Description Thomas N. 2024-04-18 11:21:00 UTC

SUMMARY
Playback of any video files within Gwenview is broken in X11 session since transition to KF6 / Plasma 6. Sound is playing correctly, time in progress bar is advancing, but playback window is black (only background color, no video).
Video thumbnails are shown correctly in file browser. Pictures are also shown correctly.
Video playback works as expected in Wayland session.

STEPS TO REPRODUCE
1. Open Gwenview from within X11 session
2. Select any supported video file for playback

OBSERVED RESULT
Black screen (background color) where video should be visible, audio works

EXPECTED RESULT
Video and audio should be working.

Adding the x11-only keyword

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?

If yes, are you sure that it is not a dependency issue (sounds like a classic ffmpeg problem).
