YouTube 和 Twitch 如何覆盖带音频视频的自动播放策

问题描述

我知道 Google Chrome 有一项自动播放政策，即无法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?

I know that Google Chrome has an autoplay policy where videos with audio cannot be autoplayed. How come websites like YouTube and Twich are able to bypass this? How can they autoplay videos with audio?

推荐答案

看起来他们被特别列入白名单.

It looks like they're specially white-listed.

Chrome 通过了解您的偏好来做到这一点.如果你没有浏览历史记录，Chrome 允许自动播放超过 1,000 个网站看到最高比例的访问者播放有声媒体.作为您浏览网络时，该列表会随着 Chrome 的学习和启用而改变在您大部分时间播放有声媒体的网站上自动播放访问，并在您不访问的网站上禁用它.这样，Chrome为您提供个性化、可预测的浏览体验.

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