我就废话不多说了，直接上代码吧！

# coding: utf-8
import datetime
import cv2
import os

ip = '192.168.3.160'.replace(".", "_") 
rtsp = 'rtsp://admin:admin@192.168.3.160:554/1/1' 
# 初始化摄像头
cap = cv2.VideoCapture(rtsp)

fourcc = cv2.VideoWriter_fourcc(*'XVID')
size = (int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)), int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)))


frame_count = 0
while cap.isOpened():
 isSuccess, frame = cap.read()
 if isSuccess: 
 if frame_count % 120 == 0 or frame_count == 0: 
  frame_count = 0 
  i = datetime.datetime.now().strftime("%Y%m%d%H%M%S") 
  filename = str(i) + '-' + ip + '.avi'
  print(filename)
  video_writer = cv2.VideoWriter(filename, fourcc, 24, size)

 video_writer.write(frame)
 frame_count = frame_count + 1
 print(frame_count)
 if frame_count % 120 == 0: 
  video_writer.release()
  portion = os.path.splitext(filename)
  newname = portion[0] + '.mp4'
  os.rename(filename, newname)
 cv2.imshow('show', frame) 
 if cv2.waitKey(1) & 0xFF == ord('q'):
 break
cap.release()
cv2.destroyAllWindows() 

效果

以上这篇python cv2读取rtsp实时码流按时生成连续视频文件方式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python博客。
