Hi Wim & Lutz Müller,
Thanks a lot for your reply.
I checkout the latest code for gstreamer, gst-plugins-base, gst-plugins-good, gst-plugins-bad & gst-plugins-ugly from
$cvs -d:pserver:anoncvs at anoncvs.freedesktop.org:/cvs/gstreamer co modulename
and installed into my system (linux fedora 6).
I saw in RELEASE file that code changes for rtsp support in playbin element (336301 : [playbin] can't handle RTSP source) has been in cluded in this code.
when I am trying to play 3gp and mov then getting the following errors:
Command of 3gp:
$gst-launch-0.10 --gst-debug=2 --gst-debug-no-color playbin uri=rtsp://192.168.3.9/sample_50kbit.3gp
