I haven't done it, but I remember attending a WWDC session a year or  
two ago where they talked about QTKit, and gave a demo of the Leopard  
QTKit capture classes.

It looked very easy (like a couple dozen lines of code easy);  a lot  
easier than trying to use the old Sequence Grabber API.

I'd imagine you could get the code samples in the above document (one  
of which captures images from an iSight camera) working in CCL in  
fairly short order.

If you've done anything with QuickTime before, you'll want to review  
the notes on 64-bit support.

The old (rather funky, IMHO) C-based QuickTime API isn't available to  
64-bit programs.  QTKit is the only game in town.

(You may already know all this, but I've been wanting to try out the  
QTKit capture stuff, and I've been keeping these notes in my head for  
when I get the chance.)
