later insertion of rows with minimal diffs.

Multi-planar format structures
|

******************************
|
|
|
|
The struct :c:type:`v4l2_plane_pix_format` structures define size
|
|
and layout for each of the planes in a multi-planar format. The
|
|
struct :c:type:`v4l2_pix_format_mplane` structure contains
|
|
information common to all planes (such as image width and height) and an
|
|
array of struct :c:type:`v4l2_plane_pix_format` structures,
|
|
describing all planes of that format.

- Maximum size in bytes required for image data in this plane.

- Distance in bytes between the leftmost pixels in two adjacent
|

lines. See struct :c:type:`v4l2_pix_format`.
|

|
|
- ``plane_fmt[VIDEO_MAX_PLANES]``
|
|
- An array of structures describing format of each plane this pixel
|

format consists of. The number of valid entries in this array has
|
|
to be put in the ``num_planes`` field.
|
|
* - __u8
|
|
- ``num_planes``
|
