我正在开展一个项目，我需要做这项工作

gst-launch-1.0 -e \
  videomixer name=mix \
      sink_0::xpos=0   sink_0::ypos=0 sink_0::alpha=0 \
      sink_1::xpos=640 sink_1::ypos=0 sink_1::alpha=1 \
      sink_2::xpos=0   sink_2::ypos=0 sink_2::alpha=1 \
    ! glshader location=distortion.frag ! glimagesink sync=false \
  videotestsrc pattern="black" \
      ! video/x-raw,width=1280,height=720 \
      ! mix.sink_0 \
  rtpbin name=rtpbinleft latency=250 ntp-sync=true do-retransmission=0 \
    udpsrc caps=application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264 port=5000 ! rtpbinleft.recv_rtp_sink_0 \
