html - YouTube 和 Twitch 如何覆盖带音频视频的自动播放政策？

Question

我知道谷歌浏览器有一个自动播放政策，不能自动播放带音频的视频。像 YouTube 和 Twich 这样的网站怎么能绕过这个？他们如何自动播放带音频的视频？

Answer 1

看起来他们被特别列入白名单。

Chrome does this by learning your preferences. If you don’t havebrowsing history, Chrome allows autoplay for over 1,000 sites where wesee that the highest percentage of visitors play media with sound. Asyou browse the web, that list changes as Chrome learns and enablesautoplay on sites where you play media with sound during most of yourvisits, and disables it on sites where you don’t. This way, Chromegives you a personalized, predictable browsing experience.
