With XCode 3.0 on OS X 10.5.1, I get the dreaded:
i386/cavsdsp_mmx.c:447: error: can't find a register in class
'GENERAL_REGS' while reloading 'asm'
make[1]: *** [i386/cavsdsp_mmx.o] Error 1
make: *** [lib] Error 2
From looking at SVN, I can see you have the ffmpeg libraries precompiled and checked in. I assume this is because you needed to use a different tool chain?
I assume you haven't configured without mmx.. Any help would be appreciated!

./configure --prefix=/opt/local/ --enable-liba52 --enable-swscaler --enable-avfilter --disable-mmx --enable-libmp3lame --enable-gpl --extra-cflags='-I/opt/local/include' --extra-ldflags='-L/opt/local/lib'
assuming of course you have all the required dependencies (ports).

I had a look at the makefile from the XBMC OS X sources and it appears that they are being built with mmx enabled.
I'll keep trying. Any further hints from yourself or Elan would be appreciated.
Maybe Elan will chip in since he's the one who actually compiled it. I don't know if MMX is enabled or not. Based on r11434, it's possible that it is.

Sorry, I meant the config.mak (referenced by the Makefile) in
linuxport/docs/sources/dvdplayer/ffmpeg/ffmpeg (after untarring) has the following set:
ARCH_X86=yes
ARCH_X86_32=yes
HAVE_MMX=yes
HAVE_SSSE3=yes
Which seems to agree with the following line in the build_xbmc.sh file:
./configure --extra-cflags=-D_XBOX --enable-shared --enable-pp --enable-memalign-hack --enable-gpl --disable-static --disable-vhook --disable-en
coders --enable-swscaler
I have made some progress, in building the object files but build_xbmc.sh can't seem to build the shared library. Although, that might not be too much of a problem, since I'm after static libraries.. I'll keep at it.
P.S. - the cabac patch is purely for optimizing h264 performance and has nothing to do with getting it to compile.

I installed all the libraries following loosely: http://devblog.rorcraft.com/2007/8/18/ho..-and-linux (the patches aren't needed. if you bet compiler errors, trying converting text format using pico)
./configure --prefix=/usr --disable-vhook --enable-pthreads --enable-gpl --enable-libfaac --enable-libfaad --enable-libx264 --enable-libmp3lame --enable-libfaac --enable-libfaad --enable-liba52 --enable-libxvid
I successfully built a 64-bit binary too using:
./configure --extra-cflags=-m64 --extra-ldflags=-m64 --arch=x86_64 --prefix=/usr
(The 64-bit version is useless at the moment until I get it to use 32-bit liba52 binaries. I did manage a x264 64-bit library build using '--host=x86_64-darwin' but again, no A52 decoding makes it moot.)
Whoo hoo! A quick benchmark using a h.264/ac3 MKV rip yielded the following benchmark (/usr/bin/ffmpeg -benchmark -i /Volumes/HD/Film/Cars.mkv -f null -an /dev/null):
w/o MMX/SSE: 80 fps
w/ MMX/SSE: 154 fps
This was on a Mac Pro 8x2.8 Xeon.
Good luck!
Thanks

Thanks

What's the problem ? And by above, do you mean FFMPEG by itself or the FFMPEG configure that occurs when XBMC is configured ?

FFmpeg has always been a very experimental and developer-driven project. It is a key component in many multimedia projects and has new features added constantly. Development branch snapshots work really well 99% of the time so people are not afraid to use them.
Git Repositories
Since FFmpeg is developed with Git, multiple repositories from developers and groups of developers are available.

Releases
Approximately every 6 months the FFmpeg project makes a new major release. Between major releases point releases will appear that add important bug fixes but no new features. Note that these releases are intended for distributors and system integrators. Users that wish to compile from source themselves are strongly encouraged to consider using the development branch (see above), this is the only version on which FFmpeg developers actively work. The release branches only cherry pick selected changes from the development branch, which therefore receives much more and much faster bug fixes such as additional features and security patches.
