Comment 1 Jiri Slaby 2013-03-27 12:55:01 UTC 
I see, this is a problem of digikam to be linked against *both* gst 0.1 and 1.0.

GLib-GObject-WARNING **: cannot register existing type `GstAudioClock'
GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed
GLib-GObject-CRITICAL **: g_object_new: assertion `G_TYPE_IS_OBJECT (object_type)' failed

Comment 2 Jiri Slaby 2013-03-28 09:32:57 UTC 
AFAICS gst 0.1 comes from opencv and gst 1.0 from qt webkit...
Comment 3 Myriam Schweingruber 2013-04-13 07:51:35 UTC 
The problem is upstream in gstreamer, not in the phonon backend.
Comment 4 Myriam Schweingruber 2013-04-14 00:01:23 UTC 
*** Bug 318298 has been marked as a duplicate of this bug. ***
Comment 5 caulier.gilles 2018-08-21 10:43:58 UTC 
Problem is not reproducible since digiKam use QtAv framework +ffmpeg to handle video files.
