Need help creating video class

Question

I have the following code (most of which came from adobe
sample code) that I'm trying to use to create a simple class that
will connect to a flash media server. But, I've never done classes
in flash before so I'm not sure how to do a few things.
1. In my connect method, I'd like to have it return a boolean
value determined by whether or not it was able to connect. But
since I am using addEventListener for the NetStatusEvent, I'm not
sure if I can do that or how.
2. Is there a way to make it so that if the value of my
sErrMsg variable changes, it throws some kind of event to the swf
that is using this class? I figured if I could do that, I could do
away with requirement #1.
Thanks.
package {
import flash.display.Sprite;
import flash.events.*;
import flash.media.Video;
import flash.net.NetConnection;
import flash.net.NetStream;
public class VideoPlayer extends Sprite {
private var vidUrl:String = "filename";
private var server:String = "rtmp:/localhost/app";
private var conn:NetConnection;
private var stream:NetStream;
private var vWidth:Number = 300;
private var vHeight:Number = 200;
private var string sErrMsg = "";
public function set VideoUrl(sVid:String):void{
vidUrl = sVid;
public function set FlashMediaServer(sFMS:String):void{
server = sFMS;
public function get ErrorMessage():String{
return sErrMsg;
public function VideoPlayer(){}
public function Connect():void{
if (server.length > 0){
conn = new NetConnection();
conn.addEventListener(NetStatusEvent.NET_STATUS,
statusHandler);
conn.addEventListener(SecurityErrorEvent.SECURITY_ERROR,
securityErrHandler);
conn.connect(server);
private function
securityErrHandler(event:SecurityErrorEvent):void{
sErrMsg = event;
private function statusHandler(event:NetStatusEvent):void{
switch (event.info.code){
case "NetConnection.Connect.Success":
connectStream();
break;
case "NetStream.Play.StreamNotFound":
sErrMsg = "Unable to locate video";
break;
case "NetConnection.Connect.Failed":
sErrMsg = "Unable to connect to server";
break;
private function connectStream():void{
if (vidUrl.length > 0){
var stream:NetStream = new NetStream(conn);
stream.addEventListener(NetStatusEvent.NET_STATUS,
statusHandler);
var video:Video = new Video();
video.width = vWidth;
video.height = vHeight;
video.attachNetStream(stream);
stream.play(vidUrl);
addChild(video);
private function onMetaData(infoObject:Object):void{
var key:String;
for (key in infoObject){
if (key == "width")
vWidth = infoObject[key];
if (key == "height")
vHeight = infoObject[height];
}

I would suggest going to the book Killer Game Programming by Andrew Davison. In his book he has several classes that can accomplish the effects that you want. There are full explanations and you can download the code.
Here is the link:

Ex. Page Flipping //Double Buffering & Page Flipping in Chapter 4
Sprite management //3D Sprite Chapter 18; Animated 3D Sprites Chapter 19
Collision Detection //Sprite Bounding Box & Defining a Sprite in Chapter 11
Rendering loop //Rendering the Game in chapter 4
