HDR playback is not supported.

[Weather-OS]

Overview Description:
Whilst this project uses the MPV project as it's video player backend, it doesn't support HDR playback.

Steps to Reproduce:

1. Add the options --vo=gpu-next --target-colorspace-hint=yes --gpu-api=vulkan --gpu-context=waylandvk as you normally would in MPV inside "Extra MPV Options".
2. Play an HDR video.

Actual Results:
HDR doesn't get activated.

Expected Results:
HDR should get detected and activated.

Version: 0.27-1

I don't think GTK supports HDR at the moment, and it would have to be landed there before we'll be able to implement it.

Looks like it's shipping in 4.16. Any plans on implementing it?

Sure, but I would wait until it's actually released.

It's out.

So what's the status of this issue now that there seems to be nothing blocking hdr on celluloid?

[gnome-mpv]

It still needs to be implemented.
