Certainly yes.

```
$ lsmod | grep v4l
videobuf2_v4l2         24576  1 uvcvideo
videobuf2_common       45056  2 videobuf2_v4l2,uvcvideo
v4l2loopback           45056  0
videodev              225280  4 videobuf2_v4l2,v4l2loopback,uvcvideo,videobuf2_common
mc                     49152  5 videodev,snd_usb_audio,videobuf2_v4l2,uvcvideo,videobuf2_common
