.. _v4l2-selections-common:
Common selection definitions
============================
While the :ref:`V4L2 selection API <selection-api>` and
:ref:`V4L2 subdev selection APIs <v4l2-subdev-selections>` are very
similar, there's one fundamental difference between the two. On
sub-device API, the selection rectangle refers to the media bus format,
and is bound to a sub-device's pad. On the V4L2 interface the selection
rectangles refer to the in-memory pixel format.
This section defines the common definitions of the selection interfaces
on the two APIs.
