--version                        Print program version and exit
-U, --update                     Update this program to latest version. Make

                                 skip unavailable videos in a playlist

                                 playlist or the command line) if an error
                                 occurs

                                 apple". Use the value "auto" to let

                                 repairs broken URLs, but emits an error if

输出模板

-o选项允许用户指示输出文件名的模板。

tl; dr: 导航我的例子

下载单个文件时的基本用法是不设置任何模板参数,例如youtube-dl -o funny_video.flv "https://some/video"。但是,它可能包含在下载每个视频时将被替换的特殊序列。可以根据python字符串格式化操作来格式化特殊序列。例如,%(NAME)s%(NAME)05d。为了澄清,这是一个百分号,后跟括号中的名称,后跟格式化操作。允许的名称和序列类型是:

当在输出模板中引用时,每个上述序列将被对应于序列名称的实际值替换。请注意,某些序列不能保证存在,因为它们依赖于特定提取器获得的元数据。这些序列将被替换NA

例如,对于-o %(title)s-%(id)s.%(ext)s带有标题youtube-dl test video和id 的mp4视频BaW_jenozKcj,这将导致在youtube-dl test video-BaW_jenozKcj.mp4当前目录中创建一个文件。

对于数字序列,您可以使用与数字相关的格式,例如,%(view_count)05d将生成一个字符串,其中视图计数用零填充,最多5个字符,如00042

输出模板还可以包含任意分层路径,例如-o '%(playlist)s/%(playlist_index)s - %(title)s.%(ext)s',这将导致下载与该路径模板相对应的目录中的每个视频。将自动为您创建任何缺少的目录。

要在输出模板中使用百分比文字,请使用%%。输出到stdout使用-o -

当前的默认模板是%(title)s-%(id)s.%(ext)s

在某些情况下,您不需要特殊字符,例如中,空格或&,例如将下载的文件名传输到Windows系统或通过8位不安全的通道传输文件名。在这些情况下,添加--restrict-filenames标志以获得更短的标题:

输出模板和Windows批处理文件

如果您在Windows批处理文件中使用输出模板,则必须%通过加倍来转义普通百分比字符(),这样-o "%(title)s-%(id)s.%(ext)s"才能成为-o "%%(title)s-%%(id)s.%%(ext)s"。但是你不应该触摸%不是普通字符的,例如扩展的环境变量应保持不变:-o "C:\%HOMEPATH%\Desktop\%%(title)s.%%(ext)s"

输出模板示例

请注意,在Windows上,您可能需要使用双引号而不是单引号。

格式选择

默认情况下,youtube-dl会尝试下载最佳可用质量,即如果你想要最好的质量,你不需要传递任何特殊选项,youtube-dl 默认会为你猜测。

但有时您可能希望以不同的格式下载,例如当您处于慢速或间歇性连接时。实现这一目标的关键机制是所谓的格式选择,您可以根据该格式明确指定所需的格式,根据某些标准或标准选择格式,设置优先级等等。

格式选择的一般语法是--format FORMAT或更短-f FORMAT,其中FORMAT选择器表达式,即描述您要下载的格式或格式的表达式。

tl; dr: 导航我的例子

最简单的情况是请求特定格式,例如,-f 22您可以下载格式代码等于22的格式。您可以使用--list-formats或获取特定视频的可用格式代码列表-F。请注意,这些格式代码是特定于提取器的。

你也可以使用一个文件扩展名(目前3gpaacflvm4amp3mp4oggwavwebm都支持),下载特定文件扩展名担任一个单一的文件,如质量最好的格式,-f webm将下载与最优质的格式webm扩展名担任了单个文件。

您还可以使用特殊名称来选择特定的边缘大小写格式:

  • best:选择具有视频和音频的单个文件所代表的最佳质量格式。
  • worst:选择具有视频和音频的单个文件所代表的最差质量格式。
  • bestvideo:选择最佳质量的仅视频格式(例如DASH视频)。可能无法使用。
  • worstvideo:选择质量最差的纯视频格式。可能无法使用。
  • bestaudio:选择质量最佳的音频格式。可能无法使用。
  • worstaudio:选择质量最差的音频格式。可能无法使用。

例如,要下载可以使用的最差质量视频格式-f worstvideo

如果您要下载多个视频并且它们没有相同的格式,您可以使用斜杠指定首选项顺序。请注意,斜杠是左关联的,即左侧的格式是首选,例如,-f 22/17/18如果可用则下载格式22,否则它将下载格式17(如果可用),否则它将下载格式18(如果可用),否则它会抱怨没有合适的格式可供下载。

如果您想下载同一视频的多种格式,请使用逗号作为分隔符,例如-f 22,17,18,如果它们可用,将下载所有这三种格式。或者更复杂的例子与优先功能相结合:-f 136/137/mp4/bestvideo,140/m4a/bestaudio

