1.視頻分幀：?

import cv2vidcap = cv2.VideoCapture('005.avi')success,image = vidcap.read()count = 0success = Truewhile success:success,image = vidcap.read()cv2.imwrite("frame%d.jpg" % count, image) # save frame as JPEG fileif cv2.waitKey(10) == 27:breakcount += 1

2.多幀合成視頻：

import cv2def images_to_video():fps = 30 # 幀率num_frames = 500img_array = []img_width = 720img_height = 1280for i in range(num_frames+1):filename = "./frames/"+str(i)+".png"img = cv2.imread(filename)if img is None:print(filename + " is non-existent!")continueimg_array.append(img)out = cv2.VideoWriter('demo.avi', cv2.VideoWriter_fourcc(*'DIVX'), fps,(img_width,img_height))for i in range(len(img_array)):out.write(img_array[i])out.release()def main():images_to_video()if __name__ == "__main__":main()
