Good to know. So there must be another problem here, because I cannot
see any "TEARDOWN". 

I tried to #define DEBUG in RTPServer.cpp to see which messages are
being exchanged. I started the server, then a client:

  $ openRTSP -e 5 rtsp://admin:admin@cx7:7070/input1

Here is the server's output:

As you can see, no TEARDOWN command was triggered. Do I miss something?
