Windows Native Virtual Camera (NO OBS, NO Screen Capture)

Windows Native Virtual Camera (NO OBS, NO Screen Capture)
Project Description

I need a true Windows virtual webcam that behaves like a real camera device and continuously streams a hard-coded local MP4 video file in a loop.

OBS, screen capture, desktop mirroring, or Media Foundation virtual camera solutions are NOT acceptable.

This must be a native camera implementation that Windows and applications recognize as a real webcam.

Key Requirements (Strict)

NO OBS

NO screen capture

NO desktop recording

NO Media Foundation MFCreateVirtualCamera–only solutions

NO UI interaction required at runtime

If your solution uses OBS internally or relies on application-level virtual cameras, do not bid.

Functional Requirements

Appears as a standard webcam device in Windows

Works with:

Windows Camera app

Chrome / Edge / Firefox (WebRTC)

Zoom / Teams

Streams a single hard-coded video file:

D:\video\demo.mp4


Video loops continuously

Works even if the physical webcam is disabled

Target Platform

Windows 11 (primary)

Windows 10 (optional)

x64 architecture

OEM laptops (HP / Dell / Lenovo)

Accepted Technical Approaches
Preferred

AVStream virtual camera driver

Kernel-mode camera driver

User-mode feeder (FFmpeg / Media Foundation)

Test-signed driver is acceptable

Acceptable

DirectShow virtual camera filter

Proper camera registration

Compatible with modern applications

Not Accepted

Screen capture

Desktop recording

MFCreateVirtualCamera-only solutions

Deliverables

Fully working virtual camera on my system

Source code OR compiled binaries

Installation & setup instructions

Instructions to change video file path (optional)

Acceptance Criteria

Physical webcam disabled → virtual camera still works

Windows Camera app shows the video

Browser camera test pages show the video

Video loops smoothly

No OBS processes running

Timeline
