摘　　要：基于PC/104 plus架构的MPEG-4视频压缩卡目前国内外没有成熟产品,已有产品的软件开发包占用硬件资源太多,原因在于没有基于微软DirectShow技术设计;针对以上技术难点,优化设计,提出基于微软DirectShow技术和MPEG-4编解码芯片vw2010的视频压缩模块的SDK设计方案;SDK软件开发包中利用DirectShow技术和多线程同步技术实现视频压缩卡的实时预览,使视频播放更加流畅并提高软件开发包的性能及效率,解决了已有产品占用硬件资源太多的问题;该软件开发包已经成功应用于瑞泰凯博科技有限公司的产品VFG7610ER,并实现量产,经用户使用性能表现优异。MPEG-4 video compression hoards based on PC/104 plus architecture are currently not mature at home and abroad. The Software Development Kit of exiting products took up too much hardware resource, because there was no technical design based on Microsoft DirectShow. To solve the above technical difficulties, proposed the SDK design of video compression module based on DirectSbow technology and MPEG-4 compression chip vw2010. The method to achieve preview based on DirectShow and multi--threading synchronization technology was proposed in SDK, which made more fluid the video preview and improved performance and efficiency of software. The SDK has been successfully applied to VFG7610ER of RTKB Co. products, and volume production, excellent performance by user.
