Hello, > Took some time to bisect, first bad revision is libavcodec r22565, > commited at {2010-03-16 02:17:00}. The previous revision 22564 is OK > for me and this one leads to the crash on my system. After further searching, I realized my problem is already reported in ffmpeg BT: https://roundup.ffmpeg.org/issue1815 The proposed patch fixes the problem for me, so I will wait for a polished version to be commited in libavcodec...
