digiKam 5.4.0 bundles will use QtAV framework instead Qt5Multimedia to thumb
and play video. 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...

The screenshot here :

... is based on pre-release of AppImage 64 bits Linux bundle, just recompiled
and post to GDrive for testing.
