Would I need an ESP32 with Raspi 4 for SK6812?

First time attempting to work with Hyperion/Hyper HDR. Based on everything that I've read, this is my plan.

I have an HDMI splitter input from my AVR to the splitter one to a video capture card one to the TV.

I have already Rasberry Pi 4 that I've loaded Rasberry OS lite on to run headless, I'm reading some of mentioning GPIO 18 on the Raspi as the data to the LED while other mentioning of an ESP32.

I'm familiar with WLED and have lots of them running through out the house. If I went with ESP32 WLED route, then it would be WLED to the TV as any other WLED and then wireless communicate from Hyperion or HyperHDR to IT?

I much rather have the LED physically control by the Raspberry Pi if possible as I feel there is stability issues with anything wireless.

Seems SK6812 is going to give me best result so that's my plan for LED.

The SK6812 can be connected directly to the Raspberry Pi.

Controller type: SK6812spi

GPIO 10 - SPI Mosi

SPI must be enabled on RPI.

The ESP32 with WLED offers many additional options. There's also an ESP with an Ethernet port if you're concerned about problems or latency when using Wi-Fi.

Compatible controllers - WLED Project

P.S. This is the Hyperion forum; you're in the wrong place for HyperHDR.
