摘　　要：嵌入式视频监控的方案设计已有众多论述,但针对实现过程中Linux下视频MPEG-4编码的驱动设计鲜有提及。本文以视频编码芯片IME6410的驱动设计为实例,主要论述了基于Video for Linux(V4L)规范的视频驱动实现方法,包括硬件接口、设备初始化、文件操作实现等,并着重分析了V4L规范、视频驱动及内核之间的内在联系。There are many researches on the design of embedded video surveillance system already. However, the method of design about Linux driver for MPEG-4 Codec has rarely been reported. In this paper, Linux driver for video Codec is discussed and an example of driver design for IME6410 is presented. The implement of driver based on V4L interface was introduced, of which the hardware interface, device initialization, file operations etc are involved as well. The fundamental relations between V4L interface, video dr...
