onPlayStatus as3 - actionscript-3

Question

New to this one. Have this code for viewing multiple netstream events. Want to use the onPlayStatus to loop the "flv/intro.flv" and for the rest of the videos, I would like them to return to the intro.flv after they are done playing, but I can't find anything that helps enough. Can anyone offer a link or some help with the function? Here is my code so far :
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
var metaDataListener:Object = new Object();
metaDataListener.onMetaData = function(meta:Object){
}
ns.client = metaDataListener
var myVideo:Video = new Video(800, 600);
myVideo.x = 0;
myVideo.y = 0;
addChild(myVideo);
setChildIndex(myVideo, 0);
myVideo.attachNetStream(ns);
ns.play("flv/intro.flv");
duetBTN.addEventListener(MouseEvent.CLICK, playVideo1);
vantageBTN.addEventListener(MouseEvent.CLICK, playVideo2);
cabrioBTN.addEventListener(MouseEvent.CLICK, playVideo3);
classicBTN.addEventListener(MouseEvent.CLICK, playVideo4);
laundryBTN.addEventListener(MouseEvent.CLICK, playVideo5);
resourceBTN.addEventListener(MouseEvent.CLICK, playVideo6);
industryBTN.addEventListener(MouseEvent.CLICK, playVideo7);
homeBTN.addEventListener(MouseEvent.CLICK, playVideo8);
function playVideo1(e:MouseEvent):void {
ns.play ("flv/duet.flv");
}
function playVideo2(e:MouseEvent):void {
ns.play("flv/vantage.flv");
}
function playVideo3(e:MouseEvent):void {
ns.play("flv/cabrio.flv");
}
function playVideo4(e:MouseEvent):void {
ns.play("flv/classic.flv");
}
function playVideo5(e:MouseEvent):void {
ns.play("flv/laundry.flv");
}
function playVideo6(e:MouseEvent):void {
ns.play("flv/resource.flv");
}
function playVideo7(e:MouseEvent):void {
ns.play("flv/industry.flv");
}
function playVideo8(e:MouseEvent):void {
ns.play ("flv/intro.flv");
}

Answer 1

You can attach an event listener to the NetStream object that detects when a video has finished playing.
var introPlayer:NetStream = new NetStream(nc); // nc refers to shared net connection declared earlier
var introVid:Video = new Video(800, 600);
ns.addEventListener(NetStatusEvent.NET_STATUS, checkStreamStatus);
function checkStreamStatus(e:NetStatusEvent):void {
switch (e.info.code) {
case "NetStream.Play.Complete":
playIntro();
break;
}
};
function playIntro():void {
addChild(introVid);
introVid.attachNetStream(introPlayer);
introPlayer.play("flv/intro.flv");
}
Have changed the code completely to match the set-up you were using originally. This is how you're supposed to do it, apologies for previous answer. This is the correct way of doing it though.

Answer 2

If NetStream.Play.Complete is not dispatched, replace it with:
NetStream.Play.Stop or NetStream.Buffer.Flush
