realtime effects on a video component

I have a flex 4.5 application that uses a mx:VideoDisplay component to display the webcam. how can I add realtime effects to that VideoDisplay component ?

for example: changing colors, particle/grain looks, wave effects, zoom and so on

thank you!

Changing colours can be done using any of the mx.graphics.shaderClasses.* by applying a blendMode
