Add more camera customization options

[Artem Kalinovsky]

Hi all,

Thanks for awesome CameraManager.

I have idea to add more customization for video and audio settings.

For example, add ability to set capturing area for camera.

Here some code, that express it:

-for video

    videoOutput!.videoSettings = [kCVPixelBufferPixelFormatTypeKey: Int(kCVPixelFormatType_32BGRA), AVVideoWidthKey : 100, AVVideoHeightKey: 100]
    videoOutput!.setSampleBufferDelegate(self, queue: dispatch_queue_create("sample buffer delegate", DISPATCH_QUEUE_SERIAL))

    if captureSession!.canAddOutput(self.videoOutput) {
        captureSession!.addOutput(self.videoOutput)
    }

-for photo

fileprivate func _applyPreviewLayerBounds(capturedImage image: UIImage) -> UIImage? {
        guard let previewLayer = previewLayer,
            let cgImage = image.cgImage else {
                return nil
        }
        let rect = previewLayer.metadataOutputRectOfInterest(for: previewLayer.bounds)
        let width = CGFloat(cgImage.width)
        let height = CGFloat(cgImage.height)

        let cropRect = CGRect(x: rect.origin.x * width,
                              y: rect.origin.y * height,
                              width: rect.size.width * width,
                              height: rect.size.height * height)

        guard let img = cgImage.cropping(to: cropRect) else {
            return nil
        }
        return UIImage(cgImage: img, scale: 1.0, orientation: image.imageOrientation)
    }

What do you think?

Thanks

@artemkalinovsky we think that this is out of scope for now
