Encountered a similar issue today that was corrected with information from ffmpeg issue 963: https://roundup.ffmpeg.org/roundup/ffmpeg/issue963
The input mkv I was working with had > 20 streams; changing MAX_STREAMS to 64 in libavformat/avformat.h in a recent checkout and rebuilding corrected the issue. ** Bug watch added: roundup.ffmpeg.org/roundup/ffmpeg/ #963 https://roundup.ffmpeg.org/roundup/ffmpeg/issue963 -- ffmpeg -i crashes with segmentation fault https://bugs.launchpad.net/bugs/301723 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
