Created attachment 129246 [details] gst-device-monitor-1.0 Video/Source output SUMMARY kamoso recognize my camera but ignore it STEPS TO REPRODUCE 1. Open kamoso OBSERVED RESULT black screen, no cameras inside options EXPECTED RESULT camera works SOFTWARE/OS VERSIONS Operating System: Fedora 32 KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.70.0 Qt Version: 5.13.2 Kernel Version: 5.6.15-300.fc32.x86_64 OS Type: 64-bit Processors: 12 × Intel® Core™ i7-8750H CPU @ 2.20GHz Memory: 15,2 GiB ADDITIONAL INFORMATION after some investigations I noted that m_uid variable in device.c not populated and consequently my cam is ignored by isValid() method, if I populate m_uid variable with any value the cam is not ignored and it works well. I noted also that "gst-device-monitor-1.0 Video/Source" output return udev-probed = false Inside gstreamer sources (https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/blob/master/sys/v4l2/ gstv4l2deviceprovider.c) you can see that sysfs.path is set only for udev probed device (row 249) but not in other case (row 122+)
I maked a merge request with a potential fix for this https://invent.kde.org/multimedia/kamoso/-/merge_requests/4
Fixed with that MR, thanks!
