Answer 1

There is a missing comma seperator:

}, //here

pixelScan: function() {

Answer 2

pixelScan isn't a function.

You're missing a comma separator before pixelScan.

Should be

this.myVideo.addEventListener("playing", function() {
        self.width = self.myVideo.videoWidth;
        self.height = self.myVideo.videoHeight;
        self.timerCallback();
        }, false);
    }
},
pixelScan: function() {
