mpv outputs PQ/BT.2020 regardless of source content when HDR swapchain is active. Signal this output colorspace to Wayland instead of the source colorspace.
Pass pause=no option to loadfile command. Without this, mpv keeps the previous pause state which causes subsequent files to stay paused.
Fixes WebEngine overlay alpha blending (OSD fade) over mpv video. Qt Vulkan caused crashes on Radeon GPUs and broke transparency. - Remove QVulkanInstance and setGraphicsApi(Vulkan) for Qt - Add alpha buffer to surface format for subsurface blending - mpv subsurface retains its own Vulkan instance for HDR
When the window resizes, immediately render a frame with the new swapchain dimensions instead of waiting for mpv's update signal. Fixes subsurface not resizing when video is paused.

Hacked-together, but provides functioning HDR playback on Plasma Wayland (Arch Linux). This likely will not be merged for quite a while. It relies upon non-upstream changes to mpv [1] [2].
Compile with:
Partially resolves (Wayland only) https://github.com/jellyfin/jellyfin-desktop/issues/362, https://github.com/jellyfin/jellyfin-desktop/issues/523
Tested on:
Appears visually identical to standalone mpv running with this config:
