Writing your own plugins, CLI and Netbeans Setup (Windows)

You dont need to compile avidemux yourself to write your own plugins.
What you need is :

  • Avidemux installed on your system
  • SDK component activated
  • CMake > 3.x and mingw64-32 or 64 installed CMake
  • Msys2 installed MSYS
  • Mingw64 installed MinGW64
  • A demo/sample video filter, available here

Make sure you have selected the SDK component during install

Msys2 and Mingw64 setup

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

Cli : Compile the sample using MSYS2/MinGW

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

Important/Common problem

If the C++ library used by mingw is more recent than the one used by avidemux itself you'll run into two problem :

  • If you have error undefined symbol _imp_xxxxstdcxx11xxxxbasic_stringxxx when compiling , add one line at the very top of CMakeLists.txt


  • If you have error at startup “Cannot locate xyz in libsdtc+++”, Overwrite the libstdc++-6.dll in the avidemux folder with the one from mingw, e.g. c:\Mingw64\mingw64\bin\libstdc++-6.dll

Do the fixes above, erase the build folder (build/*) and do it all over again (it takes 5 sec)

Using Netbeans


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  
Configure Netbeans

There are two parts :

  • Configure the toolchain
  • Configure the project

The toolchain should be configured as follow :
The important part is to select the make from msys64/usr/bin

Everything is coming from msys, the screenshot is a bit old

Last step is to setup the project :
Step 1
Step 2

Go to the project properties and :

  • Set the generator to MSYS
  • add CMAKE_INSTALL_PREFIX to avidemux folder (i.e. -DCMAKE_INSTALL_PREFIX=“c:/Program Files/Avidemux 2.6 - 64 bits”)

You can build the sample now.
