Field Documentation

IALG_Fxns IVIDENC_Fxns::ialg

XDAIS algorithm interface.

XDAS_Int32(* IVIDENC_Fxns::process)(IVIDENC_Handle handle, XDM_BufDesc *inBufs, XDM_BufDesc *outBufs, IVIDENC_InArgs *inArgs, IVIDENC_OutArgs *outArgs)

Basic video 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:
inArgs must not be NULL, and must point to a valid IVIDENC_InArgs structure.

outArgs must not be NULL, and must point to a valid IVIDENC_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 inArgs.

The buffers in inBufs are owned by the calling application.

Return values:
IALG_EOK Success.
IALG_EFAIL Failure. See IVIDENC_OutArgs::extendedError for more detailed further error conditions.

XDAS_Int32(* IVIDENC_Fxns::control)(IVIDENC_Handle handle, IVIDENC_Cmd id, IVIDENC_DynamicParams *params, IVIDENC_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 IVIDENC_DynamicParams structure.

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