Try this and see if it works:

sudo systemctl disable --now hyperion@pi sudo systemctl enable --now hyperion@root

If it doesn't work then go to this link and down to Preparation and installation section (I didn't have to do that with new hyperbian)

I built an hyperion ambilight setup but cannot get the lights to work. I'm sure that to someone with more experience, this will be easy to resolve. I've attached the debug log. TIA!

Whats your setup?

leds, how you connect them etc.

Hey, since we have pi shortage and the only ones available are over $100 i was wondering if anyone is using the Raspberry Pi 2 Zero W Quad Core for hyperion and a grabber? Last time i used the single core zero it was ok but laggy.

Thanks!

you also run it on your windows PC the hyperion and use nodemCU for wireless transmission with Wled

or buy them off on Aliexpress/ebay or such

Do you know if anyone tried using Banana Pi or Orange Pi 4?

So with the world wide chip shortage and Raspberry Pis not being available , did any of you get creative with some alternative solutions?

I just updated to the newest hyperbian and I found out that the setting to switch from rgb to grb disappeared. I'm using WS2812B hooked up to RPI 3 B+ through pmw 12. On old hyperbian I could switch from RGB to GRB but on the new one I don't see that option anywhere. Any ideas? Maybe I can still edit it in the config file?

If anyone is interested following splitter/capture card seems to bypass the hdmi copy protection. Tested it for few hours and it works! No more noise/no signal screen!

Not exactly, for example this card has pass through, and works well

https://www.amazon.de/-/en/gp/produc…00?ie=UTF8&th=1

But the question is what do you need. Personally i needed CEC, this card doesn't pass through that information. So i had to buy a splitter for that.

Basically I want to just be able to connect the card to the media device (console, firetv etc.) and have a split one to hdmi and one to raspberry usb. Every single Splitter with loop I tried had the issue of static (no signal) because of the hdmi protection. Does the one you linked ignore the hdmi protection?

Hey so from my understanding if you want the capture card to work properly you need a splitter that supports hdcp right?

Has anyone tried this one?

don't know grabbers with LOOP, but the one i have is from Xolorspace type 61121 and works really well

Do you think that rpi 4 would recognize hdmi to usb cable? It is compatible with Linux

Quote from Lighting-guy77

only way to fix this is use of a good splitter which supports EDID/HDCP

Do you know of any usb grabber with loop that would work and wont break the bank? (under $100)

Yes tried all the settings still not working

did you set these?

Go to the WebUI and menu USB grabber;

Device; USB video: USB video

Input; Camera1 ( or higher)

Resolution; in 16/9 lowest as possible and then build up the resolution

Size decimation; set to at least 4 until 12 >> the higher count, the worse image

Frames a second; 15FPS or go lower and higher.

Display More

These are my current setting:

Hey I have this weird issue, I did everything you said and everything works fine as long as I don't restart the pi. When the pi reboots the usb device still shows in hyperion but I get white signal noise instead of hdmi capture. Only way to fix it is to unplug hdmi from my xbox and plug it back in.

about to give up. Nothing works consistently.

Gone through 3 splitters ( a normal 4k splitter, second a 4K splitter with EDID switch and now a 4K splitter with downscale switch)

Gone through 2 capture cards

Nothing works. After a few minutes Hyperion resorts back to idle LED effect which for me is rainbow color. Looks good but I want ambilight im thinking its a capture card issue

in a last ditch effort I may try HDMI to RCA > RCA Capture Card to see if this will actually work. if not im done.

I'm telling you the 4k capture cards get powered from the PI's usb. PI's usb can only supply 600ma (1.2a on newer models) and 4K 60hz capture card needs more power to keep the signal. I had the same issue and got a powered 4k usb capture card with hdmi loop.
Also the hdmi to rca to usb worked very well for me but I wanted a little more simple set up to fit it into an enclosure.

I dont think that does much to help me but thank you.

upon further research it seems the RPi has issues with 4K signals. I need to down convert the signal before it gets to the RPi. I think my best bet is Splitter > HMDI to RCA converter > RCA to USB Capture Card. The signal would be 480i going into the RPi which would work well for me as the 4k signal would still go to the soundbar

As it currently stands if I use my Apple TV 4K or PS4 Pro with 4K signal, the signal cuts and Hyperion goes back into idle effect two seconds after starting but If I force a 1080p signal it works flawlessly.

well from what I saw your usb grabber doesn't have it's own power and pi can't supply it for 4k, the one I linked has it's own power that you would plug into your 5v 15a supply that way it won't get powered through the pi.

HI! youv ebeen a great help.

so i just set up the splitter with EDID. What i notice is the EDID splitter seems to limit my resolution output to my soundbar(which then goes ARC to my TV so I can maintain ATMOS) but im testing it on PS4 Pro. the splitter seems to cap the PS4 Pro at 1080P and when it does that the Hyperion works flawlessly. Yet whenever I flip the switch to uncap just the signal going to soundbar > TV and the signal is 4K on my TV, Hyperion stops working immediately for some reason. Is the splitter choosing the 1080p capped signal to my capture card as the master signal and therefor capping the output to the sounbar/tv to 1080p as well to match?

maybe i need to buy a downscaler to get this thing to work properly :thumbsdown:

I'm using this splitter it has a loop out for hdmi so you plug in hdmi in and you have hdmi out yo your tv and usb out to raspberry

Isn't the response slow when the led turns on?

What product did you use?

For me also the response of the leds and the colors are amazing. 0 delay all I had to do is lower down the resolution in the hyperion ng web config for the usb grabber. Very hapoy with it.

Re:
I just tested it.
It works perfectly with Raspberry Pi 4. All you need to make sure is that you power the grabber separately with a good power supply.
My specs are:
Rpi4
Hyperbian latest update
Ws2812b
10a 5v power supply running everything

Hello I've been looking to fix an issue I have. What I found out is that the hdmi grabber I'm currently using doesn't support 60hz and because of that it doesn't always work.
I was looking at this grabber and I was wondering if anyone has tried it? I have a raspberry pi4 with 3.0 usb ports so hardware wise it should all be ok. Im just wondering of linux supports grabbers like that.
