Description Clint Moyer 2018-10-17 18:49:52 UTC

SUMMARY
Videos do not play with the Gstreamer Phonon backend. This is highly pronounced for users NOT using KDE as their desktop environment. Gwenview only works with the VLC backend for Phonon. Users not running KDE will not be able to switch their Phonon backend, as they have no access to Kcontrol/Phonon settings panel. Most operating systems offer the option between a Gstreamer or VLC backend for Phonon (a QT based API). Most operating systems default to using gstreamer to avoid proprietary codecs. Users who want to run Gwenview will have to first remove phonon-qt5-gstreamer and then install phonon-qt5-vlc, before installing Gwenview to use the right backend.

STEPS TO REPRODUCE
1. If phonon-qt5-vlc exists on your machine, remove it
2. Install phonon-qt5-gstreamer
3. Install Gwenview
4. When running Gwenview, will not be able to load videos

OBSERVED RESULT
Videos not playing with the often standard Gstreamer backend for Phonon

EXPECTED RESULT
Videos should play

I have both gstreamer and vlc backends installed on neon dev unstable and I can confirm that gwenview does not play videos when I prefer gstreamer backend in system setings > multimedia > audio and video.

However I can not confirm the problem on Arch Linux.

Operating System: Arch Linux 
phonon-qt5-gstreamer 4.9.0-5
phonon-qt5-vlc 0.10.1-3
KDE Plasma Version: 5.14.1
Qt Version: 5.12.0
KDE Frameworks Version: 5.51.0
