Is a VCR running in the background on an iOS 4 iphone?

Question

Am I developing an application that requires recording video in the background when a user listens to a music player in the application? Is it possible to automatically start the iphone VCR in the background without prompting the user to press the record button?

Answer 1

Take a look at the new AV Foundation framework in iOS 4.0, this framework provides (low-level) access to capture video from the camera (s).

The main class you'll need to use is AVCaptureSession, and you must set the output to either AVCaptureMovieFileOutputor AVCaptureVideoDataOutput.
