I'm in the midst of writing some addons that wrap the various Xiph
libraries (libogg, libvorbis, libtheora, etc). So far I've been
wrapping the low level API and then I'll look at higher level
abstractions to make them easier to use.

I've got the decoding portions of libogg and libvorbis mostly done, to
the point where vorbis files can be played - although the code is
pretty ugly to actually play something since it's a very low level
API.

I've put it in a githib repository in an 'ogg' branch:

http://github.com/doublec/io/tree/ogg

The addons/Vorbis/sampes/play.io file will play an Ogg file containing
a Vorbis stream - ignoring any other stream in there.

Comments appreciated, otherwise I'll just carry on hacking way in the
direction I'm going.

I'm using the PortAudio addon to play the sound but I notice this is
hard coded to be at a sample rate of 44,100 and 2 channels. So Vorbis
files at this are are the only ones that will play right. Is there a
way of changing the rate/channels that I'm missing?

Chris.
