Hi friends,
It is not a problem now.
I've succeed in playing video from my USB web camera by importing highgui of OpenCV now.
Maybe when vidl2 is OK, we can back to it. But it is very convenient to visit cameras by OpenCV. I hope that vidl2 will be more convenient and powerful.
Best Regards,

Currently, I don't know much about code to grab images in vxl. vidl can
read video from file, but there is a vidl2 developement going on in
contrib/brl/bbas/vidl2 that is intended to handle live video feeds (usb
camera, firewire, etc.) as well as video from file. However, it is in
it's early developement and, particularly, the live camera code is still
under developement. There is other code like the cmu1394 support in vvid
that you could take a look at.

I would suggest visiting the package documentation and browsing for a
while to familiarize yourself with what is available at:


You can use the first link to search the packages. But again, what you
are looking for is on-going work being consolidated and developed in vidl2.
