Confirmed that with v4l2loopback-dkms 0.12.3-1ubuntu0.1, configured
devices are not correctly advertised. This breaks Zoom, Cheese, etc.
Compiling v4l2loopback from upstream source works correctly.

Right now, the only app that appears to work with the new module is
Chromium. Which was where I was testing because that seemed more
demanding. Will be working on the regression on bug 1901491.

Can confirm, this change prevents Zoom from listing my v4l2lsink from
OBS. I had to downgrade to the "base" package so that my co-workers can
continue to see my stupid effects and overlays.

No, looking quickly at the code that should be set in the capabilities
returned by the query capabilities call. But not in the static
device_caps. And if that is added back, one cannot drop that flag for
exclusive_caps functionality without triggering repeated kernel
warnings.

Would loading the new module with exclusive_caps=1 work as a quick work-
around. I guess I missed adding the caps explicitly in the query

The last fix also broke v4l2loopback for me. Most applications seem to
check the V4L2_CAP_VIDEO_CAPTURE flag (eg Firefox:

This fix has rendered v4l2loopback obsolete. Indeed, the device is no longer
detected by any applications (e.g. VLC, Firefox, etc.).

Thanks for the updated debdiff as requested, LGTM now.
Some minor cleanup 0.12.3-1ubuntu1 -> 0.12.3-1ubuntu0.1
Further I think we should add DKMS rebuild with the Focal kernel as

but to be formally correct)
