mainline kernel hardware acceleration

[xmixahlx]

i think mpv hwaccel is currently broken due to v4l2request not being detected. (ffmpeg -decoders | grep v4l)

for quick test monitor top and use: "ffmpeg -re --hwaccel drm -i inputfile -f null -"

for hwaccel playback use kodi-git. see my other thread. i am also using jellyfin-kodi. works great playing files from my htpc/server.

5.7 is released so i will update patches soon.
