Color Error When Transcoding Dolby Vision on Jellyfin

[barkerxavierr]

Hi everyone,

I'm having a pretty annoying error when playing Dolby Vision video files on Jellyfin. Specifically, when Jellyfin tries to transcode Dolby Vision video for playback on a non-supported device (e.g. a web browser or a regular TV), the transcoded video has serious color errors: human skin turns purple or moss green, the entire scene has a red or purple tint, making the video almost unwatchable.

I'm using Jellyfin version 10.9.1 on Windows 10, Intel CPU with iGPU (QuickSync enabled), the video file is .mkv with HEVC Main10 + Dolby Vision (dvhe.05.06). I've tried transcoding with both software and hardware, but the result is the same color error.

I suspect that Jellyfin is not handling Dolby Vision to SDR transcoding well or is not removing metadata properly when decoding. Has anyone fixed this or have a workaround that works?

Prefer DXVA or system native decoder is required for dolby vision transcoding support.
