Python OpenCV IP camera..error:(-5:Bad argument) CAP_IMAGES: 无法找到视频捕获问题

Question

I am trying to enable this IP cam that I have access to its feed by the browser. but can't access it through a python project to do some object detection stuff. but I can't seem to get the feed to be cv2.videocapture() ed without an error. the link to the camera feed is live and working. the capturing code in the main pythin file:

vs = cv2.VideoCapture('http://<user>:<pass>@<IP>:8080/video.cgi?.mjpg')

I have tried to put rtsp also but no use and I get this error in the cmd when I run the program by command: anything not in <> is exactly how I entered it

[tcp @ 000001f40de13980] Connection to tcp://<IP>:8080 failed: Error number -138 occurred
[ERROR:0] global C:\projects\opencv-python\opencv\modules\videoio\src\cap.cpp (116) cv::VideoCapture::open VIDEOIO(CV_IMAGES): raised OpenCV exception:

OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\videoio\src\cap_images.cpp:253: error: (-5:Bad argument) CAP_IMAGES: can't find starting number (in the name of file): http://<user>:<pass>@<IP>:8080/video.cgi?.mjpg in function 'cv::icvExtractPattern'

1. Streaming laptop camera works Videocapture(0)
2. when searching for the port no. in cmd there where 6 internal links so 6 ports I tried all
3. I installed FFMPEG in laptop and added path but not sure if active in the project because I don't know-how

please explain your answer since I'm new and thanks.

import cv2
cam = cv2.VideoCapture('rtsp://admin:admin@10.10.1.38/H264?ch=1&subtype=0')
