无法将vlc导入python程序

Question

我正在尝试通过 VLC 在 python Tkinter 中重现带声音的视频，但无法运行该文件，因为在运行 import vlc 行时出现错误。

\n\n

我有 32 位的 python 3、32 位的 VLC 播放器并通过安装pip install python-VLC，这是成功的，然后尝试运行代码并收到此错误：

\n\n

File "C:/Users/momoh/Documents/GitHub/CNDH/CNDH.py", line 5, in <module>\n    import vlc\n  File "C:\\Users\\momoh\\AppData\\Local\\Programs\\Python\\Python36-32\\lib\\site-packages\\vlc.py", line 207, in <module>\n    dll, plugin_path  = find_lib()\n  File "C:\\Users\\momoh\\AppData\\Local\\Programs\\Python\\Python36-32\\lib\\site-packages\\vlc.py", line 163, in find_lib\n    dll = ctypes.CDLL(libname)\n  File "C:\\Users\\momoh\\AppData\\Local\\Programs\\Python\\Python36-32\\lib\\ctypes\\__init__.py", line 348, in __init__\n    self._handle = _dlopen(self._name, mode)\nOSError: [WinError 126] The specified module could not be found \n

\n\n

这是我\xc2\xb4m 尝试运行的代码：\n我的导入：

\n\n

import sys\nimport tkinter as tk           \nfrom tkinter import font  as tkfont \nfrom PIL import ImageTk, Image\nimport vlc\n

\n\n

以及包含视频的帧的类

class PageThree(tk.Frame):\n\n    def __init__(self, parent, controller):\n        tk.Frame.__init__(self, parent)\n        self.controller = controller\n        self.grid_columnconfigure(0, weight=0)\n        self.grid_columnconfigure(1, weight=1)\n        self.grid_columnconfigure(2, weight=2)\n        self.grid_columnconfigure(3, weight=1)\n        self.grid_columnconfigure(4, weight=0)\n        self.grid_rowconfigure(0, weight=0)\n        self.grid_rowconfigure(1, weight=1)\n        self.grid_rowconfigure(2, weight=2)\n        self.grid_rowconfigure(3, weight=3)\n        self.grid_rowconfigure(4, weight=2)\n        self.grid_rowconfigure(5, weight=1)\n        self.grid_rowconfigure(6, weight=6)\n\n        self.configure(background="white")\n\n\n        # Open the video source |temporary\n        self.video_source = "assetsCNDH/prueba.mp4"\n\n        # Canvas where to draw video output\n        self.canvas = tk.Canvas(self, width= controller.winfo_screenwidth(),\n                                height=controller.winfo_screenheight(), bg="black",\n                                    highlightthickness=0)\n        self.canvas.pack()\n\n        # Creating VLC player\n        self.instance = vlc.Instance()\n        self.player = self.instance.media_player_new()\n\n    def GetHandle(self):\n        # Getting frame ID\n        return self.winfo_id()\n\n    def play(self, _source):\n        # Function to start player from given source\n        Media = self.instance.media_new(_source)\n        Media.get_mrl()\n        self.player.set_media(Media)\n\n        # self.player.play()\n        self.player.set_hwnd(self.GetHandle())\n        self.player.play()\n

如何让我的视频运行？

Answer 1

Python-vlc is a binding of python to vlc program (or wrapper libraries). It is a way to run vlc program via python (python -> binding -> vlc). It will not run the vlc program itself so you need to do the following steps:

1)  download vlc program and install it in your machine
2)  restart your machine
3)  run notebook again

You may download and install vlc (64-bit) in this link: https://www.videolan.org/vlc/

quote:

Note that this only installs the python module itself, which depends on the availability of the libvlc libraries. You must also install VLC itself to get these libraries.
