I've download the usb_cam in my BBB and catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --pkg usb_cam in my workplace ( indigo ). But I meet some issue when I catkin_make_isolated it

So I've download the files below :

sudo apt-get install libv4l1-dev

sudo apt-get install libyaml-cpp-dev

sudo apt-get install v4l-utils

After installing these lib, it allows me to catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release --pkg usb_cam

But when I run

rosrun usb_cam usb_cam_node

root@beaglebone:~/indigo# rosrun usb_cam usb_cam_node

[ INFO] [1400120763.231818383]: using default calibration URL

Kind Regards,

You use a usb camera or a web camera? And if you use a usb camera usb_cam is ok But if you use a web camera , usb_cam might not work well. I guess you usb a web camera as your device is /dev/video0
