Description

Implementation of subsystem lifecycle behaviour for the core parts of Steam-Layer.

• The »session subsystem« is responsible for accepting operations to work on the session datastructure, and it will trigger the Builder to reflect those changes into a suitable render nodes network
• The »play out subsystem« is able to perform such a render nodes network for video playback and rendering.

lumiera::Subsys and lumiera::SubsystemRunner together define a protocol for some large scale building blocks of the whole application to be started and terminated. Typically this entails to create a dedicated thread to manage the top level concerns for the given subsystem, and to create registration and services for public access:

• to operate on the session, use the steam::control::SessionCommand facade
• playback and render operations can be operated by the lumiera::Play facade
