Similar to bug 335111. A Qt4 application loads the VLC backend, which uses a Qt5-based VLC.

Comment 2 caulier.gilles 2017-01-06 18:08:28 UTC

digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video/audio. The Slideshow tool will also support video as well.

QtAV use ffmpeg codecs. It's multi-platform and will always available in
OSX, Windows and Linux bundles that digiKam team provide.

For Linux packagers, you will need to turn on video support at compilation time
and solve QtAV dependencies...
