mlib_status mlib_VideoAddBlock_U8_S16(mlib_u8 *curr_block, 
     const mlib_s16 *mc_block, mlib_s32 stride);

Description

The mlib_VideoAddBlock_U8_S16() function performs additions of prediction and coefficient data. In other words, the function adds a motion-compensated 8x8 block to the current block. The stride applies to the current block.

Parameters

The function takes the following arguments:

curr_block

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

mc_block

Pointer to an 8x8 motion-compensated block (prediction data). mc_block must be 8-byte aligned.

stride

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

Return Values

The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
