Jumping to a specific frame

In the previous recipe, you learned how to control the speed of your movie. In this one, we'll take a look at how you can jump to a specific position inside the video file.

How to do it...

We'll start with the same code as in the first recipe, but we'll add a float variable named w, which we will use to draw a progress bar to the screen.

import processing.video.*;
  
Movie m;
float w;
  
void setup()
{
  size( 640, 480 );
  
  m = new Movie( this, "marbles.mov" );
  m.loop();
}
  
void draw()
{
  background( 0 );
  image( m, 0, 0, width, height );
  
  fill( 0 );
  noStroke();
  rect( 0, 0, w, 10 );
}

The movieEvent() function looks a little different. We'll map the current time of the movie to a value between 0 and the width of our sketch window and store it in the w variable.

void movieEvent( Movie m )
{
  m.read();
  w = map( m.time(), 0, m.duration(), 0, width );
}

In the mousePressed() function, we'll map the value of the mouseX variable to a range between 0 and...
