NAME

       mlib_VideoDCT8x8_S16_U8_NA - forward Discrete Cosine Transform (DCT)

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoDCT8x8_S16_U8_NA(mlib_s16 coeffs[64],
	    const mlib_u8 *block, mlib_s32 stride);

DESCRIPTION

       The  mlib_VideoDCT8x8_S16_U8_NA()  function  computes the forward DCT for the destination DCT coefficients of data type mlib_s16 and source
       block of data type mlib_u8. The stride applies to the block that is part of the frame currently being encoded.

       This function requires no special address alignment.

       This function can be used in JPEG with 8-bit precision, or in MPEG for the intra mode.

PARAMETERS

       The function takes the following arguments:

       coeffs	 Pointer to the destination DCT coefficients.

       block	 Pointer to an 8x8 block in the current frame.

       stride	 Stride in bytes between adjacent rows in the block.

RETURN VALUES

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

NAME

       mlib_VideoDCT8x8_S16_S16_B10_NA, mlib_VideoDCT8x8_S16_S16_NA - forward Discrete Cosine Transform (DCT)

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_VideoDCT8x8_S16_S16_B10_NA(
	    mlib_s16 coeffs[64], const mlib_s16 block[64]);

       mlib_status mlib_VideoDCT8x8_S16_S16_NA(
	    mlib_s16 coeffs[64], const mlib_s16 block[64]);

DESCRIPTION

       The  mlib_VideoDCT8x8_S16_S16_B10_NA()  function  computes the forward DCT for the destination DCT coefficients of data type mlib_s16 and a
       source block of data type mlib_s16. The input to the DCT routine is the difference between the current block and the reference  block.  The
       difference pixel can occupy nine bits and is represented as a 16-bit datum.

       This function requires no special address alignment.

       Since  mediaLib 2.5, mlib_VideoDCT8x8_S16_S16_NA() has been renamed to mlib_VideoDCT8x8_S16_S16_B10_NA(). Now mlib_VideoDCT8x8_S16_S16_NA()
       is an alias of mlib_VideoDCT8x8_S16_S16_B10_NA().

PARAMETERS

       The function takes the following arguments:

       coeffs	 Pointer to the destination DCT coefficients.

       block	 Pointer to an 8x8 motion-compensated block that is the difference between the reference block and the current block.

RETURN VALUES

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