I've written a Qt4.4 applications with plays a video using Phonon::VideoPlayer. On a SuSE machine, it works perfectly. However it has to be run on a Fedora 8 machine because of other dependencies. But there it shows just the first frame and the video stops playing/freezes, while the rest of the application remains working. In console it prints the following:

(<unknown>:4168): GStreamer-WARNING **: Failed to load plugin '/usr/lib/gstreamer-0.10/libgstffmpeg.so': /usr/lib/libavcodec.so.51: Kann den Segment-Schutz nach der Relozierung nicht wieder herstellen: Keine Berechtigung

Translation of the german part: Could not reestablish segment-protection after relocating: Not granted

or the other error message

(<unknown>:4168): GStreamer-WARNING **: pad mpegaudioparse0:src returned caps which are not a real subset of its template caps

It uses the gstreamer-backend. Other media players which natively use gstreamer could play the videos without problems. This problem seems to be independend of the media format (same with mp4, mpeg, avi, ...).

Any suggestions?
