iPhone Dev: Process each frame of a live recording movie for AR app?
<p>I'm doing research into AR on the iPhone and am trying to figure out how people are getting each frame of video? I'm wanting to figure out AR using computer vision( OpenCV ). So basically I will have a pattern on a piece of paper that I will find using OpenCV and place a graphic on top of the pattern.</p>

<p>I know about the movie class UIImagePickerController, but am unsure how you would go about getting to each frame. </p>

<p>Can someone point me in the right direction?</p>
