Yes. It seems that in some cases av_read_frame reports an error but 
there can be frames to read. Unfortunately I don't remember a test case. 
That was the reason why there was a test on url_ferror() or url_feof() 
in the code. That's also probably the reason why it is in ffplay too.

So maybe it's only the MOV demuxer that have this weird behaviour ? As 
all other kind of files I have seem to work fine...
