Question

def download_audio():
#try:
    b2.config(text="Please wait...")
    b2.config(state=DISABLED)
    stream = yt.streams.filter(res="480p")
    path = filedialog.askdirectory()
    if path == None:
        return
    stream[0].download(path)
    for i in os.listdir(path):
        os.rename(os.path.join(path,i),os.path.join(path,i.replace(' ','_')))
    title = yt.title.replace(' ','_')
    print(title)
    print(path)
    video = VideoFileClip(os.path.join(path+"//"+title+".mp4"))
    print(video)
    video.audio.write_audiofile(os.path.join(path+"//"+title+".mp3"))

This is the Error message 属性错误：NoneType对象没有属性write_audiofile

Answer 1

尝试：

def download_audio():
#try:
    b2.config(text="Please wait...")
    b2.config(state=DISABLED)
    stream = yt.streams.filter(res="480p")
    path = filedialog.askdirectory()
    if path == None:
        return
    stream[0].download(path)
    for i in os.listdir(path):
        os.rename(os.path.join(path,i),os.path.join(path,i.replace(' ','_')))
    title = yt.title.replace(' ','_')
    print(title)
    print(path)
    video = VideoFileClip(os.path.join(path,title+".mp4"))
    print(video)
    video.audio.write_audiofile(os.path.join(path,title+".mp3"))

需要在os.path中使用逗号而不是“ //”来构建路径。

Answer 2

尝试video.write_audiofile(os.path.join(path+"//"+title+".mp3"))

使用ffmpeg转换视频或使用opencv进行所有视频管理可能会更好。

Answer 3

弄清楚了。实际上，streams.filter（“ 480p”）给了我一个没有音频的纯视频流，这就是为什么nonetype错误的原因，因为它没有音频对象。通过执行stream.filter（progressive = True）解决了这个问题。

def download_audio():
#try:
b2.config(text="Please wait...")
b2.config(state=DISABLED)
stream = yt.streams.filter(progressive=True)
path = filedialog.askdirectory()
if path == None:
    return
stream[0].download(path)
for i in os.listdir(path):
    os.rename(os.path.join(path,i),os.path.join(path,i.replace(' ','_')))
title = yt.title.replace(' ','_')
print(title)
print(path)
video = VideoFileClip(os.path.join(path+"//"+title+".mp4"))
print(video)
video.audio.write_audiofile(os.path.join(path+"//"+title+".mp3"))

我正在尝试通过使用MoviePy模块将视频mp4文件转换为音频mp3格式，但向我显示Nonetype错误
