Introduction

• This is a sort of index page for architectural documents and coding HOWTOs for the MediaPortal-II development. It contains architectural overview pictures, interface descriptions, and some descriptions of important code parts such as the plugin system. If you are a MP-II developer, please feel free to improve this page and add additional developer documentation.

• The MediaPortal2 Development page gives a more general overview of information about the MediaPortal II development.

Architectural overview

• This section contains architectural documents giving an overview of the complete MediaPortal II system.

  • Requirements

  • Overall design

  • Obsolete document of the Goals and Overview (has to be reworked)

Organization of the MP-II directories

• Organization of the MP-II root folder

• Organization of the MP-II source code folder (solution files and all project files)

Executable applications

• Describes all executables built from the MP-II sources and used to support the development.

MP-II executable applications

• Those executables are built by the MP-II build process. They make up the MP-II application which gets installed.

  • MediaPortal.exe (this is the main application of the MediaPortal-II client)

  • ...

Development support applications

• ?BuildReport (Creates HTML reports for an MP-II build)

• ?StringManager (Manages all localization strings used in MP-II)

• ...

Module description

Core services/modules

• Those services are present in the MediaPortal-II core part:

  • Logging

  • Message Broker

  • PathManager - getting system paths

  • Plugin Manager/Plugin system

  • Settings

  • TaskScheduler (to be added)

  • Threading (to be added)

  • FileEventNotifier (to be added)

• Core services are exposed through the ?ServiceScope by their core interface.

Media management modules

• The media management subsystem contains the following modules:

  • (to be added)

UI services/modules

• Services and modules which are additionally present in the MP-II client:

  • Configuration

  • Localization

  • WorkflowManager

  • UserManagement (to be added)

Writing plugins

• Describes the plugin interface and the way how to write plugins (to be added)

MP-II skinning

• The Skinning wiki page describes how to create MediaPortal-II skins

• The SkinEngine page gives some technical background

• The MP-II UI concept page describes the new UI concept

Important application parts and their usage

• This section will focus on some very important application parts and give helpful information for understanding and using them.

Logging

ServiceScope - getting instances of application services

• The ServiceScope class is responsible for holding all application-wide accessible service instances. A service in this context is a piece of code which fulfills a specific function, defined by an interface. A service can be responsible for logging (interface ILogger), messaging (IMessageBroker) or other application tasks. The ServiceScope class supplies methods to get, set and remove a service for a special interface.

• Another important feature of this class is that a new instance of ServiceScope can be stacked upon the current one. When a new ServiceScope instance is created, this one becomes the current service scope, and it inherits all services registered at the former service scope, except those services are registered at the new ServiceScope instance.

• So it is possible to temporarily blend in other service instances for future calls to ServiceScope<...>.Get().

  For more information, see the docs for class MediaPortal.Core.ServiceScope.
