Ok, this fixed the issue:
brightness (int) : min=0 max=255 step=1 default=128
value=128
contrast (int) : min=0 max=255 step=1 default=128
value=128
saturation (int) : min=0 max=255 step=1 default=128
value=128
hue (int) : min=-128 max=127 step=1 default=0
value=0
volume (int) : min=0 max=65535 step=655 default=58880
value=65500 flags=slider
balance (int) : min=0 max=65535 step=655 default=32768
value=32750 flags=slider
bass (int) : min=0 max=65535 step=655 default=32768
value=32750 flags=slider
treble (int) : min=0 max=65535 step=655 default=32768
value=32750 flags=slider
mute (bool) : default=0 value=0
loudness (bool) : default=0 value=0
Also, v4l2-compliance is now complaining less about it.
Control ioctls:
fail: does not support V4L2_CTRL_FLAG_NEXT_CTRL
test VIDIOC_QUERYCTRL/MENU: FAIL
test VIDIOC_G/S_CTRL: OK
test VIDIOC_G/S/TRY_EXT_CTRLS: Not Supported
Standard Controls: 0 Private Controls: 0
(yet, it is showing "standard controls = 0").
Could you provide your SOB to the above patch?
Thanks!
Mauro
