An NMOS C++ Implementation

Introduction

This repository contains an implementation of the AMWA Networked Media Open Specifications in C++, licensed under the terms of the Apache License 2.0.

NMOS Discovery and Registration Specification (IS-04)
NMOS Connection Management Specification (IS-05)

This software is a work in progress, tracking the ongoing development of the NMOS specifications in the AMWA Networked Media Incubator. For more information about AMWA, NMOS and the Networked Media Incubator, please refer to http://amwa.tv/.

The nmos module includes implementations of the NMOS Node, Registration and Query APIs, and the NMOS Connection API.
The nmos-cpp-registry application provides a simple but functional instance of an NMOS Registration & Discovery System (RDS), utilising the nmos module.
The nmos-cpp-node application provides an example NMOS Node, also utilising the nmos module.

The repository structure, and the external dependencies, are outlined in the documentation.

Getting Started

The codebase is intended to be portable, and the nmos-cpp CMake project can be built on at least Windows and Linux.

After setting up the dependencies, follow these instructions to build nmos-cpp on your platform, and run the test suite.

Next, try out the registry and node applications in the tutorial.

Work In Progress

The implementation is functional and has been used successfully in several Networked Media Incubator workshop "plug-fests", interoperating with other NMOS implementations.

The implementation is incomplete in some areas. Development is ongoing! The NMOS specifications are being continuously developed, as enhancements are proposed and prototyped by the Incubator participants.

Other open-source NMOS implementations:

BBC Reference Implementation, in Python
Streampunk Ledger, in Node.js

Active Development

The nmos-cpp-node example application has been recently added, as well as cross-platform build support using CMake.

In the next few weeks, we intend to bring to this repository:

More of a unit test suite, and automated integration testing (the AMWA NMOS Automated Testing Activity is also a work in progress)
Additional documentation
Back-end enhancements as part of the NMOS Scalability Activity

And of course, the software will continue to be updated to track the ongoing development of the NMOS specifications, and the work of the Networked Media Incubator.
