| The saa7134 driver |
| ================== |
| |
| Author Gerd Hoffmann |
| |
| |
| This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV |
| boards. |
| |
| |
| Status |
| ------ |
| |
| Almost everything is working. video, sound, tuner, radio, mpeg ts, ... |
| |
| As with bttv, card-specific tweaks are needed. Check CARDLIST for a |
| list of known TV cards and saa7134-cards.c for the drivers card |
| configuration info. |
| |
| |
| Build |
| ----- |
| |
| Once you pick up a Kernel source, you should configure, build, |
| install and boot the new kernel. You'll need at least |
| these config options:: |
| |
| ./scripts/config -e PCI |
| ./scripts/config -e INPUT |
| ./scripts/config -m I2C |
| ./scripts/config -m MEDIA_SUPPORT |
| ./scripts/config -e MEDIA_PCI_SUPPORT |
| ./scripts/config -e MEDIA_ANALOG_TV_SUPPORT |
| ./scripts/config -e MEDIA_DIGITAL_TV_SUPPORT |
| ./scripts/config -e MEDIA_RADIO_SUPPORT |
| ./scripts/config -e RC_CORE |
| ./scripts/config -e MEDIA_SUBDRV_AUTOSELECT |
| ./scripts/config -m VIDEO_SAA7134 |
| ./scripts/config -e SAA7134_ALSA |
| ./scripts/config -e VIDEO_SAA7134_RC |
| ./scripts/config -e VIDEO_SAA7134_DVB |
| ./scripts/config -e VIDEO_SAA7134_GO7007 |
| |
| To build and install, you should run:: |
| |
| make && make modules_install && make install |
| |
| Once the new Kernel is booted, saa7134 driver should be loaded automatically. |
| |
| Depending on the card you might have to pass ``card=<nr>`` as insmod option. |
| If so, please check Documentation/admin-guide/media/saa7134-cardlist.rst |
| for valid choices. |
| |
| Once you have your card type number, you can pass a modules configuration |
| via a file (usually, it is either ``/etc/modules.conf`` or some file at |
| ``/etc/modules-load.d/``, but the actual place depends on your |
| distribution), with this content:: |
| |
| options saa7134 card=13 # Assuming that your card type is #13 |
| |
| |
| Changes / Fixes |
| --------------- |
| |
| Please mail to linux-media AT vger.kernel.org unified diffs against |
| the linux media git tree: |
| |
| https://git.linuxtv.org/media_tree.git/ |
| |
| This is done by committing a patch at a clone of the git tree and |
| submitting the patch using ``git send-email``. Don't forget to |
| describe at the lots what it changes / which problem it fixes / whatever |
| it is good for ... |
| |
| |
| Known Problems |
| -------------- |
| |
| * The tuner for the flyvideos isn't detected automatically and the |
| default might not work for you depending on which version you have. |
| There is a ``tuner=`` insmod option to override the driver's default. |
