My camera led is flashing (it’s a sign that it’s in use), but there is no app that I know of currently using the camera. If I try to launch an app that has camera support, it says the camera is not available (another sign that the camera is in use).
The first row of lsmod shows there’s zero processes using the camera.
$ lsmod | grep uvcvideo
uvcvideo 114688 0
videobuf2_vmalloc 20480 1 uvcvideo
videobuf2_v4l2 36864 1 uvcvideo
videobuf2_common 65536 2 videobuf2_v4l2,uvcvideo
videodev 294912 3 videobuf2_v4l2,uvcvideo,videobuf2_common
mc 61440 4 videodev,videobuf2_v4l2,uvcvideo,videobuf2_common
also lsof and fuser show no output at all.
$ lsof /dev/video0
$ fuser /dev/video0
So what now? How can I find and kill that bastard process?
