一.获取海康威视rtsp视频流

海康威视官方的RTSP最新取流格式如下:

rtsp://用户名:密码@IP:554/Streaming/Channels/101

用户名和密码

IP就是登陆摄像头时候的IP(笔者这里IP是192.168.1.210)

所以笔者的rtsp流地址就是rtsp://用户名:密码@192.168.1.210:554/Streaming/Channels/101

二. 测试rtsp流是否可以播放

1.实现RTSP协议推流需要做的配置

1.1关闭萤石云的接入

1.2调整视频编码为H.264

2.安装VLC播放器

在此下载 video mediaplay官网 即（VLC）

安装完成之后 打开VLC播放器

在VLC播放器中打开网络串流 输入rtsp地址

成功的话我们可以看到我们所显示的摄像头

如果RTSP流地址正确且取流成功，VLC的界面会显示监控画面。否则会报错，报错信息写在了日志里，在[工具]>[消息]里可以看到

三.在vue2中引用rtsp视频流形式的海康摄像头

1.新建webrtcstreamer.js文件

在public文件夹下新建webrtcstreamer.js 代码贴在下方,复制粘贴即可

var WebRtcStreamer = (function() {

this.srvurl = srvurl || location.protocol+"//"+window.location.hostname+":"+window.location.port;

2.下载webrtc-streamer

资源在最上面

也可以去github上面下载：webrtc-streamer

下载完解压,打开文件夹,启动webrtc-streamer.exe

​

打开完会出现cmd一样的黑框框如下

​

如果没有启动成功可以在浏览器中输入http://127.0.0.1:8000/查看本地端口8000是否被其他应用程序占用，如果没有被占用打开窗口应该如下图所示(是可以看见自己的页面的)

​

3.封装组件video.vue(名字随意)

代码如下(但是有需要注意的地方，请看下方)

<template>

<div id="video-contianer">

<video

class="video"

ref="video"

preload="auto"

autoplay="autoplay"

muted

width="600"

height="400"

/>

<div

class="mask"

@click="handleClickVideo"

:class="{ 'active-video-border': selectStatus }"

></div>

</div>

</template>

<script>

import WebRtcStreamer from '../../public/hk/webrtcstreamer'

export default {

name: 'videoCom',

props: {

rtsp: {

type: String,

required: true,

},

isOn: {

type: Boolean,

default: false,

},

spareId: {

type: Number,

},

selectStatus: {

type: Boolean,

default: false,

},

},

data() {

return {

socket: null,

result: null, // 返回值

pic: null,

webRtcServer: null,

clickCount: 0, // 用来计数点击次数

}

},

watch: {

rtsp() {

// do something

console.log(this.rtsp)

this.webRtcServer.disconnect()

this.initVideo()

},

},

destroyed() {

this.webRtcServer.disconnect()

},

beforeCreate() {

window.onbeforeunload = () => {

this.webRtcServer.disconnect()

}

},

created() {},

mounted() {

this.initVideo()

},

methods: {

initVideo() {

try {

//连接后端的IP地址和端口

this.webRtcServer = new WebRtcStreamer(

this.$refs.video,

`http://192.168.1.102:8000`

)

//向后端发送rtsp地址

this.webRtcServer.connect(this.rtsp)

} catch (error) {

console.log(error)

}

},

/* 处理双击 单机 */

dbClick() {

this.clickCount++

if (this.clickCount === 2) {

this.btnFull() // 双击全屏

this.clickCount = 0

}

setTimeout(() => {

if (this.clickCount === 1) {

this.clickCount = 0

}

}, 250)

},

/* 视频全屏 */

btnFull() {

const elVideo = this.$refs.video

if (elVideo.webkitRequestFullScreen) {

elVideo.webkitRequestFullScreen()

} else if (elVideo.mozRequestFullScreen) {

elVideo.mozRequestFullScreen()

} else if (elVideo.requestFullscreen) {

elVideo.requestFullscreen()

}

},

/*

ison用来判断是否需要更换视频流

dbclick函数用来双击放大全屏方法

*/

handleClickVideo() {

if (this.isOn) {

this.$emit('selectVideo', this.spareId)

this.dbClick()

} else {

this.btnFull()

}

},

},

}

</script>

<style scoped lang="scss">

.active-video-border {

border: 2px salmon solid;

}

#video-contianer {

position: relative;

// width: 100%;

// height: 100%;

.video {

// width: 100%;

// height: 100%;

// object-fit: cover;

}

.mask {

position: absolute;

top: 0;

left: 0;

width: 100%;

height: 100%;

cursor: pointer;

}

}

</style>

这里要注意两个地方

第一个是

第二个是

不会查看本机端口的看这里(首先使用 Win + R打开运行 输入cmd)

4.使用video封装组件播放rtsp视频流

首先我们在要使用video封装组件的地方引入并且注册video组件

之后在页面中使用video组件 并且定义了两个变量将rtsp流传给封装的video组件

效果图如下

5.使用此种方法播放的时候会默认带声音播放,如何取消(看这里)

之后声明一个方法

然后在created里面调用就静音了

到此为止海康摄像头引入vue的方法就完美完结了

如果同学们有什么好的意见或者有什么问题可以私信我

最后祝大家事业蒸蒸日上,心想事成！
