HDR video playback - ArchWiki

Jump to content

HDR support on Linux is not implemented yet in the display servers, though it is being worked on:

- X.org (and Xorg clients): no support for passing HDR metadata to the display, see https://gitlab.freedesktop.org/xorg/xserver/-/issues/1037#note_521100

- Wayland (and Wayland clients): no support for passing HDR metadata to the display, see https://gitlab.freedesktop.org/wayland/weston/-/issues/467 and https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14

- DRM clients can directly pass HDR metadata, but this is not available from regular userspace clients, only specialized software can use it: https://gitlab.freedesktop.org/mesa/drm/-/blob/main/include/drm/drm_mode.h#L809
