getID()

virtual const ID<Media>& getID ( ) const

Returns

ID of kind Media

Reimplemented from Asset.

howtoProc()

Media::PProcPatt howtoProc

(

)

const

Service Access Point for getting a processing template describing how to build the render nodes network necessary for this Media or Clip.

This includes Codecs and postprocessing (stretching, deinterlacing...)

Definition at line 111 of file media.cpp.

createClip()

Media::PClip createClip

(

)

Service Access Point for creating a Clip entity usable within the Session from a given Media or Clip Asset.

As a sideeffect, a corresponding asset::Clip is created as well if necessary. It is OK to use and throw away the returned Clip-MO, because it can be regenerated from the corresponding asset::Clip

Returns

a Placement smart ptr owning the new Clip MObject

Definition at line 75 of file media.cpp.

getLength()

Duration getLength ( ) const

virtual

Returns

the overall length of the media represented by this asset

Definition at line 122 of file media.cpp.

References Media::create.

getClipAsset()

Media::PClipAsset getClipAsset ( )

protectedvirtual

get or create the correct asset::Clip corresponding to this media

used to either create an asset::Clip denoting the whole media, or to get the right reference to some already existing asset::Clip, especially when this media is part of a compound (multichannel) media.

Reimplemented in Clip.

predicate to decide if this asset::Media is part of a compound (multichannel) media.

Returns

pointer to parent, or null
