for (UINT i = 0; i < (UINT) nHeight; i++)
{
for (UINT j = 0, k = 0; j < nLength; j += 6, k += 4)
{
UINT y = pSrc[k];
UINT u = pSrc[k+1];
UINT v = pSrc[k+3];
UINTn1=511*u-6*v-64522;
UINTn2=48838-125*u-255*v;
UINTn3=506*v-u-64522;
pDest[j ] = (BYTE) (Trunc((y < < 8) + n1) > > 8);
pDest[j+1] = (BYTE) (Trunc((y < < 8) + n2) > > 8);
pDest[j+2] = (BYTE) (Trunc((y < < 8) + n3) > > 8);
y = pSrc[k+2];
pDest[j+3] = (BYTE) (Trunc((y < < 8) + n1) > > 8);
pDest[j+4] = (BYTE) (Trunc((y < < 8) + n2) > > 8);
pDest[j+5] = (BYTE) (Trunc((y < < 8) + n3) > > 8);
}
pSrc += dwSrcPitch;
pDest -= dwDestPitch;
}

用 ffmpeg 转换很快的。
