// listen to player events and kill manual connection once we're streaming
    player.addEventListener("playing", playListener);
    player.addEventListener("stateChange", stateListener);
    player.addEventListener("ready", readyListener);
      
/* this is the hack: check once every frame if the NC has been defined inside the FLVPlayback component */  
    this.onEnterFrame = function()
    {
       if (player.ncMgr.getNetConnection() != undefined)
       {
          this.onEnterFrame = null;
          delete this.onEnterFrame;
          trace("got NC");

         subscribe(streamName);
       }
    }
         
    var nc:NetConnection;
    var serverName:String = "server.llnwd.net";
    var appName:String = "account_name/_definst_";
    var streamName:String = "live";
   
    var source_Str = "rtmp://" + serverName + "/" + appName + "/" + streamName;
   
   // start up by setting the contentPath (now called source in newer versions of the component)   
player.contentPath = source_Str;  
   
    function subscribe(name:String)
    {
       nc = player.ncMgr.getNetConnection();
         
       nc.onFCSubscribe = function(info:Object)
       {
          trace("onFCSubscribe: " + info.code);
          clearInterval(int_id);

          if (info.code == "NetStream.Play.StreamNotFound")
          {
             // handle error, retry after a few secs or similar          }
          else if (info.code == "NetStream.Play.Start")
          {
             //  we're successfully subscribed          }
          else
          {
             // handle error          }
       };
         
      
// not used right now      
nc.onFCUnsubscribe = function(info:Object)
       {
       }
         
       trace("subscribing to " + name);
       nc.call("FCSubscribe",null,name);
    }
   
   // can be used to unsubscribe from stream   
function unsubscribe(name:String)
    {
       nc.call("FCUnsubscribe",null,name);
    }
