Field Documentation

IALG_Fxns IIMGENC_Fxns::ialg

XDAIS algorithm interface.

IALG_Fxns

XDAS_Int32(* IIMGENC_Fxns::process)(IIMGENC_Handle handle, XDM_BufDesc *inBufs, XDM_BufDesc *outBufs, IIMGENC_InArgs *inArgs, IIMGENC_OutArgs *outArgs)

Basic image encoding 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 IIMGENC_InArgs structure.

outArgs must not be NULL, and must point to a valid IIMGENC_OutArgs structure.

inBufs must not be NULL, and must point to a valid XDM_BufDesc structure.

outBufs must not be NULL, and must point to a valid XDM_BufDesc structure.

The buffers in inBufs and outBufs are physically contiguous and owned by the calling application.

Postcondition:

The algorithm must not modify the contents of inArgs.

The buffers in inBufs and outBufs are owned by the calling application.

Return values:

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

XDAS_Int32(* IIMGENC_Fxns::control)(IIMGENC_Handle handle, IIMGENC_Cmd id, IIMGENC_DynamicParams *params, IIMGENC_Status *status)

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 IIMGENC_DynamicParams structure.

status must not be NULL, and must point to a valid IIMGENC_Status structure.

Return values:

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