You're more or less right, but streaming Vorbis over RTP means replacing
the Ogg conatiner with the RTP header, and with chained Vorbis streams,
calculating the RTP timestamps would have to be done using a more
complex mechanism than simply copying the granulepos fields from
the Ogg pages. It would not work to allow the RTP timestamps to skip
back and forth in time.
