This is resolved. I determined that the issue was that they power source for the pi was not providing enough power. I was trying to run it off of the same power supply that was running the LEDs. I moved it to it own dedicated power supply which is running off of the USB port on the TV. Since doing that I have not had any problems.

Not sure what I'm looking at but it looks like it is seeing the capture card, but I could be totally wrong on that.

I have added the output as an attachment.

Do I need to put those pieces of code in the config.txt?

Yeah I have tried with two screen capture devices and have the same problem. It seems that since upgrading to the latest version the problem has gotten worse.

I'm still seeing the same error in the logs.

The LED's run for about a minute and then everything on the display goes blank for a few seconds and then video comes back on but the LED's do not.

If I toggle the GPIO status from off to on the LEDs come on for a few seconds and then the same problem happens. Screen goes black LEDs go off then after a few seconds the video comes back and the LEDs stay off.

The issue has gotten worse. I'm wondering if it is a power issue. Now with the GPIO off it appears the capture card stops (loosing video) and then comes back a few seconds later. This happens every 30 seconds or so. I'm going to bypass the capture card until we can figure out what is causing the issue.

Could it be power related? Is the Pi Zero able to power the capture card and the LEDs?

Hello,

I'm having issues where it looks like my capture device is shutting down. I have tried trouble shooting but I'm still having the issue. I have modified the config.txt for max_usb_current=1 but it appears that the device keeps shutting off. I can reboot the device and it will run for a few minutes and then shut off again. I am running on a Raspberry pi Zero. Any advice other than upgrading the Pi?

This is the capture card I am using.
