Re: [FFmpeg-user] abort and missing SIGABRT handling

But if the abort() are reached, that's a bug, either in FFmpeg or in  
the

program that uses its libraries. Catching the signal is likely to make
things worse. Remember that these asserts may be the final barrier
against an exploitable bug.


   And in case of a catastophic event, with abort() you can
   have a coredump for postmortem analysing...

I've found other people with this problem online but found no workable
solutions. If you have any ideas I'd be happy to hear them --


  copy img-01.jpg to img-00.jpg and rerun your command ?
