Python VLC 模块在没有标签的情况下不工作

Question

我正在使用 Python 中的 VLC 模块来播放一些通过 YouTube 到 MP3 转换器下载的音乐，用于一个项目。问题是，我发现这些文件不喜欢合作，Python 最终向我扔了一大堆红色。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，它会向我抛出错误。这是我的代码：

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")

这是输出“非常长...”：

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.

还有比这更多的错误，但是 Stack Overflow 限制我把它们都放出来。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.

这里是下载器，如果需要的话：

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")

我已经在我的机器上尝试了你的代码，它可以工作。我认为您使用的是过时的版本或过时的库。所以试试下面的代码，如果你找到更可靠的解决方案，请告诉我......

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