Creates a new FixedKeySource from the given data. Returns null if the strings are invalid.

Parameters
key_idis the key identifier. Must be 16 bytes.
keyis the encryption / decryption key. Must be 16 bytes.
pssh_boxesis the concatenated pssh boxes.
ivis the initialization vector. If not specified, a randomly generated IV with the default length will be used. Note: GetKey on the created key source will always return the same key for all track types.

Status shaka::media::FixedKeySource::FetchKeys ( EmeInitDataType  init_data_type,
const std::vector< uint8_t > &  init_data 
)
overridevirtual

Fetch keys based on the specified encrypted media init data.

Parameters
init_data_typespecifies the encrypted media init data type.
init_datacontains the init data.
Returns
OK on success, an error status otherwise.

Implements shaka::media::KeySource.

Status shaka::media::FixedKeySource::GetCryptoPeriodKey ( uint32_t  crypto_period_index,
const std::string &  stream_label,
EncryptionKey key 
)
overridevirtual

Get encryption key of the specified track type at the specified index.

Parameters
crypto_period_indexis the sequence number of the key rotation period for which the key is being retrieved.
stream_labelis the label of stream for which retrieving the key.
keyis a pointer to the EncryptionKey which will hold the retrieved key. Owner retains ownership, and may not be NULL.
Returns
OK on success, an error status otherwise.

Status shaka::media::FixedKeySource::GetKey ( const std::string &  stream_label,
EncryptionKey key 
)
overridevirtual

Get encryption key of the specified stream label.

Parameters
stream_labelis the label of stream for which retrieving the key.
keyis a pointer to the EncryptionKey which will hold the retrieved key. Owner retains ownership, and may not be NULL.
Returns
OK on success, an error status otherwise.

Status shaka::media::FixedKeySource::GetKey ( const std::vector< uint8_t > &  key_id,
EncryptionKey key 
)
overridevirtual

Get the encryption key specified by the CENC key ID.

Parameters
key_idis the unique identifier for the key being retreived.
keyis a pointer to the EncryptionKey which will hold the retrieved key. Owner retains ownership, and may not be NULL.
Returns
OK on success, or an error status otherwise.
