The original goal was Ogg only for 2.0, and then adding mp3 back in in
2.1 or something.  I added support for format plugins internal to the
server, so I do plan on adding MP3 now at 2.0.  If you look at format.c
you'll see this abstraction.

The players all need a constant format.  They way they are all handling
streaming prevents them from being able to cope with a mixed http
stream.  Maybe in a few years they will be written better, although I
don't think there's much reason to add that feature.

The answer to your problem is probably to reencode on the fly or
beforehand so that you end up with your stream at one steady output
bitrate in only one format.
