Please remember that you are assuming that the 
respective FFmpeg decoder has no bugs!

You could always output rawvideo (from different 
programs) and compare with diff (or md5).

I did not realize that framemd5 can be used to 
check for hardware bugs / calculation errors, 
this is of course useful (but you should be 
aware of what you test).
