写一个视频播放器的代码

这是一个简单的视频播放器的代码，基于Python的Tkinter库和VLC插件：

import tkinter as tk
import vlc

class VideoPlayer:
    def __init__(self, master):
        self.master = master
        self.master.title("视频播放器")
        self.instance = vlc.Instance()
        self.player = self.instance.media_player_new()
        self.player.set_fullscreen(True)
        self.player.set_hwnd(self.master.winfo_id())
        self.frame = tk.Frame(self.master, bg='black')
        self.frame.pack(fill=tk.BOTH, expand=1)
        self.play_button = tk.Button(self.frame, text='播放', command=self.play)
        self.play_button.pack(side=tk.LEFT)
        self.pause_button = tk.Button(self.frame, text='暂停', command=self.pause)
        self.pause_button.pack(side=tk.LEFT)
        self.stop_button = tk.Button(self.frame, text='停止', command=self.stop)
        self.stop_button.pack(side=tk.LEFT)
        self.volume_scale = tk.Scale(self.frame, from_=0, to=100, orient=tk.HORIZONTAL, command=self.set_volume)
        self.volume_scale.set(50)
        self.volume_scale.pack(side=tk.LEFT, fill=tk.BOTH, expand=1)
    
    def play(self):
        media = self.instance.media_new('video.mp4')
        self.player.set_media(media)
        self.player.play()
    
    def pause(self):
        if self.player.is_playing():
            self.player.pause()
        else:
            self.player.play()
    
    def stop(self):
        self.player.stop()
    
    def set_volume(self, val):
        self.player.audio_set_volume(int(val))

if __name__ == '__main__':
    root = tk.Tk()
    player = VideoPlayer(root)
    root.mainloop()

注意：这个代码需要安装VLC插件，可以从官网下载安装。在代码中，`video.mp4`是视频的文件名，需要将其替换为你自己的视频文件名。
