Vue+海康威视视频web插件开发
一、 环境准备
官网下载海康的Web端视频插件以及开发的Demo、文档
进入运行管理平台获取到 Appkey、AppSecret、Ip、Port
二、 引入文件
在index.html中引入插件文件
引入插件
三、 代码实现
批量预览list的数据格式如下
list = [ { cameraIndexCode: "", ezvizDirect: 0, gpuMode: 0, streamMode: 0, transMode: 1, wndId: 1 // 预览的窗口 }, { cameraIndexCode: "", ezvizDirect: 0, gpuMode: 0, streamMode: 0, transMode: 1, wndId: 2 } ]

<div :id="setting.id" :class="[oWebControl === null ? 'videoNull' : '']" v-html="oWebControl === null ? playText : ''"></div>
</div>
