i have been trying to access the camera in a frame using OpenCV but it has not worked, I used RTSP to connect it but it did not work. I will attach screenshots of the situation[this is the IP adress and port of the camera] (https://i.sstatic.net/f5B1V1Y6.png) [this is the official websites tutorial, i tried everything but it did not work also] (https://support.hanwhavisionamerica.com/hc/en-us/articles/236372028-What-are-the-RTSP-URLs-of-Hanwha-Devices)

when I try this code with my webcam it works, but whenever i try it with the camera it doesn’t work and gives me the following error

[ WARN:[email protected]] global cap_ffmpeg_impl.hpp:453 _opencv_ffmpeg_interrupt_callback Stream timeout triggered after 30105.778000 ms
