------- Comment #8 from Jan Schmidt  2007-12-11 21:40 UTC -------
In 'byte-stream' mode, the SPS & PPS go directly in the data stream, usually
repeated regularly, like the Sequence header in an MPEG-2 stream. When it's
being sent as a stream of NALs, it's more common to expect the PPS & SPS to be
carried in the container and provided to the decoder separately, like this.

Most H.264 streams have exactly 1 SPS and 1 PPS, as this patch assumes, but
it's possible to have more, indexed by SPS/PPS id. I have no idea if the RTP
RFC covers that case?
