I am porting Stagefright to Linux Desktop

So far get to the point when files is opened, sniffed, extractor and codec are created.

However got stuck at point where Decoding should happen, it seems it is not executing and stream is not there:

    04-20 09:29:34.658 20080 20080 E MediaCodec: getBufferAndFormat - not executing
    04-20 09:29:34.658 20080 20080 W SimpleDecodingSource: [] could not get input buffer #0

Any ideas what I miss.

On Emulator is should work, since it has all the services, so I am wondering what I messed up, by modify the code or need to add.

Maybe somebody can hint me?


On Emulator:

Any ideas how to fix it?
