I'm not the most educated in video/audio matters to advise here, but I know 
that if you use ffmpeg and specify '-acodec copy' it will do just that with 
the raw data.  I know you can use ffmpeg with streams, so some clever use of 
pipes may be required for your application.

Perhaps someone more knowledgeable can chime in here.
