How to set up relaying of rtsp video stream from the camera from the internal network to the Internet?

Question

fmpeg

Hello!

Tell me how to correctly compose a command for relaying a video stream to rtsp from an ip-camera from the internal network through a server with vlc.

Camera -> ubuntu server -> client with vlc

Url of video stream from camera rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif

Ubuntu server with external ip xxx. xxx.xxx.xxx The command that I run on the server.

cvlc -d rtsp://admin:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif --loop --repeat --sout-keep "#rtp{sdp=rtsp:/ /xxx.xxx.xxx.xxx:8080/test.sdp}";

On the vlc client I enter rtsp://xxx.xxx.xxx.xxx:8080/test.sdp - there is no broadcast. There are no errors, the log is empty. Tried ffmpeg:

ffmpeg -i 'rtsp://onvif:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif' -f rtsp -rtsp_transport tcp rtsp://xxx.xxx.xxx.xxx;
Input #0, rtsp, from 'rtsp://onvif:[email protected]:554/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif':
