Public Attributes | |
| uint32_t | encryption_type |
Encryption type, refer to VA_ENCRYPTION_TYPE_FULLSAMPLE_CTR, VA_ENCRYPTION_TYPE_FULLSAMPLE_CBC, VA_ENCRYPTION_TYPE_SUBSAMPLE_CTR, or VA_ENCRYPTION_TYPE_SUBSAMPLE_CBC. | |
| uint32_t | num_segments |
| The number of sengments. | |
| VAEncryptionSegmentInfo * | segment_info |
| Pointer of segments. | |
| uint32_t | status_report_index |
| The status report index reserved for CENC fullsample workload. The related structures and definitions are vendor specific. | |
| uint32_t | size_of_length |
| CENC counter length. | |
| uint8_t | wrapped_decrypt_blob [64] |
Wrapped decrypt blob (Snd)kb, valid size is specified by key_blob_size. | |
| uint8_t | wrapped_encrypt_blob [64] |
Wrapped Key blob info (Sne)kb, valid size is specified by key_blob_size. | |
| uint32_t | key_blob_size |
key blob size It could be VA_PC_BLOCK_SIZE_128, VA_PC_BLOCK_SIZE_192, or VA_PC_BLOCK_SIZE_256 | |
| uint32_t | blocks_stripe_encrypted |
| Indicates the number of 16-byte BLOCKS that are encrypted in any given encrypted region of segments. If this value is zero: More... | |
| uint32_t | blocks_stripe_clear |
| Indicates the number of 16-byte BLOCKS that are clear in any given encrypted region of segments, as defined by the CENS and CBCS schemes in the common encryption spec. If this value is zero, all bytes in encrypted region of segments are encrypted, i.e. the CENC or CBC1 scheme is being used. | |
| uint32_t | va_reserved [VA_PADDING_MEDIUM] |
| Reserved bytes for future use, must be zero. | |
Encryption parameters buffer for VAEncryptionParameterBufferType.
| uint32_t VAEncryptionParameters::blocks_stripe_encrypted |
