2_CAP_DEVICE_CAPS``.
+    * - __u32
+      - ``reserved``\ [3]
+      - Reserved for future extensions. Drivers must set this array to
+	zero.

+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_queryctrl`, :c:type:`v4l2_query_ext_ctrl`
+    or :c:type:`v4l2_querymenu` (depending on the ioctl).
+
+
+Description
+===========
+
+To query the attributes of a control applications set the ``id`` field
+of a struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` and call the
+``VIDIOC_QUERYCTRL`` ioctl with a pointer to this structure. The driver
+fills the rest of the structure or returns an ``EINVAL`` error code when the
+``id`` is invalid.
+
+It is possible to enumerate controls by calling ``VIDIOC_QUERYCTRL``
+with successive ``id`` values starting from ``V4L2_CID_BASE`` up to and
+exclusive ``V4L2_CID_LASTP1``. Drivers may return ``EINVAL`` if a control in
+this range is not supported. Further applications can enumerate private
+controls, which are not defined in this specification, by starting at
+``V4L2_CID_PRIVATE_BASE`` and incrementing ``id`` until the driver
+returns ``EINVAL``.
+
+In both cases, when the driver sets the ``V4L2_CTRL_FLAG_DISABLED`` flag
+in the ``flags`` field this control is permanently disabled and should
+be ignored by the application. [#f1]_
+
+When the application ORs ``id`` with ``V4L2_CTRL_FLAG_NEXT_CTRL`` the
+driver returns the next supported non-compound control, or ``EINVAL`` if
+there is none. In addition, the ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` flag
+can be specified to enumerate all compound controls (i.e. controls with
+type ≥ ``V4L2_CTRL_COMPOUND_TYPES`` and/or array control, in other words
+controls that contain more than one value). Specify both
+``V4L2_CTRL_FLAG_NEXT_CTRL`` and ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` in
+order to enumerate all controls, compound or not. Drivers which do not
+support these flags yet always return ``EINVAL``.
+
+The ``VIDIOC_QUERY_EXT_CTRL`` ioctl was introduced in order to better
+support controls that can use compound types, and to expose additional
+control information that cannot be returned in struct
+:ref:`v4l2_queryctrl <v4l2-queryctrl>` since that structure is full.
+
+``VIDIOC_QUERY_EXT_CTRL`` is used in the same way as
+``VIDIOC_QUERYCTRL``, except that the ``reserved`` array must be zeroed
+as well.
+
+Additional information is required for menu controls: the names of the
+menu items. To query them applications set the ``id`` and ``index``
+fields of struct :ref:`v4l2_querymenu <v4l2-querymenu>` and call the
+``VIDIOC_QUERYMENU`` ioctl with a pointer to this structure. The driver
+fills the rest of the structure or returns an ``EINVAL`` error code when the
+``id`` or ``index`` is invalid. Menu items are enumerated by calling
+``VIDIOC_QUERYMENU`` with successive ``index`` values from struct
+:ref:`v4l2_queryctrl <v4l2-queryctrl>` ``minimum`` to ``maximum``,
+inclusive.
+
+.. note::
+
+   It is possible for ``VIDIOC_QUERYMENU`` to return
+   an ``EINVAL`` error code for some indices between ``minimum`` and
+   ``maximum``. In that case that particular menu item is not supported by
+   this driver. Also note that the ``minimum`` value is not necessarily 0.
+
+See also the examples in :ref:`control`.

