Member Function Documentation

◆ FetchKeys()

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

Implemented in shaka::media::WidevineKeySource, shaka::media::RawKeySource, and shaka::media::PlayReadyKeySource.

◆ GetCryptoPeriodKey()

virtual Status shaka::media::KeySource::GetCryptoPeriodKey ( uint32_t  crypto_period_index,
int32_t  crypto_period_duration_in_seconds,
const std::string &  stream_label,
EncryptionKey key 
)
pure virtual

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.
crypto_period_duration_in_secondsis the duration of the crypto period in seconds.
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.

Implemented in shaka::media::WidevineKeySource, shaka::media::RawKeySource, and shaka::media::PlayReadyKeySource.

◆ GetKey() [1/2]

virtual Status shaka::media::KeySource::GetKey ( const std::string &  stream_label,
EncryptionKey key 
)
pure virtual

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.

Implemented in shaka::media::WidevineKeySource, shaka::media::RawKeySource, and shaka::media::PlayReadyKeySource.

◆ GetKey() [2/2]

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_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.

Implemented in shaka::media::WidevineKeySource, shaka::media::RawKeySource, and shaka::media::PlayReadyKeySource.
