I've been using the SequenceGrabber stuff to deal with video input 
from a webcam. I'm currently trying to get that code (it uses FFI) to 
work under OS X.

Of course I've been ignoring the audio part of it, because I'm only 
interested in the video, but it's very similar. Once I get it working 
on OS X I'd be happy to send the basic SequenceGrabber code to anyone 
that it might help.
