I’m making a monitoring system with Opencv Python via streaming on my Windos 10 OS runs all correctly by irony on my Linux Mate I get the following error message when I try to run

Nonmatching transport in server reply

follows my code:

import cv2

cap = cv2.VideoCapture("rtsp://192.168.25.179:554/onvif1")

while(cap.isOpened()):
    ret, frame = cap.read()
    #print(frame)
    cv2.imshow('frame', frame)
    if cv2.waitKey(20) & 0xFF == ord('q'):
        break
cap.release()
cv2.destroyAllWindows()
python linux opencv

  • And does your Linux have access to rtsp’s network? (access to the IP and port you pointed out)

  • There is another process accessing rtsp at the moment in linux?

happened to me. it has to do with system variables.

you can start like this:

import os
os.environ["OPENCV_FFMPEG_CAPTURE_OPTIONS"] = "rtsp_transport;udp"

cap = cv2.VideoCapture("rtsp://192.168.25.179:554/onvif1", cv2.CAP_FFMPEG)

I advise you to install the full package of v4l2 on linux usually tbm resolves.
