Problem with RTSP-Cam using @ in the password

[walkonmoon]

Hello,
I have an ONVIF-compatible camera. When I enter the IP address, username, and password, the "inspect" function works perfectly. However, after saving everything and exiting the configuration, I get the error message "check user, password."
The password contains a special character (@), and I cannot change it.
It works without any issues in VLC. Does anyone have an idea here?
