What VirtuaCam is

VirtuaCam is a free, MIT-licensed virtual camera for Windows that makes video sources available to apps such as Zoom, Microsoft Teams, OBS, and Discord as a standard webcam. Built-in sources include a physical webcam, a window, a display, and a whiteboard. Sources can be combined with picture-in-picture overlays or arranged in an automatic grid. VirtuaCam shares and composites frames using D3D11 GPU resources; its README says frames remain on the GPU unless a receiving app cannot accept GPU samples. Output options range from 640×360 to 3840×2160 at 15–60 fps, in NV12, YUY2, and RGB32. Other programs can publish frames through its shared-frame protocol, then access them from VirtuaCam’s tray menu. The project describes the software as Windows 11 software, and supported-platform information also lists Windows 10/11. The camera DLL requires machine-wide registration, which the installer handles. VirtuaCam does not include a virtual display driver, but can use a display created by an IddCx driver.

Verdict

VirtuaCam provides a free way to present and combine several sources as a webcam on Windows. Its lack of a bundled virtual display driver and the stated GPU-sample exception are worth noting before setup.
