Detailed Description

Defines the base Descriptor object as defined in ISO 14496-1:2004 Systems section 7.2.2.2. All descriptors inherit from either BaseDescriptor.

Member Function Documentation

ComputeSize()

size_t shaka::media::BaseDescriptor::ComputeSize

(

)

Compute the size of this descriptor. It will also update descriptor size.

Returns

The size of result descriptor including child descriptors.

Definition at line 110 of file es_descriptor.cc.

data_size()

size_t shaka::media::BaseDescriptor::data_size ( ) const

inlineprotected

Returns

descriptor data size without header in bytes.

Definition at line 69 of file es_descriptor.h.

Parse()

bool shaka::media::BaseDescriptor::Parse

(

const std::vector< uint8_t > &

data

)

Parse the descriptor from input data.

Parameters

data	contains the descriptor data.

Definition at line 83 of file es_descriptor.cc.

Read()

bool shaka::media::BaseDescriptor::Read

(

BitReader *

reader

)

Read the descriptor.

Parameters

reader

points to a BitReader object.

Definition at line 88 of file es_descriptor.cc.

Write()

void shaka::media::BaseDescriptor::Write

(

BufferWriter *

writer

)

Write the descriptor to buffer. This function calls ComputeSize internally to compute and update descriptor size.

Parameters

writer

points to a BufferWriter object which wraps the buffer for writing.

Definition at line 100 of file es_descriptor.cc.

WriteHeader()

void shaka::media::BaseDescriptor::WriteHeader ( BufferWriter *  writer )

protected

Write descriptor header.

Definition at line 115 of file es_descriptor.cc.
