Running a video with QMediaPlayer : undefined symbol

[hisoft]

Hi all,

I'm trying to run a simple application that plays a video with Qt Multimedia but i got the following error :
@
(TestMultimedia:17734): GStreamer-WARNING **: Failed to load plugin '/usr/lib64/gstreamer-0.10/libgstfcdec.so': /usr/lib64/gstreamer-0.10/libgstfcdec.so: undefined symbol: __gst_debug_min
@

It looks like i have a bad version of libgstfcdec.so. Am i right and how to solve this issue ?

Can any one help me please ?

Thanks in advance.

When i test my file with gst-lauch command, i can read the media file (in mp4 format). I think that if i point to gst-launch-1.0 rather than gstreamer-0.10 it will be ok. But how to do it ? meaning how to point to /usr/lib64/gstreamer-1.0/... ?
