海康威视有插件、无插件播放；webrtc直播；西瓜视频播放器；mpegts.js直播；flvjs直播

Notes 视频播放的几种方式

一、Video

1. mp4链接直接播放

二、海康威视3.3插件版直播、云台控制，资源下载地址

1. index.html引入hk文件中的js文件
2. 双击HCWebSDKPlugin.exe安装插件
3. 前端参照文件夹hkCamera中的示例代码
   

三、海康威视3.2无插件版直播，资源下载地址

1. 打开WEB无插件开发包_v3.2文件

2. 进入目录\WEB无插件开发包_v3.2\nginx-1.10.2\conf

3. 打开 nginx.conf

4. 可配服务IP及端口

        listen  9000;
        server_name  127.0.0.1;
   

5. 进入目录\WEB无插件开发包_v3.2\nginx-1.10.2，双击start.bat可开启nginx服务

6. 浏览访问 http://127.0.0.1:9000/cn/demo.html#/

7. demo.html 页面已根据实际情况做了修改，可嵌入iframe使用

8. 配合前端使用

    <iframe ref="iframe"
                class="iframe"
                src="http://127.0.0.1:9000/cn/demo.html#/"></iframe>
   
    const iframe = ref();
    function openVideoModal() {
        <!-- 与iframe通信，可做一定的延迟，因为要页面已加载，iframe页面才能监听到通信 -->
        if (iframe.value)
           iframe.value.contentWindow.postMessage({ type: 'play', cameraIp: '摄像机或录像机IP，可看demo.js中的配置', }, '*');
    }
    function closeVideoModal() {
        if (iframe.value)
            iframe.value.contentWindow.postMessage({ type: 'stop', }, '*');
    }
   

四、webrtc，资源下载地址

1. index.html引入，webrtc中的两个js文件

2. 前端

   1. 页面

        <template>
            <div :class="{ webrtcVideo: true, videoLoad: !videoLoadSuccess }">
                <video class="webrtcVideo"
                    :id="'video_' + videoUrl"
                    ref="videoRef"
                    autoplay
                    loop
                    muted
                    :controls="controls"></video>
            </div>
        </template>
      
        <script setup>
        import { onBeforeUnmount, onMounted, ref } from 'vue';
        import { Webrtc } from "./webrtc.js";
        defineExpose({ replay });
        const props = defineProps({
            <!-- rtsp://admin:wts12345@172.16.100.165:554/Streaming/Channels/101 -->
            videoUrl: {
                type: String,
                default: '',
                required: true,
            },
            controls: {
                type: Boolean,
                default: true,
                required: true,
            },
        });
        const videoRef = ref();
        const videoLoadSuccess = ref(false);
      
        function replay() {
            videoRef.value.load();
        }
      
        onMounted(() => {
            Webrtc.getInstance().connect(props.videoUrl);
      
            videoRef.value.addEventListener('loadedmetadata', function () {
                console.log('props.videoUrl----', "视频元数据加载完毕", props.videoUrl);
                videoLoadSuccess.value = true;
            }, true);
      
        });
        onBeforeUnmount(() => {
            Webrtc.getInstance().disconnect(props.videoUrl);
        });
        </script>
      
        <style lang='less' scoped>
        .webrtcVideo {
            width: 100%;
            height: 100%;
            object-fit: fill;
            position: relative;
            // background-color: red;
        }
      
        .videoLoad:before {
            content: '视频加载中...';
            position: absolute;
            top: 40%;
            left: 50%;
            transform: translate(-50%, -40%);
            color: #ffffff;
            font-size: 14px;
        }
        </style>
      

   2. 连接 webrtc.js

      export class Webrtc {
      constructor() {
      this.urlMap = new Map();
      }
      static instance;
      static getInstance() {
      if (!this.instance) {
      this.instance = new Webrtc();
      }
      return this.instance;
      }

        connect(rtspUrl, key) {
            let id = "video_" + rtspUrl; //对应元素id
      
            if (!rtspUrl) return;
      
            let webRtcServer = new WebRtcStreamer(id,`http://127.0.0.1:28000`);//对应推流服务运行命令中的ip:port
            console.log("webrtc  rtsp地址：" + rtspUrl);
            webRtcServer.connect(rtspUrl,null,"rtptransport=tcp",null);
            this.urlMap.set(id, webRtcServer);
        }
      
        disconnect(url) {
            let id = "video_" + url; //对应元素id
            let webrtc = this.urlMap.get(id);
            if (webrtc) webrtc.disconnect();
            this.urlMap.delete(id);
        }
      

      }

3. 推流服务
