update method

void update()

This is called automatically and sets needsUpdate to true every time a new frame is available.

Implementation

void update() {
  throw('This is not implimented yet.');
  // final video = image;
  // final hasVideoFrameCallback = 'requestVideoFrameCallback' in video;
  // if ( hasVideoFrameCallback == false && video.readyState >= video.HAVE_CURRENT_DATA ) {
  // 	needsUpdate = true;
  // }
}
