something was wrong with vpp use

i want to use vpp for color format convert 

everything was ok at the beginning 

i follow the step in vpp demo 

 

but when i get here 

it always return -15 

i check it  it means invalid video parameters

follow is my set

pParam->vpp.In.FourCC = MFX_FOURCC_YV12 ;
pParam->vpp.In.CropX  = 0 ;
 pParam->vpp.In.CropY  = 0 ;

 pParam->vpp.In.CropW =  m_BitInfoHeader.biWidth ;
 pParam->vpp.In.CropH =  m_BitInfoHeader.biHeight ;
  pParam->vpp.In.FrameRateExtD = 1 ;
    pParam->vpp.In.FrameRateExtN = 30  ;

    pParam->vpp.In.Width = MSDK_ALIGN16(m_BitInfoHeader.biWidth) ;
    pParam->vpp.In.Height =MSDK_ALIGN16(m_BitInfoHeader.biHeight) ;
    pParam->vpp.In.PicStruct = MFX_PICSTRUCT_PROGRESSIVE ;

    //  out put data 
    pParam->vpp.Out.FourCC = MFX_FOURCC_YV12 ; 
    pParam->vpp.Out.CropX = 0 ;
    pParam->vpp.Out.CropY = 0 ;
    pParam->vpp.Out.CropW = m_nDstWidth ;
    pParam->vpp.Out.CropH = m_nDstHeight ;
    pParam->vpp.Out.PicStruct = MFX_PICSTRUCT_PROGRESSIVE ;
    pParam->vpp.Out.FrameRateExtN = 30 ;
    pParam->vpp.Out.FrameRateExtD = 1 ;

    pParam->IOPattern = MFX_IOPATTERN_IN_SYSTEM_MEMORY | MFX_IOPATTERN_OUT_SYSTEM_MEMORY;

    pParam->NumExtParam = 0 ;
    pParam->ExtParam = NULL ;

 

 

 

sts = m_pMfxVideoVPP->QueryIOSurf(pParamm,request) ;

this always return -15

did i miss some thing  in my setting ?

thank you advance

Hi China,

VPP output format : MFX_FOURCC_YV12   is not supported!   If you want to convert from YV12 for NV12 then the input type should be MFX_FOURCC_YV12  and output MFX_FOURCC_NV12   

Also, the FrameRateExtD/N values are invered at in and output. Probably not what you want, and may cause issues.

Petter

Hi,

looks like the issue is that you're setting ChromaFormat to MONO. You should be setting this parameter to MFX_CHROMAFORMAT_YUV420 as illustrated in the Media SDK samples.
