[FFmpeg-user] r600 mplayer -vc ffmpeg12vdpau regression since vdpau: Add MPEG-1/2 decoding via hwaccel infrastructure

[Andy Furniss]

Maybe this should go to the mplayer list, but it is an ffmpeg commit 
that causes it.

I have a regression using radeon r600 vdpau decode with mplayer -vc 
ffmpeg12vdpau.

It's possible it's just exposing some r600 mpeg2 decode issues - which 
has never worked accurately, but then it may be an ffmpeg bug - I don't 
have any nvidia h/w to test with.

Here are before and after the above commit showing extra artifacts.
