mlib_status mlib_VideoCopyRefAve_U8_U8_8x8(mlib_u8 *curr_block,
    const mlib_u8 *ref_block, mlib_s32 stride);

mlib_status mlib_VideoCopyRefAve_U8_U8_8x4(mlib_u8 *curr_block,
    const mlib_u8 *ref_block, mlib_s32 stride);

 

DESCRIPTION

Each of these functions copies and averages a block from the reference block to the current block. The stride applies to both the input reference block and the current block.  

PARAMETERS

Each of the functions takes the following arguments:

curr_block

Pointer to the current block. curr_block must be 8-byte aligned.

ref_block

Pointer to the reference block.

stride

Stride, in bytes, between adjacent rows in both the current block and the reference block. stride must be a multiple of eight.

 

RETURN VALUES

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