 |
|
After my latest world upgrade, KDE Dragon Player (and any other KDE video software as far as I can tell) stopped playing videos. When I start Dragon Player from a terminal, I see the following messages. The messages are repeated serveral times and in random order: | Code: | WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend plugin could not be loaded
WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::VideoWidget ( no objectName ).
WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no objectName ) to Phonon::AudioOutput ( no objectName ). |
I see the same messages again, if I either try to open a video file are drag and drop a video file into the Dragon Player.
Moreover, I noticed that the system tray (at the bottom right next to the clock) only shows a single speaker symbol. There have been two previously. |

After some investigation the following output caught my attention: | Code: | equery g media-libs/phonon

Phonon 4.11 had a dependency on media-libs/phonon-gstreamer, but Phonon 4.12 does not. (Or I am blind). GStreamer has been my default backend ever since. |
