I am trying to create two windows, and play the movie on the sub-window.  
So far I’ve made the sub-window appear with Applet, but it does not play the movie.  
The mp4 file is located in the data file, and it appears fine on the main window.  
Please can someone help me with how to solve this?

```auto
import processing.video.*;
 Movie Mov;

void settings(){
  fullScreen(P3D);
}
void setup() { 
      
  String[] args = {"SecondApplet"};   
  SecondApplet sa = new SecondApplet();
  PApplet.runSketch(args, sa);
  
}
 
void draw() {
  background(0);
}   

    

public class SecondApplet extends PApplet {

  public void settings() {
    fullScreen(P3D);
  }
  
 void setup(){
   Mov = new Movie(this, "movie.mp4");
   Mov.play();
  }
  
void draw() {
   background(255);
   image(Mov,0,0);
    }
   
  void movieEvent(Movie m) {
   m.read();
  }
  }

```

Thanks for the replay,  
So there is no way I can make it work?

Yes I’ve implemented "–sketch-path=” argument passed to PApplet.runSketch():  
But it didn’t make any change. Works on the main window but not on the sub-window…

- Can you post your most recent attempt?
- Notice that only the main PApplet knows the correct _sketchPath_.
- The others need to know it from the main PApplet via "–sketch-path=”.

Have you tried with the default renderer? Using more than one window with `P2D` or `P3D` is a recipe for disaster as there’s a bunch of static stuff that isn’t thread safe. The other issue is that the integration between GStreamer and OpenGL in the latest video library is, to put it mildly, a complete mess!
