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.
