使用条件
一、引入依赖文件
jsencrypt.min.js
jsWebControl-1.0.0.min.js //最新为 web-control_1.2.5.min.js 功能一样的
注意:
1、必须在 vue 的根 index.html 文件中引入, main.js 中引入无效;
2、jquery-1.12.4.min.js 文件只是demo中演示需要的依赖,不用引入;
相关文章介绍:传送门>>>
依赖文件及官网示例:下载>>>
插件API文档:查看
问的人多,下面是Vue2最新的demo配置对可以直接用的(2024/05/29)
最新demo:跳转下载>>>
二、 template
<div class="video-wrap mt-16">
<wrap
class="video-box"
v-for="(item, index) in realTimeData.videoConfig"
:key="item.id"
>
<div :id="`playWnd${index}`" class="playWnd"></div>
</wrap>
</div>
mounted
mounted() {
this.getDestruction()
this.getVideoCode()
window.addEventListener('resize', this.getDomInfo)
},
三、methods
/* 获取摄像头编码 */
async getVideoCode() {
this.realTimeData.videoLoad = true;
const params = {
area: "",
enterprise: this.realTimeData.enterpriseName,
street: "",
};
const { data } = await getCamera(params)
const videoCode = data.list.map(({ cameraIndexCode }) => ({
cameraIndexCode,
}));
this.realTimeData.videoConfig = videoCode.map((item) => {
return {
code: item.cameraIndexCode,
id: Math.floor(Math.random() * 100),
};
});
this.initPlugin(videoCode);
},
/* 创建插件实例 */
initPlugin(codeArr=this.realTimeData.videoConfig) {
const { width, height } = document.getElementById('playWnd0').getBoundingClientRect()
const dll = { dllPath: "./VideoPluginConnect.dll" };
codeArr.forEach((item, index) => {
let oWebControl = new WebControl({
szPluginContainer: `playWnd${index}`, // 指定容器id
iServicePortStart: 15900,
iServicePortEnd: 15909,
szClassId: "23BF3B0A-2C56-4D97-9C03-0CB103AA8F11", // 用于IE10使用ActiveX的clsid
cbConnectSuccess: () => {
oWebControl.JS_StartService("window", dll).then(() => {
oWebControl.JS_SetWindowControlCallback({
cbIntegrationCallBack: (msg) => {
//注:不能使用外部函数调用,无效
if (msg?.responseMsg?.msg?.result) {
const { result } = msg.responseMsg.msg;
if (result == 1024) {
oWebControl.JS_HideWnd();//放大隐藏其它视频窗口
} else if (result == 1025) {
oWebControl.JS_ShowWnd();//缩小显示全部窗口
}
}
},
});
//启动插件服务成功
oWebControl.JS_CreateWnd(`playWnd${index}`, width, height).then(() => {
//JS_CreateWnd创建视频播放窗口,宽高可设定
this.initVideo(oWebControl, item.cameraIndexCode); // 创建播放实例成功后初始化
});
});
},
//插件服务启动失败,尝试自行启动
cbConnectError: (err) => {
oWebControl = null
this.$message.warning(`监控插件未启动,正在尝试第${this.initCount + 1}次启动,请稍候...`);
WebControl.JS_WakeUp('VideoWebPlugin://')
this.initCount++
if(this.initCount < 3){
setTimeout(() => this.initPlugin(), 3000)
}else{
this.videoLoad = true;//打开下载提示,请先安装视频插件
}
},
});
this.plug.example.push(oWebControl);
});
},
/* 获取公钥 */
async initVideo(oWebControl, code) {
const params = {
funcName: 'getRSAPubKey',
argument: JSON.stringify({ keyLength: 1024 }),
}
const { responseMsg } = await oWebControl.JS_RequestInterface(params)
if (responseMsg.data) {
const pubKey = responseMsg.data
this.getVideoConfig(oWebControl,pubKey,code)
}
},
/* 视频插件配置 */
getVideoConfig(oWebControl,pubKey,code) {
const { appkey, secret, ip, port } = this.config
const configObj = {
funcName: 'init',
argument: JSON.stringify({
appkey: appkey, //API网关提供的appkey
secret: this.setEncrypt(secret,pubKey), //API网关提供的secret
ip: ip, //API网关IP地址
playMode: 0, //播放模式:0实时预览、1视频回放
port: +port, //端口,特别注意一定要是number类型,否则白屏
snapDir: 'D:\\SnapDir', //抓图存储路径
videoDir: 'D:\\VideoDir', //紧急录像或录像剪辑存储路径
layout: '1x1', //布局
enableHTTPS: 1, //是否启用HTTPS协议
encryptedFields: 'secret', //加密字段
showToolbar: 1, //是否显示工具栏
showSmart: 1, //是否显示智能信息
buttonIDs: '0,16,256,257,258,259,260,512,513,514,515,516,517,768,769', //自定义工具条按钮
}),
}
oWebControl.JS_RequestInterface(configObj).then(() => {
//这是是调div位置变化的,监听获取包裹div的位置变化再调用这个方法就行
this.getDomInfo()
this.getClickAction(oWebControl, code)
})
},
/* 视频流RSA加密 */
setEncrypt(value,pubKey) {
const encrypt = new JSEncrypt()
encrypt.setPublicKey(pubKey)
return encrypt.encrypt(value)
},
/* 获取div大小及位置 */
getDomInfo(oWebControl) {
const { width, height, top, left } = document.getElementById('playWnd0').getBoundingClientRect()
if (oWebControl) {
oWebControl.JS_Resize(width, height)
oWebControl.JS_CuttingPartWindow(left, top, 0, 0)
}else{
this.plug.example.forEach(item=>{
item.JS_Resize(width, height)
item.JS_CuttingPartWindow(left, top, 0, 0)
})
}
},
/* 视频播放 */
getClickAction(oWebControl, code) {
code = code.trim()
oWebControl.JS_RequestInterface({
funcName: 'startPreview',
argument: JSON.stringify({
cameraIndexCode: code, //监控点编号
streamMode: 0, //主子码流标识:0-主码流,1-子码流
transMode: 1, //传输协议:0-UDP,1-TCP
gpuMode: 0, //是否启用GPU硬解,0-不启用,1-启用
wndId: -1, //播放窗口序号(在2x2以上布局下可指定播放窗口)
}),
})
},
/* 销毁视频实例 */
getDestruction() {
if(this.plug.example.length){
this.plug.example.forEach((item) => {
item.JS_HideWnd()
item.JS_Disconnect().then((res) => {});
})
}
},
beforeDestroy
beforeDestroy() {
window.removeEventListener('resize', this.getDomInfo)
this.getDestruction()
},
beforeRouteEnter
//保险起见,如果页面开了keep-alive
beforeRouteEnter(to, from, next) {
next((vue) => vue.getDestruction())
},
四、使用效果图、功能:
1.实时监控 / 2.截图 / 3.录屏 / 4.摄像头控制 / 5.语音指挥(硬件支持)/ 6.即时回放
