How to convert mp4 into mp3 using ffmpeg (python)

Question

I wanted to convert mp4 files into mp3 files using ffmpeg using python only (no.exe program). I am actually downloading audio files through pytube but all of them get downloaded in mp4 format... and Hence looking looking a way to convert mp4 into mp3 using ffmpeg.

The terminal command for windows is like this ffmpeg -i 1.mp4 1.mp3 I want to know how can I achieve this in python code.

Answer 1

you can try this:-

import os

location = "/download/files/"#or something like that

mp4_file = location + "video.mp4"
mp3_file = location + "audio.mp3"

op = "ffmpeg -i {} -vm {}".format(mp4_file, mp3_file)

os.system(op)
os.system("afplay {}".format(mp3_file))
