[annodex-dev] CMML and multiple video streams?

CMML is a text format for describing video and audio files.

Are you asking whether it is possible to put multiple video streams
into an Ogg container? Or are you asking whether it is possible to put
multiple CMML tracks in to an Ogg container? Either of these is
possible, btw.

Even your example confuses me. Do you have on recording per band? If
so, there would be one CMML per band recording.

Or are you asking whether it is possible to switch between displaying
video and displaying annotations, while turning the other channel off?
This is really a display issue for the player. Within Firefox you can
get such flexibility by programming it into javascript.

Hope this helps?

Cheers,
Silvia.
