Cheese And Skype Do Not Find Virtual Camera

$ lsmod | grep webcamstudio

Use gstreamer to send sample video to /dev/video0
$ gst-launch-0.10 ximagesrc use-damage=0 ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)YUY2" ! v4l2sink device=/dev/video0

$ sudo webcamstudio
"Detected Video Devices"
  WSVideoDevice (0x0000) (0)
"Output"
 "WebcamStudio Virtual Cam"
   "Pixel Format": RGB24
   "Dummy video device (0x0000) (2)" //from "$ sudo modprobe v4l2loopback" which was done second
   "WSVideoDevice (0x0001) (1)" //from "$ sudo modprobe webcamstudio devices=2" which was done first

Open Cheese
  "No device found"
Skype behaves the same way.
WebcamStudio not only finds the input device, but also lists both output devices that are of the modules "webcamstudio" and "v4l2loopback"

Let me know if there is a more appropriate package that this "bug" should be submitted to.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.

Ubuntu 15.04 (vivid) reached end-of-life on February 4, 2016.

Do you still see a problem related to the one that you reported in a currently supported version of Ubuntu? Please let us know if you do and in which version of Ubuntu otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.

I am having this problem right now. I can control my nikon dslr with gphoto2 and v4l2loopback, but no n other app can see the camera. I am using Linux Mint 19.3.
