[mythtv-users] howto store ivtv brightness settings

Each time /dev/video1 starts recording it changes the brightness
setting to be too dark.  See the bottom is 178 instead of 128.  If i
manually change it back to 128, the next records sets it right back to
178.  Any idea how to make this stay at 128?  Is there a table this is
stored within myth?


tv1 ~ # ivtvctl -Y -d /dev/video0
ioctl: VIDIOC_QUERYCTRL
Brightness = 128
Contrast = 63
Saturation = 63
Hue = 0
Volume = 58880
Balance = 32768
Bass = 32768
Treble = 32768
Mute = 0
