Specification

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