Apparently Cingg then should supports NVENC via some dynamic linked
external Nvidia lib, equivalent to what we did for for QSV via
oneVPL support.<br>
While h264_nvenc.mp4 rendering works, h265_nvenc.mp4 fails with the
following errors, see detail below:<br>

Setup<br>
----------<br>
Booted BIOS and checked that the integrated Intel gpu and
multimonitor setup were enabled. <br>
Installed the suse-prime package for <font
face="Courier New, Courier, monospace">nvidia/intel gpu selection
(for NVIDIA optimus laptops with bbswitch support) and could then
run the command<br>
<br>
prime-select on-demand<br>
<br>
and verified that both the Intel and Nvidia drivers were available<br>
