I have 3 webcams attached to my laptop for a c++/opencv project and my program crashed. Now it keeps giving warnings that "device or resource busy". I suspect this is a OS level error. Is there any way to forcibly unlock my webcams? I'm using 14.04.
So far I have disconnected and reconnected the device and tried to change the permission of /dev/video0 /dev/video1 and /dev/video2 to chmod 777. I have also tried sudo lsof /dev/video0 which didn't work either:
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvf Output information may be incomplete.
I have also tried complete reboots of the laptop. The problem exists both in 2 usb connected webcams and 1 internal webcam.
Software updates haven't helped either and the problem has now been persisting for several days now. Anybody who has any good idea on how to fix this?
