The problem has never been reported before. We definitely need a backtrace.

nucleo,

What's about this file using current 8.2.0 AppImage Linux bundle ? It's
reproducible ?

Thanks in advance

Comment 5 Kenneth Soerensen 2023-11-19 15:18:05 UTC 
The issue persists with digikam-8.1.0-3.fc39.x86_64 but is not present with https://flathub.org/apps/org.kde.digikam, version 8.1.0. I have not tested with AppImage.

Git commit 79ac8d6e9cb90c8d9b456405051ec0937f8485fe by Gilles Caulier.
Committed on 26/01/2024 at 13:44.
Pushed by cgilles into branch 'master'.

Preview and Slideshow of video is now rendered with Qt6::Multimedia and Qt5::QtAVPlayer.
Older and unmaintained QtAV framework code used in digiKam core is fully removed.
Both Qt6::Multimedia and Qt5::QtAVPlayer are based and compatible to FFMpeg API 5 and later.
