Ich kann die Daten von H264 erfolgreich mit Media Foundation Transform (MFT) codieren, habe aber leider eine sehr hohe CPU (wenn ich im Programm den Aufruf dieser Funktion kommentiere, habe ich eine niedrige CPU) Wenn ich die Kodierung bekomme, kann ich nichts tun, um sie zu verbessern? Jede Idee kann helfen

    HRESULT MFTransform::EncodeSample(IMFSample *videosample, LONGLONG llVideoTimeStamp, MFT_OUTPUT_STREAM_INFO &StreamInfo, MFT_OUTPUT_DATA_BUFFER &encDataBuffer)
{
    HRESULT hr;
    LONGLONG llSampleDuration;
    DWORD mftEncFlags, processOutputStatus;
    //used to set the output sample
    IMFSample *mftEncodedSample;
    //used to set the output sample
    IMFMediaBuffer *mftEncodedBuffer = NULL;
    memset(&encDataBuffer, 0, sizeof encDataBuffer);
    if (videosample)
    {
        //1=set the time stamp for the sample
        hr = videosample->SetSampleTime(llVideoTimeStamp);
        #ifdef _DEBUG
        printf("Passing sample to the H264 encoder with sample time %i.\n", llVideoTimeStamp);
        #endif
        if (SUCCEEDED(hr))
        {
            hr = MFT_encoder->ProcessInput(0, videosample, 0);
        }
        if (SUCCEEDED(hr))
        {
            MFT_encoder->GetOutputStatus(&mftEncFlags);
        }
        if (mftEncFlags == MFT_OUTPUT_STATUS_SAMPLE_READY)
        {
            hr = MFT_encoder->GetOutputStreamInfo(0, &StreamInfo);

            //create empty encoded sample
            if (SUCCEEDED(hr))
            {
                hr = MFCreateSample(&mftEncodedSample);
            }
            if (SUCCEEDED(hr))
            {
                hr = MFCreateMemoryBuffer(StreamInfo.cbSize, &mftEncodedBuffer);
            }
            if (SUCCEEDED(hr))
            {

            {
                encDataBuffer.dwStatus = 0;
                encDataBuffer.pEvents = 0;
                encDataBuffer.dwStreamID = 0;
                //Two shall after this step points on the same address
                encDataBuffer.pSample = mftEncodedSample;
                hr = MFT_encoder->ProcessOutput(0, 1, &encDataBuffer, &processOutputStatus);


            }
        }

    SafeRelease(&mftEncodedBuffer);
