Note that the RTSP server (actually, "ServerMediaSession" and subclasses) 
implementation already adds "a=control:" lines to its SDP descriptions - so 
you probably don't need to add new "a=control:" lines of your own.

But anyway, a session-level 'wildcard' "a=control:" line is added in 
"ServerMediaSession.cpp", and media-level "a-control:" lines (one for each 
media  'subsession' in the stream) are added in 
"PassiveServerMediaSubsession.cpp" (for multicast streams), and 
"OnDemandServerMediaSubsession.cpp" (for unicast streams).
