Multicast RTP not working on Windows

Hi,

I'm using this pipeline on the sender's side:


*gst-launch-1.0 appsrc ! videoconvert ! video/x-raw, height=576, width=720,
format=UYVY ! rtpvrawpay ! udpsink host=224.1.1.1 port=5004*
and I can play it on the receiver's side on Ubuntu 14.04 using:


*gst-launch-1.0 udpsrc address=224.1.1.1 port=5004 ! "application/x-rtp,
media=(string)video, clock-rate=(int)90000, encoding-name=(string)RAW,
sampling=(string)YCbCr-4:2:2, depth=(string)8, width=(string)720,
height=(string)576, colorimetry=(string)BT601-5, payload=(int)96" !
rtpvrawdepay ! videoconvert ! autovideosink*
However, the same receiver's pipeline does not work on Windows. It starts
listening on the port, but the sink window never starts. If I replace the
multicast IP by a unicast address, it works fine.

I've seen this problem noticed before also by someone (
https://bugzilla.gnome.org/show_bug.cgi?id=725872). Was wondering if it's
fixed and works fine and is an OS problem or a gstreamer bug. Any help
would be much appreciated.

Thanks,
Anuj
