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

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

index.html引入hk文件中的js文件
双击HCWebSDKPlugin.exe安装插件
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

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

可配服务IP及端口

     listen  9000;
     server_name  127.0.0.1;

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
浏览访问 http://127.0.0.1:9000/cn/demo.html#/
demo.html 页面已根据实际情况做了修改，可嵌入iframe使用

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

index.html引入，webrtc中的两个js文件

前端

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>

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);
  }

}

推流服务
1. 文档https://github.com/mpromonet/webrtc-streamer
2. 打开webrtc-streamer文件夹
3. 复制运行命令.txt中的命令，IP和端口可根据实际情况修改
4. 在webrtc-streamer-v0.8.4-dirty-Windows-AMD64-Release 文件目录下，运行上述命令

五、西瓜视频播放器 xgplayer v3.X

文档 https://h5player.bytedance.com/plugins/extension/xgplayer-flv.html#%E5%AE%89%E8%A3%85

             autoplay: true,
             fluid: true,//流式布局，可使播放器宽度跟随父元素的宽度大小变化
             plugins: [window.FlvPlayer],
         });
   }
   <!-- 销毁 -->

   let player = ref();
   function play(){
   if (mpegts.isSupported()) {
         let videoElement = document.getElementById('player1');
         player.value = mpegts.createPlayer({
             type: 'flv',
             isLive: true,
             url: "https://sf1-hscdn-tos.pstatp.com/obj/media-fe/xgplayer_doc_video/flv/xgplayer-demo-360p.flv"
         }, {
             liveBufferLatencyChasing: true,//开启追帧
             liveBufferLatencyMaxLatency: 0.9,//最大缓存时间
             liveBufferLatencyMinRemain: 0.2,//最小缓存时间
         });
         player.value.attachMediaElement(videoElement);
         player.value.load();

         // ------------------播放器的一些异常监听
         player.value.on(mpegts.Events.ERROR, (e) => {
             console.log('mpegts.Events.ERROR----发生异常', e);
         });
         player.value.on(mpegts.Events.LOADING_COMPLETE, (e) => {
             console.log('mpegts.Events.LOADING_COMPLETE----直播结束', e);
         });
         player.value.on(mpegts.Events.STATISTICS_INFO, (e) => {
             console.log('mpegts.Events.STATISTICS_INFO----解码帧', e.decodedFrames);
         });
     }
   }
   <!-- 销毁 -->
   function destroy(){
     player.value.destroy()
     player.value = null
   }

七、flv.js

安装 npm install --save flv.js

实现

   <!-- 播放容器 -->
   <div id="player1"></div>
   
   <!-- 播放 -->
   import flvjs from 'flvjs.js';
   let player = ref();
   function play(){
   if (flvjs.isSupported()) {
         let videoElement = document.getElementById('player1');
