java.lang.Object

org.mp4parser.boxes.iso23001.part7.CencSampleAuxiliaryDataFormat

public class CencSampleAuxiliaryDataFormat
extends Object

Each encrypted sample in a protected track shall have an Initialization Vector associated with it. Further, each encrypted sample in protected AVC video tracks shall conform to ISO/IEC 14496-10 and ISO/IEC 14496-15 and shall use the subsample encryption scheme specified in 9.6.2, which requires subsample encryption data. Both initialization vectors and subsample encryption data are provided as Sample Auxiliary Information with aux_info_type equal to ‘cenc’ and aux_info_type_parameter equal to 0. For tracks protected using the 'cenc' scheme, the default value for aux_info_type is equal to 'cenc' and the default value for the aux_info_type_parameter is 0 so content may be created omitting these optional fields. Storage of sample auxiliary information shall conform to ISO/IEC 14496-12.
This class can also be used for PIFF as it has been derived from the PIFF spec.
