connection_nc.connect(null);
var stream_ns:NetStream = new NetStream(connection_nc);
my_video.attachVideo(stream_ns);
stream_ns.play("video1.flv");

this.createTextField("fps_txt", this.getNextHighestDepth(), 10, 10, 50, 22);
fps_txt.autoSize = true;
var fps_interval:Number = setInterval(displayFPS, 500, stream_ns);
function displayFPS(my_ns:NetStream) {
    fps_txt.text = "currentFps (frames per second): "+Math.floor(my_ns.currentFps);
}
