1. For function-b, the value-b=true block remains as its type is hook, not scythe.
2. I've tried researching on sed but the closest I came to is its function of removing a whole data block from point A to point b i.e. all value-b=true blocks regardless of their type.

mlib_VideoInterpAveY_U8_U8(3MLIB)			    mediaLib Library Functions				 mlib_VideoInterpAveY_U8_U8(3MLIB)

mlib_VideoInterpAveY_U8_U8 - half-pixel interpolation in the Y direction and averaging for reference block SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VideoInterpAveY_U8_U8(mlib_u8 *curr_block, const mlib_u8 *ref_block, mlib_s32 width, mlib_s32 height, mlib_s32 frm_stride, mlib_s32 fld_stride); DESCRIPTION
The mlib_VideoInterpAveY_U8_U8() function performs half-pixel interpolation in the Y direction and averaging for a reference block of data type mlib_u8 and a current block of data type mlib_u8. In this mode, the motion-compensated reference block becomes the current block. Thus, the stride applies to both the input reference block and the current block. PARAMETERS
The function 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. width Width of the blocks. height Height of the blocks. frm_stride Stride, in bytes, between adjacent rows in a frame in both the current block and the reference block. frm_stride must be a multiple of eight. fld_stride Stride, in bytes, between adjacent rows in a field in both the current block and reference block. fld_stride must be a multi- ple of eight. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
