# WebRTC 插件
|
|
|
|
|
|
|
|
|
|
提供通过网页发布视频到monibuca，以及从monibuca拉流通过webrtc进行播放的功能，遵循WHIP规范
|
|
|
|
|
|
|
|
|
|
## 插件地址
|
|
|
|

|
|
https://github.com/Monibuca/plugin-webrtc
|
|
|
|
|
|
|
|
|
|
## 插件引入
|
|
|
|
|
```go
|
|
|
|
|
import ( _ "m7s.live/plugin/webrtc/v4" )
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## 默认配置
|
|
|
|
|
|
|
|
|
|
```yaml
|
|
|
|
|
webrtc:
|
|
|
|
|
iceservers: []
|
|
|
|
|
publicip: [] # 可以是数组也可以是字符串（内部自动转成数组）
|
|
|
|
|
portmin: 0
|
|
|
|
|
portmax: 0
|
|
|
|
|
inviteportfixed: true // 设备将流发送的端口，是否固定 on 发送流到多路复用端口 如9000 off 自动从 mix_port - max_port 之间的值中 选一个可以用的端口
|
|
|
|
|
iceudpmux: 9000 // 接收设备端rtp流的多路复用端口
|
|
|
|
|
pli: 2000000000 # 2s
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### 本地测试无需修改配置，如果远程访问，则需要配置publicip
|
|

|
|
|
## 基本原理
|
|
|
|
|
|
|
|
|
|
通过浏览器和monibuca交换sdp信息，然后读取rtp包或者发送rtp的方式进行
|
|
|
|
|
|
|
