python cv2读取rtsp实时码流按时生成连续视频文件方式

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
