How do i save a video (mp4 format) using AVCaptureVideoDataOutput?

I have set up the input, and the output for the AVCapture session and also the delegate

- (void)captureOutput:(AVCaptureOutput *)captureOutput didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer fromConnection:(AVCaptureConnection *)connection

is getting called. How do I convert the frames to a mp4 video file and save it?
