This is the error for vlc

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).
To run VLC as root VLC binary has to modify

First, you'll need a hex-editor,
apt-get install bless
Then open VLC binary with bless
bless /usr/bin/vlc
Search and change the geteuid string by getppid, save and exit
