环境搭建等参考：JRTP实时音视频传输(1)-必做的环境搭建与demo测试

1.创建自己的demo

先将example1拷贝为myclienttcp.cpp和myservertcp.cpp
cp example1.cpp myclienttcp.cpp
cp example1.cpp myservertcp.cpp

改写jrtplib/JRTPLIB/examples/CMakeLists.txt，添加myclienttcp和myservertcp编译
JRTP实时音视频传输(2)-使用TCP通信的案例,jrtp,音视频学习,实时音视频,tcp/ip,网络,linux
重新生成Makefile并编译

sudo cmake CMakeLists.txt
sudo make

可以看到成功编译了myclienttcp和myservertcp源文件

编译通过，这里就去实现demo就行

4.demo运行测试

分别运行client和server ，可以看到数据正常传输到server端

用netstat查看连接端口信息，也能看到该端口目前的状态，属于TCP连接，实验成功
