Comment 1 caulier.gilles 2017-06-15 11:15:15 UTC
It crash in video thumbnailer, not in fingerprint code.

After 5.3.0, we have rewrite all the video support in digiKam using QtAV instead QtMultmedia.

I'm sure that crash will disapear with digiKam 5.6.0 just released. Please test with Linux AppImage bundle available here :

Comment 2 caulier.gilles 2017-06-22 21:43:12 UTC
digiKam 5.6.0 is now released and available as bundle for Linux, MacOS and Windows.

https://www.digikam.org/news/2017-06-21-5.6.0-release-announcement/

Can you check if problem still exists with this version ?

Thanks in advance

Comment 3 caulier.gilles 2017-07-23 18:27:32 UTC
New digiKam 5.7.0 are built with current implementation as pre-release bundles:

Problem still reproducible ?

Following this commit:

https://commits.kde.org/digikam/6a9fd9891a3ff341dc42fe36158cbf0101d513b6

... the approach to fix this problem is under way and new digiKam 5.8.0 pre-release bundles will be compiled tonight to lets a chance to end-users to give a feedback about this fix before the 5.8.0 official release planed before Christmas 2017.

The bundles will be available in 2 hours at this url:

https://files.kde.org/digikam/

Please do not waste time to test if this file is always valid for next 5.8.0.

Thanks in advance

Comment 6 Maik Qualmann 2018-03-29 19:30:09 UTC
We now have a FFmpeg-based video thumbnailer. The code leading to crash no longer exists. I close the bug.
