Android下OpenMax IL框架的研究和应用

由于Android系统多媒体引擎使用的是OpenMax软件解码组件,出现了播放分辨率较高视频不流畅的问题。为此,提出在Android系统上设计一OpenMax硬件解码组件,并将其放在嵌入式开发平台上进行测试。该组件是在对Android系统自带Open-Max IL层进行研究的基础上,以SamSung S3C6410为嵌入式核心处理器,针对MPEG-4视频流而设计。实验结果表明,设计的硬件解码组件优于系统自带的软件解码组件,表明该方案切实可行。

RESEARCH AND APPLICATION OF OPENMAX IL FRAMEWORK BASED ON ANDROID

Due to the use of OpenMax software decoding component in Android multimedia engine system,there arises the problem of less smooth when playing high resolution video.Therefore,we propose to design an OpenMax hardware decoding component on Android system,and test it on the embedded development platform.The component is designed for the MPEG-4 video streams using SamSung S3C6410 as its embedded core processor based on the research on OpenMax IL layer in Android system.Experimental results show that the designed hardware decoding component outperforms the software decoding component the android system comes with,this indicates that the program is practical and feasible.
