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 ( )

Destroys this Opus::Properties instance.

◆ Properties() [2/2]

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

Member Function Documentation

◆ bitrate()

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

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

Reimplemented from TagLib::AudioProperties.

◆ channels()

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

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

Returns the length of the file in milliseconds.

Reimplemented from TagLib::AudioProperties.

◆ operator=()

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

◆ 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

Returns the sample rate in Hz.

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