detect whether user allowed or denied access to camera

If you want to detect whether the user allowed or denied access to the camera, you can listen for the camera's status event (StatusEvent.STATUS), as seen in the following code:

var cam:Camera = Camera.getCamera();
if (cam != null){
  cam.addEventListener(StatusEvent.STATUS, statusHandler);
  var vid:Video = new Video();
  vid.attachCamera(cam);
  addChild(vid);
}
function statusHandler(event:StatusEvent):void{
   switch (event.code){
       case "Camera.Muted":
           trace("User clicked Deny.");
           break;
       case "Camera.Unmuted":
           trace("User clicked Accept.");
           break;
   }
}

The event parameter of the statusHandler() function contains a code property which contains the string "Camera.Muted" or "Camera.Unmuted" . If the value is "Camera.Muted" the user clicked the Deny button and Flash Player is unable to access the camera.
