CastAPI

Cast media to ddp device(s)

DESKTOP: cast your full screen or a window content
    capture frames

MEDIA: cast an image / video / capture device
    capture frames
    cast image with Websocket
    create matrix based on ddp devices... so cast to a BIG one

+
API: FastAPI, for integration with third party application (e.g. Chataigne)

Web GUI based on NiceGUI
