Jellyfin Project Website and Documentation

Version 0.5.0 introduces several major improvements for the Kodi ecosystem:

• Kodi 19 (Matrix) Support: Full compatibility with Kodi 19, which includes support for Python 3.
• Faster Library Sync: Significant speed increases during the initial library synchronization, with some sync times reduced by more than 50%.
• Improved Logging: Reduced log noise for better performance and easier debugging.

Jellyfin 10.9.0 introduces several significant features:

• Trickplay: Supports live video scrubbing with live previews (requires client support).
• Image Formats: Support for AVIF and WEBP in Pictures libraries.
• Search: Tags are now included in search results.
• Subtitles: Support for multiple simultaneous subtitle tracks (up to two: primary and secondary) in the web player, and support for hearing-impaired subtitles (sdh/hi./cc).
• Music: Improved MusicBrainz interface and support for local lyric files (embedded or external).
• Transcoding: Support for AV1 hardware/software encoding, RK3588 hardware acceleration via MPP, Vulkan-based tonemapping with AMD VA-API, and complete hardware acceleration for Apple systems (Silicon and Intel).

The Jellyfin website has migrated to a unified repository structure and is built using Docusaurus. This consolidation integrates the blog, documentation, and the main website into a single repository (jellyfin/jellyfin.org), replacing the previous separate repositories (jellyfin-blog, jellyfin-docs, and jellyfin.github.io).

If you are looking for documentation or blog posts, ensure you are contributing to or searching within the jellyfin/jellyfin.org repository, as the older repositories are being archived.

Jellyfin supports most common video formats, including mp4 and mkv. For movie and music video libraries, Jellyfin can also process VIDEO_TS and BDMV folder structures.

Limitations of folder structures: Using VIDEO_TS or BDMV folders does not support:

• Multiple versions of the same media
• Multiple parts
• External subtitle tracks
• External audio tracks

Disc Images: While .iso and other disc image formats may work, they are not officially supported. For the best experience, it is recommended to either:

1. Remux disc images into mkv containers.
2. Extract them into VIDEO_TS or BDMV folders.

Jellyfin retrieves media metadata from several default sources and can be extended with additional providers.

Default Providers:

• The Movie Database (TMDb)
• The Open Movie Database API (OMDb API) (Note: OMDb API only provides English metadata)
• Local .nfo files

Official Plugin Providers: You can install additional official providers via the Plugin Catalog, including:

• TheTVDB
• fanart.tv
• AniDB

Custom Providers: Developers can create their own metadata providers using the Jellyfin Plugin API.

The Jellyfin 10.6.0 web client includes several user-facing improvements:

• Ebook Support: Added an EPUB reader based on epub.js.
• Music Experience: Redesigned mobile music player interface, including the mini player and remote player UI.
• Image Loading: Reworked image loading system that unloads out-of-view images to improve memory usage, and added Blurhash placeholder support.
• Subtitle Rendering: Improved performance for SSA/ASS subtitles with heavy effects.
• Library Configuration: Added a configuration option to set the number of items per page in libraries.
• Plugin Support: Added support for multiple plugin repositories.
• Chromecast: Added a toggle for the nightly version of the Chromecast client.

You can "chain" CSS selectors together by separating them with commas. This allows you to apply the same styling rules to multiple different elements simultaneously, which is useful for maintaining consistency in UI tweaks like border colors or font sizes.

.emby-input,
.emby-textarea,
.emby-select {
  border-color: #d00000;
}

There are two distinct Kodi add-ons for Jellyfin, each serving different use cases:

• Jellyfin for Kodi: Syncs metadata from Jellyfin libraries directly into the local Kodi database. This makes media appear as native Kodi content (e.g., under Movies/TV Shows on the home screen) with virtually no browsing delay. However, it consumes the Kodi database and can cause conflicts if you use other local media or external database managers. It requires a sync process on startup or while running.
• JellyCon: Functions as a standard streaming add-on. Media is accessed via the Add-ons -> JellyCon menu. It is better for switching between multiple Jellyfin servers or users because it does not rely on local metadata syncing. Browsing may have a slight delay (1-2 seconds) as it requests info from the server on demand, but there is no database sync overhead.
