Member Function Documentation

AP4_Result AP4_Processor::Process	(	AP4_ByteStream &	input,
		AP4_ByteStream &	output,
		ProgressListener *	listener = NULL,
		AP4_AtomFactory &	atom_factory = AP4_DefaultAtomFactory::Instance
	)

virtual AP4_Result AP4_Processor::Initialize	(	AP4_AtomParent &	top_level,
		ProgressListener *	listener = NULL
	)			[virtual]

This method can be overridden by concrete subclasses.

It is called just after the input stream has been parsed into an atom tree, before the processing of the tracks.

Parameters:

top_level

Container atom containing all the atoms parsed from the input stream. Note that this atom does not actually exist in the file; it is a synthetised container created for the purpose of holding together all the input's top-level atoms.

virtual AP4_Result AP4_Processor::Finalize	(	AP4_AtomParent &	top_level,
		ProgressListener *	listener = NULL
	)			[virtual]

This method can be overridden by concrete subclasses.

It is called just after the tracks have been processed.

virtual TrackHandler* AP4_Processor::CreateTrackHandler

(

AP4_TrakAtom *

trak

)

[virtual]

This method can be overridden by concrete subclasses.

It is called once for each track in the input file.

Parameters:

track

Pointer to the track for which a handler should be created.

Returns:

A pointer to a track handler, or NULL if not handler needs to be created for that track.

Reimplemented in AP4_IsmaEncryptingProcessor, AP4_OmaDcfEncryptingProcessor, and AP4_StandardDecryptingProcessor.
