StopNGo is a simple stop-motion animation QuickTime movie recorder that uses AVFoundation.

It creates a AVCaptureSession, AVCaptureDevice, AVCaptureVideoPreviewLayer, and AVCaptureStillImageOutput to preview and capture still images from a video capture device, then re-times each sample buffer to a frame rate of 5 fps and writes frames to disk using AVAssetWriter.

A frame rate of 5 fps means that 5 still images will result in a 1 second long movie. This value is hard coded in the sample but may be changed as required.
