demo

本地部署之前可以体验开源视频会议公共的服务器demo

1. janus-geteway
   https://janus.conf.meetecho.com/

2. mediasoup
   https://v3demo.mediasoup.org

3. licode
   https://qdt-licode.tk:3004/

4. bigbluebutton

5. openmeetings

本地服务器demo:

1. freeswitch
   https://8.134.56.226/sipml5/call.htm

2. janus-geteway
   https://8.134.56.226/demos/

经过一周的调研
freeswitch janus-geteway mediasoup licode从安装，配置到二次开发都相对比较容易.
bigbluebutton安装及其繁琐.
openmeetings安装配置较容易，是java生态的.

sip接入webrtc服务器
验证了freeswitch和janus-geteway
linphone, zoiper和webrtc视频不能互通，音频倒是能通.
linphone接入不了webrtc视频会议，zoiper可以接入webrtc视频会议.

reference

1. freeswitch
   https://freeswitch.org/confluence/display/FREESWITCH/Debian+9+Stretch
   debian下按官方wiki安装1.10.x版本即可支持视频，默认配置基本可以使用，无需繁琐的自定义配置

   https://gitee.com/dong2/janus-gateway/blob/master/README.md
   注意libwebsockets 不能git checkout v2.4-stable，这个版本加载不了libwebsockets.so，用4.x是正常的.
   注意rabbitmq-c仓库submodule update失败，直接跳过
   注意libnice版本(at least v0.1.16 suggested, master recommended)

3. mediasoup
   据说阿里，头条都在用这个，不过我不想折腾nodejs，优先c/c++生态.
