Hmm, well, AFAIK, for the Theora embedding in Ogg as defined by the
Theora spec, frametime is a constant.  Variable framerate is only
possible by using a short frametime, and injecting emtpy packets every
now and then to pad between actual frames.

So that's what I was referring to.  Did I overlook something?
