Virtual Camera Code Adaptation for Windows

I'm looking for a programmer to help me adapt some existing C++ code for a virtual camera system. The code I currently have is in C++ and designed to operate on Windows.

Key aspects of the project:
- **Adaptation**: The task is to take this existing code and modify it to allow the user to switch between different camera modes. I have a specific vision for this system which includes switching between:
- The system camera
- The system camera with a watermark
- A full-screen image

- **Functionality**: The change between these modes should be quick and seamless, and should be implemented through keyboard shortcuts. The user should be able to easily navigate and switch between these modes without any lag or glitches.

I would like you to adapt some code for a simple virtual camera. The basic code is already all here from Microsoft https://github.com/microsoft/Windows-Camera/tree/4825decdbfa8b9ee8ec9d214612874ede9cc2dc7/Samples/VirtualCamera

For this proof of concept with no GUI I would like you to make the code to make the virtual camera to handle 3 states for the virtual camera which users switch between like this, by pressing :

Ctrl+1 - takes system video camera video feed as input

Ctrl+2 - as above but also with watermark image in top right corner.

Ctrl+3 - no camera vision, full screen image

This is a proof of concept.

If it is successful a larger project based on this test will follow.

Thanks.
