V4L2 Request API hwaccels for stateless decoders such as Allwinner
cedrus, exporting DRM_PRIME frames, and a V4L2 M2M deinterlace filter
driving mem2mem deinterlacers such as Allwinner's sun8i-di on DRM_PRIME
frames. The hwaccels introduce the v4l2-request and libudev configure
options.
Add the FFMPEG_V4L2_REQUEST option (pulls libdrm and libudev) to the
libffmpeg menu, keep both new configure options explicitly off in the
common block like the other autodetected ones, and re-add the
*_v4l2request hwaccels under manual component selection.
Patches:
120-v4l2-request-01 to -13: carried over from LibreELEC
(packages/multimedia/ffmpeg/patches/v4l2-request/0001-v4l2-request.patch

140-vf-deinterlace-v4l2m2m: carried over from LibreELEC
(packages/multimedia/ffmpeg/patches/vf-deinterlace-v4l2m2m/0001-vf-deinterlace-v4l2m2m.patch
as of LibreELEC commit 9ef6c9c6f7; Jernej Skrabec): adds the
deinterlace_v4l2m2m filter
Headers unchanged, hunks refreshed with quilt; the patched tree is
identical to the one LibreELEC's files produce.
LibreELEC's v4l2-drmprime patch (stateful M2M decoders) is not carried:
it needs a rebase for FFmpeg 9 which LibreELEC has not done either.
The V4L2 Request API series is under review upstream as:
https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20847
The patches here are taken from LibreELEC, though,
as that's the set that Kodi is built and tested against,
incl. some platform specific fixes.
