Question

我在访问物联网相机时遇到问题，我尝试创建访问摄像头的简单代码，从该摄像头查看实时流媒体。它适用于Windows-phone 10＆amp;＆amp; Windows 10。但是在IOT设备上试用时我遇到了错误，它说“没有设备找到＆＃39; 相机就像here in this link

这是代码

private async Task StartPreviewAsync()
    {
        try
        {
            mediaCapture = new MediaCapture();
            var allVideoDevices = await DeviceInformation.FindAllAsync(DeviceClass.VideoCapture);
            var count = allVideoDevices.Count;

            System.Diagnostics.Debug.WriteLine(count+"Video Capture Device");
            await mediaCapture.InitializeAsync();
            PreviewControl.Source = mediaCapture;
            await mediaCapture.StartPreviewAsync();
        }
        catch (UnauthorizedAccessException)
        {
            // This will be thrown if the user denied access to the camera in privacy settings
            System.Diagnostics.Debug.WriteLine("The app was denied access to the camera");
        }
        catch (Exception)
        {
            System.Diagnostics.Debug.WriteLine("MediaCapture initialization failed.");
        }
    }
    //protected async override void OnNavigatedFrom(NavigationEventArgs e)
    //{
    //    await CleanupCameraAsync();
    //}
    protected async override void OnNavigatedTo(NavigationEventArgs e)
    {
        StartPreviewAsync();

    }

对我的问题的任何建议？

Windows 10 IoT Edition目前支持Hardware Compatibility List上的有限数量的设备（请参阅Cameras部分）。不幸的是，如果您没有在那里列出相机，您将无法从UWP应用程序中使用它。据我所知，不支持Raspberry Pi原生相机。

UWP物联网，如何访问机载摄像头？，而不是USB摄像头
