来自官方 Apple WebKit 文档 (iOS):

Starting in iOS 10, WebKit relaxes its inline and autoplay policies to make these presentations possible, but still keeps in mind sites’ bandwidth and users’ batteries.

By default, WebKit will have the following policies:

• video elements will be allowed to autoplay without a user gesture if their source media contains no audio tracks.
• video muted elements will also be allowed to autoplay without a user gesture. If a element gains an audio track or becomes un-muted without a user gesture, playback will pause.

至于移动 Chrome (Android):

Muted autoplay for video is supported by Chrome for Android as of version 53. Playback will start automatically for a video element once it comes into view if both autoplay and muted are set, and playback of muted videos can be initiated progamatically with play(). Previously, playback on mobile had to be initiated by a user gesture, regardless of the muted state.

例子:

 <video id="myVideo"muted defaultMuted autoplay playsinline controls>
     <source src="myVideo.mp4" type="video/mp4">
 </video>
