Member Function Documentation

operator()() [1/4]

MediaFactory::PType operator()	(	Asset::Ident &	key,
		const string &	file = ""
	)

Factory method for Media Asset instances.

Depending on the filename given, either a asset::Media object or an "Unknown" placeholder will be provided. If the given Category already contains an "Unkown", we just get the corresponding smart-ptr. Otherwise a new asset::Unknown is created.

Exceptions

error::Invalid

when media file is inaccessible or inappropriate

Returns

an Media smart ptr linked to the internally registered smart ptr created as a side effect of calling the concrete Media subclass ctor.

operator()() [4/4]

lib::P< Clip > operator()

(

Media &

mediaref

)

Factory method for creating a Clip asset based on the given Media asset.

This asset::Clip can be used to create a clip in the session covering the whole length of this media.

Note

creates a dependency between media and new clip

Exceptions

Invalid

if the given media asset is not top-level, but rather part or a multichannel (compound) media
