Copy files

OS Windows 64-bit

Target platform 64-bit: (2),(4),(6),(8) -> "C:\Windows\System32\"
Target platform 32-bit: (1),(3),(5),(7) -> "C:\Windows\SysWOW64\"

OS Windows 32-bit

Target platform 32-bit: (1),(3),(5),(7) -> "C:\Windows\System32\"

How to install:

Download the archive.
Unzip it to a convenient directory, thus get the following directory structure

<PROJECT_ROOT> - Directory, for example, "C:\Delphi\OpenCV\"
    <bin>
    <redist>
    <resource>
    <samples>
    <source>

Download the FFmpeg Delphi/Pascal Headers and extract to \source\ffmpeg
Add the search path for the modules of the project in Delphi IDE (Tools-Options-Delphi Options-Library-Library path)

<PROJECT_ROOT>\source
<PROJECT_ROOT>\source\classes
<PROJECT_ROOT>\source\component
<PROJECT_ROOT>\source\ffmpeg\headers
<PROJECT_ROOT>\source\opengl
<PROJECT_ROOT>\source\sdl
<PROJECT_ROOT>\source\sdl2
<PROJECT_ROOT>\source\utils
<PROJECT_ROOT>\resource\facedetectxml

where <PROJECT_ROOT> directory, which was unzipped project.

To install the components, open and install

<PROJECT_ROOT>\source\component\DelphiXX\dclCommonOpenCVXXX.dpk
<PROJECT_ROOT>\source\component\DelphiXX\dclFFMSourceXXX.dpk
<PROJECT_ROOT>\source\component\DelphiXX\dclFMXOpenCVXXX.dpk
<PROJECT_ROOT>\source\component\DelphiXX\dclVCLOpenCVXXX.dpk

Verify that the environment is configured correctly

Run from the repository

 Delphi-OpenCV/CheckCVDep/CheckCVDep.exe

The program checks the availability of dynamic libraries

------- Verifying Microsoft DLL -------
OK
------- OpenCV DLL -------
OK
------- Delphi-OpenCV classes DLL -------
OK
------- FFMPEG DLL -------
OK
------- SDL DLL -------
OK

To successfully install components and run most of the examples, the availability of FFMPEG DLL, Microsoft DLL and OpenCV DLL is sufficient

Examples

Open in Delphi IDE and compile:
Examples of the use of certain functions and procedures

<PROJECT_ROOT>\samples\LibDemo\LibDemo.groupproj

Examples of the use of video processing algorithms

<PROJECT_ROOT>\samples\MultiDemo\MultiDemo.groupproj

Examples of the use of video processing algorithms using VCL.Forms

<PROJECT_ROOT>\samples\VCLDemo\VCLDemo.groupproj

Examples of using FFMPEG library header files are in the

<PROJECT_ROOT>\source\ffmpeg\examples

Examples of use of components

<PROJECT_ROOT>\samples\Components\ComponentsDemo.groupproj
