Jellyfin hub
Jellyfin beginner guides that fix the real problems.
Start with a simple Jellyfin server, then work through folders, mounts, Docker paths, USB storage, subtitles, Direct Play, transcoding, client devices, and safe remote access.
If you are new
Follow this order
- Install Jellyfin on a simple low-power server.
- Put media in stable folders and mounts.
- Fix Linux or Docker permissions properly.
- Check playback mode before buying hardware.
- Use private remote access before exposing anything publicly.
Storage fix path
Media missing after reboot?
Verify the disk mount, UUID, fstab entry, service timing, and Jellyfin access before rescanning or reinstalling anything.
Open the reboot and mount guide → Playback fix path
Unexpected transcoding?
Read the dashboard reason, test subtitles and audio, compare clients, and inspect the file before changing the server.
Open the transcoding diagnosis guide → Recent changes
Jellyfin updates
Release and compatibility changes that may affect your server, clients, or playback.
View all Jellyfin updates → Jellyfin 10.11.7 fixed important security issues, 10.11.11 is now the stable patch, and the next major server release is 12.0 rather than 10.12.
Jellyfin for Android 2.7 changes downloads, makes the native player the default, improves Android Auto, and ends future app updates for Android 5 devices.
Upgrade safely
Keep Jellyfin 10.11 current and prepare safely for version 12
Apply the latest stable 10.11 patch first, then prepare backups, plugins, remote access and rollback for Jellyfin 12.
Update Jellyfin 10.11 safely on Ubuntu or Docker: check the current version, take an offline backup, review plugins, update one layer and verify playback.
Read guide → Prepare a Jellyfin 10.10 or 10.11 server for Jellyfin 12. Check your version, create a restorable backup, audit plugins and plan the first startup safely.

Solve missing media, empty libraries, mounts, and Docker paths
Most beginner Jellyfin problems are path, mount, folder permission, new-file inheritance, USB storage, or Docker volume mapping problems.
Fix Jellyfin when newly added movies or episodes do not appear. Check new-file permissions, mounts, Docker paths, scans, monitoring, naming and logs.
Read guide → Fix a Jellyfin library that is empty or missing media. Check mounts, Linux permissions, Docker paths, library folders, naming, scans and logs in the correct order.
Read guide → 
Fix Jellyfin libraries that disappear after reboot. Check mount points, UUID entries, fstab, service timing, permissions, and empty media folders.

Read guide → Playback
Reduce transcoding and improve Direct Play
Understand playback modes, subtitle burn-in, formats, client compatibility, and what hardware actually matters.
Compare Jellyfin Direct Play, Direct Stream and transcoding. See CPU use, quality differences, common triggers and how to check the active playback mode.
