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

Parameters

key_id	is the key identifier. Must be 16 bytes.
key	is the encryption / decryption key. Must be 16 bytes.
pssh_boxes	is the concatenated pssh boxes.
iv	is 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_type	specifies the encrypted media init data type.
init_data	contains 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_index	is the sequence number of the key rotation period for which the key is being retrieved.
stream_label	is the label of stream for which retrieving the key.
key	is 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_label	is the label of stream for which retrieving the key.
key	is 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.

Implements shaka::media::KeySource.

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_id	is the unique identifier for the key being retreived.
key	is 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.
