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
