UdpSink in GStreamer is not working in Windows

Question

I am new to GSTreamer. I tried to upsink a video using GStreamer. While running the folloing command,

gst-launch-1.0 videotestsrc ! udpsink port=5200

I get warnings as follows.

WARNING: from element /GstPipeline:pipeline0/GstUDPSink:udpsink0: Attempting to send a UDP packets larger than maximum size (115200 > 65507)
Additional debug info:
gstmultiudpsink.c(715): gst_multiudpsink_send_messages (): /GstPipeline:pipeline0/GstUDPSink:udpsink0:
Reason: Error sending message: A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself.

What is the problem in GStreamer parameters?

Is there anything missing in that?

You need payloading before before transmitting a video on UDP.

 gst-launch-1.0 videotestsrc ! rtpraw4vpay ! udpsink port=5200

But transmitting raw video over udp is not preferred. A better way to transmit video is to encode it to reduce the size. I'd prefer h264 encoding for optimum size.

gst-launch-1.0 videotestsrc ! x264enc ! video/x-h264, stream-format=byte-stream ! rtph264pay ! udpsink port=5200

You will receive this stream with

gst-launch-1.0 udpsrc port=5200 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink
