tcpserversink and tcpclientsrc don't appear to stream rtp data in Windows 10 (and Windows 7) environment. The problem reproduces for me with gstreamer 1.12.2 and 1.12.4.

Steps to reproduce

Turn off firewall in Windows
Install gstreamer using gstreamer-1.0-x86_64-1.12.4.msi and selecting full installation
Install gstreamer-devel using gstreamer-1.0-devel-x86_64-1.12.4.msi and selecting full installation
Start command line and run this server pipeline gst-launch-1.0 --gst-debug="tcp*:7,3" videotestsrc ! x264enc tune=zerolatency ! rtph264pay ! rtpstreampay ! tcpserversink host=127.0.0.1 port=5000
Start 2nd command line and run this client pipeline gst-launch-1.0 --gst-debug="tcp*:7,3" tcpclientsrc host=127.0.0.1 port=5000 ! fakesink silent=false
Noticed the problem where no rtp data flows between server and client

Notes:
a) Same pipelines work in Raspberry Pi (linux) with gstreamer 1.10.4
b) If I use udpsink and udpsrc the pipelines work in Windows, e.g. these pipelines work:
gst-launch-1.0 -v videotestsrc is-live=true ! videoconvert ! videoscale ! video/x-raw,format=I420,width=800,height=600,framerate=25/1 ! x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5000
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264,payload=96 ! rtph264depay ! avdec_h264 ! autovideosink

Thanks
