HDR playback (passthrough metadata to display) possible

[Klaus1189]

Hey guys,
How do I setup mpv to play HDR video files? -> I want to passthrough HDR metadata to TV.

So I can then decide if I want tonemapping in mpv or let my diplay do the tonemapping.

Do I need to enable HDR in windows before playback?
I would like to have an automatic toggle when starting a HDR file like madVR does.

I have Nvidia GPU

In Kodi my TV displays an OSD info that HDR metadata is received, but I can not get mpv to do this. But I want mpv.

Please help me :)

Have you tried --target-colorspace-hint?

[Klaus1189]

Yes. But do I know if mpv reads this command in my conf file?

[Klaus1189]

I am sure I am doing something wrong. Do I need to install mpv for this feature? I use portable mode for now.

For me, it will only automatically enable HDR in windows if using --gpu-api=d3d11, otherwise HDR has to be turned on in Windows first.

colors are different with "--gpu-api=d3d11" but still no HDR OSD info of the TV.

Please help me :(

Any other advices?

There's no signaling. Your TV won't tell you that it's HDR.

huh? There is signaling.

My TV has never notified me that it is HDR, when using mpv.

There are people we use it on daily basis, it works.

--target-colorspace-hint may work better with --vo=gpu-next --gpu-api=d3d11, can also try --gpu-api=vulkan, but d3d11 should work better. Go fullscreen and Windows should passthrough HDR metadata to your display.

I am using mpv and Windows, with --target-colorspace-hint and --vo=gpu-next --gpu-api=d3d11 = I have to enable HDR on Windows settings.

If I use --gpu-api=vulkan it will auto-enable HDR on Windows settings.

[Klaus1189]

The OSD message I want is also displayed of the TV when enabling the HDR switch in windows.
I want autoswitch to HDR without the need for me to enable HDR in windows.

Auto-Switch to HDR on Windows = --gpu-api=vulkan
Manually Switch to HDR on Windows = --gpu-api=d3d11
Look at the comment I linked above to see further explanation.
