seeking not working in flex 4.5 netStream byteArray - actionscript-3

Question

I am trying to play a flv video file in flex 4.5 with netStream byteArray. What I am doing is below:
Creating a netStream and video object
Attaching a netStream with video
Reading flv file in byteArray
Append byteArray in netStream using "appendBytes" method
Playing video
In this scenario Play, Pause, Stop functionalities are working fine with video.
But when I am trying to seeking in video then it is not working.
You can follow the code what I am doing by clicking on the link http://pastebin.com/fZp0mKDs
Can anybody tell me, where am I am going wrong to implement seeking.
Any code sample or any kind of help would be appreciated.

I got, the code below worked in my case
// onmetadata function get all timestamp and corresponding fileposition..
function onMetaData(informationObject:Object):void
{
for (var propertyName:String in informationObject)
{
if (propertyName == "keyframes")
{
var kfObject:Object = informationObject[propertyName];
var timeArray:Array = kfObject["times"];
var filePositionArray:Array = kfObject["filepositions"];
for(var i:int=0;i<timeArray.length;i++)
{
var tagPosition:int = filePositionArray[i];//Read the tag size;
var timestamp:Number = timeArray[i];//read the timestamp;
tags.push({timestamp:timestamp,tagPosition:tagPosition});
}
}
}
}
// onseek click get approximate timestamp and its fileposition
protected function seek_click(seektime:Number):void
{
var currentTime:Number = 0;
var previousTime:Number = 0;
for (var i:int=1; i<tags.length; i++)
{
currentTime = tags[i].timestamp;
previousTime = tags[i-1].timestamp;
if(previousTime < seektime)
{
if(seektime < currentTime)
{
seekPos = tags[i-1].tagPosition;
stream.seek(previousTime);
break;
}
}
}
}
// append bytes on seekposition
private function netStatusHandler(event:NetStatusEvent):void
{
switch (event.info.code)
{
case "NetStream.Seek.Notify" :
stream.appendBytesAction(NetStreamAppendBytesAction.RESET_SEEK);
totalfilePositionArray.position = seekPos;
var bytes:filePositionArray = new filePositionArray();
totalfilePositionArray.readBytes(bytes);
stream.appendBytes(bytes);
stream.resume();
break;
}
}
For inject MetaData keyframes into flv file.Use some injector tool, fe. FLV MetaData Injector

I think there is a problem in seeking of byteArray constructed after reading file. Just play you netStream directly, it works:
var fileName:String = "dummy-video.flv";
ns.play(fileName);
