视频采集功能,通过directshow技术能够捕获视频数据然后指定路径存储.avi格式的文件-Video capture function, through directshow technology to capture video data is then stored in the specified path. Avi format

在LINUX下用C语言编写的视频采集，之后保存到指定的路径上，已经通过编译，应该没有问题-In LINUX using C language under the video capture, and then saved to the specified path has been through the compiler, it should be no problem

yuv格式转换，从yuv420转换为yuv422sp格式，c语言编写，效率较高 需要指定转换的yuv420文件路径，输出yuv422sp文件-yuv420 to yuv422sp
