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.
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, but it's not obvious to me how I can get video from the Pi Zero over Ethernet and then get it to show up as a project background in a Scratch program.
Anyone got any ideas as to where I could start? I have intermediate raspbian, python and Scratch skills.
Thanks in advance,
