原创 6410移植mjpg-streamer

mjpg-stream的移植需要jpeg的库，所以我们先移植jpeg的库

(1)jpeg库的移植

        1)jpeg源码包通过下面这个网址下载
                http://www.ijg.org/files/jpegsrc.v8b.tar.gz
                2)解压源码包
                tar xvf jpegsrc.v8b.tar.gz
                3)配置源码
                cd jpeg-8b
                ./configure --prefix=/home/6410/video/jpeg --host=arm-linux
                4)编译
                make
                5)安装
                make install
                6)拷贝libjpeg.s0.8库到开发板文件系统lib下中
 2)mjpg-stream的移植

        1)mjpg-stream源码包通过下面这个网址下载
                http://sourceforge.net/projects/mjpg-streamer/ 
                2)解压源码
                tar xvf mjpg-streamer-r63.tar.gz
                3)修改源码
                cd mjpg-streamer-r63
                修改顶层makefile及plugins目录中的各级makefile将所有
                CC=gcc
                修改为
                CC=arm-none-linux-gnueabi-gcc

        修改plugins/input_uvc/Makfile
                修改
                CFLAGS += -O2 -DLINUX -D_GNU_SOURCE -Wall -shared -fPIC
                为
                CFLAGS += -O2 -DLINUX -D_GNU_SOURCE -Wall -shared -fPIC -I/home/6410/video/jpeg/include
                修改
                $(CC) $(CFLAGS) -ljpeg -o $@ input_uvc.c v4l2uvc.lo jpeg_utils.lo dynctrl.lo
                为
                $(CC) $(CFLAGS) -ljpeg -L/home/6410/video/jpeg/lib -o $@ input_uvc.c v4l2uvc.lo jpeg_utils.lo dynctrl.lo
                4)编译
                make
                5)测试
                在开发板上mkdir /mjpeg
                拷贝*.so到开发板的mjpeg目录下，mjpg_streamer到开发板的bin下并改变权限

                打开开开发板运行
                mjpg_streamer -i "/mjpeg/input_uvc.so -d /dev/video2" -o "/mjpeg/output_http.so"
