Hello all,
I need a function in C converting from UYVY to RGB24
with MMX code to speed up the convertion. I do not
know anything at all about asm or MMX programming.
Could you help modifying the function below converting
from yuv420 planar to rgb24?
/*
* The type of an value that fits in an MMX register
(note that long
* long constant values MUST be suffixed by LL and
unsigned long long
* values by ULL, lest they be truncated by the
compiler)
*/
typedef union {
long long q; /* Quadword (64-bit) value */
unsigned long long uq; /* Unsigned Quadword */
int d[2]; /* 2 Doubleword (32-bit) values */
unsigned int ud[2]; /* 2 Unsigned Doubleword */
short w[4]; /* 4 Word (16-bit) values */
unsigned short uw[4]; /* 4 Unsigned Word */
char b[8]; /* 8 Byte (8-bit) values */
unsigned char ub[8]; /* 8 Unsigned Byte */
float s[2]; /* Single-precision (32-bit) value */
} ATTR_ALIGN(8) mmx_t; /* On an 8-byte (64-bit)
boundary */
