title: RTSP Proxy implementation and testing
body: <p>I'm trying to implement an RTSP proxy server in order to analyse RTCP packets and dynamically switch to higher or lower bitrate streams (served by Wowza).
  Can someone recommend an existing opensource proxy (Java) and a client that allows me to set the proxy? I've tried to use VLC for testing but apparently VLC does not allow me to set the RTSP proxy. What alternatives exist, do I need to create my own client?</p>
