Freeze when jumping timeline on web browser

[Chaperone]

Hello,

I have a Docker installation of Jellyfin using a dockercompose.yml:

Code:

version: "3.9"
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    environment:
      TZ: Europe/Madrid
    group_add:
      - "937"
    volumes:
      - /local_vol/docker/jellyfin/config:/config:rw
      - /local_vol/docker/jellyfin/cache:/cache:rw
      - /local_vol/video:/media:rw
      - /local_vol/music:/music:rw
    devices:
      - /dev/dri/:/dev/dri/
    restart: unless-stopped
    network_mode: bridge
    ports:
      - 8096:8096

I have the installed server:

Code:

Server version
10.10.3
Web version
10.10.3
Build version
10.10.3

My hardware is:

• Synology NAS, DS 216+II
  
• CPU INTEL Celeron N3060
  
• RAM 8192 MB
  
• DSM Version: DSM 7.2.2-72806 Update 2
  

As an example, the information of the video I am trying to reproduce:

Code:

When I reproduce a movie from the start, works fine.
But when I try to jump along the timeline, the video or:

• Freezes and eventually continue the playback at that time
  
• Crashes the player and stops the playback
  

This process of moving the cursor along the timeline does not work:

• Edge: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36 Edg/131.0.0.0
  
• Firefox: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:133.0) Gecko/20100101 Firefox/133.0
  
• Chromium: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36
  
• Apple iPhone: using iOS 18.2, using the Jellyfin app, https://apps.apple.com/us/app/jellyfin-m...orm=iphone
  
• Samsung Tizen, using https://github.com/Georift/install-jellyfin-tizen
  

I tried with transcoding set to:

• Video Acceleration API (VAAPI), to /dev/dri/renderD128
  
• None
  

In both cases, it does not work. I am not able to jump the timeline.

This process of moving the cursor along the timeline works fine on:

• Swifting iOS
  
• Google TV
  
• Using the Windows app, https://github.com/jellyfin/jellyfin-med...ag/v1.11.1
  

Any ideas what could be wrong?
Thank you.
