# Monibuca 的RTSP 插件

主要功能是对RTSP地址进行拉流转换

主要功能是提供RTSP的端口监听接受RTSP推流，以及对RTSP地址进行拉流转发

## 配置
|
||||
```toml
|
||||
[RTSP]
|
||||
ListenAddr = ":554"
|
||||
BufferLength = 2048
|
||||
AutoPull = false
|
||||
RemoteAddr = "rtsp://localhost/${streamPath}"
|
||||
```
|
||||
- ListenAddr 是监听端口，可以将rtsp流推到Monibuca中
|
||||
- BufferLength是指解析拉取的rtp包的缓冲大小
|
||||
- AutoPull是指当有用户订阅一个新房间的时候自动向远程拉流转发
|
||||
- AutoPull是指当有用户订阅一个新流的时候自动向远程拉流转发
|
||||
- RemoteAddr 指远程拉流地址，其中${streamPath}是占位符，实际使用流路径替换。
|
||||
|
||||
|
||||
## 使用方法(拉流转发)
|
||||
```go
|
||||
new(RTSP).Publish("live/user1","rtsp://xxx.xxx.xxx.xxx/live/user1")
|
||||
new(RTSP).PullStream("live/user1","rtsp://xxx.xxx.xxx.xxx/live/user1")
