介绍

在web开发中常常会遇到视频等媒体播放的问题，那么就需要一个好用的媒体播放器来提供基础技术支持，而clappr就很好的满足了我们的要求，它是一个Javascript实现的可扩展的Web媒体播放器，功能非常强悍，你可以在GitHub上查看它，下面我们就一起来看一看吧（下面只是截图）！

如何使用？

将Javascript标签引入html

<head>
 <script type="text/javascript" src="clappr.min.js"></script>
</head>

使用它创建一个播放器实例

<body>
 <div id="player"></div>
 <script>
 var player = new Clappr.Player({source: "url", parentId: "#player"});
 </script>
</body>

典型示例

由于clappr是可扩展的，所以会有一些非常不错的插件

360角度视频

npm install clappr clappr-video360

<script type="text/javascript" charset="utf-8" src="clappr.min.js"></script>
<script type="text/javascript" charset="utf-8" src="clappr-video360.min.js"></script>

var p = new Clappr.Player({
 source: 'url',
 plugins: {
 container: [Video360],
 },
 parentId: '#player',
});
// for better usability, disable clappr's click_to_pause plugin
p.getPlugin('click_to_pause').disable();

代码量很少就能实现一个类似于这样的功能

缩略图模式

<head>
 <script type="text/javascript" src="clappr.min.js"></script>
 <script type="text/javascript" src="clappr-thumbnails-plugin.js"></script>
</head>

var player = new Clappr.Player({
 source: "url",
 plugins: {
 core: [ClapprThumbnailsPlugin]
 },
 scrubThumbnails: {
 backdropHeight: 64,
 spotlightHeight: 84,
 thumbs: [
 	{time: 0, url: "url"},
 	{time: 2, url: "url"},
 	{time: 4, url: "url"}
 ]
 }
});

视频进度条标记

<head>
 <script type="text/javascript" src="clappr.min.js"></script>
 <script type="text/javascript" src="clappr-markers-plugin.js"></script>
</head>

var player = new Clappr.Player({
 source: "url",
 plugins: {
 core: [ClapprMarkersPlugin]
 },
 markersPlugin: {
 markers: [
 new ClapprMarkersPlugin.StandardMarker(0, "The beginning!"),
 new ClapprMarkersPlugin.StandardMarker(90, "Something interesting."),
 new ClapprMarkersPlugin.StandardMarker(450, "The conclusion.")
 ],
 tooltipBottomMargin: 17 // optional
 }
});

清晰度调整

<head>
 <script type="text/javascript" src="clappr.min.js"></script>
 <script type="text/javascript" src="level-selector.js"></script>
</head>

var player = new Clappr.Player({
 source: "url",
 plugins: [LevelSelector]
});

你还可以自定义标题等

var player = new Clappr.Player({
 source: "url",
 plugins: [LevelSelector],
 levelSelectorConfig: {
 title: 'Quality',
 labels: {
 2: 'High', // 500kbps
 1: 'Med', // 240kbps
 0: 'Low', // 120kbps
 },
 labelCallback: function(playbackLevel, customLabel) {
 return customLabel + playbackLevel.level.height+'p'; 
 }
 },
});

<head>
 <script type="text/javascript" src="clappr.min.js"></script>
 <script type="text/javascript" src="clappr-stats.min.js"></script>
 <script type="text/javascript" src="clappr-nerd-stats.min.js"></script>
</head>
<body>
 <div id="player"></div>
 <script>
 window.player = new Clappr.Player({
 parentId: '#player',
 plugins: [ClapprNerdStats, ClapprStats],
 // source: 'url',
 source: 'url',
 height: 607.5,
 width: 1080,
 clapprNerdStats: {
 // Optional: provide multiple combination of keyboard shortcuts to show/hide the statistics.
 // Default: ['command+shift+s', 'ctrl+shift+s']
 shortcut: ['command+shift+s', 'ctrl+shift+s'],
 // Optional: position of the icon to show/hide the statistics.
 // Values: 'top-right', 'top-left', 'bottom-right', 'bottom-left', 'none'
 // Default: 'top-right'
 iconPosition: 'top-right'
 }
 })
 </script>
</body>

总结

clappr的最大优点就在于起扩展性，你可以在其基础上通过插件的方式实现更多有趣和实用的功能，而且你还可以自定义UI，或许会给你带来一些惊喜！
