ar-play 拉流组件

ar-play组件从服务端拉取实时流。

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。

准备工作

注册微信小程序，登录小程序后台获取微信小程序appid，appSecrert，修改类目审核（社交、教育、医疗、政务民生、金融，目前只有这些支持），配置socket合法域名wss://域名:9095
获取开发者信息
开发-配置中开启“使用npm模块”，基础库选择2.4.0及以上，打开“不校验合法域名”、真机调试打开“调试”。集成miniprogram-ar-meet、miniprogram-ar-push、miniprogram-ar-play

使用说明

1.结合小程序会议SDK使用
2.结合小程序推流组件和小程序拉流组件使用

使用方法

安装 ar-play

npm install --save miniprogram-ar-play

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

{
  "usingComponents": {
    "ar-play": "miniprogram-ar-play"
  }
}

WXML 文件中引用 ar-play

<!-- 拉流组件 -->
<ar-play 
  id="{{pubID}}-play"
  data-id="{{pubID}}"
  enableAudio="{{enableAudio}}"
  playURL="{{playURL}}" 
  bindNetStateChange="handlePlayNetChange"
  bindPlayStatus="handlePlayStatus">
</ar-play>

组件可递归、可用view包裹自定义样式。例如：

<view wx:for="{{members}}" wx:key="index">
  <ar-play 
    id="{{item.pubID}}-play" 
    data-id="{{item.pubID}}"
    pubID="{{item.pubID}}" 
    playURL="{{item.playURL}}" 
    bindNetStateChange="handlePlayNetChange"
    bindPlayStatus="handlePlayStatus">
  </ar-play>
  <button data-id="{{item.pubID}}" bindtap="pause">暂停</button>
  <button data-id="{{item.pubID}}" bindtap="play">播放</button>
  <button data-id="{{item.pubID}}" bindtap="full">全屏</button>
</view>

ar-play的属性介绍如下：

|属性名|类型|默认值|是否必须|说明| |--|--|--|--|--|--| |id|String|-|是|用户获取组件的LivePlayerContext来暂停、播放等操作。| |playURL|String|-|是|ar-play组件拉流URL| |objectFit|String|contain|否|contain图像长边填满屏幕，短边区域会被填充⿊⾊; fillCrop图像铺满屏幕，超出显示区域的部分将被截掉| |orientation|String|vertical|否|画面方向：vertical竖直; horizontal水平| |enableAudio|Boolean|true|否|ar-play组件是否静音| |bindNetStateChange|Function|-|否|监听ar-play组件拉流网络质量| |bindPlayStatus|Function|-|否|ar-play组件播放状态的回调|
