void CVorbisDecoder::PacketInL

(

ogg_packet

aPacket

)

This method takes an oggpacket as an input and submits into the vorbis synthesis block which is owned by the tremor. This method can be repeatedly called by the client during initialisation until 3 packets have been found, at which point the vorbis libraries are initialised.

Parameters:

aPacket

An ogg_packet. Leaves with KErrNotSupported when the data does not belong to the vorbis stream, KErrCorrupt if header is corrupted and any of the system wide error codes.

void CVorbisDecoder::PcmOutL

(

TDes8 &

aBuf

)

This method decodes the oggpacket submitted during PacketInL() into pcmdata and fills the destination buffer.

Parameters:

aBuf

The buffer in which the pcmdata is submitted.

Leaves with KErrNotSupported when the data does not belong to the vorbis stream, KErrCorrupt if header is corrupted and any of the system wide error codes.

void CVorbisDecoder::DecoderL	(	const CMMFDataBuffer &	aBuf,
		TDes8 &	aDstBuf
	)

This method extracts all ogg pages and packets from source buffer and sends each packet to PacketInL() for decoding. pcmdata and fills the destination buffer.

Parameters:

	aBuf	The source buffer contains encoded data.
	aDstBuf	The destination buffer in which the pcmdata is submitted.

Leaves with any system wide error code.
