To all interested:
致所有感兴趣的人：
The "Coding for fun"book's chapter 4 "InnerTube: Download, Convert, and Sync YouTube Videos"deals with the topic. The code and discussion are at http://www.c4fbook.com/InnerTube.
“为乐趣而编码”一书的第 4 章“InnerTube：下载、转换和同步 YouTube 视频”涉及该主题。代码和讨论位于http://www.c4fbook.com/InnerTube。
[PLEASE BEWARE] While the overall concepts are valid some years after the publication, non-documented details of the youtubeinternals the project relies on can have changed (see the comment at the bottom of the page behind the second link).
[请注意] 虽然整体概念在发布几年后仍然有效，但项目所依赖的youtube内部结构的未记录细节可能已更改（请参阅页面底部第二个链接后面的评论）。

Gonna give another answer, since the libraries mentioned haven't been actively developed anymore.
将给出另一个答案，因为提到的库不再被积极开发。
Consider using YoutubeExplode. It has a very rich and consistent API and allows you to do a lot of other things with youtube videos beside downloading them.
考虑使用YoutubeExplode。它具有非常丰富且一致的 API，除了下载 YouTube 视频外，它还允许您对 YouTube 视频执行许多其他操作。

I suggest you look into SharpGrabber- a .NET Standard library written just for this purpose. It is newer than YouTubeExtractor and libvideo.
It supports YouTubeand Instagramas the time of this answer. This project also offers high-quality video and audio mixing and a cross-platform desktop application.
我建议您查看SharpGrabber- 一个专门为此目的编写的 .NET Standard 库。它比 YouTubeExtractor 和 libvideo 更新。它支持YouTube并Instagram作为此答案的时间。该项目还提供高质量的视频和音频混合以及跨平台的桌面应用程序。
