[MPlayer-dev-eng] [PATCH] libdav1d support

[Andrew Randrianasulu]

Hello.

I tried to add libdav1d support into mplayer/ffmpeg.
It works as in - shows picture from webm/mp4 and allow me to seek around. 
But my check for header (like in ALSA check) may be not good (ffmpeg only 
supports libdav1d >=0.2.1)

MPlayer svn  38140
ffmpeg git commit 1eb54323c82ff6eff18553fd3f2788a695bdf812

MPlayer emit this warning, I assume for removing it whole interface between 
mplayer and  libavcodec's decoders must be upgraded?
