How to connect IP camera with Processing?

Hi everybody. I'm trying to connect Ip camera of VISTALINE with processing but I can not get live image in sketch. Console always shows: Unable to open I/O streams: Server returned HTTP response code: 502 for URL: http://192.168.0.129:80/axis-cgi/mjpg/video.cgi?resolution=320x240

The code & IP configuration of camera are shown as pictures below:

IPCapture cam;

void setup() {
  size(320,240);
  cam = new IPCapture(this, "http://192.168.0.129:80/axis-cgi/mjpg/video.cgi?resolution=320x240", "admin", "admin");
  cam.start();

  // this works as well:

  // cam = new IPCapture(this);
  // cam.start("url", "username", "password");

  // It is possible to change the MJPEG stream by calling stop()
  // on a running camera, and then start() it with the new
  // url, username and password.
}

void draw() {
  if (cam.isAvailable()) {
    cam.read();
    image(cam,0,0);
  }
}

void keyPressed() {
  if (key == ' ') {
    if (cam.isAlive()) cam.stop();
    else cam.start();
  }
}

Anybody can help me,please?
