Description

Android自带多媒体播放器的功能扩展方法和多媒体播放系统
【技术领域】
本发明涉及Android技术领域，特别是涉及一种Android自带多媒体播放器的功能扩展方法和多媒体播放系统。
【背景技术】
随着Android（安卓）技术的发展，Android系统已普遍应用在智能电子设备中，特别是智能手机。在Android系统的智能电子设备中，该智能电子设备本身都会设有Android自带多媒体播放器，可通过Android自带多媒体播放器进行播放多媒体文件。其中，Android自带多媒体播放器通过安卓播放器JAVA （计算机编程语言）接口层接入多媒体文件；并通过JAVA 本地接口调用播放器库Mediaplayer(libmedia)提供对JAVA的接口；播放器库对上层的JAVA 本地接口提供播放器类的接口；播放服务器（MediaPlayer Service）是媒体的服务器，其通过继承播放器库的类实现服务器的功能，并通过调用底下的核心来完成播放作业。
但是，AOSP（Android Open-Source Project ，Android 开放源代码项目）不允许对Android Code（代码）进行大的改动，使得Android自带多媒体播放器本身的媒体能力比较弱。在面临多类型数据格式的网络时代，Android自带多媒体播放器只能播放自带多媒体播放器所支持的数据格式的多媒体文件，不能播放其他额外数据格式的多媒体文件，容易减低用户的体验。
【发明内容】
本发明主要解决的技术问题是提供一种Android自带多媒体播放器的功能扩展方法和多媒体播放系统，能够解决多媒体播放器的媒体能力薄弱的问题。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种Android自带多媒体播放器的功能扩展方法，该方法包括：在Android操作系统注册一个不同于Android自带多媒体播放器的扩展多媒体播放器；在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类；通过衍生类指定扩展多媒体播放器针对播放目标进行多媒体播放。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种多媒体播放系统，其包括播放服务器和扩展多媒体播放器，播放服务器包括注册单元和衍生类生成单元，其中：注册单元用于在Android操作系统注册一个不同于Android自带多媒体播放器的扩展多媒体播放器；衍生类生成单元用于在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类，并通过衍生类指定扩展多媒体播放器针对播放目标进行多媒体播放。
本发明的有益效果是：区别于现有技术的情况，本发明的Android自带多媒体播放器的功能扩展方法通过在Android操作系统注册一个不同于Android自带多媒体播放器的扩展多媒体播放器；然后在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类；并通过衍生类指定扩展多媒体播放器进行多媒体播放，能够通过扩展多媒体播放器播放Android自带多媒体播放器不支持的数据格式的多媒体文件，大大提升多媒体播放器的媒体能力，有效提升用户的体验。

【具体实施方式】
下面结合附图和实施方式对本发明进行详细说明。
如图1所示，图1是本发明Android自带多媒体播放器的功能扩展方法的流程示意图。该方法包括以下步骤：
步骤S101：在Android操作系统注册一个不同于Android自带多媒体播放器的扩展多媒体播放器。
在本实施例中，扩展多媒体播放器用于播放第一数据格式集所支持的数据格式的多媒体文件，Android自带多媒体播放器用于播放第二数据格式集所支持的数据格式的多媒体文件，第二数据格式集与第一数据格式集所支持的数据格式不同。其中，第一数据格式集包括但不限于avi（Audio Video Interleaved，音频视频交错格式）、wmv（Windows Media Video，微软公司推出的一种流媒体格式）、asf（Advanced Streaming Format， 高级串流格式）、mov（苹果公司开发的一种音频、视频文件格式）、mpg（一种影音文件格式）、mpeg（Moving Picture Experts Group，动态图像专家组）、rm（一种流媒体视频文件格式）、flv（Flash Video，一种新的视频格式）和ape（数字音乐无损压缩格式）。第二数据格式集包括但不限于3gp（3G流媒体的视频编码格式）、mp2格式、mp3格式、mp4格式、ts（高清电影封装格式）、flac（无损音频压缩编码）、ogg（一种新的音频压缩格式）、mkv（一种新的多媒体封装格式）、webm（一种开放、免费的媒体文件格式）和wav（微软公司开发的一种声音文件格式）。应理解，在另一实施例中，第一数据格式集可以包含第二数据格式集，或第一数据格式集包含部分第二数据格式集中的数据格式。
优选地，多媒体文件为音频文档、图像文档或视频文档。当然，本发明的多媒体文件并不限定于音频文档、图像文档或视频文档，也还可以是其他的多媒体文件。
步骤S102：在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类。具体而言，如图2所示，步骤S102包括以下子步骤：
