概述

MuPlayer 是百度音乐前端团队开发维护的浏览端音频播放内核,它基于HTML5 Audio及Flash音频技术,实现了多端通用(PC & WebApp)、浏览器兼容(ie6+、firefox、chrome、safari etc)及可扩展的多音频格式解码插件的音频文件播放功能,并在百度音乐多个线上产品线中应用,具备相当的灵活性和稳定性。

源码目录

muplayer/
  +src/             (源码)
    +demo.html      (一个完整的播放器demo示例)
  +lib/             (第三方库、工具及grunt编译等)
    +Gruntfile.js   (grunt配置)
    +bower.json     (demo运行需要安装的静态文件声明)
    +package.json   (grunt和bower等npm包的安装依赖声明)
  +doc/             (本地Demo及API文档)
  +test/            (qunit test)
  +dist/            (grunt编译后生成的最终引用文件)

签出源码并运行本地Demo

签出代码并安装必要依赖需执行:

curl https://raw.githubusercontent.com/Baidu-Music-FE/muplayer/lib/install.sh | sh

之后进入lib/目录并运行 grunt server [-p your port],可在 localhost 开启一个webserver。其中,-p为可选参数,可以指定server开启的端口(默认是7777):

cd muplayer/lib
grunt server

之后,便可以访问并查看 本地文档及Demo 了。

API详解

事件说明

在播放内核的实现中,事件的派发非常重要,这是解耦内核与UI交互的最佳方式 (客户端可自行监听需要的事件并做出相应的UI响应)。除上述部分API方法会派发诸如player:play,player:add等操作相关的事件外,下面还讲对播放状态相关的事件做一说明。 所有事件常量见 cfg.coffee 中的声明。默认对外派发的事件遵循精简且与HTML5 Auido规范统一的原则,player实例对外派发的事件点有三个:

  1. EVENTS.STATECHANGE 时,派发具体的change后的新状态。因此可以监听cfg.coffee中定义的所有STATES常量对应的状态。
  2. EVENTS.POSITIONCHANGE 时,会派发timeupdate事件。
  3. EVENTS.PROGRESS 时,会派发progress事件。 若以上均无法满足需求(在我们内部的产品中,还未曾遇到),可以进一步监听player.engine的相应事件。
