| * - ``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) | |
| - Suggest the driver it should choose lesser or equal rectangle (in | |
| size) than was requested. Albeit the driver may choose a greater | |
| 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 | |
