Field Documentation

IALG_Fxns ISPHDEC_Fxns::ialg

XDAIS algorithm interface.

XDAS_Int32(* ISPHDEC_Fxns::process)(ISPHDEC_Handle handle, XDM_BufDesc *inBufs, XDM_BufDesc *outBufs, ISPHDEC_InArgs *inArgs, ISPHDEC_OutArgs *outArgs)

Basic speech/voice decoding call.

Parameters:

[in]	handle	Handle to an algorithm instance.
[in]	inBufs	Input buffer descriptors.
[in,out]	outBufs	Output buffer descriptors. The algorithm may modify the output buffer pointers.
[in]	inArgs	Input arguments. This is a required parameter.
[out]	outArgs	Ouput results. This is a required parameter.

Remarks:: process() is a blocking call. When process() returns, the algorithm's processing is complete.

Precondition:: handle must be a valid algorithm instance handle.; inArgs must not be NULL, and must point to a valid ISPHDEC_InArgs structure.; outArgs must not be NULL, and must point to a valid ISPHDEC_OutArgs structure.; inBufs must not be NULL, and must point to a valid XDM_BufDesc structure.; inBufs.buf[0] must not be NULL, and must point to a valid buffer of data that is at least inBufs.bufSizes[0] bytes in length.; outBufs must not be NULL, and must point to a valid XDM_BufDesc structure.; outBufs.buf[0] must not be NULL, and must point to a valid buffer of data that is at least outBufs.bufSizes[0] bytes in length.; The buffers in inBufs and outBufs are physically contiguous and owned by the calling application.

Postcondition:: The algorithm must not modify the contents of inBufs. That is, the data and buffers pointed to by these parameters must be treated as read-only.; The buffers in inBufs and outBufs are owned by the calling application.

Return values:

IALG_EOK	Success.
IALG_EFAIL	Failure. See ISPHDEC_OutArgs::extendedError for more detailed further error conditions.

Control behaviour of an algorithm.

Parameters:

[in]	handle	Handle to an algorithm instance.
[in]	id	Command id. See XDM_CmdId.
[in]	params	Dynamic parameters. This is a required parameter.
[out]	status	Output results. This is a required parameter.

Precondition:: handle must be a valid algorithm instance handle.; params must not be NULL, and must point to a valid ISPHDEC_DynamicParams structure.; status must not be NULL, and must point to a valid ISPHDEC_Status structure.

Postcondition:: The algorithm must not modify the contents of params. That is, the data pointed to by this parameter must be treated as read-only.

Return values:

IALG_EOK	Success.
IALG_EFAIL	Failure. See ISPHDEC_Status::extendedError for more detailed further error conditions.
