RTP pipeline trouble

I'm working with the Weston compositor, GStreamer 1.16.3, and remote
outputs. Weston sets up the remote output using this pipeline:
rtpbin name=rtpbin appsrc name=src ! videoconvert ! video/x-raw,format=I420
! jpegenc ! rtpjpegpay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 !
udpsink name=sink host=192.168.0.106 port=35500 rtpbin.send_rtcp_src_0 !
udpsink host=192.168.0.106 port=35501 sync=false async=false udpsrc
port=35502 ! rtpbin.recv_rtcp_sink_0
I'm attempting to view on 192.168.0.106 using:
gst-launch-1.0 rtpbin name=rtpbin udpsrc
caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=JPEG,payload=26"
port=35500 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtpjpegdepay ! jpegdec !
autovideosink udpsrc port=35501 ! rtpbin.recv_rtcp_sink_0
rtpbin.send_rtcp_src_0 ! udpsink port=35502 sync=false async=false
The last log entry is `child 'rtpjpegdepay0' changed state to 4(PLAYING)
successfully`. Only no video window.
On the wire I do see periodic RTCP receiver reports, and ARP requests
originating from the source pipeline.
Is anything obviously wrong with my receive pipeline?
Thanks,
Joel
