参考了下面博主的文章直接用了博主的资源已经测试了是可以运行的工具

我没有自己编译文件，但是博主的文件是有用的！！！

// 这就是调用opencv拉流代码。

        ncnn::MutexLockGuard g(lock);

        if (g_yolo)
        {
            std::vector<Object> objects;
            std::vector<Object> objects_s;
            std::string rtsp1 = "rtsp://XXXXXXXX/h265/ch1/main/av_stream";
            cv::VideoCapture stream1 = cv::VideoCapture(rtsp1,cv::CAP_FFMPEG);
            if (1){
                cv::Mat frame;
                stream1.read(frame);
                cv::imwrite("/sdcard/test/output2.jpg", frame); // 保存图片
            }
