MPlayer segfaults when playing Ogg file containing Theora video and Vorbis audio

Description

Having build MPlayer from CVS with theora support, I can play ogg-encapsulated
videos encoded with Theora okay, but if there is Vorbis-encoded sound MPlayer
crashes (SIGSEGV) at demux_ogg.c:532. I think it may be reading audio or video
header as data, because I also get the error "Cannot find codec for audio format
0x73627276." Please see operating system/environment information and gdb
backtrace below (I have printed the expression I believe causes the SIGSEGV: the
sh member of the demux_stream_t *ds argument to that function; and have also
provided a link to a test file that shows the problem).

  • Severity changed from major to critical

I changed the priority of this bug after reading the list of bug reports--sorry
if I've guessed wrong. It seems like a crash preventing you from playing a
certain kind of file would be classified as "critical," but I may be mistaken.

67 audio & 175 video codecs

delete any codecs.conf on your system!!! This one is probably years old.
With latest CVS this is 86 audio & 197 video codecs.
