gspca驱动移植介绍
gspca webcam drivers 是linux下摄像头支持的最广泛的一个驱动, 这是由一个法国医生(http://mxhaard.free.fr/)所设计编写的.不过从2007年底开始,已经不再维护, 最后一个版本为20071224.
ubuntu中可以在通过apt-get install gspca-source安装代码, 不过此代码再2.6.26以上内核会编译出错.
而从lwn.net(http://lwn.net/Articles/291054/)得知, 从2.6.26开始, gspca已经合并到内核中间,
名称为UVC(USB Video Class Linux device driver), 在driver/media/video/gspca目录. 编译时只需勾选相关的模块即可.
如果想使用最新的gspca代码可以从以下几个站点下载到:
http://linuxtv.org/hg/~jfrancois/gspca/
http://linuxtv.org/hg/~eandren/gspca-m5602/
http://linuxtv.org/hg/~pinchartl/uvcvideo/
建议下载最新的gspca代码, 可能修正了最新的bug.
# wget http://linuxtv.org/hg/~jfrancois/gspca/archive/tip.tar.bz2 -O gspca.tar.bz2
# tar -jxvf gspca.tar.bz2
# cd gspca-xxx
# make menuconfig # 选择编译选项
# make
# make install
使用usb camera插入时即可自动加载模块, 可通过v4l-info命令查看/dev/video相关信息.
# v4l-info
测试摄像头可用以下几个软件:
webcam
luvcview
spcaview
camorama
通过 aptitude install xxx 即可
示例:
# lucview -d /dev/video0 -L
