The webcam on the laptop does not work, how to solve the problem?

Question

linux

I urgently needed a webcam on a laptop, and she doesn’t want to work with the law of meanness :(
I installed the cheese program, she sees it, but the video doesn’t want to transmit , I got

the command lsmod |grep video
:

[email protected]:~$ lsmod |grep video
uvcvideo               90112  1
videobuf2_vmalloc      16384  1 uvcvideo
videobuf2_memops       16384  1 videobuf2_vmalloc
videobuf2_v4l2         24576  1 uvcvideo
videobuf2_core         40960  2 uvcvideo,videobuf2_v4l2
videodev              180224  4 uvcvideo,videobuf2_core,videobuf2_v4l2
media                  40960  2 uvcvideo,videodev

what could be the problem?
I have already tried everything, but this problem still does not give in ...
