Explainer https://github.com/screen-share/element-capture/blob/main/README.md Specification https://screen-share.github.io/element-capture Summary 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. Blink component Blink>GetDisplayMedia <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EGetDisplayMedia> TAG review We are holding off on the request for a TAG review until we get some more developer feedback about the API shape. TAG review status Pending Risks Interoperability and Compatibility Gecko: Under consideration ( https://github.com/mozilla/standards-positions/issues/857) WebKit: No signal (https://github.com/WebKit/standards-positions/issues/280) Web developers: Positive See upvotes and comments on the following: - https://github.com/WICG/proposals/issues/73 - https://twitter.com/quicksave2k/status/1583388663597015042 Other signals: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? Goals for experimentation * Solicit more informed Web developer feedback to validate the API shape. * Ensure that the feature works correctly in conjunction with adjacent features. Debuggability No changes to DevTools are intended. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)? No This API is supported on all desktop platforms. Mobile platforms are unsupported because screen-capture itself is unsupported on those platforms. Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?
