I’m trying to access an RTSP camera in Python and get frame information from it.

One of the camera options is RTSP authentication, and when I include it, VLC asks for login information. (‘[rtsp @ ] method DESCRIBE failed: 401 Unauthorized’)

If I turn it off, I can access it regardless of ID or PW, but if I turn it on, I can’t access it from Python.

I verified that it works by putting the same RTSP address, ID, and PW in VLC, and it doesn’t contain any symbols like ‘@’ which is a common problem.

I used several libraries, including Opencv, ffmpeg, and others, and got the same
‘[rtsp @ ] method DESCRIBE failed: 401 Unauthorized’ and only this error appears

What could be the cause,,, please help…

import cv2

url = "rtsp://username:password@camera_ip:554/stream_path"

cap = cv2.VideoCapture(url)

if not cap.isOpened():
    print("Failed to open RTSP stream.")
    exit()

while True:
    ret, frame = cap.read()
    if not ret:
        print("Failed to read frame.")
        break
    cv2.imshow('RTSP Stream', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

I tried running the above code and debugging it using the ffmpeg library.
