I’m a Plex PASS subscriber and this is a new NAS machine intel N5095 I just installed, but I can’t seem to get the Plex hardware transcoding feature to work. I don’t know why. Here are the configurations of my new machine, could someone help me take a look and see if there’s something wrong with the settings?

I also edited the following configuration with google search
root@omvnas:~# cat /etc/modprobe.d/i915.conf
options i915 enable_guc=2
root@omvnas:~# cat /boot/config/modprobe.d/i915.conf
blacklist i915
sudo update-grub
update-initramfs -u -k all
reboot
but still use software transcoding!
I tested with mpv and it was able to hardware decode, so it looks like there is an issue with the Plex software.
