I can't find DeinterlaceBlend sample in samples folder...
My task - deinterlace video from analog TV tuner. I'm writing directshow filters and don' know how i can split frames to top and bottom, required for Blend and some other deinterlace filters. I'm not sure that it's possible.
My blend code:
{
//fill srcPlane from history buffer
const BYTE * pSrcPlane[3];
pSrcPlane[0] = pHistory[2];
pSrcPlane[1] = pHistory[1];
pSrcPlane[2] = pHistory[0];
IppiSize sizex;
sizex.height = size.height;
sizex.width = size.width * 3;
//all parameters by default
int blendThresh[2];
blendThresh[0] = 5;
blendThresh[1] = 9;
double blendConstants[2];
blendConstants[0] = 0.3;
blendConstants[1] = 0.7;
IppiDeinterlaceBlendState_8u_C1 * ppState;
int topFirst = 0;
int topField = 0;
int copyField = 0;
ippiDeinterlaceBlendInitAlloc_8u_C1(sizex, blendThresh, blendConstants, &ppState);
ippiDeinterlaceBlend_8u_C1(pSrcPlane, srcPitch, pOut, destPitch, sizex, 1, topField, 1, ppState);
ippiDeinterlaceBlendFree_8u_C1(ppState);
}
Maybe somebody can show my error or tell me better deinterlace method.Triangle and Medium doesn't help too.
