Plugins Library

Introduction

Let's clarify some of the terms that are frequently mentioned in this chapter:

• a Plugin is a single python module, part of the Plugins Library.

• the Plugins Library is a collection of plugins, developed by Unified Streaming, that comes preinstalled with the Manifest Edit software package.

• the Pipeline Configuration Files are a set of .yaml pre-packaged configuration files (look in in the /usr/share/manifest-edit folder in the supported *nix-based operating systems, or in C:\Program Files\Unified Streaming\ManifestEditConf on Windows).

• We will provide in this documentation many use cases to illustrate Manifest Edit capabilities. A Use Case is implemented by a specific .yaml Pipeline Configuration File, along with the related plugins.

As a Manifest Edit user, it is helpful to have a clear picture of which plugins are included in the Library and what kind of manifest edit logic they implement. This section details plugins currently included in the pre-installed plusing library.
