一、简介
如果要让网页支持在所有浏览器上播放，就需要使用第三方的播放器。VideoJs是一个较好的播放器库，完全免费，不像JWPlayer一样需要付费才能使用一些高级功能。
videojs播放库是比较有名的一个播放库，它不仅支持hls也支持rtmp，不过如果是播放rtmp它最终也是通过flash插件完成的，我们暂时只看hls。
二、实现
如果使用videojs播放hls前端代码实现如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<link href="https://vjs.zencdn.net/7.6.6/video-js.css" rel="stylesheet" />
<!-- If you'd like to support IE8 (for Video.js versions prior to v7) -->
<script src="https://vjs.zencdn.net/ie8/1.1.2/videojs-ie8.min.js"></script>
</head>
<body>
<video
id="my-video"
class="video-js vjs-big-play-centered"
controls
preload="auto"
width="640"
height="264"
data-setup="{}">
<source src="http://192.168.12.187:8080/live/1.m3u8" type="application/x-mpegURL"/>
<p class="vjs-no-js">
请升级您的浏览器之后在看该视频!
<a href="https://videojs.com/html5-video-support/" target="_blank">支持H5视频标签</a>
</p>
</video>
<script src="https://vjs.zencdn.net/7.6.6/video.js"></script>
</body>
</html>
经过测试videojs播放HLS延迟大概在8s左右，不过也是非常的流畅，如果要定制自己的播放器可以参考如下代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>videojs自定义播放器</title>
<link href="./css/bootstrap.min.css" rel="stylesheet">
<script type="text/javascript" src="./js/jquery.min.js"></script>
<link href="./videojs/video-js.css" rel="stylesheet">
<script src="./videojs/video.js"></script>
<script src="./videojs/videojs-contrib-hls.min.js"></script>
</head>
<body>
<center>
<video id=example-video width=600 height=300 class="video-js vjs-default-skin" controls>
</video>
<div class="input-group" style="margin-top: 10px; width: 740px;">
<input type="text" name="stream_address" id="stream_address" required autofocus
placeholder="input HLS Stream Address 注意不要含有空格" class="form-control">
<span class="input-group-btn input-btn">
<button class="btn btn-default" id="form_button" type="button">提交</button>
</span>
</div>
</center>
<script type="text/javascript">

var player = videojs('example-video', options);

console.log(stream_address);
if (stream_address == "") {

msg.text("请输入媒体流地址");
msg.addClass("warning");
return false;
} else {
$('#stream_address').css("border", "1px #ff00ff solid");
msg.text("error");
msg.removeClass("warning");
}
$('#stream_address_code ').html("\"" + stream_address + "\"");
player.src({

});
console.log(stream_address);
