Only first frame loads on Android 4.4 (KitKat) Chrome

The video stream on the [demo](http://jonashartmann.github.io/webcam-directive/#/) does not load properly on Android Chrome (specifically, 2013 Nexus 7 on 4.4, KitKat). The first frame renders on the canvas, but nothing after that.

The HTML 5 Rocks [tutorial](http://www.html5rocks.com/en/tutorials/getusermedia/intro/) on getUserMedia does work fine. So I have hope that this can be fixed.

I have not had much of a chance to look into the issue. I noticed on my device and don't have an Android SDK for KitKat set up. But I thought I should at least make this known until I get the time to get a proper test environment working.
