    Hello,

    Recently, my SD card has failed, leading me to reinstall Hyperion on my rpi3 and stumbled upon an issue i couldn't resolve, no matter google searches or AI help: no output from the USB capture card.

    Parts:

    - cheap AliExpress USB capture card (changed it, same issue)

    - powered HDMI splitter from AliExpress ( working, outputs the image from laptop-> TV)

    What I've tried:

    - Change the capture card to the same model and to another model, still black image.

    - ffplay and v4l2-ctl:

    USB Video: USB Video (usb-3f980000.usb-1.4): /dev/video0 /dev/video1 /dev/media2

    libavutil 57. 28.100 / 57. 28.100

    libavcodec 59. 37.100 / 59. 37.100

    libavformat 59. 27.100 / 59. 27.100

    libavdevice 59. 7.100 / 59. 7.100

    libavfilter 8. 44.100 / 8. 44.100

    libswscale 6. 7.100 / 6. 7.100

    libswresample 4. 7.100 / 4. 7.100

    libpostproc 56. 6.100 / 56. 6.100

    /dev/video0: Device or resource busy

    - tried setting up mmpeg or yyuvm, framerate changes from 5 to 20

    -capture card is active, selected, and detected

    - signal detection on and off

    - As input, I was and am using a Google TV 4k, tried with a laptop as input, nothing changed

    - installed Hyperion as a service from RPiOS Lite and downloaded and installed the standalone image - nothing changed

    - tried multiple resolutions


    Also, when selecting the ws281x in the LED output, by default, I'm not able to use it because I'm not root - I have to grant it manually.

    Mainly, I have changed nothing in the config compared to the previous config, before the SD card failed; however, it's not working.

    Am I missing something or doing something wrong?

    Thank you very much!
