Replying to [comment:4 cehoyos]:
> Please provide a sample that allows to reproduce the crash.
No problem. Do I need to follow "Submitting Sample Media" under
http://www.ffmpeg.org/bugreports.html exactly (splitting in 10,000-byte
chunks, converting to RGB/YUV/PCM? etc.), or can I just upload the
appropriately renamed VTS_01_4.VOB?
> Am I correct that the crash does not happen if you either use {{{-vsync
0}}} for both the first and the second pass or if you use {{{-an}}} for
both passes or if you use the same audio filter for the first pass as for
the second?
Thanks for the suggestions; I am running those tests now.
