Rather than using VLC (which is not our software, even though it uses our 
software as its RTSP client), I suggest using our command-line RTSP client 
“openRTSP”, which is included in the LIVE555 software (in the “testProgs” 
directory.  See:
        http://live555.com/openRTSP/

Just run:
        openRTSP rtsp://192.168.1.157:554/main_stream
and see what happens.
