macOS API functions to capture screen video?

[marcimatz]

Hello,

I am quite new to Mac programming and was wondering if the OSX provides any API functions that handles recording of videos from screen information?
I am developping in c++, and ideally require functions similar to:

bool initializeRecorder(int resolutionX,int resolutionY,const char* filename,int framerate);

bool addFrame(const char* buffer);

bool endRecorder();

Any fileformat is fine (e.g. Qt, avi, etc.). I am also interested if there is any 3rd party library that offers above functionality.
Thanks for any insight!!

If you are targeting Lion you must use AVFoundation.

Thank you for the reply sumpfmonster.

I actually also need the code working on previous versions of Mac OSX (say, from Leopard on)

Cheers

There is a Apple sample called "From a view to a movie":

It demonstrates the pre-AVFoundation way via OpenGL and QuickTime. Even though the sample is for 10.6, the demonstrated techniques should work without too much work on 10.5.
