SpecificationNone Summary The prefixed HTMLVideoElement-specific fullscreen APIs have been deprecated since approximately M38. They were replaced by the Element.requestFullscreen() API, which first shipped un-prefixed in M71, in 2018. As of 2024, most browsers have had support for the un-prefixed APIs for a few years now. This feature tracks removing the following APIs from HTMLVideoElement: - readonly attribute boolean webkitSupportsFullscreen; - readonly attribute boolean webkitDisplayingFullscreen; - void webkitEnterFullscreen(); - void webkitExitFullscreen(); // Note the different capitalization of the "S" in FullScreen. - void webkitEnterFullScreen(); - void webkitExitFullScreen(); These methods are now only aliases for the modern API. Their use has declined steadily over the years. Blink componentBlink>Fullscreen <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink%3EFullscreen> TAG reviewNone TAG review statusNot applicable Chromium Trial NameDeprecatePrefixedVideoFullscreen Origin Trial documentation link https://developer.mozilla.org/en-US/docs/Web/API/Fullscreen_API WebFeature UseCounter namekPrefixedVideoSupportsFullscreen Risks Interoperability and Compatibility The main risk is that websites that are *only* using this API will be broken. However, the usage of these APIs is low, and the replacement APIs are available and supported across browsers. Starting in M125, this API was disabled by default. A deprecation trial was conducted, allowing registrants to temporarily re-enable the APIs while they update their websites. No negative feedback surfaced during the deprecation trial. The trial is concluding in M131. Additionally, an enterprise policy was added to allow enterprise customers who couldn't register for an OT to transition away from the API. No feedback was surfaced by enterprise customers either, and the policy will be deprecated and removed at the same time as these APIs will be permanently removed. *Gecko*: N/A Gecko has their own set of prefixed APIs. *WebKit*: Closed Without a Position ( https://github.com/WebKit/standards-positions/issues/306) *Web developers*: No signals *Other signals*: Security The APIs to be deprecated are aliases for the replacement APIs at this point. Removing them should not exercise new code paths, or open up new attach surfaces. 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? None Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?Yes Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes Tests tracking removal of these prefixes: https://wpt.fyi/results/fullscreen/api/historical.html?label=experimental&label=master&aligned&q=%2Ffullscreen%2Fapi%2Fhistorical.html Test covering the new fullscreen APIs: https://wpt.fyi/results/fullscreen/api?label=master&label=experimental&aligned&q=%2Ffullscreen%2Fapi%2F Flag name on about://flagsNone Finch feature namePrefixedVideoFullscreen Requires code in //chrome?False Estimated milestones Shipping on desktop 132 Origin trial desktop first 125 Origin trial desktop last 131 DevTrial on desktop 125 Shipping on Android 132 DevTrial on Android 125 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
