前言

海康视频插件v.1.5.2版本运行环境需要安装插件VideoWebPlugin.exe,对浏览器也有兼容性要求,具体看官方文档

功能

1. 摄像头的预览与停止预览

2. 窗口布局设置

3. 页面多次调用组件唯一性

4. 初始单个预览与多个预览

5. 组件窗口自适应

6. 双击窗口全屏

对应下载插件

海康官网下载插件 里面有dome等其他需要用到的

地址:

安装插件

打开下载的文件里的bin文件 安装一下VideoWebPlugin

vue脚手架中集成插件

把官方资源包里的query-1.12.4.min.js、jsencrypt.min.js、web-control_1.2.5.min.js复制到vue项目public目录下,在index.html引入js

封装组件(vue2)

        代码:

<!-- 
	只实现预览摄像头功能
	方法调用
	预览监控点的方法调用 可以传值 值为监控点
	this.$refs.hikVideo.previewVideo('333');
	停止全部预览
	this.$refs.hikVideo.stopAllPreview();
	窗口布局
	this.$refs.hikVideo.setLayout('1x1');
	注意:
		如果要实现 点击播放摄像头 前提是组件已经在页面显示出来
		例子:
			this.$refs.hikVideo.previewVideo(data); data为监控点编号
 -->

组件使用:

先引入这个组件到项目页面

<template>
	<div>
		<div class="monitor-main">
			<HikVideo
				:wsUrl="cameraIndexCode"
				:objData="HKobjData"
				ref="hkplayer"
			></HikVideo>
		</div>
		<button @click="previewVideo">预览视频</button>
		<button @click="stopAllPreview">停止所有预览</button>
		<el-select
			v-model="value"
			placeholder="设置布局"
			size="large"
			style="width: 240px"
			@change="setLayout"
		>
			<el-option
				v-for="item in options"
				:key="item.value"
				:label="item.value"
				:value="item.value"
			/>
		</el-select>
	</div>
</template>
<script setup>
import HikVideo from './largeScreen/components/VideoMain.vue'
import { ref } from 'vue'

const cameraIndexCode = ref('') // 摄像头索引code
const HKobjData = ref({
	// 海康初始化数据
	appkey: '', //综合安防管理平台提供的appkey,必填
	ip: '', //综合安防管理平台IP地址,必填
	secret: '', //综合安防管理平台提供的secret,必填
	port: 443, //综合安防管理平台端口,若启用HTTPS协议,默认443
	playMode: 0, // 0 预览 1回放
	layout: '1x1', //页面展示的模块数【16】
	showToolbar: 1 //是否显示工具栏,0-不显示,非0-显示
})

const hkplayer = ref(null)

const value = ref('1x1')

const options = [
	{ value: '1x1' },
	{ value: '2x2' },
	{ value: '3x3' },
	{ value: '4x4' },
	{ value: '4+9' },
	{ value: '1+1+12' },
	{ value: '1+16' }
]

const previewVideo = () => {
	console.log('预览视频')
	// 预览视频 传参(参数为摄像头索引code)
	hkplayer.value.previewClick('')
}
const stopAllPreview = () => {
	console.log('停止所有预览')
	hkplayer.value.stopAllPreview()
}

const setLayout = (e) => {
	console.log(e)
	hkplayer.value.setLayout(e)
}
</script>
<style>
.monitor-main {
	width: 600px;
	height: 400px;
}
</style>
