Hello,
Just for any developer finding this topic on the internet, I will update some info about this multimedia plugin.

I am working with Qt5.5.1 on Ubuntu16.04. We must read .avi videos in our project so we developed with QMediaPlayer.

After succeeding on our development computer, we tried to create a "deployment". Witch was great on Linux was that all Qt5 libs were installed by default. We verified that gstreamer0.10* was also installed.
Our software was running without issue but we broke into this error :
defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer" , and the video does not play.

The hint from @willypuzzle, installing multimedia plugins, saved my day. All is running perfectly now.
Hope this can help other people too.

Cheers, Fabien.
