hyperion web ui wont let me save usb capture

Michael251003 · Oct 26th 2025

Hi there, i seem to be having a problem where hyperion sees the capture card but wont let me save settings when adding it in, the 'save settings' is greyed out not letting me save it. have tried replugging in the capture card to a different usb port and also rebooting the pi with still no luck.

using rasberry pi 3

please see attached image below

thanks

The hardware values from the grabber can't be OK.

Hardware hue control -8193.

Click Default hardware controls and see if the values change.

Hi, sorry for the late reply. so after clicking defualt settings, the hue value stays the same. It was working perfectly before i had an incident with the led strip

After clicking default settings, do you have a live video in Hyperion?

In the live video, you can click "Show LEDs" to see which colors are being sent from Hyperion to the LEDs.

Do colors and effects work in Hyperion?

Incident with the led strip?

Please also attach a Hyperion debug log as Hyperion-log.txt

Hi there, after clicking defualt settings, I dont get a live video but i can see the number of leds.

colours and effects work perfectly

Short cable from the led strip got a bit too warm and melted which is my bad for not adding voltage further down the strip to space out the current.

hyperion debug below (hopefully this is what you need):

Which capture device are you using?

Please post the output of `usb-devices (from the terminal).

Test the capture device on your PC using VLC, OBS, or similar programs.

Attach a complete log file.

Click Copy log to Clipboard, paste it into a text editor, save it as hyperion-log.txt, and attach it here.

So the capture device is what i bought from ali express. it works when using it on a pc and heres the link to what it is.

4K USB 3.0 Video Capture Card HDMI-compatible 1080P 60Hz HD Video Recorder Grabber For PS4 OBS Game Recording Live Streaming - AliExpress 7

hopefully ive done this correctly, thankyou for the help!

I’m guessing it just might be worth reinstalling hyperion on the ras and see if that solves these issues

Please post the output of `usb-devices and v4l2-ctl --all(from the terminal).

Then we can compare the grabber values with the output in Hyperion. Normally, these loop-out cards do not offer hardware control capabilities.

Reinstalling Hyperion does not delete the settings; if you delete the hyperion.db file, you start completely from scratch without a reinstallation.
