Safari 11 (and currently Safari 14) is using the so-called “automatic inference engine”, which decides, if media elements with sound are allowed to auto-play on the visited website by default, which won’t be allowed for most websites, according to the Safari team.

However, Apple has since updated its developer content to include autoplay information on its best practices page. Only the original changelog in the app store held this information: Safari 11.0 originally shipped with iOS 11.0 and macOS 10.11 – but currently is on the 14.1th iteration which was released on September 16th, 2020, and continues to implement the following autoplay policies: In addition to that, both browsers are going to introduce an automated approach, which decides if auto-play will be blocked for media elements with sound in general or if auto-play is disabled at all. The video element will automatically pause when and if the video becomes unmuted without user interaction or if the video is no longer onscreen.Īdditional options are available in the respective website preferences pane to allow or disable autoplay, disable audio in general, or more. For any app or service to successfully run an autoplay element, the video must either come without an audio track or with a muted attribute. Since then, Apple has made significant improvements to its playback and autoplay capabilities. Thus providing users with more control over the autoplay capabilities on individual websites. The main goal of these policies was to improve a user’s browsing experience by eliminating distractions and surprising media playbacks of unmuted content. Updates to the autoplay policies in Safari and Chrome could have significant implications for both advertisers and content providersĪs of September 2017, Safari 11 on macOS and iOS, as well as Chrome for Desktop and Mobile introduced a new auto-play policy.
