以上源码有一定的修改和裁剪，感谢MediaSoup开源项目及作者，
|
||||
用户在使用本项目的同时，应该同时遵循MediaSoup的开源协议。
|
||||
|
||||
同时,在此也感谢开源项目[easy_webrtc_server](https://github.com/Mihawk086/easy_webrtc_server) 及作者，
|
||||
在集成MediaSoup相关代码前期，主要参考这个项目。
|
||||
|
||||
另外，感谢[big panda](<2381267071@qq.com>) 开发并贡献的webrtc js测试客户端(www/webrtc目录下文件)，
|

# 现状与规划
|
||||
ZLMediaKit的WebRTC相关功能目前仅供测试与开发，现在还不成熟，后续主要工作有：
|
||||
|
||||
- 1、完善webrtc rtcp相关功能，包括丢包重传、带宽检测等功能。
|
||||
- 2、实现rtp重传等相关功能。
|
||||
- 3、实现simulecast相关功能。
|
||||
- 4、fec、rtp扩展等其他功能。
|
||||
- 5、如果精力允许，逐步替换MediaSoup相关代码，改用自有版权代码。
