Python脚本，音频格式转换 和 视频格式转换

一、音频格式转换完整代码

from pydub import AudioSegment
import os


def convert_audio(input_dir, output_dir, target_format):
    if not os.path.exists(output_dir):
        os.makedirs(output_dir)

    for filename in os.listdir(input_dir):
        if filename.endswith(('.mp3', '.wav', '.ogg')):
            input_path = os.path.join(input_dir, filename)
            output_filename = os.path.splitext(filename)[0] + f".{target_format}"
            output_path = os.path.join(output_dir, output_filename)

            audio = AudioSegment.from_file(input_path)
            audio.export(output_path, format=target_format)
            print(f"Converted {filename} to {output_filename}")


convert_audio("./input_audio", "./output_audio", "mp3")

二、视频格式转换完整代码

from moviepy import *

def convert_video_format(input_path, output_path):
    """将视频转换为不同格式"""
    try:
        video = VideoFileClip(input_path)
        video.write_videofile(output_path)
        video.close()
        print(f"转换完成: {output_path}")
    except Exception as e:
        print(f"转换失败: {str(e)}")

# 使用示例
convert_video_format("input.mp4", "output.avi")
