quesion about omx nf component

Hi,

My qusition is that my input video is 1920* 1080 yuv422,and I want to chage it to nv12. so I use the Nf component.but I find that sometimes there will be get a green frame. how to solve it?

the set omx nf code is under this: the m_inWidth =1920, the m_inHeight=1080.

bool setNfParams() {
if (NULL == m_pNfHandle) {
return false;
}

return true;
}

and the empty this buffer is like this:

int size = 1920*1080*2;

read(InportParamsPtr->ipBufPipe[0], &pBufferIn, sizeof(pBufferIn));

OMX_PTR pTempPhyAddr = (OMX_PTR) DomxCore_mapUsrVirtualAddr2phy( (uint32_t) pBufferIn->pBuffer);

m_pKernel->getEdmaInstance()->copy((unsigned char*)pTempPhyAddr, pPhyAddr,
m_inWidth * 2, m_inWidth * 2, size, 1);

pBufferIn->nFilledLen = size;

err = OMX_EmptyThisBuffer (m_pNfHandle, pBufferIn);

Thanks for your reply!!
