Repository for v4l2request hardware video decoding (rockchip, allwinner)
Hello, this quick tutorial is to introduce an experimental Debian and Ubuntu APT repository to install ffmpeg compiled with v4l2request and v4l2drmprime patches developed by Linux kernel, LIbreELEC and Kodi folks to allow hardware video decoding on stateless decoders like those implemented in Rockchip and Allwinner SoCs for h.264, h.265, vp8 and vp9 codecs.
The repository introduces a new ffmpeg package that integrates and substitues the base ffmpeg package and its related packages.
The kernel fix in NickA’s Armbian, allows ffmpeg-v4l2 play 1080p with hardware acceleration, under X11 (openbox wm), with “mpv filename.mp4”
I git-cloned his repo, selected orangepizero3, changed nothing, kept all his repo’s patches, chose bookworm minimal, Linux edge 6.7.12
i installed lightdm and xorg, then jock’s package repo for ffmpeg-v4l2requedt, then installed mpv (official bookworm package).
the 720p and 1080p videos played fine, with 5% cpu
