Thanks! Is there anything specific you want to learn more about? At a high level we run a fork of Chromium in the cloud, capture the desktop using gstreamer and stream it back to everyone using Mediasoup.

The folks at SideGuide made the interactive demo for us — we love it too.

Very cool! Is gstreamer used end to end? Mostly curious if you are using CEF (via cefsrc) and webrtcbin, or if you handled the input and output differently.

Thanks! Actually it's neither: we run full Chromium rather than CEF and Mediasoup for webrtc. We have looked into webrtcbin as well, but it wasn't the best fit for us.

Interesting! I've been using webrtcbin for some production work but it's been broadcasting of low latent internally used video with no user input back. I've seen demos of user input with webrtcbin, but have never done it in practice. If you can, do you mind sharing why webrtcbin wasn't a good fit for you (or why MediaSoup was better)?

webrtcbin is nice for one-to-one, but we were looking for something that's a better fit for one-to-many, which is where mediasoup came in. That being said, mediasoup is quite complex from a maintainability perspective since it's designed to handle several use cases, so we plan on making our own webrtc streaming solution in the future that's designed with only one-to-many in mind
