Hi
When the implementation of the
sts = m_pmfxDEC->Init(&m_mfxVideoParams);
return value is -4 (MFX_ERR_MEMORY_ALLOC)
May I ask what factors produced this result?
Thanks

Hi,
In your case Intel Media SDK failed to allocate the memory required to create decoder surfaces.

Your system has likely run out of memory. You may try to free up some memory used by other applications or try other lower resolution workload, or expand your system with additonal RAM.

I have the exact same problem but I do have enough RAM and when I run the intel example it's work fine.. but I changed it and now it's not working this way. here is my code for initializing decoder :
mfxStatus decoder::initDecoder(HWND window, mfxBitstream *Header) { mfxStatus sts = MFX_ERR_NONE; mfxVersion ver = { { 0, 1 } }; mfxVideoParam mfxVideoParams; mfxFrameAllocator mfxAllocator; mfxFrameAllocResponse mfxResponse; sts = m_mfxSession.Init(MFX_IMPL_AUTO_ANY, &ver); //sts = MFX_ERR_NONE if (sts == MFX_ERR_NONE) { sts = m_mfxSession.SetHandle(MFX_HANDLE_DIRECT3D_DEVICE_MANAGER9, m_renderer.initD3d(GetIntelDeviceAdapterNum(), window)); //sts = MFX_ERR_NONE if (sts == MFX_ERR_NONE) { mfxAllocator.pthis = m_mfxSession; sts = m_mfxSession.SetFrameAllocator(&mfxAllocator); //sts = MFX_ERR_NONE if (sts == MFX_ERR_NONE) { MFXVideoDECODE mfxDEC(m_mfxSession); m_mfxVideoDecode = mfxDEC; memset(&mfxVideoParams, 0, sizeof(mfxVideoParams)); mfxVideoParams.mfx.CodecId = MFX_CODEC_AVC; mfxVideoParams.IOPattern = MFX_IOPATTERN_OUT_VIDEO_MEMORY; sts = m_mfxVideoDecode.DecodeHeader(Header, &mfxVideoParams); //sts = MFX_ERR_NONE if (sts == MFX_ERR_NONE) { memset(&m_mfxRequest, 0, sizeof(m_mfxRequest)); sts = m_mfxVideoDecode.Query(&mfxVideoParams, &mfxVideoParams); sts = m_mfxVideoDecode.QueryIOSurf(&mfxVideoParams, &m_mfxRequest); //sts = MFX_ERR_NONE if (sts == MFX_ERR_NONE) { sts = m_renderer.allocSurfaces(mfxAllocator.pthis, &m_mfxRequest, &mfxResponse); if (sts == MFX_ERR_NONE) { m_pmfxSurfaces = new mfxFrameSurface1 *[m_mfxRequest.NumFrameSuggested]; for (int i = 0; i < m_mfxRequest.NumFrameSuggested; i++) { m_pmfxSurfaces = new mfxFrameSurface1; memset(m_pmfxSurfaces, 0, sizeof(mfxFrameSurface1)); memcpy(&(m_pmfxSurfaces->Info), &(mfxVideoParams.mfx.FrameInfo), sizeof(mfxFrameInfo)); // MID (memory id) represents one video NV12 surface m_pmfxSurfaces->Data.MemId = mfxResponse.mids; }; sts = m_mfxVideoDecode.Init(&mfxVideoParams); //sts = MFX_ERR_MEMORY_ALLOC } } } } } } return sts; }
