Comment 1 Maik Qualmann 2020-06-29 05:51:59 UTC
There is nothing at the crash point that should trigger a crash.
Can you please create a new backtrace?
Can you please post the output of "opencv_version --hw --opencl"?
Can you also test whether the problem with the AppImage can be reproduced?
From here:

Comment 2 Maik Qualmann 2020-06-29 06:04:17 UTC
My guess is that the crash in OpenCV is triggered by OpenCL hardware acceleration. You are using AMD hardware. OpenCV has an environment variable to disable OpenCL.

Comment 3 Thomas Coquelin 2020-07-02 21:38:48 UTC
Hello,
I tried digikam with OPENCV_OPENCL_RUNTIME=disabled and OPENCV_OPENCL_DEVICE=null env, face detection scan works to the end.
I'll try to run some opencv opencl tests.

Hi,

Can you check if this crash still exist with last weekly AppImage build
available here :

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

Thanks in advance

We need a fresh feedback on this file using this version.

Thanks in advance
