jrtplib編譯

發布時間: 2024-11-01 18:06:01

⑴ 求一份c語言的RTP音頻傳輸源碼

1.項目前期工作(配置好環境)
2.發送端文件編寫(見下面的send.cpp)
3.接收端文件編寫(見下面的receive.cpp)
4.編譯文件
(1)發送端
g++-osendsend.cpp-I/usr/local/include/jrtplib3/-ljrtp
(2)接收端
g++-oreceivereceive.cpp-I/usr/local/include/jrtplib3/-ljrtp
附錄:

⑵ jrtplib-3.11.1怎麼在ubuntu上編譯安裝

1、環境Ubuntu10.04系統,(如果是其他系統可以跳過第2步) 2、安裝庫支持和alien等 sudo apt-get install build-essential sudo apt-get install libstdc++5 sudo apt-get install alien sudo apt-get install g++-multilib 若某步出現安裝不了...
