I'm making a program in python that takes an MP4 video, extracts the audio and compresses it, and then takes that compressed audio and takes 0.1 second slices and will process them when I get to coding that, but for now, I'm just making the system for getting the slices. But for some reason, the to part of this defaults to the end of the audio instead of where it's meant to go.

ffmpeg.input("temp.mp3", ss=audioTime).output("slice.mp3", to=audioTime+0.1, acodec="copy").run(quiet=True, overwrite_output=True)

Whole Script:

import moviepy.editor as mp
import ffmpeg
import os

def main():
    wordList = []

    running = True

    percentage = 0

    print("Type ath to video:")

    path = input()

    video = mp.VideoFileClip(path)

    duration = video.duration

    audioTime = 0

    audio = video.audio

    audio.write_audiofile("tempUncompressed.mp3")

    probeBitrate = ffmpeg.probe("tempUncompressed.mp3", v='error', select_streams='a', show_entries='stream=bit_rate')
    probeSampleRate = ffmpeg.probe("tempUncompressed.mp3", v='error', select_streams='a', show_entries='stream=sample_rate')

    bitrate = probeBitrate["streams"][0]['bit_rate']

    sampleRate = probeSampleRate["streams"][0]["sample_rate"]

    bitrate = int(bitrate)

    sampleRate = int(sampleRate)

    bitrate /= 1000

    if bitrate < 100:
        print("The video's audio bitrate is too low! Aborted.")

        running = False

    if sampleRate < 32000:
        print("The video's audio sample rate is too low! Aborted.")

        running = False

    ffmpeg.input("tempUncompressed.mp3").output("temp.mp3", audio_bitrate="100k", ar=32000, y=None).run(quiet=True)

    os.remove("tempUncompressed.mp3")

    duration = round(duration)

    while running:
        ffmpeg.input("temp.mp3", ss=audioTime).output("slice.mp3", to=audioTime+0.1, acodec="copy").run(quiet=True, overwrite_output=True)

        audioTime += 1

        percentage = audioTime/duration*100

        print(f"\rCreating video... {percentage:.2f}%   ", end="", flush=True)

        if audioTime >= duration:
            print("\nDone!")

            running = False

main()

Output:
