You might try uvcdynctl that is what I have been using as it directly
talks to the webcam.
It will show the controls that exist and let you query and set them.
uvcdynctrl that is.
FWIW, uvcdynctrl seems to return much the same info as does v4l2-ctl. At least
for my capture device.
[egreshko@meimei ~]$ uvcdynctrl -c
Listing available controls for device video0:
Brightness
Contrast
Saturation
Hue
[egreshko@meimei ~]$ v4l2-ctl -l
brightness 0x00980900 (int) : min=-100 max=100 step=1
default=0 value=0
contrast 0x00980901 (int) : min=50 max=200 step=1
default=100 value=100
saturation 0x00980902 (int) : min=0 max=200 step=1
default=100 value=100
hue 0x00980903 (int) : min=-90 max=90 step=1
default=0 value=0
v4l2-ctl seems just a tad bit more user friendly since it returns the current
value for the controls.
