NetStream.Play.StreamNotFound when connecting to my AMS

Ok founbd a way to adjust the code to work with a f4v file over rtmp.

However I am still not able to stream from an f4m. Can someone help?

import flash.media.Video;
var nc:NetConnection = null;
var video:Video = null;
var mNetStream:NetStream = null;

video = new Video();
this.addChild(video);

nc=new NetConnection();
nc.addEventListener(NetStatusEvent.NET_STATUS, onNetStatus);
nc.connect("rtmp://000.000.000.000/vod");
nc.client = this;


function onNetStatus(event:NetStatusEvent):void
{
     //Trace the value of event.info.code
     trace( event.info.code );
     /*Check for a successful NetConnection, and if successful
     call publishCamera(), displayPublishingVideo(), and displayPlaybackVideo()*/
     if( event.info.code == "NetConnection.Connect.Success" )
     { 
          mNetStream=new NetStream(nc);       
          video.attachNetStream(mNetStream);
          mNetStream.play("mp4:sample1_1500kbps.f4v");       
          mNetStream.client=this;
          mNetStream.addEventListener(NetStatusEvent.NET_STATUS, onNetStreamStatusEvent);
          mNetStream.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
     }
}

function onNetStreamStatusEvent(event:NetStatusEvent):void
{
     if (event.info.code == "NetStream.Play.Start")
     {
          trace("NetStream.Play.Start");       
     }
     if (event.info.code == "NetStream.Play.StreamNotFound")
     {
          trace("Video Not Found");       
     }   
     if (event.info.code == "NetStream.Buffer.Full")
     {           
     }
}

function onMetaData(metadata:Object):void
{
}

function securityErrorHandler(event:SecurityErrorEvent):void {
     trace("securityErrorHandler: " + event);
}
