Not if the muxer is supposed to be codec-agnostic.

So basically I said "ogg muxing doesn't need to know about the codecs";
You said "ogg fails horribly here", and you explained that as "separating actual
data and headers". Read the thread again - what you think is a failure has
nothing to do with whether or not the muxer is codec-agnostic.
So, unless you can show me exactly where ogg isn't codec-agnostic (ie; it's the
*codec* that uses the container - ogg - and gives info to the container, and not
the other way around), I'll go on believing the xiph guys that wrote the container.

AVI is not streaming. I don't see why AVI is important in a discussion

Not sure I follow. Why would you want AVI to prepare data for Ogg ?
Anyway, I'll take up the exact problem up from the top in my next mail,
since on IRC you seemed to indicate that you at first didn't understand
my specific problem.
