Build

• Java 21 required

Building Windows

1. If you don't have git configured to create symlinks, you have to delete the windows\native\LibRender\LibRender\src file and instead create a symlink. You can do this by opening a Command Prompt with admin permissions and running:

   cd windows\native\LibRender\LibRender
   del src
   mklink /d src ..\..\..\..\core\native
   

2. First, generate the lib render JNI headers: (You may use the Generate Headers IntelliJ Run Config)

   mvn compile -pl core
   

3. Open windows\native\LibRender\LibRender.sln on Visual Studio

4. On Visual Studio, compile LibRender dynamic library

5. Package the Windows jar (You may run the Package Windows IntelliJ Run Config)

   mvn clean package -pl core,windows
   

   The Windows jar should be created at windows/target/projector-windows-x.x-jar-with-dependencies.jar

Building Linux

Be sure to have gcc installed and also the opengl library development headers

Just run (Or, use the Package Linux IntelliJ Run Config)

mvn clean package -pl core,linux

Building OSX

1. Install VLC Player App

2. Install GLFW via Brew

   brew install glfw
   

3. Generate the lib render JNI headers: (You may use the Generate Headers IntelliJ Run Config)

   mvn compile -pl core
   

4. Open the XCode project and compile the libProjector

5. Package the OSx jar (You may run the Package MacOs IntelliJ Run Config)

   mvn clean package -pl core,osx
   

   The OSx jar should be created at osx/target/projector-osx-x.x-jar-with-dependencies.jar

Note: The OSx project is not done yet. There are missing platform dependent features: Video Device capture and Window capture

Minimum Requirements

To execute projector software you will need:

• GPU with OpenGL 3.2 and GLSL 1.0 support (you can even use mesa, however performance may be degraded)
• 2GB free ram for running the software

Windows

No special requirements

Linux

• This software only works with X11.

Install

Windows

1. Install Java 21
2. Install Microsoft Visual C++ Redistributable
3. Install VLC Player (version 3.x)

   Beware

   • You must install VLC 64 bits. Pay attention that VLC website by default directs to the 32 bits version. Be sure to select the 64 bits distribution.
   • Install VLC Player on the default location. Other locations won't work with this software

Linux

1. Install Java 21
2. Install Vlc Player from Ubuntu Software, or from your package manager

Window Configurations

The default window config will create a projection window at the first non-primary monitor.

This can be changed, and there's also a wonderful world of possibilities:

• Support for blending projectors (Blending, advanced color matching, black level adjust)
• Support for live broadcast lyrics output (with green background)
• Support for stage monitors
• Full automatic and output independent lyrics line breaking (it can break lines for main output while keeping non-broken lines for live broadcast output)
• Splitting screen support (you may use a 2x2 HDMI Wall Controller and split 1 video output into 4 independent outputs)
