Requirements:
- Visual C++ Redistributable for Visual Studio 2015
Files: msvcp140.dll, msvcp140d.dll in \”Delphi-OpenCV\\redist\” or here, but it is not exactly
or from the repository (Delphi-OpenCV\\redist\\VC14):
(1) 32-bit in the \"\\x86\"
(2) 64-bit in the \"\\x64\"
- Shared library FFMPEG 4.2.1 for Windows can be downloaded from here
or from the repository (Delphi-OpenCV\\redist\\ffmpeg):
(3) FFmpeg 32-bit Shared \"\\x86\"
(4) FFmpeg 64-bit Shared \"\\x64\"
- Dynamic library OpenCV need to download here
Files: *2413.dll and *2413d.dll
After installing OpenCV:
(5) 32-bit in the C:\\OpenCV\\build\\x86\\vc14\\bin\\*.dll
(6) 64-bit in the C:\\OpenCV\\build\\x64\\vc14\\bin\\*.dll
- Some examples (FFMPEG) required SDL 2.0 and SDL 1.2
or from the repository (Delphi-OpenCV\\redist\\SDL\\1.2 and \\2.0):
(7) 32-bit - SDL.dll and SDL2.dll \"\\x86\"
(8) 64-bit - SDL.dll and SDL2.dll \"\\x64\"
How to install:
1. Delphi environment setting
Download and unzip the archive or clone repository
git clone https://g*ithub**.com/Laex/Delphi-OpenCV.git
Get the following directory structure
<PROJECT_ROOT> - Directory, for example, \"C:\\Delphi\\OpenCV\\\"
<bin> - here are the executable files of the examples
<CheckCVDep> - program for checking the environment
<Delphi-FFMPEG> - empty directory for \"Delphi-FFMPEG\"
<packages> - packages for D10-D10.3
<redist> - redistributable packages
<resource> - media for working examples and Haar-cascades
<samples> - examples
<source> - object pascal sources for OpenCV, SDL, OpenGL
<source3> - attempt for opencv 3
<source4> - blank for OpenCV 4
Run InitDelphiFFMPEG.cmd to initialize the Delphi-FFMPEG submodule. The directory should be populated with sources for Delphi-FFMPEG.
If it didn’t work, then
git clone https://*g*ith*ub.com/Laex/Delphi-FFMPEG.git
Add the search path for the modules of the project in Delphi IDE
\”Tools-Options-Delphi Options-Library-Library path\” or \”Tools-Options-Language-Delphi-Library\”
<PROJECT_ROOT>\\source
<PROJECT_ROOT>\\source\\opengl
<PROJECT_ROOT>\\source\\sdl
<PROJECT_ROOT>\\source\\sdl2
<PROJECT_ROOT>\\packages
<PROJECT_ROOT>\\resource
<PROJECT_ROOT>\\resource\\facedetectxml
<PROJECT_ROOT>\\source3
<PROJECT_ROOT>\\Delphi-FFMPEG\\source
where <PROJECT_ROOT> directory, which was unzipped (or cloned) repository.
2. Copy dynamic libraries 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\\\"
Alternatively, dynamic libraries can be placed next to an executable file.
3. 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
4. Install the components
To install the components, open and install
<PROJECT_ROOT>\\packages\\Delphi XXX\\rtpFFMPEG.dpk
<PROJECT_ROOT>\\packages\\Delphi XXX\\rclVCLOpenCV.dpk
<PROJECT_ROOT>\\packages\\Delphi XXX\\rclFMXOpenCV.dpk
<PROJECT_ROOT>\\packages\\Delphi XXX\\dclVCLOpenCV.dpk
<PROJECT_ROOT>\\packages\\Delphi XXX\\dclFMXOpenCV.dpk
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>\\Delphi-FFMPEG\\examples
Examples of use of components
<PROJECT_ROOT>\\samples\\Components\\ComponentsDemo.groupproj
