[Solved] No HW transcode (again) on Asustor AS6704T (N5105 CPU)

Plex Media Server NAS & Devices

As I dig deeper into this problem, I think more and more that the problem is the same as this one :
https://forums.plex.tv/t/no-hw-on-asustor/814130/32

I ran some test by changing the devices section in my docker-compose.yml.
I tried this:

    devices:
      - /dev/dri/card0:/dev/dri/card0
      - /dev/dri/renderD128:/dev/dri/renderD128

But no effect…

But the /dev/dri/card0 on my AS6704T is a symbolic link to /dev/card0 which had this permissions :

crw-r--r--    1 root     root      226,   0 Apr 18 12:02 card0

So I ran a chmod 777 on it, and I set this:

    devices:
      - /dev/card0:/dev/dri/card0
      - /dev/dri/renderD128:/dev/dri/renderD128

and now inside my plex container I have:

crwxrwxrwx 1 root root 226,   0 Apr 24 17:57 card0
crwxrwxrwx 1 root root 226, 128 Apr 24 17:57 renderD128

But unluck I am, there is no results… still transcode without using HW…

I wanted to eliminate this version of Plex, so I installed the same docker-compose.yml (except for the volumes, and only the device /dev/dri on my Synology DS920+.
And, HW transcoding is working fine there !!!

That’s where I find myself thinking about a same issue we had in the past with Asustor NAS, and more specifically with N5105 CPU.

Is there anyone here can confirm this? Or have a solution?

Thanks in advance.
