udpsink fails when multicast ip address is given. It works fine when another PC
ip address(Unicast) is given.

Steps to reproduce:
My requirement is to multicast a video.
I am using the below command to multicast the video:
gst-launch -v gstrtpbin name=rtpbin filesrc location=1.avi ! decodebin2 
name=decode decode. ! ffmpegcolorspace ! videoscale ! videorate !
video/x-raw-yuv,width=352,height=288,framerate=15/1 ! ffmpegcolorspace !
ffenc_h263p ! rtph263ppay ! rtpbin.send_rtp_sink_0 rtpbin.send_r rtp_src_0 !
queue ! udpsink host=150.158.73.74 port=5000

When I give another PC IP address then it work fine(UNICAST) and I am able to
see the video in another PC but when I give the multicast IP address then I get
the below error:
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstUDPSink:udpsink0: Could not
get/se
t settings from/on resource.
Additional debug info:
..\..\..\..\..\Source\gst-plugins-good\gst\udp\gstmultiudpsink.c(906):
gst_multi
udpsink_configure_client (): /GstPipeline:pipeline0/GstUDPSink:udpsink0:
Could not join multicast group (10022): A
Setting pipeline to NULL ...
Freeing pipeline ...


Same goes for udpsrc also, if we try to give a multicast ip address in udpsrc
then it fails showing the same above error message. But it work fine when
another PC ip address(UNICAST) is given.

I am using OSS build(GStreamer 0.10.28 version) on Window OS.
