Transcoding issues and hardware acceleration

[glassy]

Hello All,

I've been having issues with transcoding during a recent re-install of jellyfin through docker. The issue appears on any player that I've tried so far (web player on localhost, jellyfin app on webOS).
My host system is running arch, on an intel 10700K and an 7800XT (with mesa drivers). Jellyfin version is 10.9.7

What I am noticing is extremely high cpu usage even in 1080p videos, and 4k videos are almost unplayable (lets 5s buffering for 1s of playback).

My docker-compose looks like this:

Code:

services:
  jellyfin:
    image: jellyfin/jellyfin
    container_name: jellyfin
    user: 1000:1000
    network_mode: 'host'
    security_opt:
      - no-new-privileges:true
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
    group_add:
      - "989"
    volumes:
      - /home/iakovos/Git/config:/jellyfin-config
      - /home/iakovos/Git/cache:/jellyfin-cache
      - /mnt/MediaA/Series:/Series2
      - /mnt/MediaA/Movies:/Movies2
      - /mnt/one_tb_storage/home/iakovos/Downloads/Series:/Series
      - /mnt/one_tb_storage/home/iakovos/Downloads/Movies:/Movies
      - /mnt/one_tb_storage/home/iakovos/Downloads/Books:/Books
      - /mnt/one_tb_storage/home/iakovos/Downloads/AudioBooks:/AudioBooks

    restart: 'unless-stopped'
    extra_hosts:
      - "host.docker.internal:host-gateway"

I've followed this guide (https://jellyfin.org/docs/general/administration/hardware-acceleration/amd/) and I can see the following outputs for the commands listed towards the virtualization section.

Code:

sudo docker exec -it jellyfin /usr/lib/jellyfin-ffmpeg/vainfo --display drm --device /dev/dri/renderD128

Any ideas what could be wrong?

Can you share your ffmpeg log via privatebin.net? One guess is that you have HEVC unchecked. Meaning you are CPU decoding videos that are 8-bit HEVC.

You could also be audio transcoding and/or burning in subtitles. Both of which occur on the CPU.

But your ffmpeg log would show us what is going on.

Also, you are many versions behind.

Thanks,
my ffmpeg logs are here https://privatebin.net/?520f273c6fe0576f#cpjpK1PhgBYEVT8ScuzVG1jtMpTJsvPrbwUUeAKUxK7


As for the version, I thought I was only a minor version behind (9 vs 10)?

[TheDreadPirate]

The third digit is a minor version. Bug fixes and security patches only, usually. Each 10.# version is a fairly major version change for Jellyfin with new features, API changes, and dependency upgrades. For example, going from 10.9 to 10.10 comes with a major ffmpeg upgrade from 6.1 to 7.0.2. There were 4 additional 10.9.X releases (10.9.11) and we are up to 10.10.6.

But the log you shared doesn't appear to match your screenshot. In your screenshot you checked HEVC 10-bit decoding (you should also have HEVC checked) but the ffmpeg log doesn't indicate that it is hardware decoding this video. Nor does it show you have tone mapping checked (NOT VPP tone mapping).

Hey, thanks, upgrading my jellyfin image to 10.10.6 seem to have done the trick! Only thing is now every time I switch a view (i.e. going from /dashboard to /dashboard/settings) I have to do a hard refresh. I can see in the logs that my token is invalid each time

Code:

jellyfin2  | [22:23:11] [INF] [22] Jellyfin.Api.Auth.CustomAuthenticationHandler: CustomAuthentication was not authenticated. Failure message: Invalid token.
jellyfin2  | [22:23:11] [INF] [22] Jellyfin.Api.Auth.CustomAuthenticationHandler: AuthenticationScheme: CustomAuthentication was challenged.

I doubt this is related to the transcoding I've issues but is it possible it is a known issue with this version?

You probably need to clear your browser cache and you may need to purge old tokens in Dashboard > Devices. This will likely force you to log back in, creating a new token.
