使用youtube-dl的wrting python脚本只提取下载链接？

Question

我是python的新手,我正在编写一个python脚本,使用youtube-dl只提取下载链接,就像控制台给出的链接一样(youtube-dl --get-url url).我不想下载媒体,我只需要从我的脚本中下载链接.

Answer 1

>>> from youtube_dl import YoutubeDL # $ pip install youtube-dl
>>> url = 'https://www.youtube.com/watch?v=pvAsqPbz9Ro'
>>> ydl = YoutubeDL()
>>> r = ydl.extract_info(url, download=False)
[youtube] pvAsqPbz9Ro: Downloading webpage
[youtube] pvAsqPbz9Ro: Downloading video info webpage
[youtube] pvAsqPbz9Ro: Extracting video information
[youtube] pvAsqPbz9Ro: Downloading DASH manifest
[youtube] pvAsqPbz9Ro: Downloading DASH manifest
>>> r['url']
u'https://r6---sn-n8v7zne7.googlevideo.com/videoplayback?...&ipbits=0'

如果有多种媒体格式,那么获取最后一种格式的媒体网址:

with youtube_dl.YoutubeDL(dict(forceurl=True)) as ydl:
    r = ydl.extract_info(url, download=False)
    media_url = r['formats'][-1]['url']
