startMediaStream(captureAudio, width, height) → {Phaser.Video}
Instead of playing a video file this method allows you to stream video data from an attached webcam. As soon as this method is called the user will be prompted by their browser to "Allow" access to the webcam.If they allow it the webcam feed is directed to this Video. Call Video.play to start the stream. If they block the webcam the onError signal will be dispatched containing the NavigatorUserMediaErroror MediaStreamError event.
