if you want to process only a image except a packet, you can easily process a image by using the below code.
#include <iostream>
#include <opencv2/opencv.hpp>
int main()
{
cv::VideoCapture vc("your rtsp address");
if(vc.isOpened())
{
cv::Mat src;
while(vc.read(src))
{
cv::imshow("src",src);
cv::waitKey(10);
}
}
return 0;
}
