Member Function Documentation

virtual int TagLib::MP4::Properties::bitrate ( ) const

virtual

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

Implements TagLib::AudioProperties.

virtual int TagLib::MP4::Properties::bitsPerSample ( ) const

virtual

Returns the number of bits per audio sample.

virtual int TagLib::MP4::Properties::channels ( ) const

virtual

Returns the number of audio channels.

Implements TagLib::AudioProperties.

Codec TagLib::MP4::Properties::codec

(

)

const

Returns the codec used in the file.

bool TagLib::MP4::Properties::isEncrypted

(

)

const

Returns whether or not the file is encrypted.

virtual int TagLib::MP4::Properties::length ( ) const

virtual

Returns the length of the file in seconds.

The length is rounded down to the nearest whole second.

Note

This method is just an alias of lengthInSeconds().
