Hide cmd windows 10

[steam3d]

When youtube_dl starts to convert video file via ffmpeg, it show cmd window.
Do anyone know how to hide this cmd window?

After googling. I read this https://trac.ffmpeg.org/wiki/DirectShow#Runningffmpeg.exewithoutopeningaconsolewindow

1. Tried to rename *.py to *.pyw
2. Make exe with pyinstaller with flag --noconsole

It still appears. I have no idea how disable console when ffmpeg start works.

I also found that 2 times this question was closed without any help.

Hi @steam3d ,
Please excuse my naivete. While I understand you perceive this is an issue, would you mind explaining why you think is not a desired behavior? Also, whether you think minimizing the cmd window automatically is an acceptable solution.
Cheers,
