Member Function Documentation

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

Process the input stream into an output stream.

Parameters:
input Reference to the file to process.
output Output stream to which the processed input will be written.
listener Pointer to a listener, or NULL. The listener will be called one or more times before this method returns, with progress information.

virtual AP4_Result AP4_Processor::Initialize ( AP4_AtomParent top_level,
AP4_ByteStream stream,
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 in AP4_MarlinDecryptingProcessor, AP4_OmaDcfDecryptingProcessor, and AP4_OmaDcfEncryptingProcessor.

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_MarlinDecryptingProcessor, AP4_OmaDcfEncryptingProcessor, and AP4_StandardDecryptingProcessor.
