Free Edtion vs Commercial Edition

MediaPipe4U provides a suite of libraries and tools for you to quickly apply artificial intelligence (AI) and machine learning (ML) techniques in Unreal Engine project. You can plug these solutions into your UE project immediately, customize them to your needs. Include motion capture , facial expression capture for your 3D avatar, text to speech (TTS), speech recorgnization (ASR), etc. All features are real-time, offline, low latency and easy to use.

Latest update: 20240520

• [new] 🌈 Unreal Engine version 5.4 support, I skipped UE 5.3, I'm sorry for that.
• [new] 🌈 Control Rig supported (preview). Add a new animation blueprint node ControlRigFromPose that used to convert FK poses to Control Rig Blueprints pose.
• [new] 🔥 Upgrade to latest goole mediapipe holistic task api, got better performace for holistic tracking.
• [fix] #130: When packaging a game, the mediapipe model file is missing.
• [improve] Optimize android performace, now Android platfrom can reach 15-20 fps (CPU: Qualcomm Snapdragon 870 ).
• [remove] 🤢 LLM plugin has been removed. Because of the high latency of the LLM and the frequent updates of the llama.cpp project for a long time, there is no stable version. So I remove it, and maybe it will come back in the future.
• [remove] 🤢 Since this version, the 5.0.x version of UnrealEngine is no longer supported. Because 5.0.X requires VS 2019 and VS 2019 is no longer installed on my development PC. Sorry for that, but the older versions of the 5.0.x plugin are still available.

• Google's new holistic task API doesn't support GPUs, so Android uses CPU inference, and Windows, as always, CPU inference.
• Sine Unreal Engine 5.4 , the 'OpenCV' engine built-in plugin no longer contains precompiled libraries (dll files), the first time of the engine launched, because M4U dependent on the 'OpenCV' plugin, the UE Editor will try to download the OpenCV source code over the internet and compile it, this process may take a long time, it feels like the UE loading is stuck at 75%, please be patient and wait it, for Chinese users, you may also need a VPN networking for that, you can do this manually: #166.

Because the plugin is precompiled and contains a large number of C++ link symbols and debug symbols, it will cost 10G disk space after decompression (most files are UE-generated binaries in Intermediate).
Don't need to worry about disk usage, this is just disk usage during development, after the project is packaged, the plug-in disk usage is 300M only (most files are GStreamer dynamic library and speech models).

Now, M4U support Android and Windows (Linux is coming soom)

The license file will be published in the discussion, and the plugin package file will automatically include an license file.

Since the Windows version of MediaPipe does not support GPU inference, Windows relies on the CPU to inferring human pose estimation (see MediaPipe offical site for more details).

1. M4U used MediaPipe for motion capture and face capture.
2. M4U used NVIDIA Maxine AR SDK for facal capture.
3. M4U used Paddle Speech for TTS.
4. M4U used FunASR for ASR.
5. M4U used whisper.cpp for ASR.
6. M4U used GStreamer for video and live streaming decoding.
7. M4U used llama.cpp for inference of LLaMA2 model.
8. M4U borrowed a lot of code from PowerIK for ground ik.
9. M4U borrowed a lot of ideas from Kalidokit for mocap.
10. M4U borrowed a lot of code from wongfei for gstreamer/mediapipe integration.
