mlib_ImageTestFlags(3MLIB) mediaLib Library Functions mlib_ImageTestFlags(3MLIB)NAME
mlib_ImageTestFlags - test flags
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
int mlib_ImageTestFlags(const mlib_image *img, mlib_s32 flags);
DESCRIPTION
The mlib_ImageTestFlags() function tests the flags for a combination of the following predefined characteristics. Note that the result of
zero means the conditions are satisfied.
MLIB_IMAGE_ALIGNED64 /* data address is 64-byte aligned */
MLIB_IMAGE_ALIGNED8 /* data address is 8-byte aligned */
MLIB_IMAGE_ALIGNED4 /* data address is 4-byte aligned */
MLIB_IMAGE_ALIGNED2 /* data address is 2-byte aligned */
MLIB_IMAGE_WIDTH8X /* width is multiple of 8 */
MLIB_IMAGE_WIDTH4X /* width is multiple of 4 */
MLIB_IMAGE_WIDTH2X /* width is multiple of 2 */
MLIB_IMAGE_HEIGHT8X /* height is multiple of 8 */
MLIB_IMAGE_HEIGHT4X /* height is multiple of 4 */
MLIB_IMAGE_HEIGHT2X /* height is multiple of 2 */
MLIB_IMAGE_STRIDE8X /* stride is multiple of 8 */
MLIB_IMAGE_ONEVECTOR /* stride is equal to width in bytes */
MLIB_IMAGE_USERALLOCATED /* data space has been allocated by user */
MLIB_IMAGE_ATTRIBUTESET /* image attribute flags have been set */
PARAMETERS
The function takes the following arguments:
img Pointer to a mediaLib image structure.
flags Combination of a set of characteristics to be tested. It is formed by logically Oring one or more individual predefined character-
istics.
RETURN VALUES
The function returns an integer value containing results of test. Condition = 0 if satisfied; otherwise, Condition != 0.

mlib_VideoColorYUV2ABGR420_X2(3MLIB) mediaLib Library Functions mlib_VideoColorYUV2ABGR420_X2(3MLIB)NAME
mlib_VideoColorYUV2ABGR420_X2 - YUV to RGB color conversion
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ]
#include <mlib.h>
mlib_status mlib_VideoColorYUV2ABGR420_X2(mlib_u8 *abgr, const mlib_u8 *y,
const mlib_u8 *u, const mlib_u8 *v, mlib_s32 width, mlib_s32 height,
mlib_s32 abgr_stride, mlib_s32 y_stride, mlib_s32 uv_stride);
DESCRIPTION
The mlib_VideoColorYUV2ABGR420_X2() function performs YUV to RGB color conversion used in MPEG1 and MPEG2 video compression in the 4:2:0
sequence. It performs color conversion together with 2X zooming.
The luminance component is stored in Y, the chrominance components are stored in U and V, respectively. The size of the chrominance image
depends on the chroma format used by the sequence. In this sequence, the chrominance components are subsampled 2-to-1 in both the horizon-
tal and vertical directions in respect to the luminance component.
PARAMETERS
The function takes the following arguments:
abgr Pointer to the destination packed ABGR image. abgr must be 8-byte aligned.
y Pointer to the source Y component. y must be 8-byte aligned.
u Pointer to the source U component. u must be 4-byte aligned.
v Pointer to the source V component. v must be 4-byte aligned.
width Width of the image. width must be a multiple of 8.
height Height of the image. height must be a multiple of 2.
abgr_stride Stride, in bytes, between adjacent rows in the ABGR image. abgr_stride must be a multiple of 8.
y_stride Stride, in bytes, between adjacent rows in the Y component image. y_stride must be a multiple of 8.
uv_stride Stride, in bytes, between adjacent rows in the U and V component images. uv_stride must be a multiple of 8.
RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
