That 'original_module exists' means that there's already another package providing the driver. I wonder if you have conflicting installs of the package from copr and the one in rpmfusion?
Is the v4l2loopback kernel module loaded? Do you see it in the output of 'lsmod'? Can you run 'modprobe v4l2loopback'? Is there anything in the kernel 'dmesg' after you load it?
The answers to all your questions is YES, but 'dmesg' returns the following:
