Hello,
Apologies if this is an issue that has already been discussed, but after searching I could not find anything matching this issue.
I have hyperion running on my pi0 using GPIO18 just fine, 5V PSU powers both pi and LEDs, boot and background effects work fine. But when I connect a USB capture card, all I get are solid white LEDs and I do not see any live video feed in hyperion. The lighting is difficult to see here because this picture was taken in daylight, but trust that the LEDs are all showing white.
I have my capture card input coming in from my stereo receiver zone B hdmi out (receiver is set to output to both zones simultaneously, confirmed working with other device). Settings are as follows.
I have tried the following to no avail:
power cycle the pi
start pi before attaching USB capture input (other posts suggested this may work)
verified that all cables are functional
verified Zone B video output working
verified the capture card works on another device
adjusting the USB capture framerate up and down
adjusting the USB capture resolution up and down
changing the Encoding format
changing the Size decimation
Any advice would be very much appreciated, thank you in advance!
