Gstreamer webrtc streaming

[VanderBieu]

Question

Sample code
gst-launch-1.0 videotestsrc \ ! video/x-raw,width=1920,height=1080,format=I420 \ ! x264enc speed-preset=ultrafast bitrate=2000 \ ! video/x-h264,profile=baseline \ ! whipclientsink signaller::whip-endpoint=http://localhost:8889/mystream/whip

not working. Log indicates that this stream never reached the mediamtx server. How to make this work?
My platform is windows-amd64, my gstreamer version is 1.24.4, mediamtx version 1.8.4
