Question

I have 2 RTSP streams inputs, streaming the same camera but going from different network path, I would like to relay one or the other on the same output RTSP URL depending on network performance. (camera is moving between network AP).

The switch between input could be done from a parameter / env variable / http request or even when the first input source is lost (sourceOnDisconnect ?)

Is there a way to achieve this ?
Thanks !

Hello, my advice is: write a script that rewrites the configuration file every time you need to switch the camera.
The server will reload the configuration and switch the source.

Something like this (i wrote it in bash but it's practically pseudo-code that can be written in any language):

#!/bin/bash

choose_camera() {
    # set new_camera by running some algorithm
    new_camera=1
}

current_camera=1

write_conf() {
    conf=""
    conf+="paths:\n"
    conf+="  path1:\n"
    
    if [ $current_camera = 1 ]; then
        conf+="    source: rtsp://url1\n"
    else
        conf+="    source: rtsp://url2\n"
    fi

    printf "$conf" > rtsp-simple-server.yml
}

write_conf

while true; do
    choose_camera
    
    if [ $new_camera != $current_camera ]; then
        current_camera=new_camera
        write_conf
    fi

    sleep 1
done
