We have a demo application “sapWatch” (in the “testProgs” directory) that 
listens to and outputs SAP announcements.  We don’t have a demo application 
that *outputs* SAP announcements; however, that should be easy to write (using 
an IP multicast “groupsock” object, and a “BasicUDPSink”).

However, I don’t recommend using SAP, because (1) it’s restricted to IP 
multicast networks, and (2) few media player applications support listening to 
SAP announcements.  Instead, I suggest using RTSP - i.e., including a RTSP 
server with your data source, as illustrated by our various “test*Streamer” 
demo applications (e.g., “testH264VideoStreamer”), and described in our FAQ:
