Yes, the solution that I proposed then was that rather than 
overriding "RTSPServer::RTSPClientSession::handleCmd_DESCRIBE()", you 
override "RTSPServer:: lookupServerMediaSession()".  You would parse 
the URL suffix (the "streamName" parameter) to get the "startTime" 
and "endTime" parameters that you want, and then create a new 
"ServerMediaSession" (with appropriate "ServerMediaSubsession"s) 
object, passing it the "startTime" and "endTime" parameters, which it 
would remember.

Then, for each new "ServerMediaSubsession" subclass that you're 
defining, you redefine the "createNewStreamSource()" virtual function 
to pass the "startTime" and "endTime" parameters to your source 
object, when you create it.

(Alternatively, you could redefine the "seekStream()" virtual 
function in your "ServerMediaSubsession" subclasses, and call that.)
