Thank you for your replies. I've been skimming through stream.c, but to tell you the truth, I'm a bit confused where's the boundary between the codec and the RTP stream. In other words, which function (in stream.c) hands the frame from the codec to the RTP stream? Is it put_frame? or put_frame_imp?
