SOLVED: Dolby Vision Files not Reverting to HDR10 on non-Dolby Vision TV

[theguymadmax]

Code:

& "C:\Program Files\Jellyfin\Server\ffmpeg.exe" -y -hide_banner -stats -fflags +genpts+igndts -loglevel error -i "C:\path\to\dv_video.mkv" -map 0 -bsf:v hevc_metadata=remove_dovi=1 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled "C:\path\to\hdr10_video.mkv"

That's the Windows command you can run in PowerShell if Jellyfin is set in the default location. You would need to update your input and output file paths. This command makes a copy, so it's non-destructive. But once you delete the orginal, there is no getting back the DV metadata. 

As an alternative, you can also try using Kodi, which has DV/HDR compatibility features. You would either need to use Kod with Jellyfin plugin or use it as an external player for the Android TV client. I don't think we'll see HDR settings in the ATV app anytime soon.
