Recording video from a QCView to .mov

Hi,

I'm trying to record video form a webcam input to a .mov file. I've made a simple quartz composition and loaded it in a QCView. I tried using code from the QCTV example bundled with XCode, but there are things I'm not really sure about there. For instance, do i need to use OpenGL for rendering frames to a file, or can i use something else, perhaps something a little easier to use?

When i do

[_glContext setView:qcView];

I get

2009-01-08 10:40:33.084 macsupport[4218:10b] invalid drawable

in the Debugger Console. Not really sure what it means.

A bit down, this line returns nil:

_exporter = [[FrameMovieExporter alloc] initWithPath:[savePanel filename] codec:codec pixelsWide:size.width pixelsHigh:size.height options:options];
