[FFmpeg-devel] [PATCH 0/4] Add AVDRMFrameDescriptor.format field

[Jonas Karlman]

Hello,

When a multi-layer AVDRMFrameDescriptor is used to describe a frame the overall
frame format is missing and applications need to deduce the frame DRM_FORMAT_*
based on sw_format or the layers format.

This patchset adds a AVDRMFrameDescriptor.format field to remove any ambiguity
of what frame format a multi-layer descriptor may have.

Kodi has up until now only supported single layer AVDRMFrameDescriptor,
when trying to add support for multi-layer frame descriptors [1],
we did not want to try and deduce the frame format, hence this patchset.

Patch 1 adds a new field, format, to the AVDRMFrameDescriptor struct.
Patch 2-4 adds code to set the new format field.

Regards,
Jonas
