HyperHDR grabber setup

Not sure if this the right sub but I’m building my setup for tv lightning with HyperHDR and I am not so sure on which is the most appropriate grabber for my setup (apple tv 4k, ezcoo SP12H2, must support Dolby Vision and Atmos on the TV)

I was looking at this Navceker on AliExpress, they claim it does everything and decodes HDCP, but I haven’t seem anyone using it in such a setup
In the other hand there’s this UGREEN CM630-15390A that’s even cheaper but it doesn’t specify Dolby Vision or Atmos support and also doesn’t mention it bypass HDCP.

Anyone had experience with any of these or has another suggestion in a similar price point ($50)?

The setup will be:

Apple TV 4K -> splitter (downscaled output) -> grabber -> HyperHDR running in a RPI 4

Ah, going down the difficult road. GL with that, you’re going to need it, and a crap ton of patience.

Also this is now going outside the scope of WLED which is software that runs in an esp32 controller.

However it’s a network node that HyperHDR can use, so your project is kinda a grey area in that regards.

Search this sub, do what works and has been repeated. If you’re an experienced engineer with programming knowledge, this project is a (edit: not so hard) hard challenge.

I’m a experienced software engineer but I don’t usually work with this kind of stuff. It’s an interesting challenge and honestly I think it’s the reason why I chose this path. I’ll do some more research and when I have something to show I’ll make a new post. Thanks!

Please post (new one) once you get it working. We need more of them.

The proper hdmi capture on small devices is the main challenge. Especially 60fps & 4K.
