...323 channel driver please shed

A/V sync in Theora
...ingly to not let audio and video drift too
much.
What I do not understand is, how I could preserve timestamps when
encoding to Theora/Vorbis without dropping frames or resample audio.
>From what I know from Mplayer's Ogg demuxer, Theora's granulepos can
only represent multiples of the frametime. Vorbis's granulepos is
specified in units of audio samples.
Is ist valid for Vorbis packets to drift the granulepos to compensate
for A/V sync? That would mean that granulepos does not represent the
number of actually played samples any more. Seems like an ugly hack.
Any other ideas?
