python调用vlc显示视频实例

将libvlc.dll和libvlccore.dll放在sdk文件夹中，plugins文件夹也放在sdk文件夹中，sdk文件夹放在程序目录下。

我弄这个，实际上是为了推广，我在北京。有意者请加我微信，我的微商微信：xi9902

myvlc.py文件：

import ctypes

import os

class myvlc():

      def __init__(self):

          plugin_arg = r"--plugin-path=" + os.path.join(os.getcwd(), r'sdk\plugins')

          arguments = ["-I", "dummy", "--no-ignore-config", plugin_arg]

          arguments = [bytes(a,"utf-8") for a in arguments]

          p = os.getcwd()

          os.chdir(os.path.join(p, 'sdk'))

          dll = ctypes.CDLL("libvlc.dll")

          os.chdir(p)

          self.dll = dll

          self.libvlc_instance_ = self.dll.libvlc_new(len(arguments),(ctypes.c_char_p * len(arguments))(*arguments))

          self.libvlc_media_player_ = self.dll.libvlc_media_player_new(self.libvlc_instance_)

          self.libvlc_media = None

      def __del__(self):

          self.Stop()

          if(self.libvlc_media):

              self.dll.libvlc_media_release(self.libvlc_media)

          if(self.libvlc_media_player_):

               self.dll.libvlc_media_player_release(self.libvlc_media_player_)

          if(self.libvlc_instance_):

               self.dll.libvlc_release(self.libvlc_instance_)

      def SetRenderWindow(self,hwnd):#嵌入窗体

          if(self.libvlc_instance_):

              self.dll.libvlc_media_player_set_hwnd(self.libvlc_media_player_,hwnd)

      def PlayFile(self,filePath):#播放文件

          if(self.libvlc_media):

              self.dll.libvlc_media_release(self.libvlc_media)

              self.libvlc_media = None

          self.libvlc_media = self.dll.libvlc_media_new_path(self.libvlc_instance_, filePath.encode("utf-8"))

          if(self.libvlc_media):

              self.dll.libvlc_media_player_set_media(self.libvlc_media_player_, self.libvlc_media)

              self.dll.libvlc_media_player_play(self.libvlc_media_player_)

      def PlayUrl(self,filePath):#播放网络流

          if(self.libvlc_media):

              self.dll.libvlc_media_release(self.libvlc_media)

              self.libvlc_media = None

          self.libvlc_media = self.dll.libvlc_media_new_location(self.libvlc_instance_, filePath.encode("utf-8"))

          if(self.libvlc_media):

              self.dll.libvlc_media_player_set_media(self.libvlc_media_player_, self.libvlc_media)

              self.dll.libvlc_media_player_play(self.libvlc_media_player_)

      def Stop(self):#停止播放

          if(self.libvlc_media_player_):

              self.dll.libvlc_media_player_stop(self.libvlc_media_player_)

          if(self.libvlc_media):

              self.dll.libvlc_media_release(self.libvlc_media)

              self.libvlc_media = None

调用方法：

import myvlc

v=myvlc.myvlc()

self.v=v

v.SetRenderWindow(ctypes.c_void_p(int(self.pushButton_8.winId())))

v.PlayFile(r'F:\111.wmv')
