It seems that micro usb cable use to power on RPi has an issue. It seems that it is not able to provide quality power supply to RPi.

I have connected micro USB cable to output pins of SMPS (used in desktop systems). This mechanism seems is not best approach.

I can see two approaches:

1. Use power adaptor comes with RPi - It has 230V AC input and 5V DC output (micro USB). Can I connect RPi power adaptor input (230V) and SMPS power supply input to same powerpoint so that ground connection remains same?

2. Use 5v (pin#1) and GND(pin#3) pins on RPi board to SMPS 5v ouput ports. Is it safe to connect this way?

Any other recommended approach ?

Unfortunately, problem starts occurring.

when you power on RPi, it does not recognize video capture card . But if you change resolution setting or deactivate and activate capture card then capture card starts functioning.

But after some time again RPi does not find grabber.

I have tried everything, change HDMI cable & video capture card and reinstall of hyperbian. But no luck.

RPi is powered up by SMPS (used in desktop). Its voltage is 5.23V.

Now last thing to change is RPi itself

I did reinstall hyperbian on SD card. Now it is working fine.

Hope it continues to work same. Will monitor.

Just FYI: I tried with Hyperion on Raspberry Pi OS. But somehow Hyperion was not able to control LED (2812). I followed steps as mentioned "https://docs.hyperion-project.org/en/user/Installation.html#raspberry-pi".

Then I tried with Hyperbian. It is working now.

Maybe instructions related with "root user" requirement are missing in the first approach (not mentioned on URL site).

Unfortunately it did not work.

Let me format and reinstall Hyperion on RPi.

I checked grabber on my PC. It works fine.

It does not work with RPi. Can we install driver for same?

RPi detects USB video device i.e grabber as per below info:

Hi,

I changed HDMI cable and also added max_usb_current=1 command in config.txt. But still no change.

I observed that if device resolution or frames value changes then again LED works but for only min. Again back to Idle state.

Is it it due to normal Video capture card? Should I changed it to 4K one?

Or reinstall hyperion program on RPi?

Hi,

I have setup ambient light project on Raspberry Pi 3 model B with Hyperbian image. Hyperion version is 2.0.13.

I have 4K HDMI splitter from Orei (UHDS-102) and normal HDMI Video capture USB card, specifications as shown below:

Below is my USB capture settings:

Issue: WS2812 LED and Philips HUe LED work fine for few minutes and goes back to idle state due to absence of video image.

Below are logs:
