前言
对接海康视频插件v.1.5.2版本,实现摄像头视频在页面的显示,其对浏览器也有兼容发性的要求,其他的相关的内容可以看官方文档
一、首先下载视频web插件v.1.5.2版本
这里我用的api版本是v1.6.1,可以根据自己的需求选择,其次是下载视频WEB插件V1.5.2版本的视频插件
二、利用官方插件包进行相关需求开发
1.官方插件包和开发文档的下载
传送门:官方插件包和文档下载
2.在项目中引入插件包的相关的js
(1)下载完成后打开
打开bin文件安装:
(2)在项目中public文件下创建一个文件夹放视频插件js
3..new 一个WebControl 插件相关实例
(1)创建WebControl实例成功
cbConnectSuccess() {console.log('创建WebControl实例成功');oWebControl.JS_StartService('window', {// WebControl实例创建成功后需要启动服务dllPath: './VideoPluginConnect.dll', // 值"./VideoPluginConnect.dll"写死}).then(() => {// // 启动插件服务成功oWebControl.JS_SetWindowControlCallback({// 设置消息回调cbIntegrationCallBack: _that.cbIntegrationCallBack,});oWebControl.JS_CreateWnd(currentId).then(() => {//JS_CreateWnd创建视频播放窗口,宽高可设定_that.init(); // 创建播放实例成功后初始化});},() => {// 启动插件服务失败}).catch((err) => {console.log(err);});},
(2)创建WebControl失败
cbConnectError() {// 创建WebControl实例失败console.log('xxx');oWebControl = null;$('#' + currentId).html('插件未启动,正在尝试启动,请稍候...');window.WebControl.JS_WakeUp('VideoWebPlugin://'); // 程序未启动时执行error函数,采用wakeup来启动程序this.initCount++;if (this.initCount < 3) {setTimeout(function() {this.initPlugin();}, 3000);} else {$('#' + currentId).html('插件启动失败,请检查插件是否安装!');}},cbConnectClose(bNormalClose) {// 异常断开:bNormalClose = false// JS_Disconnect正常断开:bNormalClose = trueconsole.log('cbConnectClose');oWebControl = null;},
(3)浏览器调用WebControl实例完整
initPlugin() {let _that = this;let currentId = _that.newId " /> {// // 启动插件服务成功oWebControl.JS_SetWindowControlCallback({// 设置消息回调cbIntegrationCallBack: _that.cbIntegrationCallBack,});oWebControl.JS_CreateWnd(currentId).then(() => {//JS_CreateWnd创建视频播放窗口,宽高可设定_that.init(); // 创建播放实例成功后初始化});},() => {// 启动插件服务失败}).catch((err) => {console.log(err);});},cbConnectError() {// 创建WebControl实例失败console.log('xxx');oWebControl = null;$('#' + currentId).html('插件未启动,正在尝试启动,请稍候...');window.WebControl.JS_WakeUp('VideoWebPlugin://'); // 程序未启动时执行error函数,采用wakeup来启动程序this.initCount++;if (this.initCount < 3) {setTimeout(function() {this.initPlugin();}, 3000);} else {$('#' + currentId).html('插件启动失败,请检查插件是否安装!');}},cbConnectClose(bNormalClose) {// 异常断开:bNormalClose = false// JS_Disconnect正常断开:bNormalClose = trueconsole.log('cbConnectClose');oWebControl = null;},});this.oWebControl2 = oWebControl;},
4.初始化参数,其中secret参数需要通过RSA加密,加密公钥通过WebControl.JS_RequestInterface获取
首先通过appkey、secret、ip、port端口号等参数与服务器进行数据校验,校验通过即可正常与设备链接取流,初始化参数在步骤三创建窗口成功回调后执行,secret参数必须通过RSA进行加密处理,加密的公钥通过WebControl.JS_RequestInterface获取
