Local connection

[tw-tracer]

Can I save flv file with NetStream.publish on my local drive?

I used this code, but file is didn’t saved

var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.publish("yourCamera", "record");
ns.attachVideo(Camera.get());

stop_mc.onRelease = function(){
this._parent.recording._visible = false;
this._parent.ns.publish(false);
}

I have make mistake or this impossible?
