Landscape mode

[omarojo]

Have you figure out how to take video/photos in landscape mode with GOUimage2 ? I dont see any parameters to enable landscape mode in gpuimage2

[nateemma]

Not exactly. The current code sort of works in landscape mode if you use the back camera. The aspect ratio is messed up though and I haven't had time to look at it. Landscape does not work with the front facing camera.

Actually, I may not have checked in that change since it was to the GPUImage code, I'll go look...

OK, so I made the following changes to Camera.swift, in GPUImage2/Inputs:

1. In the declarations at the top of the class:

/*** iOS 8
let cameraProcessingQueue = DispatchQueue.global(priority:DispatchQueue.GlobalQueuePriority.default)
let audioProcessingQueue = DispatchQueue.global(priority:DispatchQueue.GlobalQueuePriority.default)
***/
// post iOS 8:
let cameraProcessingQueue = DispatchQueue.global(qos: DispatchQoS.QoSClass.default)
let audioProcessingQueue = DispatchQueue.global(qos: DispatchQoS.QoSClass.default)

2. in the init routine

After:

    if (captureSession.canAddOutput(videoOutput)) {
        captureSession.addOutput(videoOutput)
    }
    captureSession.sessionPreset = sessionPreset

Add the following:

    // merged in changes to fix orientation issue with front camera
    var captureConnection: AVCaptureConnection!
    for connection in videoOutput.connections {
        for port in (connection as AnyObject).inputPorts {
            if (port as AnyObject).mediaType == AVMediaTypeVideo {
                captureConnection = connection as? AVCaptureConnection
            }
        }
    }

    if captureConnection.isVideoOrientationSupported {        
        let location = self.location
        let videoOrientation = captureConnection.videoOrientation
        let deviceOrientation = UIDevice.current.orientation

        if ((location == .frontFacing) || (deviceOrientation == .portrait) || (deviceOrientation == .portraitUpsideDown) || (deviceOrientation == .unknown)){
            captureConnection.videoOrientation = .portrait
        } else if (location == .backFacing) {
            captureConnection.videoOrientation = (deviceOrientation == .landscapeLeft) ? .landscapeRight : .landscapeLeft
        }
   }
