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
characteristics.
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.
