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().
Implements TagLib::AudioProperties.
| int TagLib::MP4::Properties::lengthInMilliseconds | ( | ) | const |
Returns the length of the file in milliseconds.
- See also:
- lengthInSeconds()
Reimplemented from TagLib::AudioProperties.
| int TagLib::MP4::Properties::lengthInSeconds | ( | ) | const |
Returns the length of the file in seconds. The length is rounded down to the nearest whole second.
- See also:
- lengthInMilliseconds()
Reimplemented from TagLib::AudioProperties.
| virtual int TagLib::MP4::Properties::sampleRate | ( | ) | const [virtual] |
Returns the sample rate in Hz.
Implements TagLib::AudioProperties.
