// Example 16-5: Scrubbing forward and backward in movie

// If mouseX is 0, go to beginning
// If mouseX is width, go to end
// And everything else scrub in between

import processing.video.*;

Movie movie;

void setup() {
  size(320,240);
  movie = new Movie(this, "cat.mov");
}

void draw() {

  // Ratio of mouse X over width
  float ratio = mouseX / (float) width;

  // The jump() function allows you to jump immediately to a point of time within the video. 
  // duration() returns the total length of the movie in seconds.  
  movie.jump(ratio*movie.duration()); 
  
  // Read frame
  movie.read(); 
  // Display frame
