RE: Black image from capture card

[…]

If the grabber produces a black image, it is likely that the the brightness is set to zero.

To get this corrected:

a) Switch to Expert Setting
b) Check the Control values (see 1.)
c) Press Button "Default Hardware controls" (2.)


d) The Control Values should have changed (3.)



e) Click Save (4.)

Would be great, if you could report back, if that worked.

I updated the Release notes to ensure that people can find this easily.
[…]

see the documentation on PWM Prerequisites (Controller type RPi PWM/ws281x)…

and review the grabber‘s hardware control settings.

You should be able to do this via the following sequence via the command line for Hyperion version 2.1.x

hyperiond -i --exportConfig "."

hyperiond  -i —deleteDatabase

hyperiond -i --importConfig ./HyperionBackup__*.json

You might need to check the syntax, as I am not at my desk…

Quote from Him

Side note: does hyperion have some kind of schedule feature? I like it when my lights turn on in the evening

Have a look at the Scheduled Events configuration.

Not sure, if I see the screenshots correctly.

Looks like your green screen areas result in a red LED color.

This indicates that your LEDs device‘s Color order is not set correctly.

Just run Hyperion‘s Color Order Wizard from the top menu (Magic Wand icon)

You should now see a non black image in the preview. when selecting the ws281x in the LED output, by default, I'm not able to use it because I'm not root

see the documentation on PWM Prerequisites (Controller type RPi PWM/ws281x) and the link how to change the service user.

How did you install Hyperion initially?

Via the easy install script?

What does the following command report?

systemctl status hyperion@${USER}

The HA API is not made for low latency updates. In case you have network lights which are directly supported by Hyperion, always go via the non HA route.

For your lights you might need to check where the latency comes from. Given you are not sharing too much details, it is hard to say.

Latency could happen as Hyperion does requests via a bad Wi-Fi connection.

To sort this out you could enable Debug logging in Hyperion.

There you will then see how long one API request to HA takes.

In case, you issue is more that you do not see frequent updates, you might want to test if reducing the latch time helps.

You should enable expert settings to see the element. You should not reduce the latchtime below the API request time (you checked above). Also include some buffer.

Hoping that this provided you with some pointers.

As every setup is different you need to explored the influencing dimensions.

You need to install the latest Nightly Build

Alternatively in 2.1.1 you could disable an instance before stopping Hyperion.

When you bring it up next time, the instance is still disabled and grabber stopped.

Quote from Thinner

BTW: Build on Raspian Bullseye will fail too, because of QT5 support has been removed and there is no native QT6 support for Bullseye, only a non-supported backport solution, that's why a had to upgrade (fresh install) to Bookworm. Maybe you want to update SupportedPlatforms.md.

Maybe you would like to use our docker images to build for Bullseye?

We build on bullseye with Qt 6.4.2

Hi Thinner

I will not be able looking into things the next two weeks.

Maybe Paulchen-Panther could have a look at the build related issues if he finds time.

PS: Need to look at the cropping config issue again and describe it better…

xdtj777 It is enough, if you create an issue at GitHub. No need to duplicate….

Is there anything in the Kodi log?

I am not familiar with Promox nor LCX, but did you ensure that network traffic in both directions is feasible?

It look like that the Hyperion response is not received by the Kodi add-on why the Next message is not send and then Hyperion drops the session because of timeout.

FYI, I think I found the root cause of the flickering. It is caused by the DDA Grabber.

Given that the Grabber has various issues, we are currently rewriting much of it.

Therefore, we ask for everybody’s patience until a new version is ready for testing.

Edit: Which WLED Version are you using?

There are know issues with the Windows grabbers and the WLED might break Hyperion.

To ring-fence your WLED issue, it would be good to have debug logs.

What happends, if you press the button "Default hardware controls"?

If you hover with the mouse over the values, does it show at an element that the value should be in a certain range?
If yes, update that element.

Is there any change, when you change Hue to a positive number?

If you still have access to the old PC, it would be the easiest to copy the configuration database. The location you find on the About page.

Stop Hyperion on both PCs. Then copy the old configuration and replace the current configuration .dB file on the new PC.

Alternatively, install 2.1.1on the old PC and then export the configuration.
