How to load a ByteArray FLV in OSMF?

Question

I'm working on a local application ( it's not a website or nothing related ) and I have various FLVs with a very simple encryptation method (just like adding 10 at each byte).
I can load/play them using NetStream.appendBytes() after my decrypt, but that happens only after I read all video data.
What I really need is to stream those videos from a remote url, and decrypting while receiving data, using a OSMF player that I already have.
This is my current code just to play my decoded FLV byte array
private function playBytes(bytes:ByteArray):void
            // detecting it's header
            if (bytes.readUTFBytes(3) != "FLV")
                _text.appendText("\nFile \""+ file +"\" is not a FLV")
                return void;
            bytes.position = 0;
            netConnection.connect(null);
            netStream = new NetStream(netConnection);
            netStream.client = { onMetaData:function(obj:Object):void { } }
            video.attachNetStream(netStream);
            addChild(video);
            // put the NetStream class into Data Generation mode
            netStream.play(null);
            // before appending new bytes, reset the position to the beginning
            netStream.appendBytesAction(NetStreamAppendBytesAction.RESET_BEGIN);
            // append the FLV video bytes
            netStream.appendBytes(bytes);

I looked at it a couple of month ago and, frankly, don't remember exact package that takes care of it. I don't have OSMF code on this machine - so I cannot look into it now.
I doubt there are many resources on the web regarding this. This is a very specialized functionality and very few people attempted to do what OSMF does. We have figured out certain aspects but were not able to completely replicate it. Again, it is a very daunting task to search of byte offsets and match with file format specs.
