[MPlayer-dev-eng] ffmpeg av1 decoding with dav1d

[sylvain.bertrand at gmail.com]

Hi,

I made a build of a recent snapshot of mplayer with a git ffmpeg where I did
enable av1 decoding using dav1d.

It seems mplayer misses codecs.conf entries for av1. I did copy grossely the libvpxvp9 codecs.conf section:

videocodec fflibdav1d
  info "FFmpeg libdav1d"
  status working
; mkv
  format 0x31307661
; mp4
  format 0x31305641
  driver ffmpeg
  dll libdav1d
  out YV12,420P10,420P12
  out 422P,422P10,422P12
  out 440P,440P10,440P12
  out 444P,444P10,444P12
  out GBR10P,GBR12P,GBR24P

Then I could read youtube av1 encoded test videos from https://www.youtube.com/playlist?list=PLyqf6gJt7KuHBmeVzZteZUlNUQAVLwrZS
downloaded with youtube-dl (which uses an av1/dav1d enabled ffmpeg build for mkv remuxing)

Could an experienced dev with commit access add proper av1 entries in the built-in codecs.conf of mplayer?

thx and best regards,
