Which Objective-C framework do I have to use to record my screen?

Question

I'm already recording from my iSight from a python script using the pyobjc bridge and the QTKit framework.

Which framework/device/... should I use to capture the video of my screen instead of the built-in iSight?

P.S. I'm using Leopard (not Snow Leopard) and thus I don't have the Quicktime X API at my disposal.

Answer 1

OpenGL. There's sample code for this on Apple's developer site (SonOfGrab, IIRC).

As of Lion, you should use AVFoundation to record the screen.
