Ubuntu – Gwenview – phonon backend plugin could not be loaded


I have Gwenview installed in Ubuntu 16.10, and I was not able to play videos. The console output gives this error:

WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded

I had tried several options around, including the installation of phonon-backends-vlc, which did not make a difference.

Best Answer

After some tries, I have realised that there are separate packages for phonon qt5.

The installation of the following packages solved the issue on my system:

sudo apt install phonon4qt5 phonon4qt5-backend-gstreamer phonon4qt5-backend-vlc

Now, the installation of these packages should probably be recommended from the gwenview package, so this is probably a packaging bug.
