从上面的接口不难看出，就简单的几个接口，几乎可以包含国标GB28181全部功能，包括直播和语音对讲、位置上报等接口，当然，这里面还有很多类似于云台控制、消息订阅等功能，会逐步发布，EasyGBD通过不断的发展，会为GB28181协议的发展贡献一份力量！

SDK空间占用极小

经过优化的EasyGBD空间占用极小，放到IPC里面好选择：
GB28181设备端
后续EasyGBD也将会把各种IPC芯片的so版本或者.a版本发布到Github：https://github.com/easydarwin/EasyGBD，EasyGBD是由EasyDarwin团队贡献的，更多好产品好方案，可以在EasyDarwin获取：www.easydarwin.org
