How can I avoid Dolby Vision transcoding in webOS? - el_Pedr0 - 2025-09-21
I want to play Dolby Vision 5 and 8 mkv files on my webOS LG TV without transcoding. However I have tried a number of Dolby Vision files and all end up transcoding, which my non hardware accellerated hardware can't handle.
I have read that it should be possible (JellyfinForum GitHub Reddit). I have failed to find a comprehensive guide and some of the information I've come across talks about GUI configuration options which I don't see, so might relate to a version or environment that does not match mine.
Example video: 4K HEVC Dolby Vision Profile 8.1 (HDR10)

Any advice on how I can get DV files to play without transcoding would be welcome.
Environment:
Client: LG OLED55B7V WebOS 06.10.65 (rooted)
Jellyfin server: 10.10.7
OS: Ubuntu 24.04.3 LTS (in LXC running on Proxmox)
Jellyfin webOS client: 1.2.2 (via LG content store)
FFMPEG: /usr/lib/jellyfin-ffmpeg/ffmpeg -version -> ffmpeg version 7.1.1-Jellyfin Copyright © 2000-2025 the FFmpeg developers
NB: In my browser, clicking on the links below yields an error message, but right clicking and open in new tab works.

I still can't get it to work despite confirmation that it should work here on the forum: https://forum.jellyfin.org/t-how-to-get-dolbyvision-on-webos?pid=46587#pid46587.
