Need to seek a movie using the scroll wheel

[le-Screwball]

Is there way to call for the next frame of the movie only when a scroll wheel event is triggered ? The code i have so far updates to the current frame every time the scroll wheel is scrolled down(the movie seems to be playing in the background without being updated), not to the frame after the most recent frame displayed.

import processing.video.*;

Movie myMovie;

void setup() {
size(1920, 1080);
myMovie = new Movie(this, "1.mov");
myMovie.play();
}

void mouseWheel(MouseEvent event) {

float delta = event.getCount();
if (delta > 0) {
myMovie.read();
} else if (delta < 0) {

}
println(delta);
delta = 0;
}

void draw() {
background(0);
image(myMovie, 0, 0);
}
