The first thing I’d try is using “openRTSP” <http://www.live555.com/openRTSP/> as a client (instead of VLC). Try recording the stream, both directly from the camera, and via the proxy server. In each case, rename the saved video file to have a “.h264” filename suffix, and try playing it with VLC. Also, please run the proxy server with the -V option, and send us the diagnostic output, so we can see if there’s anything unusual in the RTSP “DESCRIBE” response from the camera.
