I have the same problem with you; and i have checked the source code of the libuvc_camera package, I guess it is the problem of the configure of the video_mode. In the source code it didn't set the video_mode as the launch file, but set it with a fixed value: "UVC_COLOR_FORMAT_UNCOMPRESSED". But i'm not sure.

where did you get the libuvc_camera package, i do the same command as you, and it make successfully; but the followed command confused me;
when i type the command: rosrun libuvc_camera , and then 'tab' to complete the command automatic, it comes out that :rosrun libuvc_camera UVCCamera.cfg ... I don't know why

Hi: I'm new to ROS system, and i have a problem when using the libuvc_camera package; below are my steps:

  1. Firstly, clone the libuvc_camera from https://github.com/ktossell/libuvc_ros
  2. commands in the consol : cd libuvc_camera ; mkdir build; cd build; cmake .. ; make ; sudo make install
  3. commands: source devel/setup.bash
  4. then if i run the command: rosrun libuvc_camera camera_node; it display messages : couldn't found executable file camera_node in libuvc_camera ; found libuvc_camera/build/devel/lib/libuvc_camera/camera_node but it is not a executable file;
    and when i use the tab; it display commands: rosrun libuvc_camera UVCCamera.cfg
    can somebody tell me what is the problem ? thanks!
