摘要
Flash是Adobe推出的PC平台主流的多媒体格式标准和产品,但Adobe一直没有推出应的嵌入式解决方案。为了解决Flash格式动画文件在各种嵌入式设备上的播放问题,基于开源的GNU Gnash flash解决方案,实现了flash动画文件在ARM嵌入式Linux平台的播放。分析了Gnash系统的组成结构,研究了其各个功能模块的实现技术以及与其他模块和操作系统平台的关系。然后针对嵌入式系统主频低、内存小的特点,对Gnash的功能模块进行裁剪,去掉了ActionScript引擎等动画播放不需要的交互式部分功能,并在基于ARM的Intel XSCALE PXA270嵌入式linux平台实现了Gnash系统。
Adobe Flash is a multimedia format standard in PC. However, Adobe has not provided a solution in embedded platform. In order to play Flash file in embedded device, this paper uses Gnash which is a GUN open source Flash solution to play Flash file in ARM embedded Linux. It analyses ~he framework of gansh. It also researches various functional modules and discusses the relations between functional modules and operating system platform. Because embedded environment has low clock speed and limited memory, the paper cuts off some Gnash＇s modules, e.g. interactive modules, which is not mandatory while ActionScript engine plays movies. And the Gnash is run in the Intel PXA270 Linux platform successfully.
