python-视频分帧&多帧合成视频实例

我就废话不多说了，直接上代码吧！1.视频分帧：importcv2vidcap=cv2.VideoCapture('005.avi')success,imag

我就废话不多说了，直接上代码吧！

1.视频分帧：

import cv2
vidcap = cv2.VideoCapture('005.avi')
success,image = vidcap.read()
count = 0
success = True
while 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()
