libNDI

libNDI is an implementation of the NewTek NDI (Network Device Interface) Software Development Kit for macOS. It gives developers access to the NDI protocol, allowing applications to discover, send, and receive high‑quality video and audio streams over standard IP networks without requiring dedicated cabling or hardware.

The library is aimed at software engineers building media‑centric tools, broadcast workflows, live‑production systems, or any application that needs to integrate video connectivity over a network on Apple platforms. By exposing the NDI API, libNDI enables developers to embed real‑time video transport, low‑latency monitoring, and multi‑camera switching directly into their macOS applications.

What sets libNDI apart is its focus on the macOS environment, providing a stable, production‑ready SDK that aligns with the broader NDI ecosystem. It allows macOS developers to leverage the same network‑based video capabilities used in other platforms, facilitating cross‑platform interoperability while keeping the integration process native to Apple’s development stack.
