Permissions-Policy: autoplay

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTTP Permissions-Policy header autoplay directive controls whether the current document is allowed to autoplay media requested through the HTMLMediaElement interface.

Specifically, where a defined policy blocks use of this feature and there were no user gestures, the Promise returned by HTMLMediaElement.play() will reject with a DOMException. The autoplay attribute on <audio> and <video> elements will be ignored.

Note: For more details on autoplay and autoplay blocking, see the article Autoplay guide for media and Web Audio APIs.
