Youtube-dl订阅mp3

如何解决Youtube-dl订阅mp3

所以我的目标是编写代码，以便它将其从我所有订阅的Youtube频道中自动下载到mp3文件中。 我在处理EO error时遇到了困难，这对我来说并不很清楚，因此我从来不必处理它，我已经做过研究，但是没有什么可以帮我的忙，所以代码如下：

import opml
import feedparser
import youtube_dl
from glob import glob
from pprint import pprint

from time import time,mktime,strptime
from datetime import datetime

if len(glob('last.txt')) == 0:
    f = open ('last.txt','w')
    f.write(str(time()))
    print('Initialized last.txt file for timestamp')
    f.close()
else:
    f = open('last.txt','r')
    content = f.read()
    f.close()
    
    outline = opml.parse('subs.xml')
    
    ptime = datetime.utcfromtimestamp(float(content))
    ftime = time()
    urls = []
    for i in range(0,len(outline[0])):
        urls.append(outline[0][i].xmlUrl)
    print(urls)
    
    videos = []
    for i in range(0,len(urls)):
        print('Parsing through channel '+str(i+1)+' out of '+str(len(urls)),end='\r')
        feed = feedparser.parse(urls[i])
        for j in range(0,len(feed['items'])):
            timef = feed['items'][j]['published_parsed']
            dt = datetime.fromtimestamp(mktime(timef))
            if dt > ptime:
                videos.append(feed['items'][j]['link'])
                
    if len(videos) == 0:
        print('Sorry,no new video found')
    else:
        print(str(len(videos))+' bew vudeis found')
        
    ydl_options = {
            'ignoreerrors' : True,'format': 'bestaudio[filesize<30]','keepvideo': False,'outtmpl': 'filename','postprocessors': [{
                    'key': 'FFmpegExtractAudio','audioquality': '0','preferredquality': '320',}]
    }
     
    with youtube_dl.YoutubeDL(ydl_options) as ydl:
        ydl.download(videos)
        

我尝试了新的YoutubeManager subs.xml，尝试了其他具有不同渠道的Youtube帐户，而他们的subs.xml没有帮助。

这是我的错误输出

解决方法

该错误表明您无权访问该文件。
如果我在PC上运行print(opml.parse('subs.xml'))，则会收到完全相同的错误消息。 路径错误或者您没有对该文件的读取权限。

代码的设置方式意味着python在运行.py文件的路径中查找该文件。
subs.xml与python文件位于同一文件夹中吗？
您可以尝试的一种方法是像这样直接链接路径：
outline = opml.parse(r'C:\folder_name\subs.xml')
