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.
