Question

To take a picture using the webcam in windows 8 app by clicking on a button , i have written the following code in c#:

    private async void camera_Click_1(object sender, RoutedEventArgs e)
    {
        cam = new CameraCaptureUI();
        await cam.CaptureFileAsync(CameraCaptureUIMode.Photo);
    }

now the Camera app got opened when i clicked the button but it’s giving me a message:

This app needs permission to use your camera
you can change this in app's settings

What app’s settings should be changed?

Answer 1

With Using the Manifest Designer you need to add the following Capabilities into your Package.appxmanifest:

<Capabilities>
   <DeviceCapability Name="webcam" />
</Capabilities>

Note: The webcam capability only grants access to the video stream. In order to grant access to the audio stream as well, the microphone capability must be also added.
