Description Guillaume 2025-03-15 22:38:24 UTC 
SUMMARY
When viewing video files in Dolphin, thumbnails are broken. Tested with OpenSUSE SlowRoll and Fedora 41. The Flatpak version works (but seems abandonned) if that helps... When running Dolphin through the console, I get the following errors when hovering over a video file.
> [swscaler @ 0x557cca67cf40] bad src image pointers
> kf.kio.core.connection: Socket not connected QLocalSocket::PeerClosedError
> kf.kio.core: An error occurred during write. The worker terminates now.
> QThreadStorage: Thread 0x557cc9564010 exited after QThreadStorage 2 destroyed
> QThreadStorage: Thread 0x557cc9564010 exited after QThreadStorage 1 destroyed

STEPS TO REPRODUCE
1. Open Dolphin
2. Navigate to a folder containing video files

OBSERVED RESULT
When hovering over video files the thumbnails are scrambled. Side panel video preview is blank.

EXPECTED RESULT
Video thumbnails should be displayed and cycle through video preview when hovered. The side panel should allow to play the video preview.
