IOS4 and direct access to the camera
The iPhone SDK4 brought a lot of interesting features. Among them the direct access to the camera is a real asset for AR (Augmented reality) applications or in a more general way for all applications processing the image/video to modify it or extract informations. I played around with the new related APIs so I'm going to tell you more about it and share some snippets showing how to use these APIs. If you want to know more about the AVFoundation framework, AVCaptureDeviceInput, AVCaptureVideoDataOutput and AVCaptureSession this article is for you.
