>What is the difference between PassiveServerMediaSubsession and
>OnDemandServerMediaSubsession?

Short answer: Use "PassiveServerMediaSubsession" for streaming via 
multicast.  Use "OnDemandServerMediaSubsession" for streaming via 
unicast.

Slightly longer answer: Use "PassiveServerMediaSubsession" if you 
want to stream to an existing, already-set-up destination (i.e., 
"RTPSink"), using the same destination each time a client connects. 
Use "OnDemandServerMediaSubsession" if you want to stream to a new 
destination ("RTPSink") that is created for each new client.
