Bug ID: 513785
Summary: Feature: Implement wayland staging protocols
ext_image_copy_capture_v1 and
ext_image_capture_source_v1
Classification: Plasma
Product: kwin
Version First unspecified
Reported In:
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
wayland-protocols merged[3] the protocols ext_image_copy_capture_v1[1] and
ext_image_capture_source_v1[2] into staging in august of 2024.
There represent an improved version of wlr-screencopy-unstable-v1, which is
quite widespread. It has the advantage, to many, that it does not use XDG
Portals, which means its far more useful for commandline usage, called from a
global hotkey, or other kinds of usecase where having to accept a portal every
time would be disruptive. I dont know KDEs stance on Portals and explicit
permissions, but it should still be possible to implement a permission system
for this (afaik thats what Hyprland is planning/doing).
Its currently implemented in the following compositors:
- COSMIC
- mahkoh/jay
- canonical/Mir
- wlroots
- Sway
- linuxdeepin/treeland
- Labwc
- Wayfire
With the following having plans to implement it:
- Hyprland [4]
- Niri [5]
Tools that can use the protocols already:
- emersion/grim - popular commandline screenshotter, feels like 80% of posts
i've come across asking for wlr-screencopy-unstable-v1 support are grim users
- Ferdi265/wl-mirror - a simple Wayland output mirror client
- russelltg/wl-screenrec - High performance screen recorder for wlroots Wayland
- whynothugo/shotman - The uncompromising screenshot GUI for Wayland
compositors
- any1/wayvnc - a VNC server for wlroots-based Wayland compositors
Note: The applications i mention above likely won't magically work if KWin gets
this protocol, but for many it would become a far more reasonable ask to
support KWin.
