Screencasting does not work with spectacle, it doesn't matter what
format you choose, it won't work.
Journalctl results in 'Failed to export video: Temporary file URL must
be an existing local file'. The same error message is produced on the
GUI as soon as you terminate the video recording. kde-plasma-desktop
was installed in an attempt to install KDE on a fresh Debian trixie
install.

Coincidentally, even the thumbnails preview in taskbar is not working
-- the root cause maybe the same, because both use pipewire.

Both of these features work with KDE neon live CDs suggesting a
package build configuration issue.

Hint -- This is seconded by the fact that I've been facing similar
issues on Gentoo (where the build configuration is equivalent to USE
configuration) where screencasting and thumbnail preview is not
working only for my setup. There are plenty of Gentoo users for whom
it's working, each of whom have different build configuration.

Dear dE,

there were fixes in the latest version of the package including commits I backported from the Plasma 6.4 branch that improved the video recording specifically.

So could you confirm whether you still have the issue or if it was fixed in the mean time ?


Thanks,
