Yeah, i used code from this one to implement a video export. The problem now is to mix the video together with to audio files. One recorded via microphone at the same time as the video, and a separate one.

Yes. You can use the rendered frame from your openGL view as samples for compressing video. This is what happens in the QCTV sample code.

Ahh, that seems to do what i want to audio, but as far as i can read it can only use a camera as input device, and i use a qcview (which i of course should have stated in my previous post)

Could i use my current opengl rendering to get the video, qtkit to get the audio, and then somehow mix them both together using qtkit?

Take a look at the QTKit Capture Programming Guide: <http://developer.apple.com/documentation/QuickTime/Conceptual/QTKitCaptureProgrammingGuide/Introduction/chapter_1_section_1.html >

Hi,

My application records video using opengl, but i need to add two audio tracks to it. First i need to add microphone recorded audio to a short muic track, and then add the result to the video. How should i go about to accomplish this?

Thanks
