◆ FetchKeys() [1/2]

Status shaka::media::WidevineKeySource::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.

◆ FetchKeys() [2/2]

Status shaka::media::WidevineKeySource::FetchKeys	(	const std::vector< uint8_t > &	content_id,
		const std::string &	policy
	)

Fetch keys for CENC from the key server.

Parameters

content_id	the unique id identify the content.
policy	specifies the DRM content rights.

Returns: OK on success, an error status otherwise.

◆ GetCryptoPeriodKey()

Status shaka::media::WidevineKeySource::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.

Implements shaka::media::KeySource.

		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.

◆ GetKey() [2/2]

Status shaka::media::WidevineKeySource::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.

Implements shaka::media::KeySource.
