I'm still not sure of the scope that this problem has.

If image corruption always happens with MT+HWAccel, why didn't VLC
change this long ago due to users complaining about that?

I assume that's because it works well enough in most cases?

Also, can the crashes be reproduced with the command line tools
from FFmpeg 2.8?
