Hi! I've got jellyfin running on my server in local network. It's configured with both tone mapping options, VPP and just tonemapping. I'm using the official Windows desktop client, RTX 3090 as GPU. The screen isn't capable of HDR. I'm using mpv.conf in AppData, but only for subtitles styling. Some of my movies are in HDR, so tonemapping has to happen somewhere. However, I can't find where it does happen. In the playback info, I get Direct Play and SDR video, mpv video player. The video is definitely tonemapped. The weirdness of all of it is when I disable tonemapping in the dashboard, on the server literally nothing changes, the playback info is the same, the video is still tonemapped. And to add to this, the stream quality is worse when I compare it to MPC with Madvr (no fancy upscalers there, just default cubic), this is when I began to investigate. Transcoding on the server side is definitely not happening, since it's busy doing encoding of the other movie in 4k HDR, and won't be capable of instantenous playback and seek. Any ideas what's going on, where to dig?