+      - This control has a pointer type, so its value has to be accessed
+	using one of the pointer fields of struct

+Description
+===========
+
+The hardware may be able to detect the current video standard

+stores here a set of candidates, this can be a single flag or a set of
+supported standards if for example the hardware can only distinguish
+between 50 and 60 Hz systems. If no signal was detected, then the driver
+will return V4L2_STD_UNKNOWN. When detection is not possible or fails,
+the set must contain all standards supported by the current video input
+or output.
+
+.. note::
+
+   Drivers shall *not* switch the video standard
+   automatically if a new video standard is detected. Instead, drivers
+   should send the ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support
+   this) and expect that userspace will take action by calling
+   :ref:`VIDIOC_QUERYSTD`. The reason is that a new video standard can mean
+   different buffer sizes as well, and you cannot change buffer sizes on
+   the fly. In general, applications that receive the Source Change event
+   will have to call :ref:`VIDIOC_QUERYSTD`, and if the detected video
+   standard is valid they will have to stop streaming, set the new
+   standard, allocate new buffers and start streaming again.

+VIDIOC_REQBUFS - Initiate Memory Mapping, User Pointer I/O or DMA buffer I/O
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_REQBUFS, struct v4l2_requestbuffers *argp )
+    :name: VIDIOC_REQBUFS
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_requestbuffers`.
+
+Description
+===========
+
+This ioctl is used to initiate :ref:`memory mapped <mmap>`,
+:ref:`user pointer <userp>` or :ref:`DMABUF <dmabuf>` based I/O.
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+struct :c:type:`v4l2_requestbuffers` structure. They set the ``type``
+field to the respective stream or buffer type, the ``count`` field to
+the desired number of buffers, ``memory`` must be set to the requested
+I/O method and the ``reserved`` array must be zeroed. When the ioctl is
+called with a pointer to this structure the driver will attempt to
+allocate the requested number of buffers and it stores the actual number
+allocated in the ``count`` field. It can be smaller than the number
+requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. For example video output requires at least two
+buffers, one displayed and one filled by the application.
+
+When the I/O method is not supported the ioctl returns an ``EINVAL`` error
+code.
+
+Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of
+buffers. Note that if any buffers are still mapped or exported via DMABUF,
+then :ref:`VIDIOC_REQBUFS` can only succeed if the
+``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` capability is set. Otherwise
+:ref:`VIDIOC_REQBUFS` will return the ``EBUSY`` error code.
+If ``V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS`` is set, then these buffers are
+orphaned and will be freed when they are unmapped or when the exported DMABUF
+fds are closed. A ``count`` value of zero frees or orphans all buffers, after
+aborting or finishing any DMA in progress, an implicit
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`.

+Description
+===========
+
+Start a hardware frequency seek from the current frequency. To do this
+applications initialize the ``tuner``, ``type``, ``seek_upward``,
+``wrap_around``, ``spacing``, ``rangelow`` and ``rangehigh`` fields, and
+zero out the ``reserved`` array of a struct
+:c:type:`v4l2_hw_freq_seek` and call the
+``VIDIOC_S_HW_FREQ_SEEK`` ioctl with a pointer to this structure.
+
+The ``rangelow`` and ``rangehigh`` fields can be set to a non-zero value
+to tell the driver to search a specific band. If the struct
+:c:type:`v4l2_tuner` ``capability`` field has the
+``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag set, these values must fall
+within one of the bands returned by
+:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
+``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag is not set, then these values
+must exactly match those of one of the bands returned by
+:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
+current frequency of the tuner does not fall within the selected band it
+will be clamped to fit in the band before the seek is started.
+
+If an error is returned, then the original frequency will be restored.
+
+This ioctl is supported if the ``V4L2_CAP_HW_FREQ_SEEK`` capability is
+set.
+
+If this ioctl is called from a non-blocking filehandle, then ``EAGAIN``

