Field Documentation

IALG_Fxns IVIDDEC_Fxns::ialg

XDAIS algorithm interface.

IALG_Fxns

XDAS_Int32(* IVIDDEC_Fxns::process)(IVIDDEC_Handle handle, XDM_BufDesc *inBufs, XDM_BufDesc *outBufs, IVIDDEC_InArgs *inArgs, IVIDDEC_OutArgs *outArgs)

Basic video 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:

inArgs must not be NULL, and must point to a valid IVIDDEC_InArgs structure.

outArgs must not be NULL, and must point to a valid IVIDDEC_OutArgs 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 inBufs or inArgs. That is, the data and buffers pointed to by these parameters must be treated as read-only.

The buffers in inBufs are owned by the calling application.

Return values:

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

XDAS_Int32(* IVIDDEC_Fxns::control)(IVIDDEC_Handle handle, IVIDDEC_Cmd id, IVIDDEC_DynamicParams *params, IVIDDEC_Status *status)

Control behavior 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 IVIDDEC_DynamicParams structure.

status must not be NULL, and must point to a valid IVIDDEC_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 IVIDDEC_Status::extendedError for more detailed further error conditions.
