Turn on USB Power (RPi) when webcam stream starts and turn off after X seconds Or when stream stops

I hope this is the right area to post this, but I have a small LED strip attached to the USB on my RPi that I'd like to run the command

echo '1-1' |sudo tee /sys/bus/usb/drivers/usb/bind

when the webcam stream starts when accessed via HTTP and run the unbind command either after a some seconds (~30) or when the stream stops (assuming it does after one closes the window or moves to another part of the OctoPrint site). Is this possible?

Thank you in advance.

There's another thread on here where we're discussing something similar.
