It seems, WebGL or Media Capture is not supported on the web browser. Try in other browser. It should be worked on Google Chrome or Firefox for desktop with Webcam. (Although IE11 has WebGL, but Media Capture is still not available. Hopefully IE will support it in near the future)
It seems your WebCam is not available. Try again when you setup the WebCam.
Allow access to the Webcam.
Get a marker. To do so, open the URL below in your Mobile Phone or Tablet.

Show the marker to the Webcam. You will get a AR Chocolate then!
