HDR Problem

[ototos]

Plex may have support without hardware acceleration. Jellyfin is not plex. You can always use Plex if it meets your needs. That's fine.

Jellyfin does not have tonemapping support without hardware acceleration.

in the plex settings I have hardware acceleration active, but there it is more generic, just one click is enough.
On Jellyfin you have to make a choice...

For this reason I opened a post where the problems should be reported.
Jellyfin isn't perfect and I know that.... but we're here to report everything, and to make sure that the developers also know what they have to do, otherwise it's a project that dies and it's sad.
