How to get length of a song using Qt 5.1?
audio, c++, qt, qt5, qtmultimedia
Solution
You seem to be looking for the `duration` property.
This would be the QML solution:
duration : int
This property holds the duration of the media in milliseconds.
If the media doesn't have a fixed duration (a live stream for example) this will be 0.
This would be the C++ solution:
qint64 QAudioBuffer::duration() const
Returns the duration of audio in this buffer, in microseconds.
This depends on the /l format(), and the frameCount().
Problem
How can I get the length of a song in Qt 5.1 API? I think I can read it using `Length` metadata but I'm not sure if this metadata will be available for all audio files.
