Posting this in case it helps someone with the issue I was facing with my Fire Stick 4k Max client. The issue is described in detail here: https://github.com/jellyfin/jellyfin-and...ssues/2630
I found that limiting the bit rate forced JellyFin to transcode the video and remove the Dolby Vision (using server side ToneMapping). This is only really an option if you have hardware transcoding. The problem is that the max bitrate setting was arbitrary and would force a transcode of non-DV files as well.
So I created a fix which makes a few assumptions, but works for me. It relies on (and incorporates) the HDR metadata fix described here: https://forum.jellyfin.org/t-hdr-info-pa...3#pid13013
The PR is here: https://github.com/jellyfin/jellyfin-kodi/pull/807
There is a new setting under Playback -> Transcoding -> Force DolbyVision Transcode.
Simply forcing transcode was not enough - so it also transcodes to h264.
I'm not sure if DV profiles exist for h264 files, so this may not work in that case. It will probably only work for h265/hevc files.
