Like I said, Documentation is an area needing work ;-)

Vorbis streams begin with three header packets.  First identifies the bitstream
and gives information like rate.  Second header is a vendor string plus a list
of 8-bit clean octet vectors.  The list is unbounded and vector length is
unbounded; the low-level API for setting/reading comments is the
'ogg_comment-xxxxxx' calls.  Third packet contains all the values for setting
up the decoder (including VQ codebooks).  The next packet is the beginning of
real data.

Also, to get you started, there are two API layers.  One is lower level (with
all the flexibility and verbosity that involves) found in codec.h, the other is
a decoder convenience lib (demonstrated in the xmms plugin and
'chaining_example.c') found in vorbisfile.h.
