USB cameras

[Kevin Gordon]

Mr. W:

We have had lots of success doing simple things using uvc compliant cameras
on 1.5 using both cheese and guvcview on Build 883.

Our use is mainly for microscopes, but for all intents and purposes they
are 'a camera'.

Mikus did a lot of work for us to help getting the guvcview parameters part
set up if you want to use that as the control mechanism.  If cheese is good
enough, it  works pretty well right out of the box, as long as the USB
device is recognized by the XO as a compliant USB camera.  Total effort on
the gnome side:  Yum install cheese.  Plug the microscope in after boot,
dmesg and lsusb will tell you in advance if it has been recognized.  If it
is, start cheese, select the camera device and have fun.  Better for stills
than video, sometimes a stutter in the video stream. Especially problematic
if you also have a USB2VGA adapter plugged in and are using an external
monitor.  It seems to freeze regularly in that case

O, and since lsusb doesn't ship by default you may have to yum install
usbutils too, to get that beast.

We haven't done the 12.1.0 testing yet, but can accelerate that if you'd
like us to.

Cheers

KG
