Auto restart script based from https://stackoverflow.com/questions/49471595/improve-bash-script-for-checking-when-ffmpeg-hangs-streaming-ip-cam-rtsp-to-yout

This just got me where I needed to go on a solution. Thanks.

Really awesome! Got mine working with my custom rtmp server. Thanks a lot!

When I do this it also kills other streams. I want to do it for only 1 broadcast.

I am completely new to Pi's, scripting and such. Is this a command to execute or do i paste this (with changed URL) it in a config file?

These are shell scripts. It's a simple language to automate terminal commands.

Take a look at https://www.circuitbasics.com/how-to-write-and-run-a-shell-script-on-the-raspberry-pi/

Have fun!
