Over the last weeks, the @w3c #WebRTC Working Group released two first public working drafts of new #APIs to help with improved screen-sharing capabilities in Web apps #timetogiveinput

The first API, Capture Handle Identity, provides a mechanism for a Web #app (e.g. videoconf) capturing the content of another one (e.g. slide deck) to collaborate => the users sharing their screen can navigate slides from within the videoconf tool w3.org/TR/capture-handle-ide…

This is done by letting the captured Web #app expose info to the capturing one to allow the two apps to collaborate. Read this explainer that lists more use cases as well as sample code: github.com/w3c/mediacapture-…

This #API is shipping in #Chrome 102, which allows running the following demos: w3c.github.io/mediacapture-h…

As always, the work is happening in a #github repo, where a complementary work to describe generically affordances a captured app may expose to its capturer is also investigated: github.com/w3c/mediacapture-…

Would virtual camera functionality make sense here? Video-conferencing is usually a wall of faces, where often a wall of CONCURRENT shares makes more sense, but only 1 person can 'share screen' and after that sharing stopped, another can.

The limit of videoconferencing systems to a single screen share is a choice of these systems vendors (probably because screen content often requires to be close to fullscreen to be readable) - #WebRTC has no such restriction. How would concurrent screen shares be used?

pre-Corona I taught workshops where I (or helper) walked through physical classroom and peeked at (often not very technical) students' screens. I'm looking to do the same in a remote setting. For now the best I can do I think is, make ultra-short @obsproject manual for this task
