![]() ![]() The consumer should display the text "Awaiting control block from producer process.". ![]() Run the executable for an example consumer (e.g rawdump_consumer.cpp) with the command-line argument "UE4Capture", which will set the correct prefix value.Grab the MediaIPC source code and build the CMake project, including the example producers and consumers.First, create a MediaIPC consumer to receive the capture output: Getting started with UE4Capture plugin is extremely simple. Audio capture only works when using an output device based on the AudioMixer module, which requires running the game with the -AudioMixer command-line argument.The Conan package for libMediaIPC needs to be compiled by running the command build.py MediaIPC-ue4 from the ue4-conan-recipes repository.This issue is fixed in Unreal Engine 4.20. To fix this, run the script patch-headers.py in the scripts directory. Under Unreal Engine 4.19, one of the public header files for the UE4 AudioMixer module includes a private header file, causing compilation errors when included by non-Engine modules.For details on creating and using MediaIPC consumers, see the documentation from the MediaIPC GitHub repository. The plugin acts as a MediaIPC producer process, transmitting data to any running MediaIPC consumer process that has been initialised with the prefix "UE4Capture". This overcomes the lack of audio support when exporting movies using Sequencer, and also facilitates capturing audio and video when performing offscreen rendering on a headless device or inside an NVIDIA Docker container under Linux. This plugin utilises the MovieSceneCapture and AudioMixer modules to capture both audio and video from Unreal Engine 4 projects, without the need for external screen capture tools. We recommend that all developers upgrade to Unreal Engine 4.27 or newer and use the official Pixel Streaming plugin instead, which is maintained and supported by Epic Games. This project is no longer maintained or supported. In-Engine Audio and Video Capture Plugin for Unreal Engine 4 ![]()