+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to an integer.
+
+Description
+===========
+
+The ``VIDIOC_STREAMON`` and ``VIDIOC_STREAMOFF`` ioctl start and stop
+the capture or output process during streaming
+(:ref:`memory mapping <mmap>`, :ref:`user pointer <userp>` or
+:ref:`DMABUF <dmabuf>`) I/O.
+
+Capture hardware is disabled and no input buffers are filled (if there
+are any empty buffers in the incoming queue) until ``VIDIOC_STREAMON``
+has been called. Output hardware is disabled and no video signal is
+produced until ``VIDIOC_STREAMON`` has been called. The ioctl will
+succeed when at least one output buffer is in the incoming queue.
+
+Memory-to-memory devices will not start until ``VIDIOC_STREAMON`` has
+been called for both the capture and output stream types.
+
+If ``VIDIOC_STREAMON`` fails then any already queued buffers will remain
+queued.
+
+The ``VIDIOC_STREAMOFF`` ioctl, apart of aborting or finishing any DMA
+in progress, unlocks any user pointer buffers locked in physical memory,
+and it removes all buffers from the incoming and outgoing queues. That
+means all images captured but not dequeued yet will be lost, likewise
+all images enqueued for output but not transmitted yet. I/O returns to
+the same state as after calling
+:ref:`VIDIOC_REQBUFS` and can be restarted
+accordingly.
+
+If buffers have been queued with :ref:`VIDIOC_QBUF` and
+``VIDIOC_STREAMOFF`` is called without ever having called
+``VIDIOC_STREAMON``, then those queued buffers will also be removed from
+the incoming queue and all are returned to the same state as after
+calling :ref:`VIDIOC_REQBUFS` and can be restarted
+accordingly.
+
+Both ioctls take a pointer to an integer, the desired buffer or stream
+type. This is the same as struct
+:c:type:`v4l2_requestbuffers` ``type``.
+
+If ``VIDIOC_STREAMON`` is called when streaming is already in progress,
+or if ``VIDIOC_STREAMOFF`` is called when streaming is already stopped,
+then 0 is returned. Nothing happens in the case of ``VIDIOC_STREAMON``,
+but ``VIDIOC_STREAMOFF`` will return queued buffers to their starting
+state as mentioned above.
+
+.. note::
+
+   Applications can be preempted for unknown periods right before
+   or after the ``VIDIOC_STREAMON`` or ``VIDIOC_STREAMOFF`` calls, there is
+   no notion of starting or stopping "now". Buffer timestamps can be used
+   to synchronize with other events.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+

+    The buffer ``type`` is not supported, or no buffers have been
+    allocated (memory mapping) or enqueued (output) yet.

+VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL - Enumerate frame intervals
+
+
+Synopsis
+========
+
+.. c:function:: int ioctl( int fd, VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL, struct v4l2_subdev_frame_interval_enum * argp )
+    :name: VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_subdev_frame_interval_enum`.
+
+
+Description
+===========
+
+This ioctl lets applications enumerate available frame intervals on a
+given sub-device pad. Frame intervals only makes sense for sub-devices
+that can control the frame period on their own. This includes, for
+instance, image sensors and TV tuners.
+
+For the common use case of image sensors, the frame intervals available
+on the sub-device output pad depend on the frame format and size on the
+same pad. Applications must thus specify the desired format and size
+when enumerating frame intervals.
+
+To enumerate frame intervals applications initialize the ``index``,
+``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
+:c:type:`v4l2_subdev_frame_interval_enum`
+and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
+to this structure. Drivers fill the rest of the structure or return an
+EINVAL error code if one of the input fields is invalid. All frame
+intervals are enumerable by beginning at index zero and incrementing by
+one until ``EINVAL`` is returned.
+
+Available frame intervals may depend on the current 'try' formats at
+other pads of the sub-device, as well as on the current active links.
+See :ref:`VIDIOC_SUBDEV_G_FMT` for more
+information about the try formats.
+
+Sub-devices that support the frame interval enumeration ioctl should
+implemented it on a single pad only. Its behaviour when supported on
+multiple pads of the same sub-device is not defined.