您还可以通过将条件放在括号中来过滤视频格式,如-f "best[height=720]"(或-f "[filesize>10M]")中所示。

下面的数值元字段可以用比较使用<<=>>==(等于), !=(未等于):

  • filesize:字节数,如果事先知道的话
  • width:视频宽度(如果已知)
  • height:视频的高度,如果已知
  • tbr:以KBit / s为单位的音频和视频的平均比特率
  • abr:平均音频比特率(KBit / s)
  • vbr:平均视频比特率(KBit / s)
  • asr:以赫兹为单位的音频采样率
  • fps:帧率

还过滤比较=(等于),^=(开头),$=(结束),*=(包含)和跟随字符串元字段的工作:

  • ext: 文件扩展名
  • acodec:正在使用的音频编解码器的名称
  • vcodec:正在使用的视频编解码器的名称
  • container:容器格式的名称
  • protocol:将被用于实际下载协议,小写(httphttpsrtsprtmprtmpemmsf4mismhttp_dash_segmentsm3u8,或m3u8_native
  • format_id:格式的简短描述

任何字符串比较都可以以否定为前缀,!以产生相反的比较,例如!*=(不包含)。

注意,保证上述元字段都不存在,因为这仅取决于由特定提取器获得的元数据,即视频主机提供的元数据。

除非您?在运算符后面添加问号(),否则将排除值未知的格式。您可以组合格式过滤器,因此-f "[height <=? 720][tbr>500]"选择最多720p视频(或高度未知的视频),比特率至少为500 KBit / s。

您可以使用-f <video-format>+<audio-format>(需要安装ffmpeg或avconv)-f bestvideo+bestaudio将两种格式的视频和音频合并为一个文件,例如,将下载最佳的纯视频格式,最佳纯音频格式,并将它们与ffmpeg / avconv一起复用。

格式选择器也可以使用括号进行分组,例如,如果要下载高度低于480的最佳mp4和webm格式,则可以使用-f '(mp4,webm)[height<480]'

自2015年4月底和版本2015.04.26起,youtube-dl将使用-f bestvideo+bestaudio/best默认格式选择(请参阅#5447#5456)。如果安装了ffmpeg或avconv,则会导致下载bestvideobestaudio单独下载并将它们复合到一个文件中,从而提供最佳的整体质量。否则它会回退best并导致下载作为单个文件提供的最佳可用质量。best对于不是来自YouTube的视频也需要,因为它们不提供两个不同文件中的音频和视频。如果您只想下载一些DASH格式(例如,如果您对获取分辨率高于1080p的视频不感兴趣),可以添加-f bestvideo[height<=?1080]+bestaudio/best到您的配置文件。请注意,如果您使用youtube-dl流式传输stdout(并且最有可能将其传输到您的媒体播放器),即您明确指定输出模板为-o -,youtube-dl仍然使用-f best格式选择,以便立即开始向播放器传送内容而不是等到,bestvideobestaudio下载和多路复用。

如果您想保留旧的格式选择行为(在youtube-dl 2015.04.26之前),即您希望下载作为单个文件提供的最佳可用质量媒体,则应明确指定您的选择-f best。您可能希望将其添加到配置文件中,以便每次运行youtube-dl时都不键入它。

格式选择示例

请注意,在Windows上,您可能需要使用双引号而不是单引号。

# Download best mp4 format available or any other best if no mp4 available
$ youtube-dl -f 'bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best'

# Download best format available but no better than 480p
$ youtube-dl -f 'bestvideo[height<=480]+bestaudio/best[height<=480]'

# Download best video only format but no bigger than 50 MB
$ youtube-dl -f 'best[filesize<50M]'

# Download best format available via direct link over HTTP/HTTPS protocol
$ youtube-dl -f '(bestvideo+bestaudio/best)[protocol^=http]'

# Download the best video format and the best audio format without merging them
$ youtube-dl -f 'bestvideo,bestaudio' -o '%(title)s.f%(format_id)s.%(ext)s'

 

请注意,在最后一个示例中,建议输出模板作为bestvideo,bestaudio可能具有相同的文件名。

视频选择

可以使用选项按照上传日期过滤视频--date--datebefore--dateafter。他们接受两种格式的日期:

  • 绝对日期:格式的日期YYYYMMDD
  • 相对日期:格式的日期 (now|today)[+-][0-9](day|week|month|year)(s)?

例子:

#仅下载过去6个月内上传的视频 
$ youtube-dl --dateafter now-6months#仅下载1970年1月1日上传的视频 
$ youtube-dl  - 日期19700101
$#仅下载200x上传的视频十年 
$ youtube-dl --dateafter 20000101 --datebefore 20091231
