File #01: irrelevant
File #02: MPEG1, which has a short clip of a different MPEG1 inside it (?!).
FPS changes, frame counter changes etc. This changing point is
where interesting stuff happens.
Situation #01: ffmpeg12 handles changing more correctly than libmpeg2 (I'll
upload the file this evening)
Situation #02: the topic, actually. When this MPEG1 file is played AFTER
one or more previous files, it segfaults when it the MPEG
change occurs. Also, it doesn't quit, video window stays,
MPlayer hanged..
Debug output follows :
(gdb) run ~/x/lila.avi ~/x/a.mpg -vc mpeg12
