This seems to be a symbol conflict. Both ffmpeg and mplayer ship their own, private copy of liba52 and if mplayer is linked against the system's ffmpeg this results the crash. Solutions would be disabling it in one of both or linking against mplayer's private copy of ffmpeg again.
Also it seems to be possible to lazy link liba52 in ffmpeg, I have to test if this fixes this crash... ** Bug 56609 has been marked a duplicate of this bug ** Bug 54269 has been marked a duplicate of this bug -- Crash when playing DVDs https://launchpad.net/bugs/53883 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
