Public bug reported: on Unbuntu 20.04 LTS with v4l2loopback-dkms v0.12.3-1ubuntu0.1
The kernel module loads fine, but none of the applications or utilities that try to connect to the loopback device can use it. They report various things from "device" busy to "Device '/dev/video5' is not a output device." (from gst-launch-1.0) It seems this is a known problem:https://github.com/umlaeute/v4l2loopback/issues/370 The solution is to force install the same package from 20.10 v4l2loopback-dkms_0.12.5-1_all.deb ** Affects: v4l2loopback (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1903926 Title: Device '/dev/video1' is not a output device - While device seen as output by v4l2-ctl To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/v4l2loopback/+bug/1903926/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
