Я использую модель MatrixIPCamera: камера SATATYA CIDR20FL36CWS, с которой я хочу записывать видео в свой код python.

Я использую:

 import cv2 import os camera = "rtsp://lt;usernamegt;:lt;passwordgt;@lt;Ip addressgt;:lt;Portgt;/Streaming/Channels/2/"  video = cv2.VideoCapture(camera)  

Но каждый раз, когда я получаю:

 [ERROR:0] global /tmp/pip-req-build-l1r0y34w/opencv/modules/videoio/src/cap.cpp (160) open VIDEOIO(CV_IMAGES): raised OpenCV exception:  OpenCV(4.5.3) /tmp/pip-req-build-l1r0y34w/opencv/modules/videoio/src/cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can't find starting number (in the name of file): rtsp://lt;usernamegt;:lt;passwordgt;@lt;Ip addressgt;:lt;Portgt;/Streaming/Channels/2/ in function 'icvExtractPattern'
