I executed the following command in terminal and got the output:
Command:
lsmod | grep uvcvideo
Output:
uvcvideo 86016 0
videobuf2_vmalloc 16384 1 uvcvideo
videobuf2_v4l2 24576 1 uvcvideo
videobuf2_core 40960 2 videobuf2_v4l2,uvcvideo
videodev 184320 3 videobuf2_core,videobuf2_v4l2,uvcvideo
media 40960 2 videodev,uvcvideo
Does it mean my webcam is using by some application? I am running no application that uses my webcam and LED is not blinking.
