First thanks for the help/suggestions.
I’ve implemented each, then all the suggestions. My stutter is down ti 1 sec every 10 sec on this

  gst_rtsp_media_factory_set_launch (factory, "( "
      "videotestsrc ! video/x-raw,width=1920,height=1080,framerate=30/1 ! "
      "x264enc tune=zerolatency !rtph264pay name=pay0 pt=96 "
      "pulsesrc device=0 ! queue ! audio/x-raw,rate=48000 ! audioresample ! "
      "audio/x-raw,rate=8000 ! "
      "alawenc ! rtppcmapay name=pay1 pt=97 " ")”);

(gst-rtsp-server/examples/test-video.c)

I’ve got out of my depth here, can anybody see anything in the (GST_DEBUG=4) log
