hyperion.ng VS piccap

You can DIY your own with a IC-based RGB/RGBW strip and a rPi or x86 PC + ESP microcontroller using software like Hyperion or HyperHDR, combined with WLED.

You might be able to run an app on your TV, but unless you root it, you will be limited to DRM-free streams. If you have a spare Wyze and HDMI capture card, this is probably the easiest way to grab the video stream. There's no need to run piOS; Hyperion will run fine under Linux, MacOS or Windows using the latest release.

What other ambient light implementations are out there? A cursor look suggest hyperion.ng maybe?

Yeah the github page is a much better starting point.

Creating an ambilight effect requires you to have something that can read the screen to determine what lights to show, so that basically requires decoding and processing a video stream in real time which is beyond the capabilities of most typical MCU's like those used for WLED. There is a project called Hyperion but that requires a full Raspberry Pi and a USB HDMI capture card. There are lots of tutorials for this on YouTube

This is the official repo: https://github.com/hyperion-project/hyperion.ng

Any reason you decided to "reinvent the wheel" instead of using an existing solution like Prismatic or Hyperion?

thought this looks cool for the tech demo but after check it out with a movie demo it looks like it could be a distraction when watching movies since your eyes will be less focus on the movies and distracted by the changing colors on the wall. https://github.com/TBSniller/piccap

Alright. You should check out Hyperion on webOS (which is a video grabber for webOS and PicCap for a user-friendly UI. This solution does require that you root your webOS tho, which I can't do at the moment because my TV got the latest software update that patched the root exploit method. I'm definitely going to try it when possible and see how it works!

Our "killer app" thus far, in terms of useful things that actually require root, is PicCap [1] - which enables low-latency framebuffer capture for DIY Ambilight systems.

In the just-for-fun department, you can replace the default screensaver animation with a bouncing DVD logo. [2]

You can see a list of currently available homebrew apps here: https://repo.webosbrew.org/apps/

You can also block telemetry, updates, etc. (without relying on something like a pihole).
