https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D245507 Bug ID: 245507 Summary: multimedia/webcamd: webcam stops working after some time Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: Individual Port(s) Assignee: hselasky@FreeBSD.org Reporter: jrm@freebsd.org Assignee: hselasky@FreeBSD.org Flags: maintainer-feedback?(hselasky@FreeBSD.org) This is on a Lenovo X220 running 12.1. % webcamd -l | grep Camera webcamd [-d ugen0.3] -N Chicony-Electronics-Co---Ltd--Integrated-Camera -S unknown -M 0 % sudo service webcamd start Starting webcamd. Attached to ugen0.3[0] % pwcview -s vga Webcam set to: 640x480 (vga) at 5 fps Normally this works, but something gets triggered, so that this only brings= up a green screen and the LED on the webcam is not lit up. I've tried restart= ing webcamd, reloading the cuse kernal module and % sudo usbconfig -d ugen0.3 power_off % sudo usbconfig -d ugen0.3 power_on The only way to stop pwcview is to send a kill signal. This text is then reported: Webcam set to: 640x480 (vga) at 5 fps ^Clibv4l2: error dequeuing buf: Device not configured Error reading from webcam: Device not configured A wild guess is that some process is blocking something, but I have yet to = find a culprit. I believe the only fix is to restart the laptop. I will confirm this later. --=20 You are receiving this mail because: You are the assignee for the bug.=
