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：
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()
