gst_element_factory_make errors in gstreamer-1.0

[mihaita]

Hello,

     I have created a gstreamer app in Eclipse and i have the following
runtime emssages:

(process:1510): GStreamer-CRITICAL **: gst_element_factory_make: assertion
'gst_is_initialized ()' failed

(process:1510): GStreamer-CRITICAL **: gst_element_factory_make: assertion

I have read about possible issues. gst_init is called and the pipeline
string used by gst_parse_launch seems to be correct.

I do not create pipeline elements by calling gst_element_factory_make,
instead I have the pipeline defined already:

pipeline = gst_parse_launch("appsrc name=appsrc_element block=true !
video/x-h264,profile=\"high-4:4:4\" "\
    		                    "  width=720,height=480,framerate=30/1  "\
    		                    " ! identity check-imperfect-timestamp=true ! "\
    		                    "videoconvert ! x264dec ! video/x-raw,format=RGB
"\
    		                    "! rtpvrawpay ! udpsink host=10.2.149.137 ",
&error);


Does anybody know what possible reasons could be for this errors?

Thanks,
     Mihaita
