[MPlayer-users] Crash in init_audio_codec with some files under Mac OS X since r27940

[Martin Bor]

Hi,

I recently noticed that some files that used to play fine now crashed  
the latest SVN versions of mplayer under Mac OS X. The error message I  
get is "MPlayer interrupted by signal 11 in module: init_audio_codec".  
The crash usually happens with .mkv's with a Vorbis or DTS audio track  
or .wmv's. I uploaded a 1 MB sample (COLORS.mkv) to ftp://upload.mplayerhq.hu/MPlayer/incoming/ 
  The full mplayer output is attached as output_mkv.txt and  
output_wmv.txt

I tried to compile mplayer with --enable-debug=3, which unfortunately  
resulted in a compile error in i386/cavsdsp_mmx.c (can't find a  
register in class 'GENERAL_REGS' while reloading 'asm'). So I added - 
g3 to the CFLAGS, OPTFLAGS and CXXFLAGS in config.mak. Running mplayer  
with gdb didn't reveal much, but the output is attached as mplayer.gdb

Checking out and compiling several revisions from Subversion, I found  
out that problem started with r27940, which added Yasm support to the  
build system. When I compiled r27940 and r27969 without Yasm, mplayer  
didn't crash anymore.

When I compared the Makefile of x264 (which also uses yasm) and  
mplayer, I noticed that the flags for Yasm differed. x264 uses "-f  
macho", while mplayer uses "-f macho32". When I changed this in  
configure and recompiled, mplayer didn't crash anymore. I attached the  
svn diff as configure.patch

So, while changing the configure worked for me, I don't really know if  
this a solution to the problem, considering what vmrsss wrote in http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2008-November/058948.html 
.

I hope that this is enough information. If there are any question I'll  
be more than happy to answer them. Below is an overview of my system.

Kind regards,
Martin
