Programmatically extracting a frame from a video in Flash

I need to write a small Flash app that will need to extract a video frame from a playing video. It will not need to be saved to the HDD of the user. I just need to get the image data and display it in th开发者_如何学Pythone Flash movie. The frame to extract will be chosen by the user, which is why I'd like to do this purely on the client side (though I know I could do it from the server side).

I've tried searching for solutions but I'm not getting any useful results. Being a Flash newbie I haven't got any code yet seeing as I wouldn't know where to start.

So Flash gurus, is there a way to do this?

If you take a 'screen grab' of a DisplayObject in flash using BitmapData's draw() method.

If you have something for displaying flv somewhere a bit to the right, or down, try something like:

var cloneData:BitmapData = new BitmapData(video.width,video.height,false,0x000000);
cloneData.draw(video);
//test
addChild(new Bitmap(cloneData));

Goodluck!

After reading Georges answer, this is what I came up with as proof of concept. Posting here so it doesn't pollute original question.

    bitdata.draw(video);
    var grabResult:Image = new Image();
    grabResult.x = 0;
    grabResult.y = video.height;
