I wrote some basic functions in ActionScript in order to use RTMFP:

import flash.events.NetStatusEvent;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.ui.Keyboard;

private var serverAddress:String = "rtmfp://p2p.rtmfp.net/";
private var serverKey:String = "xxxxx";
private var netConnection:NetConnection;
private var outgoingStream:NetStream;
private var incomingStream:NetStream;

private function initConnection():void {
    netConnection = new NetConnection();
    netConnection.addEventListener(NetStatusEvent.NET_STATUS, netConnectionHandler);
    netConnection.connect(serverAddress + serverKey);
}

private function netConnectionHandler(event:NetStatusEvent):void {
    receivedMessages.text += "NC Status: " + event.info.code + "\n";

    //Some status handling will be here, for now, just print the result out.
    switch (event.info.code) {
        case 'NetConnection.Connect.Success':
            receivedMessages.text += "My ID: " + netConnection.nearID + "\n";
            break;
    }
}

private function sendInit():void {
    outgoingStream = new NetStream(netConnection, NetStream.DIRECT_CONNECTIONS);
    outgoingStream.addEventListener(NetStatusEvent.NET_STATUS, outgoingStreamHandler);
    outgoingStream.publish("media");

    var sendStreamObject:Object = new Object();
    sendStreamObject.onPeerConnect = function(sendStr:NetStream):Boolean {
        receivedMessages.text += "Peer Connected ID: " + sendStr.farID + "\n";
        return true;
    }

    outgoingStream.client = sendStreamObject;
}

private function receiveInit():void {
    receivedMessages.text += "Initializing Receiving Stream: " + incomingID.text + "\n";

    incomingStream = new NetStream(netConnection, incomingID.text);
    incomingStream.addEventListener(NetStatusEvent.NET_STATUS, incomingStreamHandler);
    incomingStream.play("media");
    incomingStream.client = this;
}

public function receiveMessage(message:String):void {
    receivedMessages.text += "Received Message: " + message + "\n";
}

private function outgoingStreamHandler(event:NetStatusEvent):void {
    receivedMessages.text += "Outgoing Stream: " + event.info.code + "\n";
}

private function incomingStreamHandler(event:NetStatusEvent):void {
    receivedMessages.text += "Incoming Stream: " + event.info.code + "\n";
}

private function sendMessage():void {   
    outgoingStream.send("receiveMessage", toSendText.text);
}

private function disconnectNetConnection():void {
    netConnection.close();
    netConnection.removeEventListener(NetStatusEvent.NET_STATUS, netConnectionHandler);
    netConnection = null;
}

private function disconnectOutgoing():void {
    outgoingStream.close();
    outgoingStream.removeEventListener(NetStatusEvent.NET_STATUS, outgoingStreamHandler);
    outgoingStream = null;
}

private function disconnectIncoming():void {
    incomingStream.close();
    incomingStream.removeEventListener(NetStatusEvent.NET_STATUS, incomingStreamHandler);
    incomingStream = null;
}

Notes:

• initConnection initializes the NC, sendInit initializes the send stream
• receiveInit initializes the incoming stream based on the far peer id which I copy paste intoincomingID.text
• I print every results into receivedMessages.text
• I do not have firewall, nor NAT.
• The Adobe sample application (http://labs.adobe.com/technologies/cirrus/samples/) works perfectly.

The procedure I follow:

• Initialize NC on application 1. (sender)
• Initialize NC on application 2. (receiver)
• I initialize the sending stream (sendInit) on application 1.
• I copy the far peer id to application 2. and run receveInit.

After this, I execute sendMessage() which reads the message from toSendText.text.

Does not working. Why? What is wrong with my codes?

Thank you for every helpful answer in advance.
