I will take a look. Sound like a wrong binary operator beween P an T
albums selection...

By displayed, you want mean preview using embeded video player ?

If yes, preview is delegate to KDE phonon component which use backend
in background to play video content (as GStreamer for ex).

Phonon is just a software component that we use in digiKam. There is
no phonon code in digiKam. We embeded widget, and pass video file url
when it's need (+ some control feedback). That all.
