What it does

The obs-virtual-cam plugin simulates a DirectShow webcam, allowing you to use OBS Studio as a virtual camera in other applications.

When to use it

•You need to use OBS Studio's video processing capabilities as a virtual camera in video conferencing software.
•You want to use OBS Studio's plugins and effects in live streaming or screen recording applications that only support DirectShow webcams.
•You need to test or debug video applications that rely on DirectShow webcams.

Ready-to-paste prompt

To use the virtual camera in a video conferencing application like Skype, select 'OBS-Camera' as the video device in Skype's settings after starting the virtual camera in OBS Studio

Heads up: The plugin requires OBS Studio 24.0 or later to be installed, and the plugin must be built for the same architecture (32-bit or 64-bit) as the OBS Studio installation
