Hmm. Well enough, then - I didn't expect all of the OGM muxers to be
sensible enough to behave that way, particularly not given what I
remember having heard about OGM to begin with (and my somewhat
irrational lack of trust for things Windows-based, even open ones).

What are the source locations for (and the differences between) the two
sets of ogmtools? I've got the ones from Xiph CVS, but would certainly
be interested in any other possible source of progress and/or
improvement. (Though of course I'd prefer to mux video into Ogg, rather
than using the reportedly-not-quite-Ogg OGM...)

Yes, I know - I hadn't thought that through. I was working on the
assumption that "the file which is passed as audio stream to the muxer
is placed verbatim in the multiplexed file", which would require for
muxing purposes a non-containered stream. Fortunately that assumption
turns out to have been false.

I'm always so tickled whenever someone replies to my .sig....

I resurrected this line recently for Usenet; it's not as true as it used
to be, but the basic principle still applies.
