1. Add audio only mode for call.
2. Add SIP/H323 support.
 

经过一个月的紧张开发，h5s视频平台11.5 发布了，包含如下重要功能

1. 由于现在政企客户对网络要求复杂，原先只有WS可以被nginx代理或者NAT映射，为此，11.5 支持了RTC TURN功能，这样RTC也支持nginx代理或者NAT映射功能。

2. 11.5 还带来了RTC上传功能，这样任何终端就可以把现场视频传回给指挥中心。

3. 视频会议和RTC上传功能支持了摄像头的选择。

4. 由于在海思芯片上WebRTC H.264 不支持，11.5 也带来了VP9的支持，随着AV1的普及，后续也会支持AV1。
