piccap VS HyperHDR

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).

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.

This page https://github.com/awawa-dev/HyperHDR/wiki/Level-Shifter shows that a level shifter (3v3 to 5v) is needed for your lights.

I spent a lot of time looking into this. Didn't want to lose HRD to implement Hyperion. I found the HyperHDR fork. Which will convert HRD signal to SDR and works really well out of the box. only thing I had to update was to turn the brightness down in the capture settings. Found a HDMI splitter on Amazon that handles CEC pass through. I lost Dolby Vision, because I couldn't find a splitter that will downgrade dolby vision to 1080p for the capture card. But I had to be honest with myself, I can't tell the difference between Dolby Vision and HDR 10+. Now I have an ambient light solution that allows me to keep HDR without dropping big bucks on something like HD Fury. Very Happy, works with HA still too.
