摘　　要：强大的多媒体功能已经成为衡量智能电视性能的重要标准。MooPlayer系统是基于Android平台改进设计的,重新设计OpenMAX层,将组件串接(tunning)在一起,完善数据通道,加快数据处理过程,并通过Handle消息机制,实现模块间的异步控制。同时,开发出能支持更多媒体格式、具有强解码功能、广泛协议支持以及高解码效率的多媒体框架,弥补Android自身在多媒体框架方面的不完善,解决StageFright源码中能够支持的媒体格式种类有限、解码效率低的问题。测试结果表明,该MooPlayer播放器系统兼容性强,具备稳定的播放功能,解码效率高且能够支持更多的媒体格式,满足用户需求。Powerful multimedia function is an important standard to measure the performance of smart TV. The design of the MooPtayer system is based on the Android platform . The OpenMAX layer is redesigned, the component is connected in series （tunning） together, the channels data is improved to accelerate the process of data processing, and through the Handle message mechanism the asynchronous inter module control is realized. Meanwhile, the multimedia framework is exploited, which can support more multimedia formats, with strong decoding functions, extensive protocol support. The system can make up for the imperfect Android native multimedia framework, which solves the problem of limited media format and low decoding efficiency in StageFright source code. The results show that the MooPlayer player system has strong compatibility, stable playback function, high decoding efficiency and can support more media formats to meet user needs.
