开发者模式使用
youtube_dl在python代码中使用方式
from __future__ import unicode_literals ## for python2
import youtube_dl
ydl_opts = {}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download(['http://www.youtube.com/watch?v=BaW_jenozKc'])
ydl_opts 配置可以在YoutubeDL.py中找到,for example
ydl_opts = {
##Download best format available but not better that 720p
'format': 'bestvideo[height<=720]+worstaudio[ext=m4a]/best[height<=720][ext=mp4]',
'merge_output_format': 'mp4',
'outtmpl': './download/%(title)s.%(ext)s',
# # 'postprocessors': [{
# # 'key': 'FFmpegExtractAudio',
# # 'preferredcodec': 'mp3',
# # 'preferredquality': '192',
# # }],
# # 'logger': MyLogger(),
# #'progress_hooks': [my_hook],
