   5 Common selection definitions
   6 ============================
   7
   8 While the :ref:`V4L2 selection API <selection-api>` and
   9 :ref:`V4L2 subdev selection APIs <v4l2-subdev-selections>` are very
  10 similar, there's one fundamental difference between the two. On
  11 sub-device API, the selection rectangle refers to the media bus format,
  12 and is bound to a sub-device's pad. On the V4L2 interface the selection
  13 rectangles refer to the in-memory pixel format.

  15 This section defines the common definitions of the selection interfaces
  16 on the two APIs.
