Specification

https://github.com/screen-share/capture-all-screens

Summary

Web apps will be able to capture multiple surfaces at once.

This feature introduces a new API "getAllScreensMedia()" that allows
developers to request several surfaces at once (instead of only one with
"getDisplayMedia()"). This API will auto-accept capture requests (for
managed sessions only), guarded by policies that have to be explicitly set
by the device owners and with clear usage indicators so that users are
aware of capturing at all times.


Blink component

Blink <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink>

Motivation

Customers have asked to capture multiple surfaces (screens in particular),
e.g. [1, 2].
