SUMMARY If you scan a mp4 video file encoded with av1 video and opus audio, digikam immediately crashes. It happens with WAL enabled or disabled. STEPS TO REPRODUCE 1. Add folder with av1 opus mp4 videos in configuration page 2. Exit configuration page 3. Scan automatically starts, app hangs, app exits OR 1. Perform the above steps 2. Reopen digikam 2b. If autoscan is enabled, the scan automatically starts, and the app hangs and exits 3. Go to folder with videos in thumbnail view 4. App hangs and exits DEBUGVIEW I have remove personal info from the logs, and the log starts as soon as I click on the folder to see it in the thumbnails view.

It looks like the same problem as Bug 471797 and Bug 471269 with the libaom. Can you provide a sample video of the camera? Maik

Created attachment 160470 [details] Video encoded with AV1 libaom video and OPUS audio using nmkoder
Both the aom and svt files cause a crash on thumbnail generation.
Thanks for the test videos. As with the bug reports with the AVIF images, I cannot reproduce a crash in a Windows 10 VM. Thumbnails are created and the videos can be played. I'll test it tomorrow on 2 real Windows 10 machines. There is something about libaom (compilation?) that is system dependent. Gilles, can you please create a new digiKam-8.2.0 Windows bundle with the latest change in compile flags to libaom? Maik
Hi Maik, I will do it tomorrow morning. Today I'm on the road... Gilles
Hi Maik, Build is under progress.. Note that we use currently KF5 version 5.106. In KImageFormat we can see these changes: 5.107: pcx: multiple fixes (2) Avoid unnecessary conversions RGB/SGI writer: fix alpha detection and image limit size TGA writer: fix alpha detection and performance improvements pcx: multiple fixes PCX: Fix reading of the extended palette (bug 463951) 5.108: jxl: add support for libjxl v0.9, drop support for old 0.6.1 Nothing about AOM support improvement or fix. So i'm not sure if updating KF5 will help in this file. Best Gilles
Windows build is now ready at usual place and recompiled with the new libaom configuration: https://files.kde.org/digikam/ Gilles
Here on a real Windows 10 machine with Intel Core I5, I have no problems with the sample videos or AVIF images from the other bug reports. Maik
Maik, did you check with the last Windows installer ? Gilles
Yes, I checked it with today's current Windows Installer. But we already know the problem from AVIF images that I could not reproduce a crash with libaom on any of my Windows machines. We'll have to wait and see what the bug reporters write. Maik
@lincoln@vandymail.com, This problem still reproducible with the new digiKam 8.2.0 pre-release Windows installer available at usual place: https://files.kde.org/digikam/ This new bundle is based on last Qt framework 5.15.11 and KDE framework 5.110. Thanks in advance Gilles Caulier
@Ping all... Any feedback here following my last comment #13 Thanks in advance Gilles Caulier
I'm trying right now with a folder that contains videos that crash the current version. Seems that now it works well.
Perfect, thanks for the feedback
