Hi everybody,

First, sorry for non perfect english...
I'm working on an interactive installation using TUIO for manipulate video with reactivision tags, i use OpenCV lib for playing video, but i don't understand why i can't play differents videos. I read this little test for explain my problem :

import hypermedia.video.*;

OpenCV opencv1;
OpenCV opencv2;
OpenCV opencv3;
int x = 160; 
int y = 90;

void setup() {
  size( 320, 200 );
  frameRate(25);
  background(10); // fond noir
  opencv1 = new OpenCV(this);
  opencv1.movie("T01.mov", x, y);
  opencv2 = new OpenCV(this);
  opencv2.movie("T02.mov", x, y);
  opencv3 = new OpenCV(this);
  opencv3.movie("T03.mov", x, y);
}

void draw() {
}

void keyPressed() {
      if ( key == 'a' ) // laisser la touche pressée
      opencv1.read();
      image( opencv1.image(), width/4, height/4);
      if ( key == 'z' ) // laisser la touche pressée
      opencv2.read();
      image( opencv2.image(), width/4, height/4);
      if ( key == 'e' ) // laisser la touche pressée
      opencv3.read();
      image( opencv3.image(), width/4, height/4);
}

pracessing play the third video if we press on "a", "z" or "e", how can we play different vids?
