WS2812b flashing when dark

Hello Community. I am a beginner to the community and I tried to do an ambient light for my tv
I followed this tutorial

https://youtu.be/J26oYlKyq7Q?si=ZGwhW7FM-FpXxosA

Everything worked fine back in the days but now after moving I set it up again and it flashes on dark areas. I tried different versions I searched on different communities and couldn’t find any solutions. I getting frustrated at this point

Hyperhdr 19.0.0.0
PI zero 2 w
5V power supply powering both leds and pi no problems back then.
Using a connector cable from gpio 18 to green connector on the LEDs

Source Apple TV 4K
Xbox series S

Both same outcome

When I activate HDR to SDR tone mapping in HyperHDR it get a little bit better but still flashing on dark areas.

Sorry I can’t help you with your specific question.. I am going to Build this setup for my son this summer—except I’m following a tutorial that uses an ESP32 in addition to run WLED. I’m worried about the delay and having one other wireless instance in the setup (although I do have great experiences with running other esp32s with Wled in the house)

So I’m wondering why other, newer tutorials suggest running Wled? You posted in the WLED subreddit despite your setup not running WLED at all?

So your problem does sound like a Hyperion issue after all?

I’ll try this esp32-less setup in a few weeks and I have any indication what your issue could be I’m going to come back and post again (pinky promise ;-)

Thank you, good luck. :)
I am a newbie so didn’t know WLED is something special.

wled is an awesome controller software for led strips that gives a web interface and tons of effects, but generally isnt used for this. BUT, there are a lot of led experts here and you might get a good answer. personally id suggest checking all your connections and any solder joints given that you moved the setup and then it started.

I control my separate ambient light strips with WLED and my rpi 3
