BitmapData.draw() SecurityError: Security sandbox violation

Question

i am loading and playing a local video file with appendBytes() and when i call a bitmapData.draw() function
below exception comes up.
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw
cannot access null. No policy files granted access.
what should i do???....

Answer 1

Sir i already mention in my last message i test it with both relative and absolute.
Yes i khow relative paths works fine when i do some thing like this
<mx:VideoDisplay x="0" y="0" width="516" height="379" source="../user_data/uploads/cd73502828457d15655bbd7a63fb0bc8/v/1345023450-Action_.flv"/>
bitmap.draw works fine in above case but my scenario is different i am loading a complete video as bytearray before playing and play video from that bytes
private function fileLoaderComplete(event:Event):void
     //Pass the loaded bytes to player
       player.AddVideo(urlLoader.data);
//This is Add video Function in Player.mxml
public function AddVideo(VideobyteArray:ByteArray):void
                if(ns == null)
                    var nc:NetConnection = new NetConnection();
                    nc.connect(null);
                    ns = new NetStream(nc);
                   // ns.checkPolicyFile = true;
                    ns.soundTransform = new SoundTransform(0.0);
                    ns.client = this;
                    ns.addEventListener(NetStatusEvent.NET_STATUS, nsStatus);
                videoData = VideobyteArray;
                GetTags(videoData);
                ns.play(null);
                ns.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
                ns.appendBytes(VideobyteArray);
                video.attachNetStream(ns);
                playBar.TogglePlay(true);
i think its a bug in flash sdk 4.6 (Flash Player 11)
bitmap.draw function somehow conflicts with the appendBytesAction or appendBytes
