How to use?

When the user "unmute" webcam on Flash, the library calls cameraUnmuted function:

var camera, canvas, context, imageData, pixels;

function cameraUnmuted(){
  camera = document.getElementById("flashcam");
  canvas = document.getElementById("canvas");
  context = canvas.getContext("2d");
  imageData = context.getImageData(0, 0, canvas.width, canvas.height);
}

Then you can call snapshot function anytime to get the image data:

function snapshot(){
  var image = imageData.data, i = 0, j = 0, pixel = 0, len;

  pixels = camera.snapshot().split(",");

  len = pixels.length - 1;
  while(len --){
    pixel += parseInt( pixels[j ++], 36);

    image[i ++] = pixel >> 16;
    image[i ++] = (pixel >> 8) & 0xff;
    image[i ++] = pixel & 0xff;
    image[i ++] = 255;
  }

  context.putImageData(imageData, 0, 0);
}

Security Issue

You probably need to visit the Flash settings on the Global Security Panel to run the demo on your local hard drive.

Search "flash global security settings" on Google to get more information.
