cryptorSubsampleAuxiliaryData

Describes the ranges of protected and unprotected data within a protected sample buffer.

Declaration

var cryptorSubsampleAuxiliaryData: Data? { get set }

Discussion

The value should contain one or more BytesOfClearData/BytesOfProtectedData pairs as appears in the ‘senc’ box (see ISO/IEC 23001-7 section 7.2.2). The BytesOfClearData and the BytesOfProtectedData fields are 32-bit integers. Both are native endian in the Data. This attachment is not present if the CMSampleBuffer contains unprotected content.
