关于JRTPLIB接收的问题

[咋了啦]

我今天调试了JRTPLIB3.71中的sample1，可我发现接收不到数据.
不知道为什么？那位给点建议，我把代码贴出来。
/*
Here's a small IPv4 example: it asks for a portbase and a destination and
starts sending packets to that destination.

std::cin >> destport;

std::cout << std::endl;
std::cout << "Number of packets you wish to be sent:" <<std::endl;

// IMPORTANT: The local timestamp unit MUST be set, otherwise
//RTCP Sender Report info will be calculated wrong

这个例子是可以的啊

应该不是程序的是，看看别的地方吧，环境什么的。

[咋了啦]

呵呵~~~~~~~~
不好意思，是我对他的理解有点问题，在输入的时候弄错 了，现在好了。不过还是谢谢大家的回帖啊

[panther124]

我的输入是这样的：哪里出错了，哪位大侠出来指教下，谢谢了。
Enter lical portbase:
7000

Enter the destination IP address
127.0.0.1 (改成本机的IP 192.168.1.2结果也一样)
Enter the destination port
7002

Number of packets you wish to be sent:
4

Sending pecket 1/4

Sending pecket 1/4

Sending pecket 1/4

Sending pecket 1/4

Enter lical portbase:

7002 ///此处应输入为7000而不是7002
