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

vue2使用rtsp视频流接入海康威视摄像头(纯前端)插图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vue2使用rtsp视频流接入海康威视摄像头(纯前端)插图(4)

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vue2使用rtsp视频流接入海康威视摄像头(纯前端)插图(5)

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() {
/**

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)


这里要注意两个地方

第一个是vue2使用rtsp视频流接入海康威视摄像头(纯前端)插图(9)

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

vue2使用rtsp视频流接入海康威视摄像头(纯前端)插图(14)

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!
