VLC python模块在Ubuntu中不工作

我有这样的代码

import vlc                      # no error
Instance = vlc.Instance()       # no error
MediaPlayer = Instance.media_player_new()  # error triggered  here

错误消息是

Instance.media_player_new()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "vlc.py", line 895, in media_player_new
    p._instance = self
AttributeError: 'NoneType' object has no attribute '_instance'

Instance.media\u player\u new（）
回溯（最近一次呼叫最后一次）：
文件“”，第1行，在
文件“vlc.py”，第895行，在media_player_new中
p、 _实例=self
AttributeError:“非类型”对象没有属性“\u实例”

我正在使用python 2.6

我的代码有什么问题？

看起来像个bug。我在上浏览了一下代码（参见下面的代码片段）

看起来media_player_new调用libvlc_media_player_new（self），libvlc_media_player_new调用本机libvlc_media_player_new（…）函数。此函数返回NULL，结果为无，后续代码失败

根据文档字符串，如果发生错误，将返回NULL。也许您可以通过libvlc_log函数启用日志记录，看看出了什么问题。指

编辑：看起来您也可以通过vlc.py设置日志记录。（那么您不需要本机呼叫）

打印目录（实例）

？@ZagorulkinDmitry显示vlc.py中的所有函数

def media_player_new(self, uri=None):
    """Create a new MediaPlayer instance.

    @param uri: an optional URI to play in the player.

    p = libvlc_media_player_new(self)
    if uri:
        p.set_media(self.media_new(uri))
    p._instance = self
    return p

def libvlc_media_player_new(p_libvlc_instance):
