Bug 494453

The same.
I don't have too much debug info, but this what I see in console:
```
$ spectacle

This seems relevant. The screencast protocol fails to initialize

*** Bug 494443 has been marked as a duplicate of this bug. ***

The problem is that Neon's pipewire package is too old for screencast support in KWin.

Please update your Neon to the newly release 24.04 base where it will work

Pipewire version is 1.0.7-3~ubuntu22.04.

I unfortunately can't because the software I need for work, HP Anyware, doesn't support 24.04 yet.

$ apt list pipewire
Listing... Done
pipewire/tuxedo,now 1.2.0-1tux1 amd64 [installed,automatic]

This is my Pipewire using the one from Tuxedo's repo

I'm seeing this same problem (also using the 22.04-base Neon release).

The main issue this is causing me is I'm getting this same error when trying to screen share in MS Edge browser:
"Remember requesting the interface on your desktop file: X-KDE-Wayland-Interfaces=zkde_screencast_unstable_v1" 

We need to use MS Edge Browser for work, and our work distro is based on Ubuntu 22.04, so I can't yet upgrade to 24.04./

Is there a way to force kwin to not use Pipewire for screencasting? It worked fine in Plasma 6.1, but broke when upgraded to Plasma 6.2, and screensharing worked fine in Plasma 6.1, so surely there is a mechanism to capture the screen without newer pipewire?

What I did for mine is I added Tuxedo's Plasma repo, then downgraded certain packages to 6.1.5 (i.e. kwin, Plasma).

Spectacle's working again, though I haven't had the time to test it out.

PipeWire is the only option for screen recording on Wayland, no matter which screen recorder you use.
The only way to avoid using a newer PipeWire is to use an older PipeWire.

Okay, I just updated to Neon based on 24.04, but I'm using exactly the same pipewire version that I was using on 22.04, and the screen sharing is now working. Here are the facts.

Neon-22.04, Plasma 6.1, Wayland, Pipewire 1.0.7-3  =  Screen sharing works fine
Neon-22.04, Plasma 6.2, Wayland, Pipewire 1.0.7-3  =  Screen sharing is broken as per this issue thread
Neon-24.04, Plasma 6.2, Wayland, Pipewire 1.0.7-3  =  Screen sharing is fixed.

So I haven't upgraded to newer Pipewire, using exactly the same pipewire version (from the SOURAV DAS ppa).
So with exactly the same version of Pipewire, and same version of Plasma and Kwin (with wayland), the only thing thats different is using the kwin packaged for Neon-22.04 vs the kwin packaged for Neon-24.04.

I believe this was a packaging change in Plasma 6.2 for Neon-22.04, it disables screensharing support in wayland regardless of pipewire version.

I am having the same issue `KWin Screencasting is not available.`  error. 
It used to work a few days ago, differenes are
1) Updated nvidia driver to 565 
2) Installed `apt install ffmpeg libavcodec-extra libavcodec-extra60 libavdevice60  libavfilter-extra  libavfilter-extra9 `

After that I can't record video.

Pipewire is 1.2 and Chrome, Firefox, OBS can record with pipewire, as well as vokoscreenrecorder.

I am out of ideas, anyone?

The original issue was specific to KDE neon 22.04 and appears to be fixed in the version based on 24.04; closing.

If you're not running KDE neon, please open a new bug report. Thanks!