+
+
+Description
+===========
+
+This ioctl allows applications to enumerate all frame sizes supported by
+a sub-device on the given pad for the given media bus format. Supported
+formats can be retrieved with the
+:ref:`VIDIOC_SUBDEV_ENUM_MBUS_CODE`
+ioctl.
+
+To enumerate frame sizes applications initialize the ``pad``, ``which``
+, ``code`` and ``index`` fields of the struct
+:c:type:`v4l2_subdev_mbus_code_enum` and
+call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_SIZE` ioctl with a pointer to the
+structure. Drivers fill the minimum and maximum frame sizes or return an
+EINVAL error code if one of the input parameters is invalid.
+
+Sub-devices that only support discrete frame sizes (such as most
+sensors) will return one or more frame sizes with identical minimum and
+maximum values.
+
+Not all possible sizes in given [minimum, maximum] ranges need to be
+supported. For instance, a scaler that uses a fixed-point scaling ratio
+might not be able to produce every frame size between the minimum and
+maximum values. Applications must use the
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl to try the
+sub-device for an exact supported frame size.
+
+Available frame sizes may depend on the current 'try' formats at other
+pads of the sub-device, as well as on the current active links and the
+current values of V4L2 controls. See
+:ref:`VIDIOC_SUBDEV_G_FMT` for more
+information about try formats.

+.. note::
+
+    This is an :ref:`obsolete` interface and may be removed
+    in the future. It is superseded by
+    :ref:`the selection API <VIDIOC_SUBDEV_G_SELECTION>`.
+
+To retrieve the current crop rectangle applications set the ``pad``
+field of a struct :c:type:`v4l2_subdev_crop` to the

+to ``V4L2_SUBDEV_FORMAT_ACTIVE``. They then call the

+code if the input arguments are invalid, or if cropping is not supported

+
+To change the current crop rectangle applications set both the ``pad``
+and ``which`` fields and all members of the ``rect`` field. They then
+call the ``VIDIOC_SUBDEV_S_CROP`` ioctl with a pointer to this
+structure. The driver verifies the requested crop rectangle, adjusts it

+
+Applications can query the device capabilities by setting the ``which``

+applied to the device by the driver, but are mangled exactly as active
+crop rectangles and stored in the sub-device file handle. Two
+applications querying the same sub-device would thus not interact with
+each other.
+
+Drivers must not return an error solely because the requested crop
+rectangle doesn't match the device capabilities. They must instead
+modify the rectangle to match what the hardware can provide. The
+modified format should be as close as possible to the original request.

+
+
+Description
+===========
+
+These ioctls are used to negotiate the frame format at specific subdev
+pads in the image pipeline.
+
+To retrieve the current format applications set the ``pad`` field of a
+struct :c:type:`v4l2_subdev_format` to the desired
+pad number as reported by the media API and the ``which`` field to
+``V4L2_SUBDEV_FORMAT_ACTIVE``. When they call the
+``VIDIOC_SUBDEV_G_FMT`` ioctl with a pointer to this structure the
+driver fills the members of the ``format`` field.
+
+To change the current format applications set both the ``pad`` and
+``which`` fields and all members of the ``format`` field. When they call
+the ``VIDIOC_SUBDEV_S_FMT`` ioctl with a pointer to this structure the
+driver verifies the requested format, adjusts it based on the hardware
+capabilities and configures the device. Upon return the struct
+:c:type:`v4l2_subdev_format` contains the current
+format as would be returned by a ``VIDIOC_SUBDEV_G_FMT`` call.
+
+Applications can query the device capabilities by setting the ``which``
+to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' formats are not applied
+to the device by the driver, but are changed exactly as active formats
+and stored in the sub-device file handle. Two applications querying the
+same sub-device would thus not interact with each other.
+
+For instance, to try a format at the output pad of a sub-device,
+applications would first set the try format at the sub-device input with
+the ``VIDIOC_SUBDEV_S_FMT`` ioctl. They would then either retrieve the
+default format at the output pad with the ``VIDIOC_SUBDEV_G_FMT`` ioctl,
+or set the desired output pad format with the ``VIDIOC_SUBDEV_S_FMT``
+ioctl and check the returned value.
+
+Try formats do not depend on active formats, but can depend on the
+current links configuration or sub-device controls value. For instance,
+a low-pass noise filter might crop pixels at the frame boundaries,
+modifying its output frame size.
+
+Drivers must not return an error solely because the requested format
+doesn't match the device capabilities. They must instead modify the
+format to match what the hardware can provide. The modified format
+should be as close as possible to the original request.

