I am new to programming in Mac OSX. I need to do a very simple screen recording application similar to uShow, ScreenFlow and others, but with very basic settings and simple features. I would like some directions on where can I get some references on API areas, sample code, or some other information that might help me on this task.

I suspect that it is something related to the QuickTime API, but I would really appreciate some help here.

I have done this in Windows, but in Mac i am totally lost.

Anybody has any sample code or could tell which API I should start taking a look at....

There is a sample code code on the ADC site that do that:

http://developer.apple.com/samplecode/OpenGLScreenCapture/index.html

Description
Demonstrates how to capture the screen on Mac OS X using OpenGL. The sample shows how to grab frames using asynchronous texture fetching, a technique which is more complicated but offers better performance than synchronous capture using glReadPixels.


When performing asynchronous texture fetching, the resulting capture is saved to a movie file. Compression of the actual frames for the destination movie file is performed simultaneously with the capture but on a separate thread for better performance.
