Good afternoon, help a noob please. I have been interested in the Ambilight system with Hyperion and as I have a 4k tv and I love its operating system, I am trying to use a camera in front of the tv to capture the image. I'm using the following intens: - Raspberry pi 3+ - Arduino uno atmega328p - Led strip WS2812B - Font 5v 10a supply for the ribbon - Font 5v 2a source for rpi On the raspberry I used the hyperion.ng installed by the raspbian taken from this video: In Arduino I used "Adafruit_NeoPixel" configured for 272 leds, 87 horizontal and 49 vertical Well, my doubt is this: I saw in this thread https://hyperion-project.org/threads/hyperion-source-from-cam-in-front-of-tv-prepare-input-region.2615/#post-10103 that some people used a Camera Pi, ps3 eye or a normal usb camera to capture the image from the tv. I tried all the ways and I couldn't get the rpi to receive the image from my cameras! I have to use a grabber (v42l) or some other device to receive this video. I am new to this type of programming, but I have read a lot about it. Anyone who can help me, I really appreciate it!
