AVFoundation Camera Preview Wrong Orientation

I'm making a custom camera with a small preview area inside of the iPad, however, the stream in that previewing is rotated clockwise.

I have looked at both AVCam demo and the SquareCam demo on Apple and I don't see a solution in either. All of the AVFoundation orientation threads on StackOverflow are talking specifically about output orientation, not input orientation.

Here is the session code I'm using:

AVCaptureDevice *frontalCamera = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
    _session = [[AVCaptureSession alloc] init];
    [_session beginConfiguration];
    NSError *error;
    AVCaptureDeviceInput *input = [AVCaptureDeviceInput deviceInputWithDevice:frontalCamera error:&error];
    [_session addInput:input];
    _output = [[AVCaptureStillImageOutput alloc] init];
    [_output setOutputSettings:[[NSDictionary alloc] initWithObjectsAndKeys:AVVideoCodecJPEG,AVVideoCodecKey,nil]];
    [_session addOutput:_output];
    AVCaptureVideoPreviewLayer *previewLayer = [AVCaptureVideoPreviewLayer layerWithSession:_session];
    previewLayer.frame = self.imageViewCamera.bounds;
    previewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
    [self.imageViewCamera.layer addSublayer:previewLayer];
    _session.sessionPreset = AVCaptureSessionPreset640x480;
    [_session commitConfiguration];
    [_session startRunning];

Any help would be much appreciated!

This has been deprecated but you can change the orientation of your previewLayer counter-clockwise.

previewLayer.orientation = AVCaptureVideoOrientationLandscapeRight;

I'm not sure what the non-deprecated solution is though.

The layer’s orientation. (Deprecated in iOS 6.0. Use videoOrientation (AVCaptureConnection) instead.)

so use:

[[AVCaptureVideoPreviewLayer connection] setVideoOrientation: AVCaptureVideoOrientationLandscapeRight];

or

AVCaptureVideoPreviewLayer.connection.videoOrientation= AVCaptureVideoOrientationLandscapeRight;

The Apple docs for iOS 6 say to use videoOrientation (AVCaptureConnection) instead.
