C++ 语言 开发 WebRTC 分布式高性能媒体处理

WebRTC 分布式高性能媒体处理：C++ 代码实现解析

随着互联网技术的飞速发展，实时通信（Real-time Communication，简称RTC）技术逐渐成为网络应用的重要组成部分。WebRTC（Web Real-Time Communication）作为一种新兴的RTC技术，允许用户在浏览器中直接进行音视频通信，无需安装任何插件。本文将围绕WebRTC分布式高性能媒体处理这一主题，使用C++语言进行代码实现，并对其关键技术进行解析。

WebRTC 简介

WebRTC是一种开放源代码的实时通信技术，它允许在浏览器之间进行点对点通信，无需服务器中转。WebRTC支持多种媒体类型，包括音频、视频和数据通道。它主要由以下几个模块组成：

1. 信令模块：负责在客户端和服务器之间传递信令信息，如SDP（Session Description Protocol）和ICE（Interactive Connectivity Establishment）。
2. 媒体模块：负责处理音视频数据，包括编解码、网络传输和回声消除等。
3. 网络模块：负责处理网络连接，包括STUN/TURN服务器交互、ICE候选生成和NAT穿透等。

C++ 代码实现

以下是一个简单的WebRTC C++代码示例，展示了如何创建一个WebRTC客户端，并实现音视频通信。
