      @Alien I don't use Ubuntu, but on my Debian machines over the last couple of years I've noticed on one or more versions of Qt that the video hasn't worked because it was (I think, from some console messages) expecting a different version of gstreamer to what the OS had (or actually what happened was there'd be audio but no video visible). I didn't care that much because I just use Linux for development but don't release on it (and the video wasn't a major part of the app), so can't remember much more than that. Might be worth looking at what gstreamer version(s) you have and checking what Qt is expecting to find.
