是否有任何文档可以将youtube-dl用作项目中的python库？
我知道我可以使用主类，但我找不到任何文档或示例...
import youtube_dl
ydl = youtube_dl.YoutubeDL(params)
... ?

如果您从github下载版本，则可以生成适用于开发的sphinx-docs。然后使用pythons帮助函数通常会让人知道函数的用途是什么
>>> import youtube_dl as yt
>>> help(yt)
此外，我发现ipython是一个使用%edit魔法探索代码的有用工具。
%edit yt.main
会直接带您到main函数的源代码。

关于嵌入youtube-dl的official documentation now contains a section。你正走在正确的轨道上;
import youtube_dl
with youtube_dl.YoutubeDL({}) as ydl:
ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
是一个很好的最小程序。

类似的问题：How to use youtube-dl from a python program
在来源中检查此文件：https://github.com/rg3/youtube-dl/blob/master/youtube_dl/__init__.py
您需要选项dict（最初使用从命令行接收的参数生成）：
ydl_opts = {
'usenetrc': opts.usenetrc,
'username': opts.username,
'password': opts.password,
# ... all options list available in sources
'exec_cmd': opts.exec_cmd,
}
然后创建YoutubeDL实例并使用自描述的名称调用一些方法：
with YoutubeDL(ydl_opts) as ydl:
ydl.print_debug_header()
ydl.add_default_info_extractors()
# PostProcessors
# Add the metadata pp first, the other pps will copy it
if opts.addmetadata:
ydl.add_post_processor(FFmpegMetadataPP())
if opts.extractaudio:
ydl.add_post_processor(FFmpegExtractAudioPP(preferredcodec=opts.audioformat, preferredquality=opts.audioquality, nopostoverwrites=opts.nopostoverwrites))
if opts.recodevideo:
ydl.add_post_processor(FFmpegVideoConvertor(preferedformat=opts.recodevideo))
if opts.embedsubtitles:
ydl.add_post_processor(FFmpegEmbedSubtitlePP(subtitlesformat=opts.subtitlesformat))
if opts.xattrs:
ydl.add_post_processor(XAttrMetadataPP())
if opts.embedthumbnail:
if not opts.addmetadata:
ydl.add_post_processor(FFmpegAudioFixPP())
ydl.add_post_processor(AtomicParsleyPP())
# Please keep ExecAfterDownload towards the bottom as it allows the user to modify the final file in any way.
# So if the user is able to remove the file before your postprocessor runs it might cause a few problems.
if opts.exec_cmd:
ydl.add_post_processor(ExecAfterDownloadPP(
verboseOutput=opts.verbose, exec_cmd=opts.exec_cmd))
# Update version
if opts.update_self:
update_self(ydl.to_screen, opts.verbose)
# Remove cache dir
if opts.rm_cachedir:
ydl.cache.remove()
# Maybe do nothing
if (len(all_urls) < 1) and (opts.load_info_filename is None):
if not (opts.update_self or opts.rm_cachedir):
parser.error(u'you must provide at least one URL')
else:
sys.exit()
try:
if opts.load_info_filename is not None:
retcode = ydl.download_with_info_file(opts.load_info_filename)
else:
retcode = ydl.download(all_urls)
except MaxDownloadsReached:
ydl.to_screen(u'--max-download limit reached, aborting.')
retcode = 101
