【摘要】 H.264是新一代视频压缩标准,具有高的压缩效率、高质量的视频画面和良好的网络适应能力。DirectShow是一种基于COM技术的多媒体编程接口,是多媒体设计的一个非常好的框架。近年来,H.264视频压缩技术应用越来越广泛,但是DirectShow开发包里没有现成的H.264解码过滤器。因此,论文重点研究在DirectShow平台下H.264视频解码过滤器的设计与实现。首先,分析了DirectShow的架构和过滤器开发的一般思路;其次,根据过滤器的开发流程,结合当前的开源H.264解码库,设计并实现了H.264视频解码过滤器。测试结果表明解码性能稳定。更多还原

【Abstract】 H.264 is a new generation of video compression standard with high compression efficiency.It can achieve high quality of video screen and good ability to adapt to the network.DirectShow is a multimedia programming interface based on COM technology,which is a very good multimedia design framework.In recent years,H.264 video compression techniques was used more widely,the SDK of DirectShow absent h.264 decode filter.This paper focuses on the design and implementation of H.264 decoder filter based on DirectShow platform.Firstly,the construction of DirectShow technology is introduced while the general approach of development is analyzed.Secondly,the decoder filter of h.264 is designed and implemented,according to the development process combining with the open source code of h.264 decoder lib.The test result shows the performance of decoder filter is stable.更多还原
