Desktop Effects

SUMMARY

Some effects in "Workspace Behavior" > "Desktop Effects" section of "System Settings" have a "Show/Hide Video" button, that appears on mouse hover. When you click this button, the effect expands/collapses. So, the expanded effect has a huge height, while it doesn't contain any additional content (I guess there should be a video with a preview of the effect).

STEPS TO REPRODUCE

1. Open "System Settings"
2. Go to "Workspace Behavior" > "Desktop Effects"
3. Hover over any effect (e.g. "Looking Glass"); a "Show/Hide Video" button appears
4. Click this button

There should indeed be a video preview effect that shows up in that space. And while it's loading, there should be a progress spinner in its place to show you that something's happening. I see that in the KCM on my machine (built from source on top of openSUSE Tumbleweed).

I gather that's not what you're seeing. Do you recall it ever working, or is this a regression in Plasma 5.20?
Comment 2 popov895 2020-10-16 17:23:18 UTC
I don't know if it has worked before, as I figured out that items can be expanded already in the Plasma 5.20. Just checked that openSUSE Tumbleweed shows a play button in that place (ffmpeg is not installed) but Neon shows nothing. Same on live image.
Comment 3 Nate Graham 2020-10-16 19:56:56 UTC
Huh. Taking a look at the code, if you don't see the loading indicator at all, that means that the video isn't loading. I wonder if this is a neon packaging bug then.

Can you see if you can file the video/multimedia related package in Neon that makes this feature work by installing it?
Comment 4 popov895 2020-10-16 21:18:52 UTC
Installing package "gstreamer1.0-plugins-good" fixes the issue for me
Comment 5 Nate Graham 2020-10-16 21:32:41 UTC

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
