Getting an error installing Linux version

So Im trying to switch my channels DVR from a raspi 4 to my r620 server with 2x xeon E5 2640 and 16GB Ram.
I tried to do this command:
sudo adduser $(id -u -n) video && sudo adduser $(id -u -n) render
and got these errors:
r620@r620:~/channels-dvr$ sudo adduser $(clarkr32 -u -n) video && sudo adduser $(clarkr32 -u -n) render
clarkr32: command not found
adduser: The group video' already exists.* *r620@r620:~/channels-dvr$ sudo adduser $(clarkr32 -u -n) video* *clarkr32: command not found* *adduser: The group video' already exists.
r620@r620:~/channels-dvr$ sudo adduser $(id -u -n) render
adduser: The group `render' does not exist.
r620@r620:~/channels-dvr$ ls
2021.02.04.1931 data install.sh latest uninstall.sh

Try using usermod instead: sudo usermod -aG $(whoami) video

Also, to see which group memberships are necessary, see who actually owns your video hardware: ls -l /dev/dri

(And remember, when modifying group memberships, the changes are only reflected upon a new login, so you need to log out, and then log back in for the change to be picked up.)

r620@r620:~/channels-dvr$ ls -l /dev/dri

drwxr-xr-x 2 root root 60 Jan 23 17:45 by-path

Those instructions are for ubuntu. It seems like you're using some other OS and it doesn't have QuickSync support.

r620@r620:~$ lsb_release -a command
Usage: lsb_release [options]

lsb_release: error: No arguments are permitted
r620@r620:~$ lsb_release -a

Distributor ID: Ubuntu

r620@r620:~$

Checkout out ark.intel.com, it looks like that processor does not have QSV. (Although, I couldn't find a E5-2640 there, but I did come across the E5-2640 v2, and there is no mention of QSV.)

shoot my best bet is to keep it on my raspi4 then huh.

off this table, which feature am I looking to NEED most importantly when it comes down to QSV?
