Adjusting image parameters in Delphi (Mitov VideoLab)

Question

I made a little application in Delphi XE3, using Mitov VideoLab. I have VLDSCapture component which captures the video from my webcam. Also I have VLDSImageDisplay component to display the captured preview. What I want to do, is adjust i.e. Brightness, i.e. on each click of the button to increase Brightness for 10. I can access the VLDSCapture1.Adjustment.Brightness.Value, but when I increase it using this line on button click:

VLDSCapture1.Adjustment.Brightness.Value := VLDSCapture1.Adjustment.Brightness.Value + 30;

nothing happens with the captured preview.

Do I need to somehow notify one of these 2 components that there is change of the brightness value or what?

I know this is 3rdparty library, and I have contacted the creator, but haven't received any response.

Answer 1

Only thing that I missed was to set Enabled to true in Adjustment section of VLDSCapture ...
