Runs Video when typed in CLI or run script manually with ./ but will not work with systemd

[samthejam12]

I am trying to create a kiosk that has a video loop. This video gets cross checked with a md5 hash from a website so it needs to be launched from within a script after it does the hash.

I can type "cvlc --fullscreen --no-osd --loop --no-audio /home/pi/$(hostname).mp4" in the CLI and it will run the video fine.
I can put that command into a script called runvideo.sh and it works fine.

However when I run it with systemd, I just cannot get it working. Here are the error messages:

Not really sure, my experience with systemd is quite limited. I'd guess either the user it is trying to run as doesn't have appropriate permissions (member of video group I think) or some important environment variable isn't set.

I ran into this same issue and can confirm that adding the user to the video group solved the problem.
