Question

I’ve done a Silverlight application that access my web cam.

Code:

public MainPage()
{
  InitializeComponent();      

  if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess())
  {
      snapshot.Visibility = Visibility.Collapsed;
      src.Start();
  }
  // Event Wiring
  //cameraButton.Click += new RoutedEventHandler(cameraButton_Click);
  photoButton.Click += new RoutedEventHandler(photoButton_Click);
  saveButton.Click += new RoutedEventHandler(saveButton_Click);

  // Setup Capture Source
  cameraBrush.SetSource(src);
}

Problem:

The function below always return false. I try to run in debug mode and in release mode, but without success.

if (CaptureDeviceConfiguration.AllowedDeviceAccess || CaptureDeviceConfiguration.RequestDeviceAccess())
  {
      snapshot.Visibility = Visibility.Collapsed;
      src.Start();
  }

Can someone help me ?

You need to be in Release mode its must. No debugger attached. https://stackoverflow.com/a/9258569/413032

What CaptureDeviceConfiguration.GetAvailableVideoCaptureDevices(); returns?
