Detailed Description

As such, it is a virtual (non destructive) cut or edit of the source material and can be placed into the EDL to be rendered into the ouput. The actual media type of a clip will be derived at runtime by resolving this reference to the underlying Asset.

Todo:

define how to denote Time positions /lengths. This is tricky, because it depends on the actual media type, and we want to encapsulate all these details as much as possible.

Definition at line 57 of file clip.hpp.

Constructor & Destructor Documentation

mobject::session::Clip::Clip	(	const asset::Clip &	clipDef,
		const Media &	mediaDef
	)			[protected]

Initially, this clip will cover the whole source media length.

Definition at line 37 of file clip.cpp.

      : start_(0),
        mediaDef_(mediaDef),
        clipDef_(clipDef)
    {
      setupLength();
    }

Member Function Documentation

bool mobject::session::Clip::isValid

(

)

const [virtual]

Length definition is consitent, underlying media def is accessible etc.

Implements mobject::MObject.

Definition at line 51 of file clip.cpp.

    {
      TODO ("check consistency of clip length def, implies accessing the underlying media def");
      return length > 0;
    }

Member Data Documentation

const Media& mobject::session::Clip::mediaDef_ [protected]

Todo:

using a mere ref here is against the scheme and only done as temporal solution, until we work out how to handle multichannel clips. It should be a smart pointer of some kind and the unlink() function of the asset should take it into account when breaking circular references.

Definition at line 70 of file clip.hpp.
