Issue when using Box2D and video libraries together

Hello,

I trying to create a sketch with both the Box2D for Processing and Video libraries.
I have some boxes moving around and colliding with each other, and I want to texture these boxes with some video. However, I get a very long error message as soon as I put in the line of code to tell processing which video file I want to use.

import processing.video.*;
import shiffman.box2d.*;
import org.jbox2d.collision.shapes.*;
import org.jbox2d.common.*;
import org.jbox2d.dynamics.*;


Box2DProcessing box2d;

int no_boxes = 7;

//All of our boxes
Box[] boxes = new Box[no_boxes];

//Boundry sides
Boundry[] boundry = new Boundry[4];

float angle = -PI/2;
float grav_rad = 30;

float boundr = 260;
float boundw = 30;

PVector direction = new PVector();

Movie mouth;


void setup() {
  size(800,800,P3D);
  frameRate(60);
  colorMode(HSB,360,100,100);
  noStroke();
  
  //Load the movie
  mouth = new Movie(this,"mouth1.mov");
  mouth.play();
  
  // Initialize box2d physics and create the world
  box2d = new Box2DProcessing(this);
  box2d.createWorld();
  
  //Create the boxes
  for (int n=0;n<no_boxes; n++) {
    boxes[n] = new Box(random(200,600), random (200,600));
  }
  
  //Create the boundries
  boundry[0] = new Boundry(400+boundr,400,boundw,2*boundr+boundw);
  boundry[1] = new Boundry(400-boundr,400,boundw,2*boundr+boundw);
  boundry[2] = new Boundry(400,400+boundr,2*boundr+boundw, boundw);
  boundry[3] = new Boundry(400,400-boundr,2*boundr+boundw, boundw);
  
  
  
}

void movieEvent (Movie m) {
  m.read();
}


void draw() {
  
  background(200,50,80);
  image(mouth,0,0);
  
  angle+= radians(0.3);
  
  direction.x = grav_rad*cos(angle);
  direction.y = grav_rad*sin(angle);
  
  box2d.setGravity(-direction.x, direction.y);
  
  camera(width/2.0, height/2.0, (height/2.0) / tan(PI*30.0 / 180.0), width/2.0, height/2.0, 0, 0-map(direction.x,-10,10,-1,1), 0-map(direction.y,-10,10,-1,1), 0);   //x, y, z -> need to change between x and y

  box2d.step();
  
  // Display all the boxes
  for (Box b: boxes) {
    b.display();
  }

  //display the boundries
  boundry[0].display();
  boundry[1].display();
  boundry[2].display();
  boundry[3].display();

}

Here is the error message I get:

Any ideas? I have successfully used both Box2D and video separately, but something about having them in the same sketch seems to be an issue.

Perhaps one of these past issues will be relevant?
