On 18sub-device API, the selection rectangle refers to the media bus format, 19and is bound to a sub-device's pad. On the V4L2 interface the selection 20rectangles refer to the in-memory pixel format. 21 22This section defines the common definitions of the selection interfaces 23on the two APIs. 24 25 26.. toctree:: 27 :maxdepth: 1 28 29 v4l2-selection-targets 30 v4l2-selection-flags 31
