Launch RTMP stream on startup

[Four_Hills]

I’m trying to setup some Pi’s to run an RTMP stream at work on multiple TVs throughout campus.

I’ve setup a systemd .service and .timer to run a script at launch that references a RTMP stream, but VLC doesn’t allow for running as root. I’ve tried mplayer, but the service reports:

● stream.service - "Runs stream"

It would be safe to assume there’s an issue with the video driver, but running the target script which is just mplayer rtmp://(ip of stream) turns out fine.

I’m running it on a Pi 4 Model B, but here’s a quick neofetch just if someone had questions about the environment

Why do you want to run as root?

Please post your systemd unit file (. service).

I guess it runs too early.

Didn’t have any desire to run it in root, just forgot about the autostart folder.

Got it working by creating a .desktop file in /home/pi/.config/autostart that read

[Desktop Entry] 
Type=Application
Exec=cvlc -f rtmp://(ip of stream)

Thanks for your help!
