  **Connecting Interfaces**

  For the best experience, you'll want to connect the following interfaces.

     sudo snap connect obs-studio:alsa
     sudo snap connect obs-studio:audio-record
     sudo snap connect obs-studio:avahi-control
     sudo snap connect obs-studio:camera
     sudo snap connect obs-studio:jack1
     sudo snap connect obs-studio:kernel-module-observe

  **NDI**

  If you want to use the NDI plugin you'll need to connect the Avahi Control
  interface.

     snap connect obs-studio:avahi-control

  **Virtual Camera**

  Starting with OBS 26.1.0, Virtual Camera support is integrated. Here's how
  to install and configure `v4l2loopback`:

     sudo snap connect obs-studio:kernel-module-observe
     sudo apt -y install v4l2loopback-dkms v4l2loopback-utils
     echo "options v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual
     Camera'    exclusive_caps=1" | sudo tee
     /etc/modprobe.d/v4l2loopback.conf
     echo "v4l2loopback" | sudo tee /etc/modules-load.d/v4l2loopback.conf
     sudo modprobe -r v4l2loopback
     sudo modprobe v4l2loopback devices=1 video_nr=13 card_label='OBS Virtual
     Camera' exclusive_caps=1

  **NOTE!** Using `video_nr` greater than 64 will not work.

  **Removable Storage**

  To access content on external storage, connect to the removable-media plug:

     snap connect obs-studio:removable-media

  **3rd Party plugins**

  To install pre-compiled plugins, download and extract the plugin to
  `~/snap/obs-studio/current/.config/obs-studio/plugins/`.

  This is how the Input Overlay plugin looks when correctly installed:

     /home/username/snap/obs-studio/current/.config/obs-studio/plugins/
     └── input-overlay
         ├── bin
         │   └── 64bit
         │       └── input-overlay.so
         └── data
             └── locale
                 ├── de-DE.ini
                 ├── en-US.ini
                 └── ru-RU.ini

  If you want to use the Input Overlay plugin, you'll also need to connect
  the joystick interface:

     snap connect obs-studio:joystick
