So I have an application that can currently capture video with the front facing iphone camera and then do some processing on the video feed real-time. What I’m trying to do, however, is make this process run in the background and put other controls onscreen. So for example, say I’d like to run the camera and process the image feed, but I want the user to see a black screen with some buttons on it. Any ideas on how to do this?

Heres an exemple code from Apple’s doc:

there is also the way to customize the camera interface.
