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. 

-----------------------------

mingw32-binutils 2.20-1, mingw32-runtime 3.17-1, yasm 0.8.0-1

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.
