Would the ideal solution be allowing playback of multiple videos with added support for the IntersectionObserver API, making it possible for players to autoplay all videos or just the one that has the greatest intersection with the viewport?

That would allow the page to control autoplaying-only-when-visible manually, which I'm sure many page authors are interested in. But the baseline behavior (<video autoplay> should play when visible) should "just work" once the related "multiple autoplaying videos" bug is fixed. Agreed. Is there a timeline set for a fix that we can share with our publishers? |
