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
