David <[email protected]> added the comment:
I uploaded my sample to the upload.ffmpeg.org ftp server, under fpe-ffmpeg/.
I also have a patch that checks ist->st->codec->time_base.den so it doesn't
divide by zero.
(patcheck says "x==0 / x!=0 can be simplified to !x / x" but I followed in the
same style as the code that was there.)
