||
|
||
## Requirements:
|
||
* Visual C++ Redistributable for Visual Studio 2015<br>
|
||
Files: msvcp140.dll, msvcp140d.dll in "Delphi-OpenCV\redist\" or [here, but it is not exactly][2]<br>
|
||
or from the repository (Delphi-OpenCV\redist\VC14):
|
||
```
|
||
(1) 32-bit in the "\x86"
|
||

|
||
```
|
||
* Shared library FFMPEG 4.2.1 for Windows can be downloaded from [here][5]<br>

|
||
```
|
||
(3) FFmpeg 32-bit Shared "\x86"
|
||
(4) FFmpeg 64-bit Shared "\x64"
|
||
```
|
||
* Dynamic library OpenCV need to download [here][4]<br>
|
||
Files: *2413.dll and *2413d.dll<br>
|
||
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][3]<br>
|
||
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][1] or clone repository<br>
|
||
```
|
||
git clone https://github.com/Laex/Delphi-OpenCV.git
|
||
```
|
||
Get the following directory structure<br>
|
||
```
|
||
<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 <b>InitDelphiFFMPEG.cmd</b> to initialize the <b>Delphi-FFMPEG</b> submodule. The <b><Delphi-FFMPEG></b> directory should be populated with sources for <b>Delphi-FFMPEG</b>.
|
||
If it didn<64>t work, then
|
||
```
|
||
git clone https://github.com/Laex/Delphi-FFMPEG.git
|
||
```
|
||
Add the search path for the modules of the project in Delphi IDE<br>
|
||
"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.<br>
|
||
## 2. Copy dynamic libraries files
|
||
<b>OS Windows 64-bit</b><br>
|
||
```
|
||
Target platform 64-bit: (2),(4),(6),(8) -> "C:\Windows\System32\"
|
||
Target platform 32-bit: (1),(3),(5),(7) -> "C:\Windows\SysWOW64\"
|
||
```
|
||
<b>OS Windows 32-bit</b><br>
|
||
```
|
||
Target platform 32-bit: (1),(3),(5),(7) -> "C:\Windows\System32\"
|
||
```
|
||
<b>Alternatively</b>, 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:<br>
|
||
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\VCLDemo\VCLDemo.groupproj
|
||
```
|
||
Examples of using FFMPEG library header files are in the
|
||
```

||
<PROJECT_ROOT>\Delphi-FFMPEG\examples
|
||
```
|
||
Examples of use of components
