I have used Brown University's probe driver to get my builtin webcam
publishing in ROS. Since it uses gstreamer, it should work with pretty
much any webcam that can be used in Ubuntu.<br>

Harmish,<br>
<br>
I have had good results using the usb_cam driver on my Logitech
Quickcam Pro.<br>
<br>
I did not have to edit the source code, but I did need to provide a new
pixel format as a parameter. Try using this launch file:<br>
<br>
<launch><br>
<node pkg="usb_cam" type="usb_cam_node" name="cam"><br>
<param name="video_device" value="/dev/video0"/><br>
<param name="pixel_format" value="yuyv"/><br>
</node><br>
<br>
</launch><br>

<br>
i am trying hard to make logitech quickcam pro 4000 to work with ros. i
have tried following drivers without sucess.<br>
<br>
gencam_cu - problem to link wiht libroslib.o - recompiling does not
solve the problem !!<br>
logitech_usb_webcam - making does not give any executable<br>
usb_cam - has problems with ioctl(fd, VIDIOC_S_FMT, &fmt) - gives
error 22 - invalid parameters<br>
uvc_cam - has problems with ioctl(fd, VIDIOC_S_FMT, &fmt) - gives
error 22 - invalid parameters - i succeed in bypassing these errors by
changing fmt.fmt.pix.pixelformat to V4L2_PIX_FMT_YUV420 and changing
buffersize (NB_BUFFER = 2), however now i have segmentation fault<br>
<br>
if anybody have success running a webcam with ros, i would be thankful
to know the driver and camera you are using.<br>
<br>
cheers,<br>
harmish.<br>
