Cannot get feed from v4l2loopback

[Harvara]

I worked my way through the setup and had a few problems due secure boot and needed to sign the modules by myself. Now I can run the prepare file (I still get PulseAudio errors) and get the message my device is ready at /dev/video04 and "Press enter to end stream".

If I stop it, is get:

You have to specify a module index or name

But if I try to use it, I just get a black feed in Chrome/Teams and an error in vlc. I tried another setup where i could successfully stream my desktop as webcam signal, but it wont work with the ipwebcam-server.

My feed.log has:

Which OS are you using? I've never seen this issue before.

[Harvara]

Ubuntu 18.04.4 LTS

I am using this awesome script for just two days and it works perfectly. Also the OS I am using is `Ubuntu 18' so you should not have any problem . First run script for installing some dependencies and the after the first time, second you can run it to simulate a virtual video device. I am using with Skype and it works fine.

output for the second time

Trying to install gstreamer1.0-pulseaudio package.

gstreamer1.0-pulseaudio is already the newest version (1.14.5-0ubuntu1~18.04.1).
The following packages were automatically installed and are no longer required:
  cmake-data libjsoncpp1 librhash0 libuv1
Use 'sudo apt autoremove' to remove them.

Please start IP Webcam or IP Webcam Pro server and press Enter

Press enter to end stream

Also make sure to change the IP of the IP-webcam with the one in the script if you use WIFI. but if you use a cable for connection to the OS, (via adb) I think you do not need it.

WIFI_IP=192.168.1.4
