SOLVED: DV file / HDR issues on supported device

[TheDreadPirate]

See my post before theguymadmax about some things to try to get HDR to work on your setups.

But to madmax's point, that this isn't a bug. Your device/hardware might support it, but the software player might not. Or it might only support it in a particular container. Or it might only support it in Windows but not Linux or vice versa. Or it might only support particular DoVi profiles. Or it will support it but only if you configure things in a particular way.

Like I stated earlier: DoVi compatibility is a mess.

Also, tone mapping, is the process of converting HDR to SDR. When Jellyfin transcodes will always convert HDR to SDR with or without tone mapping. With tone mapping the colors will be correct. Without tone mapping it will be washed out. Though, work is ongoing to enable HDR to HDR transcoding (no ETA).

Tone mapping is a fall back when there isn't a path to direct play the HDR content for whatever reason.
