I do know at start, and I have such a field too.
However, I was concerned about the RTP streaming case, where packets
may be lost, and the "other" container case, where they have to be
concatenated (and thus one needs a way to walk past them easily).
I reckon I'll just add a "header length" to headers past the first one, and
maybe on data packets as well. I'm not clear at all on what would happen
when not in Ogg, I need to think more about this case.
