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.