步骤S1021：在Android操作系统新增一个继承于Android播放器JAVA接口层的衍生类。
步骤S1022：在Android安装包中导入衍生类。
其中，本发明的衍生类中加入接口setFlag()，可通过该接口setFlag()设置标识符。并且重写父类(Android播放器JAVA接口层)中的接口setDataSource()，以使衍生类在调用父类的接口setDataSource()时将指定播放器的标识符，并一并传下去至下层的播放核心。此外该标识符被加入至等待播放的多媒体文件的播放路径前。
步骤S103：通过衍生类指定扩展多媒体播放器针对播放目标进行多媒体播放。具体而言，如图3所示，步骤S103包括以下子步骤：
步骤S1031：由衍生类的接口setFlag()设置对应扩展多媒体播放器的标识符。其中标识符设置有预设值，预设值包括第一预设值、第二预设值或第三预设值等等。例如，第一预设值为6。
该标识符用于标识该扩展多媒体播放器，使得该扩展多媒体播放器区别于Android系统中自带的多媒体播放器。将扩展多媒体播放器的标识符添加至播放目标（即多媒体文件）的地址之前，以形成该播放目标的播放路径。形成该播放目标的播放路径后，调用Android播放器JAVA接口层的接口setDataSource()把指定播放器的标识符一并依次传至JAVA本地接口、播放器库、播放服务器、扩展多媒体播放器和Android自带多媒体播放器。
在本实施例中，预先在Android操作系统设置第一数据格式集，该第一数据格式集与标识符的预设值对应，即Android操作系统能够自动识别第一数据格式集与标识符对应的值。如Android操作系统识别播放目标的数据格式为第一数据格式集中的数据格式时，将扩展多媒体播放器的标识符添加至播放目标的地址之前，以形成该播放目标的播放路径。
步骤S1032：扩展多媒体播放器解析播放路径中的标识符，从而使得扩展多媒体播放器生成播放对象。应理解，扩展多媒体播放器和Android自带多媒体播放器都解析播放路径中的标识符。
具体来说，当Android自带多媒体播放器与扩展多媒体播放器都收到等待播放的播放目标的播放路径时，Android自带多媒体播放器与扩展多媒体播放器都解析该播放路径。当扩展多媒体播放器通过解析播放路径中的标识符，解析结果为匹配时，则使用该扩展多媒体播放器生成播放对象。换言之，此时已选定使用扩展多媒体播放器来播放播放目标，并且扩展多媒体播放器已做好播放准备。当Android自带多媒体播放器通过解析播放路径中的标识符，解析结果为匹配时，则使用该Android自带多媒体播放器生成播放对象；此时已选定使用Android自带多媒体播放器来播放播放目标，并且Android自带多媒体播放器已做好播放准备。
步骤S1033：利用扩展多媒体播放器播放播放对象并显示第一显示信息。其中，第一显示信息包括但不限定于音频信息、视频信息或亮度信息。
进一步地，如图4所示，在多媒体播放器播放多媒体文件时，包括以下步骤：
步骤S201：多媒体播放器解析播放路径中的标识符。应理解，此处是Android自带多媒体播放器和扩展多媒体播放器解析播放路径中的标识符。
步骤S202：判断标识符对应的值是否为第一预设值。
在确定标识符对应的值为第一预设值时，执行步骤S203：调用扩展多媒体播放器播放多媒体文件。即，在Android操作系统中生成播放对象，并设置播放对象的第一显示信息；并利用扩展多媒体播放器播放播放对象并显示第一显示信息。
步骤S204：扩展多媒体播放器接收并执行控制指令。其中控制指令包括暂停播放指令、继续播放指令、停止播放指令、重新播放指令以删除指令中的至少一种。
在确定标识符对应的值不为第一预设值时，此刻说明多媒体文件的数据格式为Android自带多媒体播放器所支持的数据格式，则执行步骤S205：利用Android自带多媒体播放器播放多媒体文件。即，在Android操作系统中设置播放对象，并设置播放对象的第二显示信息；同时利用Android自带多媒体播放器播放播放对象并显示第二显示信息。其中，第二显示信息包括但不限定于音频信息、视频信息或亮度信息。
步骤S206：Android自带多媒体播放器接收并执行控制指令。其中控制指令包括暂停播放指令、继续播放指令、停止播放指令、重新播放指令以删除指令中的至少一种。
本实施例通过在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类，并通过此衍生类指定扩展多媒体播放器进行多媒体播放，能够提升多媒体播放器的媒体能力，有效提升用户的体验。
本发明还公开一种多媒体播放系统，如图5所示，图5是本发明多媒体播放系统的第一结构示意图，图5中的多媒体播放系统与图1中的方法对应。多媒体播放系统包括Android播放器JAVA接口层11、扩展接口层12、JAVA本地接口13、播放器库14、播放服务器15、扩展多媒体播放器16和Android自带多媒体播放器17。
Android播放器JAVA接口层11用于接入Android多媒体应用开发。
扩展接口层12用于接入扩展多媒体播放器所支持数据格式的多媒体应用开发。应理解，扩展接口层12与图1中的衍生类是相同物件的不同角度表述。
JAVA本地接口13用于调用播放器库提供对JAVA的接口。
