title: Asking for camera permission without turning the camera on
body: <p>Whenever I accept the permission to use the camera on the browser, my desktop camera will light up. I would assume this is because navigator.mediaDevices.getUserMedia() returns a stream on success, and that stream is straight from the camera.</p>
  
  <p>I do not want the stream from the camera instantly on acceptance of the permission.</p>
  
  <p>Is there a way I could ask for permission without having to use the camera "instantly".
  I would use the camera later.</p>
