javascript - 2020 : iOS Safari Video Autoplay Options?

Question

到目前为止，我所有的研究和努力都在这方面碰壁:目前有什么方法可以让视频在 iOS 的 Safari 上自动播放吗？

有些人提到了视频转码或使用 playsinline(适用于 Android)，但对 iOS/Safari 没有任何效果。

Answer 1

我相信以下仍然是 iOS 的当前图片:

elements will now honor the autoplay attribute, for elements which meet the following conditions:

• elements will be allowed to autoplay without a user gesture if their source media contains no audio tracks.
• 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.
• elements will only begin playing when visible on-screen such as when they are scrolled into the viewport, made visible through CSS, and inserted into the DOM.
• elements will pause if they become non-visible, such as by being scrolled out of the viewport.

这还要求视频元素具有“playsinline”属性。

因此支持自动播放视频，但功能有限，可能无法满足您的特定需求。

另外一个注意事项 - 如果您的用例是针对 WebView 而不是常规浏览器，那么您将拥有更多控制权。请在此处查看“wkwebviewconfiguration”的文档，尤其是“mediaTypesRequiringUserActionForPlayback”:
