HD 4600 VPP crop result different use two driver ?

[l_k_1]

Hi,

          I use lastest driver for my i7-4770 and count some vpp problem.
             Intel(R) HD Graphics 4600                    10.18.10.3345        vpp crop OK
             Intel(R) HD Graphics 4600                    10.18.10.3412        vpp crop CropX / CropY DO NOT USED

First, I decoded some frame use
            sts = m_pmfxDEC->DecodeFrameAsync( &m_mfxBS, &(m_pmfxSurfaces[index]), &m_pmfxOutSurface, &syncp );

Then，I do some crop parms settings

                m_pmfxOutSurface->Info.CropX = m_sInputParams_for_vpp.display_area.left;
                m_pmfxOutSurface->Info.CropY = m_sInputParams_for_vpp.display_area.top;
                m_pmfxOutSurface->Info.CropW = m_sInputParams_for_vpp.display_area.right - m_sInputParams_for_vpp.display_area.left;
                m_pmfxOutSurface->Info.CropH = m_sInputParams_for_vpp.display_area.bottom - m_sInputParams_for_vpp.display_area.top;

Last，I do some crop vpp
      sts = m_pmfxVPP->RunFrameVPPAsync(m_pmfxOutSurface, &(m_pVppSurfacesOut[nIndex_vpp]), NULL, &syncpV);

The code works fine with driver 10.18.10.3345, 

but with driver 10.18.10.3412 , no matter how I set m_pmfxOutSurface->Info.CropX / m_pmfxOutSurface->Info.CropY,

vpp crop from (top,left) (0,0)

Please Help!

Hi,

Yes, this was an issue in the driver that was fixed soon after it was discovered.  Newer drivers contain the fix.
