The original crash was caused by a missing vdpau_drv_video.so.
With installed VDPAU Driver Bridge for NVidia  driver we get the following

In both cases, the crash is not in digikam but in some qtmultimedia plugin (and
is missing debug symbols, so cannot tell any more:

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...
