ffmpeg ndk r9 incompatibility

[LilyAcorn]

Compiling one of my apps for android using buildozer with ndk r9 gives the following error:

If you think configure made a mistake, make sure you are using the latest
version from SVN. If the latest version fails, report the problem to the
ffmpeg-user@mplayerhq.hu mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

Using ndk r8e, ffmepg compiles successfully.

I have only tested this using buildozer, not python-for-android directly. My application requirements in buildozer.spec is: requirements = kivy, ffmpeg.

Hi, I've rewrite part of the ffmpeg python extension to work with the latest 1.2.4 stable. Not the 2.1 yet. And it seems to works with NDK r9, as well as some optimizations are now activated (better performance on android!).

So clean your whole buildozer/python-for-android, pull if needed, and retry :)
