    {
        public MainWindow()
        {
            InitializeComponent();

            // Create a pixel buffer
            var pixelBuffer = new byte[1024 * 768 * 4];

            // Create a video media sample
            var videoMediaSample = new VideoMediaSample(pixelBuffer);

            // Update the pixel buffer or video media sample
            videoMediaSample.UpdatePixelBuffer(pixelBuffer);

            // Render the video content
            var videoRendererElement = new VideoRendererElement();
