Python-133 MP3 用pygame等包完成简约播放器的

Capture.JPG

1. 简约版的制作：这一个版本其实就是一个简单的单曲loading然后播放，因此只能一个个播放！

---

• 具体代码：

from tkinter import *
from tkinter import filedialog
from pygame import mixer

class MusicPlayer:
    def __init__(self, window ):
        window.geometry('320x130'); window.title('MP3 Player By Rashidin Abdugheni'); window.resizable(0,0)
        Load = Button(window, text = 'Load',  activebackground='red', width = 10, font = ('Black', 14),bg='#A9F5F2', command = self.load)
        Play = Button(window, text = 'Play',   activebackground='red',width = 10,font = ('Black', 14), bg='#A9F5F2',command = self.play)
        Pause = Button(window,text = 'Pause',   activebackground='red',width = 10, font = ('Black',14), bg='#A9F5F2',command = self.pause)
        Stop = Button(window ,text = 'Stop',   activebackground='red',width = 10, font = ('Black', 14), bg='#A9F5F2',command = self.stop)

        Load.place(x=40,y=10);Play.place(x=160,y=10);Pause.place(x=40,y=60);Stop.place(x=160,y=60)
        self.music_file = False
        self.playing_state = False
    def load(self):
        self.music_file = filedialog.askopenfilename()
    def play(self):
        if self.music_file:
            mixer.init()
            mixer.music.load(self.music_file)
            mixer.music.play()
    def pause(self):
        if not self.playing_state:
            mixer.music.pause()
            self.playing_state=True
        else:
            mixer.music.unpause()
            self.playing_state = False
    def stop(self):
        mixer.music.stop()
root = Tk()
root.configure(bg='black')
app= MusicPlayer(root)
root.mainloop()

• 运行结果：

• 进行打包：用pyinstaller，因此首先安装这个,即在terminal

pip install pyinstaller

完成安装后，可以进行打包了：

 pyinstaller -w .\MP3_Player_RA20211112.py

• 注意：

• 1)为了不一个个输入文件位置，直接在运行框下面terminal进行打包！
• 2)为了只生成不显示运行框的文件，用了“w”参数，如果想要显示运行框可以用F参数，即：

pyinstaller -F .\MP3_Player_RA20211112.py

这样就在文件夹里获得了对应的打包后的成果：

运行即可！

就这样单曲可以播放了！

2. 高级版的制作：这一个版本其实就是一个简单的多曲loading然后播放！

• 代码如下：

import os
import tkinter
import tkinter.filedialog
import time
import threading
import pygame  # 实现音频播放
root = tkinter.Tk()
root.title('MP3 Player 1.0 By Rashidin Abdugheni 🦅')
root.configure(bg='#9FF781')
root.geometry('460x600')
root.resizable(False, False)
# And Image should be in the same folder where there is script saved
#p1 = PhotoImage(file = 'C:/Users/Mr.R/Pictures/1.jpg')


folder = ''  # 接收文件路径 默认为空
res = []  #
num = 0
now_music = ''


# 第二步：实现功能

def buttonChooseClick():
    # 添加文件函数

    global folder
    global res
    # 如果folder不为空，则····
    if not folder:
        folder = tkinter.filedialog.askdirectory()  # 选择目录，返回目录名
        musics = [folder + '\\' + music
                  for music in os.listdir(folder) \
 \
                  if music.endswith(('.mp3', '.m4a', '.wav', '.ogg'))]

        ret = []
        for i in musics:
            ret.append(i.split('\\')[1:])
            res.append(i.replace("\\", '/'))

        var2 = tkinter.StringVar()
        var2.set(ret)
        lb = tkinter.Listbox(root, listvariable=var2)
        lb.place(x=70, y=230, width=300, height=300)

    if not folder:
        return
    global playing
    playing = True

    # 根据情况禁用或启用相应按钮

    bottonPlay['state'] = 'normal'
    bottonStop['state'] = 'normal'

    # buttonPause['state'] = 'normal'

    pause_resume.set('Play')


# 播放音乐函数
def play():
    # 初始化混响设备

    if len(res):
        pygame.mixer.init()
        global num
        while playing:
            if not pygame.mixer.music.get_busy():
                # 随机播放
                nextMusci = res[num]
                print(nextMusci)
                print(num)
                pygame.mixer.music.load(nextMusci.encode())
                # 播放一次
                pygame.mixer.music.play(1)
                # print(len(res)-1)
                if len(res) - 1 == num:
                    num = 0
                else:
                    num += 1
                nextMusci = nextMusci.split("\\")[1:]
                musicName.set('Playing...' + ''.join(nextMusci))
            else:
                time.sleep(0.1)


# 点击播放函数

        pause_resume.set('Pause')
        global folder

        if not folder:
            # 选择目录，返回目录名
            folder = tkinter.filedialog.askdirectory()

            return

        global playing

    time.sleep(0.3)

    try:

        pygame.mixer.quit()

    except:
        pass
    root.destroy()


# 声音控制函数
def control_voice(value=0.5):
    pygame.mixer.music.set_volume(float(value))


# 添加按钮
bottonChoose = tkinter.Button(root, text='Add Musics',fg="Red", command=buttonChooseClick,bg="sky blue")
# 按钮布局
bottonChoose.place(x=70, y=50, width=140, height=20)

# 播放按钮  跟踪变量值的变化
pause_resume = tkinter.StringVar(root, value='Play')

bottonPlay['state'] = 'disabled'  # 未添加文件（刚启动）时禁用

# 停止播放
bottonStop = tkinter.Button(root, text='Stop',bg="sky blue")
# 按钮布局
bottonStop.place(x=70, y=80, width=140, height=20)

# 下一首
bottonNext = tkinter.Button(root, text='Next', command=bottonNextClik,bg="sky blue",fg="Red")

# 显示内容--播放状态

# 启用消息循环:显示出上一步创建的画板对象
root.mainloop()

运行结果：

• 进行打包：

 pyinstaller -F .\RA_MP3_Player.py

• 或者：

 pyinstaller -w .\RA_MP3_Player.py

• 进行打包！

• 得到：

• 运行添加音乐并播放音乐！这时可以调整音乐声音啥的！

另外：遇到了几个报错问题，可以用以下方式解决：

1) 问题1 ： Failed loading libmpg123-0.dll: The specified module could not be found.

解决方法：

• 首先搜索：libmpg123-0.dll，将找到的dll文件进行复制！
• 打开电脑位置：

C:\Windows

会看到：

image.png

• 将上面复制的dll文件分别放入到上面的两个文件夹里，然后重新启动pycharm进行运行，然后试着播放，全程没问题了再进行打包！这样就完美解决了！
