| * - ``V4L2_SEL_FLAG_GE`` |
| - (1 << 0) |
| - Suggest the driver it should choose greater or equal rectangle (in |
| size) than was requested. Albeit the driver may choose a lesser |
| size, it will only do so due to hardware limitations. Without this |
| flag (and ``V4L2_SEL_FLAG_LE``) the behaviour is to choose the |
| closest possible rectangle. |
| - Yes |
| - Yes |
| * - ``V4L2_SEL_FLAG_LE`` |
| - (1 << 1) |

| size, it will only do so due to hardware limitations. |
| - Yes |
| - Yes |
| * - ``V4L2_SEL_FLAG_KEEP_CONFIG`` |
| - (1 << 2) |
| - The configuration must not be propagated to any further processing |
| steps. If this flag is not given, the configuration is propagated |
| inside the subdevice to all further processing steps. |
| - No |
