DirectShow questions - TheoRI - 01-31-2012 06:43 AM
I am trying to build an app using VideoLab for a home project. Do not have much experience with Delphi but hacking it along with the examples provided.
Need to be able to control the brightness and other options under
VLDSCapture1.adjustment
I use a scrol bar to adjust brighness and use the following code
procedure TForm1.BrightnessAdj(Sender: TObject);
begin
Bright_Var := BrightnessScBar.Position; {set the Brightness variable to the position of the brightness scroll bar }
VLDSCapture1.Adjustment.Brightness.value := Bright_Var ; {Set the brightness of the filter to the brightness variable }
BrightVal.Caption := inttostr(Bright_Var); {Show the value of the brightness variable in a label box}
end;
Can you please help in telling me how do go about doing this.
Anyone has a substantial application that they would be willing to share so I learn.
Can I set the exposure for the camera I am using?! I figure its under the TVLDSCameraControlProperty...
I still have to figure out the user interface for saving a file,

For Apple perhaps...
Anywho, if you have VLDSCapture1.Enabled set to true and Brightness.Mode set to amManual your code should work, that is.. if your cam/driver etc. supports it, same for exposure.
Regards,
Dave

I want to create video files. I need to know which software to use and how to implement VLDCapture1 for that...
