默认是播放yuv420,  Buffer size 为 width*height*1.5, 数据处理为

FORMAT = MAKEFOURCC('Y','V','1','2');
...

LPBYTE PtrY = buffer;

LPBYTE PtrU = buffer + width*height;

LPBYTE PtrV = buffer + (int)width*height*1.25;

for (int i=0; i<height; i++)

{

　　memcpy(lpSurf, PtrY, width);

　　PtrY += width;

　　lpSurf += ddsd.1Pitch;

}

for (int i=0; i<height/2; i++)

{

　　memcpy(lpSurf, PtrV, width/2);

　　PtrV += width/2;

　　lpSurf += ddsd.1Pitch/2;

}

for (int i=0; i<height/2; i++)

{

　　memcpy(lpSurf, PtrU, width/2);

　　PtrU += width/2;

　　lpSurf += ddsd.1Pitch/2;

}
...

422 处理时, buffer size 为  width*height*2

FORMAT = MAKEFOURCC('U','Y','V','Y');...

LPBYTE PtrY = buffer;

LPBYTE PtrV = buffer + width*height;

LPBYTE PtrY = buffer + (int)width*height*1.5;

for (int i=0; i<height; i++)

{

　　memcpy(lpSurf, PtrY, width);

　　PtrY += width;

　　lpSurf += width;

}

for (int i=0; i<height/2; i++)

{

　　memcpy(lpSurf, PtrV, width);

　　PtrV += width;

　　lpSurf += width;

}

for (int i=0; i<height/2; i++)

{

　　memcpy(lpSurf, PtrU, width);

　　PtrU += width;

　　lpSurf += width;

}...
