It depends of which decoder is used. With ffmpeg from fedora 20
(ffmpeg-2.1.5-1.fc20.x86_64) and its software mpeg4 decoder, the video plays
fine. But using the vdpau decoder causes corruptions starting around 10s. I
think they may be related to s-frames not being handled by the hardware
decoder. I added some details about this in the freedesktop bug where I got the
sample video.
