Python的VLC模块不工作，没有标签

Question

我在Python中使用VLC模块来播放一些音乐下载与YouTube到MP3转换器的项目。问题是，我发现这些文件不喜欢合作，python最终会对我产生负面影响。我相信这是因为mp3文件没有标签，所以当模块检查它们并且它们不存在时，它会向我发出错误。这里是我的代码：

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") 

这里是输出“很长......”：

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. 

没有比这种方式更多的错误，但StackOverflow上限制了我从把他们所有。无论如何，它们都是一样的。

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() -- The next frame was not consistent with this frame.

Finished.

这里的下载，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")

我已经试过我的机器上的代码和它的作品。我认为你正在使用过时的版本或过时的库。所以请尝试在下面的代码，并让我知道如果你找出一个更可靠的解决方案....

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