Open source ambient lighting implementation with the audio visualization effects and video performance tweaks especially for USB grabbers. Support for HDR/BT2020 using LUT tables. Single and multi-threaded video processing optimization on Windows, macOS and Linux x64 & ARM (Raspberry Pi and others) for SDR/HDR streams captured by USB grabbers. Direct support USB grabbers for Windows 10 (Microsoft Media Foundation), Linux (v4l2) and macOS (AVFoundation). Also software screen grabbers are available now 🆕
Official releases:

Installers of the latest testing version (artifacts available in the latest build):
https://github.com/awawa-dev/HyperHDR/actions
Default LUT table is already included (in the installers) but you can generate your own or import 3dl Autodesk lut table.
For Raspberry Pi you may use prepared SD card images: manual
Default hostname for SD images is HyperHDR so connect to http://hyperhdr:8090/
SSH and SPI are enabled on default.

You don't need to use HDR source for usage of HyperHDR. You can just benefit from: significant higher performance for captured video stream from USB grabber over Hyperion NG, capability of using multithreading to avoid bottleneck resources, support for modern USB grabbers under Windows 10/Linux/macOS, decicated fast USB LED drivers (HyperSerialEsp8266 and HyperSerialWLED) or SPI driver (HyperSPI), screen grabbers including DirectX11 with HDR tone mapping, improved image to led colors averaging new algorihtms, music capabilities and few tweaks that minimize blinking at the dark scenes.
Use linux 'top' command with per core view (press 1) or preferable 'htop'. On Rpi 2/3/4 max limit is 400% (4 cores per 100%). The problem will occure when one of the core's usage is close to the 100% limit, not when overall usage is for example between 200-300% where each core if far from the individual limit.
Check the performance statistics that are updated every minute in System➔Log page.
Use YUV(YUY2) / XRGB(RGB32) encoding format if it's possible. It provides better quality and lower CPU usage.
We do not support driving WS281x or especially SK6812 LED strips directly from the Raspberry Pi. If you made it and it works, fine, but most of our users weren't so lucky. You should use external ESP8266/ESP32 (preferable with CH340G or CP2104 onboard) and voltage level shifter.
Usage of WS281x LED strip with Rpi directly (PWM mode) requires root privilages. Otherwise you may get 'Error message: mmap() failed' (read more)
It's possible to switch off/on HDR tone mapping remotely with home automation system. You can build commands for HyperHDR using out JSON API playground 🆕
Before and after HyperHDR LUT correction on HDR/BT2020 video that was broken by the USB grabber.
Without it your ambient lighting colors will be washed-out:
