Hello premier.one, WebKit uses the User Activation API <https://webkit.org/blog/13862/the-user-activation-api/> to detect whether the user has interacted with the page for the purpose of allowing audible auto-play. And as documented in that blog post, User Activation does not propagate to cross-origin frames.
All that said, I’m confused by this part of your email: > ...occurs because our video content is hosted on a separate domain for > technical reasons. It looks like both your main content origin (https://premier.one) is the same origin as the video frame (/play/embed/…). So they should be Same-Origin rather than Cross-Origin. I verified this with the Web Inspector: > window.parent.location.origin === window.origin < true I also verified that you’re able to access the parent document from within your iframe context: > window.parent.document.documentElement < <html data-capo lang="ru" style="--vh: 4.46px;" class="scroll-lock">…</html> So I’m confused why this might be true: > window.parent.navigator.userActivation < UserActivation {hasBeenActive: true, isActive: false} > window.navigator.userActivation < UserActivation {hasBeenActive: false, isActive: false} It seems we may just have a bug in how we calculate User Activation. I’d recommend filing one on bugs.webkit.org for us to investigate. -Jer > On Oct 24, 2024, at 10:54 AM, iosdeveloper (premier.one) via webkit-help > <[email protected]> wrote: > > Dear WebKit Team, > > I am writing to seek your assistance with a persistent issue we've been > facing with Safari's autoplay policy for cross-origin video content. > > Our Issue: > We have been struggling with Safari's default behavior of muting autoplay > video content when the media is hosted on a different domain than the main > website.
