There is nothing I can see in /proc or /sys.

vloopback does create video devices in /dev, although there is nothing to
distinguish them from other video devices. The only difference is the way
they are used - one client writes to the in device, and that data can be
read from the out device.

The only thing I can see is with dmesg:
[139226.338844] [vloopback_init] : video4linux loopback driver v1.3
[139226.339881] [vloopback_init] : Loopback 0 registered, input: video2,
output: video3
[139226.339886] [vloopback_init] : Loopback 0 , Using 2 buffers
