关于调用的一点问题

[mahxn0]

您好：
我在调用您的工程的时候，写了如下的demo:
#include "RtspParser.h"

int main(int argc,char *argv[])
{
CRtspParser rtsp_parse;
//char const *progName = "testparse";
//char const *rtspurl = "rtsp://192.168.10.129:8554/cam_update1.264";
void *objstream=nullptr;
rtsp_parse.rtspClientOpenAndPlay("DESCRIBE", "rtsp://192.168.10.29:8554/cam_update1.264", 0, objstream);
}

一运行就会遇到段错误，Segmentation fault (core dumped)
gdb调试打印如下：

请问是我哪里调用不对吗
