# There are a few ways to build this using the NDK. Using version r5b here as it introduces
# better support for standalone building, so we can use FFMPEG's configure and make and a
# minimal Android.mk to pull it all together

# should point to where your NDK is
NDK=~/android-ndk-r5b

# get ffmpeg
git clone git://git.ffmpeg.org/ffmpeg.git
cd ffmpeg

# build a standalone toolchain - you could install this to somewhere more permanent
$NDK/build/tools/make-standalone-toolchain.sh --install-dir=/tmp/android/toolchain
export PATH=$PATH:$NDK:/tmp/android/toolchain/bin
