推荐答案
截至2019年6月:
1.获取静态缩略图非常简单
- 它们通过YouTube API公开，甚至更好，它们遵循非常简单统一的URL结构(更多详细信息 2.有限数量的浏览器支持Youtube的动画缩略图. .
- Apparently, desktop browsers Chrome and Opera (source)
- The thumbnails, btw, are in WebP image format, which has a wider browser support.
3.为有限数量的视频获取动画缩略图是相对容易的.
例如，您可以在浏览器开发工具中检查网络活动(有关 Chrome ).
You can, for example, inspect the network activity in your browser dev tools (more details for Chrome).
在网络面板打开的情况下，访问包含所需视频的页面列表，清除网络活动(您也可以选择"Img"以仅显示与图像有关的活动)，然后将鼠标悬停在所需视频上.然后，只需右键单击所需的资源并复制网址即可.
With the network panel open, visit a page listing that includes the desired video, clear the network activity (you can also select 'Img' to display only activity related to images) and hover the desired video. Then just right click on the desired resource and copy the url.

4.据我所知，目前尚无法以编程方式(没有网络抓取)获取动画缩略图
- 换句话说，给定视频ID，当前无法通过API或定义的URL模式获得动画缩略图URL.
PS ::希望有人能证明我在第4点上错了，以下是这些URL的一些示例:
PS.: Hoping that somebody can prove me wrong on point #4, here are a few examples of those URLs:
https://i.ytimg.com/an_webp/zdOmNiXvM3w/mqdefault_6s.webp?du=3000&sqp=CPDloOgF&rs=AOn4CLD9rYflZAMK6qBIbYJDoQZLk9UARw
