基于v4l视频编程 ，在Linux环境下的 经过自己亲测试过很好用的源码，对库函数调用同时封装的很好，对变量以及函数的掉用关系有很多注释帮助我们可以很快v4l接口编程的知识ps:Makefile已经都写好了-V4l-based video programming under Linux environment after their parent tested well used source library function call and the package is very good, and the function of the variable swap with relations had a lot of comments to help us quickly v4l interface programming knowledgep，there have Makefile!
