From Cosmostreamer to OBS

UDP Raw H264

It is an incoming UDP stream, it may be blocked by Windows firewall. Disable firewall or add exception rule if not worked.

Enable UDP Raw H264 streaming in Cosmostreamer device settings. 192.168.1.67 it's my laptop IP, in your case use proper IP

And use this pipeline for OBS GStreamer source

udpsrc port=3000 buffer-size=600000000 ! h264parse ! avdec_h264  ! video.
