Bug ID: 502302
Summary: crash in
std::default_delete<QFFmpegResampler>::operator()
Classification: Applications
Product: digikam
Version: 8.6.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Preview-Video
Assignee: digikam-bugs-n...@kde.org
Reporter: gilbertd+...@treblig.org
Target Milestone: ---
SUMMARY
I've seen a couple of digikam crashes recently, I've got a backtrace below
showing it's in std::default_delete<QFFmpegResampler>::operator()
STEPS TO REPRODUCE
(It seems to happen when some of the time)
1. Take an album with some video files among the images (not sure which format
is triggering it)
2. Open one of the images
3. Use back and forward arrows to move between the images
4. Run into one of the videos
OBSERVED RESULT
Crash as shown below
EXPECTED RESULT
No crash
