如何从python程序使用youtube-dl？

这并不困难，实际上已记录在案：

import youtube_dlydl = 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 = resultprint(video)video_url = video['url']print(video_url)
