How to use youtube-dl from a python program
提问by JulienFr
I would like to access the result of the shell command:
我想访问 shell 命令的结果：
youtube-dl -g "www.youtube.com..."
to print its output direct urlto file; from within a python program:
将其输出打印direct url到文件；从 python 程序中：
import youtube-dl
fromurl="www.youtube.com ...."
geturl=youtube-dl.magiclyextracturlfromurl(fromurl)
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...
那可能吗 ？我试图了解源的机制，但迷路了：youtube_dl/__init__.py，youtube_dl/youtube_DL.py，info_extractors...

It's not difficult and actually documented:
这并不困难，而且实际记录在案：
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)

If youtube-dlis a terminal program, you can use the subprocessmodule to access the data you want.
如果youtube-dl是终端程序，则可以使用该subprocess模块访问您想要的数据。

Here is a way.
这是一种方法。
We set-up options' string, in a list, just as we set-up command line arguments. In this case opts=['-g', 'videoID']. Then, invoke youtube_dl.main(opts). In this way, we write our custom .py module, import youtube_dland then invoke the main()function.
我们在列表中设置选项的字符串，就像我们设置命令行参数一样。在这种情况下opts=['-g', 'videoID']。然后，调用youtube_dl.main(opts). 这样，我们编写自定义的 .py 模块，import youtube_dl然后调用该main()函数。
