Hi,Please try the following cmd which works fine here on my stuffs.

• veye_raspivid (stream over UDP using gstreamer)
  PC side,using gstreamer(Powershell recommended)

gst-launch-1.0 -v udpsrc port=5321 ! gdpdepay ! rtph264depay ! avdec_h264 ! autovideosink sync=false

RPI side

./veye_raspivid -b 4000000 -t 0 -o -  | gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96 ! gdppay ! udpsink host=x.x.x.x port=5000 sync=false

H.264 encoding on bitrate 4Mbps.

x.x.x.x is HOST PC IP address.You need to run the pc-side program first and then run the Raspberry Pi-side program.

@veye_xumm Foolishly I got the server program running first.
I run the client program first, then the server program, and it works fine.
Anyway, thank you.
It helped a lot.
