Member Function Documentation

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

pure virtual

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.

virtual Status shaka::media::KeySource::GetCryptoPeriodKey	(	uint32_t	crypto_period_index,
		TrackType	track_type,
		EncryptionKey *	key
	)

pure virtual

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.
track_type	is the type of track 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.

virtual Status shaka::media::KeySource::GetKey	(	TrackType	track_type,
		EncryptionKey *	key
	)

pure virtual

Get encryption key of the specified track type.

Parameters

track_type	is the type of track 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.

virtual Status shaka::media::KeySource::GetKey	(	const std::vector< uint8_t > &	key_id,
		EncryptionKey *	key
	)

pure virtual

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.
