And, last but not least, doing all actual allocations is the job of the backend. Exceptions being long-lived objects, like the Session or the EDL, which are created once and don't bear the danger of causing memory pressure. Besides that, the ProcLayer code shouldn't issue "new" and "delete", rather it should use some central [[Factories]] for all allocation and freeing, so we can redirect these calls down to the backend, which may use pooling or special placement allocators or the like. The rationale is, for modern hardware/architectures, care has to be taken with heap allocations, esp. with many small objects and irregular usage patterns.

!Compound Media
|
||||
[>img[Outline of the Build Process|uml/fig131333.png]]
|
||||
Basically, each [[media asset|MediaAsset]] is considered to be a compound of several elementary media (tracks), possibly of various different media kinds. Adding support for placeholders (''proxy clips'') at some point in future will add still more complexity (because then there will be even dependencies between some of these elementary media). To handle, edit and render compound media, we need to impose some structural limitations. But anyhow, we try to configure as much as possible already at the "asset level" and make the rest of the proc layer behave just according to the configuration given with each asset.
|
||||
|
||||
So, when creating a clip out of such a compound media asset, the clip has to be a compound of elementary clips mirroring the given media asset's structure. Besides, it should be possible to //detach// and //attach// elementary clips from a compound clip. On the other hand, the [[Fixture]] created from the current state of the [[EDL]] is explicit to a great extent. So, in the Fixture we deal only with elementary clips placed to absolute positions, and thus the builder will see only simple non-compound clips and translate them into the corresponding source reading nodes.

<pre>What is the Role of the asset::Clip and how exactly are Assets and (Clip)-MObjects related?
|
||||
|
||||
First of all: ~MObjects are the dynamic/editing/manipulation view, while Assets are the static/bookkeeping/searching/information view of the same entities. Thus, the asset::Clip contains the general configuration, the ref to the media and descriptive properties, while all parameters being "manipulated" belong to the session::Clip (MObject). Besides that, the practical purpose of asset::Clip is that you can save and remember some selection as a Clip (Asset), maybe even attach some informations or markup to it, and later be able to (re)create a editable representation in the Session (the GUI could implement this by allowing to drag from the asset::Clip GUI representation to the timeline window)

!!multiplicity and const-ness

The link between ~MObject and Asset should be {{{const}}} in both directions (to enforce the separation of concerns). So the Asset can't //edit// the clip and the clip can't change the media parameters.

The relation logical relation, but it is not strictly 1:1 because typical media are [[multichannel|MultichannelMedia]]. Even if the media is compound, there is //only one asset::Clip//, because in the logical view we have only one "clip-thing". On the other hand, in the Session/EDL, we have a compound clip ~MObject comprised of several elementary clip objects, each of which will refer to its own sub-media (channel) within the compound media (and don't forget, this structure can be tree-like)
|
||||
The link between ~MObject and Asset should be {{{const}}}, so the clip can't change the media parameters. Because of separation of concerns, it would be desirable that the Asset can't //edit// the clip either (meaning {{{const}}} in the opposite direction as well). But unfortunately the asset::Clip is in power to delete the clip-MO and, moreover, handles out a smart ptr ([[Placement]]) referring to the clip-MO, which can (and should) be used to place the clip-MO within the EDL and to manipulate it consequently...
