youtube - iframe 嵌入代码中 YouTube "-nocookie: and "rel=0"的含义

Question

如果我从 YouTube 视频中复制嵌入代码，则会得到以下代码。

<iframe width="560" height="315" src="//www.youtube.com/embed/kk5xfK0ovrk" frameborder="0" allowfullscreen></iframe>

如果我为视频选择 1280x760 大小并复制该嵌入代码，我会得到:

<iframe width="1280" height="720" src="//www.youtube-nocookie.com/embed/kk5xfK0ovrk?rel=0" frameborder="0" allowfullscreen></iframe>

但是如果我只使用原始嵌入代码并且只将宽度更改为 1280 并将高度更改为 720，我也会得到一个完美的 1280x760 视频。所以我想知道 YouTube 为 1280x560 案例生成的代码中的“-nocookie”和“rel=0”的目的是什么。

谢谢

YouTube 的新“nocookie”功能和引自 Youtube's Rel=0文档:

rel (supported players: AS3, AS2, HTML5) Values: 0 or 1. Default is 1. This parameter indicates whether the player should show related videos when playback of the initial video ends.

But after 25 September 2018, you will not be able to disable related videos. Instead, if the rel parameter is set to 0, related videos will come from the same channel as the video that was just played.
