I kept on using plex 1.18.0.1846 but it seems to also be fixed with the latest plex 1.21.1.3830 and unraid 6.9 RC2

Thank you for your reply! Indeed! After updated to 6.9 RC2, everything works perfectly fine. I spent a lot of time debugging this.

 

Don't know whether it's a problem of older version of unRaid or Docker. I was trying out unRaid, but disappointed to see no response from unRaid in your thread. Also I found there's some other io problem with unRaid Docker running qBittorrent. I already switched to other NAS OS. But thank you very much for your reply!

Hi,
I have an issues with getting Hardware transcoding working with Plex versions higher than 1.18.0.1846-f62172e99. 

 

I have added the the following to my go file

modprobe i915 
chmod -R 777 /dev/dri

and to my docker I have added this extra paramters:

--device=/dev/dri

From the Plex docker the igpu seems to be available 

but every time I start any type of transcoding it is not in hardware.

 

If I add "intel_iommu=igfx_off" to syslinux.cfg then HW transcoding start working again but it is incredibly blockly and unwatchable.

I have also tried deleting iHD_drv_video.so as recommended on the Plex forum, which resulting in Plex showing HW transcoding is active, but the video never starts playing. 

 

My system is based on an ASRock J5005-ITX which as a Gemini Lake CPU should support HEVC 10bit transcoding. For Plex I am using linuxserver's repo.

 

Have anyone experience something similar or just have an idea how to fix it? 

 

I'm having exactly the same problem with J5040, have you found the solution?
