Hello All:
I own a laptop with a webcam supported by the uvc driver. I can use it for
videoconference successfully but I fail to take an single jpg photo. I use
luvcview 0.2.1 in order to have it, with no success.
I have just built the latest svn driver (r188), with same result. I'm on a
Debian unstable distro using 2.6.24.2 for and Core2 Duo laptop. This is the
output of luvcview:
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
Unable to set format: 22.
Init v4L2 failed !! exit fatal
Same result for luvcview -w, -c, -C and -S . -g fails since direct I/O is
not supported.
What does this message mean? Is there a way I could get a simple
screenshot using the driver. Pointers are appreciated.
Only -f yuv worked, but well, what about the others?
I've also tried some other parameters. This is their output:
luvcview -L
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
/dev/video0 does not support read i/o
