SEND your QRQ CW AUDIO to the "other" QRQ CW OP
*********************************************************************
gst-launch-1.0 jackaudiosrc ! audio/x-raw,channels=1 ! audiorate ! audioconvert ! opusenc bitrate=256000 frame-size=2.5 ! rtpopuspay ! udpsink host=(ip address of the other QRQ CW OP) port=5008
RECEIVE jpeg picture from the "other" QRQ CW OP
*******************************************************************
gst-launch-1.0 -v udpsrc port=5007 ! decodebin ! videoconvert ! ximagesink
RECEIVE QRQ CW AUDIO from the "other" QRQ CW OP
