youtube 4k 视频未从 youtube 列出 api

Question

当我尝试使用 youtube 的 4k 视频时，我总是无法获得如此高分辨率的流。最高分辨率为高清。

例如：

https://www.youtube.com/watch?v=tdwbYGe8pv8

我只能得到以下资料：

----> 22/1280x720/9/0/115
----> 43/640x360/99/0/0
----> 18/640x360/9/0/115
----> 5/426x240/7/0/0
----> 36/426x240/99/1/0
----> 17/256x144/99/1/0

这意味着最高分辨率是 1280x720 但不是 4k 视频。

有人知道这是否真的是个问题，或者我需要使用其他 API 来获取 4k 视频吗？

Answer 1

<...> 1080p support is gone - youtube removed 1080p downloads, only DASH would work - and we need a other way to get 1080p and above.

Answer 2

一个可能的解决方案：

安装 youtube-dl 工具

brew 安装 youtube-dl
运行查询流信息的命令如下：

youtube-dl -F http://www.youtube.com/watch?v=TMwpbfxY_Gc --verbose

输出：

运行下面的命令下载视频 (138) 和音频 (141)

youtube-dl -f 138+141 https://www.youtube.com/watch?v=iNJdPyoqt8U

然后您将获得 4k 视频文件。
