12Common selection definitions
13============================
14
15While the :ref:`V4L2 selection API <selection-api>` and
16:ref:`V4L2 subdev selection APIs <v4l2-subdev-selections>` are very
17similar, there's one fundamental difference between the two. 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.
