You should use this fork from AppUnite's AndroidFFmpeg. Much clearer build instruction. I've successfully built FFmpeg v3.0.2 using NDK 11c.

Another piece of advice, do the build on Ubuntu, it will save you a lot of brain cells. After you've successfully built it on Ubuntu you can copy the whole thing and use it on Windows.

See my Gist for some errors you may encounter.
