Member Function Documentation

virtual AP4_Processor::FragmentHandler* AP4_PiffEncryptingProcessor::CreateFragmentHandler ( AP4_ContainerAtom * ) [virtual]

This method can be overridden by concrete subclasses.

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

Parameters:

track

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

Returns:: A pointer to a fragment handler, or NULL if no handler needs to be created for that fragment.

Reimplemented from AP4_Processor.

virtual AP4_Processor::TrackHandler* AP4_PiffEncryptingProcessor::CreateTrackHandler ( AP4_TrakAtom * ) [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 no handler needs to be created for that track.

Reimplemented from AP4_Processor.

virtual AP4_Result AP4_PiffEncryptingProcessor::Initialize	(	AP4_AtomParent &	top_level,
		AP4_ByteStream &	stream,
		AP4_Processor::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.

Reimplemented from AP4_Processor.
