Something is wrong?

[satgit62]

Hello,

I was wondering if I should make this change to be able to calibrate the LUT under webOS?

#518 (comment)

_lutCalibrator->incomingCommand(_instanceManager->getRootPath(), (_videoGrabber != nullptr) ? _videoGrabber->grabberWrapper() : nullptr, getActiveComponent(), checksum, _startColor, _endColor, limitedRange, saturation, luminance, gammaR, gammaG, gammaB, coef);

[awawa-dev]

Yes, if the grabber is excluded from build process completely (for example: webOS) then this patch is necessary. You can re-open PR and I will merge it later.
