not available in buildroot. Right now I'm trying with OpenCV, as it is
documented on the Wiki.
some hours of work, I got something working ! Some ifdef in the OpenCV were
wrong, and I had to configure my kernel properly (the v4l / v4l2 distinction is
quite confusing !) and now I have 3 up to my 4 webcams working on our old
motherboard : the newest one has an USB 1.1 controller, which the cameras don't
support well, the older one has a USB 2.0 controller. If you want more details,
just ask !
