Comment 5 haihao 2011-11-14 18:17:42 UTC

I can reproduce this issue with -vo gl on some machines as well, so this isn't a VAAPI specific issue.  I will mark this issue as NOTOURBUG.  Please file a new bug about this issue.  If you still experience this issue with libva after fixing the new bug, feel free to reopen this bug.
