As for why you need AVCaptureVideoOrientationLandscapeRight when the device's orientation is UIDeviceOrientationLandscapeLeft, that's because, for some reason, UIDeviceOrientationLandscapeLeft == UIInterfaceOrientationLandscapeRight, and the AVCaptureVideoOrientations are following the UIInterfaceOrientation convention.

Also, UIDeviceOrientation incudes other options like UIDeviceOrientationFaceUp, UIDeviceOrientationFaceDown, and UIDeviceOrientationUnknown. If you're having your interface rotate to match the device's orientation, you could try getting the UIDeviceOrientation from [UIApplication sharedApplication].statusBarOrientation instead.
