Detailed Description

This class provides an interface to the G711 encoder CMMFHwDevice in order to provide additional configuration information.

The encoder mode

Enumerator	Value	Description
EEncALaw		EncALaw
EEncULaw		EncULaw

TInt

GetVadMode

aVadModeOn

)

[pure virtual]

Gets the current state of the voice activity detection (VAD) mode.

This method can be called at all times - while actively encoding or not.

Parameter	Description
aVadModeOn	On output ETrue=On, EFalse=Off

Returns: KErrNone if successful. KErrNotSupported if this method is not implemented or VAD is not supported by the encoder.

TInt

SetEncoderMode

(

aEncodeMode

)

[pure virtual]

Configures the encoder's encoding format.

This method can be called when decoding is not active - anytime before started or after stopped.

Parameter	Description
aEncodeMode	the encode mode.

Returns: KErrNone if successful. KErrInUse if this method is used when encoding is active. KErrNotSupported if this method is not implemented.

TInt

)

[pure virtual]

Controls voice activity detection (VAD) mode.

This method can be called at all times.

Parameter	Description
aVadModeOn	ETrue=On, EFalse=Off

Returns: KErrNone if successful, KErrNotSupported if this method is not implemented or not supported by the encoder
