The ext-image-capture-source-v1 and ext-image-copy-capture-v1 screen copy protocols build upon wlroots' wlr-screencopy-unstable-v1 with various improvements for better screen capture support under Wayland. These new protocols should allow for better performance and window capturing support for use-cases around RDP/VNC remote desktop, screen sharing, and more.

under the definition of bike shedding in the Encyclopedia you'll find wayland the prime example. been waiting years on one pr for them to decide on the word "may" vs "will"

It drives me crazy. Just release it 18+months ago and iterate with versions, at least your users will have the feature in their hands.

I assume they went with way land as a compromise.

I hope this can mean I can use my android tablet as a 3rd screen with vnc with usable lag and frame rate

Pipewire works well enough for sharing screen even though it isn't well supported by shit software like Slack. Would this replace it?

[-] pnutzh4x0r@lemmy.ndlug.org 11 points 3 months ago

No, most likely Pipewire would be used to implement the protocol for various compositors.

Think of the protocols as high-level descriptions of interfaces (or designs) that specify what needs to be implemented to support a particular feature (in this case capturing images of a "screen"). Looking at this one, it describes a ext_image_capture_source_v1 object that has various methods such as create_source and destroy. Different compositors could then implement or support this interface with whatever technology they wish (most will rely on Pipewire).

This is already the case with the existing screensharing protocol. For instance wlroots uses pipewire buffers in xdg-desktop-portal-wlr.

So... does THIS mean that this doesn't support explicit sync, right as explicit sync is about to be stable and supported in the NVIDIA 560/565 drivers? As far as I know there are currently other ways to do screen capture outside of this protocol on Wayland so its not like there are no interim solutions, why release this when it is essentially still incomplete?

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
