About

This plug-in is still under development and likely has a lot of remaining issues to be fixed. Use in production is not yet recommended.

Make sure to pull the Tag that matches your Unreal Engine version. If you sync to Master the code may not compile, because it may depend on Engine changes that are not yet available in the UE4 Master branch.

Supported Platforms

This plug-in was last built against Unreal Engine 4.19 and tested against the following platforms:

  • Linux (Ubuntu 18.04 LTS (Bionic Beaver))
  • Mac
  • Windows

IMPORTANT: Please note that this repository contains pre-compiled binaries for opencv_ffmpeg, which are licensed under LGPL. This means that you cannot create monolithic builds of your game without violating LGPL, the UE4 EULA or both. The opencv_ffmpeg libraries must remain dynamic libraries that are bound at run-time - static linking is not allowed - and the licensing related files must be retained.

This also means that this plug-in cannot work on platforms that do not support dynamically linked libraries (i.e. iOS, HTML5) or do not currently implement support for it.

Prerequisites

A relatively recent version of OpenCV 3 is required. The Ubuntu default stable release is not sufficient.

Linux (Ubuntu 18.04 LTS (Bionic Beaver))

A suitable version of OpenCV 3 must be installed or compiled from source. If you ship your game on Linux, you will likely want to include OpenCV 3 library with it, so that users don't have to install it themselves. I am including those binaries in this repository, although it is not clear what distros should be supported and where the builds are coming from.

Use clang as default C/C++ compiler for Ubuntu 18.04 LTS.

Mac, Windows

All required libraries and plug-ins are included in the Binaries directory and work out of the box.

Dependencies

This plug-in requires Visual Studio 2017 and either a C++ code project or the full Unreal Engine 4 source code from GitHub. If you are new to programming in UE4, please see the official Programming Guide!

Usage

You can use this plug-in as a project plug-in, or an Engine plug-in.

If you use it as a project plug-in, clone this repository into your project's /Plugins directory and compile your game in Visual Studio 2017. A C++ code project is required for this to work.

If you use it as an Engine plug-in, clone this repository into the /Engine/Plugins/Media directory and compile your game. Full Unreal Engine 4 source code from GitHub is required for this.
