Function Documentation

int sceAtracAddStreamData	(	int	atracID,
		unsigned int	bytesToAdd
	)

Parameters:

atracID

- the atrac ID

Parameters:

bytesToAdd

- Number of bytes read into location given by sceAtracGetStreamDataInfo().

Returns:

< 0 on error, otherwise 0

int sceAtracDecodeData	(	int	atracID,
		u16 *	outSamples,
		int *	outN,
		int *	outEnd,
		int *	outRemainFrame
	)

Decode a frame of data.

Parameters:

	atracID	- the atrac ID
	outSamples	- pointer to a buffer that receives the decoded data of the current frame
	outN	- pointer to a integer that receives the number of audio samples of the decoded frame
	outEnd	- pointer to a integer that receives a boolean value indicating if the decoded frame is the last one
	outRemainFrame	- pointer to a integer that receives either -1 if all at3 data is already on memory, or the remaining (not decoded yet) frames at memory if not all at3 data is on memory

Returns:

< 0 on error, otherwise 0

int sceAtracGetBitrate	(	int	atracID,
		int *	outBitrate
	)

Gets the bitrate.

Parameters:

	atracID	- the atracID
	outBitrate	- pointer to a integer that receives the bitrate in kbps

Returns:

< 0 on error, otherwise 0

int sceAtracGetMaxSample	(	int	atracID,
		int *	outMax
	)

Gets the maximum number of samples of the atrac3 stream.

Parameters:

	atracID	- the atrac ID
	outMax	- pointer to a integer that receives the maximum number of samples.

Returns:

< 0 on error, otherwise 0

int sceAtracGetNextSample	(	int	atracID,
		int *	outN
	)

Gets the number of samples of the next frame to be decoded.

Parameters:

	atracID	- the atrac ID
	outN	- pointer to receives the number of samples of the next frame.

Returns:

< 0 on error, otherwise 0

int sceAtracGetRemainFrame	(	int	atracID,
		int *	outRemainFrame
	)

Gets the remaining (not decoded) number of frames.

Parameters:

	atracID	- the atrac ID
	outRemainFrame	- pointer to a integer that receives either -1 if all at3 data is already on memory, or the remaining (not decoded yet) frames at memory if not all at3 data is on memory

Returns:

< 0 on error, otherwise 0

int sceAtracGetStreamDataInfo	(	int	atracID,
		u8 **	writePointer,
		u32 *	availableBytes,
		u32 *	readOffset
	)

Parameters:

atracID

- the atrac ID

Parameters:

	writePointer	- Pointer to where to read the atrac data
	availableBytes	- Number of bytes available at the writePointer location
	readOffset	- Offset where to seek into the atrac file before reading

Returns:

< 0 on error, otherwise 0

int sceAtracReleaseAtracID

(

int

atracID

)

It releases an atrac ID.

Parameters:

atracID

- the atrac ID to release

Returns:

< 0 on error

int sceAtracSetDataAndGetID	(	void *	buf,
		SceSize	bufsize
	)

Creates a new Atrac ID from the specified data.

Parameters:

	buf	- the buffer holding the atrac3 data, including the RIFF/WAVE header.
	bufsize	- the size of the buffer pointed by buf

Returns:

the new atrac ID, or < 0 on error

int sceAtracSetLoopNum	(	int	atracID,
		int	nloops
	)

Sets the number of loops for this atrac ID.

Parameters:

	atracID	- the atracID
	nloops	- the number of loops to set

Returns:

< 0 on error, otherwise 0
