It didn't work.  Is this supposed to turn on SO_REUSEADDR?  SO_REUSEADDR
isn't the issue here.  The problem is that RTSP opens 2 UDP sockets on
the same ports every time, so if you have 2 processes trying to use the
same 2 UDP ports, one process is going to fail.  The patch I submitted
would increment port numbers if they are in use.
