This code should get you start experimenting:

1. import java.awt.image.BufferedImage;
   import java.awt.*;
   
   PImage screenShot;
   
   
   
   void setup() {
     size(screen.width, screen.height);
     screenShot = getScreen();
   }
   
   void draw () {
     image(screenShot,0,0, width, height);
    
   }
   
   PImage getScreen() {
     GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
     GraphicsDevice[] gs = ge.getScreenDevices();
     DisplayMode mode = gs[0].getDisplayMode();
     Rectangle bounds = new Rectangle(0, 0, mode.getWidth(), mode.getHeight());
     BufferedImage desktop = new BufferedImage(mode.getWidth(), mode.getHeight(), BufferedImage.TYPE_INT_RGB);
   
     try {
       desktop = new Robot(gs[0]).createScreenCapture(bounds);
     }
     catch(AWTException e) {
       System.err.println("Screen capture failed.");
     }
   
     return (new PImage(desktop));
   }
   

You could specify the location of the videostream in your browser to capture it.


However, if you just share the link of your video, we can actually see what's possible.

I am also interested in this topic. I am trying to live capture - not download - videos from earthcam webcams in order to analyze them. for example http://www.earthcam.com/usa/newyork/timessquare/ but since they use flv I think screen capturing is the only way I guess?

hey tommy,
I'm sure you figured something out already but maybe anyone else is interested aswell. there is actually a great library by Federico Bartoli on processing.org called 'cbmodel' which I think is perfect for your needs
