用python写一个脚本：将指定目录下及其所有子文件夹下的视频文件按中间时间切分成两部分

代码：

import os
from moviepy.editor import VideoFileClip

def split_video(video_path, output_dir):
    # 加载视频文件
    clip = VideoFileClip(video_path)
    duration = clip.duration

    # 计算中间时间点
    midpoint = duration / 2

    # 创建输出目录
    if not os.path.exists(output_dir):
        os.makedirs(output_dir)

    # 切分视频
    part1 = clip.subclip(0, midpoint)
    part1_filename = os.path.join(output_dir, os.path.basename(video_path).split('.')[0] + '_part1.mp4')
    part1.write_videofile(part1_filename, codec='libx264', audio_codec='aac')

    part2 = clip.subclip(midpoint, duration)
    part2_filename = os.path.join(output_dir, os.path.basename(video_path).split('.')[0] + '_part2.mp4')
    part2.write_videofile(part2_filename, codec='libx264', audio_codec='aac')

    print(f"视频 {video_path} 已切分为两部分: {part1_filename} 和 {part2_filename}")

def split_videos_in_directory(directory, output_dir):
    for root, dirs, files in os.walk(directory):
        for file in files:
            if file.lower().endswith(('.mp4', '.avi', '.mov', '.mkv')):
                video_path = os.path.join(root, file)
                split_video(video_path, output_dir)

# 指定要处理的目录
source_directory = r'C:\剪映导出\yuan'
# 指定输出目录
output_directory = r'C:\剪映导出\qie'

split_videos_in_directory(source_directory, output_directory)
