Description:
Helper class to read ISO 15444-12 files (HEIF/HEIC files, among others).
See users of me (clients).
ISOBMFF is the base-format used for a whole bunch of concrete file formats:
QuickTime etc.
Apple recently changed their default camera format to HEIC.
Concrete formats must be parsed by concrete readers.
Use:
Define your reader as a client to this reader, and let it process boxes.
See HEICReader for a concrete example.
This is in an experimental state and not yet finished.
The protocol may change.
