that video1.flv displays.
var connection_nc:NetConnection = new NetConnection();
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);
}
