Python的VLC模塊不工作，沒有標籤

Question

我在Python中使用VLC模塊來播放一些音樂下載與YouTube到MP3轉換器的項目。問題是，我發現這些文件不喜歡合作，python最終會對我產生負面影響。我相信這是因爲mp3文件沒有標籤，所以當模塊檢查它們並且它們不存在時，它會向我發出錯誤。這裏是我的代碼：

import vlc 
import os 
import time 

def playtrack(fileid, songname): 
    filename = fileid + ".mp3" 
    print('Now playing: ' + songname) 
    music = vlc.MediaPlayer(filename) 
    music.play() 
    print(music.get_state()) 
    time.sleep(60) 
    print("Finished.") 
    #os.remove(filename) 

playtrack("tVj0ZTS4WF4", "foo") 

這裏是輸出「很長......」：

Now playing: foo 
State.NothingSpecial 
Warning: option --plugin-path no longer exists. 
Warning: option --plugin-path no longer exists. 
TagLib: MPEG::Header::parse() -- The next frame was not consistent with this frame. 
TagLib: MPEG::Header::parse() -- The next frame was not consistent with this frame. 

沒有比這種方式更多的錯誤，但StackOverflow上限制了我從把他們所有。無論如何，它們都是一樣的。

TagLib: MPEG::Header::parse() -- The next frame was not consistent with this 
TagLib: MPEG::Header::parse() -- Invalid MPEG version bits. 
TagLib: MPEG::Header::parse() -- Invalid MPEG layer bits. 
TagLib: MPEG::Header::parse() -- Invalid MPEG version bits. 
TagLib: MPEG::Header::parse() -- Invalid bit rate. 
TagLib: MPEG::Header::parse() -- Invalid MPEG version bits. 
TagLib: MPEG::Header::parse() -- The next frame was not consistent with this frame. 
TagLib: MPEG::Header::parse() -- Invalid bit rate. 
TagLib: MPEG::Header::parse() -- Could not read the next frame header. 
TagLib: MPEG::Header::parse() -- The next frame was not consistent with this frame. 
TagLib: MPEG::Properties::read() -- Could not find a valid first MPEG frame in the stream. 
Finished.

這裏的下載，如果有必要：

import youtube_dl 
import os 


class InvalidURL(Exception): 
    pass 


class SongExists(Exception): 
    pass 


def download(url): 
    try: 
     options = { 
      'format': 'bestaudio/best', 
      'extractaudio': True, # only keep the audio 
      'audioformat': "mp3", # convert to wav 
      'outtmpl': '%(id)s.mp3', # name the file the ID of the video 
      'noplaylist': True, # only download single song, not playlist 
     } 
     with youtube_dl.YoutubeDL(options) as ydl: 
      r = ydl.extract_info(url, download=False) 
      if os.path.isfile(str(r["id"])): 
       raise SongExists('This song has already been requested.') 
      print("Downloading" + str(r["title"])) 
      ydl.download([url]) 
      print("Downloaded" + str(r["title"])) 
      return r["title"], r["id"] 
    except youtube_dl.utils.DownloadError: 
     raise InvalidURL('This URL is invalid.') 

if __name__ == "__main__": 
    download("https://www.youtube.com/watch?v=tVj0ZTS4WF4")

我已經試過我的機器上的代碼和它的作品。我認爲你正在使用過時的版本或過時的庫。所以請嘗試在下面的代碼，並讓我知道如果你找出一個更可靠的解決方案....

sudo pip uninstall vlc 
sudo pip uninstall python-vlc 
sudo pip install python-vlc
