protected: inline MMMFAudioInput();

Description

Protected constructor.

static inline MMMFAudioInput *NewAudioInputL(TUid aImplementationUid, const TDesC8 &aInitData);

Description

Allocates and constructs an audio input object.

Calls MDataSource::NewSourceL().

Parameters

TUid aImplementationUid The Implementation UID. const TDesC8 &aInitData The initialisation data.

Return value

MMMFAudioInput * A new audio input object.

virtual CMMFDevSound &SoundDevice()=0;

Description

Returns the sound device.

Return value

CMMFDevSound & A reference to a CMMFDevSound objector. Accessor function exposing public CMMFDevsound methods.

virtual TInt BytesPlayed()=0;

Description

Returns the number of bytes played.

Return value

TInt The number of bytes played. If 16-bit divide this number returned by 2 to get word length.

virtual void HWFillBufferL(CMMFBuffer *aBuffer, MDataSink *aConsumer)=0;

Description

Gets audio from hardware device abstracted MMFDevsound (not used).

Parameters

CMMFBuffer *aBuffer The data to read in from a Hardware Device MDataSink *aConsumer The MDataSink consuming the data contained in aBuffer.
