How to transcode only for HDR to SDR ??

[TheDreadPirate]

Hi,

I'm new to transcoding. For years I was only allowing direct play, that wasn't a problem because all my devices support HEVC decoding. But now comes the problem of HDR. I have very few HDR screens, and most client devices playing can't do proper tonemapping / HDR2SDR like my Odroid N2+ or Raspberry Pi 4. I have a lot of movies that comes with HDR (even Dolby Vision sometimes) and that leads to washed out colors on most screens.

My server is hosted in a Docker container, running Debian on an AMD Ryzen 3 3200G CPU with iGPU.

I want to keep direct play every time it's possible. Is it possible to transcode only when the file is HDR and apply minimal modification except tonemapping / HDR to SDR ? How should I configure my transcoding settings ?

Thanks in advance for any answer.
Have a great day

Jellyfin will always direct play when possible.  If it transcodes there is a reason it did so.  Tone mapping is transcoding and it looks like your 3200G should be able to handle that?

Something like this for your transcoding options (see screenshot attached)?  Settings > Dashboard > Playback

Not sure what the quality of the transcode will be, though.
