Seen in "strace -s 256 -f luvcview -d /dev/video1".
open("/dev/video1", O_RDWR) = 7
ioctl(7, VIDIOC_QUERYCAP or VT_OPENQRY, 0x64a520) = 0
ioctl(7, VIDIOC_S_FMT or VT_RELDISP, 0x64a588) = -1 EINVAL (Invalid
argument)
close(7) = 0
write(1, "luvcview version 0.2.1 \nVideo driver: x11\nA window manager
is available\nvideo /dev/video1 \nUnable to set format: 22.\n Init v4L2
failed !! exit fatal \n", 150luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video1
Unable to set format: 22.
Init v4L2 failed !! exit fatal
) = 150
exit_group(1)
Problem with format.
Worked finally using "luvcview -f yuv -d /dev/video1".

Sid.
