ZMQVirtualCam

A DirectShow source that creates a virtual webcam that can be fed frames using a ZeroMQ connection.

Installation

Simply use the installer for automatic installation, or manual install can be done using regsvr32

regsvr32 32\ZMQVirtualCam.dll

regsvr32 64\ZMQVirtualCam.dll

Uninstall

Simply use the installer for automatic removal. To manually remove the filter use

regsvr32 /u 32\ZMQVirtualCam.dll

regsvr32 /u 64\ZMQVirtualCam.dll

Usage

A Python 3 example is provided in FrameServer. Modify this to send RGB formatted binary images when so requested.

You'll need zmq for Python which can be installed with

pip install pyzmq

Note that you don't have to use Python, just any code that supports the ZeroMQ transport. Which is just about any language out there.
