Is there a way to have a background subtractor automatically ignore an area of the video that is always changing such as an LED screen so that doesn't constantly show as foreground?

I don't think so. But if you know where is your led you can clear it using a mask...

@LBerger yeah, I was hoping to have it not require manual intervention or be subject to issues if moved slightly

If it is periodic and you know the period, you may be able to look for the specified intensity and pattern and use a mask to clear it.