//初始化init() {let _that = this;this.getPubKey(function() {// 请自行修改以下变量值var appkey = "XXXXX"; //综合安防管理平台提供的appkey,必填var secret = _that.setEncrypt("XXXXXXXXXX"); //综合安防管理平台提供的secret,必填var ip = "XXXXXXXX"; //综合安防管理平台IP地址,必填var playMode = 0; //初始播放模式:0-预览,1-回放var port = 443; //综合安防管理平台端口,若启用HTTPS协议,默认443var snapDir = ""; //抓图存储路径var videoDir = ""; //紧急录像或录像剪辑存储路径var layout = _that.layout; //playMode指定模式的布局var enableHTTPS = 1; //是否启用HTTPS协议与综合安防管理平台交互,这里总是填1var encryptedFields = "secret"; //加密字段,默认加密领域为secretvar showToolbar = 0; //是否显示工具栏,0-不显示,非0-显示var showSmart = 0; //是否显示智能信息(如配置移动侦测后画面上的线框),0-不显示,非0-显示var buttonIDs = ""; //自定义工具条按钮// 请自行修改以上变量值_that.oWebControl2.JS_RequestInterface({funcName: "init",argument: JSON.stringify({appkey: appkey, //API网关提供的appkeysecret: secret, //API网关提供的secretip: ip, //API网关IP地址playMode: playMode, //播放模式(决定显示预览还是回放界面)port: port, //端口snapDir: snapDir, //抓图存储路径videoDir: videoDir, //紧急录像或录像剪辑存储路径layout: layout, //布局enableHTTPS: enableHTTPS, //是否启用HTTPS协议encryptedFields: encryptedFields, //加密字段showToolbar: showToolbar, //是否显示工具栏showSmart: showSmart, //是否显示智能信息buttonIDs: buttonIDs, //自定义工具条按钮}),}).then((oData) => {_that.oWebControl2.JS_Resize(_that.width, _that.height); // 初始化后resize一次,能和盒子大小一致。if(_that.codeList.length > 0) {for(let code of _that.codeList) {_that.getVideoFun(code.cameraIndexCode)}}else {_that.getVideoFun(_that.code)}});});},// 设置窗口控制回调setCallbacks() {this.oWebControl.JS_SetWindowControlCallback({cbIntegrationCallBack: this.cbIntegrationCallBack,});},//获取公钥getPubKey(callback) {this.oWebControl2.JS_RequestInterface({funcName: "getRSAPubKey",argument: JSON.stringify({keyLength: 1024,}),}).then((oData) => {if (oData.responseMsg.data) {this.pubKey = oData.responseMsg.data;callback();}});},//RSA加密setEncrypt(value) {var encrypt = new window.JSEncrypt();encrypt.setPublicKey(this.pubKey);return encrypt.encrypt(value);},
5.通过WebControl 插件实例可以调用API方法操作功能
//视频预览功能getVideoFun(Code) {var cameraIndexCode = Code; //获取输入的监控点编号值,必填var streamMode = this.streamMode; //主子码流标识:0-主码流,1-子码流var transMode = 1; //传输协议:0-UDP,1-TCPvar gpuMode = 0; //是否启用GPU硬解,0-不启用,1-启用var wndId = -1; //播放窗口序号(在2x2以上布局下可指定播放窗口)cameraIndexCode = cameraIndexCode.replace(/(^\s*)/g, "");cameraIndexCode = cameraIndexCode.replace(/(\s*$)/g, "");this.oWebControl2 .JS_RequestInterface({funcName: "startPreview",argument: JSON.stringify({cameraIndexCode: cameraIndexCode, //监控点编号streamMode: streamMode, //主子码流标识transMode: transMode, //传输协议gpuMode: gpuMode, //是否开启GPU硬解wndId: wndId, //可指定播放窗口}),}).then((res) => {// console.log(res, "res");});},// 销毁播放窗口destroyVideoDiv() {this.oWebControl2.JS_DestroyWnd().then((data) => {console.log("销毁窗口成功");}).catch((err) => {console.log("销毁窗口失败");});},
