Member Function Documentation
[explicit] QAudioBufferOutput::QAudioBufferOutput(QObject *parent = nullptr)
Constructs a new QAudioBufferOutput object with parent.
The audio format of output audio buffers will depend on the source media file and the inner audio decoder in QMediaPlayer.
[explicit] QAudioBufferOutput::QAudioBufferOutput(const QAudioFormat &format, QObject *parent = nullptr)
Constructs a new QAudioBufferOutput object with audio format and parent.
If the specified format is valid, it will be the format of output audio buffers. Otherwise, the format of output audio buffers will depend on the source media file and the inner audio decoder in QMediaPlayer.
[override virtual noexcept] QAudioBufferOutput::~QAudioBufferOutput()
Destroys the audio buffer output object.
[signal] void QAudioBufferOutput::audioBufferReceived(const QAudioBuffer &buffer)
Signals that a new audio buffer has been received from QMediaPlayer.
QAudioFormat QAudioBufferOutput::format() const
Gets the audio format specified in the constructor.
If the format is valid, it specifies the format of output oudio buffers.
