Thank you for taking the time to test this. My environment is Ubuntu 24.04.5 LTS, and I can confirm that the issue does not occur with Qt 6.8.3 either. (The application ran for more than five minutes without freezing.) In my environment, sound also works with Qt 6.12.0, but the application eventually freezes and produces a large number of error messages. The FFmpeg versions used by Qt Multimedia are the same in my environment as well: Qt 6.8.3 Using Qt multimedia with FFmpeg version 7.1 LGPL version 2.1 or later Qt 6.12.0 Using Qt multimedia with FFmpeg version 9.0.1 LGPL version 2.1 or later It's interesting that different issues seem to occur depending on the Ubuntu version.

yep. really cool. will try later ... curious: years ago, as I switched from BlackBerry10 (Cascades/Qt 4.8) to Qt 5 (QuickControls2) I really missed the GroupDataModel from Cascades, where I could do things like this: import bb.cascades 1.2 ListView { dataModel: GroupDataModel { sortingKeys: ["lastName", "firstName"] sortedAscending: true grouping: ItemGrouping.ByFirstChar } } great to see what's now possible with Qt QML - THX :)

Thanks a lot for all this information. It has helped me get clarity on the questions that have been bugging me for weeks. I can now decide better what I want to do, and why. I will definitely share these with them ideas about unifying the UI for mobile and desktop with Qt, as it seems like it doesn't necessarily warrant replacing starting their application from scratch, only their UI code will get replaced (and its bindings).

This had been reported to Squish technical support team, and closed on behalf of the reporter. Unfortunately it was not possible to identify a clear cause so far.
