I use Jellyfin heavily, and it's a fantastic project, but I really wish they would address the issues with transcoding, specifically the ability to force it on.

My library contains a decent amount of HDR (lots of DV) content. On my TVs (using Nvidia Shield), it will direct play the DV content, resulting in a green picture. If I turn on burned-in subtitles or drop the bitrate and FORCE it to transcode, it's looks perfect. I've resorted to just setting a low bitrate on clients so it always transcodes.

I'm really hoping a future version gives us the ability to set more fine-grained transcoding settings per-client. Even the ability to disable direct-play completely would be fantastic.
