嵌入式视频采集存储电路的设计

摘要

该文介绍了嵌入式Linux的视频采集压缩存储功能的实现。以三星S3C2440为核心处理器,移植嵌入式Linux操作系统。利用Linux下视频采集库函数V4L2实现视频采集,利用开源编解码器xvid实现视频压缩,并将压缩的视频存储到SD卡中。%This paper introduces the realization of embedded Linux video capture,compression and stor- age.The system uses Samsung S3C2440 processor as the core and has been transplanted embedded Linux OSJt uses video capture library function which named V4L2 to realize video capture and uses an open source codec XviD to compress the video,The compressed video is finally stored to the SD card.
