Webcam Virtual Driver, CoreMediaIO, DAL plugin

Hello, I need to send my frame to a virtual driver on MacOS. I can't find example to such plugin in MacOs. For example, this minimal plugin (https://github.com/johnboiles/coremediaio-dal-minimal-example) creates its own frame and display it as a virtual driver.
From my C++ application that compiles also Objective-C to link with Macos, I can only find a way to list every device (CMIODeviceID, CMIOStreamID...) with their description.
Thanks.
