uvcapture and luvcview both fail.
Running Gentoo with kernel-2.6.17-r4 and have emerged the
linux-uvc-0.0.1_pre41 ebuild.
The machine has 2 tv cards so the camera device is /dev/video2
$ luvcview -v -d /dev/video2
uvcview verion 0.1.6
Video driver: x11
A window manager is available
video /dev/video2
The camera light shows red but the screen is black. Closing the window
gives "Stop asked" on the console, but after that the process hangs. Have to
use kill -9 to stop luvcview.
---
With the -g option, luvcview gives an i/o error.
$luvcview -d /dev/video2 -g -f jpg -s 640x480
uvcview verion 0.1.6
size width: 640 height: 480
Video driver: x11
A window manager is available
video /dev/video2
/dev/video2 does not support read i/o
Init v4L2 failed !! exit fatal

'uvccapture' doesn't fare any better.
$uvccapture -v -d /dev/video2
Using videodevice:
Saving images to: snap.jpg
Image size: 320x240
Taking snapshot every 0 seconds
Taking images using mmap
