[theora-dev] Multiplexed Ogg and header problems.

good question.  We have this functionality in our On2 server platform (TrueCast).  It works great for limited/variable bandwidth situations ie internet at say 150 - 400 kbits/sec.  Would love to see this in OGG.

  I there was a discussion on the vorbis list about Real Audio
  SureStream (tm) format. The basic idea was that they put multiple RA
  files with different compression levels. So when they have to switch
  the bit rate due to bandwidth changes, they choose from the streams
  they have. Since peeling is a long time away, it could be implemented
  with ogg vorbis multiplexing several times the same file with
  different compression levels. My question (and I think Monty can
  answer it) is how should the the presence of multiple concurrent
  vorbis streams be handled. Because if you have multiple audio tracks
  for a movie, or you have multiple compression rates it's very similar.
  The only problem seems to identify what's each of those streams for.
  In other word, how should I know that stream A is Swahili and stream B
  is Speranto, or that stream A is the -q3 compressed and Stream B is
  the -q1 compressed?
