[MPlayer-dev-eng] [PATCH] Null pointer reference in ad_liba52.c:62

["Ryan Steele" <rgsteele@xxxxxxxxx>]

This patch has also been submitted to Bugzilla:
http://bugzilla.mplayerhq.hu/show_bug.cgi?id=1089

I'm running the latest svn on x86_64 Hardy Heron. When attempting to
play an HD-DVD rip, mplayer crashes with a segmentation fault at
libmpcodecs/ad_liba52.c:62.

62              int c=demux_getc(sh_audio->ds);

(gdb) print sh_audio->ds
$4 = (demux_stream_t *) 0x0

See the Bugzilla bug for the complete backtrace. sh_audio->ds isn't
getting initialized before the first call to reinit_audio_chain() in
mplayer.c.
