Obs Mac Virtualcam

This project is a macOS system camera driver and software plugin that exposes software video streams as hardware-recognized camera inputs. It functions as an OBS virtual camera plugin, allowing the live output of OBS to be utilized as a webcam device within other applications.

The tool enables the routing of composited video from a production suite into video conferencing applications such as Zoom or Google Meet. This allows for the streaming of processed scenes instead of a raw webcam feed.

The system integrates with macOS using a kernel-level device driver and shared-memory buffer transfers to move video frames from the application process to the operating system. It utilizes the CoreMedia framework to handle video stream timing and metadata.

Features

  • Virtual Camera Integration - Bridges processed OBS media into standard communication software as a virtual camera device.
  • Kernel-Userspace Shared Memory - Uses a high-speed shared memory region to transfer raw video frames between user-space and the kernel driver.
  • OBS Plugins - Functions as a plugin for OBS Studio to share processed video feeds with system-level camera applications.
  • Virtual Camera Plugins - Provides an OBS plugin that creates a virtual webcam device from the live output of the studio.
  • Virtual Camera Drivers - Implements a virtual camera driver for macOS that emulates physical camera hardware.
  • Virtual Video Routing - Exposes software video output as a system camera device for use in external video conferencing apps.
  • Device Drivers - Provides a kernel-level device driver that creates a virtual video device recognized by the operating system.
  • Video Frame Synchronization - Synchronizes the application render loop with the driver polling rate to ensure smooth video output.
  • Video Conferencing Integrations - Enhances video conferencing calls by allowing professional composited scenes to be used as the camera feed.
  • Inter-Process Communication Bridges - Implements a communication bridge between the user-space OBS plugin and the system-level kernel driver.
