Thanks, it works now! Just as you said I had to install "gstreamer1.0-plugins-base" to get a non NULL GstElement and gstreamer1.0-* to be able to play media files. <div class="gmail_extra"> <div class="gmail_quote"> On Mon, Dec 17, 2012 at 4:30 PM, Tim-Philipp Müller <<a href="mailto:t.i.m@zen.co.uk" target="_blank">t.i.m@zen.co.uk</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> <div class="HOEnZb"><div class="h5">On Mon, 2012-12-17 at 16:21 +0200, Jiergir Ogoerg wrote: Hi, > I'm using v1.0.3 and this line returns NULL: > GstElement *refPlay = gst_element_factory_make("playbin", NULL); > //refPlay is NULL > > Same issue with "playbin2".

(gst-inspect-1.0 is in the gstreamer1.0-tools package) Do you have gstreamer1.0-plugins-base installed? If not, perhaps try: sudo apt-get install gstreamer1.0-* Cheers -Tim _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> </div>
