SOLVED: H265 qsv linux not working

[K4YN5]

I have a problem when trying to transcode h265 content with QSV. It doesn't show up as an option. I have the n100 cpu, and it should be capable of doing so. When QSV is deactivated, it runs, but it throttles. The files are on a good state so it's not their fault either. On the logs of the ffmpeg this show up

[AVHWDeviceContext @ 0x59eaeb70acc0] No VA display found for any default device.
Device creation failed: -22.
Failed to set value 'vaapi=va:,kernel_driver=i915,driver=iHD' for option 'init_hw_device': Invalid argument
Error parsing global options: Invalid argument

Does anyone know how to solve it?

What OS? And do you using any virtualization (docker, VM, LXC)?

Can you the full ffmpeg log via pastebin?

I am using arch Linux on bare metal and I have Jellyfin on a docker container.

You enabled AV1 encoding. The N100 does not support encoding AV1. Only decoding AV1.

I disabled it, however it still complains and doesn't work. The new log.

You still have AV1 encoding enabled.

Code:

-codec:v:0 av1_qsv

What did you disable?  There are two AV1 settings.  One for decoding and one for encoding.  See my screenshot below.  The box at the top is for DECODING, which the N100 supports, and the bottom box, labeled "Allow encoding in AV1 format", is for encoding, which the N100 does not support.

Thanks! I have been disabling the decoding and leaving the encoding enabled, however it still doesn't work.

On the docker compose I haven't added any special group, render video etc., I've been seeing people adding them on some Reddit posts, could that be the cause from the error?

[TheDreadPirate]

Almost certainly. You have to both pass in the device and pass in the render group ID.

My docker compose for reference.

Code:

jellyfin-prod:
    image: jellyfin/jellyfin:10.9.11
    container_name: jellyfin-prod
    user: 1002:1002
    group_add:
      - "993" # Intel render group
    networks:
      blackmoon:
        ipv4_address: 172.16.100.10
    expose:

    volumes:

      - ./jellyfin-prod-data/cache:/cache
