Member Enumeration Documentation

◆ SampleEncryptionFlags

enum shaka::media::mp4::SampleEncryption::SampleEncryptionFlags

Definition at line 109 of file box_definitions.h.

Member Function Documentation

◆ BoxType()

FourCC shaka::media::mp4::SampleEncryption::BoxType ( ) const

overridevirtual

Returns: box type.

Implements shaka::media::mp4::Box.

Definition at line 327 of file box_definitions.cc.

◆ ParseFromSampleEncryptionData()

bool shaka::media::mp4::SampleEncryption::ParseFromSampleEncryptionData	(	uint8_t	l_iv_size,
		std::vector< SampleEncryptionEntry > *	l_sample_encryption_entries
	)		const

Parse from sample_encryption_data.

Parameters

	iv_size	specifies the size of initialization vector.
[out]	sample_encryption_entries	receives parsed sample encryption entries.

Returns: true on success, false otherwise.

Definition at line 382 of file box_definitions.cc.

Member Data Documentation

◆ iv_size

uint8_t shaka::media::mp4::SampleEncryption::iv_size = kInvalidIvSize

Definition at line 127 of file box_definitions.h.

◆ kInvalidIvSize

const uint8_t shaka::media::mp4::SampleEncryption::kInvalidIvSize = 1

static

Definition at line 107 of file box_definitions.h.

◆ sample_encryption_data

std::vector<uint8_t> shaka::media::mp4::SampleEncryption::sample_encryption_data

We may not know iv_size before reading this box. In this case, we will store sample encryption data for parsing later when iv_size is known.

Definition at line 125 of file box_definitions.h.

◆ sample_encryption_entries

std::vector<SampleEncryptionEntry> shaka::media::mp4::SampleEncryption::sample_encryption_entries

Definition at line 128 of file box_definitions.h.
