我正在尝试使用this script使用Python下载YouTube视频.

目前我使用如下

youtube-dl "http://www.youtube.com/watch?v=dvsdgyuv"

在他们编写的文档中我可以使用这些文档

id: The sequence will be replaced by the video identifier.
url: The sequence will be replaced by the video URL.
uploader: The sequence will be replaced by the nickname of the person who uploaded the video.
upload_date: The sequence will be replaced by the upload date in YYYYMMDD format.
title: The sequence will be replaced by the literal video title.
stitle: The sequence will be replaced by a simplified video title, restricted to alphanumeric characters and dashes.
ext: The sequence will be replaced by the appropriate extension (like flv or mp4).
epoch: The sequence will be replaced by the Unix epoch when creating the file.
autonumber: The sequence will be replaced by a five-digit number that will be increased with each download, starting at zero.`enter code here`

他们还没有写过如何使用它.

如何使用视频文件名与标题相同？

他们告诉使用它,但我不知道如何在命令行中使用它.

%(title)s-%(id)s.%(ext)s.

解决方法:

在文档的底部,它说明了如何：

The -o option allows users to
indicate a template for the output
file names. The basic usage is not
to set any template arguments when
downloading a single file, like in
youtube-dl -o funny_video.flv
“http://some/video”. However, it may
contain special sequences that will be
replaced when downloading each video.
The special sequences have the format %(NAME)s. To clarify, that’s
a percent symbol followed by a name in
parenthesis, followed by a lowercase
S. Allowed names are: …

您可以像这样运行命令以使用这些特殊输出参数：

youtube-dl "http://www.youtube.com/watch?v=dvsdgyuv" -o "%(title)s-%(id)s.%(ext)s."
