QNapi Build Status Build status GitHub release Github All Releases

QNapi is free software for automatic fetching subtitles for given movie file. It uses online databases such as NapiProjekt, OpenSubtitles and Napisy24. It is based on Qt5 library, so it can be launched on any supported operating system, including Windows, OSX and Linux.

Binary packages

Latest binary packages are available at http://qnapi.github.io/#download

Building from source


  • C++ compiler with c++11 support installed (clang++, g++ or MinGW for Windows), present in PATH
  • Qt 5.2+ (most recent 5.x recommended) installed with qmake present in PATH (you can find one at http://www.qt.io/download-open-source/)

Binary prerequisites

QNapi requires these binary dependencies:

  • p7zip (7z, 7za) - to unpack subtitles, which are commonly compressed with 7zip
  • libmediainfo - to retrieve movie info such as dimensions, duration and frame rate

Linux/UNIX users can find these dependencies in separate packages.

Statically compiled p7zip binaries are provided in this repository for Windows/OSX users at win32/content/7za.exe and macx/content/7za, respectively. Similarly, compiled libmediainfo libraries are provided for Windows/OSX in deps/libmediainfo/.

WARNING! Precompiled binaries are stripped from the source archive!

Cloning the source code

First, you have to clone project source code using git client:

$ git clone --recursive https://github.com/QNapi/qnapi.git


To compile the application, you have to execute two following commands in qnapi root directory:

$ qmake

This will produce Makefile.

By appending CONFIG+=no_cli or CONFIG+=no_gui to qmake invocation you can disable building command-line or graphical interface binaries.

$ make (or mingw32-make on Windows)

This will compile the sources and build executable binary (or app bundle on OSX).

Important! Windows users have to execute one more command:

$ make install (or mingw32-make install)

This one will copy all binaries, libraries and other dependencies to win32/out directory.


By default, output binaries are placed by make in different locations, depending on your operating system:

  • Linux - qnapi in root project directory
  • OSX - macx/QNapi.app bundle
  • Windows - win32/out/qnapi.exe executable

After you locate your binaries, you can run the application.

7zip note

For proper subtitle extraction after download, 7zip executable is required to be passed in application's settings. Linux users have to install 7zip binary package from distribution repositories or compile on its own. For Windows and OSX there are pre-built binaries included in this repository, in win32 and macx directories appropriately and should be automatically detected by the application.

Making redistributable package



You need appdmg script installed. You can found it at https://github.com/LinusU/node-appdmg

Building .dmg image

To build .dmg image for OSX with nice, drag&drop installer, you have to execute:

$ make appdmg

QNapi-x.y.z.dmg will appear in macx directory when command is completed.



You need to have NSIS 2.x installed. You can found it at http://nsis.sourceforge.net

Also, you will need to manually install NSIS plugin nsProcess. It can be found at http://nsis.sourceforge.net/NsProcess_plugin

Building Windows installer

Installer script is placed at win32/QNapi-setup.nsi. You can build binary exe package using NSIS user interface (by right mouse button -> compile NSIS script) or from command line:

$ C:\Path\To\makensis.exe QNapi-setup.nsi

After a while, QNapi-x.y.z-setup.exe file will appear in win32 directory.
