HDR config question
Today, I heard some people say that we had been able to watch HDR contents via DRM, so I tried it, and it really did. but there are some questions.
- Does target-colorspace-hint affect SDR contents in Gnome Desktop Environment?
- The color looks so strange when my ICC profile is enabled, does that mean we can't enable both at the same time? It looks much more saturate with icc-profile, the dark area looks darker, the bright area looks brighter.
- Will there be a way to enable interpolation while watching HDR movies?

I have no clue. But I strongly doubt it.

The ICC profile will have to be constructed against a PQ target curve to work properly. You cannot combine an SDR ICC profile with HDR output mode.

It should already work. I'm not sure what you mean?
@haasn I don't see the --video-sync=display-resample work when I play HDR movies in TTY, doesn't --interpolation need --video-sync=display-resample to be enabled?

Here is how I watch the HDR movies in TTY:
mpv --vo=gpu-next --gpu-api=vulkan --gpu-context=displayvk --target-colorspace-hint <video>
display-resample doesn't work for me when using displayvk either, so it might be a limitation of displayvk (or a bug). As a workaround, you can use gamescope's embedded mode (from a TTY) with vulkan-context set to x11vk. And it also supports HDR, although I'm not sure of the full requirements compared to HDR gaming. I suspect an AMD card will be required at the least.
