Hi Laurent!
Nothing works with 1.11 release host packages... Reports are included. Everything is reproducible.
I was not able to try to rebuild it yet (lack of time). But, if you are really interested to find what’s going on and want to fix it – I can provide you remote access to my hardware (Ubuntu, SSH, VNC, xRDP etc) with physical webcam attached. Just e-mail me.
BTW, OpenCV package for Ubuntu 18.04 in your repo is still in beta state.
