The most surprising part of this build is what is missing from it: there is no capture card, no PC, and no Raspberry Pi anywhere in the chain. A GoldHEN plugin running on the PS4 itself reads the console's own video output and pushes the colors straight to a WLED controller over DDP. Everything I used to think this kind of lighting required has been collapsed into software on the console plus the LEDs themselves.
Putting it together looks pleasantly simple for anyone already in that ecosystem. The requirement list is short: a jailbreakable PS4 with GoldHEN, the plugin, and a WLED controller driving the strip. The demo shows multi-zone backlighting behind a wall-mounted TV, with the zones shifting to match whatever is on screen.
The demo material makes the tracking easy to judge. It cycles through EA SPORTS FC 26, Need for Speed Heat, and a color test reel, and the backlight follows along with blue, yellow, magenta, cyan, and a full rainbow wheel sweep. The status overlay reports HDR 10 and Auto 1080p at 60Hz on HDMI1, so it appears to be handling HDR content rather than sidestepping it. Netflix was tested as well, which fits the stated audience of people using a PS4 as a media center.
The open thread here is the PS5. The maker says a version is planned but there is no jailbreakable PS5 on hand to experiment with yet, and they are keen to hear how the plugin behaves across different games. That seems like the right next step to me.
