如何将附加参数传递给 youtube-dl 的函数 `my_hook`

Question

import youtube_dl
def my_hook(d,`some parameter`):
    ...
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
   ydl.download("link" , 'some parameter')

如何将

some parameter

传递给

my_hook

函数？我想将套接字对象传递给

my_hook

函数，以向另一台机器报告最新的下载进度。怎么才能通过呢？

Answer 1

#! /usr/bin/env python3
import youtube_dl

def progress_hook( response ):
    ##  send  response['status']  to whatever subprocess you have going on.
    print( response['status'] )

ydl_opts = {
    'progress_hooks': [progress_hook],
    ##  other options, resolution & whatnot
}

link = 'm.youtube.com/watch?v=dQw4w9WgXcQ'

with youtube_dl .YoutubeDL( ydl_opts ) as ydl:
    ##  metadata = ydl .extract_info( link, download=False )
    ##  print( metadata )
    ydl .download( [link, ydl_opts] )

Answer 2

导入 youtube_dl defwrapper_hook(custom_param): def my_hook(d,

some parameter

): ... 将 youtube_dl.YoutubeDL(ydl_opts) 用作 ydl： ydl.download("链接" , '某个参数')
