Nlive Video Editor

Nlive is a free, open-source video editor for Windows, macOS and Linux.

Nlive is succeed to Olive, which is also a non-linear video editor, based on Electron. On the other hand, Nlive is built on Qt5.

Build Instructions

1. Get all the prerequisites described below

• CMake
  • Nlive uses CMake for meta build system.
• Qt5
  • Nlive is based on Qt5
• Boost
  • with Boost_USE_STATIC_LIBS=ON
• OpenGL
  • Nlive uses OpenGL for rendering
• FFmpeg >= 3.4
  • Nlive uses FFmpeg for decoding. Make sure the version is higher or equal than 3.4
• spdlog
  • Nlive uses spdlog for logging

2. Make sure CMake can find packages Qt5, Boost, OpenGL, FFmpeg, spdlog. The easist way is setting CMAKE_PREFIX_PATH environment variable as include paths and library paths of those. You need to add 4 paths which are

• QT5_BASE_PATH/QT5_VERSION/QT5_COMPILER/lib/cmake/Qt5
• FFMPEG_BASE_PATH/lib
• FFMPEG_BASE_PATH/include
• SPDLOG_BASE_PATH/include

And one last additional environment variable to find Boost

As for me, on Windows 10 with MSVC 2017,

%CMAKE_PREFIX_PATH% = Q:\Qt\5.13.0\msvc2017_64\lib\cmake\Qt5;D:\cpplib\ffmpeg-3.4\lib;D:\cpplib\ffmpeg-3.4\include;D:\cpplib\spdlog\include;

%BOOST_ROOT% = D:\cpplib\boost_1_70_0; %BOOST_INCLUDEDIR% = D:\cpplib\boost_1_70_0\boost; %BOOST_LIBRARYDIR% = D:\cpplib\boost_1_70_0\lib64-msvc-14.1;

3. Get sources from git

   git clone https://github.com/orange4glace/nlive.git

4. Create build folder

   cd nlive

   mkdir build

   cd build

5. Build the source with any way you want. We recommend you to use Ninja.

   cmake -G Ninja ..

   ninja

6. Copy and paste necessary dynanmic libs. (*.dll or *.a)

7. Run your program.
