Class NaradaRTPConnector

java.lang.Object
  cgl.narada.samples.rtp.NaradaRTPConnector

All Implemented Interfaces:

Handler, javax.media.rtp.RTPConnector

public class NaradaRTPConnector
extends Object
implements javax.media.rtp.RTPConnector, Handler

An implementation of RTPConnector based on Naradabrokering RTP support. In initialization phase, this might fail. because when we register this client we are sending the message with UDP If that message of the response of that message get lost, then this client will not initialize Therefore it will not work.

setReceiveBufferSize

public void setReceiveBufferSize(int size)
                          throws IOException

Set the receive buffer size of the RTP data channel. This is only a hint to the implementation. The actual implementation may not be able to do anything to this.

Specified by:
