Description Olivier FAURAX 2015-09-23 23:04:11 CEST 
At first, VLC was not launching at all.

$ qvlc -v
VLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision 2.2.1-0-ga425c42)
[0000000000c72118] core libvlc warning: cannot load module `/usr/lib64/vlc/plugins/gui/libqt4_plugin.so' (libQt5Widgets.so.5: Ne peut ouvrir le fichier d'objet partagé: Aucun fichier ou dossier de ce type)
[0000000000d705c8] core interface error: no suitable interface module
[0000000000c72118] core libvlc error: interface "default" initialization failed

I installed lib64qt5widgets5.
Then, the same with: lib64qt5gui5 and lib64qt5core5.

The last one was tricky, since the error was :
$ vlc -v
VLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision 2.2.1-0-ga425c42)
[0000000002287118] core libvlc: Lancement de vlc avec l'interface par défaut. Utilisez « cvlc » pour démarrer VLC sans interface.
This application failed to start because it could not find or load the Qt platform plugin "xcb".

Available platform plugins are: directfbegl, directfb, eglfs, kms, linuxfb, minimal, minimalegl, offscreen, xcb.

Reinstalling the application may fix this problem.
Abandon

It has been solved with installation of lib64qt5dbus5.

So, please add these 4 packages as dependencies for vlc.
I rank it as major, because it prevents the use of vlc, which is a well-known program.

Reproducible:

Comment 2 Nicolas Lécureuil 2015-09-24 11:38:15 CEST 
maybe it should require:  qtbase5-common
Comment 3 David GEIGER 2015-09-24 12:53:05 CEST 
On my mga5_64 I get:

$ urpmq --whatrequires lib64qt5core5 |grep 'vlc'
lib64vlc-qt-qml0.9
lib64vlc-qt-widgets0.9
lib64vlc-qt0.9
phonon4qt5-vlc
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common

$ urpmq --whatrequires lib64qt5widgets5 |grep 'vlc'
lib64vlc-qt-qml0.9
lib64vlc-qt-widgets0.9
phonon4qt5-vlc
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common

$ urpmq --whatrequires lib64qt5gui5 |grep 'vlc'
lib64vlc-qt-qml0.9
lib64vlc-qt-widgets0.9
phonon4qt5-vlc
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common


$ urpmq --whatrequires lib64qt5dbus5 |grep 'vlc'

$ urpmq --whatrequires vlc-plugin-common
phonon-vlc
phonon4qt5-vlc
tano
vlc
vlc
vlc
vlc
vlc-plugin-common


So normally lib64qt5widgets5, lib64qt5gui5 and lib64qt5core5 should be automatically installed.
But not for lib64qt5dbus5.

Comment 4 David GEIGER 2015-09-24 12:59:14 CEST 
and:

$ urpmq --whatrequires lib64qtx11extras5 |grep 'vlc'
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common
vlc-plugin-common
Comment 5 Nicolas Lécureuil 2015-09-24 14:19:42 CEST 
is qtbase5-common installed ?
Comment 6 Luc Menut 2015-09-25 21:42:15 CEST 
As spotted by David, vlc already requires these packages through vlc-plugin-common
urpmq --requires-recursive vlc |grep qt
lib64qt5core5
lib64qt5dbus5
lib64qt5gui5
lib64qt5network5
lib64qt5widgets5
lib64qt5xml5
lib64qtx11extras5
qtbase5-common
qttranslations5

So we need to understand why they aren't installed for Olivier; perhaps vlc-plugin-common was installed (before vlc install) either with another arch (i586) or with a previous version (incomplete update from mga4) ??
Comment 7 Chris Nicoll 2016-02-08 05:18:35 CET 
Wish I had something informative to add; just wanted to say this bug report helped me get the menus back on VLC on my box (upgraded to MGA5 from 4) where lib64qt5gui5 was missing. Thanks all!

Good to see that all who hit this issue, managed to workaround it :-)

Closing as OLD, because Mageia 5 has officially reached its End of Life on December 31st, 2017 https://blog.mageia.org/en/2017/11/07/mageia-5-eol-postponed/
It only continued to get important security updates since then, but non-security bugs have no chance of still getting fixed.
