I made the following:

sender:

gst-launch -v gstrtpbin name=r \
   rtspsrc location=rtsp://root:kbcrj@10.10.10.11/axis-media/media.amp ! 
rtph264depay ! decodebin ! \
   ffmpegcolorspace ! \
   videoscale ! 'video/x-raw-yuv,format=(fourcc)I420,width=320,height=240' \
   ! rtpvrawpay ! r.send_rtp_sink_0  \
   r.send_rtp_src_0 ! udpsink host=127.0.0.1 port=5000 \
   r.send_rtcp_src_0 ! udpsink host=127.0.0.1 port=5001 sync=false 
async=false \
   udpsrc port=5002 ! r.recv_rtcp_sink_0 | while read line ; do
   if [[ $line =~ .*GstUDPSink.*caps.*video.* ]]
   then
      echo $line | sed -e 's/.*caps = //' | sed -e 's/ //g' > caps_11.txt
   fi
   echo $line
done


receiver:

gst-launch gstrtpbin name=rtpbin \
   udpsrc caps=$CAPS port=5000 ! rtpbin.recv_rtp_sink_0  \
   rtpbin. ! rtpvrawdepay ! \
   clockoverlay halignment=1 text="`date +%d.%m.%y`" font-desc="Sans 28" ! \
   ffenc_flv ! ffmux_flv ! filesink async=false sync=false 
location=$FDIR/$FFNAME \
   udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0  \
   rtpbin.send_rtcp_src_0 ! udpsink port=5002 sync=false async=false

and it works, but after I add format=(fourcc)I420 to the senders 
pipeline. Without this line nothing was received.
