Aha, I thought it is reproducible with all pipelines sorry :)

Here you go:

server:
gst-launch-1.0 -v filesrc location= HoneyBee_1920x1080.I420 ! rawvideoparse 
format=i420 width=1920 height=1080 framerate=60/1 ! rtpvrawpay ! udpsink
host=127.0.0.1 port=5000 sync=false 


client:
gst-launch-1.0 udpsrc port=5000 caps="application/x-rtp, media=(string)video,
clock-rate=(int)90000, encoding-name=(string)RAW, sampling=(string)YCbCr-4:2:0,
depth=(string)8, width=(string)1920, height=(string)1080,
colorimetry=(string)BT709-2, payload=(int)96, ssrc=(uint)428940642,
timestamp-offset=(uint)1245392745, seqnum-offset=(uint)15302,
a-framerate=(string)60" ! rtpvrawdepay ! vaapih264enc rate-control=cbr
bitrate=2000 ! fpsdisplaysink video-sink=fakesink text-overlay=false sync=false


Or you can reproduce it with the below steps:

Install rawvideosink from https://github.com/sreerenjb/gst-rawvideosrc

gst-launch-1.0  rawvideosrc location=HoneyBee_1920x1080.I420 !  video/x-raw,
format=I420, width=1920, height=1080 !   vaapih264enc rate-control=cbr
bitrate=2000 quality-level=7  ! fakesink
