Color issues with usb capture devices

Nicholas Vasquez · 4. Februar 2021

Hi!!

I finally got everything all set up, and everything connected. I have a RPi 4, and an esp8266 device running WLED and WS2812b leds.
I have used 2 different usb capture devices and I have noticed that the live view that Hyperion is seeing have strange color issues. Like blue looking green, and red looking blue.

This contributes to the led output being wrong. Only once did I manage to get a good color palette from one of the devices.

Does anyone know how to fix this? Or what is causing the issue?

Any help is appreciated..

At menu ledhardware you switch the RGB to GRB /BGR or to different to switch the colours

If the image rendered to Hyperion.ng is wrong then you can test this with Mplayer.

Install in terminal on raspi and run, then you can see if the video is good or not. So... does it have anything to do with Hyperion.ng or is signal/grabber faulty?
You can find commands for the Mplayer in my comments.

First what I would do is updating libraries.

Sudo apt-get update
Sudo apt-get upgrade
Install libcec4 library

Install: cannot stat “libcec4” : no such file or library

I am a cli newbie. I don’t know what I’m doing wrong

The libcec4 line wasn't there to copy and use, only example.

You have to download the libcec4 and then install it for Hyperion.ng 2.09 alpha

Somewhere in my posts you can find the installation lines they are

sudo apt-get -d install libcec4
sudo apt-get install libcec4

Quick update. I havent forgotten about this. I’m just having trouble figuring out how to get some files onto a headless pi, and playing them. As I said I’m super new to cli, and YouTube-dl isn’t downloading anything. I tried installing kodi, but Hyperion isn’t picking up data to output.

edit: when I tried to install libcec4, it said the current version is already installed.

Jetzt mitmachen!
