 ## Why ZLMediaKit?
 - Developed based on C++ 11, the code is stable and reliable, avoiding the use of raw pointers, cross-platform porting is simple and convenient, and the code is clear and concise.
- Support rich streaming media protocols(`RTSP/RTMP/HLS/HTTP-FLV`),and support Inter-protocol conversion.
+- Support rich streaming media protocols(`RTSP/RTMP/HLS/HTTP-FLV/Websocket-flv`),and support Inter-protocol conversion.
 - Multiplexing asynchronous network IO based on epoll and multi thread，extreme performance.
 - Well performance and stable test,can be used commercially.
 - Support linux, macos, ios, android, Windows Platforms.
 - Very low latency(lower then one second), video opened immediately.
- **Now Support websocket-flv!**

 ## 项目特点
 - 基于C++11开发，避免使用裸指针，代码稳定可靠；同时跨平台移植简单方便，代码清晰简洁。
- 打包多种流媒体协议(RTSP/RTMP/HLS），支持协议间的互相转换，提供一站式的服务。
+- 打包多种流媒体协议(RTSP/RTMP/HLS/HTTP-FLV/Websocket-FLV），支持协议间的互相转换，提供一站式的服务。
 - 使用epoll+线程池+异步网络IO模式开发，并发性能优越。
 - 已实现主流的的H264/H265+AAC流媒体方案，代码精简,脉络清晰，适合学习。
 - 编码格式与框架代码解耦，方便自由简洁的添加支持其他编码格式
 - 代码经过大量的稳定性、性能测试，可满足商用服务器项目。
 - 支持linux、macos、ios、android、windows平台
 - 支持画面秒开(GOP缓存)、极低延时([500毫秒内，最低可达100毫秒](https://github.com/zlmediakit/ZLMediaKit/wiki/%E5%BB%B6%E6%97%B6%E6%B5%8B%E8%AF%95))
- **支持websocket-flv直播**
 - [ZLMediaKit高并发实现原理](https://github.com/xiongziliang/ZLMediaKit/wiki/ZLMediaKit%E9%AB%98%E5%B9%B6%E5%8F%91%E5%AE%9E%E7%8E%B0%E5%8E%9F%E7%90%86)
