使用flv.js与video.js实现播放视频直播(简教程)

标签：

Node.js

1.准备

1.下载 nginx
2.下载 livego
3.下载 OBS
4.引用 flv.js
5.引用 video.js

(￣￣)／以上软件请大家自行解压或安装

2.环境配置

首先运行livego

运行livego效果

安装与运行OBS
打开设置配置流服务器

配置连接

连接成功后livego会有提示

提示

载入源

效果

进入nginx下的html目录,新建个index1.html与index2.html
然后运行 nginx (运行前自行修改nginx端口)

2.使用flv.js实现直播播放

之前我写过教程《flv.js简单使用示例》
吧之前的代码稍作修改

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;            margin-right: 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 class="lazyload" src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsQAAA7EAZUrDhsAAAANSURBVBhXYzh8+PB/AAffA0nNPuCLAAAAAElFTkSuQmCC" data-original="./flv.js/flv.min.js"></script>
    <script>
        var player = document.getElementById('videoElement');        if (flvjs.isSupported()) {            var flvPlayer = flvjs.createPlayer({                type: 'flv',                "isLive": true,//<====加个这个 
                url: 'http://127.0.0.1:7001/live/movie/a.flv',//<==自行修改

            });
            flvPlayer.attachMediaElement(videoElement);
            flvPlayer.load(); //加载
            flv_start();
        }        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>

访问http://127.0.0.1/index1.html

如果浏览器开始播放视频那说明你已经成功

效果

3.使用video.js实现直播播放(HLS)

根据livego教程

教程

那么 video.js 的播放地址应该是 http://127.0.0.1:7002/live/movie/a.m3u8

但是实际测试时失败了罒ω罒

所以就使用 ffmpeg 将RTMP转为HLS 放到nginx的html目录下

ffmpeg命令参考:

ffmpeg -i rtmp://127.0.0.1:1935/live/movie/a -c copy -f hls -hls_time 5.0 -hls_list_size 0 -hls_wrap 15 ../html/a.m3u8

ffmpeg

代码:
