Feature-Policy: autoplay
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The HTTP Feature-Policy
header
autoplay
directive controls whether the current document is allowed to
autoplay media requested through the HTMLMediaElement
interface.
When this policy is enabled 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.
For more details on autoplay and autoplay blocking, see the article Autoplay guide for media and Web Audio APIs.
