Thanks for the tip.
To be honest, I'm hacking on a personal project for fun, security isn't
really a concern.
Raspberry Pi (which I'm using) recommends placing startup scripts in
rc.local in its official documentation:
However, if /dev/video0 can't be recognized as root, I'll follow your
advice and run my Ffmpeg command elsewhere.
