Quick start examples for integrating Banuba SDK on Desktop in C++ apps

Getting Started

1. Get the latest Banuba SDK archive for MacOS/Windows and the client token. Please fill out our form at form at banuba.com website, or contact us via info@banuba.com.

2. Copy bnb_sdk.tar.gz/mac (for Mac OS) or bnb_sdk.zip/bin with bnb_sdk.zip/include (for Windows) into OEP-desktop/bnb_sdk dir.

3. Windows only: copy contents of bnb_sdk.zip/resources into OEP-desktop/resources.

4. Copy and Paste your client token into the appropriate section of [OEP-desktop/main.cpp][main.cpp#L15]

5. Copy effects from release archive into OEP-desktop/resources. Configure effect in the appropriate section of OEP-desktop/main.cpp, e.g. effects/test_BG The effects folder should be located in the OEP-desktop/resources folder. More effects can be found here

6. Generate project files by executing the following commands:

   Windows x86 build:

       cd %path_to_repository%
       git submodule update --init --recursive
       md build
       cd build
       cmake -A Win32 ..

   Windows x64 build:

       cd %path_to_repository%
       git submodule update --init --recursive
       md build
       cd build
       cmake -A x64 ..

   macOS build:

       cd %path_to_repository%
       git submodule update --init --recursive
       mkdir build
       cd build
       cmake -G Xcode ..

7. The previous step will generate a Xcode project for macOS and a Visual Studio project for Windows. Open the viewer_standalone project in an appropriate IDE on your platform.

8. Select target example in Xcode or set the example project as Startup in Visual Studio.

9. Run build.

Sample structure

• oep - is a submodule of the offscreen effect player
• libraries
  • glad - OpenGL loader
  • renderer - used only to demonstrate how to work with offscreen_effect_player. Draws received frames to the specified GLFW window
  • utils - wrapper for GLFW
• main.cpp - contains the main function implementation, demonstrating basic pipeline for frame processing to apply effect offscreen
• effect_player.cpp, effect_player.hpp - contains the custom implementation of the effect_player interface with using cpp api
• render_context.cpp, render_context.hpp - contains the custom implementation of the render_context interface with using GLFW
• camera_utils.cpp, camera_utils.hpp - contains a method that helps convert bnb::full_image_t type to OEP pixel_buffer type

How to change an effect

1. Open OEP-desktop/main.cpp

2. On line 45 find:

    oep->load_effect("effects/Afro");

3. Write the effect name that you want to run. For example: ("effects/your_effect_name")

Note: The effect must be in OEP-desktop/resources/effect.

Integration note

For the integration of the Offscreen Effect player into your application, it is necessary to copy the OEP folder and implement interfaces for effect_player and render_context, but if your application is based on the GLFW library and using bnb_effect_player CPP API, you can just reuse the current implementation.
