如何使用cv2.imwrite保存不同文件夹中多个视频的帧？

import cv2
import os

def save_frames(video_path, output_folder):
    # 打开视频文件
    video = cv2.VideoCapture(video_path)
    
    # 确保视频文件打开成功
    if not video.isOpened():
        print("无法打开视频文件")
        return
    
    # 创建输出文件夹
    os.makedirs(output_folder, exist_ok=True)
    
    # 读取视频帧
    success, frame = video.read()
    count = 0
    
    # 逐帧保存
    while success:
        # 构建输出文件路径
        output_path = os.path.join(output_folder, f"frame_{count}.jpg")
        
        # 保存帧
        cv2.imwrite(output_path, frame)
        
        # 读取下一帧
        success, frame = video.read()
        count += 1
    
    # 关闭视频文件
    video.release()

video_path = "path/to/video.mp4"
output_folder = "path/to/output/folder"

save_frames(video_path, output_folder)
