Description: 我们在luvcview这个项目的基础上进行了修改，使之能够在s3c6410平台上运行，采用了6410特有的硬件空间色彩转换和图像缩放功能，也就是 post processor功能。
3 另外需要说一下我们修改后的luvcview可以运行在PC Linux平台和s3c6410平台，源码里面有两个makefile文件，一个针对嵌入式版本一个针对PC Linux版本，
嵌入式版本里面分硬件实现YUV to RGB和软件实现 YUV to RGB ，缺省配置是硬件实现YUV to RGB 及图像的缩放。
4 使用方法:
把 luvcview拷贝到 /mnt目录下面，执行 ./luvcview -d /dev/video2 -f jpg -s 800x600 在LCD屏幕上即可看到采集到的图像。
-d 指定摄像头的设备节点
-f 指定摄像头传给系统的数据格式，-jpg代表为 mjpeg 码流，另外还有 -yuv 这样传给系统的数据yuv422格式的码流。
-s 指定摄像头采集的分辨率为 800x600
如何查看您的摄像头支持的分辨率呢？
./luvcview -d /dev/video2 -L -We were modified on the basis of luvcview on this project, so that it can run on s3c6410 platform, using the 6410 unique hardware color space conversion and image scaling, that is, post processor function. 3 In addition we need to talk about luvcview modified to run on PC Linux platform and s3c6410 platform, there are two makefile source files, one for a PC Linux versions, an embedded version of which points for the hardware and the embedded version of YUV to RGB software YUV to RGB, the default configuration is implemented in hardware YUV to RGB and image scaling. 4 Usage: luvcview copied to the/mnt directory, ./luvcview-d/dev/video2-f jpg-s 800x600 on the LCD screen to see the images collected.-d Specifies the camera device nodes-f specified camera system to pass data format,-jpg representatives mjpeg stream, in addition to-yuv pass this data stream system yuv422 format.-s Specifies the camera capture resolution of 800x600 how to view your camera with a resolution of it? ./luvcview Platform: |
