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/Channel…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

}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)
templatediv idvideo-contianervideoclassvideorefvideopreloadautoautoplayautoplaymutedwidth600height400/divclassmaskclickhandleClickVideo:class{ active-video-border: selectStatus }/div/div

import WebRtcStreamer from ../../public/hk/webrtcstreamerexport 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 somethingconsole.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.$refs.video,http://192.168.1.102:8000)//向后端发送rtsp地址this.webRtcServer.connect(this.rtsp)} catch (error) {console.log(error)}},/* 处理双击 单机 */dbClick() {this.clickCountif (this.clickCount 2) {this.btnFull() // 双击全屏this.clickCount 0}setTimeout(() {if (this.clickCount 1) {this.clickCount 0}}, 250)},/* 视频全屏 */btnFull() {const elVideo this.$refs.videoif (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()}},},
}
/scriptstyle scoped langscss
.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 四.其他功能
1.截图功能
rtsp流引入海康威视摄像头——截图功能-CSDN博客
到此为止海康摄像头引入vue的方法就完美完结了

最后祝大家事业蒸蒸日上,心想事成
