外部编解码器编程指南--AnyChat SDK是一套多媒体即时通讯平台库，大部分需要用到音视频交互的系统都可以采用AnyChat SDK来开发。AnyChat SDK内部封装了音视频的采集、编码、传输、解码以及播放（显示）功能，只需要几个简单的API调用，即可实现多个用户之间的语音、视频、文字交互，由于内核已经实现了P2P网络，所以上层应用不需要关心复杂的网络传输问题，简化了上层应用的开发难度，上层应用的开发人员可以把更多的精力投入到业务流程、用户体验等方面，实现应用系统的快速开发。-External codec Programming Guide- AnyChat SDK is a set of multimedia and instant messaging platform library that most need to use audio and video interactive systems can employ AnyChat SDK to develop. AnyChat SDK internal packaging of audio and video capture, encoding, transmission, decoding and playback (display) function requires only a few simple API calls, you can achieve multiple users for voice, video, text, interaction, because the kernel has been implementation of the P2P network, so the upper application need not concern complex network transmission problems, simplifying the upper application development effort, the upper application developers can put more energy into business processes, user experience, etc., to achieve the application system rapid development.
