| |
For changes to V4L2_CID_CONTRAST and V4L2_CID_SATURATION, the value is checked by "if (ctrl->value < 0 || ctrl->value > 127)" yet the maximum value in v4l2_queryctrl is set to 255 for both of these items. This means that programs (like MythTV) which set the contrast and saturation to the midvalue (127) get *full* contrast and saturation. (It's not pretty.)
Setting the maximum values to 127 solves this problem.
Please copy me on responses.
Thank you.
