SOLVED: JellyFin No Longer Direct Playing HDR Content on Roku

[bitmap]

In the future please upload the log to privatebin.net. It's hard to parse as a raw text file.

Have you tried removing the DV from the file since DV in MKV is an issue? It should fall back to HDR but that isn't happening.

A little more info about your setup (server version, install method and host OS, Roku model) would be helpful as well. I'm interested in the Jellyfin log as well, though I'm unsure whether that would provide additional information.

You can find a guide for converting DV to HDR10 here: https://forum.jellyfin.org/t-converting-...n-to-hdr10
