flv.js简单使用示例

Flv.js 是由 bilibili 网站开源的 HTML5 Flash 视频（FLV）播放器，纯原生 JavaScript 开发（ECMAScript 6 编写），没有用到 Flash。
它的工作原理是 Flv.js 在 JavaScript 中流式解析 flv 文件流，并实时转封装为 fmp4 ，通过 Media Source Extensions 喂给浏览器，实现了 FLV 格式视频的播放。

如果你已经安装了nodejs可以使用 npm来安装 flv.js
当然你也可以使用其他方式进行下载
在下载好的文件夹中找到dist文件夹中的flv.min.js复制出来

可以使用简单的服务器测试

简单html测试代码：

<!DOCTYPE html>
<html>

<head>
    <meta content="text/html; charset=utf-8" http-equiv="Content-Type">
    <title>flv.js demo</title>
    <style>
        .mainContainer {
    display: block;
    width: 1024px;
    margin-left: auto;
    margin-right: auto;
}

.urlInput {
    display: block;
    width: 100%;
    margin-left: auto;
    margin-right: auto;
    margin-top: 8px;
    margin-bottom: 8px;
}

.centeredVideo {
    display: block;
    width: 100%;
    height: 576px;
    margin-left: auto;
    margin-right: auto;
    margin-bottom: auto;
}

.controls {
    display: block;
    width: 100%;
    text-align: left;
    margin-left: auto;

    </style>
</head>

<body>
    <div class="mainContainer">
        <video id="videoElement" class="centeredVideo" controls autoplay width="1024" height="576">Your browser is too old which doesn't support HTML5 video.</video>
    </div>
    <br>
    <div class="controls">
        <!--<button onclick="flv_load()">加载</button>-->
        <button onclick="flv_start()">开始</button>
        <button onclick="flv_pause()">暂停</button>
        <button onclick="flv_destroy()">停止</button>
        <input style="width:100px" type="text" name="seekpoint" />
        <button onclick="flv_seekto()">跳转</button>
    </div>
    <script src="flv.min.js"></script>
    <script>
        var player = document.getElementById('videoElement');
        if (flvjs.isSupported()) {
            var flvPlayer = flvjs.createPlayer({
                type: 'flv',
                url: '你的视频.flv'
            });
            flvPlayer.attachMediaElement(videoElement);
            flvPlayer.load(); //加载
        }

        function flv_start() {
            player.play();
        }

        function flv_pause() {
            player.pause();
        }

        function flv_destroy() {
            player.pause();
            player.unload();
            player.detachMediaElement();
            player.destroy();
            player = null;
        }

        function flv_seekto() {
            player.currentTime = parseFloat(document.getElementsByName('seekpoint')[0].value);
        }
    </script>
</body>

</html>

React测试代码：

以下getFlvVideoStreamApi为接口地址,根据自己返回视频流或mp4文件格式来调整即可

// 获取直播视频流
  const goVideo = async (params: any) => {
    getFlvVideoStreamApi(params)
      .then((res) => {
        if (res && res.code === 200 && res.data) {
          let player = videoRef.current;
          let suffix = (res.data.url || '').split('.');
          (window as any).flvPlayer?.destroy(); //一定要做销毁
          if (suffix[suffix.length - 1] === 'flv') {
            if (flvjs.isSupported()) {
              // flvjs: https://github.com/Bilibili/flv.js/blob/master/docs/api.md
              (window as any).flvPlayer = flvjs.createPlayer({
                type: 'flv',
                isLive: true,
                enableWorker: true,
                enableStashBuffer: false,
                stashInitialSize: 128,
                // 空流：'https://monitorpull.roombox.xdf.cn/719d1ad9ea2dd0c806f26cd82de07adc/719d1ad9ea2dd0c806f26cd82de07adc1134397e7d62576fba305003a812237f.flv'
                url: res.data.url, // res.data
              });
              (window as any).flvPlayer.attachMediaElement(player);
              (window as any).flvPlayer.load(); //加载
              (window as any).flvPlayer.pause();
            } else {
              console.error('not support flv file');
            }
          } else if (suffix[suffix.length - 1] === 'mp4') {
            (window as any).flvPlayer = flvjs.createPlayer({
              type: 'mp4',
              url: res.data.url,
            });
            (window as any).flvPlayer.attachMediaElement(player);
            (window as any).flvPlayer.load(); //加载
            (window as any).flvPlayer.pause();
          }
        }
      })
      .catch((err) => console.error(err, 'video err'));
  };

DOM：

<video
    ref={videoRef}
    controls
    autoPlay
    width="100%"
    height="488"
    style={
   
   {
        width: `${videoFixed ? '400px' : '100%'}`,
        height: `${videoFixed ? '288px' : '488px'}`,
    }}
>
    Your browser is too old which doesn't support HTML5 video.
</video>

其他方法规整：

video元素：const videoRef = useRef<HTMLVideoElement>(null);

flvjs引入： <script type="text/javascript" src="<%= context.config.publicPath +'flvMin.js'%>"></script>
也可以引入线上的flv.min.js
