I had only 720p *.mkv segfault vlc. However, some Macromedia Flash
Videos segfault too. All H264 (High). Sadly I can't get it to segfault
on purpose. If I play the file a second time it will run past the
previous segfault position without problems. Sometimes it will crash
later on. Sometimes it won't.
