Running AudioSegment.from_mp3 or audio.export ，the cmd command window always flash

[1893945]

Steps to reproduce

Expected behavior

I used pyinstaller cteate a quiet exe， when Running AudioSegment.from_mp3 or audio.export not need to pop up the cmd command window.

Actual behavior

But when Running AudioSegment.from_mp3 or AudioSegment.export ，the cmd command window always flash

Your System configuration

• Python version: 3.8
• Pydub version: pydub==0.24.1
• ffmpeg or avlib?: ffmpeg
• ffmpeg/avlib version: ffmpeg 5.1

Is there an audio file you can include to help us reproduce?

You can include the audio file in this issue - just put it in a zip file and drag/drop the zip file into the github issue.

add code : startupinfo = subprocess.STARTUPINFO() startupinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE|subprocess.STARTF_USESHOWWINDOW startupinfo.wShowWindow = subprocess.SW_HIDE

   p = subprocess.Popen(conversion_command, stdin=devnull, stdout=subprocess.PIPE, stderr=subprocess.PIPE, startupinfo=startupinfo)

AudioSegment.export not pop up cmd window, But AudioSegment.from_mp3 pop up cmd window yet.

why?

[1893945]

Problem solved.

startupinfo = subprocess.STARTUPINFO() startupinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE|subprocess.STARTF_USESHOWWINDOW startupinfo.wShowWindow = subprocess.SW_HIDE

the codes is available. AudioSegment.from_mp3 called pydub‘s utils.py, some subprocess.Pooen in utils.py, set them all “startupinfo=startupinfo”.

Where do I add this code to? Is it in "audio_segment.py"? Thank you!

Thanks a lot for your solution! I found another way to modify subprocess.Popen in pydub without changing its internal files.

1. Create patch_subprocess.py with the following content:

   
   import subprocess

class NoWindowPopen(subprocess.Popen): def init(self, *args, **kwargs): startupinfo = subprocess.STARTUPINFO() startupinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE | subprocess.STARTF_USESHOWWINDOW startupinfo.wShowWindow = subprocess.SW_HIDE

    kwargs["startupinfo"] = startupinfo
    super().__init__(*args, **kwargs)

subprocess.Popen = NoWindowPopen

2. Import `patch_subprocess` before import `pydub`

import patch_subprocess from pydub import AudioSegment
