Synopsis
XDAS_Int32 (*process)(IVIDENC1_Handle handle,
IVIDEO1_BufDescIn *inBufs, XDM_BufDesc *outBufs,
IVIDENC1_InArgs *inargs, IVIDENC1_OutArgs *outargs);
║ Arguments
IVIDENC1_Handle handle; /* algorithm instance handle */
IVIDEO1_BufDescIn *inBufs; /* algorithm input buffer
descriptor */
XDM_BufDesc *outBufs; /* algorithm output buffer
descriptor */
IVIDENC1_InArgs *inargs /* algorithm runtime input
arguments */
IVIDENC1_OutArgs *outargs /* algorithm runtime output
arguments */
║ Return Value
IALG_EOK; /* status indicating success */
IALG_EFAIL; /* status indicating failure */
║ Description
This function does the basic encoding/decoding. The first argument to
process()
is a handle to an algorithm instance.
The second argument is a pointer to the input buffer descriptor data
structure. (see
IVIDEO1_BufDescIn
data structure for details).
The third argument is a pointer to the output buffer descriptor data
structure. (see
XDM_BufDesc
data structure for details).
The fourth argument is a pointer to the
IVIDENC1_InArgs
data structure
that defines the run-time input arguments for an algorithm instance object.
The last argument is a pointer to the
IVIDENC1_OutArgs
data structure
that defines the run-time output arguments for an algorithm instance object.
Note :
‰ If the fourth and the fifth arguments point to the base data structure
of
InArgs
and
OutArgs,
then the basic parameters are used.
‰ If the fourth and the fifth arguments point to the extended data
structure of
InArgs
and
OutArgs,
then the extended parameters
are used.
