Build instructions for FFmpeg
=============================

-----------------------------
Instructions for Mac OS X:

Built using i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5488)

In Finder, double click ffmpeg_source.zip
In a terminal, type:
    cd <directory>/ffmpegsource
    ./configure --enable-cross-compile --prefix=. --shlibdir=. --arch=i386 --target-os=darwin --extra-cflags="-arch i386 -mmacosx-version-min=10.5" --extra-ldflags="-arch i386" --disable-yasm --enable-shared --disable-static
    make
    make install

This will output the built files to the current directory.  To install, 
overwrite the application's copy of these files with the new ones. 

If building for debugging, add the following flags:  
    --disable-stripping --disable-optimizations --disable-mmx

The three patches tempnam.diff, strcasecmp.diff, nomt.diff found at http://fate.arrozcru.org/mingw32/patches/ were applied to the installed mingw32 headers.  The contents of these diff's can be found at the end of this file.

Extract ffmpeg_source.zip and in a terminal cd to the ffmpegsource directory.
Type:
    ./configure --enable-shared --disable-static --enable-memalign-hack --extra-cflags="-fno-common" --enable-win-unicode --disable-ssse3 --disable-amd3dnow --disable-amd3dnowext --arch=x86 --target-os=mingw32 --enable-cross-compile --cross-prefix=i686-mingw32-
    make
    make install

To install, overwrite the application's copy of these files with the new ones.
