just a polite ping - any ideas on what the problem is here? Alternatively, is there a video file + workflow that is known to allow streaming without artifacts ?

Have you tried FFMPEG to push the stream to the server? Might be just bad parameters in Gstreamer. I am not familiar with Gstreamer at all, only using it in OBS as a playback plugin since it doesn't crash OBS while trying to decode a corrupt stream in case of network conditions being too bad.
