Since Plasma 6, videos aren't played anymore in gwenview. Sound is there, but screen remains black. changing the video backend from kaffeine to vlc player does not change the result Operating System: openSUSE Tumbleweed 20240423 KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 6.8.7-1-default (64-bit) Graphics Platform: X11

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0 (the latest released version)?
I can confirm that it works in the latest version again (Plasma 6.4.4, Framework 6.17.0)
