Install documentation suggestion for Ubuntu to avoid 'Failed to create hwaccel device' log error by adding user www-data to group render

[timrichardson]

I have installed zoneminder only twice, so please bear that in mind.

zoneminder v1.36.35

I installed on ubuntu 24.04 from the ppa.
I added
vaapi
to the Monitor Source DecoderHWAccelName field

I received these errors:

Failed to create hwaccel device. Generic error in an external library

to fix this, I needed to do:

sudo usermod -aG render www-data
and
sudo systemctl restart apache2

I no longer have the error in the logs

So my suggestion is to add that to the Ubuntu install logs

I don't think vaapi is actually doing anything, but does remove the error from the logs
