obs virtual camera install on ubuntu 20.04 fix

install the obs virtual camera on ubuntu 20.04 without compiling anything, the fix is you need to create some directories and a symbolic link then the plugin will work

I also show you how to send the output of obs studio into google hangouts, and use ffmpeg to record your desktop and open the virtual video device with vlc so you can check its working

obs-v4l2sink ubuntu 20.04 install

https://github.com/NapoleonWils0n/cerberus/blob/master/obs-studio/obs-ubuntu.org

obs virtual camera for linux https://github.com/CatxFish/obs-v4l2sink

download the deb file from https://github.com/CatxFish/obs-v4l2sink/releases

install packages:

sudo apt install v4l-utils v4l2loopback-dkms v4l2loopback-utils v4l2sink

install obs-v4l2sink plugiin on ubuntu 20.04

install the deb file sudo dkpg -i obs-v4l2sink.deb

install any missing dependencies

sudo apt install -f

create the symlink create the directory structure for plugin

mkdir -p ~/.config/obs-studio/plugins/v4l2sink/bin/64bit/

create a symlink from the plugin to the directory we created

ln -s /usr/lib/obs-plugins/v4l2sink.so ~/.config/obs-studio/plugins/v4l2sink/bin/64bit/

create the video loopback device

sudo modprobe v4l2loopback devices=1 card_label="OBS Cam" exclusive_caps=1

list the video devices

v4l2-ctl --list-devices in my case the video loopback device is listed as:

/dev/video2 you can also list video device directory ls -l /dev/video* obs tools menu choose v4l2sink from the obs tools menu

and then set the device to the location of your virtual camera, which we found by running the v4l2-ctl command

in my case it was:

/dev/video2

ffmpeg you can also use ffmpeg to send output to the virtual video device outside of obs studio

ffmpeg -f x11grab -r 15 -s 1366x768 -i :0.0+0,0 -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video2
