 # RTSP插件
-rtsp插件提供rtsp协议的推拉流能力，以及向远程服务器推拉rtsp协议的能力。
+
 ## 插件地址

-https://github.com/Monibuca/plugin-rtsp
+github.com/Monibuca/plugin-rtsp

 ## 插件引入
 ```go
 import (
-    _ "m7s.live/plugin/rtsp/v4"
+    _ "github.com/Monibuca/plugin-rtsp"
 )
 ```

-## 推拉地址形式
-```
-rtsp://localhost/live/test
-```
- `localhost`是m7s的服务器域名或者IP地址，默认端口`554`可以不写，否则需要写
- `live`代表`appName`
- `test`代表`streamName`
- m7s中`live/test`将作为`streamPath`为流的唯一标识
+## 默认插件配置

+```toml
+[RTSP]
+# 端口接收推流
+ListenAddr = ":554"
+Reconnect = true
+[RTSP.AutoPullList]
+"live/rtsp1" = "rtsp://admin:admin@192.168.1.212:554/cam/realmonitor?channel=1&subtype=1"
+"live/rtsp2" = "rtsp://admin:admin@192.168.1.212:554/cam/realmonitor?channel=2&subtype=1"
+```
+
+- `ListenAddr`是监听的地址
+- `Reconnect` 是否自动重连
+- `RTSP.AutoPullList` 可以配置多项，用于自动拉流，key是streamPath，value是远程rtsp地址
+
+### 特殊功能
+
+当自动拉流列表中当的streamPath为sub/xxx 这种形式的话，在gb28181的分屏显示时会优先采用rtsp流，已实现分屏观看子码流效果
+## 插件功能
+
+### 接收RTSP协议的推流

 例如通过ffmpeg向m7s进行推流

 ```bash
-ffmpeg -i [视频源] -c:v h264 -f rtsp rtsp://localhost/live/test
+ffmpeg -i **** rtsp://localhost/live/test
 ```

 会在m7s内部形成一个名为live/test的流

+### 从远程拉取rtsp到m7s中

-如果m7s中已经存在live/test流的话就可以用rtsp协议进行播放
-```bash
-ffplay rtsp://localhost/live/test
+可调用接口
+`/api/rtsp/pull?target=[RTSP地址]&streamPath=[流标识]`
+
+## 使用编程方式拉流
+```go
+new(RTSP).PullStream("live/user1","rtsp://xxx.xxx.xxx.xxx/live/user1") 
 ```

+### 罗列所有的rtsp协议的流

-## 配置
+可调用接口
+`/api/rtsp/list`

-```yaml
-rtsp:
-    publish:
-        pubaudio: true
-        pubvideo: true
-        kickexist: false
-        publishtimeout: 10
-        waitclosetimeout: 0
-    subscribe:
-        subaudio: true
-        subvideo: true
-        iframeonly: false
-        waittimeout: 10
-    pull:
-        repull: 0
-        pullonstart: false
-        pullonsubscribe: false
-        pulllist: {}
-    push:
-        repush: 0
-        pushlist: {}
-    listenaddr: :554
-    udpaddr: :8000
-    rtcpaddr: :8001
-    readbuffersize: 2048
-    pullprotocol: 'auto'
-```
-:::tip 配置覆盖
-publish
-subscribe
-两项中未配置部分将使用全局配置
-:::
-## API
+### 从m7s中拉取rtsp协议流

-### `rtsp/api/list`
-获取所有rtsp流
-
-### `rtsp/api/pull?target=[RTSP地址]&streamPath=[流标识]`
-从远程拉取rtsp到m7s中
-
-### `rtsp/api/push?target=[RTSP地址]&streamPath=[流标识]`
-将本地的流推送到远端
+直接通过协议rtsp://xxx.xxx.xxx.xxx/live/user1 即可播放
+> h265和aac 编码拉流尚未实现，敬请期待
