Real-time video filtering in a HTML5 <canvas> + <video>

HTML5 video has been added recently as an input format for canvas. Real-time pixel filtering in videos like setting the RGBa alpha channel of green pixels to become transparent is possible now as it has been before for still images. You'll need Firefox 3.5 for the live demo. Note that the compression artifacts are on flickr, the original is flawless.
