iphone - How to Programmatically Take Photos While Recording Video

Question

The iPhone 5S is capable of taking pictures while recording video and I am trying to figure out how I would do this programatically. I know I would be utilizing AVFoundation, however, I couldn't find anything in the programming guide regarding this. I have also checked the sample projects (AVFoundation-related) and it doesn't look like there is anything there that does what I am looking for. if you could help point me in the right direction that would be great.

Actually you can do it with any device that can record video:

• Create and configure a AVCaptureVideoDataOutput.
• Add it to your AVCaptureSession.
• Add a AVCaptureVideoDataOutputSampleBufferDelegate.
• Implement captureOutput:didOutputSampleBuffer:fromConnection: in the delegate and get the image with imageFromSampleBuffer:.

Some similar code can be found here, where images are captured at a given interval, but you only want one image.
