I wanted to stream video of myself and my screen at the same time. My
plan was to put the video of myself on my screen and stream the entire

phone, including in a web browser using WebRTC which supports
peer-to-peer video chat between two web browsers, so it should be easy
to show the video from my phone's camera in a browser window on my
desktop. Unfortunately, I couldn't find any straightforward solution for
setting up just a peer-to-peer video link.

local connections, so it may not work if the two devices are not on the
same network. Only the signaling to set up the connection goes to the
minimal-webrtc server, the actual video will be sent peer-to-peer over
the local network.
To get just the video as a bare window with no decorations, use
