Hi strong gayss!
when dealing with audio cutting today, I encountered the following problems. If you have encountered the same problem, please point out one or two
1 and failed to call a third party module pydub to try to cut the audio file of NetEase Yun Music

this is my test code

-sharp -*- coding: utf8 -*-
import re

__author__ = "imagine"

from pydub import AudioSegment as au


def cut(file_path, start_time, end_time):
    audio_format = re.match(".*(\..*)", file_path).group(1)
    mp3 = au.from_file(file_path, format=audio_format)
    mp3[start_time:end_time].export(file_path, format=audio_format)


if __name__ == "__main__":
    cut("/home/createbugofmaster/123.mp3", 17*1000+500, 12*1000+500)

detailed traceback information

in fact, I look at the relevant source code
seems to be executing subprocess.Popen () to call the shell (ffmpeg) script command.
this is a detailed ffmpeg shell script statement ~ ["ffmpeg","-y","- f", "mp3","-I","/ home/createbugofmaster/123.mp3","- vn","- f", "wav"," -"]

 conversion_command += [
            "-vn",  -sharp Drop any video streams if there are any
            "-f", "wav",  -sharp output options (filename last)
            "-"
        ]

        if parameters is not None:
            -sharp extend arguments with arbitrary set
            conversion_command.extend(parameters)

        log_conversion(conversion_command)

        p = subprocess.Popen(conversion_command, stdin=stdin_parameter,
                             stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        p_out, p_err = p.communicate(input=stdin_data)

        if p.returncode != 0 or len(p_out) == 0:
            file.close()
            raise CouldntDecodeError(
                "Decoding failed. ffmpeg returned error code: {0}\n\nOutput from ffmpeg/avlib:\n\n{1}".format(
                    p.returncode, p_err))
