Mp3 播放器 - 每次播放文件时都会出现“找不到文件"消息框.showerror [英] Mp3 player - the “file not found” messagebox.showerror shows up every time I play a file

问题描述

下面的代码是一个媒体播放器 (mp3).它运行良好，直到我添加了 show_details() 函数，该函数应该显示歌曲的长度和时间，播放文件时出现错误消息找不到文件"(文件确实播放！但错误消息每次都会弹出).一旦我去掉由 'a'、'total_length' 和 'print' 语句组成的 3 行，错误就会停止出现，歌曲当然可以正常播放.我的代码有什么问题?

The code below is a media player (mp3). It worked perfectly until I added the show_details() function which is supposed to show the length and timing of the song, the error message "file not found" appears when playing a file (The file does play! but the error message pops everytime). Once I take off the 3 lines consisting of 'a', 'total_length' and 'print' statements, the error stops to show up and the song of course plays normally. What is the problem with my code?

filelabel = Label(root, text="Let's make some noise!")
filelabel.pack(pady=10)

lengthlabel = Label(root, text="Total Length - 00:00")
lengthlabel.pack(pady=10)

def show_details():
    filelabel['text'] = 'Playing - ' + os.path.basename(filename)
    a = mixer.Sound(filename)
    total_length = a.get_length()
    print (total_length)

def play_music():
    global paused

    if paused:
        mixer.music.unpause()
        statusbar['text'] = 'Music Resumed: Playing ' + os.path.basename(filename)
        paused = False
    else:
        try:
            mixer.music.load(filename)
            mixer.music.play()
            statusbar['text'] = 'Playing - ' + os.path.basename(filename)
            show_details()
        except:
            tkinter.messagebox.showerror('FIle not found', 'Melody could not find the song, please check again')

推荐答案

我看到您同时创建了一个音乐和声音对象.这可能是您答案的线索:如何在在 pygame 中的同一时间?

I see you create a music and sound object at the same time. This might be a clue to your answer: How can I play multiple sounds at the same time in pygame?

似乎添加频道可能会解决您的问题.不过先把这三行拿出来看看是不是原因:

It seems that adding channels might fix your problem. But take out these three lines first to see if they are the cause:

a = mixer.Sound(filename)
total_length = a.get_length()
print (total_length)
