This is a new android-ffmpeg project since it seems there were so many
different ways of doing it, it was confusing.  So here is my clean, easily
changeable, static ffmpeg creator for Android.  The result is a single
'ffmpeg' that is statically linked, so its the only file you need.


 1. Install the Android NDK r8 or newer
 2. On Debian/Ubuntu, run: apt-get install yasm bash patch make gawk
    (If you are on older releases of Debian/Ubuntu/Mint, like Debian/squeeze,
    then you will need to get newer versions of the packages automake,
    autotools-dev, and libtool.  You can download these from testing and
    manually install them. These are needed to provide the newest version
    of config.guess and config.sub, which only recently got Android support)


cd android-ffmpeg
git submodule init
git submodule update
NDK_BASE=/path/to/android-ndk ./

That should give you command line binary ffmpeg/ffmpeg, which is the only file
you should need.

Note: the 'make' build is setup to work with the Android NDK r8e. If you are
using an older version, or you are using the 32-bit NDK on a 64-bit system,
then you might need to set some variables manually as part of the command
line.  For example, using the 32-bit NDK on a 64-bit system:

    NDK_PROCESSOR=x86 ./

 Or using an older compiler version:



If you want to change which coders, decoders, muxers, filters, etc that are
included, edit and add/substract what you want.
