想在TomatoARM中配置网络摄像头，罗技的C270
根据

这篇文章修改了makefile文件并编译成功。
运行
./mjpg_streamer -i "/jffs/camera/input_uvc.so --help"
（input_uvc使用了绝对路径）返回了这样的错误。
MJPG Streamer Version.: 2.0
ERROR: could not find input plugin
Perhaps you want to adjust the search path with:
# export LD_LIBRARY_PATH=/path/to/plugin/folder
dlopen: File not found
就算export LD_LIBRARY_PATH也没有用。
但是与此同时，这样做是可以正确返回帮助信息的
./mjpg_streamer -i "/jffs/camera/input_testpicture.so --help"
MJPG Streamer Version.: 2.0
Help for input plugin..: TESTPICTURE input plugin
The following parameters can be passed to this plugin:
[-d | --delay ]........: delay to pause between frames
[-r | --resolution]....: can be 960x720, 640x480, 320x240, 160x120
input_init() return value signals to exitroot@unknown:/jffs/camera#
载入了5个模块，lomod可以看到这样的信息

应该是有找到设备。
就是input_uvc.so的问题，文件明明就在那里，可是不管怎么做都是提示File not found，很费解，在这请教各位大大了
