Explainerhttps://github.com/w3c/mediacapture-region/blob/main/README.md Specificationhttps://w3c.github.io/mediacapture-region/ Summary We introduce a performant and robust API for cropping a self-capture video track. (Recall that applications may *already* video-capture the tab in which the application is run using getDisplayMedia(). Using our new Region Capture, such an application may now *crop* that track and remove some content from it; typically before sharing it remotely.) Blink componentBlink <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink> TAG reviewhttps://github.com/w3ctag/design-reviews/issues/710 TAG review statusNot applicable Risks Interoperability and Compatibility Gecko: No signal (https://github.com/mozilla/standards-positions/issues/621) WebKit: No signal ( https://lists.webkit.org/pipermail/webkit-dev/2022-March/032157.html) Web developers: Strongly positive This work saw strong support from Web developers inside of Google (Meet, Docs, Slides). Public statements of support coming. Other signals: Ergonomics N/A Activation Unchallenging to use. Security This is a mechanism by which an application purposefully strips away information which it already has access to (via pre-existing mechanisms such as getDisplayMedia). 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 Evaluate the usefulness of the feature and gather Web-developer feedback about how it may improve. Reason this experiment is being extended - Continue soliciting feedback from developers while getting ready to ship. - Partners have invested significantly in this experimental API. Out of consideration for them, when we eventually request to ship, we will request gapless shipping. This implies extending the experiment up to the point of shipping. (Note that an intent-to-ship will also be sent today.) - We therefore request extending by the usual 3 milestones - so up to and including m104. However, we hope this will be shipped before the extended period elapses. Debuggability - Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?No Supported on all desktop platforms, but not on mobile platforms, as the prerequisite API of getDisplayMedia is currently only available on desktop.
