Using USB camera instead of iSight

Passle

Hi,

I'm using this code for a facial recognition sketch, but it uses my inbuilt iSight camera instead of the USB camera I want to use. I tried looking for some workarounds, but no succes. How can I use my USB camera instead of the iSight?

import gab.opencv.*;
import processing.video.*;
import java.awt.*;

import ddf.minim.*;

Minim minim;
AudioPlayer soundtrack;

Capture video;
OpenCV opencv;

void setup() {

  size(640, 480);
  video = new Capture(this, 640/2, 480/2);

  opencv = new OpenCV(this, 640/2, 480/2);
  opencv.loadCascade(OpenCV.CASCADE_FRONTALFACE);  

  video.start();


   // always start Minim before you do anything with it
  minim = new Minim(this);
  //load a file, give the AudioPlayer buffers that are 2048 samples long
  soundtrack = minim.loadFile("laser.mp3");
  video.settings();
}

void draw() {
  scale(2);
  opencv.loadImage(video);

  image(video, 0, 0 );

  noFill();
  stroke(255, 255, 0);
  strokeWeight(3);
  Rectangle[] faces = opencv.detect();
  println(faces.length);

  for (int i = 0; i < faces.length; i++) {
    println(faces[i].x + ", FACE" + faces[i].y);
    rect(faces[i].x, faces[i].y, faces[i].width, faces[i].height);
    soundtrack.play();    
      delay(3000);
    soundtrack.rewind();



  }

}

void captureEvent(Capture c) {
  c.read();
}

void stop()
{
  // always close Minim audio classes when you are done with them

  soundtrack.close();
  minim.stop(); 
  super.stop();
}

you can't sorry

Thanks for the really helpful comment. I fixed it by finding out what the name of the usb is by using this code:

Capture video;



import processing.video.*;

void setup() {
  size(640, 480);

  String[] cameras = Capture.list();



  if (cameras.length == 0) {
    println("There are no cameras available for capture.");
    exit();
  } else {
    println("Available cameras:");
    for (int i = 0; i < cameras.length; i++) {
      println(cameras[i]);
    }

    // The camera can be initialized directly using an 
    // element from the array returned by list():
 video = new Capture(this, width, height, Vid, 24);
    video.start();  

  }      
}

void draw() {
  if (video.available() == true) {
    video.read();
  }
  image(video, 0, 0);
  // The following does the same, and is faster when just drawing the image
  // without any additional resizing, transformations, or tint.
  //set(0, 0, cam);
}

The name was "USB Webcam"

so then I added this to my original code:

  String Vid = "USB Camera";
  video = new Capture(this, 640/2, 480/2, Vid);

And it works :)

Full code here:

import gab.opencv.*;
import processing.video.*;
import java.awt.*;

import ddf.minim.*;

Minim minim;
AudioPlayer soundtrack;

Capture video;
OpenCV opencv;

void setup() {

  size(640, 480);
        String Vid = "USB Camera";
  video = new Capture(this, 640/2, 480/2, Vid);

  opencv = new OpenCV(this, 640/2, 480/2);
  opencv.loadCascade(OpenCV.CASCADE_FRONTALFACE);  

  video.start();


   // always start Minim before you do anything with it
  minim = new Minim(this);
  //load a file, give the AudioPlayer buffers that are 2048 samples long
  soundtrack = minim.loadFile("laser.mp3");

}

void draw() {
  scale(2);
  opencv.loadImage(video);

  image(video, 0, 0 );

  noFill();
  stroke(255, 255, 0);
  strokeWeight(3);
  Rectangle[] faces = opencv.detect();
  println(faces.length);

  for (int i = 0; i < faces.length; i++) {
    println(faces[i].x + ", FACE" + faces[i].y);
    rect(faces[i].x, faces[i].y, faces[i].width, faces[i].height);
    soundtrack.play();    
      delay(3000);
    soundtrack.rewind();



  }

}

void captureEvent(Capture c) {
  c.read();
}

void stop()
{
  // always close Minim audio classes when you are done with them

  soundtrack.close();
  minim.stop(); 
  super.stop();
}

Hope this is helpful for people who have the same problem.
