Hello guys!!
First of all I'm very noob to this so be patient!
Well my question is simple (i think)... I'm currently using processing-1.0.9, what I'm trying to do is to play a video when a marker is placed with a webcam... I'm trying to use the Bryan Chung ( http://www.bryanchung.net/?cat=28 and also http://www.bryanchung.net/?page_id=415 ) post to help me do this but for some reason it doesn't work at all! I installed ARToolKit 2.0 and JMyron! This is the code i used:

I installed ARToolKit 2.0 and JMyron! This is the code i used:
- import JMyron.*;
import processing.video.*;
import processing.opengl.*;
import pARToolKit.SimpleARToolKit;
SimpleARToolKit ar;
int capWidth, capHeight;
JMyron m;
Movie mov;
PImage img;
void setup() {
size(400, 300, OPENGL);
capWidth = 320;
capHeight = 240;
m = new JMyron();
m.start(capWidth,capHeight);
m.findGlobs(0);
img = createImage(capWidth,capHeight,ARGB);
mov = new Movie(this,"VIDEOFILE.mov");
mov.loop();
mov.read();
ar = new SimpleARToolKit(this, capWidth, capHeight);
ar.loadPattern("patt.hiro", 80, 0.0f, 0.0f);
ar.register("showBox");
noStroke();
fill(200,200,0);
rectMode(CENTER);
frameRate(15);
}
void draw() {
background(0);
m.update();
m.imageCopy(img.pixels);
img.updatePixels();
hint(DISABLE_DEPTH_TEST);
image(img,0,0,width,height);
hint(ENABLE_DEPTH_TEST);
if (ar.findMatch(img,100)) {
ar.showObject();
}
}
void showBox(SimpleARToolKit _a) {
pushMatrix();
translate(0,0,-20);
beginShape(QUADS);
texture(mov);
vertex(-60,-45,0,240);
vertex(60,-45,320,240);
vertex(60,45,320,0);
vertex(-60,45,0,0);
endShape();
popMatrix();
}
void movieEvent(Movie _m) {
_m.read();
}
void stop() {
m.stop();
super.stop();
}
When i hit Run the preview window pops up satys for a few seconds and closes and then give me this error:
