GPU video transcoding in the Intel processor does not work.

Generally emby works well, but the GPU transcoding does not work.

I have the OpenMediaVault system installed on the server.

Docker is running on the server.

And on Docker is running EMBY.

Installations I made according to


The user "emby" is created with id: 1000, and I added it to the "video" group (id: 44)

All transcoding goes through all 6 processor cores.

I do not know what I did wrong.

Did you specify the below in your docker run?

--device /dev/dri/renderD128

My docker-compose file is below which works with Vaapi in case it helps (obviously the ports,mounts and uid/gid will be different)

version: '2'
    image: emby/embyserver:beta
    restart: unless-stopped
      - PUID=112
      - GID=114
      - VIRTUAL_HOST=watch.domain.name
      - LETSENCRYPT_HOST=watch.domain.name
      - LETSENCRYPT_EMAIL=test@example.com
      - GIDLIST=44
      - VIRTUAL_PORT=8096
      - "9096:8096"
      - "8096"
      - emby_config:/config:rw
      - /media/:/media:rw
      - /dev/dri/renderD128

    external: true

      name: Backend

Docker is a bit  more difficult and will require setup on your part, for example see @zeimaf's post #9.


Did you also map the device, for example:

--device=/dev/dri/card1:/dev/dri/card0 --device /dev/dri/renderD129:/dev/dri/renderD128

This is just an example and may not work for you.

How do I check "vainfo" then return it to me (vainfo.jpg)

Something is wrong


Maybe somehow I need to install graphics card drivers (intel)

Yes this is very possible. Can you do that?

I managed to find out more about this problem.

Debian 9 "stretch" does not have a driver for Intel's 8th generation "Coffee Lake" processors. i965-va-driver version (1.7.3-1)

Only in Debian 10 "buster" is the driver for new Intel processors. i965-va-driver version (2.2.0 + dfsg1-2)

OMV 4 is based on Debian 9.

I added drivers for graphics from Debian 10 to Debian 9 (OMV).


vainfo after installing drivers from Buster

It looks like everything is ok.


But hardware transcode in EMBY still does not work.

I attach the EMBA logs in the attachments.


It is not easy to run EMBY on Docker on OMV :)

I did not come up with this idea.

Do you know how to install these gpu drivers in the docker?

Have you mapped the device properly? To do so, simply use --device=/dev/dri/card1:/dev/dri/card0 --device /dev/dri/renderD129:/dev/dri/renderD128

Of course, adapt the number avec cardX and renderDXYZ to match your system.

Not sure if you got this problem fixed. Others mentioned adding devices, nobody mentioned /dev/dri permissions?


If use portainer to manage docker. Edit Emby, find Runtime & Resources Tab. Add Device - > /dev/dri Rebuild your container.

Permissions so container can talk to igpu = chmod -R 777 /dev/dri (rebuilt on server boot, best to add in to compose/boot scripts)


Hope that helps!

I found a message in the EMBY log: "Failed to open the drm device /dev/dri/renderD128"



I also set the permissions for this directory.
My user for Doker also has full permissions for this directory

            "DeviceIndex": 0,
