nVLC与集成摄像头崩溃

Question

我在C＃中使用nVLC包装器，使用带有集成摄像头和VS2013 / .net 4.0的Windows 7（64位笔记本电脑）进行流式传输。当我使用插入Windows 7笔记本电脑的USB网络摄像头时，一切正常。当我使用笔记本电脑附带的集成摄像头时，我发现了一个未处理的异常情况。以下是崩溃的详细信息

这是造成崩溃的代码。集成摄像头打开，我看到绿灯紧接着发生撞击。 USB摄像头工作正常。

    string videoDevice = "Integrated Camera"
    string videoDeviceOption = "dshow-vdev=" + videoDevice ;
    string output = @":sout=#transcode{vcodec=h264,vb=256,fps=30,scale=1,acodec=none}:udp{nux=ts,dst=127.0.0.1:8080} ";
    media = factory.CreateMedia<IMedia>(@"dshow://", videoDeviceOption, output);
    player = factory.CreatePlayer<IVideoPlayer>();
    player.Open(media);
    player.Play();
