I've figured that one out.  The vorbis extradata is split across three
packets, and the video data starts after the first of these.  This is
in violation of the ogg spec, which states that all extradata of all
streams must precede any non-extradata packets of any stream.  I guess
we should still deal with it somehow.  For some reason, it works with
tcvp.  I'm trying to figure out why.
