Since the only way for a website to halt media playback in a cross-origin iframe is to destroy the frame, this feature should help said websites to improve performance by removing the need to destroy and re-create the media-playing frame everytime playback needs to be paused/resumed.
Blink component Blink>Media<https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EMedia> Motivation Web applications that host embedded media content via iframes may wish to respond to application input by temporarily hiding the media content. These applications may not want to unload the entire iframe when it's not rendered since it could generate user-perceptible performance and experience issues when showing the media content again. At the same time, the user could have a negative experience if the media continues to play and emit audio when not rendered. This proposal aims to provide web applications with the ability to control embedded media content in such a way that guarantees their users have a good experience when the iframe's render status is changed. Initial public proposal None TAG review None TAG review status Pending Risks Interoperability and Compatibility None Gecko: No signal WebKit: No signal Web developers: The web community seems to be interested in this feature (Proposal: pause iframe media when not rendered · Issue #10208 · whatwg/html (github.com)<https://github.com/whatwg/html/issues/10208>). Even though we may need to iterate on the user-facing API, the feature is ready for implementation, because we anticipate that the majority of the feature implementation will be the same even if there are changes to be made there. 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?
