And, even without OBS, all the instructions out there to capture and share specific screens (or portions of screens) in Linux using apps like Slack describe using v4l2loopback. I'm already using OBS. I use OBS to prepare the scene by combining all the sources into the scene layout I want, but then I need to expose that result into an output stream that can be used in Slack or other apps. There are OBS plugins to emit the scene to a virtual video capture device, and it works on Windows just fine, but for it to work on Linux, I need to use the v4l2loopback module to create a virtual camera that can be used in those streaming apps. As I understand it, v4l2loopback is already available on Ubuntu. There was a COPR package for it, but it hasn't been maintained in some time, and even when bringing it up-to-date, it uses DKMS to build an unsigned kernel module, which won't load. I'm not comfortable messing with mokutil and SecureBoot configuration, and don't think it should be necessary to get this functionality. _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
