Description

Each of these functions performs half-pixel interpolation in the X and Y directions for a reference block of data type mlib_u8 and a current block of data type mlib_s16. In this mode, the output of this function must be added to the IDCT output to reconstruct the block in the current frame. Thus, the stride applies only to the input reference block.

Parameters

Each of the functions takes the following arguments:

mc_block

Pointer to the motion-compensated reference block. mc_block must be 8-byte aligned.

ref_block

Pointer to the reference block.

frm_stride

Stride, in bytes, between adjacent rows in a frame in the reference block. frm_stride must be a multiple of eight.

fld_stride

Stride, in bytes, between adjacent rows in a field in the reference block. fld_stride must be a multiple of eight.

Return Values

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
