[FFmpeg-devel] Use ffmpeg as an Android stagefright plugin

[Fabio Fumi]

Hi Chih,

I've completed the merge of frameworks/av and framewroks/native and added 
the stagefright-plugins and ffmpeg to my project. I enabld the USES_NAM and 
built new system.

Startup wnet fine, but on YouTube test playback (which went just fine 
before), I get a crash (below).

Note how I haven't enabled he new ffmpeg codecs in media_codecs.xml and I'm 
using Google SW codec for h264:

        <MediaCodec name="OMX.google.h264.decoder" type="video/avc"/>

Suggestions?

thanks
Fabio
