GStreamer neither keep rtsp alive nor re-connect to ip camera

[Ian Davidson]

I believe that 'keep-alive' is normally configured within the OS for the 
internet connection, so that 'user software' does not need to do anything.

I learnt this some time ago (on Windows XP) - but I would suspect that 
it applies across most OSs.
