Detailed Description

An implementation of audio property reading for Ogg Opus.

This reads the data from an Ogg Opus stream found in the AudioProperties API.

Constructor & Destructor Documentation

Properties() [1/2]

TagLib::Ogg::Opus::Properties::Properties	(	File *	file,
		ReadStyle	style = Average
	)

Create an instance of Opus::Properties with the data read from the Opus::File file.

~Properties()

TagLib::Ogg::Opus::Properties::~Properties ( )

override

Destroys this Opus::Properties instance.

Properties() [2/2]

TagLib::Ogg::Opus::Properties::Properties ( const Properties &  )

delete

Member Function Documentation

bitrate()

int TagLib::Ogg::Opus::Properties::bitrate ( ) const

overridevirtual

Returns the average bit rate of the file in kb/s.

Reimplemented from TagLib::AudioProperties.

channels()

int TagLib::Ogg::Opus::Properties::channels ( ) const

overridevirtual

Returns the number of audio channels.

Implements TagLib::AudioProperties.

inputSampleRate()

int TagLib::Ogg::Opus::Properties::inputSampleRate

(

)

const

The Opus codec supports decoding at multiple sample rates, there is no single sample rate of the encoded stream. This returns the sample rate of the original audio stream.

lengthInMilliseconds()

int TagLib::Ogg::Opus::Properties::lengthInMilliseconds ( ) const

overridevirtual

Returns the length of the file in milliseconds.

See also

lengthInSeconds()

Reimplemented from TagLib::AudioProperties.

operator=()

Properties & TagLib::Ogg::Opus::Properties::operator= ( const Properties &  )

delete

opusVersion()

int TagLib::Ogg::Opus::Properties::opusVersion

(

)

const

Returns the Opus version, in the range 0...255.

sampleRate()

int TagLib::Ogg::Opus::Properties::sampleRate ( ) const

overridevirtual

Returns the sample rate in Hz.

Note

Always returns 48000, because Opus can decode any stream at a sample rate of 8, 12, 16, 24, or 48 kHz,

Reimplemented from TagLib::AudioProperties.
