You should repost your question on the QT API list - but one of the
features that is new in QT 7.2 is inserts - that is, you can get a
callback of the audio data from a movie as it is playing. You can
then apply your own processing, or whatever, you want to do with that
audio - I think its documented in the "What's New" document for that
QT release (and it was covered at last year's WWDC session). I think
that you could use that...

I apologize for bringing up a tangent question about the 'output
capture' question on this list, as I know this is more in line for
a quicktime question for one of their lists, but part of it has to
do with CoreAudio.
I do in fact program in CoreAudio, but I also use the Max/MSP/
Jitter application too for things I need to rapidly prototype. One
of the issues they point out with QT7+ is that the output of
QuickTime movies goes directly to CoreAudio where as in previous
versions, it could be siphoned off into their max/msp environment.
When I asked them about it, they said it was a core change of QT
that caused this.
My question is, are their any mechanisms to how QT at least output
to different locations or from now on, there are only plans to
output directly to CoreAudio? I have written a video mixer that
I'd love to implement some audio enhancements to (compression,
excitement, etc).
When someone mentioned DRM, this is the only thing I could think
of. Since QT is being used inside another program, I can't imagine
it would be a small number of people that would want this ability
(as in using QT libraries instead of recreating the wheel).
Again, sorry to steer off-topic here, but I find the people here
INCREDIBLY helpful and it does have a portion to do with CoreAudio
(at least from a QT standpoint).
Thanks!
