Bug#765967: [libvdpau1] mpeg 1 video are decoded too bad

[Francesco Muzio]

Package: libvdpau1
Version: 0.8-1
Severity: normal

Dear maintainer,

When I play a video encoded with mpeg1 using VLC (or xine-ui) and VDPAU 
acceleration enabled I see an almost-full green screen instead of the 
video.

other codec like MPEG2 and H264 seem working well

I have tried some mpeg1 videos of different origin and all have the same 
problem.

for example you can expirience the problem when playing this little video
http://www.fileformat.info/format/mpeg/sample/567fd6a0e0da4a8e81bdeb870de3b19c/DELTA.MPG

With a player with hardware acceleration disabled this video is played 
as expected
