[vlc-devel] Channel selection using Qtsound on Mac

[James Denness]

Hi all,

I've been struggling with this for a while, and I've exhausted Google's
vast knowledge, so I was wondering if someone could shed some light on this
issue for me.

I'm involved in a project where it's necessary to run 24 instances of VLC,
each capturing from one single channel of audio (selected from a 64-channel
interface), and broadcast this as an RTP stream. This works fine on Linux,
because ALSA does the heavy lifting when it comes to channel routing.
However, I can't work out how to instruct the qtsound module which channel
it should be capturing on, and a quick look through the source code
suggests that perhaps there isn't an easy way to do this at all. Is there a
better way to capture audio from a sound card on Mac, or if not, could
anyone suggest another way to ensure that I can select a particular channel
to capture using qtsound?

Thanks a lot for your time!

James
