“VLC is not supposed to be run as root. Sorry.
If you need to use real-time priorities and/or privileged TCP ports
you can use vlc-wrapper (make sure it is Set-UID root and
cannot be run by non-trusted users first).”
This error says straight forward vlc can not be run as root privileged user.
Just edit /usr/bin/vlc
using hexedit (you need to install this app) and search for geteuid and replace it with getppid.
Save file & Exit.
