MFSampleEncryptionProtectionScheme enumeration (mfapi.h)

Specifies the supported protection schemes for encrypted samples.

Syntax

typedef enum _MFSampleEncryptionProtectionScheme {
  MF_SAMPLE_ENCRYPTION_PROTECTION_SCHEME_NONE = 0,
  MF_SAMPLE_ENCRYPTION_PROTECTION_SCHEME_AES_CTR = 1,
  MF_SAMPLE_ENCRYPTION_PROTECTION_SCHEME_AES_CBC = 2
} MFSampleEncryptionProtectionScheme;

Constants

MF_SAMPLE_ENCRYPTION_PROTECTION_SCHEME_NONE Value: 0 No encryption scheme.
MF_SAMPLE_ENCRYPTION_PROTECTION_SCHEME_AES_CTR Value: 1 The encryption scheme is AES counter mode (CTR).
MF_SAMPLE_ENCRYPTION_PROTECTION_SCHEME_AES_CBC Value: 2 The encryption scheme is Cipher Block Chaining (CBC).

Remarks

The encryption scheme for a sample is specified using the MFSampleExtension_Encryption_ProtectionScheme attribute.
