Setup:
- Fresh flash of Hyberbian on a Raspberry Pi 3 Model B Rev 1.2 w/ a separate 2.1 Amp PSU
- Ezcoo splitter on a separate 2.1 Amp PSU, supports 4k 120 Hz input, EDID is set to 001 (TV mirror + DD 5.1), HDMI 2 is configured to downscale to 1080p - https://www.amazon.com/dp/B0CXXN58DJ?tag=hyperioforum-21
- Hagbis USB 3.0 1080p 60 Hz capture card, supports YUY2 and MJPEG - https://www.aliexpress.us/item/3256806324319513.html
- WS2812B LEDs, 96/meter, GRB byte order (service is running in root mode) - https://www.aliexpress.us/item/3256807982047486.html
- 15 Amp PSU for LEDs w/ voltage injection at the start and end - https://www.amazon.com/dp/B08764XJ2M?tag=hyperioforum-21
- Dual pi ground pins to LED strip ground, PCM on standard GPIO 18
In scenes that are black, like the start of a movie/show on Netflix, all the lights are white, maybe about 50% brightness.
Additionally black bar detection isn't working for either top/bottom WS movie formats or old 4:3 formats.
Any help would be appreciated.
Screenshots of current configuration:
edit: Fixed black bar detection by bumping Threshold up to 60%. 55% wasn't enough.
edit2: Turned Backlight threshold down to 0, lights are still white on black screens.
edit3: Everything is working now. All due to Hardware brightness control, I think. Seems pretty good now at 50. Was able to turn black bar detection down to 15 and black screens are now black.
