For me, the instructions above did not work.
Running OBS 25.0.4 on Ubuntu 18.04.4, kernel: 5.3.0-46-generic #38~18.04.1-Ubuntu SMP x86_64, I was getting the same error: "Format not support"...
Eventually I succeeded by doing the following:

a. Updated OBS to 25.0.7
b. Downloaded and installed v4l2loopback-dkms_0.12.5-1 from Debian Sid:
https://packages.debian.org/sid/v4l2loopback-dkms;
c. Erased the v4l2loopback module from the kernel, and re-loaded the new v4l2loopback module;
then obs-v4l2sink is working!
