Hello guys,
I'm trying to scale YUV420 image (720x480) up to 1280x720 with the follow
code, but ippiResizeSqrPixel crashed at " t7_ownpi_CalcBorder8plC() + 0x5d6 bytes " .
// ( IPP version is 5.3 . )
void scale ( VideoData* in, VideoData* out )
{
IppiRect rectSrc = { 0, 0, in->GetWidth(), in->GetHeight() };
IppiRect rectDst = { 0, 0, out->GetWidth(), out->GetHeight() };
Ipp8u* ppSrc[3] = { (Ipp8u*) in->GetPlanePointer (0),
(Ipp8u*) in->GetPlanePointer (1),
(Ipp8u*) in->GetPlanePointer (2) };
Ipp8u* ppDst[3] = { (Ipp8u*) out->GetPlanePointer (0),
(Ipp8u*) out->GetPlanePointer (1),
(Ipp8u*) out->GetPlanePointer (2) };
Ipp64f xRatio = static_cast (rectDst.width) /
static_cast (rectSrc.width);
Ipp64f yRatio = static_cast (rectDst.height) /
static_cast (rectSrc.height);
int reqSize = 0;
IppiSize dstSize = { rectDst.width, rectDst.height } ;
ippiResizeSqrPixelGetBufSize ( dstSize, 3, IPPI_INTER_CUBIC, &reqSize ) ;
Ipp8u* pScaleBuf = (Ipp8u*)ippMalloc ( reqSize ) ;
in->GetPlaneInfo ( &srcInfo, 0 );
out->GetPlaneInfo ( &dstInfo, 0 );
status = ippiResizeSqrPixel_8u_P3R ( ppSrc,
srcInfo.m_ippSize,
srcInfo.m_nPitch,
rectSrc,
ppDst,
dstInfo.m_nPitch,
; rectDst,
xRatio,
yRatio,
0.5,
0.5,
IPPI_INTER_CUBIC,
pScaleBuf );
ippFree ( pScaleBuf );
}
Anyone has some suggestion about this issue?
Thanks very much.
