指定用于下载播放列表的视频格式(S)

Question

我正在尝试下载bestaudo+bestvideo质量的youtube播放列表。它下载了第一个视频，但对于第二个视频，它抛出了错误ERROR: requested format not available。

问题：

如果无法获得通过的质量，如何使youtube-dl获取其他质量的第二段视频？

首先我发布了这个命令

youtube-dl -f bestaudio+bestvideo "https://www.youtube.com/playlist?list=PLvwB65U8V0HHCEyW2UTyOJym5FsdqfbHQ"
[youtube:playlist] PLvwB65U8V0HHCEyW2UTyOJym5FsdqfbHQ: Downloading webpage

ERROR: The first format must contain the video, try using "-f 136+141"

然后

Answer 1

如第一条错误消息所述：

错误:第一种格式必须包含视频

所以应该是-f bestvideo+bestaudio而不是-f bestaudio+bestvideo。此外，您不需要指定任何格式在所有-最好的质量将自动下载默认。
