How to build an Ambilight for every HDMI input source using a Raspberry Pi @Raspberry_Pi #piday #raspberrypi
Check out this tutorial from Christian Moser at TechTalk on how to build an ambilight for every HDMI input source with help from a Raspberry Pi.
In this post I’m going to show how you can configure your Hyperion Ambilight for every HDMI source. If you don’t have an Hyperion setup, I kindly refer you to my previous Ambilight guide.
We need to get the color information from an HDMI input signal. For this purpose, it’s necessary to transform the digital HDMI signal to an analog composite one with a converter. After this, we can grab the composite signal with an USB video grabber connected to the Raspberry Pi. Now we’re able to feed Hyperion with the color information by the video grabber.
