Detailed Description

Contains all the information that a decryptor needs to decrypt a media sample.

Constructor & Destructor Documentation

shaka::media::DecryptConfig::DecryptConfig	(	const std::vector< uint8_t > &	key_id,
		const std::vector< uint8_t > &	iv,
		const std::vector< SubsampleEntry > &	subsamples
	)

Create a 'cenc' decrypt config.

Parameters

key_id	is the ID that references the decryption key.
iv	is the initialization vector defined by the encryptor.
subsamples	defines the clear and encrypted portions of the sample as described in SubsampleEntry. A decrypted buffer will be equal in size to the sum of the subsample sizes.

shaka::media::DecryptConfig::DecryptConfig	(	const std::vector< uint8_t > &	key_id,
		const std::vector< uint8_t > &	iv,
		const std::vector< SubsampleEntry > &	subsamples,
		FourCC	protection_scheme,
		uint8_t	crypt_byte_block,
		uint8_t	skip_byte_block
	)

Create a general decrypt config with possible pattern-based encryption.

Parameters

key_id	is the ID that references the decryption key.
iv	is the initialization vector defined by the encryptor.
subsamples	defines the clear and encrypted portions of the sample as described in SubsampleEntry. A decrypted buffer will be equal in size to the sum of the subsample sizes.
protection_scheme	specifies the protection scheme: 'cenc', 'cens', 'cbc1', 'cbcs'.
crypt_byte_block	indicates number of encrypted blocks (16-byte) in pattern based encryption, 'cens' and 'cbcs'. Ignored otherwise.
skip_byte_block	indicates number of unencrypted blocks (16-byte) in pattern based encryption, 'cens' and 'cbcs'. Ignored otherwise.

void shaka::media::DecryptConfig::AddSubsample	(	uint16_t	clear_bytes,
		uint32_t	cipher_bytes
	)

inline

Parameters

clear_bytes	is the size of clear bytes in the subsample to be added.
cipher_bytes	is the size of cipher bytes in the subsample to be added.
