视频智能拆条如何创建

import cv2
import subprocess

def split_video(input_path, output_folder, segment_duration=10):
    cap = cv2.VideoCapture(input_path)
    fps = cap.get(cv2.CAP_PROP_FPS)
    total_frames = int(cap.get(cv2.CAP_PROP_FRAME_COUNT))
    segment_frames = int(fps * segment_duration)

    for start_frame in range(0, total_frames, segment_frames):
        end_frame = min(start_frame + segment_frames, total_frames)
        output_path = f"{output_folder}/segment_{start_frame}.mp4"
        
        command = [
            'ffmpeg',
            '-y',  # Overwrite output file if it exists
            '-ss', str(start_frame / fps),  # Start time
            '-i', input_path,  # Input file
            '-t', str((end_frame - start_frame) / fps),  # Duration
            '-c:v', 'libx264',  # Video codec
            '-c:a', 'aac',  # Audio codec
            output_path  # Output file
        ]
        
        subprocess.run(command, check=True)
    
    cap.release()

# 使用示例
split_video('input_video.mp4', 'output_segments', segment_duration=15)
