OBS Gstreamer plugin

For Windows

1. Download and install OBS https://obsproject.com/download
2. Download and install Gstreamer https://gstreamer.freedesktop.org/download/ (MinGW 64-bit runtime installer, use Full installation)
   • IMPORTANT! Add gstreamer bin directory into PATH environment variable (System preferenses > Additional system params > Environment variables). Default bin directory location is C:\gstreamer\1.0\mingw_x86_64\bin
3. Download OBS Gstreamer plugin https://github.com/fzwoch/obs-gstreamer/releases (latest release, obs-gstreamer.zip file)
   • Extract obs-gstreamer.dll file from obs-gstreamer.zip
   • Copy obs-gstreamer.dll into C:\Program Files\obs-studio\obs-plugins\64bit directory (if OBS installed into default destination)
4. Run OBS, open "add source" menu, you'll see GStreamer Source

With default pipeline you must see default GStreamer test video

videotestsrc is-live=true ! video/x-raw, framerate=30/1, width=960, height=540 ! video. audiotestsrc wave=ticks is-live=true ! audio/x-raw, channels=2, rate=44100 ! audio.

From Cosmostreamer to OBS

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 GStreamer source

udpsrc port=3000 ! h264parse ! avdec_h264  ! video.