播放器库14用于对JAVA本地接口13的JAVA 本地接口提供播放器类的接口。
播放服务器15是媒体的服务器，其通过继承播放器库的类实现服务器的功能，并通过调用底下核心的扩展多媒体播放器16和Android自带多媒体播放器17来完成播放作业。
在本发明另一实施例中，如图6所示，多媒体播放系统另包含了注册单元151和衍生类生成单元152。
注册单元151用于在Android操作系统注册一个不同于Android自带多媒体播放器的扩展多媒体播放器。
衍生类生成单元152用于在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类。具体而言，如图7所示，衍生类生成单元152包括衍生类增加子单元1521和衍生类导入子单元1522。衍生类增加子单元1521用于在Android操作系统新增一个继承于Android播放器JAVA接口层的衍生类。衍生类导入子单元1522用于在Android安装包中导入衍生类，以使得衍生类指定扩展多媒体播放器16针对播放目标进行多媒体播放。
所述多媒体播放器中的衍生类的接口setFlag()设置对应扩展多媒体播放器的标识符。其中标识符设置有预设值，预设值包括第一预设值、第二预设值或第三预设值等等。例如，第一预设值为6。该标识符用于标识该扩展多媒体播放器16，使得该扩展多媒体播放器16区别于Android系统中Android自带的多媒体播放器17。扩展接口层12与Android播放器JAVA接口层11也形成了一个播放路径形成单元，将该扩展多媒体播放器16的标识符被添加至播放目标的地址之前，以形成该播放目标的播放路径。形成该播放目标的播放路径后，调用Android播放器JAVA接口层11的接口setDataSource()把指定播放器的标识符一并依次传至JAVA本地接口13、播放器库14、播放服务器15、扩展多媒体播放器16和Android自带多媒体播放器17。
在本实施例中，预先在Android操作系统设置第一数据格式集，该第一数据格式集与标识符的值对应，即Android操作系统能够自动识别第一数据格式集与标识符对应的值。如Android操作系统识别播放目标的数据格式为第一数据格式集中的数据格式时，将扩展多媒体播放器16的标识符添加至播放目标的地址之前，以形成该播放目标的播放路径。
扩展多媒体播放器16用于解析播放路径中的标识符。应理解，扩展多媒体播放器16和Android自带多媒体播放器17分别用于解析播放路径中的标识符，从而使得扩展多媒体播放器16或Android自带多媒体播放器17生成播放对象。
具体来说，当Android自带多媒体播放器17与扩展多媒体播放器16都收到等待播放的播放目标的播放路径时，Android自带多媒体播放器17与扩展多媒体播放器16都解析该播放路径。当扩展多媒体播放器16通过解析播放路径中的标识符，解析结果为匹配时，则使用该扩展多媒体播放器16生成播放对象。换言之，此时已选定使用扩展多媒体播放器16来播放播放目标，并且扩展多媒体播放器16已做好播放准备。当Android自带多媒体播放器17通过解析播放路径中的标识符，解析结果为匹配时，则使用该Android自带多媒体播放器17生成播放对象；此时已选定使用Android自带多媒体播放器17来播放播放目标，并且Android自带多媒体播放器17已做好播放准备。
如图8所示，扩展多媒体播放器16包括解析单元161、标识符判断单元162和执行单元163。解析单元161用于解析播放路径中的标识符。标识符判断单元162用于判断标识符对应的值是否为第一预设值。执行单元163用于在确定标识符对应的值为第一预设值时，调用扩展多媒体播放器16播放多媒体文件。即，执行单元163在Android操作系统中生成扩展多媒体播放器16对应的播放对象，并设置播放目标的第一显示信息，同时利用扩展多媒体播放器16播放播放目标并显示第一显示信息。其中，第一显示信息包括但不限定于音频信息、视频信息或亮度信息。另外，执行单元163还用于接收并执行控制指令，其中控制指令包括暂停播放指令、继续播放指令、停止播放指令、重新播放指令以删除指令中的至少一种。
如图9所示，Android自带多媒体播放器17包括解析单元171、标识符判断单元172和执行单元173。解析单元171用于解析播放路径中的标识符。标识符判断单元172用于判断标识符对应的值是否为第一预设值。执行单元173用于在确定标识符对应的值不为第一预设值时，调用Android自带多媒体播放器17播放多媒体文件。即，执行单元173在Android操作系统中生成Android自带多媒体播放器17对应的播放对象，并设置播放对象的第二显示信息，同时利用Android自带多媒体播放器17播放播放对象并显示第二显示信息。其中，第二显示信息包括但不限定于音频信息、视频信息或亮度信息。另外，执行单元173还用于接收并执行控制指令，其中控制指令包括暂停播放指令、继续播放指令、停止播放指令、重新播放指令以删除指令中的至少一种。
本实施例的多媒体播放器通过在Android操作系统中设置一个继承于Android播放器JAVA接口层的衍生类，并通过此衍生类指定扩展多媒体播放器进行多媒体播放，能够提升多媒体播放器的媒体能力，有效提升用户的体验。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
