Field Documentation

IALG_Fxns IUNIVERSAL_Fxns::ialg

XDAIS algorithm interface.

Basic audio decoding call.

Parameters:

[in]	handle	Handle to an algorithm instance.
[in,out]	inBufs	Input buffer descriptors.
[in,out]	outBufs	Output buffer descriptors.
[in,out]	inOutBufs	Input/Output buffer descriptors.
[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 IUNIVERSAL_InArgs structure.; outArgs must not be NULL, and must point to a valid IUNIVERSAL_OutArgs structure.; inBufs must either be NULL or point to a valid XDM1_BufDesc structure.; outBufs must either be NULL or point to a valid XDM1_BufDesc structure.; inOutBufs must either be NULL or point to a valid XDM1_BufDesc structure.; The buffers in inBufs, outBufs and inOutBufs are physically contiguous and owned by the calling application.

Postcondition:: The algorithm must not modify the contents of inArgs.; The algorithm must not modify the contents of inBufs, with the exception of inBufs.descs[].accessMask. That is, the data and buffers pointed to by these parameters must be treated as read-only.; The algorithm must appropriately set/clear the XDM1_BufDesc::descs[].accessMask field in inBufs, outBufs, and inOutBufs. For example, if the algorithm only read from inBufs.descs[0].buf using the algorithm processor, it could utilize XDM_SETACCESSMODE_READ to update the appropriate accessMask fields. The application may utilize these returned values to appropriately manage cache.; The buffers in inBufs, outBufs, and inOutBufs are owned by the calling application.

Return values:

IUNIVERSAL_EOK	Success.
IUNIVERSAL_EFAIL	General failure. See IUNIVERSAL_Status::extendedError for more detailed further error conditions.
IUNIVERSAL_EUNSUPPORTED	Request is unsupported.

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 IUNIVERSAL_DynamicParams structure.; status must not be NULL, and must point to a valid IUNIVERSAL_Status structure.; If a buffer is provided in the status->data field, it must be physically contiguous and owned by the calling application.

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.; If a buffer was provided in the status->data field, it is owned by the calling application.

Return values:

IUNIVERSAL_EOK	Success.
IUNIVERSAL_EFAIL	General failure. See IUNIVERSAL_Status::extendedError for more detailed further error conditions.
IUNIVERSAL_EUNSUPPORTED	Request is unsupported.
