What it is exactly that Dolphin uses to play videos inside the information panel?

I’m just trying to figure out if I can fix by myself the video previews that stopped working on Tumbleweed. Seems like there was some sort of recent carfuffle involving open-h264 packages that may be related, but I don’t know what Dolphin actually uses.

What it is and how?

On arch dolphin uses the “phonon-qt6-vlc / mpv / gstreamer” packages to achieve this functionality, I don’t know about suse

Hum… maybe the problem is because I removed VLC?
Will test this when I get home.

There’s also this [1] reported over at endeavouros forums. (Endeavouros is (almost) arch. )

[1] Phonon-qt6-mpv removed from the repos - #17 by dirn - Important notifications - EndeavourOS

I’m on fedora 42 and

dnf install phonon-backend-gstreamer 

fixed playing videos in dolphin. I suspect I uninstalled it when I removed the bundled video player after installation. I don’t really need it but it’s good to have it working

That was really it.
After installing Tumbleweed I removed some “fat” and this was probably removed along with VLC.

FYI, next dolphin (25.08) release will use qmultimedia instead of phonon, but still gstreamer on the backend.

It should be a more common dependency with less chances of it missing.

fantastic. I’m a big fan of under the hood modernisation. my problem came from not paying attention to the list of things getting removed when uninstsalling an RPM, and then forgetting I did it.
