This is a step by step tutorial for writing a simple video processing application in Delphi or C++ Builder VCL by using VideoLab.
The steps are exactly identical in Delphi or C++ Builder versions 5 to 2007.
There is no code writing necessary to complete this application.
There is no need to know Delphi or C++ Builder in order to create this application.
The steps bellow are captured using Delphi 2007, however they are identical in C++ Builder and older versions of the products.
The tutorial covers the following steps, which should take less than two minutes:
