Mostly for the fun of it. I wanted to experiment a bit. If I was to 
publish the flatpak, I would bundle QT, but I was excited, to see it 
working that well :)
On the other hand, if I was to set up a repository with more packages 
using QT, I would probably build a runtime..?

Okay, that makes sense. I didn't get that right. The files are there, 
but gst-inspect does not list the plugins and VLC can't play mp4 files 
and others. Seems like gstreamer doesn't look into the app/lib folder 
for extensions. I'll look into this.
