I know that Quartz Composer.app doesn't let you hear any audio in a video being played back (that has an audio track) **IN** the composer application itself.
But... when you play the composition back in your actual app, you **can** hear the audio track of the playing video. This I have tested. Works great.
I think I should probably now just concentrate on HOW to feed buffered (in-memory) video data into a quicktime movie much like a streaming movie would be played. Then figure out how to add the audio track to the movie from an in-memory audio buffer. And finally... feed the final a/v-complete qtmovie into my quartz composition. Obviously, for questions about the quicktime-specific stuff I'll need to write to the quicktime list.
But assuming I get all that going on.... how will i get the final qtmovie object (also residing in memory; not on disk) into my quartz composition?
The only way i can see to get movie data into a quartz composition is using the "Image with Movie" patch, but that takes a path to an actual file as its input parameter. Also there's the "Video Input" patch, but its only input options are from hardware video sources like webcams and such.
So how would I get an in-memory (non-file) qtmovie into a quartz composition?
Thanks.
