Hello, Is it possible to use face detection to trigger a video to play? if webcam detects a face, video plays im having trouble with achieving this

What have you tried? What are you using to detect the face? a webcam? do you know how to collect the video from the camera? Do you have some code that you have tested?

I use a webcam. I can get a video playback from the camera. I found a code that draws rectangles around the faces. I removed webcam footage from draw section. I got it working, but maybe you could suggest best settings for the video itself and should i improve something for it to run more smoothly?

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

Capture cam; 
OpenCV opencv; 
Rectangle[] faces;
Movie video1;

void setup() { 
  size(displayWidth, displayHeight);
  frameRate(30);
  background (0, 0, 0); 
  video1 = new Movie (this, "1.mp4");
  cam = new Capture( this, 640, 480, 30); 
  cam.start(); 
  opencv = new OpenCV(this, cam.width, cam.height); 
  opencv.loadCascade(OpenCV.CASCADE_FRONTALFACE);
  video1.loop();
}

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

void draw() { 
  opencv.loadImage(cam); 
  faces = opencv.detect(); 



  if (faces!=null) { 

    for (int i=0; i< faces.length; i++) { 
    image(video1, 0, 0 );

    }
  } 
  if (faces.length<=0) {
    textAlign(CENTER); 
    fill(255, 0, 0); 
    textSize(56); 
    println("no faces");
    text("stop", 100, 100);
  }
}

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

I want it to run fullscreen and the video to fit the screen and run smoothly
