to install logitech orbit cam stuff


http://www.quickcamteam.net/documentation/how-to/how-to-install-the-webcam-tools

sudo aptitude install subversion cmake build-essential libxml2-dev pkg-config gengetopt

svn co http://svn.quickcamteam.net/svn/qct/webcam-tools/trunk

follow the instructions.  On my machine, the path turned out to be:
/usr/src/linux-source-2.6.32/drivers/media/video/uvc


usage of uvcdynctrl:

next make a directory,
cameraControl
and download the code from github
you will have to set the ROS_PACKAGE_PATH to find it

do the ususal rosmake stuff

run it when you have the skype capture program running and it will drive the camera

Right now it drives the camera attached to video0
we can change that, but I am too sleepy to do it right now!


results:

no camera plugged in:

dbarry@pad:~/logitech_camera_control/webcam-tools/build$ uvcdynctrl -l
Listing available devices:

OPTIONAL:
get luvcview:
svn co http://svn.quickcamteam.net/svn/luvcview

To compile luvcviewer, note that the README file has instructions, but it is somewhat out of date, so do this:
sudo apt-get install libsdl1.2-dev libsdl1.2debian  (was already present in my build)

find the following include files and copy then to the luvcviewer directory:
uvcvideo.h
dynctrl-logitech.h

on my system:
usr/src/linux-source-2.6.32/drivers/media/video/uvc/uvcvideo.h
/home/dbarry/logitech_camera_control/webcam-tools/common/include/dynctrl-logitech.h

in uvcvideo.h, around line 59, replace

struct uvc_xu_control {
    __u8 unit;
    __u8 selector;
    __u16 size;
    __u8 __user *data;
};

with:
struct uvc_xu_control {
    __u8 unit;
    __u8 selector;
    __u16 size;
//    __u8 __user *data;  <<<<<< remove __user:
    __u8 *data;
};

then run
make

then
sudo make install
which returned this:
install -s -m 755 -g root -o root luvcview /usr/local/bin
rm -f /usr/local/bin/uvcview

run it:
./luvcview

nice!
Now you have a nice interface for controlling all the camera functions
