HI Maik,

The video slide show tool is the last part of digiKam which depend of qtav API,
when we switch definitively to Qt6.

QtMultimedia version 6 do not allows to encode frame by frame from Image. Qt6
API have this kind of feature, but this have been dropped in Qt6. I see a
report in Qt bugzilla about missing API, but Qt team report that it's not a
priority to restore the ful API in Qt6.

So, we needs to found a C++ API based on ffmpeg to do the job in-place of QtAv.
Also, the current implementation do not allow to set audio track on the video.

I found this interesting project on github :

https://github.com/apc-llc/moviemaker-cpp

I use also Numa and GTK3 API, but i'm sure that we can drop this in favor to Qt
API.
