SUMMARY

The Smart Video Wallpaper Reborn has been experiencing to use MpvQt as backend to play live wallpapers recently, and it works as expected except HDR.

MPV player has had fully HDR support since v0.40.0, we can achieve it by appending "vo=dmabuf_wayland", or "vo=gpu-next" with "target-colorspace-hint=auto", however, none of these works in MpvQt, the video looks plain and washout in Smart Video Wallpaper Reborn with MpvQt plugin.

STEPS TO REPRODUCE
1. create ~/.config/mpvqt/mpvqt.conf
2. append "vo=dmabuf_wayland"
3. restart the plasma shell

OBSERVED RESULT
The video looks plane and washout.

EXPECTED RESULT
It should look like how it looks in MPV player.
