Feeding D3D surfaces to Quick Sync encoder MFT

I want to encode video using the "Intel® Quick Sync Video H.264 Encoder MFT".Encoder initializes normal. The following code provides reference!

CHECK_HR(CoInitialize(NULL), "Failed to init Com! \n");

;
if (SUCCEEDED(hr) && count != 0)
{
    hr = ppActivate[0]->ActivateObject(IID_PPV_ARGS(&_pTransform));
    ppActivate[0]->GetAllocatedString(MFT_ENUM_HARDWARE_URL_Attribute, &hardwareUrl, NULL);
}
for (UINT32 i = 0; i < count; i++)
{
    ppActivate->Release();
}
CoTaskMemFree(ppActivate);

MFCreateAttributes(&pAttributes, 10);
hr2 = _pTransform->GetAttributes(&pAttributes);

I entered ID3D11Texture2D in the capture of the MFT event!!

hr = mpH264EncoderEventGenerator->EndGetEvent(pAsyncResult, &pEvent);
if (FAILED(hr))
    return hr;
hr = pEvent->GetType(&meType);
hr = pEvent->GetStatus(&hStatus);
pEvent->Release();
if (FAILED(hr))
    return hr;
if (hStatus == S_OK)
{
    if (meType == METransformNeedInput)
    {

        IMFSample *videoSample = VideoSampleList.front();

        hr = _pTransform->ProcessInput(0, videoSample, 0);
    }
    else if (meType == METransformHaveOutput)
    {
        //-------------
    }
}

The ProcessInput method is wrong:0x6B21DEED (mfx_mft_h264ve_32.dll) There is an unprocessed exception: an access conflict occurs when the 0xC0000005: reads the location 0x1234567C. what do I lack? Or is there a mistake in the code?

Hi Luo,

Were you able to solve the problem? I'm too stuck with the same issue. Please direct me if you found the solution.

Hi Donghui and Ramesh,

This should be MFT issues.

You can check it by running our sample code with Media SDK, you can install by download the latest version from following page:

https://software.intel.com/en-us/media-sdk after downloading, you can try to run the sample in the release package and see if you still get error.

https://software.intel.com/en-us/media-sdk

Here are some old posts, and let me know if it helps.
