You dont need to compile avidemux yourself to write your own plugins.
What you need is :
It is a good idea to use a short path, i.e. c:\MingW64 and c:\msys64 Make sure you have them both in your path (i.e. c:\Mingw64\mingw64\bin and c:\msys64\usr\bin)
You will need to install cmake version 3.x
Make sure the cmake “bin” folder is in your path
It is best to start here to make sure you have a working environment
Start a MSYS2 shell, go where you unzipped the demo code (i.e. c:\tmp\videoFilterDemo for example )
Create a build folder
mkdir build && cd build
then generate the makefile
cmake -G "MSYS Makefiles" -DCMAKE_MAKE_PROGRAM=mingw32-make -DCMAKE_INSTALL_PREFIX="c:\Program Files\Avidemux 2.6 - 64 bits" ..
The CMAKE_INSTALL_PREFIX should point to the place where avidemux is
Look for error, it should go without problem.
Upon success, copy the dll in c:\Program Files\Avidemux 2.6 - 64 bits\plugins\videoFilters\
Start avidemux and you should see a logo_sample filter in the menu list
If the C++ library used by mingw is more recent than the one used by avidemux itself you'll run into two problem :
Do the fixes above, erase the build folder (build/*) and do it all over again (it takes 5 sec)
You'll need the same requirement as above (i.e. cmake, msys,…)
You *MUST* add msys make, mingw make will not work with netbeans
Open a msys2 shell, and enter
pacman -S make
There are two parts :
Everything is coming from msys, the screenshot is a bit old
The important part are :
-G “MSYS Makefiles” -DCMAKE_INSTALL_PREFIX=“c:/Program Files/Avidemux 2.6 - 64 bits”“
Note that the path separator are ”/“ and not “\”!
You can build the sample now.
In case you made a mistake, dont forget to delete the CMakeCache.txt file before retrying
