ffmpeg with libfdk-aac

First step on window: install Mingw/msys

I use xhmikosr's version for example : http://xhmikosr.1f0.de/tools/

After that run msys.bat for Msys . now you can start building ffmpeg.

example you can try :

download and decompress (in Msys/home/your_name directory) http://sourceforge.net/projects/opencore-amr/files/fdk-aac/

and under Msys :
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg

cd fdk-aac-0.1.0
./configure --enable-shared=no
make -j4
make install
cd ..

cd ffmpeg
./configure --enable-libfdk-aac --enable-gpl --enable-version3 --enable-nonfree --enable-w32threads --enable-memalign-hack
make -j4

you have ffmpeg binaries in ffmpeg directory.
If you want others libs look at http://ffmpeg.zeranoe.com/builds/ for source files and do the same ( ./configure && make && make install )
and try ./configure --help to see the options.
