我就废话不多说了，直接上代码吧！

1.视频分帧：

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 file if cv2.waitKey(10) == 27: break count += 1

2.多帧合成视频：

import cv2 def images_to_video(): fps = 30 # 帧率 num_frames = 500 img_array = [] img_width = 720 img_height = 1280 for i in range(num_frames+1): filename = "./frames/"+str(i)+".png" img = cv2.imread(filename) if img is None: print(filename + " is non-existent!") continue img_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()

以上这篇python-视频分帧&多帧合成视频实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
