Flv and BitmapData

1

Hello !:}

I try to make a simple copy of a flv video in a new MovieClip using the BitmapData class.
Here is my code :


var video1:MovieClip = this.attachMovie("mcVideo","videoMC",1);
var objVideo = video1.v;
 
var _nc:NetConnection = new NetConnection();
_nc.connect(null);
var _ns:NetStream = new NetStream(_nc);
objVideo.attachVideo(_ns);
_ns.play("vid6.flv");
 
var bmd:BitmapData = new BitmapData(320,256);
video1._visible = false;
 
//video copy container
var mc:MovieClip = this.createEmptyMovieClip("try1",this.getNextHighestDepth());
mc._x = 400;
mc._y = 300;
 
this.onEnterFrame = function(){//make copy
  bmd.draw(objVideo);
  mc.attachBitmap(bmd,1);
}

The problem is that the “mc” movieClip show a half-sized video !!!
I don’t understand… Does someone has an idea ?

Thanks
