The recent availability of affordable HDMI splitters and capture devices make it much more practical and this implementation looks really well done.

Getting a working Ambilight clone using only the HDMI input signal has been a project I’ve had on the back burner for over a decade. This one just does one thing, but thanks for the info!

Hyperion looks awesome, but it also lets you do a ton of different things like control Hue lights/USB/has a full app etc. These I worked on a bit to try get it down but actually its just the time it takes to PWM the signal across the GPIO18 pin, so if you have less than 500 LEDs (what mine is set to now) then you should get way more FPS.ĭue to an issue where I cannot re-assign LED length without re-instantiating the LED library it means that to configure it I need to estimate 500-ish LEDs, but if I knew the length I could definitely push way about 40FPS.Īdditionally while the openCV stuff is cool, a lot of the setup and pain comes from the HDCP/EDID/HDMI config where you still want to get 4K with HDR, but really this is all handled by the easycoolav splitter. I watched some of the videos and went through the docs and arguably this could definitely be done with Hyperion, all they would need to support is something like the adafruit circuitpython neopixel library and you could connect them with Hyperion.įPS is a little difficult to really judge because likely your FPS you are referring to the capture rate and not the LED updates per second. Honestly, I just hadn’t seen the project before. Posted in Raspberry Pi Tagged ambilight, hdcp, hdmi, raspberry pi, television Post navigation

We’ve seen plenty of hacks in this vein before one of the most impressive hacked a smart TV into doing the video processing itself. The Fourth Wave still eludes us, but we hold out hope. As an added bonus, he also gave the system an audio visualiser, and tested it out with some Streetlight Manifesto, the greatest third-wave ska band ever to roam the Earth.

You can build one too, since shared all the code on Github.

With 270 LEDs fitted, the result is an incredibly smooth and fluid ambient display we’d love to have at home. It even autoscales to work with video content shot in different aspect ratios so the ambient display always picks up the edge of the video content. From there, it was simple enough to send out data to a string of addressable RGB LEDs behind the TV to create the desired effect.įor all the hard work, was rewarded with an ambient lighting system that runs at a healthy 20fps and works with any HDMI video feed plugged into the TV. After solving annoying problems with HDCP and HDMI splitters, he was finally able to get a Raspberry Pi to capture video going to his TV and use OpenCV to determine the colors of segments around the screen.

The development process was one full of roadblocks and dead ends, but persevered. Armed with the tools of the hacker trade, he set about building an Ambilight-type system of his own that truly delivered the goods. Had seen all kinds of ambient lighting systems for TVs come and go over the years, and the one thing they all had in common was that they didn’t live up to his high standards.
