Using RTPConnector and RTPManager in Relay server

Question

Hi
Reposting it as suggested:
If I pass RTPConnector object in RTPManager then api discourages using addTarget. So in this case my questions are:
1. Do I have to create multiple OutputDataStreams or mange with single OutputDataStream.
2. When does getDataOutputStream get called.
3. If I use one OutputDataStream how do I avoid sending packet to the destination that sent the packet.
I just want to pass the audio stream received from one endpoint to the other recipients in unicast mode.
-Thanks in advance and I sincerely appreciate your help.

1. Do I have to create multiple OutputDataStreams or mange with single OutputDataStream.You have to manage with a single OutputDataSteam because that's the format that the object gives you to follow.
2. When does getDataOutputStream get called.I have no idea, but I don't really think it matters when it gets called. That information is abstracted away from us.
What you need to know is that it will be called at least once, maybe multiple times, per instance of the RTPConnector, and that the RTPManager is going to call write on it to send out data, and receive on it to receive data.
3. If I use one OutputDataStream how do I avoid sending packet to the destination that sent the packet.
I just want to pass the audio stream received from one endpoint to the other recipients in unicast mode.Take a look at the following example code:
[http://java.sun.com/javase/technologies/desktop/media/jmf/2.1.1/solutions/RTPSocketAdapter.java]
Take special notice of the read / write functions. In this example, notice how it uses a UDPSocket to send packets, and that it addresses each one as it sends it out.
Well, for your example, you'll probably maintain a list of hosts to send to, and everytime a call to write is made, you'd create one packet for each host, and send them all out over a UDPSocket.
So, putting that all together...
When the RTPConnector is created, you can create some functions to add some data you need (ie, a list of targets) to your RTPConnector object.
You construct the output stream implementation in getDataOutputStream, so you can throw whatever data into that class you want before you return the reference to the RTPManager (ie, a list targets)
You control what happens when OutputStream.write is called, so you can just do whatever you want (ie, send a UDP packet to each of the list of targets)...
If you maintain your own list of targets to send to, then you just don't add yourself as a target. Same as if you were using the normal addTarget method.
