Xamarin MonoMac在主窗口上预览网络摄像头（AVCaptureVideoPreviewLayer）

Question

我创建了一个简单的Xamarin MonoMac Mac应用程序（裸骨1窗口）。我正在尝试将我的网络摄像头预览到应用程序的主窗口。我使用AVFoundation类来访问网络摄像头。

我可以成功连接到mac的网络摄像头，然后网络摄像头灯亮起，但主窗口上没有视频。

我的c＃代码

        session = new AVCaptureSession () { SessionPreset = AVCaptureSession.PresetMedium };

        var captureDevice = AVCaptureDevice.DefaultDeviceWithMediaType (AVMediaType.Video);

        var input = AVCaptureDeviceInput.FromDevice (captureDevice);
        if (input == null){
            Console.WriteLine ("No input - this won't work on the simulator, try a physical device");

        }

        session.AddInput (input);

        AVCaptureVideoPreviewLayer captureVideoPreviewLayer = new AVCaptureVideoPreviewLayer (session);

        **//----> preview layer onto Window here ?!**

        session.StartRunning ();

这解决了它 - 希望它会帮助某人......

            AVCaptureVideoPreviewLayer captureVideoPreviewLayer = AVCaptureVideoPreviewLayer.FromSession (session);

            this.Window.ContentView.Layer=captureVideoPreviewLayer;
            this.Window.ContentView.WantsLayer=true;

            session.StartRunning ();
