I have the same problem, but installing v4l2loopback from Github does not help. Every Format still fails with _format not support_ I'm running Ubuntu 19.10. ``` v4l2-ctl --list-formats ioctl: VIDIOC_ENUM_FMT...

Thank you for the answer. For an other reason in downgraded my system to Ubuntu 18.04.4 LTS and it worked as documented.
