just FYI:

as widely published, Apple's iPhone SDK includes a new version of
Xcode called 3.1 (beta), which may be installed separately but is only
distributed as part of the SDK download.

However, this new Xcode releases finally includes an updated linker,
which fixes the compilation problems of FFmpeg's ASM code on Intel-
based Macs. Thus, if you want a fast FFmpeg on Leopard, you the iPhone
SDK.

Can a developer who can compile FFmpeg for/on Mac OS X 10.5 using Xcode test?
...from the Xcode called 3.1 (beta) inside the new iPhone SDK Huh
Always read the XBMC online-manual, FAQ and search the forum before posting.
Do not e-mail XBMC-Team members directly asking for support. Read/follow the forum rules.
For troubleshooting and bug reporting please make sure you read this first.

Thumbs Up 
On a related topic matter GCC version 4.3.0 has been released.
Quote:Version 4.3.0 of the GNU Compiler Collection has its middle-end integrated with the MPFR math library, experimental support for the forthcoming C++0x ISO standard, GCJ now uses the Eclipse Java Compiler for Java parsing, all Java 1.5 language features now supported by both the compiler and at run-time, and new GCJ Java tools. GCC 4.3.0 also has performance tuning for the Intel Core 2 and AMD Geode processors. In addition, there is now support for Intel's SSE4.1, and SSE4.2 instruction sets. There are many more changes, so be sure to check out the GCC 4.3 change-log:

What I think this new Xcode version 3.1 (beta) is suppose to do is enable FFmpeg (libavcodec/libavformat) to be compiled with MMX without building FFmpeg as a static libraries but instead as a shared libraries (like they are for XBMC for Linux and the Xbox). I asume shared libraries is prefered?

Right? Huh
