Handle compressed headers. Fix inappropriate use of bytestream_flush().
Original commit message from CVS: Handle compressed headers. Fix inappropriate use of bytestream_flush(). Code cleanup. Added getcaps and _link functions for src pads. Extract and set the size,rate,channels correctly. Fix some of the caps to agree with avidemux and/or ffmpeg.
