I have been experimenting with the new audio extraction API in QT.
I have some questions:
- What is the min version of OSX this works on. It does not seem to
compile on 10.2.8.
- How many audio extraction sessions can I have open on a movie? Some
other post suggested 1 only. If that is the case, then why is this
not documented a LOT better? Seems a very important restriction.
- Given the above, can I make a NEW movie referencing each audio
track I want data out of, and then start a new session on that movie?
Or are these APIs going to follow the reference and decide that there
is already a converter for that?
- If the above fails to work, can I open and close the converter
after converting a few thousand samples, reconfigure it, and repeat
thus multiplexing how many sessions I want open by repeating this
open and close with each session I want? What kind of performance hit
will I take?
- One other way... if I go into core audio directly, can I have more
conversion sessions open?
- I want to extract and convert the audio from a single track. How do
I specify this? I can see how to specify left or right etc, but that
mixes all left and rights together, but I want say the left of a
single track only.
That's all for now, thanks in advance if anyone has any answers...
