Requirements for using NetStream.seek()

Question

I'm using a NetStream class to play video using Video class or stage video , there is no seek bar to backward or forward video , i add seek bar to video but the seek function not work exactly , it give me a wrong time of seeking . ns.seek(mySeekTime) i wondered if it possible to make my own seek bar with exact seeking , i get the video from server , is server affect on seeking for video ?

        private function onClick(event:MouseEvent):void
        {
             if (event.currentTarget is Group)
             {
                 var myGroup:Group = event.currentTarget as Group;
                 if ( myGroup.mouseX >= 100)
                  {
                     mouseClickedXPos = myGroup.mouseX;
                     ns.inBufferSeek = true;
                     var seekTime:Number = (mouseClickedXPos-100) * (totalTime/(controlBarControls.width-100));
                     ns.seek(seekTime);     
                     myRect.graphics.clear();
                     myRect.graphics.beginFill(0xFF0000);
                     myRect.graphics.drawRect(controlBarControls.x+100,controlBarControls.y,mouseClickedXPos-100, rect.height);
                 }  
             }
        }

Here seek bar is myRect shape i draw it after Event.ENTER_FRAME .

problem : the time ns.time() will not change to new time we updated by seek(seekTime)

You will get more responses if you post code, and the exact problem you are having. — Cory Kendall, Apr 15 '13 at 08:00

Did you try to add keyframes to the video in ex. Adobe Media Encoder? It seems that seek function uses keyframes to locate the time.

NetStream can only seek to keyframes. If you have keyframes every six seconds and then seek to time 10 the video will end up playing at time 6. – Nathan Jun 17 '13 at 19:46
