Multithreading / Multiprocessing python for loop

Question

I would like to use multiprocessing / or multithreading : do not know which is the best for my use case : converting mp4 file to mp3 file (guess multiprocessing ?).

Main problem is that the function which I want to iterate (conv_all_files) has a loop and I do not know how to multiprocess it...

Here is the code :

def conv_file(input,output):
    subprocess.run(["ffmpeg","-i",input,output + ".mp3","-loglevel","quiet"])

def conv_all_files():
    for i in os.listdir(MP4_Path):
        conv_file(MP4_Path + "\" + i,MP3_Path + "\" + i)

Any ideas ?
