Okay thanks for clarifying. I was actually just trying to model a media subsession based on what you did with the ProxyServerMediaSession and Subsession classes. They tied together very neat and was easy to add into the RTSPServer. But I see that this cannot work the same since I need to multicast.
But anyway, let's start from the beginning. Forget for a moment whatever code you've already written. What, specifically, do you want your test program to do? I have an incomplete spec, but one thing we are looking to have the ability to multicast an existing live source, possible from another RTSP server. I do have this working, but only as proof of concept (code isn't well organized). What I am really trying to do is familiarize myself with the server classes within Live555, so that I might come up with a clean design. What I was asking previously was really just for convenience sake. For example being able to create the RTPSink after I know the medium and codec that I am pulling in from the live source (i.e. if source is H264 I can then create the H264VideoRTPSink with the SPropParamSets overload) from within that SMS subclass. But nonetheless I can achieve this - just with a different flow. Many thanks and I appreciate your quick response.

A "ServerMediaSession" object represents a complete media stream (which can include one or more audio and/or video tracks), which is accessible - by name - via a RTSP server. Each "ServerMediaSession" object is added to a "RTSPServer" object, so that it can be accessed by clients. You should not need to subclass "ServerMediaSession". Each "ServerMediaSession" object contains one or more "ServerMediaSubsession" objects - one for each (audio and/or video) track in the stream. Furthermore, there are two kinds of "ServerMediaSubsession" objects: - A "PassiveServerMediaSubsession" represents a media data stream that already exists. This is usually a multicast stream. You usually don't need to subclass "PassiveServerMediaSubsession". - An "OnDemandServerMediaSubsession" represents a stream that is transmitted - via unicast - as a separate data stream, to each client that requests it. "OnDemandServerMediaSubsession" is always subclassed, depending on the particular media type (codec) and input source that you use for the stream. The "LIVE555 Streaming Media" code contains several examples of "OnDemandServerMediaSubsession" that can be used when streaming from files; developers can also write their own "OnDemandServerMediaSubsession" subclasses for streaming from other kinds of data source (e.g., an audio or video encoder). But anyway, let's start from the beginning. Forget for a moment whatever code you've already written. What, specifically, do you want your test program to do?
