SOFTWARE/OS VERSIONS Edition Windows 10 Pro Version 22H2 Installed on 24/08/2020 OS build 19045.4957 Experience Windows Feature Experience Pack 1000.19060.1000.0 ADDITIONAL INFORMATION
Which digiKam version are you using exactly (Qt5 or Qt6)? Which graphics card are you using? I don't have my Windows computer here at the moment, under Linux there are no problems with it crashing. But it doesn't play very well under VLC either, most of the time it freezes and at the end there are graphics errors. Please test the upcoming digiKam-8.5.0 version from here: https://files.kde.org/digikam/ Maik
I am currently using 8.4.0 with Qt6. I tried the 8.5.0 you suggested but the problem persists without change. More details about my laptop: Processor: Intel(R) Core(TM) i5-5300U CPU @ 2.30GHz 2.30 GHz Graphics: Intel(R) HD Graphics 5500
The problem depends on the graphics card. I can reproduce the problem on a computer with an embedded Intel graphics card. The video runs well on a laptop with an AMD GPU. I want to test whether we can change something using environment variables. Otherwise, I would report the problem to Qt. Maik

With the current pre-release version of digiKam--8.6.0 it is possible to deactivate the hardware acceleration for video in the digiKam settings under Miscellaneous->System (restart digiKam). On my test system with Intel Graphics the sample MOV can then be played from here without crashing. I do not notice any deterioration in performance for other video files on my test system. https://files.kde.org/digikam/ Maik
@31gabig Do you seen the Maik previous comments ? Gilles Caulier
Hi, digiKam 8.5.0. is out with many fixes and improvements. https://www.digikam.org/news/2024-11-16-8.5.0_release_announcement/ This report still valid with this version? Thanks in advance Gilles Caulier
Sorry for the late reply. I just checked and the issue persists with the 8.5.0 release. It is though solved by disabling hardware acceleration in the 8.6.0 pre-release as Maik suggested. I checked on my laptop.
