title: Viewing a remote camera stream in Scratch
body: <p>I'm doing a project for my son where we're going to have a remote Pi Zero with a camera and various sensors and actuators, connected via wired Ethernet to a Pi 3 as a controller with a Scratch GUI.</p>
  
  <p>Seems like I can get a local camera to send video to the background of the Scratch project, or I can get a remote camera to stream back to e.g. VLC Player using RTSP.</p>
  
  <p>Being as how I want to teach my son how to build a scratch GUI on the Pi3 to remote control the sensors and actuators on the Pi Zero, I'd really like the rtsp video stream to show up as the Scratch project background so I don't have to have a separate VLC window open.</p>
  
  <p>So... how to pick up an RTSP video stream and send it to the Scratch backdrop?</p>
  
  <p>Anyone got any ideas as to where I could start? I have intermediate raspbian, python and Scratch skills.</p>
  
  <p>Thanks in advance,
  Ben</p>
