# anyrtc-push

小程序自定义组件

> 使用此组件需要依赖小程序基础库 2.2.1 以上版本，同时依赖开发者工具的 npm 构建。具体详情可查阅[官方 npm 文档](https://developers.weixin.qq.com/miniprogram/dev/devtools/npm.html)。

# 使用说明

> 1.结合[anyrtc小程序会议SDK](https://www.npmjs.com/package/miniprogram-anyrtc-meet)使用  
> 2.结合[anyrtc小程序推流组件](https://www.npmjs.com/package/miniprogram-anyrtc-push)和[anyrtc小程序拉流组件](https://www.npmjs.com/package/miniprogram-anyrtc-play)使用

# 使用方法

1. 安装 anyrtc-push  

```
npm install --save miniprogram-anyrtc-push
```

2. 在需要使用 slide-view 的页面 page.json 中添加 anyrtc-push 自定义组件配置

```
{
  "usingComponents": {
    "anyrtc-push": "miniprogram-anyrtc-push"
  }
}
```

WXML 文件中引用 anyrtc-push

```
<!-- anyrtc发布 -->
<anyrtc-push 
  id="anyrtcpush"
  width="{{pushWidth}}"
  height="200"
  coverImg=""
  enableAudio="{{enableAudio}}"
  enableVideo="{{enableVideo}}"
  pushURL="{{pushURL}}" 
  bindRoomEvent="handleRoomEvent">
 </anyrtc-push>

```
### anyrtc-push的属性介绍如下：

|属性名|类型|默认值|是否必须|说明|
|--|--|--|--|--|--|
|pushURL|String|-|是|anyrtc-push组件推流URL|
|id|String|-|是|用户获取组件的```LivePusherContext```来切换摄像头等[操作](https://developers.weixin.qq.com/miniprogram/dev/api/media/live/LivePusherContext.html)。|
|width|Number|显示屏幕的宽度|是|anyrtc-push组件的宽度|
|height|Number|0|是|anyrtc-push组件的高度|
|coverImg|String|-|否|anyrtc-push组件进入后台时推流的等待画面|
|enableAudio|Boolean|true|否|anyrtc-push组件是否静音|
|enableVideo|Boolean|true|否|anyrtc-push组件是否开启摄像头|
|bindRoomEvent|Functiong|-|是|anyrtc-push组件接收在线人员信息、推流等信息|


### anyrtc-push的方法介绍如下

**注意：    
当需要停止推流、回复推流、切换摄像头等操作时，需要获取到推流组件对象后，才可对其进行操作。    
打开/关闭摄像头、打开/关闭麦克风则改变推流组件对外属性```enableVideo```和```enableAudio```即可。  
具体看Demo**


1. 停止推流
```
//that为当前页面对象
that.selectComponent('#anyrtcpush').pause()

```
2. 恢复推流
```
//that为当前页面对象
that.selectComponent('#anyrtcpush').resume()
```
3. 切换前后置摄像头
```
//that为当前页面对象
that.selectComponent('#anyrtcpush').switchCamera()
```

4. 打开/关闭麦克风
```
//that为当前页面对象
that.setData({
  enableAudio: !this.data.enableAudio
});
```

5. 打开/关闭摄像头
```
//that为当前页面对象
that.setData({
  enableVideo: !this.data.enableVideo
});
```
