Only a few components in OSX are open source (Kernel, BSD inherited components, Grand Central Dispatch). Non of the Core Frameworks (Image, Storage, Animation, Graphics) are open source.
For anyone who has used iSightCapture and has been frustrated by the fact that it's released in object-code only format, here is qt-capture which is not quite as capable as iSightCapture (it doesn't have any command-line arguments) but does basically the same thing. Since it's just a proof-of-concept and not really finished code I've released it into the public domain.
It is an open source free, video editing software, effects, and compositing suite.
When I used it several months back, it was very unintuitive and I couldn't figure out how to use it. However, there are tutorials for Jahshaka now.
