Really loving it, but as James said, the stream is kept opened

To correct this, I made a few changes in the JS code:

1. add the var track ; on line 4
2. retrieve the track on line 29 :      track = stream.getTracks()[0];
3. after the capture is fired (endCapture = true;), stop the track: track.stop()

It works OK but it leaves the camera  stream open and doesn't have functionality to close it. This means the app is constantly using the device camera after first use.
