Video tracking for progress bar using movie and ControlP5

Hello, I have been coding a progress bar using some examples that I found. The bar is almost done but it doesn't constantly update. Can someone assist me in getting it to update while the video is playing? https://forum.processing.org/two/discussion/8103/using-a-controlp5-slider-as-video-progress-bar#latest `

void setup() {
size(1280, 360);
cp5 = new ControlP5(this);
background(0);
// Load and play the video in a loop
movie = new Movie(this, "video.mov");
movie.play();

movie.speed(speed);

 //Progress Bar
  ProgressBar p;
  p = new ProgressBar(cp5, "progress");
 p.setPosition(130, 345).setSize(350, 10).setRange(0,  (int)
movie.duration()).listen(true);
//callback listener for Timeline object
 p.addCallback(new CallbackListener() {
  public void controlEvent(CallbackEvent theEvent) {
   if(theEvent.getAction() == ControlP5.ACTION_PRESS) {
    float x = theEvent.getController().getPointer().x();
    float a1 = 0;
    float a2 = theEvent.getController().getWidth();
    float b1 = theEvent.getController().getMin();
    float b2 = theEvent.getController().getMax();
    float val = map(x,a1,a2,b1,b2);
    theEvent.getController().setValue(val);
    println("now change movie time to ", val, movie.time());
    movie.jump((float) val);
      }
    }
  }
  );
     // a toggle to switch between play and pause mode
     cp5.addToggle("play")
    .setPosition(10,375)
    .setSize(50,19)
    .getCaptionLabel().align(CENTER,CENTER);
 }
   void movieEvent(Movie m) {
  m.read();
 }
     void draw() {
   if (play) {
   // update the progressBar value/position
   // replace with audio-track position: progress = player.position();

   if (movie.available()) movie.read();
   progress = (int) movie.time();
 }
  }
      class ProgressBar extends Controller<ProgressBar> {
      public ProgressBar(ControlP5 theControlP5, String theName) {
      super(theControlP5, theName);
       setView(new ControllerView<ProgressBar>() {

       public void display(PGraphics pg, ProgressBar c) {
    pg.fill(!isMouseOver() ? c.getColor().getForeground():c.getColor().getActive());
    pg.rect(0, 0, c.getWidth(), c.getHeight());

    float val = map(c.getValue(),c.getMin(), c.getMax(), 0, c.getWidth());
    pg.fill(255);
    pg.rect(0, 0, val, c.getHeight());
  }
}
);
}

      public ProgressBar setValue(float theValue) {
     return super.setValue(constrain(theValue, getMin(), getMax()));
 }

  public ProgressBar setRange(int theStart, int theEnd) {
  _myMin = theStart;
  _myMax = theEnd;
  return this;
  }
}`
