My setup is different, I have everything plugged in a Yamaha receiver, including my LibreElec Pi4, and yes I have a dedicated Pi for hyperion.

I am asking you because we have the same converter and grabber. I will try some changes
Yeah same kind of model, but probably not exactly the dame...and LEDs are different too, so they can't be tuned exactly the same. -
Dude I can't do it for you...
Try to change values and see what happens.
Make a screenshot before starting so you can revert back if you're not satisfied. -
Have a look at the Configuration/Image processing tab
-
Of course, every setup has to be fine tuned.
Not all hardware are identical. -
Yeah I see, that is not flickering then.
You have to adjust colors and set some values for the thresholds. -
Flickering is a power problem.
How do you control the LEDs ? Directly from the Pi ?
If so did you add a resistor on the data line ? The Pi share the same ground as the LEDs ? -
If you can use a projector with that HDMI output then the screen sharing option is enabled.
You might wanna try and set Video standard to automatic and resolution to something smaller, like 720*480 for example.
I suspect that your Pi is not powerful enough to display the preview at such a high resolution (1920*1080).
I had that capture card too and even with a Pi3 live preview was buggy.
I'm sorry but I can't help you further on this.
Maybe someone else who reads this ? -
Did you enable screen sharing in your laptop settings ?

My current setup is wonderful and simple (Hyperion on RPi zero + usb hdmi capture + WS2812B).
The issue is when the HDMI source turns off, the LED lights revert to an unexpected color combination. I am assuming these are coming from the actual LED strip and not Hyperion. Look like Hyperion looses control of the LEDs when the signal is lost.
Is there a way in Hyperion to turn off the LEDs when the USB capture signal is lost? or even a specific effect.
Does it display some kind of rainbow ?
If that is the case, it is your grabber that sends this picture when it receives no signal.
In this case, you have to play with signal detection in the USB capture settings of Hyperion.NG
Search on the forum for signal detection, me and some other people already have explained how to deal with it. -
i only heard that the wifi-code part has issues...don't know which line or anything...but only with esp32..i also had those "flashes" in a previous version when i changed the brightness but not anymore....so definitely a software problem...
i have some china d1 minis...works great....
I've tried with an ESP8266 (china clone) and it was even worse lol
Well I guess I'll wait for the D1 mini to arrive and see what happens. -
Oh well that's related to something you already answered I believe.
I just wanted confirmation that it was not something faulty in my setup.
I have an ESP32 running the latest Wled, with 176leds WS2812b.
The ESP is at 1m from my router, but I regularly get some white flashes on leds (sometimes all leds, sometimes just a part of the strip).
It does the same if I use only WLed (meaning without hyperion), I get some flashes of random color.
I'm confident in my power brick (it's a stabilized one, 20A) and it delivers exactly 5V (measured with my Metrix).
I also have a 470Ohm resistor on my data line.
I have no problem with the same power brick and data line if I use an arduino to drive the same leds.
So I believe the problem sits somewhere in Wled or wifi.Do you think I can do anything for this or do I have to live with it ?
What can I check ?
(I'm not totally sure about the ESP32 though, thta's why I have ordered a genuine Wemos D1 mini, waiting for it). -
Kann ich eine Frage auf Englisch stellen?
Dies ist der einzige Ort im Forum, an dem es anscheinend Wled-Experten gibt. Leider spreche ich kein Deutsch (danke Google Übersetzer). -
-
Nope.
I got it a long time ago on Amazon and it's not available anymore.
It's a UTV007, not UTVF007, but that should not change anything for you. -
Maybe it is your HDMI2AV converter which is not at ease with downscaling from 4k to composite.
This is what I use :
https://fr.aliexpress.com/item…042311.0.0.27426c37m408iV (HDMI 1x2)
https://fr.aliexpress.com/item…042311.0.0.27426c37m408iV -
2.5w means it draws 0.5A from the brick.
The Pi itself draws at least 2A.
So you have approximately 5A remaining for your LEDs, allowing you to use properly between 90 and 100 LEDs.
If you have more than 100 LEDs in your setup, yes that 8A power brick is too weak.Consider 0,06A per LED, and 3A for the pi and the capture card. This way you Can determine what power brick you need.

Before changing the grabber, which in m'y opinion is perfectly fine, you should try and play with the settings of hyperion.NG...
What is the problem with your LEDs ? -
Set latch Time to 0, at the same place you set the baud rate (115200 is ok). You might need to enable advanced settings to see it. You Can Do this by clicking on the upper right icon in the WebUI.
Also, set Time to 100ms and update frequency to 50hz in the smoothing configuration (that is in the image processing tab of the webUI) -
Yeah I noticed this.
My splitter downscale 1 output so I get 2160 for the tv, and 1080 for the HDMI2AVYou have to consider that kodi and Hyperion are totally independent.
They run on the same hardware but they are separated.
