I think you may be misunderstanding how these two classes work. 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?
