 (Sample from videolan ticket 8618)
 A vlc user pointed to a broken avi sample that transcodes fine with ffmpeg
 (the output file plays in-sync) but shows A/V desync when played with
 ffplay.
 Workaround is to seek over the broken parts.
 To reproduce, play the sample for 50 seconds to see the problem, seek
 instead three times 10 seconds forward to see the same scene play in-sync.
 If the huge sample is cut, seeking does not allow anymore to fix the
 desync.
