摘要
传统的CMOS和CCD摄像头生成的视频文件体积庞大,若直接存储将占用很大的存储空间和传输带宽,给文件的存储和传输带来极大的不便。S3C6410处理器不仅支持摄像头输入,而且拥有支持MPEG-4视频编解码的协处理器。WinCE的DirectShow是一个强大的流媒体处理架构,通过各种功能不同的滤波器来实现视频的采集和压缩。因此使用SC6410处理器的WinCE系统实现视频的压缩处理,MPEG-4视频压缩滤波器的设计成为关键,该设计对此进行了深入研究,并展示其性能。
A large of raw video files is generated by the traditional CMOS and CCD camera, which stored in the original uncompressed file is bound to take up much storage space and transmission bandwidth. The S3C6410 processor not only supports camera input, but also supplies MPEG--4 video compressor for video compression which offers a perfect hardware platform. DireetShow based on WinCE is a powerful streaming media processing architecture. The video acquisition and compression is performed by a variety of different functions . To perform video compression on wince based on S3C6410 Processor, the design of MPEG-4 filter is a key link. The design method is introduced and the application effect and performance is shown.
