How should I set a timeout for RTSP?

I am using NUGET to retrieve OpenCvSharp4. Attempt to obtain every frame of RTSP images and send them out using SOCKET
But when I use it, I find that if the IP cannot connect, VideoCapture. Open will take a long time to execute. I need to set it shorter. How should I proceed?

Below is the original Chinese text

我正在使用NUGET 获取的OpenCvSharp4。尝试获取rtsp的每一帧图片并用SOCKET发送出去.
但是在我使用的时候发现，如果IP无法连接，VideoCapture.Open 就会执行很长的时间，我需要将其设置短一些，我应该如何操作？

Environment

.net Framework4.6.2
OpenCvSharp4 4.10.0.2024.0616
