Libnemesi is implemented with several nested threads dispatched for every session. Within the main thread we send requests to the various servers identified by an RTSP Controller structure, then a thread is dispatched to handle responses.

• First of all by calling rtsp_init we create an RTSP thread which handles incoming RTSP packets.
• The RTSP thread as soon as it receives a valid SETUP response from the server creates two different threads to handle RTP and RTCP packets
• The RTP thread as soon as its created initializes the various parsers for the session
• Then all the threads will run handling the packets of their specific layer until the RTSP thread for the given session is terminated.
