I tried in my laptop Fedora 12 with gstreamer 0.10.29 works. But i put now
in server Fedora 12 and gstreamer 0.10.29 but does not work same error for
Centos 5.4 with gstreamer 0.10.20.

[root at ip-10-234-178-139 ~]# gst-launch -v udpsrc port=4444 ! fakesink
ERROR: pipeline could not be constructed: no element "udpsrc".
