Description

API for capturing a subtree of the DOM.

Given a video MediaStreamTrack obtained through pre-existing means to initiate tab-capture, Element Capture allows mutating the track to only capture a subtree of the DOM starting at a given Element.

The API bears some resemblance to the Region Capture API, but affords greater flexibility for applications, because occluding and occluded content are both excluded from the capture.
