Description

媒体播放方法、装置和计算机存储介质 技术领域
本发明涉及通信领域，具体而言，涉及一种媒体播放方法、装置和计算机存储介质。
背景技术
随着移动互联网的迅猛发展，OTT(Over The Top)技术的推广以及各种智能终端设备的出现，通过手机、掌上电脑、机顶盒等视频终端在线收看视频，成为人们越来越普遍的休闲娱乐方式。
Android OTT机顶盒的音视频播放功能大都是基于多媒体框架实现的，例如安卓的多媒体框架。而大多数的多媒体框架原声的播放器主要有MidiFile、StagefrightPlayer、NuPlayer。MidiFile Player主要负责midi音频文件的播放，StagefrightPlayer主要用来播放本地文件，NuPlayer主要用来网络文件播放，包括超文本传输协议(HyperText Transfer Protocol，简称为HTTP)LiveSource和实时流传输协议(Real Time Streaming Protocol，简称为RTSP)Source两个source，目前主要支持RTSP和http这两种协议文件的播放。
而交互式网络电视(Internet Protocol Television，简称为IPTV)机顶盒发展到现在已经比较成熟了，对应播放器支持的传输协议比较完善：网络组管理协议(Internet Group Management Protocol，简称为IGMP)、RTSP、HTTP、和实时传输协议(Real-time Transport Protocol，简称为RTP)等协议都支持。另外，IPTV上支持的前向纠错码(Forward Error Correction简称FEC)、自动误差矫正(Automatic Error Request，简称为ARQ)恢复，频道快切(fast channel change，简称为FCC)、组播和时移相互切换等功能， 目前安卓多媒体框架上原生的播放器都是不支持的。
针对相关技术中，某些操作系统(例如，安卓系统)里不支持IPTV播放器来播放媒体的问题，尚未提出有效的解决方案。
发明内容
本发明实施例提供了一种媒体播放方法、装置和计算机存储介质。
本发明实施例的一个方面，提供了一种媒体播放方法，包括：获取操作系统中待播放的媒体；根据所述操作系统中扩展的交互式网络电视IPTV播放器来播放所述待播放的媒体。
本发明实施例的另一个方面，还提供了一种媒体播放装置，包括：第一获取模块，配置为获取操作系统中待播放的媒体；播放模块，与所述获取模块连接，配置为根据所述操作系统中扩展的交互式网络电视IPTV播放器来播放所述待播放的媒体。
本发明实施例还提供、一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于前述媒体播放方法。
通过本发明实施例，通过根据操作系统中扩展的IPTV播放器来播放待播放的视频的技术方案，解决了相关技术中，例如安卓系统等操作系统里不支持IPTV播放器来播放媒体的问题，提出了一种将IPTV播放器快速融合到多媒体框架的方法，扩充多媒体框架的协议支持和数据质量恢复功能。

在一个可选示例中，图3为根据本发明实施例的媒体播放装置的另一结构框图，如图3所示，上述装置还包括：扩充模块24，与上述播放模块22连接，配置为在安卓系统的播放器中扩充一个指定类，其中，该指定类用于支持交互式网络电视IPTV播放器的播放器功能。
为了更好的实现播放模块22的功能，如图3所示，播放模块22还可以包括：
获取单元220，配置为获取待播放的媒体的统一资源定位符URL；判断单元222，与获取单元220连接，配置为根据URL判断上述待播放的视频是否需要IPTV播放器播放；播放单元224，与判断单元222连接，配置为在需要IPTV播放器播放时，根据IPTV播放器来播放上述安卓系统中待播放的媒体。
图4为根据本发明实施例的媒体播放装置的又一结构框图，如图4所示，上述装置，还包括：第二获取模块26，配置为获取待播放的媒体的播放数据；预处理模块28，与第二获取模块26连接，配置为对播放数据进行播放预处理，上述装置，还包括：发送模块30，与预处理模块28连接，配置为将经过播放预处理后的播放数据发送至解码器，其中，该解码器根据上述经过播放预处理后的播放数据进行媒体播放。
在本发明实施例中，上述预处理模块的播放预处理包括：前向纠错FEC、频道快切FCC。
为了更好的理解上述媒体播放过程，以下结合实施例对上述技术方案进行说明，如下所述：
本发明优选实施例一能尽量复用IPTV播放器的系统框架和代码，完成 OTT机顶盒对IPTV功能的支持，缩短软件开发周期。
首先，简单介绍一下安卓多媒体框架的核心MediaPlayer，如图5所示，在各个库中，l ibmedia.so位于核心的位置，它对上层的提供的接口主要是MediaPlayer类，类libmedia_jni.so通过调用MediaPlayer类提供对JAVA的接口，并且实现了android.media.MediaPlayer类。
libmediaplayerservice.so是Media的服务器，它通过继承libmedia.so的类实现服务器的功能，而libmedia.so中的另外一部分内容则通过进程间通讯和libmediaplayerservice.so进行通讯。libmediaplayerservice.so的真正功能通过调用StageFrighterPlayer来完成。
基于安卓原生框架的播放命令时序：建立数据源(setdatasource)、准备(prepare)、开始(start)、停止(stop)。
本实施例实现的大致流程可如下：
1、在MediaPlayer中扩充一个IptvAgent类(相当于上述实施例中的指定类)，与Nuplayer和stagefright平级，用来支持IPTV播放器的功能，这个IptvAgent充当一个播放器代理的角色，如图6所示，IptvAgent和安卓原生播放器，与播放器控制模块之间通过事件反馈的形式完成交互过程，这里IptvAgent可以充当一个播放器代理的角色。
2、在setdatasource阶段，根据URL区分，对适合的节目选择IptvAgent进行播放。
3、在IptvAgent中完成安卓多媒体框架播放接口和IPTV播放器的对外接口的转换与对接。
4、在IptvAgent中完成IPTV播放器上报事件和安卓多媒体框架标准事件的转换。
在另一个实施中，所述实现大致流程可包括：
步骤1：IPTV播放器可以是一个独立的进程，也可以以一个动态库方式存在；
步骤2：安装包(APK)下发播放消息，setdadatasource接口中携带的是一个组播地址；
步骤3：在libmediaplayerservice.so中根据url，选择IptvAgent播放器进行播放；
步骤4：IptvAgent发送播放消息给IPTV播放器，真正进行媒体播放，具备FEC、FCC等功能；
步骤5：IPTV播放器下载数据，进行数据预处理(比如FEC，FCC等)；
步骤6：IPTV播放器将数据送给解码器进行播放。
需要说明的是，上述步骤的顺序并不用来限定本发明优选实施例一的任何顺序，只是用来解释本发明优选实施例一所涉及到的技术方案。
综上所述，本发明实施例可用于解决了相关技术中，安卓系统里自带的播放器支持的协议有限进而无法支持IPTV媒体播放的问题，提出了一种将IPTV播放器快速融合到安卓多媒体框架的方法，扩充安卓多媒体框架的协议支持和数据质量恢复功能。
在另外一个实施例中，还提供了一种软件或可执行程序，该软件或可执行程序用于执行上述实施例及优选实施方式中描述的技术方案。
在另外一个实施例中，还提供了一种存储介质，该存储介质中存储有上述软件或可执行程序，该存储介质包括但不限于：光盘、软盘、硬盘、可擦写存储器等。例如，本实施例提供一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执前述任意一个媒体播放方法的至少其中之一，例如可执行图1所示的方法。所述计算机存储介质可为非瞬间存储介质。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第 一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的对象在适当情况下可以互换，以便这里描述的本发明的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，凡按照本发明原理所作的修改，都应当理解为落入本发明的保护范围。
