Jellyfin’s Roku App Gains Dolby Vision and HDR10+ Support in Major Update

Jellyfin, the open-source media server, has received a significant update for Roku devices, bringing full support for advanced High Dynamic Range (HDR) video formats. Version 3.1.6 of the Jellyfin Roku app, released on March 2nd, 2026, now supports Dolby Vision, HDR10, HDR10+, and HLG, eliminating the need for transcoding in many cases and ensuring a richer viewing experience. How-To Geek and XDA Developers both reported on the update.

HDR Playback Improvements

Previously, playing HDR content on Jellyfin for Roku often resulted in videos being transcoded or failing to activate the correct HDR modes. This meant a loss of picture quality or an inability to experience the full benefits of HDR. The latest update addresses these issues by enabling direct playback of HDR files without transcoding, preserving the intended HDR experience. The developers tested the update on several Roku devices and confirmed that videos previously requiring transcoding, including HDR10+ HEVC and Dolby Vision clips, now play directly.

Anamorphic Video Support

In addition to HDR enhancements, Jellyfin v3.1.6 introduces support for anamorphic video – videos with non-square pixels. This feature is disabled by default and primarily benefits users with older recordings from cameras like HDV camcorders. How-To Geek notes that most Jellyfin users likely won’t need this feature.

User Interface and Bug Fixes

The update also includes several user interface (UI) refinements and bug fixes. Improvements have been made to the back-button logic from the home screen, the “View All” function on the “Next Up” page, and the playback info popup. Several bugs have been resolved, including issues with lazy-loading in the library, multi-line subtitles extending off-screen, and padding in the chapter list menu. The update addresses common crash causes related to the TV series screen, movie detail screen, and film metadata. XDA Developers details these improvements.

Compatibility

The Jellyfin for Roku v3.1.6 update requires Jellyfin server version 10.9 or higher to function correctly.

Ongoing Issues

As of April 10, 2024, some users reported issues with Dolby Vision DirectPlay on Roku, specifically a green/purple hue indicating HDR wasn’t properly supported, despite having compatible hardware and settings. Jellyfin Forum users have been discussing potential causes related to pixel format and video level.
