[FFmpeg-user] h264 not decoding

[Rens Dijkshoorn]

Hi Bouke

its not that simple, file is recorded by some sort
of flash based camera i'm still waiting on the details
about settings type of camera etc.

And more files are underway so i would like to bring into
our standard workflow.

If i just use video copy to h264 the resulting video is
not playable at all. During conversion i get these kind
of error messages... 

[h264 @ 0x10100c200] st:0 error, non monotone timestamps 100800 >= 99040
[NULL @ 0x101014200] non-existing SPS 2 referenced in buffering periodbits/s    
[h264 @ 0x10100c200] st:0 error, non monotone timestamps 9882000 >= 9882000/s    
[h264 @ 0x10100c200] st:0 error, non monotone timestamps 10011600 >= 10011600
[NULL @ 0x101014200] non-existing SPS 2 referenced in buffering periodkbits/s    
[h264 @ 0x10100c200] st:0 error, non monotone timestamps 50425200 >= 50411200  

sofar no luck

Rens, 
Perhaps copy protection stuff that is messing things up? 
Where did you get the file? 
And if it is a one-off, and you have means to convert it, why not use that 
and just be done with it?