+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``argp``
+    Pointer to struct :c:type:`v4l2_subdev_frame_interval`.
+
+
+Description
+===========
+
+These ioctls are used to get and set the frame interval at specific
+subdev pads in the image pipeline. The frame interval only makes sense
+for sub-devices that can control the frame period on their own. This
+includes, for instance, image sensors and TV tuners. Sub-devices that
+don't support frame intervals must not implement these ioctls.
+
+To retrieve the current frame interval applications set the ``pad``
+field of a struct
+:c:type:`v4l2_subdev_frame_interval` to
+the desired pad number as reported by the media controller API. When
+they call the ``VIDIOC_SUBDEV_G_FRAME_INTERVAL`` ioctl with a pointer to
+this structure the driver fills the members of the ``interval`` field.
+
+To change the current frame interval applications set both the ``pad``
+field and all members of the ``interval`` field. When they call the
+``VIDIOC_SUBDEV_S_FRAME_INTERVAL`` ioctl with a pointer to this
+structure the driver verifies the requested interval, adjusts it based
+on the hardware capabilities and configures the device. Upon return the
+struct
+:c:type:`v4l2_subdev_frame_interval`
+contains the current frame interval as would be returned by a
+``VIDIOC_SUBDEV_G_FRAME_INTERVAL`` call.
+
+Drivers must not return an error solely because the requested interval
+doesn't match the device capabilities. They must instead modify the
+interval to match what the hardware can provide. The modified interval
+should be as close as possible to the original request.
+
+Changing the frame interval shall never change the format. Changing the
+format, on the other hand, may change the frame interval.
+
+Sub-devices that support the frame interval ioctls should implement them
+on a single pad only. Their behaviour when supported on multiple pads of
+the same sub-device is not defined.

+    Pointer to struct :c:type:`v4l2_subdev_selection`.
+
+
+Description
+===========
+
+The selections are used to configure various image processing
+functionality performed by the subdevs which affect the image size. This
+currently includes cropping, scaling and composition.
+
+The selection API replaces
+:ref:`the old subdev crop API <VIDIOC_SUBDEV_G_CROP>`. All the
+function of the crop API, and more, are supported by the selections API.
+
+See :ref:`subdev` for more information on how each selection target
+affects the image processing pipeline inside the subdevice.
+
+
+Types of selection targets
+--------------------------
+
+There are two types of selection targets: actual and bounds. The actual
+targets are the targets which configure the hardware. The BOUNDS target
+will return a rectangle that contain all possible actual rectangles.
+
+
+Discovering supported features
+------------------------------
+
+To discover which targets are supported, the user can perform
+``VIDIOC_SUBDEV_G_SELECTION`` on them. Any unsupported target will
+return ``EINVAL``.
+
+Selection targets and flags are documented in
+:ref:`v4l2-selections-common`.

+YUV Formats
+***********
+
+YUV is the format native to TV broadcast and composite video signals. It
+separates the brightness information (Y) from the color information (U
+and V or Cb and Cr). The color information consists of red and blue
+*color difference* signals, this way the green component can be
+reconstructed by subtracting from the brightness component. See
+:ref:`colorspaces` for conversion examples. YUV was chosen because
+early television would only transmit brightness information. To add
+color in a way compatible with existing receivers a new signal carrier
+was added to transmit the color difference signals. Secondary in the YUV
+format the U and V components usually have lower resolution than the Y
+component. This is an analog video compression technique taking
+advantage of a property of the human visual system, being more sensitive
+to brightness information.
