Summary of the bug:
I play some h264 video with MPC (LAV filter), VLC, Pot Player (ffmpeg),
and found there are some bad images. then I try ffplay, same problem.
(there are all ffmpeg based as I know)
meanwhile I test Microsoft windows media player, it plays fine. QuickTime
Player has some visible blocks but it looks much better than ffmpeg. And
some other decoders they all play OK.
Can someone please to help to check what's wrong with attached h264 video,
can ffmpeg play these video without visible bad images ?
Following is ffplay log
