What does "fails" mean? The player stops? Which player? The video goes black 
but playing continues? Please be specific.

a) as long as the status messages continue, it doesn't look like anything 
has stopped.

b) the complete command line is missing, so we don't know what's actually 
being done.

You may want to try multiple players to see what's in the file and look at 
it with ffprobe and mediainfo. Also try encoding into a different format 
which will force ffmpeg to demux/decode the frames; that might turn up 
something.


As per the list FAQ, always include the complete command line and DO NOT 
top-post.

z!
