SOLVED: Trickplay generation failing: Trickplay process unresponsive

[huelsenfruchtzwerg]

Since a while now (unfortunately I can't say when exactly it started), my jellyfin instance has been unable to generate trickplay images. The following appears in the logs:

I've tried both with hw encoding enabled and disabled, but the result doesn't change. I verfied during generation that the output directory is created and populated with jpgs.


I'm using the official docker container, with the following docker-compose configuration:

Code:

  jellyfin:
    image: jellyfin/jellyfin
    user: $PUID:$PGID
    devices:
      - /dev/dri:/dev/dri
    container_name: jellyfin
    network_mode: host
    environment:
      - JELLYFIN_DATA_DIR=/config/data #Uncomment for Jellyfin Images
      - JELLYFIN_CONFIG_DIR=/config #Uncomment for Jellyfin Images
      - JELLYFIN_LOG_DIR=/config/log #Uncomment for Jellyfin Images
      - JELLYFIN_CACHE_DIR=/config/cache #Uncomment for Jellyfin Images
      - TZ=$TZ
      - UMASK="022"
      - JELLYFIN_PublishedServerUrl=<snip>
    volumes:
      - ./jellyfin/config:/config
      - ./jellyfin/cache:/cache
      - $MEDIA_DIR:/media
    restart: unless-stopped

I was unfortunately unable to find any instance of this problem being discussed anywhere, so any help is appreciated.

Did you enable hardware acceleration in the trickplay settings? In your docker compose I don't see the group_add variable. If you are using hardware acceleration you need to make sure that you've properly setup the GPU passthrough, which includes passing in the group ID for the render group.

[huelsenfruchtzwerg]

The user jellyfin runs as has access to the dri device, and hardware acceleration works for normal playback.
But either way, as I mentioned in the initial post, the behaviour is the same whether I enable or disable hw acceleration for trickplay, and the log I posted is without hw acceleration.

[TheDreadPirate]

Open a bash shell for the container and manually run this command. Can you share the output via pastebin?

Code:

Good idea!

It shows a whole lot of errors:

(that's just a small excerpt, it keeps going). All the while it still keeps producing jpg thumbnails, but at some point it slows to a crawl.

That was indeed it, thank you.

How did you solve it? I have the same problem.
