比较
RTMPCHybridEngine是为移动端应用量身打造的基于RTMP和RTC混合引擎的连麦互动流媒体直播系统。通过集成本SDK，只需几个简单API调用，便可实现一套完整的连线麦互动直播流媒体应用。包含了流媒体应用中：『采集->编码->传输->解码->播放->连麦视频互动』的所有步骤。
AnyRTC云通讯创新性实现了RTMP+RTC的技术融合，使用RTC技术实现基于标准的RTMP协议的互动连线视频直播，在视频处理，音频降噪，码率控制，硬件加速，美颜滤镜，实时通讯，移动端性能等方面性能优越。
优势：
-
超低延时
-
超低内存
-
无缝连接（原有方案不变的情况，直接嵌入SDK）
-
文字互动、弹幕消息
-
人员上下线
-
多达4人同时在线连麦视频互动
注意事项：
1、直播间页面为香港卫视rtmp数据（当有两台设备可实现适时直播）；
2、演示推流、拉流、连麦至少需要两部iPhone手机；
3、一部手机进入直播页面点击开启直播，开启显示成功后，另一部手机在热门列表下拉刷新，点击列表进入直播间页面。
4、成功后游客端点击左上方连麦按钮，同意后进行连麦。
项目结构：
结构.png
常见问题：
1、无法推流、拉流、连麦->AppDelegate配置SDK失效->官方文档
2、SDK接入需要添加网络权限、访问相机、麦克风权限；
3、可能遇到的问题：
ld: library not found for -XXX
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决：Build Settings->Other Linker Flags->删除XXX
4、 ios Undefined symbols for architecture arm64
解决
开发过程：
准备工作：项目中图片资源通过PP助手获取映客ipa包，接口数据通过抓包工具获得。
SDK集成：项目主要依赖RTMPC SDK 具体请参考官方SDK文档
