No worries :-)  Here it is:
gst-launch -e -v v4l2src device=/dev/video1 queue-size=16 \
    ! video/x-raw-yuv,format='(fourcc)UYVY',width=720,height=480,framerate=30/1 \
    ! tee name=v-src \
      v-src. ! queue leaky=upstream ! videoscale ! "video/x-raw-yuv,width=320,height=240" ! gdppay ! shmsink socket-path=/tmp/shm-stream.sock \
      v-src. ! queue leaky=upstream ! videoscale ! "video/x-raw-yuv,width=240,height=120" ! gdppay ! shmsink socket-path=/tmp/shm-preview.sock \
      v-src. ! queue leaky=upstream ! shmsink socket-path=/tmp/shm-record.sock \
