To be honest, I just added Theora because I needed a simple way to
multiplex streams. Also, it'd likely take a rewrite of oggmerge to make it
usable for multiplexed streams, I think it assumes a single logical stream
per physical stream, though I didn't have an in-depth look at this issue.

I did see references to Skeleton, I'll have a look at it. I didn't
realize it was
used widely - I've certainly not seen anything with it in it (though I don't
tend to download many Ogg streams, I encode test ones myself :)).

As for .ogv for Theora, do you mean Theora-in-ogg, or raw Theora ?
If Theora-in-ogg, then what about Theora multiplexed with other stream
types, like Vorbis, since a lot of videos will have sound embedded ?

Yes, I was going to leave it as is while keeping the header field there,
just in case. I do know, however, that people in eastern countries tend
to dislike utf-8 for the size it takes for their language, as it's been, er...
/optimized/ for the latin alphabet. I am also not clear if every code point
can be coded in utf-8, I'll have to dig that up.

Yes, this is a fair point, but then you have Vorbis, Speex, and FLAC,
each with its own particularities. Yes, Vorbis would probably yield bad
sound at the low bitrates Speex works at, etc, this is just an example.

I understand where you're coming from.

Thank you for your comments.
