Video is mostly broken for me

Hi Robbins,

Yes, there is something to experiment, at least outside digiKam, and
if all is fine, it's to replace the current internal QtAV.

Look this project in gihub:

This code is a fork more and less of QtAV with plenty of classes
dropped or replaced. It's compatible with Qt5 and Qt6. Look if this
implementation work with your video files (here it works with mine).
