Features

• Support switching front and back camera
• Support changing captured video frames quality
• Support changing device orientation

Notes

• Because UI components could be only updated in main thread, please use DispatchQueue.main.async {} to update UI in the delegate function.

    func didCaptured(image: UIImage) {
        // UIImageView can only be updated in main thread
        DispatchQueue.main.async {
            self.imageView.image = image
        }
    }
