Another pertinent theme is to make the basic building blocks simpler, while on the other hand gaining much more flexibility for combining these building blocks. For example we try to unfold any &quot;internal-multi&quot; effects into separate instances (e.g. the possibility of having an arbitrary number of single masks at any point of the pipeline instead of having one special masking facility encompassing multiple sub-masks. Similarly, we treat the Objects in the EDL in a more uniform manner and gain the possibility to [[place|Placement]] them in various ways.

[&gt;img[Anatomy of a Layer Separation Interface|uml/fig132869.png]]
The goal is for the interface to remain fairly transparent for the client and to get an automatic lifecycle management.
To implement such a structure, each layer separation interface actually is comprised of several parts:
* an C Language Interface (&quot;CL Interface&quot;) to be installed into the InterfaceSystem
* a facade interface defining the respective abstractions in terms of the implementation language (C or C++)
* a implementation object on the service proiding side which is directly addressed by the implementation instantiated within the InterfaceSystem
* a proxy object on the client side, which usually is given inline alongside with the CLI interface definition.
* an C Language Interface (&quot;''CL Interface''&quot;) to be installed into the InterfaceSystem
* a ''facade interface'' defining the respective abstractions in terms of the client side impl. language (C or C++)
* a ''service implementation'' directly addressed by the implementation instantiated within the InterfaceSystem
* a ''facade proxy'' object on the client side, which usually is given inline alongside with the CL interface definition.
!opening and closing
Handling the lifecycle can be tricky, because client- and service-side need to carry out the opening and closing operations in sync and observing a specific call order to ensure calls get blocked already on the client side unless the whole interface compound is really up and running. To add to this complexity, plugins and built-in interfaces are handled differently regarding the question who is in charge of the lifecycle: interfaces are installed on the service side, whereas the loading of plugins is triggered from client side by requesting the plugin from the loader.
Anyway, interfaces are resources which best should be managed automatically. At least within the C++ part of the application we can ensure this by using a handle class. This way the handling of plugins and interfaces can be unified; the only remaining difference is on what side (client or service provider side) the handle is instantiated, with the appropriate ctor parameters.
Anyway, interfaces are resources which best should be managed automatically. At least within the C++ part of the application we can ensure this by using the InstanceHandle template. This way the handling of plugins and interfaces can be unified and the opening and closing of the facade proxy happens automatically.
The general idea is, that each facade interface actually provides access to a specific service; there will always be a single implementation object somewhere, which can be thought of as acting as &quot;the&quot; service. This service-providing object will then contain the mentioned InstanceHandle; thus, its lifecycle becomes identical with the service lifecycle.
* when the service relies on a [[plugin|LumieraPlugin]], this service providing object (containing the InstanceHandle) needs to sit at the service accessing side (as the plugin may not yet be loaded and someone has to pull it up).
* otherwise, when the service is just an interface to an already loaded facility, the service providing object (containing the InstanceHandle) will live on the service providing side, not the client side. Then the ctor of the service providing object needs to be able to access an interface instance definition (&amp;rarr; InterfaceSystem); the only difference to the plugin case is to create the InstanceHandle with a different ctor, passing the interface and the implementing instance.

As a prerequisite, a viewer has to be prepared within the GUI. A XV video display widget is wired up to a sigc++ signal slot, using the Glib::Dispatcher to forward calls from the play process thread to the GTK main event loop thread. When doing so, additionally a Displayer slot is created with the DisplayService.

A XV video display widget is wired up to a sigc++ signal slot, using the Glib::Dispatcher to forward calls from the play process thread to the GTK main event loop thread.

When starting playback, the display slot handle created by these preparations is used to create a ~PlayProcess on the ~DummyPlayer interface. Actually

* this uses the provided slot handle to actually //allocate// the display slot via the Display facade. Here, //allocating// means registering and preparing it for output by //one single// ~PlayProcess. For the latter, this allocation yields an actually opened display handle.
* moreover, the ~PlayProcessImpl aquires an TickService instance, which is still trotteling (not calling the periodic callback)
* probably, a real player at this point would initiate a rendering process, so he can fetch the actual output frames periodically.
* on the &quot;upper&quot; side of the ~DummyPlayer facade, an lib::Handle object is created to track and manage this ~PlayProcesImpl instance
The handle is returned to the ~PlaybackController within the GUI, which uses this handle for all further interactions with the Player. The handle is ref counting and has value semantics, so it can be stored away, passed as parameter and so on. All such handles corresponding to one ~PlayProcess form a family; when the last goes out of scope, the ~PlayProcess terminates and deallocates any resources. Conceptually, this corresponds to pushing the &quot;stop&quot; button. Handles can be deliberately disconnected by calling {{{handle.close()}}} &amp;mdash; this has the same effect as deleting a handle (when all are closed or deleted the process ends).

All the other play control operations are simply forwarded via the handle and the ~PlayProcessImpl. For example, &quot;pause&quot; corresponds to setting the tick frequency to 0 (thus temporarily discontinuing the tick callbacks). When allocating the display slot in the course of creating the ~PlayProcessImpl, the latter only accesses the Display facade. It can't access the display or viewer directly, because the GUI lives within an plugin; lower layers can't call directly into GUI functions. Thus, within the Display facade a functor (proxy) is created to represent the output sink. This (proxy) Displayer can be used within the implementation of the perodic callback function. As usual, the implementation of the (proxy) Displayer can be inlined and doesn't create an indirection at runtime. Thus, each frame output call has to pass though two indirections: the function pointer in the Display facade interface, and the Glib::Dispatcher.

!rationale
There can be multiple viewer widgets, to be connected dynamically to multiple play-controllers. (the latter are associated with the timeline(s)). Any playback can require multiple playback processes to work in parallel. The playback controller(s) should not be concerned with managing the play processes, which in turn should neither care for the actual rendering, nor manage the display frequency and synchronisation issues. Moreover, the mentioned parts live in different layers and especially the GUI needs to remain separated from the core. And finally, in case of a problem within one play process, it should be able to unwind automatically, without interfering with other ongoing play processes.
