Comment 1 Paul Tannington 2024-03-15 10:43:28 UTC

Just found this bug report:

https://bugs.kde.org/show_bug.cgi?id=481979

indicating the same issue with "KDE NEON"

In the first comment (from "Patrick Silva") it is suggested this is due to a packaging issue.

you can install phonon-vlc-qt6 manually to fix your issue

Installing "phonon-vlc-qt6" is going to pull in vlc itself, together with all of vlc's dependencies...

Looking at an older (20240303) TW install on another machine it appears to be using "phonon4qt5-backend-gstreamer" - is there not a qt6 variant of that? as I don't really want vlc installed.

no, the gstreamer backend is gone.

Ah! OK.

That is, though, rather unfortunate.

So, dolphin now in effect, depends upon vlc if one wants audio/video in the preview panel.

See https://bugzilla.suse.com/show_bug.cgi?id=1219416 on the same topic.

vlc itself isn't used, but we need the plugins provided by the package.
