关于pydub AudioSegment处理mp3文件的一系列的坑

首先报错：
E:\Anaconda_all\lib\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn’t find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn(“Couldn’t find ffmpeg or avconv - defaulting to ffmpeg, but may not work”, RuntimeWarning)
E:\Anaconda_all\lib\site-packages\pydub\utils.py:198: RuntimeWarning: Couldn’t find ffprobe or avprobe - defaulting to ffprobe, but may not work
warn(“Couldn’t find ffprobe or avprobe - defaulting to ffprobe, but may not work”, RuntimeWarning)
以及 filenotfound

首先要想使用pydub库，需要先安装ffmpeg
其次，安装ffmpeg用pip install并没有什么用，需要去官网，下载静态文件，然后将ffmpeg文件的bin目录添加到路径
依然还是没有用，可能是anaconda的原因？将Anaconda_all\lib\site-packages\pydub\utils.py，里面的which函数的路径处理部分后面加上：

envdir_list.append(r'D:\ffmpeg-20200628-4cfcfb3-win64-static\bin')#添加这一行，注意里面的路径是ffmpeg.exe所在的路径

虽然不报警告了，但依然notfound
于是尝试根据网上的回答，在代码中手动加上ffmpeg的路径，依然不行
最后直接把bin文件里面的ffmpeg，ffprobe等三个exe复制到当前目录，成功了。。。

兴高采烈开始处理mp3，结果又报错：

Traceback (most recent call last):
  File "f:\officialschool\project\trymp3.py", line 13, in <module>
    genSong()
  File "f:\officialschool\project\trymp3.py", line 7, in genSong
    song = AudioSegment.from_mp3(path + 'z.mp3')
  File "E:\Anaconda_all\lib\site-packages\pydub\audio_segment.py", line 738, in from_mp3
    return cls.from_file(file, 'mp3', parameters=parameters)
  File "E:\Anaconda_all\lib\site-packages\pydub\audio_segment.py", line 725, in from_file
    p.returncode, p_err.decode(errors='ignore') ))
pydub.exceptions.CouldntDecodeError: Decoding failed. ffmpeg returned error code: 1

Output from ffmpeg/avlib:

一开始代码中是相对路径，有人说需要是绝对路径，改了，无用
有人说from_mp3函数不行，需要是from_file，无用
最后发现是自己mp3文件的时期，换了一个文件就可以了。。
