Gstreamer 1.2.3 dont work with udp multicast in Windows 7. Gstreamer does not
transmit or receive multicast packets. 
I have scanned ports by Wireshark, but there is not packets sended from
Gstreamer. There is no log output with debug option GST_DEBUG=udp*:6 on sender
side(server side). Pipeline on sender side  
gst-launch-1.0 --gst-debug=udp*:6  videotestsrc ! video/x-raw,format=RGB,
width=320, height=240, framerate=30/1! videoconvert ! avenc_mpeg4 ! rtpmp4vpay
config-interval=1 ! udpsink host=224.1.1.1 port=5004 auto-multicast=true

Pipeline of receiver side

media=(string)video" ! rtpmp4vdepay ! avdec_mpeg4 ! videoconvert !

Debug output of receive side with option --gst-debug=udp*:6 is
