Not returning from gst_pad_push() in rtpbin element

Hi All,
I am using rtpbin element of gst-plugins-farsight-0.12.9 compiled
with jrtplib support on a FC6 platform. I am running the following pipeline
: -

"gst-launch filersrc location=<MPEG4 File> ! mpeg4vidoeparse ! video/mpeg,
width=352, height=288, framerate=5/1 ! rtpmp4vpay mtu=1400 ! rtpbin
localport=5000 destinations=10.60.3.63:5000"

No data is streamed. When i traced the rtpbin plugin, i found out that
gst_pad_push() function present in the function push_packet_on_pad() in the
file jrtplib_c.cpp is not returning. I also found out that
gst_dynudpsink_render() function of dynudpsink element is not getting called
indicating no data is being pushed.

Can you tell where i am going wrong.

Regards
Ani
