Member Function Documentation

CreateFromKeyAndKeyId()

static std::unique_ptr<PlayReadyKeySource> shaka::media::PlayReadyKeySource::CreateFromKeyAndKeyId ( const std::vector< uint8_t > &  key_id, const std::vector< uint8_t > &  key  )

static

Creates a new PlayReadyKeySource from the given data. Returns null if the strings are invalid. Note: GetKey on the created key source will always return the same key for all track types.

FetchKeys()

Status shaka::media::PlayReadyKeySource::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.

Definition at line 200 of file playready_key_source.cc.

GetCryptoPeriodKey()

Status shaka::media::PlayReadyKeySource::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.

Definition at line 227 of file playready_key_source.cc.

GetKey() [1/2]

Status shaka::media::PlayReadyKeySource::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.

Definition at line 206 of file playready_key_source.cc.

GetKey() [2/2]

Status shaka::media::PlayReadyKeySource::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.
