Detailed Description

Audio attributes for MPEG-1 / MPEG-2 audio.

An MPEG2AudioAttributes object is built by transmitting audio frames from PES payloads. Initially, an AudioAttributes object is invalid.

Constructor & Destructor Documentation

MPEG2AudioAttributes()

ts::MPEG2AudioAttributes::MPEG2AudioAttributes ( )

default

Default constructor.

Member Function Documentation

moreBinaryData()

virtual bool ts::MPEG2AudioAttributes::moreBinaryData ( const uint8_t * addr, size_t size )

overridevirtual

Provides an audio/video binary data to be analyzed by this instance. The type of data (complete PES payload or some type of "frame" or "access unit") depends on the type of audio/video.

Parameters

[in]	addr	Address of data to be analyzed.
[in]	size	Size of data to be analyzed.

Returns

True if the attributes object becomes valid or has new values.

Implements ts::AbstractAudioVideoAttributes.

toString()

virtual UString ts::MPEG2AudioAttributes::toString ( ) const

overridevirtual

Convert to a string object.

Returns

This object, converted as a string.

Implements ts::StringifyInterface.

layer()

int ts::MPEG2AudioAttributes::layer ( ) const

inline

MPEG audio layer.

Returns

The MPEG audio layer (1-3, 0 if unknown).

layerName()

UString ts::MPEG2AudioAttributes::layerName

(

)

const

MPEG audio layer name.

Returns

A string describing the MPEG audio layer.

bitrate()

BitRate ts::MPEG2AudioAttributes::bitrate ( ) const

inline

Bitrate in bits/second.

Returns

The bitrate in bits/second (0 if variable bitrate).

samplingFrequency()

int ts::MPEG2AudioAttributes::samplingFrequency ( ) const

inline

Sampling frequency in Hz.

Returns

The sampling frequency in Hz.

stereoMode()

int ts::MPEG2AudioAttributes::stereoMode ( ) const

inline

Get the mono/stereo mode.

Returns

The mono/stereo mode (see ISO 11172-3).

stereoModeExtension()

int ts::MPEG2AudioAttributes::stereoModeExtension ( ) const

inline

Get the mono/stereo mode extension.

Returns

The mono/stereo mode extension (see ISO 11172-3).

stereoDescription()

UString ts::MPEG2AudioAttributes::stereoDescription

(

)

const

Mono/stereo mode name.

Returns

A string describing the mono/stereo mode .

isValid()

bool ts::AbstractAudioVideoAttributes::isValid ( ) const

inlineinherited

Check if the values in the object are valid.

Returns

True if the values in the object are valid.

invalidate()

void ts::AbstractAudioVideoAttributes::invalidate ( )

inlineinherited

Invalidate the content of this instance. It must be rebuilt using audio/video binary data.

Member Data Documentation

_is_valid

bool ts::AbstractAudioVideoAttributes::_is_valid = false

protectedinherited

A flag which indicates if the content of this object is valid. It is the responsibility of the subclasses to set it.
