用OPenCV分割视频

使用OPencv将分割视频分割成帧

首先安装opencv库

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple opencv-python

使用以下代码，将视频路径和帧图像保存路径换成自己的文件地址：

import cv2def video2frame(videos_path, frames_save_path, time_interval):''':param videos_path: 视频的存放路径:param frames_save_path: 视频切分成帧之后图片的保存路径:param time_interval: 保存间隔:return:'''vidcap = cv2.VideoCapture(videos_path)success, image = vidcap.read()count = 0while success:success, image = vidcap.read()count += 1if count % time_interval == 0:cv2.imencode('.jpg', image)[1].tofile(frames_save_path + "/frame%d.jpg" % count)# if count == 20:#   breakprint(count)if __name__ == '__main__':videos_path = r''frames_save_path = r''time_interval = 2  # 隔一帧保存一次video2frame(videos_path, frames_save_path, time_interval)
