[Qt-interest] phonon and rtsp mpeg4 stream

Dear List,

I try to get the picture from a Axis Network camera.

With mplayer and vlc i can receive the stream with

mplayer  -mc 10 -v rtsp://192.168.1.200/mpeg4/media.amp

vlc -v rtsp://192.168.1.200/mpeg4/media.amp

I have tried it with phonon like this:

###
QUrl url("rtsp://192.168.1.200/mpeg4/media.amp");

mediaObject = new Phonon::MediaObject(this);
videoWidget = new Phonon::VideoWidget(this);
Phonon::createPath(mediaObject, videoWidget);
mediaObject->play();
###

The output in the command line is:

###
(<unknown>:17647): GStreamer-CRITICAL **: 
Trying to dispose object "sink", but it still has a parent "decodebin0".
You need to let the parent manage the object instead of unreffing the
object directly.

**
GStreamer:ERROR:gstghostpad.c:1131:gst_ghost_pad_set_target: assertion
failed: (internal)
###

The question is now:

Is this a gstream problem?
Is this a phonon problem?
Is this a caller problem?

I have also tried to get the stream display thru gst-launch-0.10 but
I'am not ver familiar with gstreamer so I was not able to see the
stream.

Please can anybody help me?

I will also get the stream on Windows with phonon is this also possible?

BR

Aleks
