It may not be unexpected that you're not seeing any problems: in fact it would be expected if you're building from source and don't have Qt4 installed (or only the runtime or qmake points to the Qt5 install). It doesn't matter what Qt version you have, no Qt4 plugin can run in a Qt5 application (or vice-versa).

Good to know VLC 3 is in beta, btw.

Indeed. Evidently KDE prefer the VLC backend; it doesn't require installing parts of Gnome/GTk ...
