如何从 python 程序使用 youtube-dl? [英] How to use youtube-dl from a python program?

问题描述

我想访问以下shell命令的结果，

I would like to access the result of the following shell command,

youtube-dl -g "www.youtube.com/..."

从python程序中将其输出direct url打印到文件中.这是我尝试过的:

to print its output direct url to a file, from within a python program. This is what I have tried:

import youtube-dl
fromurl="www.youtube.com/..."
geturl=youtube-dl.magiclyextracturlfromurl(fromurl)

这可能吗?我试图了解源代码中的机制但迷路了:youtube_dl/__init__.py、youtube_dl/youtube_DL.py、info_extractors ...

Is that possible? I tried to understand the mechanism in the source but got lost: youtube_dl/__init__.py, youtube_dl/youtube_DL.py, info_extractors ...

推荐答案

这并不困难 实际记录:

import youtube_dl

ydl = youtube_dl.YoutubeDL({'outtmpl': '%(id)s.%(ext)s'})

with ydl:
    result = ydl.extract_info(
        'http://www.youtube.com/watch?v=BaW_jenozKc',
        download=False # We just want to extract the info
    )

if 'entries' in result:
    # Can be a playlist or a list of videos
    video = result['entries'][0]
else:
    # Just a video
    video = result

print(video)
video_url = video['url']
print(video_url)
