I may miss something, but I guess this is the important 
problem you should work on (see doc/examples).

Possibly unrelated:
In your source code, I did not find information which 
decoder you are using.
Some decoders (everything mpeg-related) output yuv, and 
if you want the data in rgb, you have to convert it 
(using the sofware scaler), others (some lossless formats) 
output rgb, that may already be the data you want.
