Member Data Documentation

uint32_t PP_EncryptedBlockInfo::data_offset

Size in bytes of data to be discarded before applying the decryption.

Definition at line 139 of file pp_content_decryptor_samsung.h.

uint32_t PP_EncryptedBlockInfo::data_size

Size in bytes of data to be decrypted (data_offset included).

Definition at line 135 of file pp_content_decryptor_samsung.h.

uint8_t PP_EncryptedBlockInfo::iv[16]

Initialization vector of the block to be decrypted.

Definition at line 154 of file pp_content_decryptor_samsung.h.

uint32_t PP_EncryptedBlockInfo::iv_size

Definition at line 155 of file pp_content_decryptor_samsung.h.

uint8_t PP_EncryptedBlockInfo::key_id[64]

Key ID of the block to be decrypted.

TODO(xhwang): For WebM the key ID can be as large as 2048 bytes in theory. But it's not used in current implementations. If we really need to support it, we should move key ID out as a separate parameter, e.g. as a PP_Var, or make the whole PP_EncryptedBlockInfo as a PP_Resource.

uint32_t PP_EncryptedBlockInfo::key_id_size

Definition at line 150 of file pp_content_decryptor_samsung.h.

uint32_t PP_EncryptedBlockInfo::num_subsamples

Definition at line 160 of file pp_content_decryptor_samsung.h.

uint32_t PP_EncryptedBlockInfo::padding

4-byte padding to make the size of PP_EncryptedBlockInfo a multiple of 8 bytes. The value of this field should not be used.

Definition at line 165 of file pp_content_decryptor_samsung.h.

struct PP_DecryptSubsampleDescription PP_EncryptedBlockInfo::subsamples[16]

Subsample information of the block to be decrypted.
