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!
