nvm! Turns out it's because on this system I previously compiled hyperion. I don't understand much of linux structure but it was in some other obscure location that I now found and deleted.

Hi,
I've been running hyperion.ng alpha 5 for a while on Ubuntu 20.04. Now I want to install version 7. I do that by downloading the latest .deb file and running the following command from the deb file's location:
[H]sudo apt install ./Hyperion-2.0.0-alpha.7-Linux-x86_64.deb[/H]
All good so far, no errors. Then, when I click on the Hyperion icon on the desktop, Hyperion alpha 5 launches.
So aperently alpha 5 is still located somewhere on the system. I followed the official guide and ran the uninstall command
[H]sudo apt remove hyperion \[/H]
Again, not errors, but even then after reinstalling alpha 7, alpha 5 launches when I click the desktop icon.
How do I proceed from here?

Hi,
I've installed the Windows version of Hyperion and have my LEDs through a ESP8266 working, also able to 'grab' the screen of my Windows pc (Platform Capture).

Now i'm trying to use my Android TV and phone (for testing) as in input but can't seem to get them in Hyperion.

For this, i've downloaded the Hyperion Grabber app, set up the correct IP of the server and used the same port for PROTO (19445), but i'm not seeing any of it in the dashboard/remote-control pages, they don't show up as source.

Am i missing something?

Thank you very much.
Thi is working on RPI 3 or only on RPI 4 ?

Edited my previous message

This capture card and tweaking the gamma values in h.ng
Note that the capture card requires usb3 for both the data and the right voltage/amp to work. So it probably doesn't work on a rpi3 but it should on rpi4. I use an ubuntu machine that is running some other stuff like home assistant.

Yea that's because analogue grabbers don't support true black. I've moved to a digital grabber for that reason and since then black=black meaning the leds will actually turn off in dark scenes. Don't get the cheap 10 dollar ones from ali, they are really just analogue ones

I just came across this screen grabber. I used hyperion hdmi grabber setup with Shield + hdmi splitter + RCA grabber + RPi till now. Things work fine for 1080p.

But now thinking of trying it with new 4K TV. I understand that secured content will not work (Netflix), want to make 4k Youtube work.

So I downloaded the APK from playstore on shield, configured the parameters to connect to Hyperion server. And started the screen grabber.
I don't see LED changing. Hyperion server screen grabber shows black screen. I changed grabber setting to internal grabber, anything else I need to change? Where can I find more details?

The phone app (remote control) works fine https://play.google.com/store/…=nl.hyperion.hyperionfree

Also, I want to help the developer what is the best way to do that. I will buy the $0.99 App but think it is too small value.

Yea it doesn't work if you're on android 10. Not sure why but it seems to be a known issue according to the git

and where is the problem?

It's running on my gaming machine and I'd like to save as many resources as possible for actual gaming.

This has been asked before for the original Hyperion software but I couldn't find an answer for hyperion.ng so here goes:
Is it possible to control 2 different LED strips? I know it's possible by running 2 instances but that also uses more resources so I'd rather somehow have a double output.
My setup: Windows 10 - Hyperion.ng release 6. LED hardware: UDPraw. LED strip is connected to a Wemos D1 mini with WLED.

I did manage to downgrade and found out the following:
Netflix is not working on android 7
Netflix is working on latest shield software, but android screen grabber isn't. This is a known issue of this software and there is no known workaround yet.

damn, seems like Im stuck on official firmware 9 and there's no option to root the device atm

This weekend I'll try and look at thr combination of Android screen grabber and this https://forum.xda-developers.c…pto-disabler-drm-t3794393

This app works great on my nVidia Shield TV! I used to have a HDMI grabber, but the app works much simpler and avoids a lot of cable clutter. Avoiding the HDMI grabber's Digital-->Analog-->Digital conversion is also beneficial for noise levels. I've found Plex, Youtube and Spotify to work perfectly with 4K60 content. I only tested HDR in Plex, which works great too.

Netflix (menu and videos) on the Shield does not work, likely due to the DRM/DHCP problems mentioned before. I would like to explore this further, but my knowledge on this is limited. I did get my (rooted) Android phone to work perfectly with the grabber app and Netflix. The Netflix phone app shows it's using Widevine L3 and SD playback resolution.

what steps did you do to get it working with DRM content on your rooted phone? The Shield can also be rooted. Apps can be sideloaded over ADB. I would like to test this because I would love to have less cables and a better picture quality for hyperion without noise/flickering, especially in dark scenes!

I would also like some more detailed information on how to install hyperion.ng
I have trouble getting my sk6812 led strip to work and I've read that the alpha might have better support for it. However, I don't know how to compile and run hyperion.ng. I have found the step-by-step guide.
Running wget -qN https://raw.github.com/hyperio…scripts/docker-compile.sh && chmod +x *.sh && ./docker-compile.sh -t armv7hf
doesn't seem to do anything.

Hello,
I have a SK6812 strip directly connected to a rpi 3b. I only get a single color (white) working on the strip. I have no boot animation and I am not able to change the color using the color picker tool in hypercon.

Setup:
rpi 3b
SK6812. For testing purposes I only have 8 leds connected

Wiring:
DC 5v > strip '5v'
DC gnd > strip 'gnd'
rpi gnd (pin #9) > DC gnd
rpi SPI (pin #19 or #21) > strip 'Do'

hyperion.config.json:

{
        "name"       : "MyHyperionConfig",
        "type"       : "ws2812spi",
        "colorOrder" : "grb"
    },

I use the 'WS281X-SPI' config type because that seems to be the only config type where the leds fire up. I have tried 'WS281X (RPi1, RPi2, RPi3)' with many different config variables but I never got that working on GPIO18 (pin #12).

So: I only get a static white color. I am not able to change it using the color picker and I don't get a boot animation.
What can I do from here?
